what BHP?
Hi peeps,
What sort of BHP would i be running on my version 3 WRX with the following mods;
Full decat exhaust system. 3" bore on downpipe
Ported headers
Lightweight flywheel
walbro fuel pump
K&N panel filter
..........and if i were to remap using an apexi, what sort of bhp do we think id realistically get with the above mods on the standard VF22 turbo.
Cheers

I have the same mods on my 95 WRX less the flywheel but with an apexi induction kit and Power fc.
I got 282BHP which I was a bit gutted about considering the money it cost just to bring it to standard STI power. It does feel so much quicker and more responsive on the road but I expected 300BHP +

Next stage would be 550cc injectors and the Apexi MAP sensor (available in an Apexi boost control kit,
including its own 3-port boost solenoid). You need the 3bar MAP sensor (which plugs into the side of the PFC in the footwell) to go beyond 1.1bar.
With these fitted, the boost can be upped to a safe c.1.4-1.5bar (potential for 1.9bar, though!)
which, together with the mapped 550s, should give you an easy 300-310bhp. If you were to splash out on a Hybrid GT Spec FMIC,
then upto 340bhp/340lb ft is easily had (safe max level for gearbox).
At these sort of power levels it IS wise to go for the FMIC, to eradicate det-inducing heat soak issue of the less than ideal sized and positioned std TMIC... Nicknamed the interwarmer in rally circles.
