A dumb question maybe...

[koldsimer]

Someone tell me how top fuel dragsters have wheels with what appear to be five large but normal size lug nuts and studs? I never recall seeing them break really, so what's the secret?

With such the large pattern it spreads the load over the whole center of the wheel.

Another cool fact is that monster trucks dont have cooling systems.

Makes, since... that just seems like a sheet ton of torque going through five studs. Please school me on the monster trucks. No cooling system?

Nope no cooling system, raditor etc.

I was talking to one of the guys that owns a team at the 4 wheel jamboree and he said that not alot of them use cooling systems since they are only out there for a few minutes and that they rarely ever get hot to where it will damage the motor.
I was pretty shocked to hear that.

Wow. I almost don't believe it but, yet again, what you say makes sense. A motor will have a certain time running/temparature relationship and i'm sure those guys know their motors pretty well.

The motors are also run on alcohol which burns alot cooler just like in dragsters (which also have no radiators), that combined with the fact that there only out for a few minutes means they dont heat up enough to justify the weight and compexity of a cooling system.

yep he also mentioned that they are always pulling the motor for work so they hate messing with coolant getting everywhere.

That seems to be moe of a trivial reason though...A nice benefit though!

They're not really normal-size. They're like 5/8" IIRC.

I would have thought that they would need to be at least that size. Still trips me out that 5 do the job.
