just got my car back yesterday after getting tuned by Dan Millen at Livernois. here is my setup

402ci LS2 shortblock built by Canadian Performance
Compstar crank and rods
Wiseco -8cc Pistons
11.14-1 compression

Heads are Livernois stage 3 L92s

240/252 .650/.661 114+3 comp cam speced out by Patrick G

stock L76 intake
90mm throttle body, stock mass air meter
50lb injectors
1 3/4 hooker headers, TSP true duals

numbers were 505rwhp 474rwt

i happy as hell considering that this was done with 1 3/4 inch primaries, stock intake, mass air still on, no underdrive pulley or EWP. motor was built for a lot of spray too. this was through a 6 speed with a poor little 10 bolt.

im still waiting to get my graph back, probably monday, then ill post it up.

power i think peaked around 6300ish, seems like this cam should pull power a little higher, im happy that i hit the 500 mark with the setup it has right now

Wow! great numbers although that stock 10 bolt aint gonna last too long with 505hp goin through it!

nice torque!

thanks guys,

over the winter i want to swap over to 1 7/8 primaries, 2 inch ones are sweet but a little overkill for a little 402, probably do an underdrive pulley, go speed density and pray somebody comes out with an intake manifold.

9 inch is next on the list though

you probably have another 20 hp even with a 9 inch in the picture once you change the pulley and waterpump... plus the motor will gain some once it's got soem miles on it I'm sure.

Good pwr for sure.

how the hell are people doing more then this with stock heads i seen i guy do 522 with stock heads with cats??

i wonder the same thing. how are some guys making the power with out of the box heads?

JDP

iTrader: (21)

im guessing the intake is whats holding them back, the heads can only flow as much as the stock l76 intake will let them.

plus i think ill pick up a decent amount with larger headers

JL ws-6

iTrader: (50)

I am sure it will pick up with the bigger headers. I am running a 402 myself, and am probably going to get a set of the 2 inch primary kooks over the winter.

i want to go 2 inch, for the fact that ill be hosing the **** out of this motor, so ill probably go with those

Justin, great results, especially considering all the power mods you still have left to do.

Larger headers (big gains here)
Ported intake manifold (another biggie)
UD Pulley
Larger MAF or no MAF
Electric water pump
Shaft mounted rockers

The fact that you exceeded 500 rwhp so easily speaks volumes of how well the L92 heads work. How's the driveability of the car right now? Can't wait to hear about the power once you put the big shot of spray on it.

more compression

ya, i was happy as hell when i heard it made 505, and there i so much more to do. driveability is good, but dan millen had a hard time trying to tune these style injectors at idle, but other that that its good. pulls like a raped ape, idle sounds ****, and starts right up o problems evertime.

thanks for the cam Patrick

just have to pray my 10 bolt will last me untill i get a 9 inch in there, im going to do the rest of the mods before i spray it. but it will be there one day

I can also state Livernoi's dyno is pretty conservative, I was down there when a car drove straight to us from a run on another shops mustang dyno. It made 440 on that mustang dyno, it made 382 on their dynojet. Dan assured me that the dynojet is recalibrated very often (he said more often then any other shop he ever spoke with) so it had to be an issue w/ the other shop's mustang dyno. My point is that every body's dyno is different, alot of people that make unbeleiveable numbers are usually unable to back it up on other people's dyno's.

505 is about right for most stroker l92's that have come through @ Livernois (according to Dan) whether they spec'd them or another shop spec'd the parts. so far I think 520ish is the most they have seen, and surprisingly enough it was on a combo that had less compression the his, and a smaller cam. My point on this is its clear the l92 combo's are in their infancy, just like ls1 stuff was 5 or 6 years ago. There are still people coming up with new ls1 combo's that work, and its 10 years after the engine was released. Just imagine where l92 stuff will be in 9 more years

Hey bro, I haven't heard from you in a long time. I sent you a PM. CONGRATS on all the horsepower your new engine made. We didn't get to run last year, and I kept missing you at the 50's McDonalds. I still owe you a ride. By the sounds of the power you are making I can't wait to go for a ride. Actually a bit afraid to run you. Your new motor sounds like a beast. Don't worry about that 10 bolt, she'll last until you race from a dig. 474 rwtq is a lot of grunt. So get ahold of me, I got the itch to run bro.

Port that intake and see what she makes, should be a good bit of power.

ya, i talked the chad about a couple other l92 headed cars you guys had come through there and the highest i think was 516 or something like that, but i think he was running 1 7/8 inch headers, so i think my car should be right there if i had the same, im happy i didnt pull a mid 400 like some of the other setups ive seen, im glad i broke the 500 mark and still hve potential to make more power.

i just cant wait for somebody to come out with a damn intake for these heads, because i know these stock l76 intakes are holding these heads back.
