Default 40% nitro fuel

When using 40% nitro fuel do you have to change head clearance. If you do, what mm do you change to.

Thank you,

There is no set amount you change. Especially when we dont know what engine its for....but there is a guide to the amount you might want to change.

But 40% , wow , thats some potent stuff. Most people around here run 30% if not less.

All I know is that you need to run cooler glow plug for higher nitro fuel.

I meant to edit my post.

Going higher nitro % , you will want to add more shims. Just for reference.

Lets say you have .3 shims for stock setting and reccomended %20 from your manual.

Youll want to add at least .1 shims for every 10% nitro.

If it was .3 , I would now go at least .6 and see how it tunes out.

Usually adding .003 to .005 in shims will work, however watch your plugs, If you start hurting them, then add a little more shim.
40% tends to cause you to change rods more often and you'll need to weigh the minimal advantage to using 40% against higher maintenance costs.

nitro must be cheap over there

if you can't get power out of 20 to 30%nitro then your tune/clutch/pipe must be wrong!

You're partially correct, everything else needs to be right, but we were only talking about nitro percentage vs. deck height.
Frankly, 40% adds a little speed at the end of the straight and a little snap off the corners and I will only use at at a major race and then most of the advantage is physcological.
