RS Barn VS OEM Flywheel
#61

Hey Pete,,,,,,,,Knock knock,, are you in there.???

Would it be possible for you to answer my question on an open forum.???

I know you visit here regularly.????



Is the flywheel you supply a straight swap for the original. ?? IE no MESSING about.??? THE last thing i want to do is start "buggering" about fitting it......Swapping things over , etc etc etc .....



Im trying to contact you on here as you dont seem to want to answer my e-mails....

+ As i live in the UK , this IS the "supposedly" easiest + cheapest way of getting in touch with you.....

Dave,

Sorry I missed your questions!!!

My flywheel is aluminum with steel replaceable friction surface. I went this route due to cost of manufacturing and ability to design a Spring centered clutch disc to go with it.

To produce a steel unit would have been a $45,000 development cost and opening order.

RSB Motorsport Flywheel is a "direct fit replacement for OE." If you use Spring centered disc there is one modification (5minutes).

[quote name='Vaino' post='45677' date='Jan 14 2008, 02:32 PM']I have the RSBarn clutch freshly installed in my 968. I only have some 80 miles with it. It does have a rattle on decel, in gear, from about 1800 rpm. Not teeth rattling, but notable. Its certainly liveable. The benifit of the fast spinup is far more important to me than a little rattle.[/quote]



Well, the LWFW has been in for a couple of weeks and I promised to report. Excluding the 260 mile drive home on the highway I have less than 100 miles around town. Vaino's comments are a very good summary. My car is mainly for the PCA playground and the slight noise is good trade off to me for the performance.

  1. The rattle is from about 1800 to 2400 RPM at most and only on full deceleration with foot completely off the gas. You can reduce it with slight gas.

  2. Of course, it's more noticeable at the lowest gear. Going around a parking lot in 1 tends to keep the revs in the "bad" range. It's pretty easy to get distracted and not notice when decelerating in third.

  3. It sounds a bit like a vibrating heat shield and NOT like the car is falling apart. I was afraid I'd get all kinds of ugly pictures in my head but that's not the case.

  4. I had the wife in the car three times and she never once mentioned the sound. Even, going around a parking lot. As a test I made sure not to point it out to her <img src="/forum/images/smilies/968/tongue.gif" class="smilie" alt="" /> .

  5. The acceleration is much more linear. Clearly better in first and second and I even feel a difference in third gear also.

  6. Sooo much smoother on downshifting with heal-toe. It connect so smoothly <img src="/forum/images/smilies/968/laugh.gif" class="smilie" alt="" /> .

  7. The car feels more "twitchy" when playing with the gas. It will be very useful in slaloms etc. We have an autox school in about 10 days and I'll be sure to test the new response on track.

  8. The new pedal feel is so much lighter than the old it's messing up my ryhtm for heal-toe; time for retraining. I don't find the faster rev up/down an issue.

  9. Starting from dead stop in traffic does require slight change in technique.


Pete had me lift the old and new flywheels+disk+pressure plate and there's quite a difference. A LOT of rotating mass, wow!



BTW -- I got my $ worth out of the old clutch. 100K and just getting down to a couple of rivets but a few microns of material left <img src="/forum/images/smilies/968/sleep.gif" class="smilie" alt="" />



Thanks Bob and Pete!

Actually Pete, yes i DO have some concerns.

As my GOOD m8 is a recent customer of yours,,

You say that the flywheel is an easy fit, with only a little fitting "challenges"....



Well after talking + discussing this at great length with both my m8 + his mechanic that fitted the units, i am going to have to dissagree with you..

It seemed the flywheel wasnt an easy fit. As the pick up points for the "timing" werent correct + they needed to machine the fly somewhat to get it to work correctly....All this costing him some EXTRA ££££ in fitting costs....

This was one reason for my original question....



It might be ok to sell the units on your side of the pond,+ have challenges,, but when things go a tad wrong with stuff shipped to the UK its a different story, usualy ending up in costing ££££££ in either postal costs or extra fitting costs....

Dave,

You seem to have the negative demenor to screw up a good thing. You are looking for problems.

I have heard of the mechanics decision to machine things and add to the bill.

I have installed 15 of these with the minor mod.

Dave I suggest you cut off 5mm of the guide sleve. A 5 minute mod.

The super mechanic machined who knows what for a cost of hundreds of dollars/pounds/euros.

Sorry,

Pete

Pete.

The last thing i want to do is "screw up a good thing"...+ NO im not "looking for problems"..

Im only bringing to light some of my concerns, after having talks with the m8 who recieved one of your flywheels...

After all, when he recieved his item, he was a tad upset that it was a alloy / fidanza unit, as the photo,s that were on your web site "at the time" were of a proper Porsche motorsport steel flywheel....And we can get the "fidanza" ones over here for about a similar price to the ones you are selling them....[ I see youve now changed the pics on the site].???



THE last thing i would want is to buy one of your units THEN have to start messing around fitting it..

In my book, when i purchase something, it should fit straight on , with NO messing about . As i do most of my own spannering....+ detest it when things dont fit right....After all time is precious... Well it is too me....



A minor mod.??? I dont consider having to reposition the "timing" probes a minor mod.????



If it is such a minor mod , then why dont you ship the flywheels out with this mod done.?? that way there would be no "mods" to do....+ there would not be any "bad feeling"...Just a suggestion.....

you should not have had to reposition the timing - i think the mechanic scammed you - this is a "plug and play" unit - if there was a problem with the flywheel, it should have been sent back - it makes me crazy when people modify parts because they think there is a problem, but fail to consult the manufacturer - at the very least, somebody should have picked up the phone and called pete BEFORE modifying it



the only mod required is not to the flywheel - it is to a component in the car that you remove to do a clutch job - in order for it to be shipped complete, you would need to send that out, have it done and then have pete send it back



or



pete would need to stock a bunch of them, mod them, and send them with the flywheel, further increasing the cost



the mod takes 5 minutes, and costs nothing - seemed the logical choice



by the way, because of the weight, the fidanza unit is not legal for racing over here, which is why this one was created - i suspect you would have similar rules over there - this unit is the same (within ounces) of the porsche motorsport unit, which allowed it to be approved by PCA for racing

The flywheel is a "Custom" piece and requires ordering 20 at a time to keep the costs down. The flywheel hads 6 more lbs of aluminum than the other piece you refer to. I did this for three reasons. One to match the weight of Porsches steel Motorsport flywheel for race legality 2. to reduce harmonics associated with lighter aftermarket unit. The S-2 used a harmonic balancer with it's lighter fw. 3 the light flywheels have a stalling issue when coming to a stop. The Idle control cannot react fast enough.

I was never told the mechanic modified the timing trigger. if he did, he undid something specific to my flywheel.

I want to come clean about mods needed to install RSB flywheel.

1. One mod is needed if you install with OE friction disc. Remove 5mm from the guide sleve

2. a second mod is needed if you use the RSB spring centered disc-again a 5 minute mod. It "Will" be incorporated in next production batch

Flash how can you flame the mechanic that did the guy in questions car dude, for what its worth the guy in question is a very good freind of mine also and i know of all the fitting problems regarding the flywheel, all this work was completed by a very well known porsche engine builder who probably has forgotten more than most of us know regarding the 944 and 968 model porsches, if its a plug and play unit why did the mechanic think that it needed to be modified in such a way, for what i know i dont think it was money orientated for sure, because it was a right royal PIA to do, and took longer to complete than the car was booked in for, therfor back logging other customers cars , which i'm sure you know in this world is'nt very good business sense, another point are the USA cars exactly the same as the ROW cars in this respect, just trying to establish the reasons for the modification if it is not needed. atb Pazzer, live from ther indian ocean. <img src="/forum/images/smilies/968/cool.gif" class="smilie" alt="" />

I was wondering about that as well. I'm also guessing that the mechanic/client did not talk to RSBarn about fitment issues before modifying stuff.

i am not flaming the mechanic - i am saying that there should NOT have been any mod needed, and it seems an all too common tale these days - it sounds very fishy to me - i am constantly hearing of mechanics that tell their customers they need things like chrome kanaeder valves or muffler bearings, knowing that the customer just doesn't know any better, or to make themselves sound like heros or they are doing more than they really are - admittedly i have become very jaded over the years - i just busted a dealer the other day for something similar



further, if he made a mod to the flywheel, to adjust for timing change, it would have required rebalance - therefore there should be a receipt from the machinist to back up the claim

I am the individual whom had the work undertaken on my car. An awful lot was completed in addition to the flywheel, work for which I may elaborate on in another post so as not to take this thread off topic.



I am a UK based customer of RS Barn Pete, I purchased a lightweight flywheel and spring centred clutch plate. Overall, I am satisfied with the products that were supplied, a couple of teething issues re installation – but ones that Pete advised me of, and also my mechanic, although one issue did take longer and was not expected –see later with regard to the timing position.



Bob – I took some offence that you consider my mechanic ‘scammed me’, although you were responding in a defensive manner to the previous posts.. My mechanic has gained his experience and reputation via Porsche motorsport/Porsche dealer, and I respected and accepted advice and decisions made by him on my behalf. His integrity is solid, and to be perfectly frank is just about the best I have experienced here in the UK – I have been let down in the past by more highly rated, better publicised and presented better than this one. Bob, personally, I would have posted something a little less confrontational along the lines of…usually the products are plug and play, did you consider phoning Pete, etc. No hard feelings though, hope it is mutual.



Rather than modifying the guide sleeve, my mechanic undertook alternative work which was my/his decision, cost me more £, but one he was more at ease performing – its simply down to personnel choice – I want to make two things clear here.



1. I am not qualified to say whether the reduction of the length of the guide tube is right or wrong – Pete is qualified, and I assume is satisfied with the modification, is fundamentally correct, is not detrimental to the performance of the car etc. My mechanic made an alternative choice, at his/my discretion, cost me more £, and he got on with it, which leads me to number 2.



2. I have spent an inordinate amount of time getting involved in the detail, sourcing, finding out how things work, fit, need to be modified etc on my extremely modified car. For once, I did not want to get involved in any of this ‘detail’, my car was having a huge amount of work completed, lots of parts replaced and my principal aim was to buy the main parts, hand the car over to someone, have the parts fitted, have lots of other consumables, preventative maintenance type items replaced etc (my car is tracked heavily). Hence, why I did not go into detail on every item to be replaced, modified etc – I wanted to deliver my car, collect it a week later and pay a bill from a respected and trusted mechanic – and one whom did a fantastic job with all the other work, replacing what he felt was necessary as he went along (the subsequent 150 miles on-track hard use was testimony to this). It is not often that you have the confidence to give such a mechanic a ‘free reign’ and not get carried away unjustly. Ignorance – certainly not, should I determine exactly what was done to satisfy this thread – possibly, but any reservations were taken up and responded to at source at the time in an expedient and professional manner, which from what I believe included a phone call to Pete on one of the issues.



I have since, some queries/have some questions that might be worthwhilst seeking answers to, to put everyones mind at ease. Initial thoughts upon delivery of the flywheel and clutch plate. Clutch plate appeared well made, but friction surface appeared to be of a smaller diameter than the original and does not achieve a full diameter contact area on the flywheel/pressure plate mating surface. Pete advised me that this is ok and should not be detrimental to its performance. Pete – can you advise on the clutch material, i.e., is it an improvement on the original, thoughts on longetivity, is there anything else you can add re the diameter.



Re the flywheel, yes, there were disappointments when I first opened it – I was under the impression that it was as pictured on the RS Barn site previously and not a Fidanza. As has been noted, I could have sourced a Fidanza for less money here in the UK (ironically I was speaking to the Fidanza UK supplier face to face just a couple of months ago). Something that I was going to ask – and I note Pete has already beaten me to it – and thought it would be very beneficial to clarify is that of the advantage the RS Barn one offers over the standard Fidanza. The RS Barn one weighs the same as the original motorsport item, as opposed to the lighter standard supplied Fidanza type. (is this with/without ring gear?) Pete has elaborated on the weight difference and the benefits of the heavier one (19lbs?) etc. I’m quite clear what benefit I have purchased – a lighter one for combined road/track use would simply have not been a sensible choice. The 19lbs appears to be about right for this use – the description of the previous poster of the experience with his RS Barn flywheel/clutch is spot on – and for those reading, and perhaps contemplating going even lighter – the effects noted would simply be exaggerated – perhaps ok for just track use, but not for road/track. If indeed there is a provable weight difference between the RS Barn one and the stardard Findanza, then I must hold up a thumbs up to Pete for this. This is notwithstanding the great work he/Bob have achieved with the spring centred clutch plate – I am quite sure that this has had a pronounced reduction on the drive chain clatter that I experience – again, I agree with the previous poster, but would add that it is noise from the rear of the car that you experience (subtle/limited noise at certain revs like a bag of nuts and bolts in your box)



The criticism I do have of the flywheel, is that of the timing marks, these without any doubt required alteration/some work. My mechanic knew what he was doing and could get on with it, but it did take some time to get it spot on whilst it was installed in the car – again, he is a perfectionist and had the flywheel in/out several times to ensure the fine tolerances he wanted to achieve were met. I did not have the time to return the product, I was under tight timescales, also the cost of returning/receiving would have outweighed the cost of remedy – if there had been a problem that a solution could not be determined/was not obvious, my mechanic would have been straight onto the phone with Pete. I think BigDave has a fair point – as he has, I too have undertaken much of my own ‘spannering’, and indeed, if the flywheels go out to individuals whom also undertake their own ‘spannering’, the work involved for ‘amateurs’ could be a problem. Myself, could cope with it, others may not be able to do so (equally you could also be asking why are they undertaking this work then). The point is, the timing marks are fundamental – in particular can TDC be addressed in shop, or even pre-delivery to yourself from the manufacturer?



One of my initial concerns with going with a Fidanza flywheel, was that of limited experiences of others – Porsche and other – whereby remediation/additional work has taken place to assure correct installation/operation. I am certainly not alone in having my opinion of this make ‘tainted’, but lets be honest, it is probably fed by a small very number of negative instances widely disseminated on the interweb forums.



Over here in the UK, people turn there nose up at Skodas – badge snobbery. Great cars, value for money, reliable, manufactured by VW, perfectly good machines doing what they should do well……but that badge. Are there similarities here with Fidanza – is this the image that is portrayed?



Pete, I don’t want you to think that we are asking awkward questions, being critical of your products etc – as you know from my mails to you, overall i have a huge smile on my face from the changes that you have brought about to my car, and overall I am positive about what you sell. I perhaps should have asked more questions beforehand, Caveat Emptor. Equally there may be learnings from this for us all, certainly the depth of knowledge of the products available for our cars will be pushed to a higher level and hopefully spark some sensible debate, and perhaps more importantly educated knowledge in lieu of the ‘internet experts’ that we become, emphasising the realities of as opposed to hearsay etc.



Whats the bottom line? Lightweight flywheel and spring centred clutch plate is a great performance mod, recommended – but only for those who are ok with the little noise/chatter – its not huge or prolonged, and only effects a small amount of the rev range. There maybe some that like a soft, quiet daily drive – but for those looking for some more ooooommph, go for it – one of the huge benefits for me is that it also highlighted the need for a new (again!) clutch plate (too much track driving?), and so acted as some well placed preventative maintenance. Have experienced a disintegrated clutch once, not again.



Pete - without prejudice, and genuinely all the best,



Frogisland.

Yikes,

I want to address a few things quickly. I was away last week and this week has been a blur trying to get caught up.

I descided to alter guide tube at zero cost and minimal time. Machining flywheel as an alternative is overkill both in cost and need. BTW only needed with spring centered disc.

Clutch friction material is an upgrade over stock material both in durability and grip. The center of the disc also has a thicker stainless spring which absorbs more of the clamping force when releasing the clutch.

My flywheel is documented at 18lbs with ring gear vs fidenza @ 13.5 lbs (published) with ring gear. There are also other changes I don't wish to discuss.

Both DMF and my flywheel have idenical locating recess to center retaining bolts.

The whole timing mark business is really baffling me. The DMF Flywheel timing marks are for reference only or for a quick check to see the timing belt is at least on the right groove.

When you "Properly time the cams those marks aren't used" There are only two things needed to time the cams. A dial indicator on the piston and a dial indicator on the lifter of number one intake at TDC overlap vs compression.

All for now

Pete

Thanks for your reply Pete



I should have added that your SCC plate looked much more substantial than the OEM one it replaced - after seeing the one taken out (lots of wear) and the small mileage that it had on it, i had a general concern that i would have to replace it again at some point (whichever manufacturer i went for)



Agreed on the guide sleeve vs flywheel machining - zero cost for the guide sleeve mod - both do the same job.



Also agree with use of dial indicator - i think one of my points is that if the change is undertaken in someones garage they may not use this method (dial indicators) to set-up timing, and would perhaps rely on the TDC mark.

The Fidanza and like don't have TDC marks, but they can easily be marked when lined up with the stock FW. All the FWs have an alignment pin (or should) so it can not be put on wrong. I don't see the lack of a TDC mark being a major concern.

What’s interesting here is how easily it is for everyone to go to great lengths after the fact. When a 5 minute phone would have done the trick....the whole point of this and other forums is to communicate about a common interest. At the point you or a mechanic have or had some questions....come on really like you really think no one in an environment such as these would not reach out and help....I know you guys across the pond are pissed from some misinterpretation but Holy Crap man pick up the phone...send some e-mails...light a fire...try smoke signals we all here to help!

Hey Pete, only defensive on the "scamming mechanic" dude, not giving anyone any s... dude, as you well know i'm a very happy customer of yours, and totally respect your products and the time and effort that goes into development of parts for these cars, was only concerned regarding the flywheels as this is my next step on the ladder to keep up with my colleague FROGISLAND, on track, car allready spins up a bit quicker out of the turns due to the RS BARN headers, one mod my english RHD counterparts cant have HA HA HA HA <img src="/forum/images/smilies/968/biggrin.gif" class="smilie" alt="" /> So a lightweight flywheel should give it some more, all the best Pazzer, we all love ya yanks aswell PEACE!!!! 968UNITED..... <img src="/forum/images/smilies/968/cool.gif" class="smilie" alt="" />

Speedracer / Rsbarn Pete. etall...

To start with i do apologise if my post were taken as being a tad agressive, it was not my intention to be so...

I was just trying to get to the bottom of a few "challenges" that my good collegue frogisland had encountered. As i am also contemplating a few "mods" of my own.. I just didnt want to get the "hassle" that he had [ or his mechanic]..

So once again sorry....



Pete. Ill be getting in touch soon, about a "modded" throttle body... Thats if youl deal / sell me one. <img src="/forum/images/smilies/968/biggrin.gif" class="smilie" alt="" /> <img src="/forum/images/smilies/968/biggrin.gif" class="smilie" alt="" />

If its better to talk via e-mail then ill do that, Its just that i tried a few times with no reply.

PS we love you too.....



BUT...



Flash..

Sometimes its VERY prudent NOT to butt in when you DONT know what went on....

I seem to remember a "challenge" you faced a few times over on 968.com whereby you and a few others had a run it, causing a lot of bad feeling.... I seem to think you did the same over on 968uk.???

So PLEASE do yourself a favour + think b4 BUTTING in on a subject that wasnt aimed at you.. The posts/ conversations were with me + Pete....

I know you have contibuted a lot to these cars , doing loads of mods, that i thank you for....



No im not going to take this any farther, even if you come back at me .....It STOPS here + now......
