951 vs GSX-R?
Hi!
Something weird happened to me tonight, I wanted to let you know about that. I was slowly driving on a traffic-free freeway at about 50 mph and what looked like a GSX-R 1000 started to tailgate me with a yellow similar bike (I don't know what brand). Just for fun, I immediately floored it to see how bad he would outaccelerate me. The yellow bike didn't want to play, but I saw the GSX-R starting to chase me doing a wheelie. He turned on the left lane, still doing a wheelie, trying to smoke me. I stayed there until about 80 mph, I would even say that I gained about a carlenght on him. He saw that the 4 cylinders Porsche was faster then he tought, so he stopped doing his show off wheelie and he he started to slowwwwly reel me. He passed me at about 120 mph and at 140 mph he was about 1 carlenght in front of me (meaning that he had gained about 2 or 3 carlenghts on a 80 to 140 mph acceleration).
That was a really big rush to hear the bike running at about 10 000 RPM and only gaining on me inches by inches. Aren't they supposed to outaccelerate much more powerful cars than a chiped 951 running at 15 PSI? We then took the same exit and the guy didn't even look at me. He talked with his friend at the redlight, both quietly looking at the sleeper poor man's Porsche beside them.

Those GSX-R1000's are fast. Plenty fast. I think he may have been toying with you, honestly. At least doing it on one wheel seems like toying to me. I had a Hayabusa(GSX-1300R) and I could mop up anything on the road and not even downshift to do it from 6th gear.

My company writes warehouse inventory software for motorcycle parts distributors who buy straight from H-D, Kawasaki, Ducati, Honda, Yamaha, etc. Most are in California. So I see bikes all the time when I make a personal visit to check on things. These blokes are so into bikes they would eat them if they could digest the metal. I dont ride, I just gawk. Having said that Ive seen some of them ride and nothing ever coming out of Ferry or Enzos skunkworks would even give these things an honest race. Its pointless really. They can do 0-100 in the time it takes anything on four wheels to do 0-60. Thats why when you watch Americas Best Police Chases on TV and theyre chasing a bike (re: not an entry level Vespa) they only catch him from behind when he crashes into an embankment.

Heh... Concerning the Camaro SS LS1, their average trap speed is 105 or 106 mph which is about the same as a 951 with minor mods (chip, exhaust, boost controller...). The moded 951 pulling just a bit more at high speed, it's totally believable that I pulled beetween 1 and 2 carlenghts on one on a 20-140 mph acceleration. I even asked what year was his SS and he confirmed that it was a LS1. I posted the results of the race, I don't know anything about the driver and if he is good or not. Some Camaro SS run high high 12s bone stock, some others run mid 14s. It all depends.
Also, I totally know that most bikes are invincible unless you own a 600+ rwhp single turbo Supra running a 200 shot of NOS. Most bikes run in the 10 seconds range at over 130 mph, meaning that they should pull 20+ carlenghts on me in no time. I just wanted to let you know about the great time that I had playing with the guy. He was really thinking about being able to outaccelerate me even doing a wheelie and it didn't work: our 951 are great highway racers. If he'd have been more serious, he'd have pulled buslenghts on me.

Mich924s and UDPride, I think if those of us that ride sportbikes keep it up, we're going to move a bunch of listers to add two wheel rockets to their sigs and garages <img src="graemlins/burnout.gif" border="0" alt="[burnout]" />
Yan, it's a rush to be out on the road and find a four-wheeler that wants to throw down a challenge. For an old guy, pushing 45, that rides sportsbikes hard and drives my 951 fast as well, it makes me feel great to dice it up on an open stretch. Both parties get a kick out of it. It sure isn't the mature thing to do, but if maturity were the motivation behind why we chose our cars, we'd all be in Volvos!
Cheers,

I'm in league with Mich on this one. The guy was completely toying with you, had he put his mind to accelleration and not popped the wheelie to show off - he would have passed you almost instaneously. Chances are he was checking to see if he could pass you in 6th gear. :-)
I used to own a new 1996 Kawasaki ZX-6 a few years ago, and off the line most V8 cars would take me for 1-2 car lengths because I would start out "easy" in 1st gear to avoid tire burnout or popping a wheelie. Once I got in got and wound it out, I'd catch up before the car shifted into 2nd gear, and be several hundred feet in front of the car by 1/4 mile.
Sheesh, even my big fat Honda VTX 1800cc cruiser will run 10.5 quarter miles. Of course 100 HP and 105 lb ft in a 750 pound vehicle has a pretty good power-to-weight ratio. Thats about the same as 490 HP in a 944 Turbo. :-)

I've raced a lot of bikes in my 951. I'll ALWAYS get raped off the line. 10-20 car lengths by the time I hit 80mph. From a 80mph roll, it's a lot closer. I'm even with the lower end bikes (on pump gas, low boost), but I'll lose to the big boys. Haven't raced a bike at high boost/race gas yet...

I agree with rage2, there's no contest on a standing start: a properly driven bike should put more than 20 carlenghts on practically any production car on the market. I tried more than once...
At higher speed, it's very possible to outaccelerate a bike with a seriously modified car. There are some street legal Supra's with over 600 rwhp that can put multiple carlenghts on Hayabusa's and comparable bikes, especially above 140 mph. I have a video of Bryce's Supra pulling about 5 or 6 carlenghts on a modified ans well driven GSX-R 1000 bike.
I know that the bike was toying with me, but as I said before I'm pretty sure that his goal was to outaccelerate me even doing a wheelie. He must have tried it with sucess against some other sports cars, but he seriously underated the "poor man's Porsche" in front of him. If it wasn't his goal, why would he do a wheelie at over 60 mph to impress me and still stay behind me? When you want to impress someone, you at least try to show your stuff in front of him!

I documented it nicely on the 944 Turbo forum in <a href="http://forums.rennlist.com/cgi-bin/rennforums/ultimatebb.cgi?ubb=get_topic&f=18&t=000626&p=" target="_blank">My 951 mod story pt 4 - Dyno Day!</a> thread. Videos, pics, dyno charts, they're all there. I've learned a few other things about that day :
- The reason why the non loaded dyno made such a big difference on boost levels compared to on the road was due to a leak in the rubber boot between the intercooler and the pipe to the intake manifold.
- The runs in the thread were done 2 days after the motor / base fuel maps / ignition maps were done. I've made TONS of changes to all the curves, resulting in much better power across the board.
- The reason why the boost curve was so rocky was because the boost control was done by the FB speed setting on the AVC-R. Since I left it at default (3) it was too slow, causing boost to rock back and forth. It takes a while before the AVC-R learns the duty cycle curve. It's learned it now after a month on dry roads, and I can turn that feature off completely so boost is regulated by the fixed duty cycle map that it's learned.
- I installed a Blitz Power Meter, so I can do "dyno runs" on the highway. I've seen a best of 380hp at the wheels so far.
- Wideband O2 sensor is in my hands, just gotta get it installed... more accurate fuel curve very soon.
I'll be doing another real dyno run once I get the sucker tuned.
