Trottle body GSXR K7 / K8 for Hayabusa gen 1
« on: October 02, 2013, 04:58:51 PM »
I'm from Argentina and I have a query, depending on your experience and knowledge

I have a Suzuki Hayabusa 1300 model 2006, equipped with: - Power to commander III + Power ignition + Hub + airbox modified + Air Filter K&N + - Exhaust complete Muzzys (4 to 1) + - Velocity stacks, Race (all short, 41 mm) + Wiseco Piston kit stock bore 81mm 13.1 to 1 + Elimination counter balancer + Intake cam on the exhaust (2 cams intake OEM) + cam sprocket adjustable + Scoop ram air + seal, ram air tubes (Carpenter) + chain EK 520 zzz + ECU Flash
Nowadays it got 206 HP in the rear Wheel with final speed in 335 kmh (210 mph).

My question -->
I would like to fit a 48 or 50 mm diam. throttle bodie. I’m looking for power in high Revs (from more 8000 RPM)
What do you suggest? And how many HP could I win with this modification ?

Throttle bodies in study

a) Trottle bodies Suzuki 1000 K7 / K8 ?
b) Trottle bodies Kawasaki zx-10r 2011/13 ?
c) Others

Any suggestion to make?

Thank you very much

I don't think any of those throttle bodies will fit. Also I find it hard to believe that your making .206hp and going 210 mph basically with no cams, no headwork , and just heavier then stock pistons, and you didn't mention what gas. Just can't see it. What I suggest is headwork,cams, and a bigger piston kit.

I think he was on one of those dynos that also tell you mph and ¼ ET, usually inside a trailer.
That’s how I’m reading it at least.
Those dynos are very optimistic.

Pretty sure he means not a restricted length of track, ultimate top speed. Having said that I think a dyno told him 210 mph.
