How many lbs of boost is the 3.5" pulley?

 

should be around 13-14 psi I guess...

 

DANG!!!!!! My engine would go BOOM with that on it.

 

not if its tuned right!

 

I have a ctsc aftercooled on my ap1....3.5=10.8lbs stock top and bottom

belt=4060385

 

Hi.
What mods do you have to support the boost,
I plan to go that way and plan to get that pulley,750cc injectors and i already bought a EMS and am waiting to receive it.
And how is the feeling compared to the stock boost and yours?
Is there a big difference?
And sorry to ask but how much did you pay for the pulley and the belt?

I have an aem ems (non uego), rc650 injectors, (RC now sells converter clips, you dont have to splice anymore!!!!)
get rid of the little comptech boost hider box...

im still on a stock clutch (not for long)..oh dear..

I notice the midrange punch... my vtech is lowered to 4200(thank you to CHURCH for tuning)...
it actually runs much smoother than stock (starts a little harder)....
because the power is so damn smooth it dosent have that violently fast feel to it...
my redline is set to 9200 rpm right now
the head has ti retainers and stronger springs...ide also throw in the new oil squiters to be safe..

the belt was um..somwhere near 20 bucks for the gatorback..gates makes em as well

the pulley was asp and was around 100 i think..(dont have the recipts in front of me

on a side note I think the crank pulley for the vortech is a different size than the comptech so the same pulley size will give different boost ratings..
