I posted a lot of threads about hyper engines but since most of you here have past through hyper engines on your way to the top class i would like to know a few things(upgrades) that will give this hyper a new "name"(more competitive)!!

I know about the carb on the H8p so the O.S. 20E carb from the RG engine is the BEST!!
-what about a head that will lower those high temps and will it work as told...?
-which pipe will work best on this engine and will give power in all rpms...?
-which air filter will fit the hypers pipe and is best for off road...?(mines needs cleaning every time)

Can you post the fuel economy on these engines...?
Mine goes for around 8-9 mins,rich, and temps around 230-240(70 ambient).
