| I wish I still had the pile of dyno graphs I used to have laying around as I had the stock turbos vs. the T25/T28's overlapped. There might have been 100 rpm worth of lag on the dyno; certainly nothing you would noticed while driving. Great pump gas turbo when I had them on in 1996. Good for 400 rwhp at 15 psi and 440 rwhp at 20 psi. Also, and don't laugh out loud here, but the car did run a 13.0 @ 119.42 with the 20 psi setting. Any boost higher than that would up the peak HP, but it would drop back to the same power at redline that it had made at 20 psi. Thumbs up! B.
