Methanol

[T4TUFF]

I built my meth carbs on the two blowers, but where i live ya have trouble getting it some times. I can run petrol or meth with just a jet change!

so basically at the end of the day if youve been driving your meth car you need to drain the tank/cell and put a few litres of regular fuel in in it?

do you need to drain the fuel out to run meth again?

I'd run it with 10.5 : 1, you will be amazed by the mid-range torque increase.

I'll try to find some more info for you later, will post it here.

im only running like 7.5.:1 comp and since putn it on methanol the engine has come to life and runs cooler but only works well this low running boost
little different with EFI its just a quick computer chip change n switch on the second fuel pump so make sit easy to swap between fuels

I just drain the petrol out of cell n fill with meth, but start it with pet still in the lines n bowls, just so it starts easyer in the cold

this was an very good read, but it ****'s me too.
Now it's got me thinkin about methanol.

yeh its definitely tempting, need a big ass fuel cell so you can still take it on the odd cruise.

though one thing do people have problems with throttles gettin stuck on due to carbs/intakes freezing? like what happend to ucsmoke at summernats

[T4TUFF]

some days they freeze open
just sit on the limiter n steer it round the pad till the tyres pop
Just hit the kill swich when done.

lol just wondering how safe it is to actually go for the occasional streetcruise
