I am seriously considering switching to Alky sometime here in the not so distant future, and I am looking for input from those who race with a carbureted Alky Setup. Do you like it? What all is involved in the swap? As far as I know, all I will need to do is buy an Alky carb, new bigger fuel line for the feed line, larger capacity fuel pump and regulator, and as far as I know that should be about it, is there anything that I am missing? Also, I have read differing opinions on the amount of maintenance required, and I was wondering how much is truly involved? Will I have to run a special oil, or will I be able to run the same oil (shell Rotella, changed every 30 runs)? I'm just getting tired of buying $100.00 worth of race gas for a two day race, only to have a problem getting the car cool for the late rounds of a bracket race, when they have us practically hot lapping. Sorry for the book, I'm just trying to see what I'm getting into.

Figure two gallons a pass roughly, which also includes fuel used for warm ups. I use Klotz fuel lube, don't have any issues with my injection setup. I never drain the system, or do anything special other than keep it sealed off from outside air when possible. The most important thing is to fully warm the motor. I warm mine to 210 or so, which heat soaks everything including the tranny. I launch at 185 to 190. A lean out of some sort is mandatory for decent warm up, and saves a lot of fuel. The heat also clears the oil if you get some milking. If you get some milking, you have a very rich idle, or are running it too cool at some point. To help with fumes, do what you can to direct exhaust out from under the car. The consistency and ease of going later rounds is a big advantage of alky. You often will be working to get heat into the motor to leave the line warm enough. Run plug gaps a bit tighter, and two less degrees timing than gas. I run my plug gaps at .032 to .027, and haven't seen any difference between the two.

I thought about e-85, but my fuel system was not put together by me, I've only got a old holley blue pump and regulator, and only -8 line from front to back, and I figure if I'm going to have to upgrade all of that, I might as well go all the way to methanol. I like the idea of nothing but a carb change, but it doesn't look like it will be that simple.

Greg covered it pretty well. My 2-cents: - keep it sealed off from outside air when possible
- cap the vents between race days
- Use a lube in the alky
- Get the engine HOT (200) at the end of the race day, shut down and pull the breathers for a little while
- The carb idle calibration is very important, some are too rich; check it
You will need a fuel filter compatible with alky, typically a stainless steel mesh screen type.
I love it (Ron's Flying Toilet injection). I have run both E85 and methanol (alky). Right now alky can be really cheap, I pay $150/barrel = $2.73/gallon. You will use close to double the fuel per day compared to gasoline.

Everywhere I ask, everyone says get a Rons toilet setup, I have never heard one negative about them. I don't know much about injection, so that's why I hadn't really considered it, how easy is it to tune and get running right for a rookie like me?? Quote:

Order and work with the guys at www.killerrons.com. They are factory backed, and are the best customer service rather than calling/ordering from www.ronsfuel.com
Check out the web site, they have lots of good FAQ. And when you are ready to order, they will get the tune close when you order from them.

You originally asked about an alky carb setup, so I wasn't trying to convince you to go injection. But I honestly think it is the right way to go. But there is nothing wrong with a good complete alky carb fuel system.
Check the total cost and the "kit" cost of a Ron's injection system isn't as high as it might initially look. Their kits include the fuel pump ($350-450), fuel filter($100), pump drive/installation brackets ($225), extra tuning pills (jets), etc. etc. So when you add it all up, it isn't much more than a good, complete alky carb fuel system setup.
If you want simple, go with a carb. If you want the best, go with injection.
I ran my injection without a primer system for a couple years. But after spending a little more for the Ron's "Primer Plus" I highly recommend spending the money. It makes cold weather starting easier, warms up better (running on gasoline), and just starts better even between round (IMO).
