430+hp 340 possibilities

Well a fine tuned motor can work on pump gas (I'd still use racing gas) On a 11 - 11.5 use can mix it to keep costs down but what a difference in performance. I used to motors and convinced all my customers to mix their fuel and today with levels of alcohol in the fuel unknown I would highly recommend it. Just how many miles a year do the average people drive these cars. Not much. When you add 2 gal. race gas to a 15 gal tank you put in 13 gal of pump gas plus 2 gal race gas add total $$ divide by 15 and that's your cost. Here Premium pump gas is 4.00 x 13 = 52.00 race fuel is 12.00 in the can x 2 = 24.00 total $76.00 / 15 = $5.07 a buck more. If you use reg. at 3.39 the price is only $4.60 and 2 gals. of leaded 110 makes a big difference in unleaded fuel.
I agree. But…. It honestly doesn’t really seem to fit the thread in the way of the OP’s builds and what he has.
Also, IMO, the adding of race fuel to a driver for regular driving purposes is a bit much on the extra chore level for a regular car that’s driven & to be enjoyed.

If one was willing to add some race fuel to there car, that’s fine, just not a solution for most I think. You brake it down easy enough to justify the cost. It works out. However, to keep this level of running & driving pep ready at your disposal would probably require anyone using this method to retain a stock pile of race gas cans in there garage.

Around here, race gas available at certain speed shops come in 5 gallon cans at what ever the particular prices is for that particular fuel grade.

Around here;
C9-5Gal (96 octane) @$88.99 = $17.80 per gallon
C12-5Gal @ $101 = $20.20
C14-5Gal @ $115 =$23.00
C16-5Gal @ $118 =23.60

Outright cost is a bit pricey. Race fuel is not so easily gotten at the pump around here. Why push it? If it makes things more complex and cost more, why bother?
It’s EZ to whittle something down until it makes sense or in your favor dollar and cents, but when it comes to actually doing it, is the hassle worth it?

I really don’t have $200.00 + in spare monies to spend and then store race fuel for the enjoyable ride even if rarely driven. In the end, it doesn’t make sense or cents to do.
