OK, then first on evolutionm, lancerregister and other evo forums

maybe the first with a dyno sheet.. .LOL

I know a build on lancerregister using a full race manifold.. but that is not done yet either..

Looking forward to it. Seems to be a race between you, me and Kiki to get this turbo on a car and running

there is one US evo getting my kit.. and that will be probably done before me... I still have to build the engine.. LOL

Well I'll have the kit next week, but still won't have a motor to put it on yet, so you guys have a huge advantage in this race haha. Motor is in the queue at the machine shop. I still need to pick out cams and think about getting a new clutch before it all goes back together though.

worst part will be waiting to run the engine in before full power mapping.. LOL

Corrected SAE Dyno. T4 EWG 1.05 A/R 8374EFR
2.2L 4G64, 94mm crank, 159mm rods, 9:1 Wiseco HD's
Evo 9 Head - GSC S2's, Kiggly springs, Manley Valves, ForcedFed CNC head, Magnus IM
E77 Fuel (measured), 3.5" exhaust, Garrett 24x4x12 Intercooler
385kpa Peak tapers to 335kpa
Our dyno reads spot on with a Dynojet, 13% higher than a MD so ~640awhp on a MD


Video of me roll racing. Took second overall

we install the 7163 fullrace turbo kit. It will need Turbosmart, internal WG. 26psi! here is a pics, it will tune by Evans Tuning with Halteck Platinem

RTerni, did you won 2nd with 8374 1.05 only? ppl think you need 9180 1.45... 8374 is real good.

It's not a street registered car, so I usually just do a dyno break-in. No real way to get miles on it.

there was some talk about WG actuator mount on the T4 IWG EFR and its position relative to the flapper..

here is the first prototype we made to position it right.. it also puts it in a position that doesn't hit anything on the engine when installed..

SO RESULTS!

E85 - 708hp - 24-25psi
91 - 450hp - 11psi







So, bright cyan line is the QSV completely open, dark blue and all the other pulls are with it closed until the boost target is reached.

The QSV itself seems to of gained around 5000rpm of spool, from 5500 to 5000rpm for 24~psi. What is most noticeable however is the additional torque throughout the ramp range. From 3800rpm it picks up around 20ftlbs of torque, at 4500, 40, 5000 90ft lbs. The spool is very soft feeling, it's not a huge kick in the pants like a twinscroll usually is. We didn't push past 24~ish psi because adding another psi only picked up around 14 or so hp and had to have timing pulled out. I'm thinking the relatively small turbine wheel (74mm, probably 65mm on the minor) combined with the 1.05AR housing is maxxed.

VTEC is engaged at 5000rpm and apparently didn't help much with spool up time at all. The other lines are the SOS GTX3582R kit. I defiantly think there is room for a better sized 67mm turbo with a larger turbine wheel.



My impressions with the EFR 9174 are actually kind of mediocre. It didn't really do as much as I was expecting. The spool is significantly later than anticipated, especially with a 11:1 CR and everything else into it. I'm also disappointed that I hit a "wall" at 700 with the turbine selection. I think a 9180 would of spooled the same but had more up top. My other option is a 1.45 housing, but honestly at this point I will probably keep it as it is and swap on a custom comp turbo when I swap in the built block.

I am not surprised at the disappointing results. The BW quick spool valve is nicely designed and a whole different ball of wax. the sound performance valve is a bad idea at best.

708 at 25psi. Damn those Honda motors flow some air lol

Let's also keep in mind that x622 is using a T4 open manifold flange, then a quick spool valve in to a T4 twin scroll turbine housing......
I don't get how you though this was going to be the most responsive thing out there with this setup x622. I'll dig up some logs to post later tonight but my 9174 with the 1.45 EWG housing reaches 40+ psi around the same rpm yours reaches 24psi while making a hell of a lot more power.
