This should be the Highest Whp for a stock bottom end LS7 as far as I know. Here is the mod list. Fuel is E85.

LG Motorsports G7XX Camshaft/ LG Cam kit
Wcch stage 2 Milled .130* 13:8.1 Compression
Stock LS7 Manifolds
160* thermostat

Fuel Lab adjustable FPR
Twin AEM 380lph in line fuel pumps pulling from a fuel cell
TurboBay Performance Billet S480 T6 1.58AR
Car was tuned by Darin Dichara@DoubleDtuning
Setup was built by Matthew Coleman@SpeedZone Kissimmee FL

6psi of boost and 10* timing

Prior numbers were 623/545 when the car was N/A

6psi from the TB Performance S480 netted 837/741

Please tell me he made a jig for the kit?

What kind of fuel are you running?

C6 Curtis

E85 for fuel I also added more pics.

I had the same head porting and milling done to mine when it was N/A. Can't believe someone is throwing boost at it too! Interesting build for sure

Edit: nice STD corrected numbers too btw. That still puts the car at the 800whp mark approx.

Get the bottom end built and run twins!

In for more pics of the setup.

Thanks man and for putting up with my questions when I was trying to hit 600+ N/A lol. I just wanted to try something different. Pretty much took an all motor setup and slapped a turbo on it.

I'm definitely going to build a motor in a couple months. Probably run 2 s480's or go with a single 106 or 118mm

that is awesome.

Can make 2k on a 106 . Sounds similar to my z build right now. 2 promod 88s on that thing

I like your build. Hopefully it stays together. Nothing like a high compression boosted car.

Your car sounds wicked on the dyno! Nice to see someone pushing the stock bottom end into the 800rwhp range. Good choice of fuel too. I run E-85 on my nitrous setup. Hard to detonate, it's a nice buffer to have.

C6 Curtis

+1 it is SUPER responsive. Still has a lot down low.

Thanks. Yea e85 was definitely a must with this set up. It actually could've been pushed more at the same boost but we wanted it to last.

T6 96 turbine? Curious how did you do the crossover ? Stock headers?

Congrats man love the setup and hope the LS7 Stays strong

C6 Curtis

Yes, T6 96mm turbine wheel 1.58 AR for the housing, you can get the 1.58 from liljon or work turbochargers. The crossovers are Vbanded from the stock LS7 manifolds. The LS7 exhaust manifolds were cut right before the cats and Vbanded. I used 3 inch crossovers from each side, worked fine for me and it's not laggy at all. It's been running flawless so far, I'm going to take it to the track pretty soon, It's not going to e.t for crap until i get a good tire on it but I'm hoping for a 150+ trap.

Got any pics from under the car? Would be nice to see the pipe runs. Do you think you would be able to tuck the DP back under the car?

C6 Curtis

I sure do.
I'm sure if smaller piping is used on the crossover you can have it tucked back under. Like 2.5 inch or 2.25 crossover would work fine for that. For me it was either dump up or down.

This is my new favorite build. WICKED clean, and badass numbers. Time to build a bottom end and crank up da boost!!

C6 Curtis

Thanks man, I definitely have big plans for her later down the road. I might turn it up some more before I retire this block and put a new one in.
