Thought it would be fun to analyze and compare dyno graphs from a "typical" TT set-up to a "not so typical" TT set-up.
A good friend of mine just got his TT beast done by RSI just recently. His mods include GT35R turbo's with 1.06 a/r, fully built motor, fully done heads, G-force, Mark Williams, etc... My car on the other hand has twin 76GTS turbo's and all the supporting mods (too many to list here).
The following is a comparo graph to show what both cars are doing at 15-16 psi. Of course the 76 GTS car (my car) picks up more power per psi than the GT35R car and has the ability to make over 1,500 rwhp whereas the GT35R car is maxed out around 1,200 rwhp. Also, the 76GTS turbo's are just beginning to stretch their legs at 15-16 psi... Nonetheless I thought it was very impressive to see how LITTLE difference there is in spool b/w the two set-ups even though my turbo's are 13 mm bigger on the compressor side and much bigger on the turbine side as well. Just goes to show you how efficient the RSI TT custom package I have on my car really is. Enjoy...

p.s. the dip in the GT35R cars graph has to do with the fact that it spun the Michelin's on this dyno run...
