my friends IAT's go from 200 deg to 50 deg instantly as it is used.....so I would consider it a power adder, just like some race classes limit turbo sameor even the use of an intercooler, meth is also a power building factor.

It's not a power adder, it simply supports a power adder in the same sence that an intercooler or higher octane do. Any further discussion than that is simply assinine. It's a SUPPORTING MOD, nothing more. You can argue that until you're blue in the face, but it could only be because you don't comprehend the function of methanol and/or supporting mods.

If you spray a 50hp shot of nitrous to cool the charge from your blower or turbo enough for it to pick up 50hp itself then you pick up 100hp, = two power adders.

If you spray enough methanol for your turbo or blower to pick up 50hp, you pick up 50 HP from your blower or turbo.

Thanks. I don't have a lift......my best friend and mechanic does. I don't know how to weld......he does. Almost every mod on my car has some sort of custom fabrication, that is over my head. Not all, but most.

I know methanol isn't a "common sense" part. But the fact that it is in no way a literal "power adder" seems to be common sense.

turbo: 100hp to infinite power increase
supercharger: 100hp to infinite
nitrous: 50 to infinite hp

meth: maybe 50hp MAX with a good tune

LOL at you opinion of a PA

Now go sell some real power adders.....called Prochargers

Given that line of reasoning, then ice on the intake is a power adder too, because of the same cooling effect.

Don't misunderstand, that is NOT a flame on you andereck, I'm just driving a semi-truck thru the hole in that particular line of reasoning.

I'm leaning towards onfire on this one, as it does not add O2.

Oh and I use Meth (blended 50/50 with water) on my normally aspirated LT4 (I still have not got that STS kit installed!); does it "add power" YES!

Should it be classified / regulated as a true Power Adder like turbos, nitrous, and superchargers? I don't know...

But I do know this, if it is considered a stand-alone Power Adder, then Intercoolers should be too, as they perform the same function.

Great point that I don't think has been mentioned yet.

Should an N/A car with meth run in the single power adder classes? That would be an embarrassing day of racing for the poor N/A guy with his big bad meth set-up getting waxed all day by blower/turbo cars.

andereck

Methanol is rules controversial some places. Take the NMCA for example. I would love for my friend to be able to run ProStreet in the NMCA but they specifically won't allow centrifugal blowers or turbochargers on methanol. They will however allow roots blowers to run methanol, and they do. Those cars are more like stickered up ProModifieds than ProStreet cars in my opinion. Why? A centrifugally blown or turbocharged car at the same weight on methanol would embarrass the roots blown cars that dominate the class today. Keep in mind that roots cars run over 60 psi.

here is the solution if they ban methanol... use ethanol and mix some meth in to cheat. If you aren't cheating you aren't winning

I think for the same class they should ban Air/Water intercoolers if they ban methanol since they are power adders lol.

This really is a ridiculous discussion.

Methanol is a fuel that does not add oxygen to the combustion process.

If you want to really bake your noodle, discuss whether or not Nitromethane is a "power adder." Unlike Methanol, Nitro does add oxygen to the combustion process and can double your power without the use of forced induction.

I can't see why - it hasn't made my car any faster. I ran a few weeks back at Norwalk with the meth and without the meth on back to back runs. The car ran *exactly* the same. Same sixty foot, same 1/4 ET and MPH.

The only thing I find the meth useful for is keeping the power firm when really romping on it in the summer heat.

Mike, its been proven? Really that must be why all of us suz busa riders run best on low octane fuel. There is even a race 92....but most seem to do just as well on 87. If you run 116 you ll kill the power. Ofcourse this is more apparent in small engines that will be able to take advantage of the energy. I think its also pretty proven that there is more energy in lower octane fuels.

Mike, please dont make a blanket statement with out something? Can you quote the energy differences? Hel if Im wrong Im wrong, but other then your opinion you gave no relavent information?

Doesnt matter anyways, this is about meth.......By itself it doesnt ad power. Power adders do by themselves ad power.

Soo......... how do you guys define a street car? LOL

[hijack]1320, I work downstairs from a bunch of fuels blending chemists. Talk about get more info than you ever wanted. . . Anyway, I didn't write down energy contents during this conversation, which was over a year ago, but I do remember concluding that summer vs. winter fuels had a larger energy difference than 87 vs. 93 octane.

All theory aside, I kept 2 magazine articles proving this to be true.

Hot Rod, December 2001, "Octane Shootout"
Engine: 360 Chrysler, 10.4/1 compression
87 octane: 396 hp
91 octane: 402 hp
114 octane: 408 hp
Timing was adjusted for max power on each fuel. The 87 and 91 both made best power at 36 deg timing, while the 114 did best at 31 deg. This is not a typo. From the article, "we discovered that our presumption that higher-octane fuels burn slower than lower-octane fuels is largely incorrect. There are too many other fuel-fomulation issues at work to assign a general rule about octane."

Hot Rod, January 2004, "The Full Scream"
Engine: 408 Chevy, 9.9/1 compression
91 octane: 637 hp
114 octane: 651 hp
From the article, "It was evident from plug inspections that the engine was not experiencing detonation on the pump gas. . . our increase on power was more likely due to the fact that the structure of street gas includes hydrocarbons that may not vaporize until 400 deg, whereas the race gas vaporizes at perhaps 275 degrees."

The crack head up the street thinks Meth is a power adder!

ss53mech

I don't think it should be considered a power adder, but for racing intent I think it should be class controlled. There can be some pretty nasty differences with and without it. I like the idea of cars running a roots setup being allowed to run it and cars on centrifugal/turbo setups should not. I have always loved roots setups, but they are just not as efficient as the others.

As for octane stuff, I have seen it go both ways. Some cars make more power on higher some on lower. I believe it is relative to the particular cylinder head/ compression ratio for octane efficiency.
