650bhp turbo?
We are looking to raplace our GT4088R twin scroll turbo on our time attack hawkeye. We want 650hp with the best spool possible..
I looked to bornwarner turbos, S300SX FWM looks good.
Any opinions or other options?

You'll not find better than the Clinic Billet 35R in normal rotated position, but if you are front mounted and not space limited then the Borg Warner EFR series may be worth a look.

I cheked there...there's a problem with the supply in the US on the ERRs, the next good turbo I was adviced was the borgwarner S300SX FMW, but I could not find more people to cross check results. Who supplies these turbos in the UK?

I does 610bhp at 1.9 bar, it is not too laggy since my engine is fully built high compression and well tuned, but I can always handle better spool up, the GT4088 is an old turbo, I'm looking for something with newer technology in it.

My billet 35r made 601bhp 565 ft lbs at 1.8bar. This was on a car with standard cams. The 35r billet especially the new generation ones are pretty hard to beat and on the right set up using the right fuel will do 700bhp and beyond. They shouldn't be overlooked that's for sure!!!

garrett do an 'x' range (i.e. GT30 with new blade design is a GTX30) which i believe spool quicker than the old range and it could mean you just buy a new core, so save a few quid too...... the guy on the phone at owen developments is very very helpful - and they give competitor discount
