I was not doubting that these people are serious engine builders and can make power - did you see the size of the exhaust tubing
I was just pointing out the intercooler issue which is close to my heart (pocket) since I blew good money on the same unit and I have proved to myself it doesn't work.

No hurt meant. Its just when you posted that you can potentially make 550hp with just stage 2 turbos and a remapped ECU on the thread where I am spending $$$$ to get less than 550hp sort of winds me up a bit

I had several conversations with Micke Svens (the engine builder mentioned by Rassel) and long emails. The guy is outstanding and his knowledge is second to none, really great guy and real in-house engine building. TB gotta get yourself a CTR again, with those numbers posted, forget dyno curves and I/C s

TB,
I'm not sure why you are wound up. I know the results that I've been able to get from Kevin's Stage 2 turbos using MoTeC and was exploring the possibility and interest for doing something similar with Motronics.
Consider that back in 1998 Andial produced a 3.8l RS camshaft twin ignition 993 turbo that produced 571hp and 522ft/lb at .95bar. What turbos did it use? 911 GT1 street turbos which are Kevin's Stage 1 turbos. The article is in Excellence #81, November 1998. This is consistent with my testing of the Stage 2 turbos and 540hp@.7 bar from the dyno sheet I posted in the other thread...

TB, I know, it was a joke
The CTR weighs around 3000 lbs. What has me a bit puzzled is that I do not get anywhere near those numbers posted for the 60-130 with its stock gearing. And I am using the same calculation than when I guessed 13.5 s for a stock 993TT and was reconfirmed later on the thread. Could be that CTR my gearbox info is wrong.

It's no coincidence that when you compare two cars with the same HP, the ratio of the 60-130 times are nearly the same as the weight ratios! For example, with the Ruf Turbo R and Ruf CTR (both have nearly the same HP):
(8.7 sec/6.5 sec) = 1.33
(3200 lbs/2400 lbs) = 1.33
In any case, my whole point of this thread was to get HP/TQ out of the performance equation. Let's see the real numbers! No more HP/TQ talk!

Mea Culpa. It makes perfect sense and I apologize for misinforming the board. My database is showing both the CTR and CTR2 as having the same weight.
I will test my 965 tomorrow and report back. Actually we have polluted quite a bit this thread , maybe another one should be started with times only and less blablabla which could be used as future reference.

This test helps eliminate throttle response and gearing issues. It's only meant to measure acceleration.
