ZX-10  04-05
(06 uses different stacks)





 

Billet Factory Pro design Velocity Stacks

Factory Pro V Stacks and BMC Race air filter and 45 minutes........

dealers!

Add 3 to 5 True hp to lower and upper midrange with these finely machined V Stacks.
This is big TRUE HP - not dynojet hp.

$249.95 inc. rubbers and billet stacks

zx10 04-05 only (not 06)
International orders will be billed additional $24 for shipping

Product designers:
Factory Pro designed these in just 8 different dyno runs - That's what you can do with the Factory Pro EC997 dyno and Marc Salvisberg designed Test Routines - and what you couldn't do without 'em.......
(also - note that this picture doesn't show the final stack sizes.)

Additional info: Running 4 short stacks (as the originals are on 1 and 4) are about 1-2 True HP better than the stock arrangement of stacks,  but aren't as good as the new Billet Factory Pro stack set - The Factory Pro stacks are about 3 True HP better than 4 short stacks and 4-5 better than the stock stack set -

Our testing was done with:
stock camshafts, stock pistons and stock valves and cylinder head and an aftermarket exhaust system.
and using the Factory Pro BMC RACE filter.

Why the Factory Pro BMC RACE filter?
The increased cylinder fill rate promoted by the Factory Pro Stacks is complimented by the filter.
The stacks and filter together, work better than the sum of the individual parts.

Additional mods suggested:
It appears that the mighty "10", especially with the V Stacks, could do with a bit of cam timing work. The EC997 dyno is displaying information that the intake cam could be advanced 2-4 degrees and pick up a fair amount of low-end snap and midrange punch. There is a distinct possibility that the maximum power could increase by 1% to 3%, also.

The shifting can also be improved - It's relatively notchy and stubborn, as compared to a "sweet' shifting bike - The EVO Shift STAR kit (below) will sweeten the clunkiness at low rpm in town and when "bangin' it" through the gears on the track - Virtually eliminates missed shifts, too!

Tuning? Don't "tune to an a/f ratio". It's guaranteed to lose power at the strip and street.
Factory Pro Tuning Centers with EC997 dynos NEVER tune to a magic 13.1:1 fictitious a/f ratio!
Or any other mythical marketing schemes.

Factory Pro Dyno Centers  F-USA HP leaders!
Tuning to Best Power
The way we were, the way we are, the way we will be.
Because we're right.

Dear Factory Pro,
I wish to thank you for the velocity stacks for the Kawasaki ZX10r.
On my retarded DJ dyno I measured a healthy 3 to 4 hp increase from 8500 to 11500 rpm.
My customer Danny Imberg remarked " can't get cheap horse power like this very often!"
Thank you Factory Pro.

 

Final output is 167 djhp, Factory pro velocity stacks, MHP full system, stock engine after 2 seasons racing!

 

Can't wait for you to do a R6 2006 ;)

Another ZX10. This one with Jardine slipon and stock air filter.

RED = Superflare Stacks, stock air filter

BLUE = stock stacks, stock air filter

"4 short Kawasaki stacks"
 

 BLUE line
stock 04/05 ZX10 stacks
(2 short outer stacks and 2 long inner stacks)

as compared to:

RED line
 4 short, stock ZX10 rubber velocity stacks

...........................

notes
The 4 short stock rubber stacks are very slightly better than stock (2 short, 2 long) rubber stacks and from user reports, the 4 short's  lose some lowend (although we didn't).

conclusion
4 short 04/05 zx10 stacks are as "wrong" as the stock 2 short and 2 long stock stacks
