Tis I, whats the problem sir?

Hi Sunoco,

I have a engine that I am not allowed to advance the ign timing on

what can i do to reduce the octane and make it burn quicker ?

can anything be done to the fuel to make more power ?

[sunoco69]

Can you increase compression ratio? Is this a race car and if so what do the regs say?

If allowed you could try a high oxygen fuel which might allow you to alter the mixture and/or compression ratio.

If all you can do is mess with the fuel then you really need a light fast burning fuel and the only way you will get that is race fuel. Sadly not a chap option.

i am not allowed to alter the compression ratio and they do spot check cylinder ccs from time to time

the way to make power is to advance the ign - but it is not allowed !

i did some research some time back about heptane

http://en.wikipedia.org/wiki/Heptane

it does appear to be what i am after - but have never tried it before and have no experience

what type of race fuel do i need

[sunoco69]

The fuel may depend on your championship regs. What series are you racing in?

Might be miles off the mark but if this is for karting then any real / major competitions you will be made to use controlled fuel. Your also running the risk of scrutineers pulling your fuel for tests if your blasting past people up the straight.

I'm sure you said you'd bought your son a cadet kart. Apologies if it's unrelated, just seen it happen quite often in the past.

If you drop the octane do you not just increase the chanse of dept.? It sounds like you really need a fuel that has a quicker burn rate and maybe more octane (to provent dept.)....
