I Never resort to overkill! Never!

[Evadman]

For those of you that have not been following along, I am building a gocart. A fast one.

I haven't posted anything on it for about a month because of 2 things. The first (and major reason) is that I have been working too much and have not had a chance to work on it at all. The second, is that I was redesigning the braking system.

My original plan was to use one rotor from a Suzuki Sidekick on the rear axle as a driveline brake to stop the cart based on a few factors, the most prevalent being simplicity and the weight of the cart (hopefully <800lbs)

Well, I decided that one was not enough. If I am going to be doing 140+ in this cart, I want to stop, and stop now. (So I can outmanuver the cops of course 😛 ) And since the front of the vehicle does 70-80% of the work on braking, then I need brakes at all 4 corners. So I drew up plans for a new braking system.

The braking system will be based off of a Baha truck. (that's not overkill right?) Dual master brake cyl's with on-the-fly biasing front to rear, mounted reverse swing style to save space. The calipers will be Wilwood Dynalite II's with quad pistons, and will act on 10" diamter drilled rotors. (require a 14" wheel or larger) Fronts at .81 (vented), and rear at .38" thick. (solid). Bolt pattern on the wheel is 5 on 4.75, which 90% of GM uses, so parts will be inexpensive.

Of course, this is not just designed. I got the brake parts in the mail today 🙂 Now this is a caliper.

I'll take some pics of the chassis (which is done except for the suspension because I am waiting on the 1.25" chromoly tubing and .250 steel plate for the A-arms and spindles.)

Overkill is good 🙂

Woah. You rock. Please post pics!!!! 140mph? What motor? It doesn't sound like a go kart, it sounds like one of those...whaddaya call em? Outlaw things...w/the big wing on TOP ....they run on an oval dirttrack.

Man+machine+large amount of overkill = GOOD.

Sounds like suicide!!! 😀

Go-Karts f'in rocks!!!!!

You can see the progress over here. I will probably take some more pics of the chassis tommorow since it is all but done, and another of the booty I got in the mail today 🙂

The engine is a 1049cc 6 cyl 103 HP engine from a '81 CBX.

Holy crap. That thing'll stop so fast you better hope your dental fillings are in tight. I also want to know what you're putting in it for a motor.

Actually, it's fairly safe. The driver is surrounded by a chrome-moly steel tubing chassis. The driver wears a helmet, gloves and typically one of those fireproof suits since those motors run on methanol. The arenas have crash-barrier type walls, etc.

That's not to say you can't get hurt!!! But your chances of getting hurt are far LESS than the average street racer guy whipping his Civic/Mustang/Motorcycle down the street.

OH, OUTLAW CARTS is what I think they are called, right?

The engine is a 1049cc air cooled 6 cyl 103 HP engine from a '81 CBX. Now THAT is overkill 😛

The chassis I have built is made out of .095 1 1/2" daimeter tubing. I have a 5 point harness, but no firesuit yet. I do have a halon fire extinguisher tho 🙂

Wow, now THAT is different!!! You don't see those motors everyday. In fact, those are COLLECTORS' ITEMS! :Q

Why on earth are you using a collector's item that's worth MONEY as a possible sacrificial lamb? 😕

 

[waggy]

bwhahah. that is great!

heh hurry up and finish it. i wanna see pics! and make fun of you when you get in trouble with it! 🙂

My brother-in-law does stuff like this. Man we would get in trouble growing up (he started dateing my sister at the age of 15 i was 13) I'm amazed i lived through some of the crap we did. But man was it fun!

I have had the bike since I was in high school. In fact, I bought it from my high school. It has less than 4 miles on it. I am using it because: I have it already, It is a 6 cyl, and my brother wanted me too.

 

[Heisenberg]

So what will it weigh when it's done? I'm trying to get a ballpark for the power to weight ratio.

Is it possible to take out insurance policies on people not related to you?

Is it new or rebuilt? It has GOT TO be rebuilt. You have definitely got one special motor there. I mean...the CBX has been out of production for about 20 years now. 🙂

Hmm. 100HP motor. Total weight of kart+driver less than 1,000 pounds = freakin' fast!!! 😀

With me in it? About 750 lbs.

You wouldn't be the first one to suggest that. There was a pool going where I used to work on me living to 25. I should call up the keeper of the pool and see what my odds are. There are only 5 months left.

No, it's brand new. It was in storage at the school. It still has the 600 mile engine maintnence sticker on the front of the spedometer housing 😛

Looks like the brakes on our dragster we are building, our dragster is tad more expensive that your go cart though and it too uses chrome moly tubing.

Can I make a SERIOUS suggestion? For your benefit, consider using another motor and selling this one. You have a genuine collector's item on your hands and it's in IMMACULATE condition!! There's a CBX Owner's of America (or close to that) website out there. Email the webmaster...someone would pay you enough for that motor that you could buy THREE tricked-out 4-cylinder bike motors!!

Just look into it. I gain nothing from helping you.

CBX motors are rare. Low mileage examples are even rarer. 600-mile original motors with old stickers and shitt on them are like hen's teeth.

Sounds like sprint cars.

ok, doesn't it depend on the tires on how fast you can stop? If the wheel itself stops rotating, you will just slide, no?
