Looks like a stock turbo the way it responds. Very nice powerband. I am sure it is a badass. Congrats!

Can't wait to see your E85 results. Awesome pump gas numbers and powerband!

Evo 9 MAP 2.4 CBRD BBK-B

Ibelieve this run was 3rd gear, I'll check with my mechanic. I have the Map O2 housing recirculated, GSC R-2 cam. The compression ratio was supposed to be stock 8.8 but on my build sheet from MAP is says 9.7. I got a headache trying to apply Boyle's gas law but I'm assuming with the larger displacement that should get me close to 8.8. Apologies to all you engineers.

We don't have E-85 here so Meth water injection was the only alternative for higher boost.

David.

Evo MAP 2.4 CBRD bbk-bb

I checked with my mechanic and this was a 3rd gear run. Spool is probably helped by the Jack's stage 3 transmission. It has the evo 8 3rd and 4th gear with a 4.00 final drive gear. It's in between a 3rd and 4th gear run.

Thanks for the positive comments.

David

Those #'s are great for just 24 #'s of boost. The 2.4 also makes it spool quite nicely, almost stock like! Get that meth flowing so you can run some more boost.

I'm very interested in seeing more of this setup. I love the curve...much like the 2nd poster mentioned: it looks like a stock evo curve but just way more power and tq....the response on this must be ridiculous and it will just keeps pulling. That and the fact that you are only at 24 psi once you spray some meth and up the boost and see what timing you can get away with. That said I wouldn't be surprised to see you in the 530-550 whp range.

That's a beautiful curve! I've been pretty set on a Green, but this is making me think otherwise.

I have the ported cover. My mechanic hasn't given the car back yet. He wanted to change the trans and engine oil but he did not mention any surge.
