Full Race Geoff

steven, this evo is 10.5:1 compression. check again, he previously tried 12.5:1 compression on the old 2.3L engine, maxxing out the old 6466 ets precision kit. boost threshold is not early for many reasons - starting the dyno ruyn at 4000rpm has a lot to do with it. Huge cams/valves/headport + az summer heat is brutal + dynojet loads less than dynapack + 1.45 a/r is gigantic for a 2.1L engine that only revs to 8k rpm are all factors. regardless it is lightyears better at lower rpm/midrange than the old T3 precision setup

edit: sorry i do not have any at this time. I did have some previously that I tried to fit it in an S2000, it will require some serious work and creative plumbing - once they are finally available. i couldnt figure out a good way to package in an AP1/AP2 fwiw

That explains a lot. I figured the dyno and it being in crappy Arizona with 4500 degree ambient temperature were the biggest factors. I didn't see that it was started at 4000rpm. The huge cams and breathing package will certainly kill lower RPM velocity though!

What kind of AR's are they even going to be targeting with the QSV setup? The internally gated style setups they were looking like they used seemed like it would be even more of a packaging issue than using a SP valve.

I can say that my topmount setup only fits a handful of ways, and they all involve the battery box, fuse box, and AC lines to be moved out of the way. I can definitely see that it isn't really suitable for a kit like you'd make since that's way too much work for a regular installer to expected to do.
I'd be happy to show you diagrams of what I got in solidworks but I'm betting you can pretty much imagine what it looks like. Pfab style, except 321 stainless schedule 10, angled outward slightly towards the strut tower and with about 3 degrees of tilt to have more equal length for cylinder #1 with 1 short radius bend and so that the downpipe clears with the added height of the SP valve. I might also have to clearance my frame to get my gigantic downpipe + wastegate dump tube to fit correctly but we'll see.

The other setup I was considering was doing a lowmount style setup like Ptuning but there's no way that huge BW turbo will fit down there.. It's kind of amazing that such a huge roomy engine bay all of a sudden feels so small.

If you're available you should give this car a drive once it's done. We've both been in a lot of EFR powered cars but never one with a QSV. If you've ever been in a QSV equipped 2j setup then I think you can get why I'm so excited to try this. EFR's already have amazing transient response so effectively halving the AR should make this thing feel like a rocketship. I can also say that I have another friend with a 9180 powered STI with a QSV that should be done who knows when (It's at our favorite shop in the world) but once that's done I'm hoping it'll incentivize BW to start releasing their QSV stuff. A free turbine housing would be nice too.

Now if I could only get BW to do an axial flow turbine with back to back compressor wheels like the Garrett dual boost setup...

Progress shots! Should be done with fab in less than 2 weeks. Chris at SOS convinced me to do a v-mount so I'm doing a custom SOS/My own stuff Vmount setup.

Big thank you to Chris for all the help thus far. Now if he'd only let me get my hands on that dead block he has lying around on a shelf back there...

Dat big turbo

Steven622

Stay tuned for the pictures of the V-Mount setup. Running a SOS radiator setup and a custom bell 21x9x4.5" core with custom end tanks. Should be heinous

It will be beautiful I'll tell you that !

Looking great !

4" Titanium exhaust w/ mandrel bends and a 5" tip

I wonder how loud this will be

Excited to hear it!
