Stage 1+ with 10.5 housing and test-pipe
Today's results are from a Dyno Dynamics dyno (not ours).
On 94 octane, the car put down 307whp. On 110oct, it put down 328whp. We didn't do a baseline with the EVO when it was stock. Nor do we have any results of other stock EVOs on this particular dyno (there are no EVOs sold in this strange country . So, how this dyno compares to ours is a bit unknown at this time. Stock WRXs, however, put down ~170whp so it can't read too differently from ours.
This car also ran 272in/264ex cams. There does seem to be a slightly loss in torque in the 4000-4500rpm where peak torque usually occurs. However, torque in the 5000 and up range is, at the very least, every bit as good as the more conventional cam combos.
More info later...
Cheers,

Now that is what I like to see. Tell David thanks for the turbo and 10.5 housing, and I have already started to bug him about getting the Vishnu crew back down to Big D again. On another note, I am polishing and cleaning up my head and going with 1mm larger valves. I asked Davis what our cars were running as far as injector duty cycle (we have the same map) and he said that it was around 87%. When I put a head on that flows a little better with the 10.5 turbo do you think that I will be close to maxing out the stock injectors? Would you recommend going a bit larger or should I just save the money? This combo looks very promising for some good torque.

You might want to do a search in the Vishnu forum. I remember something about it being off of and Evo 6. Just the exhaust housing, then bolted to the stock evo 8 turbo. A frankenstein turbo!!!!!!!
If i recall correctly, they said Shiv had one too sitting next to his desk waiting to be tested too. It's probably upstairs in the store room by now.

Sounds possible Shiv??

I think Smog made 273 hp w/ a stage 1+ on 91 w/ test pipe (?).
Ethan made 295 whp on 91 octane w/ a titanium turbo stage 1 plus. I think the ti turbo cost as much as an ATP kit to install, maybe $3000 installed.
The 3071 should also make about 295 whp on 91 also but will push to 323 whp(AZ3AR) on high octane and the Ti turbo craps out at 310 on 100. Ti turbo has stock like lag.
Vishnu also ran an ATP 3037 on 91 octane, stage one plus to 305 whp, 356 on 98 octane. Both with test pipe. 3037 can push more, but stock manifold maxes out at 6800 rpm and the power drops off 'til redline. Same cost as 3071. ATP kits laggier than stock w/ 3071 and 3037 rumored to spool very similarly.
David told me the intercooler might get additional 10 hp, but would be very useful with during heat soak situations.
So to answer your question, you might get 280 hp w/ test pipe and intercooler stage one plus. If the housing adds 10-20 hp, you are there. W/ cat, probably not, maybe 275 hp, 91 octane. IMO.
Might be a great way to go if you can find one. I think you can get them from Garrett, and should be less/easier to install. You'll be the guinnea pig........
