ok i have made my F8 , what is the best thing to do , run it with 150psi compression without timming key or 130 psi with 2 degre key ? I want your opinion !!! remember it need to be trailable and i also have single monster pipe for 8300 rpm. do you think heat could be a factor ?

i assume its carbed?

as long as you can run premium gas i would think you would be able to run 150 and the key together...

otherwise probly 130 and no key and run whatever gas you want...

I am not going to say that I am a tunner but water temp is the key. If you can keep your sled cool in all your trailing you can run more pressure. If it was me I would run lower comprestion, and the key if carbed. Carbed sleds will take more timing easier, BUT that pipe running higher into the rpm's the timing key would not be much of an advantage there. The key helps out the bottem end. Higher comprestion will shine sping higher in the rpm's.

You need to figure out what combo you want top end or bottem end.

Just my thoughts......Don.
