whats the highest rev potential on a stock B18C1 bottom end?

 

if the motor is stock then 8400. if its a built motor or Turbo then it all depends on where your power band starts to drop off. And the only way you would find that out is dyno tune! if seen people raise their redline to 10,000rpm on a stock gsr motor, but theres really no point.

 

cams, head flow, intake manifold, and header all play a role in how high you can make power.

without knowing the specs on any of these, it's pointless to speculate. go right ahead and rev it to 10k. but your pistons and valves are going to say hello to each other.

 

Ah! I have thought of this. I was trying to find out if you had a topend built for 9500 can the stock bottom end hold up? what head parts would get me there anyway?

 

Probably not for very long.

I would be just as worried about the accuracy of a distributor type ignition revving that high.

Focus on power goals instead of how high you can rev. High revs put an incredible amount of tensile stress on the rotating assembly, so if you don't have to rev to the moon to make the power you want, it will be better for the long-term reliability of the motor.

 

not very many cams are going to keep making power that high and the ones that do require an insane amount of compression. at those rpms with a stock block, the rod bolts are going to stretch.

 

oh well. just thought the topend would be cool to have. so what hp numbers can the stock bottom end hold without bearing/rod/journal damage?

 

sticking with na, i'd be more worried about rpms than hp doing damage. if this were boosted hp would be the determining factor.

 

Sorry. It would be n/a. call me old fashioned but I like the sound of a performance motor on its own.
