Let's hear your l92/ls3 combos and rwhp numbers
I wanted to see how much power these heads are making with specific combos.
I have a 415 l92 stroker
caliies forged crank and rods
mahle 11.3:1 scr
cam specs 238/242 605/615 113lsa
1 3/4 headers with stock ti exhaust
stock crank pulley
When the engine was dynoed at 400miles with conventional oil and stock h pipe it made 490rwhp and 475rwtq. If i find my graph i will post it but it falls off pretty hard after 5800rpms. I also have my doubts about the company that tuned it which are no longer in the business of modifying cars.

Even if it was the ls1 intake it shouldn't fall on its face at 5800,gradually fall maybe.
I think its pretty solid numbers for the combo?
hey GA95DCMSS did u ever try to see if the truck intake fitted under the hood?

I run a much smaller and different cam than you run and make more power with a 4.005 bore. I make 380RWT at 2200 and 400RWT from 3k up and my wife could drive the car it runs so smoothly. I ran a 234-240 112 +0 XE-R and made 510/468 but my current cam is stronger in the middle and makes bigger numbers with the cutouts open and not running through the Ti's. Numbers are very repeatable on the stingiest dyno in the east.....Damn you Ed.

jesel's everywhere-
soild 250 region on 110
cast intake-light porting-
single stage n20 system between 150-250 only-
we are looking for a min on 550 rwhp n/a as my 346 on a 175 shot made that
will be very happy with a 1.3-1.5 hp per cube at the tyres n/a-
and use the 150 of n20 as a base line and move on-
will be ready in a month or so-just waiting on some more parts-and the usal machine shop stuff-
Hope that helps-

l76 intake. I think my combo is lacking power. Might be the headers, but more than that i am worried that somewhere after i dynoed my car i am missing some major power. Because my trap speeds are very low. They seem to go up as my times get faster, but are very low for the power it was making. 124mph was my best when i ran 11.7 bogging and spinning. Also since then i chunked the stock air bridge because i was told it was costing me power. Bought a wcc air bridge. Also the times were in humid mid 80's weather but i am at a sea level track. Dont know but it just seems like it is not where it needs to be. I raced a friend of mine with an 02 zo6 with some bolt ons and around 380rwhp and i gave him a half car jump in 2nd and pulled about 3.5-4 cars until 5th where i leave him hard.

I will be the first to say calculate the DA regardless if your track is at sea level or not. Bad air can easily cost you 2~3mph or more.

Please keep us posted on your results. I am curious about a L92 solid roller setup.

I'll play.
Motor is a stock short 6.0 with upgraded rod bolts and oil pump. Stock L92 heads milled .030 for 10.25:1, stock rockers. Cam is 226/238 .607/.610 113+3. The tune was pretty fat even when I left the dyno and I have no idea what the timing is (mail order tune). The intake is a sheet metal unit. Power at this point is off what it should be. Hopefully timing and fuel adjustments can bump it up, but I don't think it's going to be enough.
The car is kind of a bitch to drive, the aluminum flywheel makes low speed take offs tricky. Myself and my wife are the only ones who have gotten in and not stalled it right off the bat.

^ What transmission is on the car? You aren't reving near high enough to take advantage of the intake you are running. Your numbers are pretty low even considering the tune is a bit fubar'ed.

I have an L92 Cartek 441.
stock ported intake
13:1 c/r
Hydraulic roller
non lock up th350, 8" converter, Moser 12 bolt, 3:73's, 30" tires
Car dynoed 536 rwhp, 636 rwtq
Kind of hard to see where she starts to tail off on the dyno with the non lock up trans but I can tell you from track testing that she pulls strong past 6700+. Car ET's better and MPH'rs better the higher I shift it. (shift light is set at 6500 right now)
Solid roller set up aside I really don't think the stock intake is hurting flow on the L92's, even on a motor with my displacement. Heads flowed 330+ cfm through the intake and at least for my set up is not lacking anywhere through the rpm band.
I'm curious to see a solid roller set up for the L92's as well since that would be my next step.

The graph is a little bit screwed there. The end of the run was 7000, not 6650 and it starts at 3000, not 3850. I only stopped because the short is stock. I'm not sure where to go on a cam at this point.
