[quote name='Ninemeister' date='Mar 27 2006, 01:54 PM']Interestingly we exhibited our 968 at the Autosport International Show at the NEC at Birmingham in January, at which we had a visitor to the stand who had been part of the 968 development team at Porsche. His comments were that the team had designed the engine with high compression/low boost in mind, hence why the heads has such large intake ports, but because the results were spectacular Porsche had to cap the project for fear that the 968 would outperform the 911 and damage sales, so a hasty redesign took place which resulted in the production 968 engine that we now know. To say that he was excited by our results was an understatement.

You know, it makes me wonder what the 968 could have been if marketing hadn't gotten in the way of progress.

Thought you might like to see this Race Technology AX22 acceleration recording from the 9m supercharged 968 and a standard 968 (tested at 240bhp). The run was carried out at Elvington airfield in York whilst we were there testing a batch of standard and 9m modified 993's for a forthcoming Total 911 article.



It was a clear sunny day so there was no problem with grip, but we only did a couple of runs with each car to preserve the clutches, hence the 0-30 times could probably be improved but are representative enough for comparison. Both were driven by my business partner Marc, the standard car was a totally stock 968 Sport that myself and Marc recently purchased to sell on, ours of course is a CS fitted with a full roll cage, so the weights should be similar.



The interval times for each car were:



mph/SC/ Std

0-30/2.3s/2.9s

0-40/3.0s/4.2s

0-50/4.0s/5.4s

0-60/4.9s/6.7s

0-70/6.1s/8.8s

0-80/7.3s/10.7s

0-90/8.6s/13.0s

0-100/10.4s/16.5s

0-110/12.2s/19.9s

0-120/14.4s/24.6s

0-130/17.7s/30.3s



The timing results were independently verified by the Total 911 director Rob Mugglestone and were recorded on their AX22 meter, which if you are not familiar with it uses satelite location to record the speeds.

Thanks for that Colin - Marc had mentioned some of the numbers to me - the whole lot in comparison look blistering.

Colin,



I'm probably still a year away, but I might as well ask since my AC system is starting to get worse and worse, and my car is heading more and more towards track.....



1) Currently, what are the differences (if any) between your setup and the SFR setup? I'm located in California, so SFR seems more accessible....



2) What additional problems would one face if the 968 motor was to be in a 944 chassis -- if I recall, you did the install on Paul Riley's car, right? Different intercooler, perhaps?

Excellent results.



0-60 times are highly variable, but the 60-100 times are very interesting because its less brutal on the clutch and is more repeatable.



The 60-100 time of 9.8-seconds for the standard 968 is right in line with other independant tests. See http://www.weissach.net/924-944-968_RoadTe...y.html#968Coupe for those results.



The 60-100 time of 5.5-sec for the supercharged 968 is squarely in 996 TT territory! Very, very quick. See http://www.weissach.net/996-997_RoadTestSummary.html

I would love to do this but no AC system is a problem. Is there a way to do this with an AC system?

Any way to attached mpeg file so that the sound of sc engines can be heard? Very interested in SC, don't really care about air con but have heard negative comments about the clatter noise.



Thanks,

Heh, I'm waiting for a few things, both audio and video <img src="/forum/images/smilies/968/smile.gif" class="smilie" alt="" />



Flash recorded from performance muffler sounds I'd still like to hear. I'm sure they sounds great, but I'd like to make sure <img src="/forum/images/smilies/968/wink.gif" class="smilie" alt="" />

I'd also like to hear the whole drivetrain ringing caused by light flywheels. Despite all the various descriptions of what it sounds like, I just can't seem to picture it.

No clatter at all. I was out at Oulton Park circuit last weekend - a friend got some video that I'll try and get from him and post; all you could hear was a "whoosh" on the pit wall as I went past at full chat, and the noise in the cockpit is barely noticeable in daily use, but a little more prominent on track.



Just for the sake of clarity, my 9M charger runs 370 horse, rather than the full 420-430 horse.

I can vouch for that to as i was at oulton park too and frasers car just wooshed by on full chat down the pit straights. I've also been in 9m's car out on the road and the only difference from standard in noise terms is the blow off valve hiss, performance wise the car is incredible just keeps on pulling, and that was in its development set-up running around 350 ish bhp, but now with 420 it must be AWESOME, well done 9m, as for lightweight flywheels 9m have manufactured their own from a original racing one for the 968, quality peice of kit by all accounts, not cheap though but quality ain't is it. <img src="/forum/images/smilies/968/cool.gif" class="smilie" alt="" />

Chris, nice to see you on the Duke, sorry you'd scooted before I pitted or you could have come out for a spin if you fancied it. Yeah, the flywheel ain't cheap, but being single mass it'll last and last.

Thanks Fraser for the response. What's the additional service like for the sc? Any issues with the belt slipping? I mentioned the idea of the sc to my mechanic and the response was not that positive. If I lived by ninemeister I think it would already be installed. Want to make sure that the sc is serviced properly by someone who has a good working knowledge of sc. There really doesn't seem to be any other way to increase hp that substantially on the 968.

You're very welcome bj. I'd an overfuelling problem caused by belt slip, but having the belt tightened a fraction cured this.



The charger has its own independent oil supply and cooler, and I think the oil change interval is recommended at either 40,000 miles or 100,000 miles - I can't remember which! (Colin?)



Any idea why your mechanic is reluctant bj? You can get a couple of extra HP if you have the management chip reprofiled, and in theory you could get more brake if you did developmental work on the ports etc, but the charger gives you huge bangs for your bucks, and the 9M one has run for over 2 years without issue.

I seem to recall there being mention that the 9m single mass flywheel being roughly the same price as the OM DMF. But I couldn't actually find it listed on their website <img src="/forum/images/smilies/968/ohmy.gif" class="smilie" alt="" />

Fraser,



Need to explore the reluctants of my mechanic in more depth. His strategy seems to be upgrade the header, exhaust and chip. Might be influenced by preparing 944/968s for club race rules. Secondly, I don't think he's aware of the development that's been done with sc.

The 968 is going in for c/v service. I'm going to have a leak down performed to determine the health of the engine at the same time. Want it in tip top shape before sc.

Certainly a free-flowing cat will help bj; any sort of head work (polishing, flowing etc) will help too, but extensive developmental work on stuff like the manifold or inlet ports I believe is expensive. An engineering company in the UK near me reckoned they could get to 320 horse without s/c, but when you looked at the work they were going to do its still a £5k ish deal.



When I had mine charged, 9m stuck it on the rollers first to see what brake the engine was producing beforehand (anything under 220 bhp they recommend you have remedial work done on the motor before it gets charged).



Any info I can provide to you or your mechanic I'm happy to, however Colin and Marc at 9m can give you far more relevant and succinct info. I just think its a great upgrade for me, then again I'm not fussed about stuff like aircon, keeping the car like it was when it left the factory etc. If I hadn't got the charger I'd have gone the GT3 route - much harder to explain to my wife, especially when I went out to buy a new bathroom and came back with the 968.



Kind regards,



Fraser.

Fraser,



I agree. Other hp options can end up costing the same as an sc with very little increase in hp. Up until last year I was going to trade in the 968 for a 911. Decided to keep the 968 because the most enjoyment I have is when I'm out on the track. So I'm doing some mods with the money saved (no need for a bathroom!) Have upgraded the suspension -konis, sway bars, lowered, debating wheel size change (currently have 16s). Want to acquire pole position recaro seats and ultimately address the hp with sc. Thans for your help and info.

bj, you're most very welcome. We're going along similar paths - I've had the suspension uprated to KW3 all around and had the car lowered at the same time. Braking at the front is provided by 928GTS calipers [big blacks] with RS discs (rotors). A full safety devices cage has been dropped in, and I got a pair of Recaro poles, one of which I fitted so far.



Wheels are 18" BBS Trans Am.



Let me know if you want me to mail you some pictures, and let me know how you get on.



Kind regards,



Fraser.



ps - did you find the sway bars make a big difference? I'm thinking of getting some to stick on just for when I'm on track, but I can't say its a high priority at the moment - I'm more interested in a limited slip diff if I can find one for sensible money.

Is that 9m flywheel speciffically for racing? Or is it suitable for daily driving as well?
