[I like karts]

Holy crap!!

How hard were you pushing that thing?!?!?!
You broke like everything there is to be broken!

That sucks cuz they're so expensive

[ironman]

**** i will never again get upset when i think i spent to much in a day after seeing all the damage you did and the money lost. sorry for your lost.

[Kenny_McCormic]

Is the case OK? What the hell made it blow?

[risto]

i couldn't do that much damage if i tried!

*moment of silence for your loss*

[jr dragster Tyler]

Well...When 8000 rpm's go wrong it REALY goes wrong and when one thing breaks it's a chain reaction. and no the block is pretty beat up when the rod end broke and go sling shoted arouned the engine block at 8000 rpm. And what causes them to break is just fatigue. It was not my fault what-so-ever because There's no way to blow these up on purpose because we dont use a maunual tranmission (cant go into an over-rev) PS 8000 RPM is normall for these. And for you guys who want to upgrade your bashing/karting engine you can run a stock briggs crank at 7000-8000 rpm. We broke a stroker crank which cost 450 to repair. Where running a stock one which quite a few people run. But the car will be slower with the stock crankshaft because the old stroker was billet steel the stock crank is cast steel

[oscaryu1]

You mean overdrive...

8,000 only? Fatigue? I've heard Clones being run harder than that... Sorry for you loss man...

You could try DEstroking it for better top end?

And what's wrong with the cam? It looks... allright..?

[ed1380]

dang thats a bit whalop right there. costs more than the whole engine of my car. (thrown rod too)

@ oscary-the cam is bent from where the rod hit it

[kibble]

Two words: DANG!

Ah yes now I can see. My laptop wasn't displaying that picture, but my desktop is.

DANG!

[rockstomper]

Was this the nice looking engine you had in one of your posts??

[crazycart]

In the 1st pic that gear reminds me of the transmission gears that i destroyed in my trike hahaha

I doubt you had insurance on something like that? lol

[Magice]

I'm just waiting for russ to chime in :P

[Russ2251]

I'm just waiting for russ to chime inI did, but was deleted for reasons unknown.

[jr dragster Tyler]

uhh you have heard of a clone being run harder than 8000 rpm? trust me when that engine starts up you feel it in your chest and in your feet. And at 8000 rpm the thing is just screaming.

[jr dragster Tyler]

and yeah that was the nice looking engine I had with all the blue anodized part's

[oscaryu1]

Dang man... so did you find the root cause?

Haha I personally would do 8,000 when I'm wanting to commit suicide haha! The block literally blows itself off.

[risto]

the highest RPMs on a clone i've ever seen/heard of is a Harbor Freight running 6400 RPMs...and thats with about a grand worth of hop up-Honda parts.

My favorite post on here:

Really? Haha a GRAND? I've spent about that much... and I'm pretty sure I can hit lots higher.

If he spend 1G on it, I'm betting he has a ARC flywheel. Those have been tested up to 12,000RPM or such. I'm guessing he's running the stock carb then...

[kibble]

I did, but was deleted for reasons unknown.

Really? I don't see any remnants of anything that says it's been deleted? :confused:

[Russ2251]

Yup, I even checked it after posting. Next day (this morning) wasn't there. I believe I was first poster.

[kibble]

OH! I know why, because it was on a different thread, the one that Jr requested to be deleted.

[robertdjung]

Sorry Russ!

[Russ2251]

Stuff happens.:thumbsup:

[jr dragster Tyler]

For everyone asking about the root cause there isnt realy one. Im not quite sure if some of you guys know what a 4 stroke high compresion alcohol motor at 8000 rpm sounds like. It sounds like godzilla taking a temper tantrum. So parts wear out and get tired of doing 8000 rpm every weekend and alcohol breaks down parts quicker. But the motor should of lasted longer than half a year.

[redcali]

alcohol breaks down parts quicker.

does it actually?
it should run cleaner and smoother and be far better for your engine?
like nitrous oxide is almost good in small amounts to clean your injectors in a normal car

[gocartkid]

....It sounds like godzilla taking a temper tantrum.

He is right....and sometimes :censored: just happens for no reason. Sorry to hear about the destruction, but hey, now you have a cool story to tell and some awesome paper weights for your desk!

[jr dragster Tyler]

Haha yeah its all paper weights. Cant expect these things to last forever. and the long term affects of alcohol is so strong that it can start to cause erosion in our aluminum carb boals.

[jr dragster Tyler]

Ok well a brand new 3 1/4 RHINO race engine and a brand new halfscale junior dragster is on its way!!:2guns: :cheers2: :arf: :drool5:http://www.skeeters-law.com/0_3.5_engine.JPG Thats simmilar to what it looks like. And if you dont know what a 3 1/4 bore engine looks like or sounds like Its the BIGGEST Most bad A%$ motor you will EVER hear in your life. It has a 42 mm mikuni carb and a 2 inch exaust pipe. These engines are all billet. Just the Rhino blocks for these things are 1800 bucks. Online a complete Rhino 3 1/4 engine is anywhere from 4000-5000 but we are getting it for 2800. And I wish you could all hear this run in person, you can feel the thumping in your chest. But I guess a video is the best I can do. Ohh and about time and speed in the 1/8 mile this motor is capable of around 7.20's at 95 MPH But we have to slow down to 7.90 @ 85 mph:mad2: :roflol:

[oscaryu1]

Completely billet? 42mm Mikuni? 2" Exhaust? That's just... ****!

[kibble]

That's a nasty looking engine, and by nasty, I mean awesome! :thumbsup:

[jr dragster Tyler]

Yes COMPLETLY billet aluminum block. and 42 MM MIKUNI carb on alcohol. These engines sound very nasty!!! And you will see my new car and engine in about 2 weeks. I also got some new racing gear to be in SPEC. We bought a simpson bandit helmet, gloves, jacket, and new wrist restraints. The link is for the helmet.

[ed1380]

IDk about no billet or mikuni, but do you have any numbers on those engines? hp? torque?

[gocartkid]

That thing is so bada**!!! :2guns:

[jr dragster Tyler]

IDk about no billet or mikuni, but do you have any numbers on those engines? hp? torque?

Are you trying to tell me it doesnt have a mikuni 42 or completly billet? it makes around 70 HP. Not 100% sure but its guestemated around there. I dont need numbers to tell me. The thing can run 7.20's in the 1/8 mile @ 95 MPH. Try to do that with a briggs 5 or a clone! I may be only 14 but I darn sure know my stuff. Its EVERYTIHNG in the engine including the block is billet aluminum. or a couple billet steel parts like crank shafts.

[ed1380]

i was saying i dont know/care what its made of. i just wanted numbers. and **** 70 from a single cylinder. :drool5:

[jr dragster Tyler]

Yeah its pretty insane. Who needs 2 or 3 cylinders when you can have one huge one?

[crazycart]

Who needs 2 or 3 cylinders when you can have one huge one?

Lol people who cant afford to replace the topend every few races(like me,but i couldnt even afford that engine in the first place :roflol: )

BTW that thing is Badass.

[oscaryu1]

5HP Briggs or Clone create 70HP? In your DREAM! That engine was built from scratch for hardcore racing. The Briggs were made for longetivity... Clones were made for multipurpose use...

[jr dragster Tyler]

Lol No I never said that a briggs 5 or a clone can make 70 HP. I was saying to the other guy that if you dont belive me that the engine makes around 70 HP and all billet and can run 7.30's @90 MPH

[ed1380]

so im just another guy :toetap05: :arf:

[jr dragster Tyler]

Update: My dad surprised me today and said that hes ordering the Half Scale outlaw junior dragster with beadlock rims. The bead locks where only 175 bucks for 2 rims!

[Kenny_McCormic]

Beadlock meaning? Like the tire is locked to the bead? I have seen this on full size drag cars of all sorts but done by driving self drilling self tapping sheet metal screws into the rims and though the tires.

[rockstomper]

These are the bead locks I will be using on my next project!!

No no real beadlocks with the ring.http://atv.off-road.com/atv/data/articlestandard/atv/442005/191589/misc%20232_300.jpg click link for a example.

[oscaryu1]

Nice! What's so good about them?

[Kenny_McCormic]

The tires cant spin on the rims. I was figuring something more professional than screws, just how I have seen it done dirt cheap.

[2or3wheels]

These are the bead locks I will be using on my next project!!

Rockstomper

so u mud?

[jr dragster Tyler]

Whats so good about them is that they look nice for one and for 2 My dad was just talking to our engine builder and he suspects a ET in the 1/8 of 7.30@90-100 MPH so My dad wanted bead locks for safety

[oscaryu1]

Ah... my safety is a $30 helmet :D

If I flip over... my head will be the first to crumple...

Anywho, they look SWEET!

[jr dragster Tyler]

haha about the helmet. Thats all I wear on my go kart. But when it comes to racing well...you know...lol

[oscaryu1]

Haha I can imagine you:

"Spartan Tyler" :D

Oh you have a go kart too? Post it up! :D

[jr dragster Tyler]

Yeah you havent seen my kart Not a race kart. my off road one

[oscaryu1]

Dune buggy? Post it up! Cmon :D

[risto]

you holdin' out on us?
