I know Steve is right. I wasn't looking for RPM HP in the first place, like you said the rods can't take it. Torque is simple its Force times the perpendicular distance. I'm not going to stroke it, so I have to add more force to combustion, ie increasing volumetric efficiency and flow quality at rated RPM. Yeah, to the most perfect job I would have to model the whole intake system and do a computational fluid dynamics analysis on it, look at reynold's #'s, boundry layers, etc. I think if I clean up some casting defects and gasket match and a few other things, the cylinder will fill more at that RPM. I'm not hogging out the ports and/or bowls so velocity decrease will not be an issue. More air/fuel in the combustion chamber equals more torque right? If not, how can you make more torque with less air if the air/fuel mix is what is responsible for creating the force on the pistion driving it down? Correct me if I am wrong, I am asking. I don't get to learn much about engine stuff being a ME student, just doing stress analysis and the sort, I want to learn all that I can. Putting an EFI system off a V8 into an I4 sounds pretty neat, you are close in displacement to the 302, won't he have to add a ton of sensors like crank position, knock, intake temp, MAF, etc? Sounds like a cool project. Make sure to tune the intake runners to take 100% advantage of the EFI, with EFI you can make all kinds of silly bends you normally can't with a carbed engine. Send me some pics when its done.
Oh yeah I go to RIT. I put my website below, there are links to the school and other things in it.
