I am so happy with my car that I thought I would share this with you.



I just got my car back from Precision motorsports after they installed their header/exhaust and got the car dyno tuned. The car feels like they swapped out the engine for a new one, it has made a huge difference. The car pulls hard through the entire rev range and feels so drivable, I can't wait for my next event at WGI next week. Precision had also installed the RS light weight flywheel and a complete new clutch a few weeks ago and that alone made a nice difference to the car at WGI nearly 2 weeks ago. So I'm really excited about seeing the difference in the car at WGI next week.



The peak torque is 205.238lbs at 4650 rpm's at the wheels with 181.874 lbs at only 3000rpm's.

The car also has 219.246 whp at 7000rpm's.



The engine is stock with 72,000 miles on it.

I assume you have the chip also. "A huge difference" Sounds like you got a lotta bang for you buck. Congrats and give 'em hell at the track.

Thanks, it did have a chip in it when I bought the car. It now has a custom tune done on the dyno which is what makes a nice difference in how the car feels and drives. However the proof will be in my lap time differences next week from 2 weeks ago <img src="/forum/images/smilies/968/rolleyes.gif" class="smilie" alt="" />

I understand dyno-tuning alone ( mods or no mods associated ) can make a material difference in power delivery. I am thinking about having that done but have not searched for a reputable shop locally that can do the job well on a 968. I hear it runs somewhere in the $ 300- $ 500 range, is that correct ?

If you would like to hear the system on the track I just posted a traqmate video

Gary,

Glad the mods had the desired effect. Will called me today for future stuff

Video at Thunderbolt is awesome!!!

Thanks, this car is going to be quite a project, a little bit at a time though as I get use to it.

Dan,



I asked about this at Bauer Porsche repair in Oakland, and Chris, the head mechanic and one who has raced n/a 944, quoted $700-800 for dyno tune and chip. I haven't done it yet, but his description and that of another customer made it sound much like the above post. Their # is 510-834-2772.

Dave,

You really don't need to dyno tune your car. Chip upgrades are available and make a really nice difference in low/mid power and top end.

Dave, thanks for the info . I do have an aftermarket chip - Speed 6 Racer X ( which was the winner of the shoot-out test a couple of years ago, BEFORE the RS Barn chip came on the scene ) and that in combo with the airbox mod and the BB catback exhaust produces pretty remarkable performance , in addition to the sound relatively identical to the one in the video clip..



Just did not know if simply dyno-tuning the car would by itself add another 10 hp and similar torque increase... if we're talking about 1 or 2 hp, I'm not going to bother spending that much for the job...

Dan,



I have had both RSB stage I and Stage II (with header) chips and believe that with all the testing that has been done is the best bang for the buck, at about 1/4 the price of custom tuning.



If you were the kind of person who absolutely had to have the very last drop of horsepower (sound familiar), you might get 1% more out of custom tuning.



If you simply want to spend $700-$800 to show off to your friends you could buy the new European chip that's the flavor of the week on another forum.



Regards,



Jay

i don't think there is 10hp there to be had with dyno tuning, over either the racer-x or the rs barn chips - there MAY be as much as 5 over the racer-x (i saw about that much at peak on my g-tech going from it to the rs barn)- the rs barn is pretty well tuned



that isn't to say there are no gains to be had in dyno tuning



factors that cold play into having custom tuning provide more increases are things like a lightweight flywheel, a different exhaust, engine wear, etc - all of these things could bring about different results on a dyno - any chip is tuned based upon the conditions and components at the time of tuning - dyno tuning will take into account the conditions and components at that time



that is why chip testing needs to be done carefully, all chips being tested on multiple cars, with multiple runs, throwing out the low and high and averaging the rest, with careful measuring of conditions of each test on each car, carefully matching those conditions, in order to be able to make claims of comparison - you can't just strap the car down, swap out chips, and expect any kinds of real data - the differences between them just aren't big enough to be able to do that



but i don't think the net gain is going to be all that much with dyno tuning either - worth doing on a race car, or if you are just focused on every last pony, but not on a street car - you'll get more out of using better fuel, and using iridium plugs and changing them more often

@Gary

Thanks for posting the vid! The telemetry feature is really cool <img src="/forum/images/smilies/968/cool.gif" class="smilie" alt="" /> Too bad the tach wasn't working - now we can't tease you about your shift points, [just kidding of course]. <img src="/forum/images/smilies/968/wink.gif" class="smilie" alt="" /> I have the RSB cat-back and it sounds similar to your exhaust.

Even with the few mods I've done to the engine, most are amazed that there's only 4 squirrels under the hood.

Gary,



Glad to hear you're so happy with your results. Sounds great, too - awesome video. I had never heard of Precision Motorsports, and am utterly amazed there's not one, but two apparently outstanding headers available for a car produced in such miniscule numbers. Out of curiosity, what made you decide to go with Precision's exhaust, as opposed to RS Barns'? Thanks.

I got a pm today from the previous owner who told me where he had left a tach wire for just this purpose. It will be really cool to have the tach working.



BTW,the 4 squirrels are on steroids now <img src="/forum/images/smilies/968/laugh.gif" class="smilie" alt="" /> .

Precision is a local shop in NJ, he knows Pete well. At the WGI event I was at with PCA in August, PMR (Precision Motorsports Racing) had 45 cars there that they take care of.



PMR installed Pete's lightweight flywheel with a sachs sport clutch recently in my car, perfect for a track car.

I'm looking forward to seeing what Pete does with a supercharger on a 968, that would nice.

So did PMR develop this header at their shop? I'm a little hazy on the details of how RS Barn's header came to be (by that I mean, I don't remember if RS Barn actually developed it in house, or outsourced the development), but however they did it, it sounds like they did an outstanding job, based on the dyno results. But I remember it being very expensive and resource-intensive, especially with having to deal with the engine's inductive resonance intake, so like I said, I'm amazed that somebody else has gone to all the trouble and expense of developing another header for such a low volume car, and apparently had very good success as well, based on your experience. But in any event, I'm glad you've had such a great result.

it's probably the same header - it was sort of a "joint venture" amongst a couple of parties - as it has been explained to me, pete paid for the development of the header, provided the car on which to do it, and paid for and conducted all of the testing of it - an exclusive deal was not negotiated - currently there are a couple of places it can be purchased

I was wondering if that might be the case. I found it hard to fathom that more than one person or group of people would go to the huge effort and expense of developing a header for such a low volume (albeit much beloved) car.

yup - it has somebody else's name on it, but don't think for a minute that pete wasn't deeply involved in that puppy - he just doesn't toot his own horn about it to those who would like to say otherwise - nobody pays much attention to them anyway, so why should he? all you have to do for the real skinny though is ask him
