Default picco xp help

I'm running a picco xp it's running good and fast but my temps are kind of on the high side. I have had picco motors in the past that like high temps like 250f 270f running 30% but i'm running 25% now and this motor don't make any real power unless it's about 260f. i'm running a #6 plug 25% fuel. who makes a picco header and gasket the xp's exhaust is smaller then all other motors.

Picco's need to run a bit hotter to make power.

Ofna has a Picco one piece pipe and so does Orion.

Not cheap though.

I have one brand new in box. Interested?

Default picco xp help

tone;

You are correct about the Picco Exhaust outlet being slightly smaller than everyone else.

So far the ONLY brand that I have found to fit is the Picco/Trinity brand headers.

You also might try one from Ofna/Picco, but I know the Standard rear exhaust type headers are larger and leak in a very short time.

All of the Picco's that I've owned ran best at about 260F, no matter what % of Nitro I used in them.
