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

[jayroca]

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 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.

 

[16MustangVet]

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

 

[16MustangVet]

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

 

[chrsmi1]

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

 

[danomite02]

lol when did you hear that Vet?

 

[WolvesSoulZ]

Around 10-11 psi on 3.5 gen v, xp cam/plogdp combo.

Yeah just curious on a 2.8 I will probably be on 12psi since Im on stg 3 heads cam

 

[GTPpower]

I had 15 psi on a stock pulley gen v, l26, xpz, ported heads. Oh, at about 4k rpms.

 

[tweeder]

11 psi on a gen v and 3.3 with cai and speed daddy headers.

 

[Sven the Sexman]

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]

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?

No.

 

[Bluemagic]

Peak at 12 psi with 3.4 setup with the plog downpipe combo

 

[jayroca]

No.[/QUOTE

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

 

[Sven the Sexman]

It's better than manifolds...but not better than headers.
