Boost psi... whats you guys psi on which size pulley

**jayroca** · 10-23-2014

Just curious to see what how much boost you guys are seeing on pulley sizes I'm currently at 11 psi on a 3.0 pulley.. what's you guys boost looking like?

**Scottydoggs** · 10-23-2014

10 psi at 5600 rpm. on a 3.4 1.95 rocker, header set up.

thats via the dash boost gauge, as well as dhp scans.

16psi on 2.8......

Boost psi is JUST A NUMBER, the better the car flows the lower the number.

So your car on a 2.8 wont make the same as mine on stock heads.

Boost psi doesn't mean jack. Means even less if your comparing one engine to another.

3.4 pulley with 22psi

and a T70 turbo :P

**16MustangVet** · 10-23-2014

Does that car even run? last I heard it didn't.

**chrsmi1** · 10-23-2014

12-13 psi on a 3.5 on a gen v. with full headers.

**danomite02** · 10-23-2014

**WolvesSoulZ** · 10-23-2014

**tweeder** · 10-24-2014

**Sven the Sexman** · 10-24-2014

L36 block, ported heads, XP cam, SLP headers, Gen V, 3.4 pulley, IC'ed....sat at 6 psi. 8 PSI on a 3.2. 10 PSI on the 3.0.

**SgtMarshal** · 10-24-2014

full size phenolic intercooler, ported gen 3, 75 mm N*, gen 3 rotor pack with gen 5 coating, headers, and max out at 10 lbs of boost. also have a built transmission with a 2500 stall, not sure if that makes a difference.

Why no headers? That's a interesting setup with that cam do plog/dp flows just as good as headers?

Lol well obviously plog dp is easier but for the easier install curious to see if it flows better which is probably not
