Hey all I was wanting to know what would be the safest maximum rpms for my motor? Here are the specs:
B20 block
11.5:1 wiseco pistons
eagle rods
Stock b20 crank
B16 head
S2 tuner stage 2 cams
S2 valves
S2 springs
S2 retainers
S2 cam gears

Highest I've pulled it is 8500, car was tuned to 8000

RASE

About 400 rpm past the point of peak HP. So get it on the dyno and find out where that is, first. Theres no reason to go any higher than that unless your in 4th through the traps or on a road course and need to hold a gear a little longer than normal.

Id say about 18,000

Call me crazy but my gut tells me not to listen to you... lol

You'll have no need to rev any higher then 8800, as the s2s2's start to fall off.

A picture of your dyno will tell us what to tell you. The dyno graph can tell you. You can rev it to the moon..........if you want....

Do you have data logging? Rev it until it floats a valve or something lets go. Record data, rebuild, now you have your absolute max lol.
