Location aside, the big reason for the high HP rating is the option of a 67mm (935HP as rated by manufacturer) turbo with a large T4 turbine.

It is simply crucial to have a large T4 turbine on these engines, and the test result I did last year have confirmed this. IMO anything smaller than a true T4with large A/R ratio, will generate excessive exhaust back pressure (exhaust pressure between heads and turbine inlet), greatly reducing efficiency and high HP potential. The turbine becomes a huge choke point if not sized properly, and the power will simply dive. Any time you see a dyno graph where TQ is lower than max HP (or if the two are even getting close), it is a good indicator that the turbine has reached its maximum flow limit.

Remember, all that air the compressor pushes out is mixed with fuel and ignited....all this has to go through the turbine housing.

Why does Firedan's have sooooo much more power?

I'm debating on selling my gtm TT kit and going with theirs and upping the boost just to see what it can do on a built motor...

Can wait a bit more and you will have an answer.
Nissan370 has a built motor and is doing break in now with the VSR kit and about to retune it for more boost. Link: stillen supercharger to vsr top mounted turbo

Why would a setup like this have any left over oil in the turbo. Shouldn't gravity drain it all back to the pan?

TopgunZ · 02-12-2014, 06:02 PM

Im not sure. Maybe it could have been coolant burning too since it is coolant and oil cooled. Or whatever doesn't drain out, whats left along the sides, just boils.

Bobby is putting this kit on for me next Monday at the shop. Already put the deposit down. I'll post the Dyne charts and vids here for you if you're still considering it.

Not a problem. Wish I'd posted yesterday as I was at the shop for about 5 hours getting my oil cooler reattached after my own new engine drop.

Does bobby know your alias on this site or do you want to pm me your name?
