My experience, as a pump gas racer, watching the alky guys goof around with that fuel and the problems they have, and breaking out the fuel testers and such...Ain't worth it. All my stuff runs on the same fuel. The ATV, the generator, and the race car...can't beat that. And I only need to take 10g for a weekend of racing vs an entire drum and all the pumps and BS. We won the season on E10 93...I won three big races that year, and anything can be made consistent with time and good parts...
I am simple, and plenty of MBB combo's will make more than enough HP to kill a stock block on pump gas with today's heads. If you have a race fuel motor already, we have found Snow's water injection to work really well on 93 and 14:1...I would go that route long before I went to alky...And we have never had any cooling issues on pump, even round robin.
Thanks for the reply!
The last engine would run on pump, 10:1 comp. with 280@ .050 cam. The po mixed 50/50. I drained the cell and filled it with 93. I've heard many say Race gas is more consistent. I didn't see any change in performance or consistency. 5 gal. fuel cell burnt about a quart a pass. I just topped it off after every pass and mixed the fuel I bought with what was left over in the can from the previous week.
The car has a good cooling system and a alternator. I can sit on the line for a long time without the temp. rising.
The new engine will be a pump gas deal. If for some reason I can't find the consistency I'm looking for I may make the switch.
