Explain this one to me. All b series vtec heads make power to at least 8k in stock form.

 

show me dyno a dyno graph of an ls/vtec making power to 8kh:

 

Your wish is my command. It is really hard to find a dyno graph of a stock lsvtec, but I think this will do since they are still running OEM cams and non-ported heads:

CTR cams, mild build: http://forums.evans-tuning.com/viewt...ghlight=lsvtec

B16 cams, 300whp setup: http://forums.evans-tuning.com/viewt...highlight=vtec

Stock LS vtec, custom kit, shitty tune: http://www.honda-tech.com/zerothread?id=484677

 

The first two dont support your theory of them making power over 8k, the first one power peaks just after 7500, flattens out and is out by 8k, this is maybe the closest to supporting your theory, the second one, power is flat from 7k on, and the third one, alright you get that one, but it also has a turbo

 

It made sense when I said it, but even looking at my dyno graph, it stops making power at 7500 rpm. Strange they would have it rev out to 8k, but stop making power 500 rpm before that.

I guess I'll give you that one. h:

 

Doesn't matter if it stops making power at 7500, you should also be using gear ratio to dictate the shift point for maximum acceleration.

Look at it this way (on the CTR build, as that's NA) if he goes 700rpm past peak, he making within 5-10hp of the peak. If you push the start of the next gear from say 5000 to 5700rpm, it starts with an extra 35-40hp. That will help quite a bit in acceleration.

It's called overrev, and it's valued commodity, especially in sport bikes.
