V8KILR Posted April 23, 2012 Share Posted April 23, 2012 (edited) I'm running a MasterPower T70 (69mm compressor) Q-trim with exhaust AR 1.00 and it is just way too slow to spool with the TH400 with 3500rpm stall that I have just installed in the car. It was making 450rwkw when manual and is probably around 410rwkw now. It is making around 6 psi boost at 4000rpm and full boost by 4800rpm. I'm thinking about a MP T70 Q-trim with either a 0.81 AR or a 0.68 AR exhaust to suit the auto better. Any recommendations as to which would be best?

V8KILR Posted April 23, 2012 Author Share Posted April 23, 2012 The other option is a higher stall, perhaps around 4000rpm which would still be okay on the street. Quote Link to comment Share on other sites More sharing options...
V8KILR Posted April 25, 2012 Author Share Posted April 25, 2012 I've organized a 3800rpm stall converter that takes much less torque to flash the converter, as the one I had in their was designed for way more power/torque then my car is making at the moment. I will be putting this in the car in the next week or two and then I'll get it tuned with that converter, which should make a huge difference.
