I cant wait!!!!

 

So stock 6.2l vvt and all you were 550rwhp with the top mout and meth at about 10psi? Time for me to start planning, vvt delete boost cam, top mount, meth, real question is the fuel... What did you run, stock flex pump or duals or a stand alone second pump with e85?

 

Here's a different customers 6.2 feed back he texted me.

"Ok..so final specs on truck are forged pistons and rods, stock block and crank, stock heads, ls9 cam and ls3 springs, stock 6l80 with tuned, pure meth injection, trick stage 5 kit 10lbs boost, 619rwhph 3400 stall, stock injectors and fuel pump, zr1 map sensor and maf."

 

This is pretty close to my setup.... those are good numbers.


stock injectors though??? That doesn't seem right.

 

Im still running the stock flex pump. I'll see how far I can push it. But plans are to install the walbro 400 or a dual setup.

 

I am still on the stock pump also. Fuel pressure get's hit pretty hard from a WOT dig but AFR and IDC are spot on so I haven't been to worried yet.


I don't see how the stock flex fuel injectors can handle 600HP though...unless the METH really makes that huge of a difference

 

Not sure but flex fuel truck has to be able to move a huge amount more fuel then no flex fuel set ups.
Customers thinking the injectors are 54lb unit from factory.
Those engine are rated at ? 400 engine hp?
What's the fuel flow rate needed to feed that with e85?
I have no idea what the stockers are rated at never checked.
Also can't say how much meth they were using.
But he did tell me the fuel system still could go higher but they were happy with the numbers.

 

I'll be building the above combo next week with the exception that I have 60# inj. already . Now get cracking Rick and send me my parts.

 

Build thread please! I am looking at the exact same setup you've got listed. Your swapping pistons tho?

 

It will be a 6.0 from Thompson Motorsports. It has a stock crank, H beam Rods and Diamond Pistons. It will be topped with a set of stock LS3 Heads and I'm going to try the LS9 cam. Tons of guys say that its not ideal for turbo but its hard to argue with 600+rwhp on 10 psi from the above mentioned combo. I currently have a Trick Stage 3 kit with a 228/238 .571/.586 on a 117 in my truck. I dont know if I should keep it for the above combo or just use the LS9 cam.
