dunner250 Posted January 31, 2010 Report Posted January 31, 2010 On another website that I was reading a 4 stroke making the same hp as a 2 stroke will beat a 2 stroke, and that the 2 stroke will need to make more hp because of the way the 4 stroke makes its power. I believe it has to do with the torque is made so much earlier. Just wanting to know if that is true? And all other things being equal. Quote

dunner250 Posted February 1, 2010 Author Report Posted February 1, 2010 So is there a correction factor? Ported 450 say low 50hp vs a ported banshee 60hp, who wins? Quote
RagunCajun Posted February 1, 2010 Report Posted February 1, 2010 (edited) A good old saying is "Horsepower sells cars, torque wins races" How much TQ does the two bikes make, im curious about that one. Edited February 1, 2010 by RagunCajun Quote
dunner250 Posted February 1, 2010 Author Report Posted February 1, 2010 4 stroke 33tq and 2 stroke 35tq Quote
J-Madd Posted February 2, 2010 Report Posted February 2, 2010 its true a 70hp 450 will beat a 70hp banshee all day long 70 hp Banshee = rideable and reliable 70 hp YFZ = ticking time bomb (Hell, Both '04 and '05 stock YFZ=ticking time bomb in my experience!) Also, 70 hp YFZ = $$$$$$$$$$ Quote
bada450r Posted February 3, 2010 Report Posted February 3, 2010 70 hp Banshee = rideable and reliable 70 hp YFZ = ticking time bomb (Hell, Both '04 and '05 stock YFZ=ticking time bomb in my experience!) Also, 70 hp YFZ = $$$$$$$$$$ exactly, and i would think that if its a long enough race the banshee would win. Quote
quaddad817 Posted February 4, 2010 Report Posted February 4, 2010 ive been looking at alott of dyno #'s latley. and it seams like cyngle cylinder 4 pokes dont get get far over 70hp. on motor! so lets get our lil 2 strokes over 90hp. on motor, n kick there asses! i think we have weight on our side two..

dunner250 Posted February 5, 2010 Author Report Posted February 5, 2010 I know that a 2 stroke will show bigger numbers on a dyno. If you were to line them up and race how much more hp would the 2 stroke have to make to be equal with a 4 stroke. I know that it takes alot more $ for a 4 stroke to make good #'s, and thats fine because I will let the other guy spend the money on the 4 stroke. Quote
kolb02 Posted February 5, 2010 Report Posted February 5, 2010 4 strokes have weight on there side! I ride with 3 60+hp 450's and they all weigh less than 235lbs. But I still beat them in the sand drags! Quote
fastbanshee8 Posted February 5, 2010 Report Posted February 5, 2010 Basically, it all comes down to traction. You can have all the HP in the world, and it won't do you any good, if it's not hooked up to the racing surface. There are a lot more factors to winning a drag race, than just torque, and HP. Quote

Titan up Posted February 6, 2010 Report Posted February 6, 2010 My friends stock bore/stock stroke KENZ built Raptor 700 put down 74hp and 54ft lbs at the wheels after he got he got it built and tuned...My Banshee has a fully drag ported 421 cub with all the bells and whistles on it. On paper my bike should make atleast 15 more HP than the 700, but in the real world he gives me everything I can handle and more. This is dragging on sand..uphill and flats We trade wins all day long with each other. He's 230lbs I'm 200lbs...We both admit my shee pulls slightly ahead on the very, very, top end...Maybe a bike length up the hill. I would put my money on the 4 stroke if they both made the same "peak" HP on a dyno. Quote
amstall Posted February 6, 2010 Report Posted February 6, 2010 (edited) 4 stroke 33tq and 2 stroke 35tq Not possible! a 50hp 4 stroke will have way more torque than a 60hp 2 stroke. That's pretty close to what my Banshee and YFZ run for hp. As far as which is faster it all depends on how far you're going. The banshee will take the YFZ off the line, but once you get into 4th the YFZ will overtake it.....but if you keep going the banshee will make up the ground again.
