you are about to!!!!


cage is getting welded in right now, will be about two weeks till i get it back then i have a th400 going in and headed to the track!! finally i can turn the boost up over 13 psi without frying a clutch!!!

 

On another note, will 20Gs get you there? 20G compressors max flow rate is 48 lb/min of air. So you are looking at roughly 960 Crank HP of air assuming decent comrepssor efficiency and some good flowing cams and heads. At that max flow rate the 20gs are only at 68% efficiency. You may need a higher flowing compressor wheel then that to make 800 all day..

 

nice happy talking....

Mia,

I am not sure about everyone else, but I know a few of us have looked at the same air flow #'s that you have. We decided to have custom turbo's made to try and get maximum efficiency & volume for the longest period possible.

I would hazard to guess those hitting above 700 whp are using some version of 18 & 20g housings with different compressor wheels.

 

Thats what I figured...I know what Sharif is running...and its not a 20G compressor wheel...

 

Mia and Bam are both right. The basic Greddy turbo will probably max out in the 600-700whp range, depending on your dyno. After that, an upgraded setup woudl be needed for maximum efficiency. I am running a TD06 60 trim setup, which is basically like having two standard TN single turbos mounted to my engine. 800whp-900whp of air..easily.

 

Damn Sharif, great minds all think alike. LOL, seriously I am not even trying to say I know a 1/4 as much as you guys do about these cars. Just done as much research as I could, talked to a bunch of you smart guys and agreed with the recommendations a couple of shops gave me.
It sounds like we’re running the same setup: TD06 exhaust with 60 trim compression wheel and using Garrett's ceramic ball bearing cartridge.

Question: Are you upgrading your IC..? I think that is the next thing on my list as I am pretty sure that amount of power exceeds their cooling recommendation. I just don't want to get a new IC until I have run for a while and seen if the temps justify it.

 

The massive Greddy FMIC should be fine at 800whp+. I have always been impressed with its cooling efficiency. Even at 16psi of pressure, air inlet temps are only a few degrees above ambient.
