thanks.

absolutely fantastic work doughy...

Looks like a very good transition between the housing and the waste gate, pretty close to a 45ish...

Do you think the .63AR hot side will limit you in respects to EGT and EBP?

I couldn't get above 20 psi on my .63ar .50 trim without encountering some pretty bad knock on 93 oct.. Im talking 25 degrees total about 5 degrees per cylinder.

I believe you have methanol injection so you shouldn't have any issue.

thank you matt, i bought a combo setup that aaron recommended...i do have meth and run on e85 so we shall see.... 

 

here is a comparison 20G VS GT3071R and all finished exhaust manifold to exhaust housing flow transition done to perfection...you can rotate that flange adapter and it lines up perfectly either way.
