If you extrapolate from the Subaru results, it doesn't seem like that will be a problem at all .

As far as I know, there isn't an EWG T4 divided option available for the 7163 at this time.

Very cool, I may have a solution for your radiator.

do you mean jeff perrin's results on an early version with a single scroll 0.64a/r? boost-for-boost, it came in about 20 whp below a 7670 in the 450 whp. the best believable dj result i've seen on a 7670 with full supporting mods on a built motor is 575 whp. putting those two tidbits together gives me my 530 whp guess. have you seen any other results?

there is a SS v-band EWG version. no T4 TS as you said. i forgot.

text me some time.

I'm talking about the Subaru Stock location T3 results with 2013 release 7163.

Has anyone thought of or tried forward facing one of these turbos?

In particular the 8374 or 9180?

Did you get your turbo yet?

Not yet. Last update from Geoff was mid-March at the earliest.

I'd think with the length of these, clocking the whole assembly to be front facing would definitely have some packaging concerns.

Yes, FFtec did it a few years ago. I think there's pics in this thread somewhere.

Here it is, TS FF, nice build!

I looked at doing it with a 8374 and I don't think it was going to be possible with a 3" downpipe at least in a standard FF location. The turbo is just so damn long!

Got a baseline dyno pull on my Evo. BW efr 8374 at 26psi e-85 ended up getting 445hp/335tq uncorrected(mustang dyno)



Here's a link to the dyno pull

The one FFTEC did was single scroll T3 iirc

whoops! You're right, it's right there in the pics.

Abuse testing, maybe it was rhetorical but I thought I'd share either way.

As far as beating on the turbo, I think I have that one on lock with my 6258 equipped Yamaha. Before you discount it because its the 6258, let me explain why.

A Yamaha Raptor 700R runs 7psi oil pressure stock. We mod the pump and get 10-11psi at full pressure and basically 1 at idle. It is a 2 quart system with no oil cooler that also lubes/cools the clutch and transmission

I do watercool the center but it has 3 quarts of water between the turbo and the motor. Normal operating temp is 200-210 and the fan kicks on at 225*F.

My quad makes 103whp and has just over 110 hours on the turbo. For a car to match the amount of full throttle and full boost that my bike sees it would need a similar amount of time on a road course. I change the oil every other ride and I normally get 24-25hours per 3 day weekend of riding (I love to ride and spend more time on the quad than in camp). I run E98 which of course leads to diluted oil over time which is why I change it frequently.

The turbo single cylinder design inherently runs in boost at cruise. I am only running 12psi or so but it cruises at 2-3 and it does this non stop. The only time its not in boost is either decel or idle.

If the smallest bearing housing available has proven reliable under these conditions I really have no concerns about a larger center section with "normal" driving and cooling/lubrication systems.
