Finally got the SS to the dyno for some numbers :)

Very nice, I would personally mix your meth with water. On the stock block you want the cooling aspect more than the octane benefits to keep things healthy. Being that you're only at 14 deg of timing you def don't really need 100% meth. My setup starts spraying at 6psi so very close to where you're at.
Well my iats drop a bunch when it comes on. Like 40 or so degrees I think I remember. My iat could get much lower I don't think. they are usually only 10 degrees above outside air temps anyway. Guess the intercooler does its job lol. And I know I don't need 100% but with the added octane plus the cooling it cant hurt..

I hear ya man but that IAT temp is being taken from the intake though correct? I'm talking more for the cooling of the combustion chambers/cylinders. When you run 100% methanol most of that gets burned up in the combustion process and you lose the cooling advantage in the cylinders.
is going in and 20+psi. You can hear it on the video when the rollers are catching up to the tires around 5500 to 6000 rpms. Also why the Dyno graph shows a lutch of more HP at that last segment of the graph.
Belt dressing works wonders on those big 48" drums
. Gotta love HP ! Makes sense, I might make it back down there before the end of the season to see if I can do a few more pulls and some more tuning with some race gas

Very nice!
I personally prefer 100% VP M1 for my customers spraying methanol. I'll be spraying 2 nozzles on my car one pre compressor one post compressor. 20gph nozzles and I might have some bigger ones in the works.

Thanks Martin! Do you recommend 100% meth even on a stock block at this power/boost level? It's a pretty common debate but i've always been told you needed the water for the cooling aspects in the combustion chambers.
As we speak i'm currently on the search for an iron 6.0 to start building this winter. I'd really like to have it mostly done and there as a backup since I know i'm pushing the current stocker pretty hard

Verdad Gallardo I always recommend 100% methanol on stock blocks/bottom ends. I feel you need all the octane you can get for detonation resistance.
These motors at this level cannot tolerate detonation. They will pop ring lands left and right from detonation at this power level.
I feel that if you cool the charge down and get rid of octane with water, you're still going to hit the limits of pump gas octane sooner or later even if your IAT's are cooler or combustion cylinder temperatures are cooler.
Did I mention I like octane?

Martin what do you think about the corrosion aspect of meth. I think it is like 20 or 30% water drops the corrosive aspects of meth by a huge percentage in addition to adding some cooling from the water. Jist what I always did. We would make a 75/25 meth to water mix.

The octane is very important but in my head I just can't get past believing I need the water to keep the combustions temps down. My current meth/water mixture is probably closer to 60/40. I really just wish we had e85 at the pump around here and I'd be all over it but sadly there isn't a station closer than a couple hours from me.
My engine just turned 50k miles earlier this summer but i've had it at this power level for probably about 5k miles or so over the past couple seasons. It's a fair weather car only so when I do pull it out of the garage its usually to go play with it pretty hard
mrstepheneades - Do you have the rear ports on your head open for coolant flow?

Ask Mighty Mouse why he runs 100% methanol. I wonder why the cars that run on methanol don't mix water with it. 
Water doesn't burn. It quenches combustion. It literally is putting the flame front out to cool the combustion temperatures. Put a better intercooler on it and run as much octane as you possibly can afford.
This is the way the heads up guys that are making 3000rwhp+ do it. A2W intercoolers with as much capacity as possible and the highest octane fuel they can afford.
Kind of like Nasa innovation and product testing eventually trickles down to us in civilian world? I feel the same way about ODR/Outlaw 10.5/X275 cars and their innovation and product testing trickling down to the enthusiast in the same form.
My old turbo street car had almost 5 years of being boosted and 20,000+ miles on it. 100% methanol in the reservoir.
The E85 you're wishing you could get a hold of is pretty much a 87 octane gasoline watered down version of methanol. Ethanol doesn't have quite the octane or cooling capabilities of methanol, but it's close.

BTW, I tried using many different percentages of water with my old turbo street car.
I'm not saying water doesn't work, because it does. I just prefer 100% methanol.
Again great numbers!

What ar is your 7875? I have a buddy who is doing a turbo build in his 78 280Z with a T56 and he was interested in my turbo until I told him it was a 1.15 ar. How's it spool on the street?
