He wants to run Pink Power 16% or 25% available from Elite Models in Mansfield. It is by far the best fuel in the UK.

he is going to use byron race fuel ..... but what % should he use to run his engine in 16% or 25%

go for 25% all the way.......

thefuzzclub

for bashing 16% will do. but if your friend is racing i would go for 25% to maximize speed and punch of 5port nova engine.

i think it is best to use the same nitro content for break-in as you will be using after break-in

I second that of jason102276.
I have always used the same fuel
with the same Nitro Content when
breaking in a motor and when actually
running it.

tennessee

I do agree

O'DONNEL 20% or 30%

jason102276

tennessee have you ever tried fantom fuel?

i do like the byrons but someone i know can give me a little better deal on fantom fuel

tennessee

No I have not.

im gettin the same engine too soon.. is it ok to break in th engine on 25%????

tennessee

Break it in with the same fuel that you intend on using to race with

supra528

k.. so i dont need to make any changes wit the head shims or anything???

tennessee

Not if you're using 20%

If you use 30% you may have to goto a colder plug

If you use 30% you may have to add a shim .010
