Evo8 2.2sr ETS 6466

This car finally got dialed all the way in this weekend. I put the motor together on this with clearances set to my liking. Also spec'd the turbo kit (With input from Aaron at ER on what hot side AR to go with) and fuel system. Considering the setup is lacking in some areas, it made awesome power. We revved it to 9k RPM, mostly because the stock intake manifold is dropping power by then, and that's about where we thought we should stop with 150mm rods. This was tuned by English Racing on the stock ECU- speed density with an AEM 5bar map, and dual mapped with a map switch.

On E83 fuel-
~745whp @42.5psi (the 765 number was in 4th)
626wtq

Engine-
-ER spec Wiseco 9:1 pistons
-Manley 150mm TT Ibeams, rebushed the small end because they were worn (reused from previous build)
-Eagle 94mm crank
-Buschur 272's (reused as well)
-Buschur ported Head (he doesn't do much)
-Stock intake manifold and throttle body

Turbo stuff-
-ETS twin scroll 6466 with 1.15 hot side and 4" intake, dual Tial MVS 38mm gates. Wastegate springs for 1bar. May up this to 1.1bar or 1.2bar the next time the setup changes since it made about 20psi on pump gas at 0 WGDC, so we have a little room for more spring pressure
-ETS 3.5" intercooler
-Grimmspeed EBCS
-3" exhaust

Fuel/Ignition system-
-FIC 2150's
-Dual walbro 450's
-AEM Fuel rail and 6an feed off the factory hard line.
-Stock FPR.
-Spoolinup COP

Transmission is an ER built ultimate ratio- 4.11 final drive, Evo9 1st and 5th, Evo8 3rd and 4th, and carbon synchros.

The stock intake manifold is REALLY holding this thing back. A Magnus V5 with a 75mm TB would help a lot up top. As would would GSC S3's and a better cylinder head. But the owner is happy for now. He runs 26" QTP's on 16" rota's. Car is full weight. Will see how low in the 10's we get, or if we can optimistically break into the 9's.

What a lovely setup. What engine management are you using?

Stock ECU, speed density. Edited the original post.

Love how it makes a 300whp gain in 500rpm. I could just see everything shooting from the front seat to the back, sunglasses, wallet, phone,...

Eagle crank will hold up? I have had 3 go out on us and crack. Two 100mm and one 88mm.

We made 870 whp 700 tq with similar set up but 2.1 on a stock oem ported intake manifold, 5 inch fmic and 3 inch intercooler piping though with 46 psi. Sweet set up though and love ER. At our boost level you prob would have hit the 800 mark and with our mods im sure 850 though maybe 870ish too.

English has made 1140whp on the Eagle forged cranks. Good tuning goes a long way. Everything eventually fails at this level. This isn't something that lasts even 25k miles if you use it for what it's built for.

Its nice to see how a 6466 dyno curve looks like with 272 cams since most builds like this one use the largest cams available.

Great build and awesome power. You have a nice combo and the results show it. CONGRATS!!! Surely with Magnus V5, TB and GSC S3 will hold the power better. Will move the curve a little bit to the right, but the gains will be so much more than the few hundred rpms to spool the 6466. Twinscroll surely works. Our build is almost the same, but I will tune it on 93 (e85 is unavailable).

Not really. Just a smidge more than a GSC S2. GSC R2's or S3's are a lot bigger.

That being said, I think cams and a manifold would move the power to the right 3-400rpm. But we could then very likely get 800+ out of it while still having a 4k rpm spread all the way to 9k. We don't want to rev it past 9k due to the 150mm rods.

very nice build and awesome power!

6an feed off the factory hard line
Are you running dual pumps off factory feed/return lines?

Yes. Factory hard lines under the car are being used. Only section that is 6an is from the hard line to the rail to eliminate the factory inlet to the rail that is a restriction. The primary walbro 450 is run on the stock wiring with hi/lo voltage rewire using a hobbs switch, and the secondary runs on the same hobbs switch. The hobbs activates around 10psi for the primary pump to get full voltage, and the secondary pump to kick on.

Gotcha. Thanks for the info!
