Seems that he also developp an exhaust system for the Veyron :P Can't imagine the price as the stock system is already very expensive ...

on the Hennesey page it says it's "only" a 650 hp upgrade :hmm: Edit: seem like there are 3 options 590 650 and 700 hp ;)

im o they should put some different exhaust pipes, those 4 tubes look kinda dumb :?

Any performance data available already?

Some insane upgrades! :shock:

Love to see the outcome soon!

Hmmm Hennessey doing tuning to this car? Not sure how much experience they have with this engine but the turbo "upgrade" most surely means they swap out the VTG Turbo's for normal larger turbos to achieve those power figures. Also no pics of the products either. Is it their own stuff or they using an existing source from another tuner as such with Cargraphic and RS Tuning doing co-op with the 997 TT. I think if I were to do a TT upgrade I would use one of the tried and tested Porsche tuners for the job, Hennessey Vipers Yes! Hennessey Porsches...???

Some interesting stuff here. I wonder how real-world performance will be changed.

yeah as most have asked the kit is i think still in the final/uber close to production. He has had it there on his site for a while yet now you can order so i thought i would post. but as for a test look for Motortrend or Car and Driver for a test in the near future. :D

I agree on that.

Hennessey may be good at Vipers, and there's no doubt this 997TT can be a damn beast after going through the Hennessey conversion... but if I had to tune my car - don't doubt I'd do it if I had the proper Porsche - I'd go to the regular P-specialists - RUF, Gemballa, Techart... :wink:

yea, I would tust RUF the most with my car (aside from some of their body kits) as they have been tuning P-cars for a very long time. of couse, I just wish I could afford the TT, much less the tuning :wink:
