Thread: RPM limit

Hi, how much rpm can i rev securely in my Stock 20VE, i heard 7800 and 8200, but im not sure, im going to buy Calum, Thanks!!

Careful, I'm sure Calum is VERY expensive.

There is no point in taking it past 8k with stock cams.

it's just a question, i just want to know the engine limits

I wasn't laughing at your question per say. We were pokin fun because you said you wanted to buy Calum, as in the person not a Calum ecu

I know you are not laughing.

I'm going to buy calum because im going to do a lot of changes in a future, like maf and injectors, but not in this moment.... in this moment i'm with 333cc and stock DE ecu, but my MPG are not good, my spakrplugs are dark, i need tune up my ecu.

You sure want Calum badly, huh?

eeeh, yep jaja

Someone answer his question (I'm interested too). When do valves start floating with stock cams/springs? Or is there a different reason not to rev it past xxxx rpm?

Power pretty much takes a nose dive after 7200 with most setup's with stock cams, that's why I was saying there is really no point in taking it higher than 8k. I think with 20ve cams the valves float around 8200-8300. 16ve cams start floating just a little bit higher than the 20ve, the 16ve cams have more duration, but about the same lift.
