Yep VF24 on STi 4 type R

flat4_ire

yeh, so is the vf24 really good quick spool up but the likes of td-o5 is better for more power??

anyone?

RoRu

What other mods do you have?

What boost is it running at?

Adam M

the front entry TD05 in most opinions is better for spool up and power!

engine internals have been upgraded:

steel crank
steel rods
cosworth pistons
lightened flywheel
tubular unequal length headers
3" exhaust (soon to be putting a blitz nur spec r on)
uprated actuator
k&n induction kit
its also got uprated oil pump
increased capacity sump (baffled)
ic tilt kit & splitter
boost is 15psi not sure what that is in bar

RoRu

Your engine will take alot more boost than 15psi/1.03bar what ecu/boost controler do you have.

vf 34 on your engine mapped properly could make 340bhp+ depending on which i/c, injector, fuel pump you have.

don't have a boost controller, ecu is factory one, going rolling road this week so will see what its producing now.
