Chase has a good point though. You really have to measure these things on a track. Dyno numbers are going to vary widely across the board. I ran into this when I spent several years on the cbr forum. Guys dynoing stock bikes, power would range from 119 to 141 rear wheel horsepower. There never has been a consistency with dyno's and believe me, there are plenty that take advantage of this. You can literally take a dyno and make it read anything you want. There's several standards out there, so you will see variations across the board. Only way to evaluate or do a comparison is on the same dyno and prefferably same day with the same variables. Anyway a person doubting a cub just needs to ride one, not look at a dyno sheet. :cheers:

Back when I first had my old motor finished up I took it to a dyno, it pulled 59.6 hp...Thinking back that was prolly damn close to a realistic number for that motor at that time. Then I had the same motor reworked, and it put out around 80hp (based off what I previously had, and dyno sheets from a motor that was built identical to mine). I think between my old 80hp motor and my new cubs...I wouldn't be afraid to say" its for damn sure puttin out over 90..and maybe even between 95-100hp"

 

Bottom line being..I'll line up against ANY stock framed,cylindered 80hp banshee, and feel confident that I'm gonna win.

 

Like I said before..."cubs are no joke"

Dynos are going to vary bigtime. You wouldn't even believe where and how some the numbers that are floating around come to be ,or not to be, or wish to be, so lets just flush all of it. 421 Cheetah Cubs are a 193 BMEP@9700 RPM design... period(piped perfectly). Ive mapped several sets, averaged all of them ,and ran the maps through my programming and bone stock 421's will produce 95 hp(on gas) in a perfect world, with perfect jetting and perfect pipes....Jim

Ill put mine on a totaly un biased dyno if you are willing to pick up the bill just to see how it pans out, it will be the same one that I ran my passion motor on.

if you think cubs are so fake, head to your local drag strip and watch the little cubs beat up on the big ol t-rex bikes and etc.. they are no joke, and worth every dime spent! dynos are for tuning puposes any way, you can take a 100hp bike and put some no riding sob on it and take a 75-80 hp bike with a good rider and you can watch the 100hp bike get his azz handed to him!

 

just some food for thought.

is the low end and mid torque better than rz cylinders with the power valve ? :evil:

The RZ cylinders have power valves and the cubs don't. The power valves make a lot of torque and power down low and when they open up with the higer RPMs they run well on top too. The cubs run somewhat like a dune port on stock cylinders but make more power than you can with stock cylinders with a dune port, but they dont have power valves. They make for a fairly top-endy motor so, no the RZ cylinders would make more usable low rpm torque and HP.

i cant imagine even runin t rex cylinders..have you ever felt how heavy they are?? its rediculous..and the pistons weigh a ton as well..if u ever get a chance to feel the difference do it..piston prolly weighs 2 times as much as regular piston..

i bet breidys trex will give you a run for your money. regardless the weight.

exactly what i was trying to state rnbrad , people who sell the engines like to make everything look better for sale . IM not doubting cubs dont make redicolous power but these claims of 120 that i seen on these forums im quite skeptical even if i see the dyno. Variables theres alot...... Enough with the hp . bolt the cubs on and ride if your worried about hp just buy a hayabusa , turbo it and then ride it really hard ... im preety sure you wouldnt care about your HP output .

 

in no way shape or form am i saying the cubs suck. im just saying dyno sheets can vary due to the dyno operator , load factor . . . . etc .
