just make sure the meth does not take a crap on you. Happened to me on a built a motor lucky for me i stopped quickly.I would imagine on stock cast pistons it would have taken the motor out.

I just dont trust meth kits.

That is only the case if the tune is "Meth Dependent."

I am becoming educated on Meth kits. Trusting LMR to put in the kit properly and the safety put into the tune.

I thought i read ECS made 754 on Meth and cam. I would say that is 100% dependent. That is what worries me.

So it is dependent on meth to make 750 but when meth quits it makes 600. That isn't a safety issue, just a power issue.

maybe I am confused , LMR is saying only if its meth dependent? They are only tuning it for cooling affect , keep IATs at bay.

How can a car react fast enough in a middle of a WOT run (which happened to me) and meth stops working ? there has to be that 1 sec where its too much power for pistons.

If someone runs that low after ignoring the low fluid level, they deserve it.

If it's a nozzle that goes bad, the timing/maps just back down. It should act like you're losing fuel and just back down and lose power.

Am I wrong here?

Mine took a dump in the middle of a 1/4 mile pass, not once , twice ! lol

In vegas it hits 118* in summer and that causes these meth kits to seize.

Hadn't considered that - extremes do certainly cause issues.

Twice, though? Who'd you **** off?

lol. Yep 2 different months. that was my 02 z06 twin turbo. Sold it and bought a 06 zo6 with only bolt on Si A&A s/c. it made 678/600 on 91 with 1 can of Torco.It was slighly slower than the 02 but no worries on meth going out.


I am having a S/c installed next week 91 plus 1 can of torcO.I think it will make 600. Hoping when the Z06 comes out we can get the fuel pump and injectors , swap it out for E85 tune and zero worries making 700whp all day.

ran E85 on my Daily GTR for 4 years making 850whp 9.5@151 in vegas during 101* DA 5000.

You posted so thought you’d know.

It’s barely a high school level ratio calculation. Methanol is usually rated 113-116.

Octane3 = (volume1 * octane1) + (volume2 * octane2) / (volume1 + volume2). Octane3 is effective or blended octane.

So simple answer is, more methanol would have to be spayed than gasoline, allot more LOL.

Repeating what I was told about the effective octane with regard to timing advance from a very well known person here. I didn't mean true combined octane (R+M/2) for Christ sake - that was with respect to effective octane with regard to timing. Actually, he said it was quite a bit more than than, but I digress.

I've explained true vs effective octane levels in detail when people have asked about Torco, etc. so I know the math behind it when it comes to fuel in the tank...

But I won't argue - if it's wrong, it's wrong, and it's my fault for either repeating it, or not making it clear.


Edit: Removed the posts. If the person that explained it to me the other day would like to post the info here, I'm sure it would clear things up. Otherwise, disregard.

There’s a ton of bad info floating around about meth injection, this thread qualifies…

That's a general statement, not necessarily pointed towards you. Just because it's posted on a forum does not make it true.

Well, I'll be taking down the post(s), then, and chalking it up to conjecture. My lengthy discussion on Torco is dead-on, while I used someone else's words here - most likely incorrectly.

I'll stick to helping people with my 'limited' skill set. Been taking a lot of crap today, might be time for a small vacation from the forums.

You'll want to edit your posts to remove my misinformation. I've just had a bad day overall, Skunk, so it's not just you.

A lot of good discussion back and forth regarding meth injection. I thought of a conservative tune, meth with some vp 109 in the tank for safety in high heat and altitude. Am I wrong?
