What do you think is the highest I should rev my motor? Balanced and blueprinted. ARP rodbolts. Shot-peened LS rods. I'm thinking 8k, but I am a little curious.

 

aww...come on, nothing? no responses?

 

iam feeling you can go to 8k with the set-up. i would upgrade my rods before you start to rev any higher than that you might want to do gsr girdle mod also it helps with at high rpm's

 

i was just curious. a local guy is running the exact same set up as me. im not sure if he has a block girdle or not, but he shifts at 8,500rpm and has 10k mi. with no problems. so what kind of numbers will i make?

 

8500, but dep on your cams, etc. could check the dyno which would be the best move....

 

Hey man...I rev mine up to 8500 with no problem and i have stock bottom end except for the civic type R pistons. I put my car on the dyno today just to see what kind of number. we didn't tune it or anything, we just put it on and run it to see and I got 168 whp and 119 lbs of torque. It's running really rich after 6000 rpm and my head is not port and polish so I start losing power after 8200 so it's no point for me to rev up any higher until i get a vtec controllers and tune it out. On a side note..We compare my number to a type R with header, cai, and exhaust I had the same amount of power he had, but from 0-6000 rpm I had 20 more lbs of torque than him...

 

Yeah I have my p28 set with a 8k revlimiter just to be safe since I didnt get a girdel. i will probably have it removed later on down the line once i get a girdle and some forged components

 

I have the ARP rod bolts, shot peened ls rods, computer balanced and blue printed, B16 cams, upgraded computer program, and i rev to 8500 all day long, 30,000 km on motor now, race as much as i can....never had a major problem.
If it is built right, you should be able to rev without concern.

 

I would say if you gots an internally stock GSR or B16 head and some rods you should be able to go rite up to a stock ECU's rev limiter 8,200. With some little other mods i would say you can go higher just make sure you upgrade ur valvetrain and get some cams that can generate power way up there. My buddies CRVTEC motor has JE 13.0:1 pistons, stock rods, and JUN type 3 cams. Before the motor blew when the cam shattered he reved it to 8,700 on each shift with a 9,500rpm rev limiter. I like those JUN's but i've seen many people that have broken them even with the JUN valvetrain made for them, he was running a Portflow setup.

 

damn never heard of broken cams man that sucks

 

i have the same set up on my ls and i shift at 8k and as of yet have had no problems.........as of yet
