standard size ( the one with the kit). its the non-up graded one. cant recall what exact size, but need to go smaller for E85

stock injectors, if u look back at previous post stock fronts.

Can't believe to get 286whp at 8psi (pulley is 95mm )
It seems they used 3.25" pulley

I don't know how the boost pressure should be measured, but if I subtract the ambient pressure from my MAP reading in my ECUTek logs I get peak boost ranging from 11-13psi. This is using the standard pulley.

Same here. I see 11-12psi at redline in my logs and a it 11 peak on my boost gauge. Majority of my powerband is a it 8psi

I accept 286whp at 12.5 is correct and 12.5psi (12.5-8=4.5=3*1.5) need 80mm pulley.
95mm 8psi
90mm 9.5psi
85mm 11psi
80mm 12.5psi

Mike tuned harrop kit and 270whp for 10psi and edelbrock on 2-3psi more get 286whp
it seems both edelbrock and harrop have equal efficiency
