How high to rev my chim

[fatboy chim]

I assume there is a rev limiter on my 4.0 but for good practice where should i draw the red line?

My rev limiter kicks and I mean kicks in literally at around 6000.

You'll find that the general consensus of opinion is that there is very little gained from taking the revs above 5000.

Routinely 4k or 4.5k. If you're pushing on you can take it up to 5k but don't do it on every single gear change. You get very little advantage going over 5k, if you're in a race and need every last bit of performance you can wring out of it, the optimum change up point is slightly over 5.5k although you get very little advantage from the last few hundred rpm. If you hold it over 5.5k you risk the lifters pumping up, also since you will have the preserpentine front end you'll find the wear on the distributor drive increases very quickly past this point. You should never deliberately take it over 6k for any reason, although mechnically it will survive about 6.5k before it goes bang the wear and tear increases dramatically at these revs.

I hardly ever rev over 4k on the road, on track i only rev the engine to 4500 .. as peter says there's very little point going higher ..

Mechanics accepted... but what about the noise? The scream as you approach 6000 rpm - it's music to my ears!

Thanks guys, didn't want to commit Chim abuse, as she's new its just a bit tempting to make her howl a little
