No_Fear said:stock is 8400 if i could, i would give it another 200rpm
blinx9900 said:good news for you: while honda does advertise it as 8400 aftermarket tachometers as well as the apexi vtec afc have all confirmed it is actually 8600id say it can safely rev to 9500 with upgraded cams vavle springs and retainers. without that you can still rev but your not making power.
No_Fear said:thats nice if all ek9s are 8600.i dont trust the stock needle goes around 8900 sure must have a % mistake.
SpoonCTR said:9000 RPM at the cluster = ?? 8600 ?
No_Fear said:all ek9s i've seen, rev to around 8900 with stock ecu. so must have around 200rpm loss.
rvm said:well i have one doubt.
I have a chipped p28 ecu, with a rev limit se to 9000 RPM.
I see that my car revs up to 9000 RPM in my gauge cluster. And after that the ecu automatically stops reving.
Maybe the gauge cluster doesnlt have any RPM "loss"
Interesting huh?![]()
blinx9900 said:as i mentioned the only accurate one i ever saw was actually an EK9 cluster, i dont know if they are all that accurate or if yours is just good, but either way thats good to hear. my em1 cluster is way off. im jealouswant to trade?

Andynista said:RPM limits are not only conditioned by the valvetrain, there are other rotating parts in an engine like water and oil pump that suffer tremendous stress at high revs, and when they fail, noone looks at them its the valvetrain that takes the blame....... I say be safe and keep it around 8500-8700 max. Happy reving..... hahahahaha
