Adding short velocity stacks to Gen3

[mark3evo]

@MikaSinteresting vid from MM 

 

with map and alien head exhaust   184 hp 110lbft

these CNC from cyprus are half the height of OEM  - look like a good mod for the Gen3

Short stacks lose 3-4 hp  at mid range but gains 18hp @ 11,000

another screen shot of DD3 (blue line) compared to GEN2 (green line) = more torque for Gen3 still and mid range power and strong top end

@MikaSdon't you wish your bikes could do the 'pops' and 'bangs' annoy your neighbours and the bears

That is a racers mod, not for the street rider

yes it is mentions top speed, drag racing 

he says.. as the bike already will lift the front wheel its good to lose a few hp mid range for the improved 15hp at top end

That is also the case with big blocks,

few times talking about the power curve and why is it weaker at lower revs using bigger cams,

our tuner reminds that you dont need the torque at low revs, it only creates problems for handling

Except that it's a gen 3 that's the topic here, a bike with electoniky things to control unwanted wheelies etc

@JOHN-DYNOSTAR IIRC, the 1000cc gsxr has a ball bearing rotating timing adjuster thingy slapped on the side of the engine. Could this arrangement be moved to the busa?

So, you need a strong bottom range that you have something to cut down with the electronics ?

i'm sure it could but i think Suzuki dont have enough  R&D resources cash etc

but maybe the relatively low rpm range 3k to 11k is not worth it 

as gixers have 3k to 14k range makes more sense
