btw I did some rough estimates on running nitromethane as a fuel for GT-Rs. We'd need 8000cc injectors (or some equivalent), 16 Bosch 044 pumps, and although fuel costs would merely quintuple, I don't know what the mpg would be, so could be more.

But filling the cylinders with a 2:1 air/fuel ratio, that's a lot of fire to burn on each stroke!

Why isn't there some mad billionaire driving a street nitro car?? It's one of the first things I'd build if I ever won the lottery!!

Ever stood close to an idling nitro car ??? I wouldnt want to in traffic , plus the fumes are dangerous and the fuel washes any oil from the bores , motors dont last long on nitro

One of my mates had a Top fuel bike and went through a whole 45 (UK) gallon drum of fuel one weekend simply running the bike up in the pits , he never went down the track!!! One 54 US gallon drum of Nitro is close on £1600 inc tax nowadays

The reason the rules have been so restrictive is to limit the cars performance , there are tons of restrictions on both engines and blowers etc and even so the cars are hitting truly awesome speeds , recently there have been numerous fatalaties and serious accidents , there is a real move to slow the cars down , and racing over 1000ft instead of the full 1/4 (1320) is being seriously discussed

I think thats why Bob Feeler had so much trouble getting fuel of sufficient quantity and quality

Time to move on to 4 litre v8s, twin turbos and proper electronic fuel injection?
