Ok guys im a little confused, i know the AP1 can rev up to 9,000. but im here checking the specifics and it says 240 hp @ 8,300.... if our peak power is reached at 8,300 why do you guys take it all the way to 9000? wouldnt that just waste time?

 

Yeah, but think about this.
If you shift at 8300, your next gear will start at a lower rpm than shifting at 9k.

If you shift at 8300 it would drop you well under VTEC for the next gear and consequently make you slower.

With the stock gear ratios, shifting at 9k is necessary for you to stay in the powerband (VTEC).

 

think area under the curve when looking at a HP graph.
You want to maximize area under the curve and shifting at 8300 will not achieve that.....i think it'll even drop you out of VTEC in some gears.

 

plus you make more power from 8300-9000rpms then you do from 6000-6700 rpms, so even though you passed peak horsepower your still making good power in that range.

 

it will not drop you out of VtaK.

 

To elaborate on what nearwater4me said...

By shifting at 9,000rpm the engine will still be in VTEC range when you land in the next gear. This is important if you are trying to accelerate as fast as possible. (I assume you know what VTEC is and why this is important)

Also, even though peak power is made at 8,300rpm there is still a good bit of "ooomph" occuring between 8,301-9,000. Its not like the power falls off completely after 8,300 is reached.

yeah guys i got it now, thanks

 

And.. that is why automatic is SLOWER for shifting at exact point

 

Yeah that's why didn't get the automatic S2K.

Plus it was $1K more expensive
