How High Will It Rev, Before It Goes ?

[Doogs]

yeah, fair enough

you are spot on, if i do it, i might as well do it all properly, as it would just be a pain to

have to fix it all up later ! :)

With the right cam, 4-7K is where it should operate. We've all revved the date out of one of these things for giggles, but thats where you should be looking.

 

Hehehehe......brings to mind a certain incident where a certain someone revved the crapper out of his newishly built 5k, getting to about 8000rpm and then having a slight brainfart and deciding to drop the clutch....much giggling and metal gears going "bang" insued.....it was only the diff but taught me a lesson....lol

 

On topic, i had my 5k balanced and the flywheel is still original.....i also had the harmonic balancer (only on the 5K) rebuilt. It sees 6500rpm on a daily basis, at least once to 8000rpm each week just for shits and giggles.

Just build your motor to make peak HP at 7500 or lower and save your $$$.

 

A stock bottom end is good for 8 grand (or more) :)

 

Biggest weakness in a high revving K motor is piston ring groove wear.
