1700 Super Sprint redline? Is there supposed to be a rev limiter?

[pethier]

There is no actual red line on my tachometer.

 

I have not noticed a rev limiter kick in.

 

(I test drove a Rover K Caterham and there was a hard rev limiter at 7,000.)

 

I don't expect a 1700 crossflow to rev to 8500 like my Elise did.  And I don't want to over-rev it either.

 

Anyone have any guidance for me?

It is tuned to make peak hp at 6000, but that is about as high as I would ever consider taking it, considering it is not OHC. I'd probably detune with a less radical cam and softer springs for longevity with pushrods and low-zinc oil.

standard Kent engine crank should not exceed 7K RPM.

Yes, I would put on a rev limiter.

I now suspect there is a 7,000 limiter.  I think I hit it in 2nd gear at an autocross.
