EFR 9174 + QSV build thread
So I figured I'd start just a build thread to keep all the crap about the S2000 contained. I didn't think it was right to put this in the SPAL fan bs thread so here's the details;
2008 S2000 w/ AEM Series 2
New stock shortblock
Heads w/ Supertech springs
ARP 625+ headstuds
OEM Gasket
SOS Twin disk carbon clutch
CDV delete w/ SS line
ID2000s
Magnafuel 750 fuel pump
Magnafuel MP-9950-B Fuel pressure regulator
15x15 Holley HydraMat PN# 16-107
Full Blown fuel pump hanger
Radium fuel rail
Flex fuel sensor
EFR 9174 1.05 T4 divided
Sound Performance T4 Quick spool valve
4" .049 grade 2 Titanium exhaust (Because why not?)
Custom 321 schedule 10 manifold topmount, equal length with short runners
Bell Intercoolers 4.5x10x21 core with custom end tanks
DEI Titanium turbo blanket
AEM Infinity 708 w/ Custom SOS harness
AEM IAT
AEM 3.5 bar MAP sensor
AEM 150 psi sensors for fuel/oil
Continental flex fuel sensor
Goals:
-Never ever have fuel starvation ever, screw surge tanks. Screw the extra wiring, the pumps lines and all that other crap.
-Outspool SOS GTX3582 kit, Note, they have a Mitsubishi .92? AR turbine housing and a custom compressor cover. This will be the hardest part because that Mitsubishi housing is tiny, and the short runner length means that they spool that turbo FAST.
Here's their kit with the lighter GT3582 cast wheel configuration, I couldn't find the GTX but I'd assume its a 100-150rpm difference at most;
-Have more top end than SOS kit - The 9174 flows close to 95lbs a minute the 1.05 housing means more turbine flow, period. That combined with my unreasonably large 4" exhaust should mean not only I sound like a diesel, but more top end.
-Have EFR spool + a QSV. Very curious to see what a 9174 with the equivalent of a .52 AR turbine side can do.
- Not blow up my stock block in 200 miles by keeping a very conservative tune for 91 octane, and having my E85 and "kill" tune separate.
Compressor maps:
The 8374 at 10 psi puts it at around 490-530 horsepower. This is a bit scary on pump but it's where it is. Somewhat worried about the urine that is 91 octane here blowing stuff up. At a "normal" e85 map of say 20psi it should be around 620~hp and at full kill say 27-28 psi it should land me over 700. Based on the short runner length, QSV and the AR, I'm hoping to see full boost at around 4000rpm.
The 9174 is basically the same as a 9180 with more backpressure and about 80rpm spool difference over the 8374. It's compressor map is ridiculous;
At 10psi on this thing skirts the bottom of its chart and should put me close to 520ish I'd guess. "Low" boost meaning 18psi depending on how far it goes in that map could put me around 650-700. I don't even think I should do a high boost map because this turbo will make more power than the block is capable of handling. My peak power goal to prevent my block from killing itself should only be around 730ish and I might hit that with under 22psi. If I built the block I could easily crack 850hp.
Here's an Evo with a 2L engine and the .92 AR T4 Twinscroll housing
His build is super simple and is a Full Race manifold w/ a built 10:1 CR engine and no headwork. I see no reason why my 11:1 2.2 and a .52AR equivalent shouldn't spool even faster.
Hydramat setup:
First I had my fabricator rip out the crappy factory swirl pot (Thank you CKit for these pics)
He did a great job;
Obviously will be cleaned first before putting in the mat.
Edit: Hydramat installed 7/31/15
With how much coverage the mat gets, I should be able to run extremely low fuel without any problems.
Edit 8/30/2015
Custom hood in progress. Have been waiting this entire month on some custom submersible E85 compliant line, but should have some completed shots hopefully by the end of the week as well as some more good news. Here's hoping it goes to fab by the end of next week.

The Borg Warner EFR 8374 is no more. Replaced with the new hotness, the 9174. This flows close to the 9180 @ 95lbs a minute but spools around 50-100rpm slower than an 8374 vs 400rpm for the 9180. Brace for boost.

The hood isn't finished but it's on for mocking purposes.
Things I noted: the 9174 is not running a MFT. It's clipped and the fins are at a different angle, but MFT it is not. I'll get a shot of the 9180's compressor wheel in comparison to see if it's any different.
Stay tuned for manifold, tuning, and my blown up block

Basically put, any part of the mat that touches fuel, it picks up from that spot due to some surface tension wizardry. This means that I will never have any concern over fuel slosh, or the swirl pot that's built in, or any other issues associated with the fuel pump not getting fuel.
