(Another) Another octane question

Jmadd...didn't you just have to rebuild one after it locked up (forgot if it was you or not...)

 

With that timing and compression...and the cost of gernading a motor to save a few bucks...I'd say stay with 108.

I'm sure you'd be ok with a 50/50 or 25/75 mix. But....is it worth saving a few bucks?

 

Just my opinion.

 

Why don't you go to alky? More power, same price. (Yeah, I know alky is cheaper, but...you burn twice as much and use more premix too....)

Yeah, I locked one up.....ran the right carb out of gas. I'm not a cheapskate, so I'll probably stay with 108. BTW Klotz gas is about 10 bucks a gallon.I've thought about alky; but purging seems like such a hassle. If I get beat on my 421 by a DS650 on nitrous (local rival of sorts), I'll go straight to alcohol.

They don't have any gas stations around you that sell race fuel?

I only pay 5 bucks a gallon for race fuel around here, 110 octane.

Sheesh...in that case, alky would be cheaper...

It'll take one healthy DS on spray to beat a good tuned 421 cub....

I'm not saying it can't be done...but, they'll have 3 to 4 times the money into that DS get r done!!

I would stick with the race fuel and not run the chance of tearing up the motor again............

 

I pay around $5 a gallon here too. If gas prices keep going up the way they are I'm probably going to be paying less for race fuel than I am for cheap ass unleaded.................. :shoothead:

As much racing that happens in Memphis TN there has to be some body in that town that sells race fuel. Heck you could probably just go to a race, get in to the pits, and find some body selling fuel. It is only a 100 mile drive from where you are. Go watch a night of racing, get some race fuel way cheaper than 10 bucks a gallon. That is a win win situation. Klotz makes some great products, but there is no way I would pay 10 bucks a gallon. How much is shipping on a 5 gallon can? I bet it is killer since it is hazmat.

I've only bought 1 drum of Klotz so far. I buy from a Klotz dealer that I know, and he swears that HE pays around $500 or so for 55 gallons (from what I remember), and I think I bought it for about $515 if I remember correctly. It's SUPPOSED to be better gas b/c each drum is analyzed for octane rating and some other bs. I can get turbo blue at a decent price close to here, but I haven't researched its quality.

 

Didn't mean to turn this into fuel comparison thread, but I welcome all opinions.

 

Thanks.
