Speedaddy, are you a tuner? You sound like you are talking from experience.

Hey Bill:
See you tomorrow at 8. Starbucks at Johns' Creek next to the gym. I will be wearing the Black TT.

I want to thank RXDOC for meeting today to drive and compare cars. As a background, both cars began life as standard (K-16, 415 hp) 2002 Turbo's. The cars are equipped the same (sunroof, sport seats,etc.) and are in stock condition (seats, spare tire, tool kit...no efforts to lighten the cars).Both cars have upgraded suspension (RXDOC=PSS9, mine with H&R) and both have SSK (RXDOC with Techart undercar,mine with B&M in-tunnel).
RXDOC's car is equipped with Techart kit (ECU, intake, exhaust)..my car has the PSI k480 upgrade (ECU+BMC filter, stock intake and exhaust). Both cars had similar amount of fuel.
We conducted 5 runs in a safe, private location, 3 runs from +/- 40mph in 2nd, thru redline in 2nd,3rd and 4th, and 2 runs from 3rd-5th gear.
The result: A tie. Whoever got the jump (usually 1.5 car lenghts) held that amount until the end.
The interesting part: we drove each others' car, and the 2 kits have a different approach to the same end...the Techart car built boost slower, and had a big "push" at the top end, hitting 1.2 bar. The PSI car built boost quickly to 0.9, and held there with an occasional surge to 1.0 bar. Fortunately, we have the best application for each of us; top end for RXDOC's use at the track, nice, quick boost build for my street driven car. Needless to say, I am happy with my PSI kit.
RXDOC is a true enthusiast (between us we have 43 years of Porsche ownership) and I appreciate him taking the time for our "meet and greet". See you at Road Atlanta next weekend.

his car was at 550 and yours at 480, i am impressed, i have not done any runs on my car with anyone but if anyone close by has a good similar set up to mine let's go for a run, i'd like to see where my car stands as well.

RXDOC I am not saying this to criticize, but they are wrong, I would point them to this thread and ask for explanations if you paid the price of a 550 kit. I know people in their German HQ, let me know if you need me to put you in contact.
The PSI car seems to be running well where it should.
Thanks for sharing the drive. I thought there was a GIAC car as well?

Jean,
I think both cars are close to the same power...RXDOC can confirm what was done, but I believe it is a "Stage 1" ECU in his car, the only real difference is the TA exhaust, which sounds terrific (best part of the run : when he got the jump and I got to listen to that exhaust at WOT

Jean, no offense! I am VERY happy with ONLY 500(+ or -) HP! I was just going with TechArt "claims". The previous owner paid ($8600++) for the upgrades (thank you, PO).
The cars were pretty even on every run it was whoever got the jump, maybe it was my inexperience! This was my very first time doing this type of runs! Ever! The cars probably put out similar HP. I enjoyed it, but wouldn't be doing it too often!
I am off work today, Monday, as I am spending the whole day getting the car ready for two track day this weekend (brakes, brake fluid, harness, etc). Now if get passed often (or ever) at the track, I will be greatly offended.

I think Bill is correct about where the power increase shows up with these two cars. PSI has the power down low for some "stop-light" action. I think my car has the "longer legs" with accelaration improving north of 100MPH. Something we couldn't (shouldn't) be exploring on public roads. This the feature I really enjoy on the track, as you have this incredible acceleration above 100MPH. Makes other cars seemlike they are standing still!

One thing I wished we had done was to run the cars down to low rpm ( ie, 2k) in 4th and then WOT thru redline in 5th.
Would also be great to see how a "stage 1" car runs against an X50; X50 vs. GT2; 997S vs. GT3........

What does same gearing have to do with the rate of acceleration from, say, 100-150? So all cars "geared" the same should post the exact same times running 100-150?

Techart does NOT offer a 550hp kit for the 996TT with stock turbos period.
![evilgrin](https://rennlist.com/forums/graemlins/evilgrin.gif)
The kit that you have Dock is the 470 ps Kit, consisting of the typical air filter and its CF housing with a Motronic upgrade...Cost is 6800 Euros, close to what the PO paid at the time. The next stage has modified K16 turbos and pushes to 530PS. One more, the stock K24 turbos that come on the X50 will give you max. 510 HP with the Motronic upgrade.

I hope the above clarifies the results. We have to see a GIAC car run against these 2 now. Cost effectiveness, bang for the buck, etc..
