Wow..that's just sick.

It's amazing how much power can be added by simply putting on a Cobb oil fill cap and pulley cover.

I believe Dom said it was on 27 PSi, that's also the setting on my EBoost2.

This is what Synchronic recommends when using the BOV in the VTA configuration.

^^^Less of a chance of oil mist everywhere in the engine bay after some time if you have a bit of blowby etc.

If you had that much blow by to have oil mist coming out of your BOV you'd have an intercooler full of oil and much more to deal with than a filter on your BOV.

Yeah, it's about the same as what you have been running for a while now

So does your setup spool any faster? I have this sneaky suspicion that the 2" crawford pipes look cool and all, but hurt spool on my setup...

If you think about it, it's a 2.6l engine, it has ported heads and an HTA wheel, the latter is debatable, but the other two should help spool, but somehow this setup spools slower than my previous 2.5l setup...

It's the combination of the heads, cams, and turbo. It's all shifted your curve to the right. No biggie.

The 2.6l is only marginally larger than the 2.5l. If you calculate the cubic inches out, it's not much.

You got power hungry and shifted your power to the right. Run it out to 8k and you still have a 3k-3500rpm powerband. (same as me, same as a stock sti). You just got a wicked area under the curve.

(I'd bet if you kept the head ports near stock but ran the cams.....you wouldn't have shifted the curve as much.....but you wouldn't have as much power either)

I want that crank. Hello Dom?

Throw some C16 or Q16 at it and get it retuned and make sure to post your face as you drive it for the first time.

For comparison purposes...

http://www.iwsti.com/forums/gd-membe...ed-ftw-42.html

gsc stg2 cams, Topspeed head porting, Hta 3582R, 2.5L

That being said and not to be negative but it does look like your power comes on 300-500 rpms later and falls fairly hard up top for some reason, have you asked your tuner why the power falls like that on a car with cams and headwork???

Too small IC piping.

You can only flow X amount of air through a 2" pipe at 27 psi. Doesn't matter how you shake it.

That boost onset is about 1k RPM late. Check to make sure you have the valve seat installed in the EWG, then check for leaks.
