I clicked your link, but can't access the pics b/c I'm not a member of that site.
Also, can you provide details on your turbo? The Garrett website doesn't list a 3040R.

so you have a .63 T3 turbine and you think you're going to hit 500whp.

600hp on a "conventional" engine; not a rotary.
i hate to come into this thread and just argue, but do a little turbo research (rotary specific turbo research) before you claim you're going to have 500whp. that turbo is small and the hotside probably flows less exhaust than the stock twins. it will not make 500whp easily.

So what your saying is that Garrett automatically ASSUMES that the turbo is going to be put on a piston engine and ONLY test it for piston engines? No.
Garrett does extensive testing on Rotary AND Piston engines before they make thier official numbers for that model turbo. Garrett turbos are very under rated as far as max efficiency.

ok i did a little more research on this infamous gt3040r and it appears that it is exactly what i thought it was, a GT series T3/T4:
T04S compressor cover, 82mm/56trim GT compressor wheel.
60mm/84trim GT turbine wheel.
here's an example site of some specs
http://www.revline.se/dbprod/product....asp?ItemID=11
yes thank you rich, it appears he had the turbine and compressor #'s swapped...
so in essence, that turbo is way too small for 500whp. it will probably spool up as fast as stock sequential twins and drop 25% of the boost, if not more, by redline. the compressor might be able to make it to 500whp, but the turbine is way too small.

ok, so based on the correct numbers, that turbo will not get you to 500whp.
edit: i'm not trying simply to argue here, i'm only trying to help you out. that gt30 hotside probably flows a little more exhaust than the stock twins... it will become a big exhaust restriction way before 500whp.

is there a mod that can edit post #26 and swap the word "turbine" with "Compressor" and "Compressor" with "turbine"?

Sorry to burst your bubble but i highly doubt you will come anywhere near 500whp on pump gas.. and you are going to have one hell of a time getting to 500whp on racegas and 20+psi.. with those specs you listed that turbo will be blowwing hot air after about 420whp.

This description from the link posted:
<<<Garrett GT3040R
Dual Ball Bearing "GT30/GT40R" Turbo assembly. T3 style inlet flange with 4 bolt T31 style exit. This turbo incorporates the same exact GT40 compressor wheel found in the popular GT35/40R, but runs the smaller 60mm w/84 trim turbine wheel from the GT30R. Appropriate for smaller engine where the GT35/40R feels too big, but the high amount of compressor flow is needed for the desired HP and boost levels. Large T04S style compressor housing with 4.00 inlet and 2.50" outlet. This turbo has a flow capacity of about 600HP. >>>
I hate to say it, but that hot side is going to choke you. 500 rwhp on a typical 35R isn't seen too often, with that tiny exhaust wheel you're fighting an uphill battle......

the compressor isnt nearly as much of a problem as the turbine; a gt30 turbine is about the same size as stock.
