when you guys ran the rides stock, what numbers where you posting? perhaps its cuz i have never raced a rear wheel drive so my launches suck but the car is consitently running 15's. i think even with the crappiest launch i ran a high 15. best was a 15.4 or 15.3. like i said, its a 5 speed but is there anything that might be keeping me from breaking into the 14's? is it even possiblt to hit 14's in the car? i have yet to lower the rear tire pressure. i wanna lower her for a few runs and see if that gives me a faster 1/4 time. also, i rev the car till shes bouncing off 3500 RPM. is this the sweet spot for a launch or should i try to get her more along the lines of 2500?

i have a 5 speed. the only performance mods i have currenty is the S&B intake and a magnaflow muff. i doubt the muff did anything for performance but at least she sounds mean and actually thats why i got her. stock exhaust never cut it for me.

185 is like a 12% drivetrain loss...great numbers, but most 5 speeds will dyno mid-high 170s. Autos 165-170 as you said.

210-15%(30.5)-179-5 sp

210-20%(42)-168-auto

rough estimates, but most stock dynos are around these numbers.
