Borg Warner S372 @ 27 psi??
Just dyno tuned my car last night and was wondering what could be wrong? The numbers are pretty low for the setup and im just trying to figure out the bugs.
Setup:
b18c1 std bore RS sleeved
CP 9.8:1 pistons
Eagle Rods
BC Ti retainers/dual valve springs
GSR cams
S372 std cover
PTE 46mm WG
Ram horn
4inch DP
3inch IC piping
31x11x4 IC
Fuel:
-8 feed
-6 return
Aeromotive AFPR
Dual walbro Full Blown kit
Bosch 1600's
Ignition:
MSD 6al
cap
SS blaster coil
NGK #8
Car dynoed at 552whp @ 27 psi and 318 tq.
These numbers seems really low to me any ideas, im going to check for boost leaks and WG leaks. Any other guys with S372 I would love to hear inputs and results.

Re: Borg Warner S372 @ 27 psi??
Boost leak can play a major factor in this, Had a buddy run a very similar setup to yours aside from (84mm) 9:1 Pistons and PTE6765.He Had a small boost leak around a coupler, fixed it and went to retune and gain 7-8 Whp. His setup makes around 670whp @ 20psi (still got acouple of bugs to work out). Also on a Gsr Cam

Re: Borg Warner S372 @ 27 psi??
Really wanted to go with Pro 1's but funds drained so had to settle with what I had available for now.

Re: Borg Warner S372 @ 27 psi??
It's laggy for a few reasons....
Small bore, I'm assuming GSR stroke, GSR cams, prob no head work....
It all adds up. Sounds like a possible boost leak issue too.
Who's tuning this and on what EMS?
JDM INC, I made 930 at 36ish. Sounds like you had issues too. lol

Re: Borg Warner S372 @ 27 psi??
Update! I finally had a chance to dig a little deeper and did a boost leak test. Found out the Tial Bov gasket tore and was completely gone, so pretty much metal on metal with the flange. Second was the throttle body had a minor leak as well. All in all, the majority of the boost was blown out of the BOV flange and never made it to the TB. I am pretty sure this had a major affect on HP and TQ numbers, how much? I dont know...if anybody has a clue throw out some values. I will have to redyno again...that means more $$$$
