Dang my friend your on a roll.RC46, apparently I didn't give the "wanted" answer so I am wrong lol everyone wants to compare dyno crap data without the airspeed to make the ram air FUNCTION. It will not work with the bike stationary on a dyno. If anything I can see it hurting hp with the added twists and turns of the duct work.
Partsguy, you say your carbie was always about 3mph slower through the trap. You can bang on the stationary dyno drum all day long, doesn't make it fact. You say the HEAVIER FI Bird (we can all agree the FI was heavier right?) was always 3mph faster through the traps.... what does it take to get a heavier vehicle to go faster in a given distance?....... MORE POWER. If you raced I assume you understand that it would take a notable increase in power for a heavier machine to not only catch up to but surpass a lighter, identical machine. I also assume you understand that the carbie has slightly more rotating mass (clutch plates) which would store more energy for launch. true it's only a few ounces but at 5,6 or 7000 rpm launch it's an advantage none the less, especially on a lighter bike. You can't argue with physics. While on physics let me bring up another advantage the carbie has off the line, the CV carbs. They will only open as much as the engine has demand for thus keeping intake velocity higher than a FI Bird (does not apply to WOT of course and by that I mean the slides not your wrist). Air has mass and we all know that objects in motion tend to stay in motion unless acted on by an outside force. This is a little tricky for me to explain but I'm going to try. With a CV carb the intake velocity stays high because the path is restricted. What this does is that when the intake valve opens air/ fuel is sucked into the engine and the entire mass of air in the air box begins to move. when the intake valve closes that mass continues to move and piles up against the valve creating pressure. Over a certain rpm this pressure does not have time to completely dissipate as a revision pulse and is now a pressurized "puff" that gives the intake charge a head start if you will on it's way into the cylinder. On the FI bikes you are in direct control of the throttle, you open it up at launch and the throttle bodies are capable of providing much more flow than required and the intake velocity drops. Now you don't have that little "puff" of stored energy in the moving mass of the incoming air/fuel mixture. At 5000rpm the intake valve opens just over 41 times per second. That is 164 times per second for all 4 cylinders now assume you pack in an extra 2cc of fuel air mixture per opening because you have a higher intake velocity. That is 328cc per second more fuel and air you are getting into the cylinders. Each cylinder is only 284.25cc. The engine is 1137cc x 41 (intake strokes per second @ 5000rpm)=46,617cc (@100% efficiency, never gonna happen). Having CV cabs should mathematically give just under 1% better volumetric efficiency, another slight advantage over FI off the line.
So now you have more rotating mass, less total weight and better volumetric efficiency at launch. How is it that the FI Bird is able to be faster through the traps? MORE POWER that you don't see on a dyno but you do have in the real world. You are highly discounting the pressure wave that is in front of the Bird at 185mph (where the 164 gross hp comes from), this is pressure that is fed into the engine at speed, it's a free, low boost turbo that you can't measure on a dyno without a wind tunnel and I would not put it past honda to have used a dyno during wind tunnel testing of the Bird.
I have been on my both of my bikes, carbie and FI with a damn good friend on the other. 0-100, carbie wins hands down regardless of rider. after 100 the FI walks away from the carbie (even with 90k more miles on the clock and without the PC) doesn't matter who rides it. btw, no one claimed 164hp at the wheel on any stock Bird, Honda numbers are gross not net.
Again I must ask... Really your a Peace Officer? lol! just kidding but U no that's just me.
Cheers, STex out
