Oh, but Lag, then it would have sold better, they would have continued production, and it would be 40k for an 89S4 instead of 17k.
How is your fuel curve Lag?

Laughlin,
Does anyone have 1/4 mile and 0-60 on the boosted 928's?
Just from doing the 1/4 mile calculator, it estimates 11.5 in the 1/4 mile, do you think thats high or low? A stock Yamaha R1 runs 10.4, I am pretty sure. I am pretty sure the R1 would take a boosted 928 off the line but as you have proven, a rolling start could prove to be the superbike suprise race.

Because of the fuel delivery issue at higher boosts, those guys in Green Bay are going to install exhaust gas sensors on each cylinder so that they can see how each individual cylinder is behaving, versus the overall average provided by a single O2 sensor. Doing this will allow them more options to tune each cylinder individually.
Those guys keep pushing and pushing and pushing, and will not stop; I feel very fortunate to be part of the group!

I was lucky the opportunity presented itself like it did out on the highway, but you take ‘em as they come.
If you look at the second link I provided and scroll near the bottom, it’ll show that the earlier YZF’s did 10.22, and the later one’s 10.36; that’s scorching, and there's no way I could come close to matching that!
At least not yet...

Sitting....Well, Laying under my 89S4 a few nights ago taking the clutch bolts off for the first time so I can pull the engine, I noticed that there are some nuts on each exhaust port. I assume that these are parts that would be easily adapted to this process....
That gives me an idea!

Off the line, in a typical "drag race", the bike will have a pretty awesome launch.
Some stock bikes are pulling 0-60 in 2 seconds or so...
So it is hard to beat that kind of power to weight ratio.
So in most drag races, even if the car has superior power, and aerodynamics,
it is still hard to catch up, when a bike gets such a head start...
As soon as you get into the triple digits on a bike, or a roll-on race on the freeway,
aerodynamics play an important role. Few riders know how to get their bodies into
proper position. Even so, it is hard to get a bike over 200MPH. They are not very
aerodynamic. So if the Devek white car can pull over 200MPH, I would guess many
of the supercharged 928s will be capable of that or more... So yes, a bike can
accelerate pretty fast. But once you and the bike are both pulling 70-90 mph,
and you hit it, the bike has to push a poorly aerodynamic body through the air...
The 928 is pretty slippery, and if it is supercharged, it has a lot more power
to push with. It takes a lot of horsepower to overcome the force of the air.
So a car with a lot of horsepower, and good aero, will do a lot better at a
high speed race, than a bike. Even so, a stock ZX-9 can do the quarter mile
in 10 seconds (9.97) on stock rubber, etc... And the Hayabusas top out at
over 200MPH. So unless you have one of those supercharged beasts,
avoid racing the 2 wheelers, unless you want to be humbled...

I just ask because a GTS has nearly 70% of that and you can't hardly use that in the real world. Can you??? I mean my meager 220 hp keeps my license on it's toes, ya know? I guess I should ask the Devek folks and Mark A. the same question...- Ruf

As has been mentioned already, off the line I'd expect the results against the bike to be different than they were. I think one of the reasons the guy on the bike did finally let off when he did was because he was starting to get closer to his top speed, and saw that it was pointless to continue. On the other hand, we had quite a way to go before reaching our top speed.

From a dead stop - a Blown shark would have a most difficult time catching a bike. From a roll, thats a different story.
I have yet to be beat on my F3 from a stop - A Z06, Turbo Supra have nothing on my bike. Two of the cars I went up against (Time and Place remain confidential)
The Hayubasa is the fastest production bike out, pulling quarters in 9 seconds and a top end in excess of 200 MPH. One article I read stated a possible TE of 220 mph. I have a feeling if the shark in question went against that bike, there would of been a different outcome. No offense guys -
Still, that is an amazing event (SC slamming a SB) that should go recognized and I give my standard BOO- YA! and 2 thumbs Up!. Way to go guys! I only wish I was there!
Peace

Exactly.
That's why I am guessing that those cars should be able to top 200,
and it is hard for a bike to go that fast, unless the rider is really good.
When they did top speed testing of some of the new superbikes,
they were getting numbers of 175-185, until the rider figured out the
proper way to position his back, and then they got over 200...

When I do/did my high speed runs there are a couple of things I do/did
Tighten the steering damper (On my Old Bike)
Lay my chest flat on the tank
Pull my feet back onto the rear sets (On my Old Bike)
I tuck one arm behind my back
On my throttle arm, I tuck my elbow into the gas tank.
If you think about - If in 87/88 a shark reached 170 mph - 200 mph is easily doable with a supercharger. I don't have a doubt what so ever.

Ya know what is really scary about the work these guys do up in WI/IL?
Its not even winter yet!
God forbid if they sit around in a heated garage with Lienenkugals and deep fried cheese curds tweeking and thinking of more HP refinements!
The nice thing about this HP they are developing is that it is only there when you need it.
Cruisng along the intersate...NAAAaa
On the way to Home Depot...NAAAaaa
Being bothered/challenged by some rice or other domestic pest.....ya NAIL IT! burnout:
Keep up the great work guys!

Yep, if it were a Hayabusa, the story probably would have gone like, well, I hung tough with him for a while.... ahem!, uhh, ...well, ok, that's when we were waiting to start, ...and then we're off and he was gone; doh!
The one regret I have is that I didn't think to pull off at the next exit so that we could've talked to the rider and his buddies. Imagine how that would've been!
I know he wasn't pissed about the race or else he wouldn't have done a stand-up power wheelie after I gave him thumbs-up. I would have to guess that more than likely, he was impressed that a car could do that to him, and probably for the first time; I know I would be if I were him.
But I must say that even after the 30 miles back to Tim's house, my heart was still pounding in my chest from the excitement as we stepped out onto the driveway; I just couldn't think straight. Those who know me would probably say, so, what's new? I'm glad my buds put up with me!
I wish I knew if he posts on a YZF board somewhere, and reported our event.
