[19 2SS]

currently running a 2.9 whipple, big gulp intake, headers, 103mm tb, full borla exhaust, and my current fuel upgrades include a lt4 hpfp and dsx low side at 600whp.

My next step is going to be heads\cam with forged pistons\rods, injectors, and debating on meth to push it to around 850-900whp. is anyone running meth on a mainly street car that gets driven a lot? It'll be going to RPM in delaware getting their trunk meth kit if I decide to do so. so if anyone is running their kit specifically that would be even better. any additional maintenance that comes with the meth kit that you'd like to share will be appreciated too

I’d suggest E85 if your fuel system will allow. Even E40 is a big benefit and would likely eliminate your need for meth. I do not use any meth for what it’s worth.

If you really feel you need to go with meth, I’d just use it for cooling and octane enhancement, not fueling… Meth distribution in a typical setup is far from optimal and usually leads to a cylinder running lean (unless you do a full on direct port setup). Be prepared to replace or rebuild the meth pump every year or two.

The closest e85 near me is ~40 mins so unless that changes I’ll never be running e85, it’s just not worth it to me. So I’ll be running pump 93. But yeah my intent of adding meth was to get more fueling and staying on 93. Even with forged pistons and rods meth would be a bad idea to use for fuel? How far do you think I could push the car on 93 without meth with proper fueling?

Pump 93 is swill on a high compression and boosted engine. That’s all there is to it. 93 alone is good for about low to low/mid 800’s to the wheel assuming you are lowering your static compression ratio with your new pistons. FYI even a blend of only E50 at that power level gained me 90 WHP over 93 alone…

My closest E station is 40 minutes away as well, so I just fill up a bunch of jugs a few times a year. You could also have a drum shipped to your house once or twice a year.

Again, unless you spring for a direct port meth system (and for that cost you could add port injection…) the distribution is not terribly even. Sure, forged pistons and rods buy you a much bigger safety margin vs stock bottom end, but it’s not invincible. And the instant that meth pump (glorified fertilizer pump) dies, you’ll be lean and then poof…

If you’re lucky and all goes well I’m sure you could do well over 900 WHP on 93/meth (a pretty good amount of meth most likely). There are some guys who say they’ve never had a problem with meth…but they're definitely in the minority.

Skip meth. Thats a recipe for disaster if you run out or the pump fails during a pull. I'd always rather mix E and 91/93 vs running meth. No thanks.

[Kerry]

Yes skip the meth,,,,,,,,,,,,,,,,,lol I am running 50 gallons per hour for about 65000 miles now and making at a minim of 744 on 93. Since that dyno session im running I would say 800. I like the idea of running so much that if the system fails it will nose over from being so lean.
I think im their but its never failed. I did take extra steps to make sure, all connections including fuse is soldered. Prometh pump. seems to last. If a pump fails its usaly a leak that u see in the floor, could be a problem if pump is in trunk i guess. I know alky control has a new pump now that last a lot longer.

RPM does a ton of those systems, must be something to it so does Pray. With a pd blower I would think the cylinder dist would be acceptable. My plugs all look very even and I monitor both right and left bank afr. less than .2 or .3 difference at any rpm.

P.S. I would never run meth into the lt1 stock intake manifold. U will get from .5 to 1 afr difference in right to left bank. May be a very small amount like a 5 gallon but at that point its just not even worth it.

The very same thing can happen to the stock system. Injectors are know to fail. stock pumps. Just saying

The difference is that the car knows about it and would go into limp mode in a ms vs it having no idea its aux fuel source has just disappeared and the car went lean with no reason. And by the time the car sees the lean condition, you have already left your guts on the track.

Thats the difference.

Maybe. What ever fails hope its enough that its obvious. Like a fuel pump. Its gonna laydown, get weak. dead injector ur gonna know. Will it hurt that cylinder. Not if its dead. Thats why i like running a lot of meth. If it quits the car is go very weak. U will feel it for sure.


Cleetus run his vet out of meth a few times but then over 860 wheel on a stock lt1 with a procharger. Thats about 1000 crank broke a bunch of ring lands and finaly a rod. Was it the meth or the hp on a stock lt1. anyway its something to watch for sure but it allows power. Fran at RPM says they have seen even stock lt1 break ring lands. They should know.

Its not running out of fuel that hurts the motor, Its that just lean enough that it keeps running, Like an injector thats half stopped up.

The 4stroke engine is much more resistant to lean condition. a 2 stroke forget about it. Itll size by sneezing to lean lol.

When i got my procharger with their tune, their were times it would stay 14.7 all the way to red line at 6.5 pounds of boost. How many times did it do that before I got a gauge. Dont even know. Was that good, o helloo no. Did it hurt it . Pretty sure it did not. Pretty sure I got a tune lol

Any way everything has its risk. and that risk goes way up when u mod. Its not if it breaks but when.

What happens when u let off the gas. All fuel is turned off. It is not completely instant. but very close. Does that hurt it?

Is it better to make the power with out meth. YES. Is it as cheap, o hello no lol. In my case if it breaks Ill fix it, I dont rely on someone else to do the work. If i had to pay some one i would go about it differently probly.

Dont get it twisted I do appreciate all input. Im just sharing my experience.

Meth injection can make 50 all by its self. The e on top of that still more. E makes power because of the oxgen it releases on combustion. Meth releases more. And nitro even more. 3 best fuels on the planet. well nos.

making 744 on a stock motor i think is pretty good and because of the fuel im using. I think, anyway. at 13 pds at 6500.

Not to be a dick here but I've seen the data the car can see with logging HP Tuners. And what you are saying is all maybe this maybe that. If you were running that lean, the car would start seeing knock and pulling timing. It would do what its supposed to do assuming your tooner didnt turn down the knock sensors for that oh so lean is mean tune up.

But in all seriousness running meth for power is a mistake. If you are planning on the meth being there to run more timing, then you are asking for a melt down. If you are running a bit of meth JUST for cooling, not asking more of it over your base fuel, then you are doing it right.

But the car is not going to see or know what the meth controller is doing. Not a factory PCM. Now racecars running hollys or some other aftermarket computers might have the ability to watch meth controllers (I dont know), but that would be the only way I'd rely on meth for power.

The car only sees what it can see and will react to changing conditions based on the sensors it monitors. And the meth controller, pump and fluid level is a completely invisible system that it doesnt know about. If you are relying on that system for power, you are rolling the dice hoping the pump doesnt die or the fluid level is ok. Who knows what could happen.

And sure you could have a bad 02, or plug or coil or injector or maf or whatever, but as I said the car can see and read all those metrics in real time and will do everything it can within the parameters its allowed, to prevent knock and mechanical failure. This is not something you can say about meth and its components. Meth is a wildcard that shouldnt be used for power, but only for additional cooling. Thats it. And for most, just skip the meth and run e30/e40/e50/e60 or whatever mix your fuel system can handle. At that point if you need more, then do it right with the correct fuel system components.

Made it over 60000 miles now. Iv had a frailer of the engine for sure. it was not from meth. Stock rods over 1000 hp. But you dont understand some fundamental basic's. If the car runs out of fuel it will lay over. If your stupid enough to keep ur foot in it with an obvious loss of power then u get what u gave.

It wont hurt it if u let off. And u can bet I raise timing with meth. U can bet I totally rely on it for fueling. Have for a long time. But I think u should keep doing what u do for fuel.

How much have u spent on the fuel system? And thats fine.

Im very happy with my power level and how it makes it. Im about 820 wheel now. Traction limit with the nittos for me anyway. I dont want to depend of finding e. I like to go on trips where I may not can find e. I definitely need the octane. So meth to the rescue.

How bout useing it to get a plane off the ground because of the boost in power. What if the system quits before the end of the runway and u can't get off the ground. I would think that would be worse lol. It all started for that reason.

Quote But in all seriousness running meth for power is a mistake. end quote. Yes it is for you!!

A bunch of people who build cars for a living would disagree, including me lol.

Like you said with RPM, they use this meth kit on all their high hp builds and I was speaking with them over email and they said they haven’t had any meth failures in 15 years of doing it, I’m wondering if they do something differently than the other meth kits out there. I just don’t see how one of the biggest 6gen camaro shops use it on all their builds if it is so prone to failure
