What's the most psi you can run on a 6 rib setup without slip?? (Planning to add forged pistons for use with the stock ti rods)

I think a lot and take a deciton that I'll get a pistons now just to get more boost so how about 10-12Psi with the same old stuff.

Heads
VR blower cam
Kooks 1-7/8

so a pistons and pulley added to the list, also any recommendations about Forged LS7 pistons - stock rods need something to lower the compression a tad for some boost.

To feed that size motor with a D1 why not upgrade it to the 8 rib / ASTER bracket and max it out with a 8.65" pulley from CBR ?

Ah, he just said LS7 my bad... I still say you'll have to max it out to get those boost #'s on a 427ci.

car already made 607 only with headers, now I'm getting the heads and cam trying to reach the 700's but I thud why not to be direct to the 800's since I am going to open the heads that's why I choose the Pistons as the upcoming mood.

I don't think you'll be able to hit those boost levels with the D1, regardless of the belt. I ran a D1 on a 408 with a cam with super high DCR and at max blower speed it was barely touching 13psi.

What pulley combo are you running currently (crank and blower size)? How many psi are you getting?

6 rib drive pulley with stock crank blower, 6PSI.

Need the sizes of the crank pulley and blower pulley to see what rpm your spinning the blower at currently.
