I've been running a Rossler Terminator 3 TH400 with the standard 2.48 gearset for a few years now, and it has worked great...1.25 60's on a 275 Pro DR. I had my converter go south at the end of last year and put metal through the tranny, so I took it back to Carl to be gone through. My car was in the 8.40s range at 3300 lb race weight...maybe 1100 fwhp, not sure on torque...never been on a dyno. This year with my motor/turbo upgrades, I should be closer to 1300 fwhp and am wondering if I should be worried about the TH400 holding the power...especially since my 1-2 shift will be at 7500+ rpm versus 7k rpm of last year?? I have to be honest and say that Carl did try to talk me up to a Terminator 4 or going with a 2.10 gear set to reduce the stress on the drum on the 1-2 shift, but I just don't have $4k+ to throw at a tranny right now. I'm also wondering if I will be able to hook my 275 DRs with 2.48 1st gear and the extra power? Any real-world experiences with this transmission?
