[QUOTE=cjperformance;11267585]I have the 4.13" pulley, and psi varies through the rpms from around 6.5 lbs at 5k rpm to 10.5 lbs at 6900 rpm shift point.
Not sure if you are talking about wanting 10lbs average or peak. I have been thinking about going with a 3.9 or 3.7 also and dropping the shift point closer to 6500. Interested in your results.[/
Definitely want to make a few more psi that the stock pulley. Im spending all this $$$ on the lt4 stuff I want to stretch it out a bit 😁
