You will need to go 100% meth.

Man you’ll be hard pressed to be able to run full E. It’ll probably end around e40-50 with 100% meth.

I'm at e30 now. With the low side. I thought I'd be able to at least get 50% with the fuel lobe.

What the WHP mark normally for the mods you guys think?

It depends on who's tuning it but generally speaking you can't run much over 700rwhp. Running straight E85 is really tough on these motors. Meth and 100 octane are your friends.

Your ethanol content will be directly related to how much meth you run. The more meth you run the more load you take off your fuel system.

Most I've seen done by rpm was 850 whp / 897 wtq and cpr was 842 whp/ and I forget the wtq. I have close to what you have. My dyno pull was was no meth cause I still need to buy it. In 5th with sae correction factor netted 671 / 751 on pump 93.

I'd think with e50 and 100% methyou should see over 800 wheel

thats pretty impressive. It was around 660 whp. Only additional power adders really is the stage 3 cam, lower, and 5 inch intake.
and the pistons and rods for safety.

did you change out the crank bearings? The thrust bearing is the weak point.it goes before the rods.
I have 5" cordes, zr1 modified 100 soler TB, kong port job, 1 7/8 lt headers, 3" off road x, 13% lower, 2.3 upper, mti custom cam with 32% fuel lobe, jms fuel pump booster, and flex that I cant use lol

Curious why you went with new pistons and rods? The LT4 SBE seems solid to 1000 wheel. Just added insurance?

I have a stingray with a LT1. And yes I had 2 cracked pistons. So it was a good thing. I actually went with pistons and rods.

Oh I am sorry, I misunderstood. I thought you were building a LT4.
