Considering Switching To Alky... #1372903 01/20/13 08:48 PM 01/20/13 08:48 PM

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. 1970 Dart Drag Car

I used a magnafuel fuel pump, #10 an to the front and 8an return. I ran VR1 50 wt oil. I set my pump at 9psi with a fuel log and bypass valve. It idled at 3psi, then went to 9 at wot. I have a ross built 9375 dominator for a carb. The combo worked very good and the engine never ran hot even with a 1 inch 1 row radiator 19x22. I filtered my fuel while filling the cell. 3.5 gallons. I never really had an issue, except, you have to get the engine warmed up or you may milk your fuel. A vacuum system will help.

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 think that may be a very good option instead of straight Methanol E85- needs 1.4 times as much fuel as gas. Methanol- needs 2.2 times a much fuel as gas. If you built a good fuel system with plenty of capacity, then a change to E85 is dirt simple. You still get some cooling benefits, plus the fuel is fairly cheap. Buy it by the barrel after testing for percent ethanol. Best time is in the summer. Some Co Ops sell E98 in barrels as well. Some people report that the ethanol content can very, so testing is important. Last edited by gregsdart; 01/21/13 11:25 AM.

I do run the carb bowls dry as I run an electric pump and let the carb run out of fuel at the end of every raceday. That is about it for maintenance for me. I did remove the foam from my plastic cell. At less than $3 a gallon and a wide tuning window, I wish I would have switched earlier. I run a mallory 250 pump, -10 line to pump, -8 to carb and -6 return. engine is a 572 in a dragster. bob spelic

I like the idea of nothing but a carb change, but it doesn't look like it will be that simple. 1970 Dart Drag Car

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.

I use a Pro Systems SV-1 and thier special regulator. I really like it.I also use a lean out valve to help build heat. Methanol and E-95 can be hard to start if the temp is below about 40*.I've sprayed carb cleaner through the lean out to help cold weather starting.I also like to spray fogging oil in the lean out valve after a race to keep corrison down on the cyl walls.Vacuum pump and warm engine temps also help.I like to use a gapless top ring to help keep the oil a bit cleaner. You might also search alky,alcohol or methanol here,dragraceresults.com and yellowbullet.com. There is lots of helpful info around.Good Luck! 7556257-bracketnationals.jpg (57 downloads)

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. 1993 Daytona, 5.50 at 130mph (1/8) 1.19 sixty ft (PG). Link to 572 B1 - Part 1

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). 7557773-Toilet_intake1001.jpg (129 downloads)

I run a star vacuum pump and the oil stays crystal clear. I also run rons toilets. Only my pump and injectors are from them and everything else is enderle. If you do decide to run injection instead of a carb I agree with the others, have it setup by someone in the know.
