Bully basket. Steel vs aluminum?

I am looking for a steel basket now . Wanted to try the steel to see how it holds up compared to the aluminum. Don't think performance wise I will be giving up any at all. Just my 2 cents worth.
 
Well begging your pardon,just how ruff do you think a jr 1 will be on hub,you people are amazing,Braxton all things being equal it is not cost effective,nor a benefit.

Thanks for the reply. My son's bully has a steel basket. I'm currently getting his kart ready for spring. It has a 2 disk bully with a steel basket and I am sending to get rebuilt. I just wanted to know opinions because if it needed the aluminum basket now would be time to do it. Thanks
 
Keep the steel basket, it will last much longer. No need to waste money on things you dont need
 
if you have it run it

What will make a difference in performance on the track is when the engagement tabs on the plates wear notches in the aluminum drum and it starts hanging up at bad times. Been there once, never again. If it doesn't have steel reinforcement inserts (had one like that too; it was ok from a wear standpoint), the drum gets replaced with steel. Will it make any difference in performance? Nothing you could read on a dyno with any instrumentation affordable by a normal speed shop.
 
I'm glad we amaze some people. Evidently their Jr. motors aren't making enough power to damage an aluminum basket.

We ran the Gold Cup series in Jr. 1 and Jr.2 and after a few races, the tangs on the disc were wearing the aluminum basket. Replaced them with a steel one and no problems.
 
I liken this discussion to the heavy versus light flywheel debate. (which is why I posed the question in my previous post "Do you really want lighter for a jr 1?")

Big exception being that the diameter of the clutch is minimal compared to the diameter of the flywheel,
and the difference in weight between the aluminum basket and steel basket is negligible.

What's most important is as Harry said -- that the tangs do not hang up on the basket. That surface needs to be flat so that the friction discs can engage smoothly.

I'm with Martinbuilt on this one.
For durability: steel basket every time.
Some customers prefer the aluminum basket. That's fine...We build them both ways.

Glad we "amazed" or "amused" at least one person. ;)

Today's modern PLC 's are very affordable - also known as"bricks". They range from $120 - $400 depending on brand and I/O. Using this technology, you can add a clutch dyno feature to your inertia dyno that will see a difference. HMI, software and knowledge not included in the above prices. A nice package however can be obtained for ~ $800.
