Has anyone actually ordered from RC? And for those of you who have gone through the math on their site www.rceng.com what are you coming up with for sizes? 310cc seems to be too small for a TC application using their math. 370cc looks better but is a little on the large side. Im talking about 190-200 crank. I'm about to start making progress again and I dont want to spend $400 bux for the wrong stuff.

 

well RRM boosts 6psi on stock injectors and they are fine

most upgrade to 300-330cc i believe.

but if u only wanna hit 190-200 at the CRANK u dont need injectors...RRM stage 1 is easily that at the crank...non-IC on an auto

 

Would 300-330 benefit NA engines? I am hearing that I should get larger valves if I want to really find some hp out of my car. Any idea how to go about doing that?

 

i would assume better fuel management would give you more HP, allowing more fuel to flow freely...like oversized injectors/pump only working at 40% instead of the stockers workin at 80%...?? maybe

could always raise compression and get a cam gear as well, dunno about valves...that'd be tough to get bigger valves...u gotta find them..than port the valve openings EXACTLY to match the newer valves...might make the head to weak between valves though so i dunno? or do we only got 2valves/cylinder??
