Valver limiter..

[scubaman44]

Curious. My valver revs to just over 7000rpm and as far as I know its had nothin done to ecu etc. Do most rev this high? May be a silly one, so early apologies.

 

[Dan@SJM]

the rev counter isnt accurate.

I thought 7k was about the limit on them? I've seen about 7.2-7.3 but that was only a few times on track at FCS.

 

[BenR]

yup, 7-7.2k stock.

 

[scubaman44]

right. so when ya get cams etc and cars are remapped what is highest they generally raise it too?

 

[BenR]

you only raise the limit if the peak power position requires it to be raised.

 

[scubaman44]

ah ok. So when cams are fitted does the power come in at different points. I.e higher or lower in the band. I know it sounds stupid, was just under the impression that cams gave more top end, and that rev range increases as result.

 

[BenR]

Wilder cams, depending on design will increase peak power and push the point of peak power higher up. However going too wild will make your car on average slower as you will have less area under the curve to play with.

Just plonking in cams on a 1.8 does very little bar make it more peaky.
