Nah, I was looking at the ram air tubes thinking there was something special about them... And btw I just saw some pics of your bike... That thing is

Thanks, and actually those air tubes or something similar to this http://www.oppracing.com/product_dis...airducts-pair/ will give you some extra HP due to a better flow of air coming in, less restrictive.

To add to that, the bigger the temp difference between charge temp and ignition temp is, the more HP you are making, no matter what is happening with anything else.

Ah well I guess I'll never know.

What do y'all think about Hayes' bike vs Young's? Does the R1 make more juice?
Well he is kicking Blake's Ass in the curves and in the straights so I would say Yes!

I have a pm from someone who ran AMA SBK and now works for a vendor here and he said most of the hp claims are exagerated greatly. He said for certain that on a good day Hayes' bike made low to mid 180's. He wasn't running quite as much kit and he was down about 5 hp at upper 170's. Read the AMA rulebook and you'll see how restrictive it is. You can't really even touch the bottom end, ie. oem pistons, rods and crank. Top end leaves a little room to work but they are still required to rin the stock airbox. WSBK is a whole different game as far as engine mods. I wouldn't believe too many claims of 190+hp from anyone. Tim Radley, a noted engine builder in the UK will tell ou how much work is necessary to make big hp from the x-plane. Eric Dorn of EDR Performance will tell you the same thing. It will be interesting to see how much hp the gent in the 09-up Performance Group thread will make in his build. It's loaded with YEC kit parts and hi comp pistons...

My buddy sent me the contact info for an engine builder who guaranteed mid 180's for a race motor on my 09+, but it was $2000 plus parts. And the parts list wasn't one page.

I'm having issues keeping my planker from puking coolant in the paddock, I couldn't imagine trying to chill it down with 35 more rwhp

Eric Dorn told me the x-plane needs some pretty major head work to make big numbers and with that comes heat...he said a full race radiator is a must. Add a couple grand to the build for that alone.

The '09 Spies won the SBK championship on had about 220 or more and was said to be the hardest '09 SBK to ride according to a testing journalist. I believe he used the term "brutal" describing its power delivery,like a highly tuned two stroke either "off" or "on". I'm sure there are gains to be had from a different airbox,but other parts are needed to realize its full potential. I can see one giving a stock crossplane 7-10 or more hp like AKDMA got from an RC51,the lid especially looks like Yamaha had the EPA in mind when designing it.
Yea I read that article where they rode all of them, they said the R1 was nasty power wise and, the torque curve was realy high and hard to ride around.

What are you running in the radiator? Do you have to much coolant in the over flow to began with?

It matters when suzuki riders and Blake apologists are whining about not having enough power. I don't think it's the case and it'd be nice to shut them up.

If I'm not mistaken, Blake's GSXR is also an 09 model compared to Hayes' '12 R1

I was also watching Mid-Ohio on Speed. I guess they(Graves) uses some super expensive TC where Jordan Suzuki(Hayden) is using the Bazzaz TC. I wanna say that Yamaha is using Pagani, or something that begins with a "P" I think. Can anyone chime in???

("Everyone [in AMA superbike] is around the 200-horsepower window," said Jim Roach, Hayes' Graves Motorsports Yamaha crew chief) is made. The EFI throttle bodies and airbox are stock units as per the AMA rules. This was 2011 bike

problem is the "kit" box requires the "kit" frame this is where Swan BSB ran into issue (of course this is all an opinion and no way do i pretend to know what im talking about )once they had to swap the frames..the airbox had to go too...the bike was not good mid season on....

the Graves bikes i'd "guess" 184-186rwhp on the DJ dyno. Blakes GSXR1000 makes 189 on a GOOD day... the 09+ GSXR1000 is THE #1 biggest pos ever designed and hated by those of us that build them.

what hasnt been mentioned yet is that a huge part of the "speed" difference on the straights begins in the corners.

I have been in the same race with the likes of kevin curtain on an r1 in australian FX series and seen him blow by s1000rr's.. The FX rules dont allow any engine tuning other than full system and pc3 and his bike is regularly dyno checked after each race day (since he wins a LOT). each time the power figures are 155-158 RWBHP while the beemers he is racing put out the healthy 180-185

the key to his straight line speed is getting a much better exit out of corners due to the suspension set up/throttle control/skills and massive balls of steel! lol

outright bhp always helps but it does come down to a full package. my 07r1 has no problem keeping up with the new zx10s and gixxers that put out good 15bhp more provided i get on the gas well.

i only just had head work done to my r1 and have gained about 10bhp but the biggest improvement is in how much faster the bike revs (so even with similar power it develops it over a shorter period of time) but also a really good dyno tuno. with the new tune the biggest difference isnt the top end but, how early and hard i can twist the throttle out of the corners. the increased pick up off 0 throttle is staggering compared to stock.

also, peak numbers are very deceptive. you only use the peak power for an instant. what counts is the total area under the power curve and how early in the mid range you have good power. that will determine how well you get off the corner. no one is at peak power at the corner apex.

one last bit.. AMA rules are very similar to ASBK (australian superbikes) from what i can see so those bikes most likely see somewhere around the mid 180-190 bhp at the wheel but keep in mind that those engines are torn down and inspected after each race for a factory team and rebuilt after each season if not sooner. you could not sustain that power in a road bike and keep reliability. i have seen a race piston come out of a 07 r1 that produced 200+ bhp at the wheel, and after half a season of racing the piston pretty much just crumbled away from the gudgeon pin. they just dont last
