New BW EFR Turbo Thread
I just brought it down to socal to get it tuned. It will be tuned before the 17th.

Obviously the 800 hp turbo on the 2.0 is NOT running 300 hp.
How is the top end? Does the power drop off at a certain rpm? Must spool like stock

Its a fresh time attack track build... It will bounce between Utah and California. As far as power, I would like to be around 500ish with instant response / great spool.
I have a feeling "kill mode" for me is going to be around 32LBS... As far as the track goes, I want to see what 25-30LBSs on e85 does.

Based on the spool on the 2.0 with the 8374, 4k full boost is really good, and with a 10% increase in displacement it would be even better. Yes, I would still recommend the 8374 to my customer, as customers always want what?? MORE. Ask anyone on here, eventually they will want more. Why buy a whole new turbo when that time comes?

What Im looking for is great low-mid range powerband and instant response.
As soon as I get it on the dyno I'll be happy to post the graphs. Like I said, from the limited testing (as its been on the car for two days) I'm in love with it.

to me it's not only static power curve (I typically look how close to 4000rpms the engine makes 400 lb ft), but the inertia of the wheel due to increase in diameter. As we all know increasing the diameter of the wheels (bigger turbo) increases it's inertia and therefore reduces it's ability to snap back to life (transient response). If I can hit my power goals with a 7670, then I'll have significantly better transient response and spool when compared to the 8374.
who knows... maybe with the 2235cc engine, E85, twin scroll 8374, and a well tuned EBC @ sea level I'll be able to have a static spool closer to 4k than what the FFTEC Evo did on an open .83AR turbine housing. But I would probably only consider that if the 7670 couldn't muster over 600whp.
i think I'd be more disappointed coming out of a corner and not having throttle response to rotate the car, than not having 50 or more whp at the strip.
I'll just start dropping weight out of my Evo once I hit 600whp. And it will be on an eternal diet of Titanium, Carbon, and aluminum.

I'm currently trying to decide between the 8374 and 9180 with 1.05 for my 2.2. Not sure if my transmission will enjoy the torque of the 8374 down low. (Its an evo 3 btw, so not as strong as the late model evo tranny)

They look very similar to the Keflord TX276HL's, which I can assure you, work very well in a 2.2 with Twin Scroll HTA86.
