15-16psi is about the most people have seen on built motors, ported heads, headers and camed applications. This TBSS AWd LS2 is making 10psi at 6500rpm stock heads, stock bottom end with a pretty good size cam, 1/7/8" kooks long tubes and dual 3" all the way out. We have a 3.7" blower and 7.5" crank(stock truck size) ATI 8rib kit so no slip. We live at high altitude so sea level it makes 12-13psi with the same pulley. Dont forget its a 6.0l LS2 so 10.8:1 cr so you would see just alittle less boost on a L92-LQ9 6.0l

yea saw it the other day dawm im inlove wit that tbss lol i know my truck has that same pontentail wit a pro charger its that i have my radix setup all wrong starting with a big stall and big cam

 

Big cam, big stall and 6500+rpm shift points are what procharger's needs.....

 

will shall c how the pro is gonna like the big cammer lol

 

had my truck on slowhawks mustang dyno yesterday, doing 1/4 mile pulls to check the shift points after the new converter. We were hitting 16 PSI on the 1-2 shift.

BTW most hated, I'm running a 224/228 cam and a yank pro truck 3200

 

I agree, 15.5# was about all I see with a 3# lower pulley, the prochargers also like a low restriction inlet duct




the F-150, 6 rib belt drive is another story ...

 

how much hp u putting dow

 

lmao...
gl with the setup

 

It just did 1/4 mile runs this time so it measured 490rwhp on my Mustang Dyno in 2nd gear.Truck did 240rwhp stock.

 

jusf bout a d1 from jed it has the 3.4 pulley how much boost will i make with that on my setup and will i have trouble witg slipage
