I have a 12 to 1 454 and would like to know if I can put a gas blower on it , using racing gas?

There was a guy.....who bought all the parts for a machine shop to put his deal together and bought 11.5 to 1 pistons for it. The machine shop knew it was a blown deal and yet they put the motor together anyway. The blower was a "good" 8/71. They put the blower at 1 to 1. The thing lived in a Sanger hydro at 8500 rpm and never hurt a thing. 5 years.
Racing gas. And we are at 4500 ft static elevation.
468 BBC. Now on alcohol.
I don't recommend but there ya go.

It was still in one piece at the end of the weekend. :)hand The compression ratio is only have of the equation here. Of course alky and 12 to 1 are happy. Even at 30lbs of boost. The question here is, why would anyone build a 12 to 1 blown gas if they didn't have to? Its stupid. And of course I choose to race in a class with stupid ass, costly rules.:D

Ah come on guys. Nobody asked about boost here. It's do able,..... stupid, moronic, and insane. But do able. 12to1 and 14 pounds of boost is only 24 to 1. 8to1 and 30lbs of boost is 24 to 1. Not exactly the same, but close enough to realize it can be done for the right amount of $$$$ And nobody even asked about gas. Aaah the gas. I have seen it as high as 12.00 a gallon

Not going here but 12 to 1 with a blower and gas is do-able depending on the heads, block, and as stated already the drive ratio intended. But again as already stated it could be a perfect alcohol deal, depending on the rest of the combo. Saying no to an open question like that is not a good idea without more detail. IMLAO.

Realistically I think for the way we run the boats out there, 20 gallons will take you pretty far. It would be at least equivalent to the 8 gallon T-tank range on race fuel, probably a little more based upon your tuneup. I just worry about the oil issue with methanol, having to change the oil so much. There is always a tow rope if you want to find out how far it will go for sure.
