Man this engine flys in my DM1.Got 4 tanks through it started leaning it out temps around 210 its a rocket.With a 053 pipe.I have a 086 also to try.

Question can I buy a turbo button for this engine? Its is non turbo now?

Also has two head shims,can I remove one after breakin? Running Byrons 30%

Thanks Pete

I would leave the shims alone for 30%.

The 086 should give you a bit more top end, as if you needed it

Thanks!

Do you know about the turbo plug button?

here is the turbo button part# OFN51536 (nitrohouse carrys it)
use the same shims when swapping out.
