I changed over to a carb also.

I would think just bigger injectors ,fuel pump, and some one that could tune it.

Me and my dad both run ours on Methanol in the 9's but we're not LS1s.

I love it, don't see going back to racing fuel. Sure is some stinky **** though, I'd imagine they think I'm crying at the ticket booth every time I roll up rubbing my eyes.

Joe Overton ran his LT1 on meth. He was using an Accel gen 7 and big injectors. He could get you set up.

please excuse my ignorance on the subject. but why does methanol require a bigger injector than the same setup would with conventional gas?

because Methanol doesn't have the same BTU content of gasoline so you have to use more of it to get the same energy. The plus is that it has a high high octane kinda like that of Diesel. The advantage is that you can run high boost with it and it will still burn very "cool" in comparision to gasoline. I am surprised more people don't use it as it is cheaper than race gas from the last time I had to buy some for my grandpa.

Actually with Meth you burn 2.5 times more fuel to make the same power. Now meth is cheaper, its only $4.oo a gallon.

It's cheaper but because you have to burn more of it it almost becomes a wash. Plus it is somewhat of a pain having to go get a drum every few weeks and taking 25 gallons for just 3 days of racing but the added ET/60 ft. is well worth it.

In the summer during even the hottest days I never use my fan. I use around 2 gallons a run depending on how much warmup I do.

I get a 50 gallon drum for $108 then $10 for the additive lube.

Plus you can run higher boost with the methanol before detonation. I am just curious as to why more LSx folks don't run it.

Thanks everyone for your replies. I figure it just isn't the most popular thing to run in the LS series cars.

What if we didn't use the additive lube?

Thanks.

As far as I know the lube is used to prevent the alcohol from gumming up/corroding the lines, carb etc. If you didn't use it and the car sat a while without lube in the fuel then it is to my understanding that things would start to get clogged/ate up.

Plus it helps lessen the burn on your eyes.

EDIT: Here's a good read...

Good answers, I agree with most.
A bunch of my buddies use alcohol, they all use lube and they all drain the cell before loading up to leave. The lube does help keep the pumps running better, and it does help with the burning fumes. The bracket guys like it because the ET stays the same for a much bigger weather window, easy to dial in from morning to night. It does take ~1.8-2 times more fuel, so you need to make sure the cell & pump is big enough. Cooling is much easier also, I know a bunch of injected guys that don't even run water.
People don't run it, become it's different, and guys don't like to risk it I guess.

For me I have a belt driven pump and vacuum pump so that helps a lot but it's pricey, the only necessities are a pump to put out a decent amount and

Pre-race I have to run the car more than others (you can install a lean out which helps), that's the only difference there. Round by round I empty the water pulled by the vacuum pump (not a must, I just do it). Post race I turn off the water pump to get it up around 200 and shut the car off, when I get home I stick a shop vac into the left valve cover to suck out all of the moisture so that the oil doesn't milk bad. I don't run the lines out of fuel after the race.

Mine actually wasn't that consistant but that was in part to being fat. I love it, my car was just an experiment and the added ET was well worth it.

One of our buddies was scared to death of his car doing a massive wheelie and it wasn't anything spectacular but all he did was put it on alcohol and the very first pass with little burnout he put it immediately on the bumper and destroyed the front end

EDIT: It will also junk cheapy oil filters. I went about 2 months on cheap filters and the inside kept collapsing which killed my oil pressure. Swapped to a Wix racing filter and it has been perfect.
