No not a jab, just would look alot better with a trap at your weight to back it
All you see on tech is people say they dyno this and dyno that..... yet then you see supposed 900+whp cars trap 140

I guess so. I kinda took me making the number as validating others getting similar results. I will hit the track though.

Long story short I wasted over 3,000 in turbos, countless track passes lots of fuel. And lots of time. All because of having the wrong turbine. My engine is a 365 and the 1st turbo was a borg warner 80mm. The turbine was t4 83mm and a 1.10 ar. Then I bought another 80mm borg but this time I had a 87mm and also a t4 and 1.25 ar. At 11 lbs boost I had 14 psi back pressure. I didn not get a chance to mesure backpressure at 25psi but you could feal the car nose over. The new turbo I'm going with I spent ALO5 of time searching for turbine maps. And man what a chore that was. But I ended up having one of the 1st gt5018 turbos built by reed at work turbo. 98mm uhp turbine wheel in a open .96 ar

Thanks for the informative thread Mr.Jim!
After reading you post.........
"big compressor wheels and tiny turbines seem to be all the rage these days."
What's up with all the rage thes days with Anti-surge/Ported compressor covers that people are accepting on all these builds? Don't they reduce the size of the efficiency islands and really only move the surge limit in the 3-4 BAR areas where almost no LS engines operate?
