Street Racing & Kill Stories - 630whp 03 Cobra vs Beans GSXR-750 (Vids)

Met up with an 03 cobra to do a few runs.

Cobra moves out!

Enjoy

that was so sick looking when you lifted the tire from the 40 roll! lol

good races... love the clap at the end hahaha.

That's one fast cobra, good riding on your part. Great vid

Looks like Cobra was getting a tad warm by the 3-4 60 roll.

Good runs.. I actually thought you would pull a tad harder.

Great races! I'm glad the weather held and you guys were able to meet up. I think the drag radials on the Cobra must be toast, he usually hooks well from 40. That said, my money is on the bike all day from a 40 roll, even with traction.

Nice riding

Good races!

Nice runs, guys! Looks like the 750 has the edge in all but a top speed run. 40 was rough because of the traction issues but the 60 rolls were great. Gotta love a cammed TS Cobra. :D

Givem the beans old boy! Pretty good ridin Beans... finally someone who tucks in!
That Cobra was hummin on the top end run!

Might be a dumb question but what does it take to actually pull a 600 or 750 bike before 140mph? Almost every video I have ever seen the only time a car pulls is above 140mph area

If i had to guess... to pull beans before 140, you need something that traps around 135mph and can be driven. My buddies 403 trapped 127-128. This cobra id say traps around the 131-132 marker.

Good runs beans.

Whos cobra is this?

The starting speed will effect the outcome alot.

fbody83's Cobra

nice runs and great riding beans!

I was actually shocked how well that cobra stayed with the bike on 60 rolls

Ah ok i thought it was a locals car that makes about this power. Nice runs.

Awesome video

After my car gets back together i wanna race the cobra n a rerun with u beans should be good

The normal 40 and 60 rolls SRZ

The normal 40 and 60 rolls SRZ

There are so many variables that come into play that it's really hard to peg a number to it. You could have different outcomes with different bikes, if both were well ridden, but there was a significant weight difference between the riders. Some setups have much better powerbands and some cars are geared better. Also, older bikes won't be as fast as newer ones.

When we set PSM up against cars we always shoot for a 60-65 roll to start to give the car a better shot right ofF the bat. If the bike loses that then 40 is always fun to watch.

If I wanted to build a bike killer then I'd personally start with a C6 Z06 and do 40 rolls in 1st gear :devil:

The normal 40 and 60 rolls SRZ

My stock 600 traps 104 in the 1/8 to give you an idea, but I only trap 127 in the 1/4 comparatively (numbers from a 2500 DA at LVD). Cars vs bikes are a bit of a lopsided race in this sense, particularly because they pull much harder from a first gear roll than their trap speeds indicate. Around the speeds where a 600 and 750 are running through the 1/4 traps is where aerodynamics are starting to take over, and that aero has a smaller effect on a big hp car than the bikes. This is why you see a lot of 600's and 750's getting run down past those speeds even if the bikes cranked out down low. The higher you start, the less the bike is gonna get out and the sooner the car is gonna pull past it.

In my personal experience, it takes a solid 130+ mph car to hang with me from 40-130, maybe 140 depending on the car. And even then I'll often get out a little down low with the car starting to come back around 120. Where they catch me depends on the car and how close it stayed down low.

With a 60 roll (me in second), on the other hand, a high 120's car will hang with me to 130, then start pulling around 130+. I'm only gonna hang with a 130+ car from 60 for a short time, then it'll start pulling away by 115-120 (or sooner).

This is my personal experience as a "skilled" 150-160 pound rider. Take all numbers with a grain of salt because like SRZ said, there are a LOT of variables for both the cars and the bikes (riders, drivers, gearing, power bands, etc). Let's just say if you've got a car that legitimately traps around 120, it's not gonna be good for you if we meet up. If you're around 125, it likely won't go well unless we take it to 140+ speeds. If you trap 130+, though, things will be interesting and it's gonna get ugly for me past 130-135 (or sooner depending on how high we start and how high you trap).

I know the aprilia i pulled after around 125 is supposed to be a 133 MPH bike but the rider SAID he was short shifting, either way it was a dead even race with him letting me get a small hit for the turbo to spool. I dont see my car keeping up with beans or even PSM from a roll but id give it a shot! Any roll is good with 2.73 granny gears lol.

Sweet thanks always was curious about that. Your bike is moving 104 in the 1/8th that's crazy didn't even know older 600s could do that

Let me know if you're ever in CT.

Yeah, the low to mid range acceleration on 600's is pretty impressive compared to what most people think. A lot of people just like to look at 1/4 trap numbers and gauge results from that, but with bikes it doesn't really work out that way.

104 is movin, but speed traps around where I'm topping out first and into second is where the acceleration would really show. First and second gear from a dig/low roll is where a bike like mine shocks the hell out of people, not the launch itself, but once the clutch is fully released through the rest of 1st and 2nd. By mid 3rd and into 4th I've sort of evened out with a car that traps similarly, which is why a 60 mph second gear roll makes for a good run with a high 120's car up to 130 or so; it takes away that first into second gear acceleration advantage.

Thanks for the compliments.

FBody83s Cobra is super clean, and as you can see from the 60 rolls it has some some legs under it. Cool guy, had fun racing him and look forward to more runs when he hits it with more psi.


If i had to guess... to pull beans before 140, you need something that traps around 135mph and can be driven. My buddies 403 trapped 127-128. This cobra id say traps around the 131-132 marker.

I'd agree with that. On a clean 60 roll i think it'll take a 133-135 car to be out in front at 140. A 630whp Cobra can be in this range, and when heat wasn't a factor he stayed very close and was starting to walk by 140.

From a 40 roll it takes a good deal more power than a 60 roll.

Sounds good let me know when you're all set. You know i'm down whenever.

If you want to set it up let me know, it's all in fun man. I'll give you whatever race you want if you want to get together and do a few pulls.

PSM rides the piss out of that thing.

Sounds good to me. :cheers:

My car is under the knife as I'm typing this for a "killer chiller" install which should help my intake temps. Might not be done this weekend but should definitely be all set for next weekend. I'd like to run Beans again to see how much of a difference it makes so we should all meet up.

great runs. Seeing as im slightly lighter than most cobra's (and the same power as the one you ran), this race gives me hope for when i run my buddies 05 gsxr 600. its bolt-on/geared so we'll see

Sounds good man, text me when you've got it all set and Joe (quick01ss) and I will figure out a time to get together.

You should pull decently from a 60 roll. Make sure he starts in 1st gear from 40. If he does it'll be tough to catch him below 120-130 if he's a good rider.

Cool i still hav prob 2 weeks till im set had to fix a head gasket leaking then after that tune it

I wish i could find a few bikes to run that did not have d-bags for riders. My Cobra makes 672rwhp and weighs about 125lbs less than a stock cobra so it should be interesting running a 750.

Come to the RI/CT meet in 2 weeks. Probably in central CT.

I'll run you, and i'm sure there will be other cars there that would be down.

Dig, rolls, whatever you want as long as it's not a 75+ roll.

Check the meet thread.

I ran a 09 cbr 600 with intake/exhaust and tune from a 30/40 roll and held with him and pulled him up top after 100mph. Bike was also geared shorter. with a 50 roll same out come. Don't know if the cbr's are just a lot slower then the gsxr's or r6's.

Did you post videos? I remember seeing a red fbody with a centri blower racing a black bike.

Riders make a big difference. That CBR should be in a similar range as mine stock for stock (perhaps a rider's race) but with the minor mods and gearing, he definitely shouldn't be any slower than me from a 40 hit in first (I'd say significantly quicker through the first few gears if he can keep the front end down on the hit). Gearing does hurt their top end a bit, but we're talking 120-130+ unless it's geared to the moon, not 100 mph. Again, the rider makes a big difference, both skill and weight. I could definitely see the race going that way if you're over 500 depending on the rider. I could also see one running away from you up to 140 or so with modest gearing and a non-heavy, skilled rider, but that's harder to find.

Bottom line, if you're over 500 to the wheels in a 3,500 lb car (or less), you're not gonna have trouble messing with most 600's on the street from any speed the way 95% of them are ridden. But watch out for that 5% from a lower roll. That's where these bikes surprise people.

Your a much rarer breed then you think lol. Me thinks more like 1%.. not 5%. My car makes a hair over 400 and i dont have any issues with most 600s. Its sad... but it is what it is

I was attempting to be conservative and modest, but I think a 1-2% estimate of riders who can do their bike justice - even in a straight line - is probably accurate. :angel:

Then there's the maybe 10-15% who can do a decent job, just well enough to make you think the bike was being ridden balls to the wall. You see a decent amount of them in videos because they're typically the ones that agree to setup races on video.

But race 20 random 600's you see cruising around on the street from 40-140 mph with even a 450rwhp car like yours and you'll likely win every race.

Nice runs, guys! Looks like the 750 has the edge in all but a top speed run. 40 was rough because of the traction issues but the 60 rolls were great. Gotta love a cammed TS Cobra. :D

FWIW, the difference in the 60 rolls was how hot the Cobra was. I think my riding and his driving were pretty consistent between the 60 rolls.

That first 60 roll was the first time the Cobra was really pushed and he was right with me the whole way, slowly starting to walk after 120-130.

The other 2 60-140s the car was hotter and i pulled a few lengths.

We gave it 10 minutes of highway cruising and he stayed close on the 60-160 to about 120 and then started reeling me in, with a serious pull up top.

I can't wait for him to get the killer chiller done. That car makes sick TQ so i think once he can keep it cooler he's going to stay even with me for a few seconds and then start walking out. Should be sick.

it really is sad. The few 600s ive played with so far, have either not been able to pull me from 40 to 120 at all... or have pulled me a few bike lengths to 120 and stay in it way too long and i just come rolling by them like there stopped. Thats what happened with the gsxr750 i raced. Hed pounce on my from 50mph, maybe put 2-3 cars on me, by 145 im rolling by him again like hes stopped. Then i race beans, and he hurts my feelings... to the point where i dont even bother shifting the car hard.

Yeah, I can't wait for that to get installed so he and I can get some more runs in. I've been hoping this whole time while he was doing the build that the end result would be me getting beat from any start, and he's getting very close to that happening. It likely will once that thing is installed (if he can find traction now that his tires are shot, anyways).

It is definitely sad, but does make it more fun for me when someone gets a bunch of runs like that with other bikes and then intends to romp on my bike. :D

Its also sad i would need headers and a 75 shot to legitemately beat a stock 600...

Did you post videos? I remember seeing a red fbody with a centri blower racing a black bike.

I believe the guy with the 76mm turbo Camaro posted up a vid. I ran the cbr on motor a long time ago but lost about 2 car lengths when he was stock w/ gears and slowly started to creep up top when he ran out of gear @ 130mph. My car trapped 121mph on a hot muggy high D/A day. I know that 750 would rape me.

I need to keep my head about 2" lower.

My 1-2 shifts have always sucked balls. I'm going to add a quick shifter in the interest of increasing clutch and trans life while making the bike more consistent. I don't think it'll do much for me after the 1-2 shift but it should be faster from 40, because i'm not getting 100% on 40 rolls.

the quick shifter mod is only a stronger detent spring and slightly off set detent arm.. wont do much for ur 1-2nd as u have to go thru neutral.. after that clutchless shifts are alot smoother with half the effort.. problem is those new springs tend to break. ive done a bunch of these and its really not worth it. practice getting that foot up faster or go gp shift

I have a GP shift now. By quickshifter i meant the dynojet quickshifter, which is just a fuel cut through the PC3 so you can leave the throttle wide open and shift clutchless. No hardware, just electronics.

i dabbled with those too.. not much of a difference honestly. ive been messing with the pc5 and auto tune on a few bikes lately and thats deff the way to go. makes tuning on the fly as easy as flipping a switch.

dyno it and find what she likes for afr's thru the power band.. set the afr in each block for throttle position and your done. thats where i would spend the money. i actually ordered one for my 10 and plan to just sell the pc3

just as an example.. 08 gsxr 1000. stock (on a low reading dyno) made 154. slip on yoshi and pc5 with AT. after playing with it i managed 168 with around 13.4 wot through out the 100% tp. i also played with the cruise blocks and leaned her out a bit.. he says hes picked up big gas milage as well and 3rd gear roll on wheelies.

Some timing advance to get those numbers?

PC-V has ignition control right?

no thats a separate option just like auto tune. pc5 is deff the way to go. i have only messed with the ignition advance option once. pulled some timing for nitrous on a 05 r1. thats about all the experiece i have with that option.

the 08 gsxr stock tune was 12.4 afr wot.. the base map i used from the pc5 brang it to 12.8..i leaned her to 13.4 across the board at 100% throttle. didnt wanna push it much more than that... i blocked off the emissions and disabled the SET valve and also modded the airbox a little. but other than that its just a slip-on.. surprised me withthe power it made

sorry i just looked at the sheet.. the stock tune was way lean.. 14.1..the pc5 base map buryied it down to 12.4.. i brang it to 13.4 and that was the best power curve.

also remember that the auto tune can be set to a toggle switch and it has a learning mode. you can go between two maps and the learning mode. learning mode being it changes with the weather and finds the preset afr that is programmed into it no matter the weather..hot or cool

Interesting. It's not available for my bike. Probably wouldn't spend the $$ anyway.

Maybe on the next bike. :)
