I post this here because it ain't gonna happen without FI.

Got a guy I work with who is cocky. He seems to think any 1000 CC bike would slaughter any street car. In most cases he would be right, however not all as I have seen them beat by cars before.

This race "may" happen. There's a lot of variables. For one, my pile is not running yet. I'm still about a month from turn key and tune and working out the inevitable bugs. But he is in the process of selling a bike so he can get a GSX R1000. He is a novice rider, and the bike would be stock.

Just asking what power level would be needed to beat him from a 40-50 MPH roll?

My car is a 6-speed. Don't know what power it will make yet, but I am hoping around 1,000 at the tire. Would that be enough?

Weight and traction are going to be the deciding factors.

The higher the roll the bigger the edge goes to the car. A bikes drag coefficient is horrible, think hummer


A 145mph car will be right there or take most liters from a roll on the highway. Rider on the bike is a huge deal though..... Like huge

Yup.. Seen 650whp mustangs beat up on litre bikes. The rider was total dog **** though. A good and i mean GOOD rider on a litre bike from a 50-60 roll will give a 1000 ish whp 3400lb car a run for its money.

Agreed, had those exact numbers in my head, air shifted bike with boltons you're gonna need 900 at the very least

I would assume the weight of the rider would play a role here as the difference between 150 lbs and 250 lbs would affect the power to weight ratio a lot more than in a car. You could also bump the hp of a bike by 50 hp and it would have a similar effect(meaning significant:not comparing it to the weight difference between 150 to 250). No experience on my part, just doing the math.

My car weighs almost 4k lbs, and traps right at 140
I put multiple car lengths on an average rider on an 05 gsxr 1000 a few weeks ago from a 50 roll

It's fairly hard to not wheelie in first at 50, and 2nd will be starting too low for any newer 1k
A good rider should have outran me, this guy wasn't one of them

Biggest factor on a litre bike is if the rider has the sack to power shift.. I had to re learn the whole bike after my ***** dropped. Few guys in my experience ever get to the point of turning the throttle all the way back and never letting go until the top of 6th.

I raced a few novice riders from a dig and destroyed them with my 10.0, 136 trap car. If he doesn't drag race the bike at the track, then going from a dig is usually the way to go IMO. Very few noobs can launch a liter bike effectively.

1000RW should walk a stock liter bike even with a good rider from a roll...

Little less power... You are in for a race if he has exhaust/etc..

If he can't ride very well... 750Rw could take him down, or less. LOL

Rider matters way more than what it takes to beat one. But 1000RW "shouldn't" have an issue.

Seen some real stupid people out there.. But ultimately your right. Two experienced riders/drivers in boost (car) and power shifting (bike) depending on the weight of the car. The car should win closely followed by the bike. Really and truly though this question is way to vague to answer in one short sentence.

Yep... It is why I had a few sentences and should have went farther in detail. LOL

****, I raced a 1000CC bike when I had my 408 making a little north of 500Rw.

He jumped one race and pulled me... Next race he let me leave just a hair early... He pulled a couple cars and I ran him down and passed him. LOL

I'm not stupid, I've owned bikes... That shouldn't have even been a race but he couldn't ride.

I'd go to the lengths to say if I raced a stock 1000 from a 50 roll and got beat with 1000Rw (what I plan on making before I upgrade injectors) I'd be a tad ticked off (and surprised). LOL

My buddy at work drag races a zx14. Its got a stretch and gearing change i believe, rest is stock. 200-210 hp bike? Hes been 1.40's 60's and 8.9's at 152. He is a good rider
I dont see a liter bike stock outrunning a 1400cc bike so figure mid high 140's traps?
My 3800 lb car will trap 145 with 720 whp. Th400 auto tho. Traps 154 around 900-950. I went 8.87 at 154 around 950 whp so outruns the zx14. Not sure a roll would be any different as i look at trap speeds
So a comfy 800-850whp 6 spd fbody should do well against well riden 1000's imo. 1000 whp should pull easy

The car weighs 3440 (without me in it). I weigh 185. The bike rider is probably about 200 lbs. He is not experienced to power shift and my guess he is not a "stellar" racer. He has had some bikes in the past (10 years ago). He hasn't ridden in 5 consistantly. Doesn't sound like he has done much racing even when he was active, but he does know how to go through the gears.

Although I don't have experience driving 1,000 RWHP, I do have a LOT of experience street racing both from digs and rolls with 700 RWHP.

The car has a boost leash boost controller. The "plan" is to set it up so I get full traction in each gear (as it is boosted by gear and you can setup how much boost you want in each gear and the rate at which that boost level comes on). So, I may not have a true 1,000 RWHP at 50, it will be whatever speed allows for full power. This is still all theoretical, as the 1,000 RWHP is a "guess". I will say with my setup, I'm gonna be very surprised if it isn't at least 875 RWHP. But time will tell for sure.

this is interesting especially with the 40-50mph roll. Like previously mentioned, it will either be too slow to effectively launch in 2nd OR the rider will have to have some nuts to launch that hard in first and keep the front end down. I am an okay rider with regards to straight line. My buddies 08 GSXR 1000 with a 6 inch stretch and air shifter allowed me to run 9.90's and I weight roughly 250. Smaller guy and a better rider was able to run 9.10's same day and same bike (my buddy let him run it to show what it could really do and yes, he let my buddy ride his bike). Driver experience and weight is huge, and the drag of a bike around 145 starts taking a toll. Stngkiller's old 4th gen with a turbo setup would be able to give the liter bike the kit from a roll and he could still go around it. with anything above 800 rwhp and a good setup (traction etc.) you should be able to take the liter bike from a roll. ***In my opinion***

That's a win in the bag.. Especially if hes not power shifting the bike. Not riding in 5 years = Short shifting and babying those shifts.. It takes consistent riding and familiarity with the bike to do that. A few years ago i hoped on a buddy's 13' R1 and couldnt believe how fast the bike felt.. It would have taken at least 3 days of riding to get that comfort level back and I use to be RECKLESS on my ZX-10/GSXR 1000's

You take two good rider/drivers, and traction is available

A true 145mph car is gonna take the liter. Bike may get a jump but out the back the car is gonna roll it up


Not all liters are created equal BTW, best watching yourself next to a BMW


Want to see how bad a bike aero is, just look at there 1/8 to 1/4 mph splits

Most bike guys think they are invincible, those are the best to roll up to lol

I've gone 9 teens on a stretched zx10, all motor, foot shifting it
The owner of the bike could barely get it into the 9s
I'm about 50 lbs lighter than him, and he was afraid to launch it hard

If you know what you're doing a mid 140s trap bike will hurt a lot of high hp guys feelings, 9/10 people that think they know what they're doing are still pretty poor riders

SpeedJunkee

I'm not a bike expert but I KNOW about the BMW bikes. They are badass, and I would be posting this if it were a matchup between me and one.

I love nothing more than to quiet cocky individuals who believe that can't be beat, so I hope rolling up to this guy can put him in his place

Thanks all for the info!
