Horsepower Numbers ?
g`day fellas, this is my first post on here,,
am interested to know what sort of Horsepower/Torque numbers have been seen from the 1286 kits(standard bore, stroked crank) with headwork, cams, pipe, pc, etc,, i realize this is a pretty open question so fire away,,,

Are you referring to stock stroke with 3 mm bore 1287/1290 kits?
If so #'s are dependent upon many factors such as piston weight and compression, cams, timing, temperature, humidity, fuel, tire pressure, wheelbase, dyno operator etc etc. Hence I would expect #'s range from mid 180's to just over 200.
That being said, the only important # is the mph at the strip.

yeah, regardless of the different combinations to achive a sub 1300cc motor, what are the best "real" dyno numbers seen on a sub 1300 motor ,, as i said in the first post, this is a very open question

I have a 2000 ZX12R with a 1290 kit and 3MM bore. High compression Sweko piston and a 35 shot of dry NOS. This bike is putting out 196.8hp to the rear wheel on engine and 240 on NOS.

Biggbaby - are you running stock cams? have you had any work done to the head? Thanks.

Depending on the dyno and conditions, I've seen 192-202 H.P. / 111 Ft. Lbs. with my 14:1 CR Muzzy 1270 kit.

[quote 1290 kit and 3MM bore. .
60mm stroke (1290 kit?) and 86mm bore (3mm over stock bore), total of 1384cc?

I'd expect 190-195 depending on compression and pipe.

ok, it seems that you can get anywhere from 190 to 200hp with a little work,,
what horsepower numbers have been shown (are known) from a "fully" worked (race) naturally aspirated (no gas) 1286 (1290), ??

I've seen 183 RWHP out of a 1270, stock cams, pump gas, improperly setup. That is SAE HP out of an honest realistic dyno. Suffice to say if I extra if it was setup properly and some good fuel I would say approaching 200 RWHP should be doable with some good headwork. Talk to Sal if you are thinking about getting the most out of your 1287cc motor.

one of the reasons i raised this subject is to try and establish why it is that sub 1300cc Hayabusas are capable of achieving a real 200-210hp,, why not the ZX 12`s also,???,
it seems to me that everyone is sticking their hands in both pockets and saying that 190, maybe 195 is it for a 12, huh!!

"sub 1300cc" busas? As is the stock motor 99-07? NONE of them are doing that stock. We get them in here all the time. Maybe 160s RWHP or low 170s. 12s usually put out more. Even the 1340s 08+ are in the upper 170s to low-mid 180s if tuned right. But that is a far cry from 200 RWHP if we're nit picking.
I've seen a 1397 Busa on pump gas making good power once got all the bugs ironed out of it....and it did break 200 RWHP once done right.
You were primarily talking about piston kits. There have been many that routinely break 200 RWHP without much trouble....generally the ones that are stroked. Whole different ball game, as well as a lot more $$$

yes i did say sub 1300, but, for purposes of the discussion, many 1340 busas are producing 200 -210 at the wheel, (not to mention Fred Vances 230hp), ,+50cc would not see "that much" improvement,, keep in mind that i am not talking street bikes here, race deals,,,

My 1340 was 205. Could be again if I'd put it back together,...... Hmmm
Available in kit form if anyone is interested.......

So we're clear and not misleading other readers....surely you are not saying any
STOCK
Busa motors, whether 99-07 or the 1340cc 08+ motors
are making 200+ RWHP on pump gas, SAE.....
RIGHT?
Just so we're clear.
If you want to say its a 1340cc Busa....but its got crazy compression, huge cams, porting for a peaky screamer....thats an entirely different story. There is a very fast n/a busa on the salt flats that is just under 1350cc.....n/a Busa. That is far from a stock engine.
As Doug stated, over 200 RWHP can be achieved on an n/a 12R. Remember it was you who was talking about a big bore.....then you stated how come no 12 makes more than 190-195. If you take off your big bore only requirement and stroke the motor too 200 RWHP can be had with relative ease.
Just remember to compare apples to apples. Out of the box, with basic bolt-ons the 12 ROUTINELY makes MORE RWHP than the older Busa because the 12R was in a higher state of tune.

hay Ship, chillout, i have no fight with you, go back read my first post,,
all im trying to establish is what horsepower a naturally aspirated sub 1300cc ZX12 is "capable" of, whatever bore/stroke combinations, regardless of what fruit one has in there,,(no gas)
the 1340 Busas are the only benchmark that we have to guide/compare with,,,
if Fred Vance`s Bonneville Busa can make 230, surley a 12 is capable of 220-230 also, ?,, why has no one achieved it, or have thay,???,,

Under 1300cc can make 200 RWHP. Built to an extreme level without a cocern for street one could go higher (obviously). With a phenomenal ram air from the factory if it was setup in a slick aero chassis we're talking 220 mph potential....if not more.
Aeros would be the other side of the coin to address. The 12R is naturally less aero than the Busa....

the 12 has a narrow frontal area than the Busa,, the Busas aero advantage comes from the "enclosing" ducktail section,,,,

Regardless, in the macro scheme of things there is a reason why the 12R has more power with bolt-ons than the older Busas....yet somehow didn't necessarily trap higher speeds in the over 1 mile type flat out runs.
Overall the Busa is the better aero package, which is why with equal HP....even though the 12 has better ram air and pulls better in the upper gears as the ram air system pressurizes...by the time its totally flatout....aero makes more of a difference and it starts playing into the hands of the Busa.

we shall see. i am stroking my 12 this season as soon as i get done with the duster and playing with snowmobiles. it better do 200 on a happy dyno.
as for what shippy said. i usually always win dyno shootouts with my stock 2000 zx12 with a muzzy ti system on it. the other year two new gen busas showed up with bolt ons. i beat them by 1 hp on my little 1200 tehehehehe. wait till it is as big as a gen 1 busa.
the best older busa engine i saw pull a 172hp i beat him by 10 hp. it was a b king.
hell a stocker will not get past 160hp. but the torque at the track is way different than my 12s

----I own the video Mach 2 and 3 and have probably seen it at least 5 times as much as you as I have it just about memorized. That doesn't change what I'm saying.

----While they are all pretty quick the blackbird would have STONE STOCK gsxr 750s breathing down its neck. Times have changed.
