lol i knew that was coming..

i looked at the snow kit but is it 100% alky compatible? from what i been reading seems 100% is more effective and way more consistent unless you mix you own 50/50 mix perfect every time.? i just like as few variables as possible

100% M3 or M5 meth, there are plenty of meth heads with out an issue, trust me. The Snow people dislike meth, because they have a lot of systems out there. When you use meth on their kits, the o-rings fail and they will leak.

Alky control is the only way to go, but the snow system with Stainless braid lines is VERY simple to use.

The Alky control kit is very tune-able, tune able to the point where you can activate it with the car not running.

As far as a Cam, yes. PM me the specs and I can have one ground with out an issue.

I see zero issues with 12.5:1 on an intercooled E85 setup making 800rwhp.

Im running 11.3 :1 compression with E85 on my LT1. Its running a carburetor with no intercooler.

I ran it hard all last summer and it has never given me any issues on 7 lbs.

Too many variables to know how much boost it would take to make 800rwhp... My guess would be ~13-14psi depending on cam and how aggressive of a tune-up.

no, i was asking how many LBs you were running with that compression ratio.

I am cranking mine up when warmer weather hits, and i was just curious.

yea i have no set goals on "psi of boost" im just gonna up it till i hit my mark or it starts getting sketchy lol. i dont think 800hp is to far of a reach.but i guess we will see. My ram air is coming out of the garage this week and in goes the muskrat.

And im glad to see some people finally coming out with higher then norm compression/e85 and boost and it holding up fine

Comparing boost level's vs parts between two separate motors isn't really apples to apples. I've never ran more than 20-21psi on this last setup. My heads flow upper 370's and a custom cam. My motor breaths rather well without boost

My weak link was the pistons. Broke one each time I hinted at ~1100rwhp. I tried out the Mahle power pack to see how far we could push a budget piston/ring package as we have several other boosted ls street cars. This year I'll have some good 2018 pistons in it.

408" iron block, ETP ls7 heads, 1/2" studs, Speed Inc hyd roller cam, ~11.75:1 compression, a2a ic, been run on E85 for a few years and C16 for a couple of days. I like the E85. Going for ~12:1 with the new pistons. My main concern is the cylinder pressures with these damn 4 bolt motors and lifting the heads. I've yet to push an ounce of water on this motor though.

Yes please do. im not sure how long till your car is done, but id like to see if it hits and holds 1k with 11:1.

I got most of the body work done to the mustang tonight, did some race crafters weld in dzues rails and needed to re-straighten the fenders. so this weekend is looking like mock up time for the twins and probably have it up and running in two weeks or so. then off to paint.
