Jeff... What mods does the 12 have? SAE or STD horsepower? What correction factor? Is the assumption that's rear wheel HP correct? Thanx for the info. We just need details.
More ZX-12 Dyno Results

That ZX12R is stock, with a Hindle pipe on it. Fully stock and unbroken-in it pulled 159 and change. This is corrected SAE rwhp.
To correct and clarify Omega's remarks, Jeff did me (Akrapovic, BMC & box cut) at 159 SAE rwhp, then, on his suggestion, I changed fuel from junk to Shell. The next day I went to another dyno (not his) and got 165 rwhp. I have yet to return to Jeff's dyno, and won't until my cams and PCII are in.
Jeff Bloor is a well-respected person here in Toronto. He's Service Manager of a large Kaw/Duc/Suz/Yam dealership and does the high performance work himself. He's in demand for dyno tuning, and a lot of Busa drag racers from the States trailer their iron up to him. Super Bike teams use him, too.
His dyno is a new Dynojet 150 and he calibrates it off the Dynojet site regularly.
I feel his dyno reads conservatively if anything. But his results are roughly corroborated by the in-house dyno of Lang Hindle, who makes the Hindle pipes very close to my home. Hindle got a new, unbroken-in ZX12R - a different bike from the one Jeff Bloor ran - and put it on his dyno bed to test the pipe he's making. Hindle got 174 SAE rwhp.
These numbers are awesome, but reliable.
I'm glad I'm getting those cams and a PC2 in soon! Gotta get 180 horse ASAP!
Everybody get out there and gear your Busas down! The sky is falling!

Uh-oh, those are some impressive #'s. However, lets wait and see what some real world riders run in the 1/4, and what they do against Hayabusas in roll ons.

We are becoming wise elders, Omega. We are learning to not spank the children immediately but rather to trust that our quiet hints will steer them in a better, more constructive direction.
Quite a contrast from 6 months ago HAHAHA!
Everybody keeps your filthy mouths shut. Especially you Todd.

The ZX12R with a pipe on is going to be a killer quick bike. Nobody on a Busa will be able to touch it in a straight line unless they've been into their motor.
The 159 stock hp is about what we expected. What we didn't expect was that you'd be able to suck 15 more horses out by replacing the stock 4-2-1 pipe!
I assumed that the stock pipe would be very maximized already, but apparently all that cat converter honeycombing in there really clogs it.
15 horse from a pipe! The most a Busa is getting from a pipe alone (no box or filter) is like 8 or so.
Give the bike 15 extra ram air horsies at high speed and you're looking at 190 rwhp from a stock, re-piped bike!
If the 12's top end is limited by gearing and not electronically, a piped one is going to rip the snot out of the 1/4 mile. 9.5 and 150+ with just a decent rider.

Of course Busadan has a short temper! He's from Arkansas, like me. Don't hold it against him. Would you believe him if I said I had seen the slips (which I haven't... yet)?
For whatever reason, he thought that his word was good enough. Silly, he forgot what type of crowd this is! I have yet to meet Busadan in person, but we do have friends in common. They all have spoken VERY highly of his abilities. Still, I can understand your questioning his numbers, just like I can understand his frustration.
If Busadan wishes to share those slips with me at sometime, I'll be more than happy to post them for you. I will also understand if he doesn't, since he believes he has nothing to prove.
Now... back to bikes you "elders", you! Next thing you know, you two will be wearing habits, burning inscents and speaking in latin (pig latin)!

All true, and all not what anyone on here wants to acknowledge.

Again: So now R Gadson is just a "decent" rider ? As far as anyone "acknowledging" anything, I would prefer to confirm, instead. Ordered Muzzy 2 weeks ago. Looking for bike on west side of country.

How much does "average joe" Busadan weigh ? I weigh 220. With 1.5 ~ 1.6 60' times, mid 9's would suggest light weight, in relation to horse power. 330' time would be of interest. Beyond that, it's pretty routine. Also, there is going to be a wide variety of et. due to differences in track altitude, traction, and "air"...... ..Also, don't always assume that colder air is going to be "faster" than warm air. Humidity is also a factor. Our local track runs best midday, and gets "slower" as afternoon progresses, and humidity goes up.

To Dp: Ran with bar, but not slick. Had 207 Dunlop 180x17 road race "take off" . The 10.07 run was with 1.6sec 60', with some tire spin. Shift into 2nd pulled much harder, and slammed me into tailpiece. Top end speed was only 135 mph, with a 10 mph headwind. Have gone 139 mph, with no headwind, pure stock. Bike should get a 1.4 60' time with slick. Would have obvious effect on overall et. ............................. ..Last I heard, Gadson weighs about 160. I haven't seen that weight on my scale, in awhile.

Chris, by "decent" I meant a serious amateur dragger.
Whatever Ricky was riding (pre-production), the production unit may be even stronger.
I based my et/speed guesses on 175 static rwhp, which is 20+ hp more than a good stock Busa. A good stock Busa goes 10.0 in the hands of a "decent" rider. Probably Gadson could take a 155 hp. stock Busa to 9.8 with practise.
My thought was that 20 more rwhp and 20 fewer lbs. AND lower gearing should be good for at least .5 second.
Do you think I'm being a little optomistic? Does it take more hp than that to get half a second?
I don't remember ever seeing any times posted for a dynoed 175 rwhp Hayabusa, but I would have expected 9.5s.
By my (flawed?) reasoning, Gadson with one of the 12s dynoed here in Toronto should be able to go 9.3s.
SORRY to be posting on both sites, but the conversation is going on at labusas, too.

Sounds like you need a rear cowl pad from SargentCycle?! Hey DP - they say wisdom comes with age so you ought to have accumulated some by now!

I dont doubt the 9.70's is capable on a bone stock busa. I ran a 10.14 with a 1.80 60' on a totally bone stock busa with 900miles on it. 1.5 60's are within reach as I have seen my 205lb. buddy cut them all day on his when it was stock. 3 tenths of a second quicker 60' would put me at least at 9.80's and I weigh 195lbs. I have a scanned copy of the time slip if anyone is interested.

Thank's Peter for the solid defence. One minor correction though, and it does not matter much is the dyno is a model 200.
Just so every one knows, that because it is now insane season here at the dealership and I must also cater to all of our new all brands and all catagory of bikes(Honda too),otherwise the sales dept. will be a tad unruly, it will be very hard for me to keep up with the Jones's as far as the ultimate tuning for the fuelly bikes for now.
However, this fall I will be attending a indepth coarse at Dynojet and will be upgrading our Dyno to a 250 with proper load control.
For now I will still be able to get rid of the nasty off idle problems on the 13 and trick the 12 a little bit, but until the load control arrives I will be very limited to minor upgrades only for the duration of this season.
No load control - no actual truth.

Just goes to show you how much of a difference weight makes! For us 200+ pounders power adders are always an option....

Busadan: Good work on the 9.75 as you inferred, there are days when the gods of gofast smile. I've been doing this since 1970, and went through various bikes of then, and now. Early to mid 70's: H-1's, and Kaw 900"s. 1980~90: Suz Gs1100 and 1150's. 90's ; ZX-7 and ZX-9 Kaw. Now: Busa. ................................... ..My best track was Fremont, Ca. Even though my local track is about the same level as Fremont, bike wanted to run 2 jet sizes richer. The "gods" smiled that day. Kaw 500 drag bike set IDBA Fuel record (500 2 stroke) 10.45 @ 133 mph, in 1975. Of course, I weighed 170, back then. 220, now.
220, now.OB_Busadan

c.dolan, POST YER TIME SLIPS, DOLAN.
LOL! Just kidding. You were FLYING running that quick in 1975. Good job, back at ya dude. I saw your pics on labusas. You do go back. The oldest pic I have is of me racing a KZ900. I never ran better than a 10.24 on that bike. I may see if I can get it scanned and post it on labusas. I have some old pics of club roadracing action from my roadracing days with CRRC down in Texas. I'll give posting some of them a shot also. I may need some guidance on the posting procedure.
