I was running to the store for my wife. I was about to turn off my street when I saw 99 ZX7 pass me. I turned and went in the direction he did. At the end of the street is a stop light and a gas station. I was hoping to catch him at the light. When I crested the hill he was not there. As luck would have it there were four of them at the gas station. I pulled in got some Sprite and went over and talked to them. There were two 2000+ 929rr's, a 2000+ GSXR 750, and the Ninja. I knew I could run with the Ninja because I had that exact bike.
I asked the guys which way they were going because I wanted to see how I would do against their bikes. The guy on the GSXR chuckled and got excited. I asked him what mods the bike had. He said a jet kit and full exhaust. We decided to go from a 50mph kick on the third honk. I have no traction under 40.
We get out onto the road I give the honks and we are off. I took him of the punch by a door. I could still see him out the window. When my converter locked at 80 he made up the ground and had a wheel on me. I evend things up and hit fourth at about 117. I then proceded to pull slightly till about 170. He was at the rear of my door when I hit the rev limiter at 6,700 and had to let off. I wasn't watchint the tack. I just felt it bucking. The Ninja was back past the rear of my car but I didn't look to see him in the rear view. We slowed down and I gave each other the thumbs up. I think both of us were shocked. They all had the WTF look in their eyes. I motioned for them to pull into Lions food, but the 900's had pulled up to take me out. I pulled into the turn lane and they blazed by. And yes he was racing I could hear his exhaust over mine. He would also take a little nose dive when he shifted.
That was the closest race I have ever had. I am still shaking. Those guys were pretty nice. I wish they would have pulled over. I think next time they will think twice befor racing a stock looking 91Z.

 

Do you have an aftermarket spedo? 170?????????? with 3.73's, 2 very capable 10-11 sec bikes? Kinda hard to believe.

 

im getting the feeling the 170 was a Typo...because he was talking about being at 117 to 170 mph, that would be my guess

 

AH I love the nay sayers. I will indulge you. Fourth gear is a .70, multiply that by 3.73, times 170, times 336, then divide by 26 which is the tire diameter. That gives you 5,736rpm. Now add in 8% converter slip. The car is capable of 120 mph with traction. 120 puts a car at 11.20 in the 1/4. I had a ZX7. The fastest I got it at the track was 7.60@92 in the 1/8. My friend had a GSXR 750 that at 160 was half a bike in front of me. Just last month I saw a Hayabusa run consistant 117 trap speeds. That bike is a low 10 sec bike. So some simple math and some past experience makes it all the more believable to me. Besides I hardly ever post kills in here unless they are good. Why do you think I would lie to impress people on the internet that I will never meet.

 

OH! LOOK OUT! Damn I think I just stepped into some bull ****. Now I gotta go wipe it off onto a 91 Z!

 

That was clever. Don't be a hater. I love the " If I can't do it, it can't be done feeling on this board."

 

For their relatively small frontal area and size, motorcycles are actually aerodynamic hogs with a Coefficient of Drag higher than most autos.

From a stop the 600, 700cc class sport bikes would leave all but the most modified race-only suspension equipped car behind.

From 50 Mph up (roughly one third track say, on a quarter mile) a 400 HP car is going to be a good race against a motorcycle that has accelerated out of it's 'zero to sixty' advantage and approaching the aerodynamic wall.

In short, even if the story was made up completely it isn't far-fetched. Gale Banks was hitting 200+ Mph in a 600 HP twin-turbo F-body, the open class bikes are packing around 130+ HP to touch on 200 Mph.

 

I don't know what kind of Hyabusa youve seen, but over here they run about 10.3-10.7 and trap at 135.

 

man your one crazy mother if your going 170

 

Trap speed? No, Top Speed.

 

Rustydawg. That is why I wanted to go from a roll. I know I can't take a bike from a dig. I have ridden since I was 15. Plus I owned one of the bikes I beat. I put the race to my advantage. You can go 180mph with 345hp in an 87 Camaro. There is an article on it in Car Craft. I agree with you on the trap times of the Hayabusa. All of the other bikes out there were trapping from 130 to 155. I was just using that as an exception to the rule. I knew I would get flamed. But it happend. I can't exactly take video and drive at the same time in an imprompto race. We had planed on a 50 roll but it ended up being a 60 roll. I am putting out about 530 at the crank. With the right gear 200 is possible.

 

good run!!

 

Top speed on a Hayabusa is 187, at least that is what cycle world tested it at, they had a showdown between a Hayabusa and a ZX12R, however in the article the ZX12R did 185, both bikes were showroom stock (so the article said).

 

Didn't the government mandate some sort of restriction on that bike and the ZX12 to limit the top speed. I think all you have to do is change the exhaust and mess with the fuel and it will go 200. The fastest I went on my ZX7 was 165 on the speedo. I was at 11,200rpm. I had a little handle left but got scared. The bike was maxed out. My budy on the GSXR kept going. I don't think he had much left though.

 

Do you have this issue of car craft? I would like to see the article, sounds like interesting reading.

 

The European and American Government officials were all over Suzuki and Kawasaki for those bikes, they could have done 200 easy but Europe put pressure on them and America followed saying they wanted a speed restriction of 188 for some reason, the bike makers countered saying "let the consumer deside safe speed" kinda funny.

 

RMK. The more I think about it, I think it was Cheve High Performance. I would have to research it for you and try to find the article. There is a great sight I use for many calculations called www.smokemup.com. That site states that in an 88 IROC it will take 408hp to push the wind resistance of that car to 200mph.

 

good kill...
smart thing though..that u try those guys from a roll

 

this is interesting, i have a very similar engine with some slightly better parts (like pistons), and a little bit more compression (11.5:1)granted i have some tuning issues as of right now, i need to hit the dyno bad. but i even have the same gears (need 4.10s for this cam though) also, the car has a tremec 5speed not an automatic, and some serious traction equipment (SSM lift bars) with ET streets im in the 12.7-12.8 range at about 108 mph. the fact that your pulling like 116mph in the quarter is fairly strange to me. we know that the engine is pushing around 600hp from calculations we did when it was running low 10's in a much lighter race car before we bolted it into my 10 ton 3rd gen.

im not sure, but i think most of that is explained by my gearing problem. the cam makes power from 4400-7000, and with the 3.73's when i shift im dropping like 600rpm below the power band.....and crossing the traps wound out in 3rd gear. Im fairly confident that the 4.10s will get the car into the 11 range (it actually says 4.10s must be used on the cam card, weird) it makes sense though. the cam in this motor is apparently very sensitive to gearing, ive head stories from other guys with similar stuff though, and having a gear thats that far off can cost a second or so in the 1/4.....your motor is almost identical to mine though, so im interested in seeing how you have it setup. the 3.73's must be pretty awesome with the auto trans

 

:sillylol: so tru

 

383Back. 116 is a slow trap speed for my current combo. With traction I am positive it will run 120. I still need some tuning. I would check the trans or some thing. To run 116 in a 3600lb car only takes 385rwhp. I figure I am in the 430rwhp range. I have taken down cars on the highway that consistantly run 118-120 trap speeds with slicks. The car flat flys on the top end. 11secZ has a similar combo to mine. Less head and a slightly different cam (which I have am waiting to instal) he has gone 123.25mph in a 3600lb third gen. He runs a 3.73 and a 28" tire.

 

ya i know my timing curve is off, and my carb still needs some work.....but the car is absolutely nasty on the highway with the 3.73's in, ive had it over 150 in 5th gear (.62 overdrive) and squished the pedal, and it will still put your head in the back seat.

if i shift the car into 4th before the traps, the car will run faster trap speeds (110 or so) but it runs a slower ET, which tells me that there is plenty more power in there, just need to get it out with some deeper gears. If i had an automatic 3.73's would probably be a good gear....but with the 5 speed its just way off.

 

On the sportbike issue. I am not sure if it is still the same but when I bought my 1991 GSXR 100 new the bikes that came into Canada had larger carbs than those in the US. I was told it was due to the California emission laws. Going from 36mm Mikunis on the US model to 40mm's on the Canadian model in that year made quite a difference in performance.

 

Not to get off topic but in reference to the trap speeds just go to a LS1 board. Many mildly modded LS1s run 115+ mph trap speeds. I know some people are prone to BSing but I have seen them trap those types of speeds.

And as far as racing bikes. I have seen a video with an LS1 on camaroz28.com lounge board racing on the highway and the bike couldn't pull on him.

 

Yea, maybe because that was a twin turbo black Trans Am. I have the video

 

Ye, I guess that would do it.

 

What kind of trans work have you gotten done? A stock or even vette servo auto would have limited you well before 170. Stock the tranny will kickdown to 3rd (1:1, not .7:1 ) at half throttle, vette survo it's more like 2/3rds. There is a special DIY mod that won't let it kickdown even with full throttle but I'd really like to know what you got done since that isn't a popular mod.

 

^
I heard this all the time, but my '85 700r4 never had this problem. I hit my top speed in OD (145mph...just wouldnt go faster). I think that only some years have this problem.

Im not going to call BS on the bikes. It seems that your combo is pretty strong.

JimmyMac,
In general, if a LS1 is trapping 115+ they are running very low 12's/high 11's and are 6 speed cars. A lot of people exagerate things on LS1 boards. I get the impression that most people that post dont even own LS1's (which is why I hang out here).

Bikes arent unstoppable...but I sure as hell would be left in the dust.

It would be interesting to run one with a 150 shot on the highway. Hmm, anyone got a bike?

-Doug

 

I agree, ok maybe 115+ takes a little more than mild modification. But there are more than a couple of them here in little Tulsa OK doing it and there are also a lot of BSers.

In any case I think a mid to low 12 second car has a reasonable chance of hanging with a bike from a 40+ mph roll.

 

i've destroyed some ****tier 600CC bikes before with my car.....i even kept up with my buddies 929RR cbr that thing is fast.....but that was from a fast roll at about 65, and pulling up to about 110.....and the kid that was driving it is not the best rider in the world, but thats still pretty impressive considering how fast those bikes are.

and yes, its true bikes are not unbeatable....theres some dude up at NED with a mid-high 9 second 88 monte SS (has plates on it and everything, supposedly street legal )(that thing i s baaaadassss) he wastes dudes on hyabusas or however you spell that...granted there is a lack of good riders around here, but most people only pull those bikes into the low low 10sec range, an occasional 9.9 or so.

i cant really call bs on him though, cause my car isnt street legal but its registered and drive it around on the street lol. cats are for wusses

 

First off the trans was built by Pro Built in Cali. It has a heavy duty drum and spline to handle 650hp. He does all sorts of stuff to the servos and valve body. He also limits the fluid flow with restrictors so you can WOT shift at any speed any gear. Also it has some other stuff that allows me to rev to 7,000rpm with no problem. The trans was set up for my car. It cost me $1,800 so it better kick *** and it does.
The Trans Am in question runs 10.90. It said so on the window. He pulled a GSXR 1000. My car is capable of 11.20 and I ran pretty much even with a GSXR 750. I would figure the 750 to be atleast three tenths slower than the 1,000 or it's not worth the extra $3,000.
A heads and cam, stock displacement LS1 will trap from 117-120. It has been done hundreds of times. Most of the H/C cars I have seen put down 400-440rwhp. The LS1 rocks.
I still have alot of tuning to do. The spark and fuel curve are what it is all about.

 

Hey lethal, I have no dout you are not BSing. Don't sweat the guys that have never driven or ridden in a car with a brutal mid to top end charge such as yours. A lot of these guys are magazine racers, and think that since the mags say a zx9 or whatever runs 10:20's, they should all do that. My bike, (TL 1000R), was supposed to run 10:80's stock. I had a full exhaust on it, a gear change, and I'd bet money on my best day I could maybe run mid-elevens with it. I absolutely destroyed a GSXR 750, and a ZX-9-both of which are supposed to be way faster bikes than mine. I watched a GSXR 1000 go low 13's all day at the track one day. Bikes make all of their ET out of the hole.
I had the same reaction when I posted about me running heads up with a GSXR 1000 from 70 on the highway in my GF's dad's 99 Viper GTS(lightly modded). Anyhow, nice kill!!!!

<b>a 400 HP car is going to be a good race against a motorcycle that has accelerated out of it's 'zero to sixty' advantage and approaching the aerodynamic wall. </b>

I can second this. My dads got an older 950 Kawasaki that can run mid 11's all day at the track. My car barelly pulls a 12 with a high MPH 119-121. I can take him from a 40 MPH+ roll, but off the line? hah.
My car also does over 175 MPH with a simple TH350 and 2.77 gearing. the only reason I cant go faster is because my tach tops out @ 6200 RPMS and if i rev any higher I will float the valves.. lol...

now if i had gearing and an overdrive tranny... the story would change instantly... oh and the blower helps a little too.

 

dude if your running high 12's at 120......nope i dont see it....that should be around an 11.4 even with horrific traction and horrendus 60' times you should be way quicker than that if you run 120mph trap speeds. sounds weird to me

 

what sounds weird? a 2.2 60' time and a 119-121 trap speed? with 440 RWHP? doesnt sound weird to me. well, maybe a little...
keep in mind i dont make power will 3500 RPMS+. My 60' time is 2.2 with ZERO tire spin. the car launches on 2.77s like it has 140 horsepower. when it finnaly picks up... somwhere around 40 MPH... (3500~ rpms @ 40 MPH... 65 MPH in 1st gear @ 6200 rpms)
it goes the limit. yeah with a gear change i would be in the mid 11's... but for now... *sigh

how about monty's 10 second 1/4 mile with a trap speed of 160 MPH? that 8 second territory. sound weird?

there are lots of weird things. like whys the sky blue? thats weird.

 

Hmmm....Those bikes are fast as hell, and at first I was skeptical, but if your really puttin' down 530hp, then I'd believe it from a roll, from a stop, I'd doubt that. Good kill.


Tim:rockon:

 

im pretty good with alot of higher math, physics and dynamics....and i just cant reason that out.....even with what you said, if you had enough power to push the car that fast in the 1/4., your ets would be alot lower......also even with very steep gears like 2.77's the tires would break lose because the force would overcome traction, or the engine would nearly stall. even in these cases, the et for that MPH should be way lower...ive never seen anything close to that far off

 

Thanks for the backing guys.
King. Have you added any thing to your engine thats not in your sig. Unless I missed something. That is a ton of mph for that combo.

 

yep....the only thing i can think of thats even similar to that is when a much faster car shuts down before the traps and runs like an 11-12 sec pass at like 80mph....but thats going in the other direction from what this guy is talking about

 

<b>Have you added any thing to your engine thats not in your sig.</b>

well ive done many things and un-done many things since I made the sig. maybe its the G-tech? ive been told the MPH is a little high.

oh and the HP number is wrong. I was pushing well over 530 Horse at the flywheel with the blower. that number (420) is without the blower, at the flywheel. even with the blower i couldnt spin the tires very easilly. they would spin for less than half a second then it would bog until 40-50 MPH. my gearing is the main thing holding me back at this point.

 

My G-Tech says I run a consistant 12.30@126. I would like to see how off the mph is. I have no traction under 40 at all.

 

First of all, bikes aren't that quick in the first 60 feet - most run about 2.0 without a wheelie bar. I have seen idiots at Englishtown flip bikes on the line because they were too aggressive on the launch.

They really rock between 60ft and the 1/8th, a lot have enough acceleration to pull the front wheel up while going 60mph (or if you lean back).

However, above 100 most bikes don't have too much poop left - aerodynamics is the main problem there.

Think about it this way - a stock L98 third gen can hit 150mph with 3.27 gears, running in the low 14's at 95mph+. A Hayabusa tops out about 190mph and runs in the low 10's at 140mph+. Now if you had the same acceleration in a thirdgen you would have about 750hp and the car would be able to reach over 225mph (with proper gearing).

I never had the chance to race a fast bike from a 50mph roll, but unless it is at least a 1000, I'll hand most their behinds on the bottle. I'm sure a Hayabusa would kill me. Then again a 383 would actually cost less than a Hayabusa, so there you go.

 

LethalRacer, after my mods this fall I ran a 13.11@121.4 mph on the g-tech. Looks like our mph is not that far apart. I launched real easy with no wheelspin. The consensus on the board is the g-techs are about 3-4 mph higher than what you would get on a track.

 

dude, a 13.1 at over 120?

you people need to go to the track and stop f*ckin with these gtech things.....how can so many people have trap speeds that are so far from the ballpark with their et's? its not logical, it doesnt make any sense.....120 is in the mid-high 11sec range easy. if your running 120 in the 1/4 i dont care how bad your traction is your gonna be well under 13 sec.

 

383backinblack. I did not get my car ready in time to get to the track before our busy season. Now it is winter up here so it will be spring before I get there. I am not sure what to make of those numbers. I did say I started very easy with no wheelspin and the g-tech mph is 3-4 mph high. Say it will run 117 mph on a track and with traction the et will come down quite a bit. That is all I have to go by for now. I think the mph tells me there is some hp there.
