96shee84z28 Posted January 21, 2004 Report Share Posted January 21, 2004 hey guys i've always wondered how much hp my shee can make and what my top speed should be is there some kinda equation or can you guys give me a rough idea..... thanks. my mods are t-5's, toomey 2 into 1 filter, no tors, pro design coolhead 20cc domes, vforce reeds, bored 40 over, stock sprockets.

spoin39 Posted January 22, 2004 Report Share Posted January 22, 2004 I would guess you are close to 40-45hp. as for topend, maybe 75mph. Quote Link to comment Share on other sites More sharing options...
Dextreme Posted January 22, 2004 Report Share Posted January 22, 2004 mmm...hp wise, I would say more like 50ish since you have Toomeys (39-40 is stock). Quote Link to comment Share on other sites More sharing options...
Aussie Quad Racer Posted January 22, 2004 Report Share Posted January 22, 2004 less than 45 to get my bike to 50hp it took unifilter clamp ons stock carbs ported cages with carbon tech reeds ported intakes, match transfers to case and sharpend up transfer bridge 0.040 over wisecos shaved head(150psi) pro curcuits Thats 50 rear wheel horsepower in 5th gear. 5th gear is basically 1:1 so it gives you best reading. Its easy to make a hp chart look higher by running it up a gear lower. Quote Link to comment Share on other sites More sharing options...
dirtbike killer Posted January 22, 2004 Report Share Posted January 22, 2004 I say about 50. I did 52 on the dyno with about the same mods.(at 4500 ft) Do a search, you can find my dyno sheet. I posted a couple of them. Quote Link to comment Share on other sites More sharing options...
Aussie Quad Racer Posted January 22, 2004 Report Share Posted January 22, 2004 remember all dynos read drifferent and in the end the peak hp means nothing. Runing a vehicle on a dyno to see how much power is really pointless, runing it on the dyno to tune it is a great idea. Quote Link to comment Share on other sites More sharing options...
spoin39 Posted January 23, 2004 Report Share Posted January 23, 2004 So a 2into1 isn't that great like some say or just his mods didn't respond to it? Quote Link to comment Share on other sites More sharing options...
dirtbike killer Posted January 23, 2004 Report Share Posted January 23, 2004 I like the the 2 into 1. It gave me alot more bottom end. Check out the power at 6000 rpm. The single is putting out 10 more hp, and also has a better power average though the power band. The shee is a lot more fun to ride, feels like an different bike. A dyno is how you find out how much power your getting. I dont see any other way to get this. I dont think its pointless. The question was, how much power do we think he is putting out. I did a dyno, I had about the same mods. Thats what I was getting. You posted your hp. How did get your numbers, since dynos are pointless you must of got these numbers some other way.

Stuff Posted January 23, 2004 Report Share Posted January 23, 2004 I have to disagree with dynos being "pointless" for measuring peak horsepower. How would you know which way to tune if you didn't measure power? They are a great tool to study, tune, and design engines and drivetrains. There are equations that can estimate power, torque and all sorts of stuff, but when it comes to the real output, a dyno (if properly set up) will give very accurate numbers. If measuring power on a dyno were pointless I guess NASCAR, GM, Ford, Dodoge, local speed shops (just to name a few) would be wasting their time if that were true. Just my thought.

Aussie Quad Racer Posted January 23, 2004 Report Share Posted January 23, 2004 If you re-read my post it states "Runing a vehicle on a dyno to see how much power is really pointless, runing it on the dyno to tune it is a great idea. " By this i mean running your bike on the dyno without any intension to tune or mod and just get a figure is a waste of time and money. To tune the bike on the dyno and/or mod it a great idea(as stated in my original post). I ran mine on the dyno to tune it not to get a figure.

dirtbike killer Posted January 23, 2004 Report Share Posted January 23, 2004 remember all dynos read drifferent and in the end the peak hp means nothing. Runing a vehicle on a dyno to see how much power is really pointless, runing it on the dyno to tune it is a great idea. Who doesn't dyno there " vehicle" without tuning in mind ? The main reason to dyno is to see how much power your putting out. That way you know what direction to go, if your where you want to be, or if your even going in the right direction . When you took your dyno I bet the first thing you wanted to know was how much? Forget the reason you wanted to know, thats what you were after: HP NUMBERS. Thats what dynos are for. Like Stuff said: I have to disagree with dynos being "pointless" for measuring peak horsepower. How would you know which way to tune if you didn't measure power?

J..J. Posted January 24, 2004 Report Share Posted January 24, 2004 I think you're all missing what Aussie's trying to say here, sure we're all keen to see the final number, but all dyno's are different, different SAE Corrections are applied and different gear ratios are used, Peak HP readings can be manipulated very easily. The dyno should only be used as a reference tool to see if you're tuning towards your goal. For your info, HP can not EVER be measured, only calculated, as it is a product of torque and RPM Quote Link to comment Share on other sites More sharing options...
dirtbike killer Posted January 24, 2004 Report Share Posted January 24, 2004 The dyno I use measures rear wheel hp . There is no corrections for gears. The dyno knows how much power it takes to turn that drum, period! It doesn't matter whats on it, its measuring power to the drum. There are different dynos, but if its working right you will get the same basic number. Torque is measured and hp is calculated, there is no different ways to calculate hp. X amount of torque at X amount of rpm = x amount of hp. I have had my drag car on many different dynos, and get the same results. If a dyno differs from the masses of other dynos, something is wrong with it. I dont know how many dynos you have been on, but I have been on too many to count. Saying all dynos differ, is like saying all calculators differ. 2+2=4 on one and 3 on an other. Because thats what dynos are. Quote Link to comment Share on other sites More sharing options...
Banchetta Posted January 25, 2004 Report Share Posted January 25, 2004 Your gone......I've been on 3 different dynoes and got 3 totally different numbers on my streetbike... I agree w/ everyone else...You CAN munipulate the dyno numbers by SAE correction, elevation, temp, humidity, etc. not including that if you strap a shee down and run it, how much hp are you losing from squatting 9" of suspension down and putting all that force on the tires to make them not spin....I've ran the same dyno 2 months apart and got a 6hp difference w/ no changes.....dynoes are for tuning only and final hp # doesn't matter, its for a reference to get a base and to tune from there....the final number can change from day to day, so final numbers don't mean anything......2+2=4 in the real world, not dyno world...

dirtbike killer Posted January 25, 2004 Report Share Posted January 25, 2004 I dyno on good dynos with my car. I dont know whats up with the sh t you dyno on. I have dyno my shee a number of times, and unless I change something, its the same. When I say the same I mean corrected for the conditions. I have had my car on the dyno too many time to count, more than three times. We are in the works of getting a dyno in my partners and my shop. It will be a car dyno. I know I dont know about about shees as good as you, but I know a lot about dynos. I have been drag racing for 10 years, and have a few friends that own them. I will too soon. If setup correct you will get a true hp number. I'm done with this subject, so we can just agree to disagree. Quote Link to comment Share on other sites More sharing options...
