your point is?

 

Did you read the other posts? My point is he said he will send raptor13 home with nothing but his banshee, I said theres nothing wrong with. He would still have the better quad left....

 

Stay in school kid. It's not a guess. There are general calculations for converting 1/8th to 1/4 mile times. Nobody is claiming it is spot on for every combination. But you can use weight/horsepower/ET calculators to get a base. There is definitely a calculation on weight to horsepower that is needed to run a certain time.

Here is a whole list of calculators for you to dispute > http://www.wallaceracing.com/Calculators.htm

lol

 

well mike what would the stock pred run the1/4 mi if it runs a 8.7 1/8th

 

Predator>Rappy 700

Raced one three times, he was stock and mine was stock. Beat him by 2-3 bikes every time and started to pull away slowly on top end. Should the Rappy beat the Preddy, yes. No replacement for displacement! In this case a 499cc beats a 686cc, if I am correct on the cc's. LOL. Peace!

 

from what i hear and read- they will be close stock for stock- all because of the raptors low compression- bump it up to 11:1 or 12:1 and its a whole different beast probably

 

Boys and girls displacemeant doesnt mean a thing anymore.If that was the case those 450's wouldnt be that fast.It horsepower per cc.A 450 for example has more horsepower per cc than a raptor or a ds.Thats why there as quick or quicker.My ds or the raptor might be 653cc and 686cc but the 450cc are still as quick.Displacemeant means nothing anymore.

 

I agree completley about the displacement. It never has meant much. Look at banshees, my shee is a 421 and makes my 700r look like its in reverse. Four strokes are different, but still, engine size means nothing. It comes down to who is the better rider 90% of the time.

 

Or who ever has the most money.On a drag if oyu have a guy thats a perfect rider on a stock banshee and a guy thats average on a 421cc banshee then the guy with the 421cc banshee will get it.Unless he is real bad at shifting.But i agree to that rider matters alot.

 

Please stop while your ahead because you sound like a total noob.

Displacement does mean something and it always will. It means something in every application, cars, trucks, motorcycles and everything in between. If you think it doesn't, that just tells me you are clueless, and don't know anything about engines.


Here is a little lesson in displacement for you regarding these quads in question.

1) First, the larger displacement will increase torque. Torque is what gets you moving. Larger bores will increases torque in the lower rpm range. It also will make more power and torque with less effort.

2) When it comes to the raptor 700 it has a low compression motor from the factory (9.2:1). It makes the same horsepower as high strung 450s but it starts making the power lower in the rpm range and it also has more torque than the 450 motors. Why? because of DISPLACEMENT.

3) If you understand the above you'd know the reason the 450s are close in speed. It is because of a high compression motor and weight. They are higher revving motors with higher compression pistons that don't make power until they are wound up... similar to a 2-stroke engine. Try taking a 450 and put it in third and crawl a steep hill and you'll see why displacement means something. Another real world example where displacement makes a difference is it's ability to move weight because of the increased torque.

Now with all that being said. If you take a Raptor 700, install a higher compression piston, lets say the same as a standard 450 engine (in the 11:1 to 12:5 range) you will see A LOT more horsepower and torque being made than a 450 with everything else being the same.

If you want more details of why displacement still means something, just let me know, I'll school you a little more. You need to learn to spell the word displacement as well.
