Nice reply Felix. Forgive my rantings!
Oil problem with my car improved ,getting 0.7- 0.8 bar of boost,have covered 200 miles still seems to be a lot of oil blowing around the rear of car and some leakage at intercooler pipe I suppose its residual oil from syphoning problem,not much smoke on startup now even after a hard drive so fingers crossed.
On the performance note I think the 993tt is still today a true supercar I dont have many cars keep up with mine!.
Cheers Felix.

JJayB Lovely car!! Are they Krone 3 piece I have a front hub in my garage if its any good to you,brand new.

IMO, the main reason why the 993TT was single plug was because it served for FIA homologation purposes of the 993GT2 race car for the 1995 season.. Twin-plug was not allowed back then in GTS1 class and Le Mans among other.

Maybe this is complete bull**** but I think I read that we have some kind of law in Germany that accepts a 10% increase in power without going through all this regulations and stuff.

450hp * 1,1 = 495hp.

Maybe this is why ruf has chosen 490hp as a baseline?

With 1/4 tank of fuel, and slicker shifts got 8.7 secs for the 60 - 130 mph on Saturday at Bruntingthorpe With tank full, was seeing 9.1 to 9.3 secs.

Good time, Martyn. And no James Bond/Goldfinger experiences this time? And the car sounds absolutely fabulous on one of the PH videos I saw.

Some charts from today 2/2/08. Temp 73F, headwind 10mph. All runs made on the same Driftbox unit

My friend Rob's totally stock Ferrari 430F1. This was in Race mode and check out how quick the shifts are. Despite 2 shifts, the time is good. His car was chirping the 3-4 shift.




TTGasman's 997TT with Tubi exhaust. This was a 3 shift run which I think would be able to cut alot of time off by starting from 3rd and extending the stock redline to allow hitting 130 in 4th. The 4-5 shift added almost 1.5 seconds to the time. The Tubi sounded really, really good on his TT!




My Stage II 997TT, on a 93/104 octane 50/50 blend. I had 3 almost identical runs

eclou, thanks so much for posting! I've been hoping to see a 430F1 in action! Here's the 430 vs a CS. Contrary to popular belief, the shift times are about the same. The 430 is about 1 second faster from 60 to 130. However, I did 2 shifts and you did 3, so the comparison there is not apples-to-apples. I'll see if I have any 3-shift runs somewhere.

Great time on your 997 TT! It looks like 60 to 130 in about 7.9 seconds!

Out of curiosity, what times can one expect from a stock 993 TT setup?

Felix

11.5-12.0

Bill S.

I had a chance to run many 60 to 130s in a CGT with 91 octane (2-3 and 3-4 shift). Most times were near 7.7 seconds. Has anyone else done this?

TB993tt

I did loads of runs to 300kph at the airstrip - the 60-130 came out around 8s most of the time -being two people, slightly uphill and with a rough surface probably robbed a few tenths. 993RSR posted a 60-130 on this thread somewhere (7.4s from memory but he was one up)


Edit:
Found one I did on this thread, June last year driver only 7.8s -lardy gearchanges and a bit downhill but they all seem to be that way

Bill S.

Thanks for finding that. It seems like you would be in the low 7s with slightly faster shifts. What octane gas were you using? We have 91 (R+M)/2.

TB993tt

Bill, 99RON which I think is about 93MON - the downhill slope of about 3m probably contributed a bit.....
The average at Bruntingthorpe (rough surface -bit of TC) with 2 people slightly uphill seemed to be about 8.3s...
The fastest recorded two people in car I have seen is the Sport Auto test which managed 6.4s 100-200kph which is about 7.2s 60-130mph

Jean

I thought I would update the thread with my latest run.

This is the first all out run that I do with my stock gearbox, with the sequential gearbox I achieved a 6.6s. last year.. This run is 6.2seconds with one shift.

Temperature 29deg C. (84F) , tires Michelin Racing slicks on 2WD. The 60-130mph was achieved with one shift instead of two shifts as a result of the taller tires. Grip was decent, lateral Gs are still a bit wild, but nothing compared to my previous run of 6.6s on MPSC. Estimated full running weight 1510-1520 KGS (3330 LBS) . The most astonishing part for me is that I ran at less than 1 Bar of boost! The previous run was made at 1.18 bar and was slower

Some performance data to compare with high speeds available:
100-160KPH:2.8s/ Gemballa GTR750: 2.7s./ RUF RT12: 3.3s / Woodster: 3.48s
100-200KPH: 5.3s / Gemballa GTR750:5.3s / RUF RT12: 6.4s/ Woodster : 6.9s
100-220KPH: 7.4s / Gemballa GTR750:6.7s/ RUF RT12: N/A / Woodster: 9.54s
100-240KPH: 9.4s/ Gemballa GTR 750: 8.8s/ RUF RT 12:N/A/ Woodster: 11.54s
100-250kph: 10.6s RUF RT12: 12.0s. Woodster: 13.5s.

So I am about 1.4seconds faster than an RT12 from 100kph all the way up to250kph, that's really surprising despite my really poor aerodynamics!

Gemballa GTR 750: 0-300 KPH : 21.7s. 100-300KPH: 17.6S
RUF RT12: 0-300kph: 24.8s 100-300KPH: 21.4s
Woodster: 0-300kph: 27s. 100-300KPH: 22.2s.

60-130MPH: 6.2s.
60-150mph: 9.8s
60-159mph: 11.5s
