Would like to run alcohol carb instead of Injection

[rundeep66]

I was thinking about running an alcohol carb this year. I was wondering will I still gain the power from a carb instead of running the ron or a hilborn style. I know injection is always better. I always thought you could drop about .2 to .25 from your et. by running alcohol injection. I'm just starting out with this. I figure I would start with a carb it may be a little cheaper.

Injection is usually close to a tenth faster, I've did the swap both ways a few times. www.apdracing.com Give these guys a call for great alky carb.

I rather doubt that. Alky carbs aren't exactly cheap these days, for a good one.

If you have a single carb manifold, get a Ron's unit.

If you have a tunnel ram, go with an Enderle.

If you don't have a manifold and like the Nostalgia look, get the stacks.

Motor in the car it's a 1998 camaro, it's not the easiest to do a intake swap. I have a 1150 worked I was just going to have it switched over. It should be about 500 or so. I've been keeping up with you guys post about alky I'm going to try it out this season. I figured I would loose about a .10.

At least a .10, if not more. Mech Inj will decrease it another .2 to .3 over a carb, and make the car deadly consistent.

I dont see over a tenth from a rons toilet to a carb, atleast both properly setup. Get someone good to do the change over on the carb if not you'll fight it ! Seem it way to many times.

I got a Rupert Gas carb and love it. If I was going to alcohol, which I have thought about it would not be Rupert....it would be APD. What would one expect to see in e.t gain going to alky on a 496 BBC in a dragster? Car runs around 5.10 (5.06 best with me)with a best e.t. of 4.96 with a smaller driver. What do you think?

I thought Rupert stirctly did Alky Carbs??? I have owned nothing but Rupert carbs and after watching others struggle with their APD, I would hesitate to own it unless it came directly off of Randy's car.

As for injection to a carb, when we took the hat injection off our dragster it went from 7.80's to 7.90's. It was .15-.20 difference. The response and torque off injection is far greater than a single carb.

Yeah my gas carb is from Rupert, my dads is Rupert and my brothers is by Rupert. I had my car on alcohol at the beginning of the 07 season, but never run it at the track. It was during the winter and I decided to go to gas since this is what our other 2 cars were on. When I was at Beech Bend last March I sold my Rupert Alky carb back to him and bought a gas carb that he went through. Just wondering what gain I could expect if I did switch.

When i switched to rupert alky stuff it was worth .10 in the 1/4.. apd was worth .18

Thanks David.

Thanks David.

Not a problem, IMO alky has to many upsides not to run it.

Dave's numbers are on the money. The only thing to remember with alky is to get that oil temp up. Even though your water temp is up, let the oil soak up some heat. Try to be 165 or better and you will have no issues with milky oil.
