PT4000 to PY3600 swap, how much slower on the motor? I'm not going to bore everyone with all the details but I need to go quicker w/o breaking the bank at the moment. N20 seems to be the answer. Problem: I really don't want to go a half second or more slower when running on the motor. How much slower am I likely to go on the motor if I switch converters? My motor is a stock bottom end H/C Vengeance package that has most of the power concentrated above 6500 RPM. It actually falls off the cam just for an instant right now after the shift even with the PT4000. Shift extension 5900 with the PT4000. I can get Ron to post up a graph of my unlocked and locked pulls if that info is needed to accurately predict this. I've been running 6.80's @ 100 in 1000ish DA air (3400 pound raceweight) for the past couple of months now and would hate to fall out of the 6's with this converter swap BUT I also want to spray a decent size shot. Any ideas? Thanks.
