06-07 ZX-10R Drag Bike ?'s : Kawasaki ZX Forums: Kawasaki Ninja Forum

THIS IS THE PLANNING STAGE

I have taken my 10 to the track and ran numerous times. The only performance mods have been: K&N Air Filter and race baffels. No engine or electrical work has been done and my quickest time was 6.76 in the 8th and that day it was around 80-85 degrees and it was humid as hell (in florida).

So now I am gonna get a 10 with low miles and in great condition and make it strictly a drag bike. I am wanting to use the OEM engine block (Kawi's racin program wont let u use any other than theirs).

I am WANTING to run it with: NOS (wet), Turbo, extended swing not extentions, PC, ignition modual, aftermarket heads, cams, valves, pistons, rods, crank (baisicaly everything IN the engine will b aftermarket). For the tire I am wanting to use a 7" drag tire.

Im not going to put it together, im just going to buy the parts so someone else can. I have so many ?'s like...... How much boost can a OEM block safely handle?....... For the swing arm how long would b a good lenght to keep the front down and so i dont spin off the line? Compression Ratio? Type of fuel to use? Gearing?

As u can prolly tell i am wanting to go fast as hell. Thats y i am planning this out vs tial and error. I am deff wanting to wax 14's and busas.

Would anyone know where I could find out what the thickness is between the cylinder walls? Thinkn about boring the cylinders out to 78mm (1051cc), with a compression ratio of 13.5:1. I know I could do it..... Its just that I am going to have a turbo and dont want the walls to be TOO thin.

n.c.rider · 09-01-2009, 10:55 PM

if you want to turbo it, you will need to drop the compression to around 9 to 1. if i was building a 10 i would build a 3x4. 3 mill overbore, 4mill stroke and about a 60hp wet shot with a tim hayes conversion clutch. for what it will cost to turbo it you could build the motor and have money left over.

Mug_13 · 09-02-2009, 04:03 PM

Could you explain what the " 3x4.3 over bore" is? I know the bore is the diameter of the cylinder and the "4 mill. stroke" you talking about 4 mill. longer than stock? Do you know how a multi-stage lock-up compares to the hays conversion?

n.c.rider · 09-03-2009, 08:27 AM

yes, its a 3mil overbore on pistons and a 4 mill bigger stroke on the crank. the tim hayes clutch is a work of art. it can be set up as a slider or a lock up. you can change back and forth by just moving the clutch springs around. if youre interested in dragracing you should check out the psychobike forrums. lots of info and some very fast bikes.

Mug_13 · 09-03-2009, 04:44 PM

Oh ok I get it..... You just put the two together by saying "3x4". Is the gain in HP of doing that more than what the turbo can add? Basically what im asking is if I left it stock size with a turbo vs. doing the 3x4.3 with a turbo. Which one would have the most HP? It seems that the thiner the cylinder walls are the less boost you would be able to use.

Not to sound rude but the nature of your questions leads me to believe that you are not ready for a seriously built turbo drag bike. If you don't know how to work on bikes then you're going to have to throw a ton of money at this project. A built turbo drag bike is not something that you just build and race. When you're at the track you have to be in the clutch in between every round. you have to have serious electronics and have a laptop to hook up in between rounds to adjust boost controllers, ignition and fuel adjustments, etc. The head will have to be coming off during the season for fresh valve jobs and inspections. This is just the tip of the iceberg. Are you going to be paying for all this work? A friend of mine has a turbo hayabusa that he uses to compete in the AMA. The work is just never done. He has over $100,000 into the bike.

Like I said, I'm not trying to sound rude. You might want to just think about a milder build. If you rebuild the engine as a straight up race engine you could have a bike that runs low 9's in the quarter and would be lots of fun. Just my opinion. My ZX12 has gone 10.0's in the quarter. I'd like to step it up to be a 9.50 bike. The local tracks by be run a 9.50 class that is super competitive with tons of bikes entered.

Keep on Drag Racin !!!!

The last AMA Dragbike event of the year is in Valdosta GA, in November. Don't know how close that is for you. I flew into Jacksonville and it was a short drive from there. If you can make it you can see what some serious turbo and nitrous drag bikes are all about.

Yea wont be able to be there...... Curently in Iraq. Got 5 months left, so I got a little bit of time to plan this out. I have got a little bit of money to put twards a turbo bike but no where close to $100,000.

Drag racing a zx10 is fun.....

How fast you go, depends on two things
-your riding ability
-your wallet

Determine how fast you desire to go, then reverse plan your components;
this will save you time and money

You can use what you have, lengthen your swingarm, add an air shifter, lower the ride height and change some gears. Looking at your times tells me that you are not a very good rider yet..... it won't take long to get better, with pratice

After you have some seat time under your belt, and understand what you are doing (learning what happens with the track, <60 ft, 330, 1/4, 1000, 1/4 mile times)

You can look at performance (exhaust, USB fuel management system, internal engine mods)

As you can see there is alot more to this then just throwing a leg over and saying I can do that.

You may want to hang out at www.psychobike.com; this is where all the drag racers hang

Sounds like you might have more money then sense. You don't need nitrous and a turbo. Turbo bikes are VERY VERY hard to ride fast at the track unless you put SERIOUS money into them. Why not just buy the bike, and stretch it and learn to ride it well. THEN put on a little nitrous, build the motor, etc....

AjZx6r · 02-13-2010, 07:47 PM

dude, im gonna sound like a dick.. well cause i am. but its in an effort to save you some hardship.

Get the 10. lower it, put n arm on it, ingnition module, power commander air shifter and LEARN TO RIDE, dont crack the cases, or add spray until u go 9.80 or faster with a bike set up like that.

n.c.rider · 02-20-2010, 06:53 AM

a stock motor 10 with an arm and a good rider should run low 9.20-9.30s. a great rider could probably put it into the 8s in the 1/4
