Hi all

I'm thinking of modding my 2007 GB270 (based on WRX) up to around 340bhp/370 lbft. I've already asked Duncan at Racedynamix about the reliability of the gearbox and clutch from doing this.

Has anyone had bad experiences from putting this much power through a hawkeye WRX drivetrain as I understand it is not as strong as the STIs?

Thanks

The hawkeye WRX boxes have been re-engineered from the other TY754 boxes and they are much stronger than the blobeye and bugeye boxes. They have been proven to handle up to 400/400 without any issues. That said the 6 speed boxes are much stronger than the 5 speed boxes but at those power and torque levels your box should easily cope.

Thanks Arch, first time anyone has mentioned that the hawkeye boxes are stronger.

Ive upgraded my hawkeye to 340 bhp, and i havent had any problems, saying that ive only done 2500 miles since the upgrade, but so far so good.

I know two people at mid 300's that have had issues...

One has gone dog-box, the other for a six speed.

I ran a TY754VN4AA blobeye box at around 400/400 in my race RA with serious launches without breaking it, after some advice I was going to a hawkeye box but ended up moving the car on a lot further than expected so went to a 6 speed. These hawkeye boxes have been holding up well at 400/400 but as with everything there are no guarantees

Very good figures there mate, what mods have you done?

My hawk WRX is running 340/340, but might up it a bit when the Ecutek race rom is available.

still crossed and still ok warm the car up before hard drives and keep oils fresh ie change oils.

What on earth is a dog-box Dunx?!?!?

Is it the bhp or torque that is the biggest factor as my torque figures are already high (360lbft) but bhp is only in the 290s currently...?
