Huffers??

Post  jason on January 1st 2013, 12:52 am

I don't know a lot about them, but I was wondering if I have to run alcohol only when it's injected? Does anyone run race gas and use injectors on the blower manifold? I was looking at a littlefield 12/71 or 14/71. I don't want carbs. That's my thoughts for the week . Sorry for the stupid question.

You can have the system calibrated for gas.

Would it be easier to run alky? I see that a lot of guys aren't running cooling systems for one. Who's system do most guys use for both gas and alky?

what are you using it for?

Have you talked with Enderly, Hilborn or Rons?

I don't care for Alky, its to much maintence and a PITA as far as I'm concerned, but it does have its place in certian applications.

Are you looking to run race gas in a blown application?

I would prefer to run race gas. It would be mostly a track car since I'm building a street car/drag car now. It already has an a460 block Bryant crank and Oliver rods. It might see a little street time.

Blown applications are made for methanol. It can be done with gas with a good tune, but you really need to talk to people who do this every day. Methanol is used because as it is mixed and compressed it helps to cool the intake charge and keep the engine running cooler. Lots of guys running gas in blown centrifugal setups and also roots style setups. If you are looking to make 4 digit+ power, alky is probably going to be the better way to go.

So I should just rule out gas then? Who has run gas successfully? And how much power they making?

I wouldn't rule out gas, infact I'd use gas with carbs if its going to see any street time.

If I read the info correctly, this is going to be a track deal.

Here is a realistic expectation for what can be done with gas and a smaller blower. With a larger displacement blower and more cubes, 4 digit power is achievable. This was just recently done and an honest dyno number. The dyno sheet is on page 5 I believe, and made like 950hp on 110 race gas.

Yeah mostly track time. My set up is a 572 with a 250 shot, it made 815 hp N/A and on a weak tune up went 8.80's . So I'd like to go faster, maybe it would be better to put twins on it. I'm the only guy in town running a big ford, but there's about a dozen guys running turbos. That's why I'm thinking injected super charger. Something different around here.

There are a lot of good ways to get more hp reliably without doing the blower route. C heads and a single 1450QFX did 1200 on gas with a 640" deal. There have been some A head combo's that were over 1100, add a little giggle to that and you would be flying. I would love to do a blower engine some day, just for the cool factor, but it would be on methanol if I did it. I can't remember who I was talking to about the forced induction stuff, Dave McClane I believe, but they told me that with gas you can only go so far because of the heat produced. Dave builds some monster truck engines down in MO. On the other hand the methanol acts as a coolant and going into the 1500hp area is very doable without getting really exotic. Cool

The cool factor is in the equation, but I have stupid big tires so Hooking it shouldn't be to bad. Ok maybe turbos is the only way. If I wanted to make about 2000 hp/+ is an A head good? I've got a set of edelbrocks on it now that are hogged out.

With the power adders you are talking about pretty much any head will work. Your horsepower limit will be set with the blower rather than head.

I would run methanol and either twins 88-91 range or a blower and leave your compression where it is unless it is 13:1 or 14:1.

2000+ hp Shocked You are definately going to need those big ole tires, and one heck of a chassis to put it down the track. Laughing There is no way to do that kind of a goal on gas, you are definately going to have to do methanol if you are doing forced induction. Frank Kramer is a mod tractor puller from the Netherlands, you can search his stuff on here, and he is running blown A head engines. Not sure what he is making power wise with them, but I'd guess it's close to that level at least. Another option that may or may not be the way you want to go is talk to Jon Kasse about his big inch moutain motors. They aren't cheap, but that kind of power level isn't going to be cheap or low maintenance. I think the last I heard that they were above 1700hp with these engines and probably closer to 1800hp. Cool

Make sure the balance of the car can handle it....... Making the numbers is the easy part !! king

I'm not that familiar with blowers but 2000plus would be easy with twin turbos on a bbf. We've routinely made that with a single on small blocks.

I back halved my car with a 4 link, wishbone, and A/R bar. The engine is 12-1 comp. and it weighs 3500 I run a coan glide and had Lenny at ultimate redo the converter . First hit off the trailer with a 250 shot went 1.25 in the 60. I figured if I step things up with the engine I'm gonna cut the cage out and do a funny car cage in C/M and have to change the trans to.i have to find out what fuel injection to use that's easiest to tune with.

GMC style Blower's are cool, but if you want to hang with the turbo's you will nead to run methanol, and maybe a little nitro. Sounds kind of like a ProMod then. In the Houston area, Connely at CCP did alot of turbo work, and Frankie Taylor had a blown Pro Mod Corvette. The CCP car held the track record at HMP at 4.41 for a while, until Taylor knocked it down to the 3.80's or so. I am no expert by any means on these engines, I am just going by the times I see at the track, with some of the fastest one's we had around here. Good luck with your build, and I hope you do choose the methanol injected blower, turbo's just don't have the wow factor for me.

I'm building a 71 challenger tube chassis car for a guy right now that has a 14/71 littlefield and injector set up. He's not sure if he's gonna use it now, so I might grab it .

Give me a call and I'll tell you what I know. I'm running a 6-71 on alcohol with a stroker Cleveland. Planning to switch to E-85 for ease of maintenance. Enderle injection is simple and works great. Easy to learn and tune.
