I went 114mph in the eighth with a 6680 @26psi and a hyd cammed 233ci GN1 headed engine. Imo you should be able to get at least 130mph out of it at 25psi with the p-trim. If not id take a closer look at the tune. 135+ with the big ex wheel at 25psi if the combo and tune is there.
bison thanks for responding, the car now has a ck built 400 with a brake and a pro torque converter. prior was a so so 2004r and an old art carr. doing the suspension and going back out.
