Re: Driveability of high compression cars
With the correct cam you can bleed off enough cylinder pressure to help with some low rpm detonation. Also, thermal barrier coating can help ( ie, keep the charge cool ).

Re: Driveability of high compression cars
In the old days I ALWAYS ran a rough mix of 60/40 Unleaded pump/AV gas...Maybe a straight 12 gallons of AV gas Sat night...off to the drags Sun morn...[12:1 comp] Always ran purrrfect! Last time I ran AV gas was two summers ago ..same mix [11:1 compression] very good!
But now I'm too lazy..the truck drops off the drum of VP 4:1 [pump/av]in the L-78 1:2[pump/av] in the L-88[ or straight if it's off to the drags... The 496'' in the grocery getter is 2005 gas station friendly

Re: Driveability of high compression cars
[ QUOTE ]
I have been lazy!  [/ QUOTE ] Where do you guys store these drums of VP fuel? Is it safe to keep it around your house? I have a feeling the wife would object to my keeping this stuff anywhere near our home. Is it even legal to maintain this amount of race fuel in a residential area? Just curious since it seems to be a common thing to do with you guys who own high compression cars.

Re: Driveability of high compression cars
I store mine right in the garage. Three gallons of lawnmower fuel will just as easily burn down the house. With a little common sense, its safe to keep a drum in the garage.

Re: Driveability of high compression cars
The 427 Camaro has always (since 84) run on straight AV fuel with a lead additive. At 12.5 to 1 with open chamber heads, it runs great with temps in the 170-195 range. It does "barf" throught to overflow though in the heat of summer(???) The 427 Impala has just been put on a 50/50 diet the same way. At 10 to 1 with oval heads, I don't think I'll have any problems. Have a Good Thanksgiving!
