More food for thought:

According to the tests posted for those bike, some of the new PDK cars (0-60 in 2.7) can probably hang pretty well in the stoplight to stoplight battles, particularly against less skilled riders.

 

Earl - agree it takes some skills to run under 3 seconds on a bike without smoking your clutch, keeping the wheel on the ground, launching at right rpm, etc. I remember the vid of the guy drinking a can of soda while doing 2.9 in the porsche.

 

Being on both sides of this discussion and having ridden Motorcycles for 40+ years now, as well as being a Porsche nut, Widowmaker owner and a driving instructor for various local race series and track day organizations, the other thing to remember is that the Hayabusa and ZX-14 are old news and STOCK, are not even close to being the fastest Bikes out there anymore... These days, the STOCK BMW S1000RR and the Kawasaki ZX-10R are the top of the heap.

For example, a STOCK BMW S1000RR runs as good as a 9.4 at 156 mph in the quarter. With bolt ons (pipe, Power Commander V) and stock wheelbase, it has run as low as a 8.9 at 157 mph... With an extended swingarm, it will run 8.49 at 158+ (they have recently gone 162 mph)

Stock Wheelbase, bolt ons:

Extended Wheelbase, same bolt on's:

A stock BMW S1000RR with a gearing change has gone 202 in the standing mile.. no pipe, power commander, filter.. zero mods other than a $25.00 sprocket change.

A stock (straight off the showroom floor) BMW S1000RR can do 0-180 mph in 15.7 seconds. With bolt ons, I think 0-180 can be done in 12 -14 seconds (bearing in mind that with bolt ons, they get to 160 mph in 8.5 seconds)


The caveats though are:

Rider... Anything other than an extremely skilled rider cannot get the maximum out of these Bikes.. 98% of the riders I meet that have Liter Bikes or Open class bikes (Hayabusa, ZX-14R) can't use them properly.. Most of them have never gone full throttle on their Bikes, because quite frankly they are scared of them... I have a buddy who has been riding for 30+ years and owns a ZX-12R, a Suzuki GSXR 1000 and a ton of other Bikes and Cars and I can beat him in a straight line when I am on my Triumph 675 Daytona!!! (116 RWHP vs. his 160+ RWHP).. because he just cannot ride as well as I can, he can't shift as fast as I can (clutchless upshifts are something he can't master) and he's scared of the Bike.

Weight.. A 270 lb rider on one of these Bikes is a LOT different than a 140 lb rider.. The power to weight ratio goes to hell when the rider is "heavy". Bigger riders screw up the aerodynamics if they cannot tuck behind the windscreen... a smaller rider can get out of the way and consequently the bike is faster up top with a smaller rider.

Roll ons... Above about 140 mph, Bikes have the aero of a Combine Harvester ... Rollons are hard to get right on a Bike... You have to be able to keep the front end down, be in the exact right rev range and be able to shift perfectly. If not, you are dead before you even begin.

My ZX-10R utterly destroys my buddy's stroker Hennessy Venom 650 (630 rwhp on a DynoJet)... not even in the same Universe.. By destroy, I mean from 60 mph - 150 mph, I am 300 yards gone (and I am 220 lbs and have terrible aero characteristics... Ok.. I'm fat ); BUT.. if I am not in the right gear or out of the correct rev range, it takes a while to haul past him and above 150 mph he begins to pull on me quite quickly.

Bottom line is that high HP Cars (800 RWHP+) will always win if the speeds get above 150 mph.. A well ridden BMW S1000RR or ZX-10R will always win if the rider is GOOD.. not competent or decent, but actually good from lower speeds up to about 150 mph. A 208 Flywheel HP (that's stock with Ram air added) BMW S1000RR with a 140 lb rider is hauling 2.78 lbs per HP around.. A 3500 lb Car needs to be at 1250 HP (flywheel) to match that.

I love both my GT2 and my Bikes.. The GT2 is my favorite Car ever and the Bikes are an adrenaline rush like nothing else on the roads. If you can beat a properly ridden Liter or Open class Bike, it means that you have one f@cking fast Car AND you can actually drive it!

 

Best post yet. Bravo!

 

yeah, great post 80shilling, the beamer is a beast!

 

I agree but when start serious modding the busa and gixxer1000 would be way to go!!

 

Absolutely.. The 'Busa and ZX-14R have 1.3 and 1.4 liters vs the BMW and ZX-10R and GSXR's 1.0 liter.. Add a Turbo, bore/stroke kit, Nitrous etc and the 'Busa and ZX-14r become otherworldly. I was just pointing out where the state of the art is today in terms of stock performance..

 

agree +1

 

U didn't get my point bro

I noticed that most of shops/buiiders make much more mods for Suzuki ( Busa and gixxer1000 ) more than Kawasaki, Honda and Yamaha bikes

 

Milou, you keep on mentioning 1/4 mile times. Busa will win in that scenario. However, most runs are rollons from 60 mph. And in that scenario, it does not take as much power as you think to beat a stock bike. Fact is aero takes a huge toll on bikes. once over 120 mph, the car has the advantage.

 

Most of the races we do are from a dig and go to the 1/4 mile. Whoever gets to the end of the 1/4 mile the fastest wins and gets the money (or a big smile). We also do roll-on races too, but nobody likes to do a 80 or 90mph roll because if you do it from a lower speed, you get more time to race (they seem more fun). I'm sure at a 100mph roll the car's aero and hp advantage can push the race in it's favor.

http://www.youtube.com/watch?v=lIDk4hERnpw I've posted this video before but here it is again. My Z06 had around 650rwhp (it dyno'd 640whp on a 100 degree day). The car weighs 3200lbs and the race was started at 85/90mph because I was having traction issues during that cool night. The rider I went against is 200lbs but VERY skilled and well known in these parts. His ZX-10 was I believe an '04 and he had an exhaust and power commander. You can see how he was clearly able to walk away from me and keep on pulling. The only reason he stopped pulling and I blew past him was because he hit his top speed in the mid 180's while I kept accelerating up to 200. A lot of these high hp Porsches have a GREAT top end pull and can accelerate from 180-200 pretty quick so if a Bike is ahead of you or even with you and it hits it's top speed, you will pull him hard and it seems like you are destroying him when in reality he just topped out (you can consider it a kill I guess but you are not really racing anymore since he topped out). If I had maybe another 150whp on my car then I think that would have changed the scenario. But keep in mind this is an old ZX-10 and the rider was no horse jockey. The Z06 is lighter than a Porsche Turbo and RWD. It's 5th gear does suck but because I had 680RWTQ I would be able to accelerate out of that dead spot within half a second so that it kept pulling hard all the way to redline.

Bottom line is you can beat a bike on top because they are at a hp, aero, and top speed disadvantage as long as you have a ton of hp (750rwhp+?) and perhaps the rider isn't a seasoned racer. If you start from say a 60mph roll, the bike should pull you so hard that it will take a while to catch up to it once it's pegged at it's top speed.

 

I swear that im saying that for a years and no body damn listen!!!!!!!!!!!!

I believe if u dont have another passenger with u will beat him fair and square

The 5th gear ( +165mph ) on the C6ZO6 really sux

BTW....What mods in ur car??

Nice ran Mr- Siffredi

 

ItalianStallian,
Great video and run!

I also believe you would have pulled him if you had not had a passenger and that terrible 5th gear. However, many modded TTs have been converted to RWD and weigh less than 3200 lbs with some additional reduction.

I think many times when these crotch rocket jockies get pulled it's because they underestimated the car they were facing. For instance they select third gear to start a roll rather than first or second or even give the car the jump...

 

The passenger was a featherweight at 150lbs but that definitely would have helped. Yes the Z06 5th gear is complete BS (we have 6th gear for economy!)

And yes a Porsche weighing in at those weights with RWD will be very very devistating.

Unfortunately, almost no bikes that actually race (go to race meets and challenge you) are bone stock. It is very easy and sneaky to get extra power out of bikes. 50hp on a bike is like you adding 150hp lol and bikes get the power to the ground. Plus most guys who really race know their bikes like the back of their hand. The average rider on the street won't showcase what these bikes can really do.

I'm a car guy and I want the cars to win. Bikes are unfair lol. But a few of my friends have bikes and no matter how much we mod our cars, they can make a little tweak here or there and blow us away. 8 second 1/4 miles are pretty much untouchable.

BTW for those asking about running below the 80mph zone...I tried that and it was embarassing. He would pop wheelies and just walk away from me and keep on pulling. In fact, even one of the higher speed races where we started around 90, the guy was popping a wheelie just to show off lol. We did like 15 runs that night. BTW, there was also a ZX14 that raced me. I actually beat him but couldn't dream of beating the ZX10. Shows the difference from one rider to the next.

 

In the 1/4 mile busa will not win, it will be running alone.

I started this discussion just because a lot of people in this forum believe that their exhaust/ECU/modded turbos car can beat a bike.

A Hayabusa with just exhaust/ECU is faster than the Sledgehammer, i'm using this car as an example since Switzer is the only tuner on the forum who posts time resaults.

I'm sure that there are some cars out there that can beat a bike even from a dig, like the TT galiardo, doing 9,1 in the 1/4 mile.
The point is that a Hayabusa with minor modds and pump fuel is crazy fast and with a sprayer is unbeatable, the last i PBOXED did 100-200 in 2sec flat.
I don't want to create conflict i just want to be realistic.

Talking about top speed a stock bike will loose to a modded turbo. Modded bikes with longer gearing ($100) can exceed 200mph very very easy.
I stopped posting because Scott took this conversation a bit personally
