Inexpensive way to go to 8psi

**The LS Avenger** · July 30th, 2001, 03:18 AM

Am I the only one who gets chills from hearing someone wants to boost from 6 to 8 psi and is bitching about the price of the PULLEY ??!?! Uh, what about fuel pump, injectors, FPR, etc etc etc. WHat about the cost when the engine goes ka-blooooey from extra detonation. Assuming your 6 psi JRSC is PERFECTLY tuned (truly a rare scenario) everything changes when you go to 8+). Quibbling about spending $150 for a pulley (or $170 for the Endyn stepper).

Sheesh, I must be getting old

If you are using the M-62 (gsr, si, type-r) the following diameters equate the different boost levels:

4.2 = 5.5 psi
4.0 = 6 psi
3.8 = 8 psi
3.6 = 10 psi

Just a small correction...the Si's engine is 200cc smaller, so those pulleys will produce higher boost levels on the Si (1.6 liter). The Si usually has these numbers:

4.2" = 6psi
4.0" = 8psi
3.8" = 10psi

It's funny though because I see 10 psi with my 4.2 inch pulley on my Si. Before you mention exhaust restrictions, I completely disconnected everything from the header back and the boost only dropped 1 psi at WOT. Good lord, that thing was freakin loud!!! eek
