Faster on alky than race gas?

[Not Avg 6]

I'm trying to understand how some people are going faster on alky than on racing gas. Lookiing for examples and some explanation.

Thanks

I would think the biggest difference would be people using it with smaller I/C's as the alky would cool the air better. Not sure you would see much of a difference when using 116 with a quality F/M!

So do you think with a quality FM, you could put close to a 116 tune on a car with today's alky kits runniing meth?

i ran my fastes pass so far running 93 and alky vs a race mix alone
the biggest differenc i feel is in my wallet , no more $10 gallon fuel

WOW :redface: Great thread.
I'm on the fence and leaning over on the alky side. Doing my research trying to gather enough info to push me over.

That's incredible!!! Almost too hard to believe, but great answer.
Finically, that's where I''m at. Looking at the price of race gas, I don't know if i want to go thur another season spending that kind of money on gas.

I agree 100% about the $$ issue but also you wont get caught with your pants down on the street with alky(unless you forget to fill your resovoir)
I used to mix 93 & 110 octane for my combo and it was a pain to go get pump gas then drive to where my drum was stored and pump out the fuel, etc...you get the picture. On more than one occasion I had to back down from a vette or mustang because I was just on 93, with race chip and boost set to 20 psi

Now my car is locked & loaded @24 psi with ALKYCONTROL at all times.

I just installed my meth kit on the srt-4 and can now run 22.5 psi with no knock on 93 octane with alky spraying and only 17.5 psi with the 93 octane alone. no more leaded fuel for me. For the street cars the alky kit is the way to go. Definitly getting one for the t-type soon. Well worth the money.

Here's a nice simple writeup on why methanol makes more power than gasoline

Good info guys, I teaning some more.

Good info guys, I teaning some more.

Now Mike, what more evidence do you need more the trying to keep up with me :biggrin: LOLO. I think thats what sparked your interest the most.
You saw it with your own eyes and seeing is believing.
Just do it! You'll never look back.

Well the great thing is that you can turn it on and if you dont want to use it just turn it off. I have run my best times using alky. I only run methanol and nothing else. I am not trying to break records and be the fastest with using the least. I just want to keep my stuff together and have a good time doing it safely. Its good insurance, however once you start using it you will not want to turn it off. It is progressive and very managable.

Ha.ha.ha. LOL Friendly competition is cool.. Trying to keep up with guys like you and Dr. Boost isn't easy. Thanks

P.S. Be careful you might be putting that big one on sooner than you think?

I wasn't saying don't use the Alky. The question as I took it was simply race gas v/s alky as far as power. I don't see how a car with 93 & alky is going to make more power than straight 116!

If you are talking cost on the two that is a no brainer. I have a Alky control kit on one street car in progress and plan on putting one on my main street car, I think it is a great product.

alky only sprays under boost so you get to drive around on 93 and never fear stomping down (except for the limited traction the street offers) , you could even run 87octane as long as you tune for it when under boost , 87 will tolerate slightly less timing and boost but you could add in more alky and possibly get nearly the same power as with the 93, ive just never seen the 20-30cents a gallon difference as sufficient reason to try 87 , but even with 87 and lower boost you will still have a powerful ride on the street thats ready for all foolish enough to mess with granpa's car.

no real need to turn it off unless you want run race gas only , then just turn off the alky, drain the 93 as you would have been doing before alky add race gas and adjust the tuning according for the fuel
you could always leave it on and run both alky and race fuel but unless you tune for it you're just wasting your money on the race fuel and will most likely be slower and you will then have to readjust your tune when you go back to 93

at the track i am usually looking for the next hidden 10th out of the combo so i run the car closer to the edge , but when i leave i dial back boost and timing and dial alky just a tad richer for the street , still plenty of performance even dialed back and will usually make my first pass in this safer mode then work my way back to where i was the previous session and then tune ( timing ,adjust fuel+alky -boost) and to tune to the edge a little further

So do you think with a quality FM, you could put close to a 116 tune on a car with today's alky kits runniing meth?

Yes, conservatively close. With a mixture of race fuel and pump gas + alky sure!!

P.S. Be careful you might be putting that big one on sooner than you think?

Its already on!

116 is not the easiest to ignite and needs lots of timing to burn

alky is a variable octane since its a mix , and allows for dialing the octane to the need , better burn more power , also add in the cooling effect to the incoming air , more fuel in the cylinder becomes possible along with the cooling effect on the combustion chamber so tune can be pushed even further before preignition or detonation

i was running better on a blend of 93 and 112 (3:1) than i was on straight 16, but that method of mixing is a gamble as to whats in the tank
alky i know i have 93 and i know what the alky is spraying , to me its much less of a gamble and snce i have control of the alky if i find the mix is a little light (signs of KR) i can increase the alky with just the turn of the dial.

No, I did'nt think you meant don't use alky. I was just asking questions and appreciate your advise. You guys make the decision alot easier. Thanks

Rick87GN,
What!! Your nuts.
