Improved FD

well, he did have his g/f on the back, I'm sure that didn't help, ha

what speed? that's a critical piece of the equation you left out

And cars have about 16 times the rolling resistance of a bike. That's being generous, if you compare the contact patch of a bike tire vs. a car tire.

Hocky

Sounds like that was one hell of a good race. lol

Improved FD

which is why bikes own the 1/4 mile, but they don't fare as well in high speed rolls, esp > triple digits

motorcycle aerodynamics have admittedly come a long way....word is the new ZX-14 will be good for an honest 200 (or very close) with the speed governor removed

The 02R1 is a turd compaired to today's litre bikes, the GSXR750 ran a better 1/4 time and had a higher top speed when it came out in 2001. I guess I should have said modern litre bikes.


This race was set-up and there was no BS about it. He ran several differnt bikes to see how it would do against them.

And yes the good rider part comes in with how well they do. Did they select the proper gear to be in(you'd be surprised how stupid some people can be), did they go to WOT right away or were they scared to lift the front end, and most of all did they stand straight up in the wind or lay on the tank.

There are many Supra vs Bike vids out there and to run even with a litre bike+ from most of the vids I've seen it takes hi 700RWHP and up.

So how much power do you think it would take an FD to pull dead even with a Busa or other litre bike?

Improved FD

I'd say to run a current liter bike an FD prob needs 400 rwhp, and about 550 or so to run a stock Busa...aerodynamics on the Busa are decent

Improved FD

although the above post was pretty much a conservative guess, it may be overly conservative!

Improved FD

ergo, the aerodynamics of the FD are really good, the aerodynamics on the Viper are really bad, or....

the claim of 886 rwhp is a steaming crock of ****

matty

yep.

Busa413

Correct but the current litre bikes are VERY close to the Busa so I wouldn't think it would take another 150RWHP to run with a Busa compaired to a litre bike but who knows. I still think it will take more than that but I can't say I've done it I would just have to see it to believe it.

Improved FD where in NC are you located? How much power are you putting out with your car?

rotorsownyou7

50 roll...

rotorsownyou7

A FD should be dead even with liter bikes at 450 whp, and a little over 500 for busas from a roll. You saw how Hockyz did vs. a modified Busa, with what I would guess is 550-600 whp.

IndyKid

When I was bpu I raced a 02+gsxr 600 and walking it over 60mph, I also ran an 03 gsxr 1K and got beat by like 15+cars. Since I have been single(520rwhp) I've raced an 05 gsxr 750 with a passanger and won by 2 cars. I have raced a few fd's with over 400rwhp and won and can tell you that you if you think that a 400 to 450 rwhp fd can beat or get close to beating a newer 02+ 1k bike you are just plan stupid.

hmm interesting ive seen 400 -450 hp fds beat 500hp supras it roughly takes a supra 90 to 100 hp to beat an fd with 400 so should be pretty close to you indy but anything can happen on the street, good races though thats a fast fc

IndyKid

Both races where from a 50/60 roll. 1 to 2 cars both times and I would get crushed by a 1k bike. If the mk4 that you saw are running big turbos on pump gas then I not really surprized.

greg schroeder

The FD kicked some @ss. Nice work.

ah prolly you have a nice supra man i like it alot! I plan to get on after im done with the fd

rotorsownyou7

450+ wheel hp FD's have the ability to run mid 10 second 1/4's. Today's liter bikes run low 10's and even high 9's. So from a roll, yes, a 450 whp FD will hang dead even with a liter bike, depending on which it is. Just like the above, Steve's car was pulling a GSXR-1000 hard with only 480 whp, and hanging with a Busa.

IndyKid

Okay, if you are running slick on the fd you will see high 10's those newer 1k bikes see low 10's and on the street with slicks YOU WILL GET OWNED. Plus you have no proof, show me proof. Here is one of my best friends mk4 racing a 1k bike and you can see that it's a close race. This car has 775rwhp and traps 141mph.

Cars own bikes on the street from rolls. 1/4 times if a car is pretty close to the bike, the car should win. So a high 10's RX-7, 450 whp, vs. a low 10's GSXR-1K, the RX-7 should be very close depending on what mph they start from.

I don't have proof? Whoo-hooo... You do though, because you show me a video of a guys car on Supraforums that I have already saw, racing a bike. Did you see Hockyz video? He is one of your friends correct? It took him what I would guess is 575 whp to stay with a modified Busa. He said he was beating that YZR6 on motor only. So he's out running mid 11 second bikes on motor. I say he makes 425 on motor.

And we are talking about RX-7's not Supra's. It doesn't take a RX-7 775 whp to trap 141. Maybe 550...

Umm hocky's car is LS1 powered, just FYI so that doesnt even consider itself an rx7 anymore.

And you cant compare supras and rx7s. Supras are known to make massive hp. And although it takes a higher amount of HP to run a good time, thats due to the fact that its heavier than an FD and traction. Thats all. Of course an FD wont need massive hp to run a 10, it weighs like 2 ounces.

Improved FD

lots of people claim to have 400+ rwhp, but that doesn't mean they have it....perhaps that makes YOU stupid to believe them....you strike me as an angry little punk rich kid anyhow, with an axe to grind, maybe your porker Supra got it's *** kicked by a few bikes?

I guess you are calling Steve Kan a liar?

rotorsownyou7

Well I am used to LS1 powered RX-7's ... and I know all of what you said. So....

Hocky

The cars that he's speaking of a certainly 400+whp. ;-)

Busa413

Improved do you know of any RX7's in eastern NC with the power to run a Busa or litre bike? If so I can line it up so we can see what happens.
