You can make more power with race gas NA, but there are other reasons to run alcohol. All depends on what is important to you.

Alcohol is less expensive than race gas even though you use twice as much so that is one factor. It also runs cooler so if you race in hot weather you might be able to save money/weight on things like the radiator and water pump and stuff like that. But alcohol requires extra maintenance on the fuel system so it takes more time and can cost more to replace parts and such.

Be prepared,oil changes and other maintaince can be costly.

I'm also very interested in understanding why race gas would improve performance compared to alcohol??

I have a buddy that I race with he has a 588 B1 M/C on Methenol. I have a 572 B1 on C14. We race all the same races together. This year he used 74 gal of fuel at 3.33 a gal I used 54 gal of fuel at 12.29 a gal. His car runs low 4.60's my car runs high 4.70's. He changed his oil one time this year and has had zero fuel system problems. Needless to say I am changing to methenol next year. I think the key is in the fuel delivery. If you are fat it is going to give you trouble.

Been following a number of posts that have been indicating that alcohol is not the way to go with larger CID NA combination. I am curious as to the specific reasons why gas would be preferable outside of the maintenance/start up/cold weather challenges associated with running methanol in a 15:1 combination. Yet to get my combination down the track but it is a 572 B1 15:1 EFI combo running methanol. I kind of liked the idea of running cooler and the consistency that methanol offers but I am open to understand any reasons why I might expect improved performance from gas.

If your asking about a N/A combination I would think that the BTU per gallon makes the differences in HP on the dyno. I did a dyno test on a low compression motor, 10.78 to 1 comp. ratio pump gas 518 C.I. motor, and saw that both race gas and pump gas made more HP than E85 jetted for best performance, the E85 did make more torque with a little less HP. I would assumed, based on Methanol having around 85,000 BTU per gallon compared to 83,000 BTU for Ethanol that straight Methanol might almost make as much or maybe a tiny bit more HP than race gas and the E 85 does I run the new car on pump E85 and I like it, that motor(505 C.I. bracket motor) has a little more compression than the pump gas motor did The one thing I don't like about running straight Methanol is the stinking fumes and watery eyes

thanks for the feedback, there are definetly some differnt views on this one, going to try the methanol set up next spring and will report back

If you take the BTUs of alcohol per gallon, compare it to race gas BTUs, and take into account that you need more gallons of alcohol, you will see that alcohol will give you more power.
As always, your engine needs to be set up for the proper air/fuel mixture.

Oil lasts longer than in a gas motor once you understand how to run Methanol. Run the motor HOT. That is where it wants to run best anyway. I stage at 185, and let the motor heat up to 210 on the return road. The oil stays clear, no contamination from water or fuel, and especially no contamination from gasoline. The engine temp is easily managed. Lean out the motor for warm up, and because you run it hot hot lapping it isn't a problem. At the end of the day, be sure there is no fuel lingering in the cylinders. I have an injector, and I need to crank it with the fuel shut off a couple of times while the lines drain out through the nozzles. It can take twenty to thirty seconds before it all runs out.
I was told by my first engine builder that there is a cross over point with alky Vs gas. He claimed 7500 rpm or there abouts. Seeing the results of those that switch from gas to alky, I can buy into that. So is race gas a better fuel? Not in my mind. To get max Hp you need the best gas, and that costs a lot. If you are willing to run E85, it will handle up to around 13/1 compression, makes similar power to gas,(maybe a touch more) and is dirt cheap by comparison. Methanol will work well up to about 15.25 to 15.5 to 1. After that the tuneup needed starts taking power away and parts start getting hurt more often.

the oil in mine if anything looks clearer on alcohol than race fuel.The 15-1-15.5 CR is perfect.I run only the very best alcohol in my engines VP M1 it is a little higher than the standard but still in the $170-$180 range.A while back we bought 5 drums of VP M1 @ $160 each,that might be the better way to buy it.
