lol nah that manifold is some weird black plastic one... dont know its code...

this one has shortish/fat runners for top end power, but they curve around slightly and go into a extremely large plenum for low end torque... plut they have these sexy individual velocity stack trumpets on each runner...

ill get more pictures soon

driving an N/A 4 cylinder, I think it's important to get something out of the lower end. Good to see someone has the balls to experiment!

UPDATE PEOPLE!!!

so i was bored this afternoon, couldnt go out and detail Evelyn because im sunburnt lol so i started polishing up my RSP manifold, ive only done the velocity stacks so far, but ill eventually do the whole runners

PICTURES!!! YAY!!!

One stack done:


Close up:


Two stack done:

Wouldn't the RSP come pretty polished from the factory?

yeah, its made with the same casting technology as the nsx... as you can see by the too unfinished stacks theres no casting marks...

but i want those babies smoother than my pick up lines....

haha, I'd probably do the same thing. It wouldn't feel right driving it knowing you might be missing out on a tiny bit of power because you didn't bother doing something like that.

lol thanks buddy!

lol this power increase will alow me to eat maccas before i do my quater mile in apposed to after!

this afternoon ive been measuring up the differences between the RBC / RBB / RSP manifolds (length / width / volume)...

i wont be able to finish the comparison until i get the second half of my RSP. but i thought you might want to know early that the RBB has a total capacity of 3620cc compared to the RBCs 2800cc...

Fairly big difference! and ill tell you now, thats all in the runners... plenums are nearly the same size...

[integral90]

Doesn't that 3620cc vs 2800cc difference only matter if the car can suck in >2800cc in a certain amount of time?

Like if the 2800cc RBC could be refilled with air before the car could suck in 2800cc to the chambers wouldn't the difference be pointless?

lol i have no idea how different volume / length / width / etc effects how well a manifold works lol

but i do know that bigger plenums seem to give more power... lol

[Crapdaz]

lol thanks buddy!

ROOOOOFFLLLL!!!!!

good come back down here so you can take me for a spin!!!

Hey guys, as promised, here are the main differences betweem these three honda OEM manifolds, I do not have dyno proof of which manifold is better for what, but hopefully this info will help some of you out!

Please note I did try get these measurements as accurate as possible, but please do not crucify me if they differ slightly...
