I have gone 125 mph in the 1/4 with the same turbo, cam, downpipe, intercooler, converter at 27psi in my stock stroke engine. Now with a 255 inch or so stroker, porting intake and bigger throttle body and air intake GN1 heads only needs 17-18psi boost to run 125 mph in the 1/4. The 3000 stall 9/11 lockup is tight on the street but 0-1 psi boost is 3100 rpm to launch. The stroker sounds healthier and there is much better low end grunt just cruising around town.
