I've heard of b18's reaching 9,000 rpms. If I balance the crank, do I have to balance the camshafts or can I balance them? I also have JE 10.5:1 pistons and Eagle rods to go with it. Well they be able to handle the stress? thanks
9,000 rpm
- Thread starter jason_guy_yeah
- Start date
making power with more boost is safer than with more rpm. boost puts more compression force on the rod, which is what its meant to take. rpm puts tension on the rod bolts, which are far weaker.
hmmm....didn't know that. So, with the current set up(not balancing the crank then). What rpm's can I reach?
there is no reason on reving so high if the motor is not going to make anymore power at high rpms. Only a proper tune of the car will you know whats the highest you can rev without loosing power.jason_guy_yeah said:
depending on the type of cams I get and/or how much the cams get adjusted; will move the power curve.
so, would anybody know if I can reach 9000 rpms?
dude, you can rev to 9k all day long... its pointless unless you built it to make power up that high anyways.jason_guy_yeah said:
you will need to balance the entire bottom end, lighten the rotational mass, and lighten the valvetrain as well. you will need a big cam, and a really good tune. hope that answers your
my buddys integra revs to 12,000. it stops making power at around 10,500 rpm. but its a amazingly built motor.
rotational mass?? and lightening the valvetrain, you mean lightening the cams?sohclubkid said:dude, you can rev to 9k all day long... its pointless unless you built it to make power up that high anyways.

You are correct on balancing the bottom end and lighten the rotationsl mass (ie. flywheel, crank pulley) but this is not a must. And i think you ment to say strengthn the valvetrain and some higher lift cams. And do make sure you get a great tune. And what is the comprassion ratio you are heading for?sohclubkid said:dude, you can rev to 9k all day long... its pointless unless you built it to make power up that high anyways.

rotational mass... like lightweight flywheel and such. and cams are fine like they are, they will snap usually if you lighten them, so i dont reccomend that. titanium valves (or sodium filled i believe), retainers, and upgraded valvesprings. those are things to look into.jason_guy_yeah said:rotational mass?? and lightening the valvetrain, you mean lightening the cams?
cool, thanks guys
if u wanna rev high you have to build your head up.......otherwise ur float ur valves....
because I can. So, what do I need to do to make this happen?
no dude!, I'm not going to do this on a stock motor. I'm asking what other internals/balancing I need to do. Oh, yeah, I also have crower springs.
