Well I took it to the AWD dyno and got it dialed in for 9#s. It ended up making 491AWHP and 560AWTQ. This is a bone stock LQ9 with a Livernois turbo kit bolted on

 

some nice numbers, is that on the turbo that comes with the kit, a gt-37 i think, or is it the upgraded turbo

 

Daymn that's makin' some power now. Bet that's a blast to drive...

 

thats awesome man. i love the looks of that thing, and now its got some good power too

 

Very nice.

 

Those are damn good numbers.



I've never figured out why turbo set ups make HIGH numbers on the dyno compared to a S/C set up yet, they usually run very similar times at the track. Anybody care to explain that to me?

Same truck:
ie..6L @ 9 psi turbo makes 550hp/tq on dyno, runs 12.5 qtr.
6L @ 9 psi S/C makes 475hp/tq on dyno, runs 12.5 qtr.

 

maybe it has to do with the under the curve power a SC has compared to a turbo

 

i think it has more to due with the turbo lag...s/c are instant boost, where are the turbo has to spool with the rpm's. i think the turbo would perform better with a manuel tranny b/c of the clutch factor...just my un-professional opinion!

 

IMO, Turbos are more efficient and generate more power but on the track in a "street" vehicle form there is generally lag and is where the superchager (roots style) takes the advantage.

 

no it is a 72mm turbo
