Thread: 240sx vs gsxr bike

  1. #1

    240sx vs gsxr bike

    91 240sx with a GTR33 vspec rb26dett: intakes, front mount, MBC (14/14.5 psi), nismo downpipe, hks 3" exhaust, z32 vlsd, gutted to the extreme (i suppose)

    I'm on the freeway, I always drive slow, so i'm minding my own business heading home one night in the middle lane, i see two bikes pulling in behind me, when they caught up, one actually got next to me and started revving his bike at me and then went away, he wasn't that far away after that.
    I think to myself, a bike, yeah right i'll get owned, but then i said F*ck it, no shame in losing to a bike, cause it's a bike!

    Downshifted to 4th should've downshifted to 3rd i think or was it 4th, don't remember, maybe i was in 3rd, whatever i got next to him, he looked over, we both went at it, he was right by my window, and i just hear his bike screaming and shifting gears while he's looking over at me (i wonder what was going through his head) and by the time a truck was up in front of me before "i had to let off" i was up about 3/4's a car to a car length, and my brakes sure smelled afterwards

    This was awhile ago and I don't know how fast i was going as my speedometer isn't calibrated along with my rpms (not as bad as my speedo) and since i don't know much about bikes i called my cousin and gave him a description of the bike right after we ran and he told me it was a 750, but whatever it was it was still a bike and it sure felt great

    that's no telling if it is gixxer 600, 750 or 1000 except certain year they have diff. exhaust, and if you really pay attention to its front fork.

    pretty nice job man, how much power u put down?

    I race my roomate 750rwhp Supra with my SV1000s from 45 up, I beat him pretty good but he said around 140 he was actually catching me..

    would love to see pic of your car

    i have no idea how much i put down, i wish i knew, i sold some parts left over to a guy with a gtr33 vspec, he said he put 306 whp to all 4 wheels..at 12 psi..he was pretty much stock..

    considering he's all/4 wheel drive compared to my rwd and i'm boosting more, i'm positive i have at least more than 306 to the wheels given the mods i have: intakes, fmic & piping, downpipe-exhaust
    not to mention i'm sure my power-weight ratio is a factor as well

    it was probalby a 600, i keep up with those pretty frequently on the fwy.

    600's arent anything. i used to own a gsxr1000 and it was a badass bike. everyone thinks busas are where its at but in reality ive ridden both and seen almost no increase in power among the 2. but as far as your race sick job.

    sounds like a couple things can be taken for facts out of this story.
    1. The tool on the bike is a new ridder and can't ride for ****. (you can tell cause he wanted to race a car, and b cause he didn't win)
    2. The bike was probally an very old 600 in horrible opperating condition. Cause he should have absolutely smoked you. I have been riding for years and allways have owned 600 cc bikes. The new 600 cc bike (06-07) can easily kill any of the older circa 2000 liter bikes. This is of course stock to stock.

    Yes busa's are very tame bikes, look at there riding positions they are more so designed to be a sport touring bike. You sit very upright on them. They just don't jump up and bite you unless you get on that throttle, the new liter bikes are absolutely insane though they want to stand up in the first 4 gears cause they are so tourquey. That is why i stick to the 600 class. 07 ZX6R modded 141 RWHP 63 foot pound of tourque.

    Christ that's alot...our friend has a complete bolt on / commander 636, and he made 144, but with a 30 shot....

    What do the 650's dyno stock?



    And I'm voting older 600 as well

    The 650's such as the sv 650 don't make anything hp wise cause they are v twins and have mad style torque. the jap 600 and 1K cc bikes are inline 4 cylinders that make huge hp with small tourque numbers. Like my bike had 109 hp at the crank stock, then i threw on a powercommander, Full akropovic titanium evo race exhaust (headers, and can weight in at 9 lbs totall), Kawasaki Race ECU, BMC race air filter, Removed all the pollution control devices, and had it custom dyno tuned.

    youre making 140whp on a 600cc? ur funny because a 2007 zx6r is the slowest and weakest 600cc. it barely dynos 100whp stock. so you put on a full system, pcIII, bmc race and dyno tuned and made 40whp? you sir are a bunch of . wait, kawasaki race ecu? you mean that jumper mod u did to for the exhaust flap? oh please...

    my 05 r6 dyno'd 108whp bone stock. i ran my buddies 2006 gsxr600 with pcIII, yoshi slip on, and bmc race from a 40-140 roll and i pulled 2 bikes. doesnt matter about the mods, its truly the rider.

    newer 600cc bikes trap at around 125-130ish depending on whos riding.

    300whp isnt going to make you trap upper 120's in a 240. no way you were racing a newer 600cc bike.

    btw...

    busa's arent fast. gsxr1000 is faster than a busa 1/4mile. i raced a 04 busa on my buddies 06 gsxr1000 from a 60-180 roll (both bikes stock). i pulled 3 bikes. the guy never caught me. maybe its because im 140lbs and the other guy was near 200lbs...

    The race ecu replaces the stock ecu. The jumper mod puts your bike into malaysian emmision specs and only works with the stock ecu. The exhaust valve mod only work onbikes with the stock muffler. Its late ur tommrow morning I will post up my dyno sheets. This is not a bike with **** bolted on like a retarded 18 year old kid buying upgrades. Everything was installed by myself then custom dynotuned by the best tunners in the Midwest. If anyone is ever in the Chicagoland area and would like to see what just under 7k in parts on a zx6r that allows it to put down 141 rwhp sendme a pm and I will be more thenglad to show you the bike and the dyno sheets.

    Sir, with all due respect, I don't understand what you are trying to say, but Busa is FAR from being a tame bike, anyone who club race or do regular trackday with Busa knows its a handful, it has a more relax riding position compare to most supersport and superbike class bike, but only amatuer would claim Busa being a TAME bike.

    and about your 07 ZX6R made 141rwhp and 63 lb-ft of torque? That's really iffy. okay, i will give you that 141rwhp, but AMA formula Xtreme bike makes between 130rwhp to 150rwhp, that's with full factory R&D internal and massive factory support...
    http://www.motorcycle-usa.com/Articl...ID=3215&Page=3

    so okay, i'll give you that 141rwhp, but 63 lb-ft of torque is impossible out of a 599cc bike, NO SIR!!! My SV 998 twin put down 69 lb-ft of torque on dynojet dyno stock, and i've NEVER seen any middle class bike put down more than 50lb-ft of torque to the ground. Most middle class bike put down 44-48 lb-ft of torque stock. Torque figure doesn't lie, displacement and length of stroke create torque, I don't see how you able to make up almost 20 lb-ft TO THE GROUND with 400cc deficit.


    The 650's such as the sv 650 don't make anything hp wise cause they are v twins and have mad style torque. the jap 600 and 1K cc bikes are inline 4 cylinders that make huge hp with small tourque numbers.

    I own 2 V-twin, 650 and the 1000, they have tons of low end and mid range torque due to the nature of V-twin, big bore, long stroke. Inline 4 liter bike makes huge hp and HUGE torque number; I wouldn't call 78+lb-ft of torque SMALL torque number.
    http://www.sportrider.com/features/1.../photo_02.html

    So I can't put everything you said together since none of them makes sense. here is another clue, you claimed u make that amount of power from your 6R, but I don't see u mention anything internal work? stock cam, head, and piston can't make that much of power, and u have the almighty Race ECU, so it should be tailor fit your parts so why would you still need a power commander? It is like you already have Haltech Standalone but you still put on a piggy back S-AFC with it, make no sense at all.

    I am not trying to make a personal attack, but I can't stand how some folks come to a car board and talk all kind of junk about motorcycle b/c they think no one knows what's going on in a car forum.

    here is the last thing I would break it down for you, anyone understand internal combustion engine should know about volumetric efficiency.

    Let's make an assumption, a 599cc natural asp. 4 stroke engine, a 07 Zx6r engine like yours:

    67mm bore, 42.5mm stroke, roughly 95mm rod length, and make peak hp at 14krpm, the engine is breathly roughly 148CFM, assuming that engine can make 100% VE at that speed, it will make 152hp at the crank, so about 141 at the wheel. So, your horsepower figure is possible, but very unlikely.

    I'm calling you out, but if I'm wrong, I will be more than happy to appologize and admit my ignorance.


    for all dyno graphs, here is a good ref.

    Couple things- I own a busa, AND raced for years... I Don't want to break bones anymore doing highsides, so Now I just run the canyons... cornering I keep up with all the guys I raced with on their gsxr1000's, when we come out of corners I can pull on most of them, unless they are sitting at 12,000 rpms... or they roll RC51's, which are torquey too.
    2nd- EVERY dyno read different... I went to one and it showed me having 632 horsepower at the wheels in my GTR, couple months later I'm on a completely different dyno at a different shop and they tell me I have 423.. HKS 2530's, 720cc inj, pushing 20 psi of boost... DYNO's are tuning tools, nothing else. If you get on a hot dyno you can have 200 horsepower differences. Mustang dyno's are notorious for it...

    As far as the 600cc having 141 and 63, it is possible in only 3 ways, turbo, nitrous or a lot of motor work, like pinned block for way oversized pistons etc.

    As far as beating a bike, thats hard, On my modded 2k R6 I made 110 hp and 48tq and an extremely modded Camaro SS hung about a half car back to 160 and then fell off.

    It takes alot to beat a bike with a rider that knows how to ride. But from a 50mph roll, its not to hard to bang the gears out on a bike, so rider only does so much when rolling in a straight line.

    very true.

    Dynodynamics is often 15-20% different depending on the calibration that any other dyno

    That is the most recent dyno. All have been on dynojet bike dynos with the smoothing factor of 5 and level of correction at 0. I have a pretuned dyno chart i can post later today if you still think i'm a complete liar.

    NIce numbers, the only thing people were really doubting was the tq number, I saw 54 lb-ft on the sheet, but not 63.1 or whatever you said. Anyway, PM me the secret as I am going to buy another bike soon, and instead of a 1kcc I may want to do this.

    The trick is that i could have bought a 1098S for the same price that i threw into this bike. But i would still be way heavier. Its all in kawi's new engine with the sky high rev limiter. get clean air in and hot exhaust gas out as fast as possible with out any restrictions like a cat, or the stock air filter. Also make sure to bypass all emission control systems such as pair, air injector valves, or klean air valves. Then drop the money and take it to a motorcycle tunning shop to actually get a legit dyno tune with the timming and fuel adjusted for every throttle position at every rpm range. you may have to ship your bike hundreds of miles away. Its exspensive but the better power to weight ratio will let your bike handle that much better.
