Lq9 with L92 setup what do you think? VIDEO IS DOWN AT THE BOTTOM THE CAR IS UP
My setup is almost done and i was wondering what do you think it will do ? Ive spent so much dang money into it I hope it runs good i have a full weight camaro. What numbers do you think itll put out also what times... i also have suspension in my sig if that helps thanks!+-
lq9
L92 heads
L76 intake
hooker longtubes
tsp duals
Built TH350 TCI 4000 stall
226/238 600/600 116lsa
85mm maf
fast 90mm tb
fast fuel rails
fast 36# injectors
asp u/d and overdrive pullies
and maybe a 75-100 dry shot

Should run damn good on or off the bottle. Through a stalled auto, I'd say it should put down somewhere in the high 400's at the wheels on motor and mid to high 500's on spray, depending on how much you decide to go with. Also, quick question. You have any PTV clearance issues with that cam and the flat top LQ9 pistons with the L92 heads?

I hear that Lloyd is good to do business with. I heard more about him in the LTX world than the LSX world though. I have been looking into going custom grind too, even though the TSP Torquer V3 is very tempting. Hell, if you don't have any PTV issues, I may just step up to LS2/LQ9 pistons to bump compression up for a little more power. I just figured the stock LQ4 pistons would help me stay away from PTV problems.

actually its a "lq4" block but i bough lq9 rods and pistons and threw them in it! lol I wouldnt do any ordinary cam in the setup the heads dont work well with all of them so your probably better off getting one for your specs i paid about the same for a typical cam like i said pm or email lloyd and hell take care of you!

That would mean that he's losing almost 200hp through the drivetrain. You've got to remember that an LQ9, with that cam and L92 heads, should be making somehwere in the area of 600 crank hp. In a Car Craft article, an LQ4, with a somewhat small cam (228/230 .56x/.56x ???) and L92 heads made 550 crank hp. With the added compression of the flat tops, and the bigger cam, there's no reason he shouldn't make close to 600 crank hp, which would be somewhere in the high 400's at the wheels, even through a stalled auto.

Stalled autos usually equate to a 25% drivetrain loss. So lets say his car makes 580 flywheel. Thats 435 Rear wheel horsepower. But what do the numbers matter anyways. The car should rip at the track where it counts.
Just a little comparison though. I have a 6.0 with flatops and milled WCCH L92's and a slightly bigger cam. Through a 6speed (on a nitrous tune) on the motor my car made 478rwhp. This same engine through a 4k stalled auto on a Good motor tune made 420rwhp through a LOCKED converter. Unlocked it made 380rwhp. This is the same motor in all these runs on comparable days/temp
Going even more into detal. The same motor on a 150 shot through the 6speed made 643rwhp. Now the same motor on a 150 shot in my stalled auto made 530......
So im not just blabbing out numbers i am speaking from experiance with this type of setup going from 6speed to a stalled auto.

Dam it. Should have not sold my LQ9 
I knew i made a mistake. Would there be any reloctor wheel issues. An LQ9 is a 24x reluctor right and its a 99 SS. Should be the same I guess. The 58x reluctor are the 6.2L right? Not sure if any of this is correct but that was why i sold it but didnt not know this or that you could buy an adapter if you need one.

curious to see what that cam does I have a similar one going into my PRC LS3 headed lq4 67cc chambers
cam is 227/235 .614/.621 113+4 0.040" gaskets and flycutting.
ls3 intake/ls7 injectors 92mm tb static comp is 10.3:1 DCR is 8.1:1
are you going to run GM MLS gaskets?
I'll have a stalled 4l80E behind it and a 9 inch
