Hey fellas just wondering how many guys are boosting L92 heads. On a 6.0 what kind of numbers are you guys seeing? I have L92's and 317's. Not sure which head to go with. Would like to get 600rwhp pretty easily. Do the L92's make a significant amount more? Thanks.

 

a side my truck, ill be boosting an LY6 with worked L92s in a week or two i hear they will be flowing pretty damn well i can give u back feed back till then

 

Great thank you.

 

I made 746 at the crank with 6lbs on 91 with more boost and fuel 850 out of a front feed 2.9 liter whipple dont have at the wheel #'s yet mine were done by west coast racing heads and they have a stage 2 port port job I feel like i am lacking bottom end but that could be better with a different cam or cam timing the up side it got top end like a ****, the higher the rpm the harder it pulls . I am running 373's in the rear and a 80e still have stock converter I autocross and road race this thing and have been reluctant to change the converete I am worried about loosing engine braking even though a converter would work wonders for the bottom end

 

Im just wondering if there is a large competetive advantage with the L92's vs. 317's. I know the runners are 260cc's vs. the 210cc's with the 317's. Just wondering If 600-700hp is easier to obtain with the L92's. With less boost that is. I mean 10psi on L92's vs. 10psi on 317's has to be a hp/tq difference.

 

I have ported L92s on mine...makes a **** ton of power with just a little boost. ~15lbs is about 800rwhp, 20 is around 1000.

 

Thats what i like to hear. I wonder how much less power i would make with smaller cubes than you.

 

Thats a loaded question, but add some more boost or spin it higher and youll be around the same.

 

Hell I've already spun it to 7600. LOLZZZZZ
