ok i need to know how much hp can a stock b18c1 ignition hold. My set up is a b18c1 benson sleeve 83mm pauter rod, cp piston stage 4 head from laskey racing. Runing a full race turbo kit t4/t67 1000cc injector. I got it tune made 383 hp on a mustang dyno with stock ignition ... I am going back to turn up the boost and was worndering how much hp can the stock ignition hold..

 

I believe Mase did a car with 600+ on a stock ignition...it may have been higher though.
