I see how it is Rich, just ignore me when I suggest it.



Not saying it would necessarily be the best, but it would definitely be different, and you would have plenty of cubes to make power so you could keep RPM down where it's cheap(ish).

 

you know you'd rather see a big polished 88mm turbo sitting out in front of an LSx than a procharger.

there are guys on TheTurboForums that have made 1000rwhp on stock 6.0 block, crank and ported stock heads

Here is a thread discussing the 6.0.

 

Tube car, Altered style

or Top Dragster type

or maybe a long wheel base roadster.

I have a short roadster now.

Jake: one of the neat things about alcohol is that you do not need intercooling. Pleanty of alcohol cars with Roots style blowers running 25-30psi with no problems. And those blowers make a ton more heat than a centrifugal or a turbo.

Go with the long WB roadster.....34 chevy S&W will make you one cheap.

I don't like the altered cars.







P.S. paint naked ladies on the side!

 

Rich not Rich,

The 9000 RPM LSX idea was fun, too much maintenance.
A pay and play BBC would fit the bill, thats no fun.

Might as well put the exhaust to work, lets talk twin turbos!

You're right, how silly of me. TWO 88's would look much better up front.

 

Fine, you don't need it... but doesn't it still help? When working with gas engines (as I'm sure you know), an intercooler is a (relatively) cheap way to add a bunch of horsepower to an FI car. Is that not the case with alcohol?

Seems silly to skip such a thing just because you're not getting any knock.

 

I can't say for sure. But did you ever see/feel how cold the manfold on an injected alcohol car is? I have actually seen frost form on the hat. Alcohol has a high heat of vaoprization and alcohol drag motors run quite rich. I think there is much less to gain than on a gas motor.

methanol = 37.4kJ/mol*2.3 (to compensate for AF ratio) = ~86
gasoline ~20kJ/mol
86/20 = ~4 times as much exaporative cooling with methanol as with gas

With a much cooler mixture to start with, there is much less to gain from intercooling. That's why water/methanol injection works so well and to a point obviates the need for an IC.

Cool, thanks!

 

If your going with a blower.....Def go for the alky.

I have been readin up on it...seems it uses more fuel and the unburned fuel is used as a coolant for the cylinder. Without the extra fuel it would melt the pistons




If you build a LSx motor or a LTx motor, your just going to spend a bunch of money and never win anything.

 

HP is HP. There should be little difference between a 468 LSX and a 468 BBC, and you may even be able to get better heads for the LSX (I don't really know though). Of course if you are talking about forced induction head flow is not that big of a concern.

 

Not really..... a big cube LS vs. a big cube BBC...I go with the BBC jst because its cheaper and easier to keep up.

 

That I will agree with. But if you are talking about winning races then HP is HP. Of course I guess for the same price you can build a bigger BBC than you could a big cube LSX, and consequently make more power.

Heck I don't know I'm just a rookie.

 

Rich,
Running out of ideas quickly, one of these would make big power bolted
on the front of a 6.0L truck block! Go with a long wheel base altered,
that way you can see and hear the excitement up front and still have
enough wheelbase to keep it moving in a straight line.

Want a challenge? Mount two smaller units turned with the same belt.
