found gold, second question

Thinking about going to gas!
How much hp does alc. make over gas?
I know the sound will not be the same or the smell anything else you can think of?
Thanks for all the input

 

Blown gas is a very narrow tuning window. Not a lot of room for error. Where an alcohol engine will run nice and powerful a little fat, and lots of room before stuff melts on the lean side, not so for gas. A little fat and the thing will try and blubber and lose big power. Gas is also notorious for hurting parts. Then you have the heat issue that alcohol does not have. Alcohol is cool and basically is its own intercooler. On gas, heat is your enemy. You will find that the deal may want an intercooler, etc. Then we deal with price of fuel . . . And then there is the choice of fuel, because as you up boost, you want a higher octane rating. And if you drop, you will make more power with less octane. As close to detonation as you can get without detonating is your largest power made. Then the next, where lots of guys out there know how to tune a general blown alcohol application and very few that can properly tune blown gas.
But having so said, these are the benefits to alcohol. Both tuned perfectly in a less that top alcohol engine, the power differences are not as big as you would think.

 

with gas it will be harder on parts......run slower....and hotter.....gas is more $$. stick with what you have Steve....don't let frustration win. stop by the shop this week.....should be there working on the old heap.

 

Dont forget about having to change the clearances in the blower for gas...

The blower will expand a lot more because it's not being cooled...

 

A long time ago when I built my first 392 hemi. It was injected on gas. I didn't know anything about anything- (still don't) It was really hard to get the car to run right on gas. The tuning window is very narrow and it seemed as though the motor ran hot. When I changed it over to alcohol it settled down a ton. It wasn't hot anymore. I could miss the tune-up and it would still start and run. And when it was all done and said it seemed easier on parts with alcohol than it was with gas. The only negative to alcohol is draining the tank at the end of the weekend. Otherwise it is easier to tune, easier on parts and cheaper by the gallon. Dave Germain

 

Pretty much what Mr. Germain said. Been down the same road.
Besides, changing fuel isn't going to fix the problems you had in the other thread.

 

I run blown gas, and I can tell you I have a pile of burnt pistons over in the corner of the shop to get to 35 psi of boost on gas and the motors living.
There's not much your doing inside your current blown alcohol motor that the blown gas deal would like. Unless you just want the challenge, I'd work out your tune up on your alcohol deal, much more forgiving.
But the waters fine if you want to jump in.

BT,DT with blown gas,(old "Top Gas" racer). I used to have a couple of bushel baskets full of "singed" and "hammered" 392 (464) Chrysler pistons. Years ago some guys from Texas bought'em all from me. They said that they welded'em up, regroved'em and ran them. Don't know if it was true...but that's what they said.

 

thanks to all, long winter,
Darren, will stop by this week sometime.
again thanks to all
