900+ Whp whats your commanded AFR ? turbo or SC ? pump gas + methanol or E85 ?
Any body running mid to high 11 AFR ?

I run 11.4ish 93 and meth. I'm 30lbs of boost. What boost you running

wesam

Woooww 30lbs ?!! How much it put down ?
I'm @ 18 psi

I"m at 907whp with 15psi d1sc and at WOT with 91 pump gas and dual meth the AFR is ~11.1 to 11.3-ish

94 and meth, 19.5 lbs boost. I run .78 lambda, or about 11.2. Used to run a little leaner with less boost, but I don't trust that every cylinder is the same, so I like it a bit richer, and safer.

Unreal

91+meth 10.3ish, 1100+rwhp
e54-e85 + meth 10.6-10.7 1100+rwhp

Offtopic but I remember you mentioning in some thread that you're tuning at street, not dyno. So how do you know your rwhp?

I don't like dynoing . I street tune. I have two meth pumps and running 4 -15 nozzles. 20* timing. So what power it's running I won't know. I have 50k on the motor drive it every day except when it snows. When I built my next engine and have it ready to install I'm going to dyno it. If it blows I have the other engine ready.

Don't check spark plugs at all?

helga203

No, every once in a while it pisses antifreeze from the heads. I have my rev limit somewhere in the 5k range to hold the boost around 26ish.

Wow that's a lot of jam for a d1sc on pump! Engine combo?

IIRC its an LME 427. Nice motor with the D1 spun max.

I run mine at .77 or so on gas and meth. 850whp

neverstop

motor is way overbuilt and full of fancy LME stuff, ported MAST 305 heads, expensive valves, custom cam, gas ported pistons, etc. I was originally planning on building >1,000whp setup but then got to 900whp and decided at this point I don't need more for a street car....haha

Unreal

Only assuming power numbers haven't gone down. Dynoed 1100+ 3+ years ago, with less boost, 91 octane/etc.

Last time it was on a dyno it made 1116rwhp on 9 degrees of timing 22psi, and 10.2 AFR. On 14 degrees it pegged dyno out. So thats why I just say 1100+. Ran side by side if not slightly pulled my friends recently dynoed 1170rwhp corvette, so lines up with that.
