Does the turbo S have any more horsepower than the regular 993tt?

Thanks

yes. 424 versus 400. ECU upgrade was the only performance change (in the USA), I think.

I have the S ECU, and I think the HP figure is underrated based on the stock TT's I've ran with.

I believe they also had an additional oil cooler, ft. spoiler, and non functional air intake in the frt bumper and the holes in the rear fenders for ? jrgordon is right, the 24 hp more is very conservative as all porsche numbers are. There were additional cosmetic stuff like calipers painted yellow and wheels with a different finish. Nice car if you can buy one right.

From the Sport Auto road tests of the time -which can be found here:
http://www.einszweidrei.de/

408PS 993tt 0-200kph -15.1s
430PS 993tt 0-200kph - 13.5s

Flat 6 magazine's numbers which are tests done on real (customers) cars throw the cat among the pigeons:

993tt 408PS 100-200kph - 9.44s
993tt 430PS 100-200kph - 9.04s
993tt Euro turbo S 450PS 100-200kph - 9.79s

I would tend to go with the Sport Auto numbers as being representative of a factory fresh 993tt so like with like. There is a BIGGG difference for just 22PS - obviously the shape of the power curve will influence ie more hp all the way along, but still

I thought the "s" had the k-24 turbos???

jrgordonsenior

Only the European version had the k24's, hense the 450 Hp. American was the 424 figure based on K16's.

thanks jr, that is an important distinction and a good guideline for realistic h.p. numbers,
depending on what mods a person does.
