IM Not saying Meth is bad......Im just saying meth in only two cylinders is bad....

Run race gas people, water is/was not meant to but injected into an engine. Either build the engine to live up to more boost or go home with your water injected busted engine.

Did you care to read over my post? There are plenty of perfect scenarios for Water/Meth injection.

And if it's really that 'unsafe' than why have so many race teams/projects used it and why has our own military used it specifically to compensate for the power we needed out of turbo props!

Exactly. To me, those who dislike water injection are similar to the other group of people who despise nitrous applications too.

I find that most people who are against water/meth injection talk it down and then eventually move to it. Put it this way - I've only heard "Yeah well ... if I had water/meth too then I'd be just as fast..." ok - so get it. Then it'll be "well if I had nitrous too then..." ok - do it.

Those who can't do, teach. And those who can't teach, hate water injection.

Werd. I'll add that one of the first cars available with a turbo system actually came with an auxillary injection system from the factory. It was the olds jetfire which had a 215ci 10.25:1 comp turbo v8. And this was the early 60's. Buick was also seriously contemplating it for the turbo regal.

been running methanol on my 195,000miles engine 3000gt vr-4 on pump gas for several years now. on my 16Gs i put down 350 @ 15psi and 420 @ 17psi, last time i had the car out i was at 25psi and the car felt retarded fast. the compression is still perfect, to me methanol is one of the greatest things ever made. it unfortunate some people have issues with it, but i run it on both my vr-4 and DSM without problems. I tried messing with different mixtures but in the end for me the 100% VP M1 meth works the best. I will hopefully be pulling the Vr-4 apart soon to replace the valve stem seals and change some things up. I guess i will get to see what running meth for prolonged periods of time will do.

People also have issues with blowing up motors because they half-assed a turbo install. That doesn't mean boosting is unsafe. It just means not doing something correctly can be unsafe.

i think u pretty much hit the nail on the head there man. this is the case with anything that is car related and you only really get half the story anyways after the said motor has been blown up. Is someone gonna post that they blew their motor cause they neglected to check if they had meth and just ran that **** bone dry? offcourse not.

As mentioned on this thread early this motor blowing up had nothing to do with meth. vince simply posted a picture from my heads which at one point saw meth and wanted to let everyone know what he found. the car blew up from insane power levels on stock internals which were totally expected,car was tuned for c16 and 0 meth and i know i was pushing the limit , since its my personal car.

car did not see meth for about 2moths before the c16 tune and 3 months before it blew up since i went another direction and removed it from the car. the damage to the engine was the stupid cylinder 4 ringland that the 2.5 l subies suffer from at high hp levels

Come on dude, tell the truth. The car didnt realy 'blow' up you only wanted to tear her down and get new engine!!!

oh it blew up , just not bad, cracked piston ringland

mine is coming out now

I really have no problem with people running meth/water injection kits that are using it for safety, but let's be real here, damn near everyone using a meth/water kit is upping the boost and trying to get as much power as possible from it. Which, in short, is exactly the same thing as tuning for power on pump gas, only instead of your engine relying on your fuel pump and injectors to keep working, it is now relying on your fuel pump, injectors, meth pump, jets, atomization and even distribution through the intake manifold to survive. Most proffessional race teams use meth for safety and cooling, not for more power. Some more power maybe, but not a lot.

Race gas is still better for making power though.

[SoStock92]

It depends on how you define "relying". If you have a tune that runs a 400 whp setup on pump fuel, you may be relying on 93.0 octane fuel. If you get 92 octane in the mix somehow, you may have issues too. If you tune for 93 octane + 600 cc/min of evenly distributed 50/50 mixture water meth, and you're making 500 whp on that, if you get the mixture of water/meth off you may have an issue. Point is - 99.99% of the people with Evos, SRTs, Stis, are adding water meth without actually knowing what they're doing and then turning the boost up. Meth injection doesn't = more boost. It equals more power safely. They should adjust their timing, not their boost (and consequently IATs..) but thats just what people think they can do. Obviously if their tune isn't set up to run 25 psi, but they crank it up anyway, who knows what'll happen.

The subaru motors, in my mind, require multi point injection or none at all. Same with porsche, same with old VW. Its just the nature of that design. The guys having issues with water meth are the huge population of SRT4's and Evos, and such that really do not know wtf they're doing to begin with.

I am friends with a guy up in CT who is running over 650 sae hp on a 3.2L BMW motor (stock internals) with a low CR headgasket on 28's. He's moving to 2871s now and trying to 700 -but this is on pump fuel w/ methanol injection and yeah hes definitely only on one walbro 255, so he's relying on the methanol. But he has an aquamist system with flow control and dual nozzles so it should be about as safe as a fuel system and he doesn't care if he breaks something (record on that motor so far is 704 rwhp before it bent the rods). So yeah, there's degrees of "relying on".

Well, you have proven to know what you are talking about here. cause the Suby intake (engine design) is def not a good setup for a single nozzel injection system, and thus make sure to get good atomization and NOT tuning toward max tune (timing and boost). Seek a good tuner IMO! Ray fits those shoes.
