Methanol Injection

[orangefox]

Anyone running methanol injection in their cars, especially an 03-04 Cobra. Just wondering what you thought about it!

I don't think many if any, have gotten any great gains from it.

Then they don't know what the hell they are doing.

No Cobra here....but I have been running alcohol injection on my GN for about 6 years now. I have had good luck with it -- as in I've been running 20 lbs of boost on 92-93 octane pump gas, have 185,000 miles on my engine, and I haven't driven over my crankshaft -- yet! I'm still on the original head gaskets, even! <as he looks around for some wood to knock on....> I have never been consistent with it at the track, however. Sometimes & get it tuned right, sometimes I go pig-rich. Mine is an original SMC non-progressive type. A more modern, progressive system would be easier to tune. Anything else you want to know? Just ask -- I'd be happy to tell you what I've learned.

Badcobra was if memory serves, Worked awesome. I don't want to speak for him but, i think he was switching back and forth from that to No2. But he would be able to answer that.

Done right, impressive gains are possible. In WWII, many turbo and/or blown aircraft engines used water/methanol injection or N2O for 'War Emergency power'. They had excellent results with both techniques.

There are guys in the national GN club that are running mid-11s with stock engines @ 25 lbs of boost on 92 octane pump gas by running alky injection & a nice front-mount intercooler.

With 160,000 miles on my little Buick 3.8L V6, I dynoed ~400 @ the wheels with ~485 lbs of torque on an inertia dyno. Torque averaged just over 400 lbs for the whole pull, while HP averaged around 340 or so. That was in overdrive @ 23 lbs of boost on AvGas with a little alcohol on the side. Not too bad for a then 17-year-old stock V-6 with a few minor bolt-ons, running through a 4-speed auto....

In a similar state of tune, I ran a best 1/4-mile of 12.76 @ 106 on a 2.1 sec 60-ft. I had BFG 275-50-15s out back, and still couldn't get enough traction to launch at full boost.....

Engine bolt-ons: Red's 93 chip, 160 degree 'stat, colder plugs, KN filter, 3" intake, LT1 MAF, Translator Plus, stock intercooler w/Kenny Duttweiler neck, TA-49 turbo, adjustable wastegate rod, adjustable f/p regulator, Walbro 340, 3" dp, gutted 3" cat, dual 2 1/2", oversized, stock-appearing crossflow muffler.

Trans mods: Full Art Carr TH200-4R rebuild, 12", 3000 RPM stall conv.

Rear: Eaton posi w/redline clutch pack, 3.42 gears, Moser 30-spline forged axles.

The trick to running meth and getting good gains from it is having the balls to throw the timing at it and pulling the fuel. I went from 406 to 462 rwhp with the meth, but I did it like the GN guys in that I upped the boost along with throwing the meth to it to make the extra power. The first pull with the meth was 399rwhp, so I was actually DOWN 7 hp, after throwing 2,4, then 6 degrees at it it was up to 462, I would imagine it could have taken another 4-6 degrees, but that's all I wanted to push a stock 4.6 shortblock.

Great info guys, anyone else?

meth is great. intercooler too small? meth will help you. not running enough injector? meth will help you. dont feel like buying 5 gals of C16 every weekend? again, it will help you!
