What ddgonzal says is right.It is the ability to raise the compression without detonation that yields the increase in power.

Generally the engine will run cooler which may be a real benefit.

Methanol has an octane rating of about 108 . As for racing fuel that will depend on who supplies it so you need to check the Octane rating with them. You should also realise that LPG has an octane rating of around 112. A purpose built dedicated gas only engine may be worth investigating.

Methanol is alcohol and requires approximately twice the fuel flow. So it requires larger fuel lines, fuel pump and modified carburetor.

It won't make any more HP than gasoline. It allows you to run more compression, but so does racing gasoline without the need for extensive fuel delivery modifications.

Fast a12 engines are pretty unique in their own rights as most upgrade to a14s/a15s as its the most simple way to up the a-series power.A worked a12 sounds great and revs hard.

Depending on what your after,if not fussy,try and minimize any weight possible while running the a12.smaller,lighter battery,fibreglass or carbon bonnet and guards ,no carpet and sound deadener, etc will not be comfy but should be fun.also a good clutch and a lighter flywheel.

Some forum members have modified a series engines and would offer better advice in relation to running methanol i.e Compression,metal head gaskets and the sort.Personally, i wouldn't run methanol on street and would first find out if its legal to use it in your state.
From what ive read on this site,very modified a series are not too street friendly.

if your after bang for buck, your better off with a good affordable turbo engine.Modified a-series gear can easily top up the costs for a turbo engine conversion with slight power increases for a lot of money spent.

and if you don't mind me asking, what bits do u have for your a-series.im very interested with a series go fast bits.pm me if you want.

cheers

Yeah ...I'm just stuck at the moment with what to do. I've got a lot of go fast bits for the a12 but wondering if it will even make 100hp ..
I run one of my bikes on methanol and it goes like a rocket ...it would be nice if I could make the old ute do the same thing Hahahah :P

hey speedaddic,
if your after bang for buck, then turbo engines will be your best bet.Id say along lines of ca18det.Ofcourse check legality of any engine conversion before spending heaps just to find out you can't register the car if thats what ur intentions are.
im hoping to modify an a12 and run it in the future.Id say build a crazy a12 mate.im not sure of driving a methanol a12 though and how it would respond in the street.

Methanol a12 ? Is it worth the effort or should I stop wasting time and money and just do an engine conversion to something like a 4age ?
Wondering which one will be better bang for buck ...basically
Just need some direction ...any help will be appreciated :)
