Default Help...just broke driveshaft on the dyno!!

I have a heads and cam car and today....on the third pull....the driveshaft gave way. It broke at the back, and bent my BMR torque arm a little.

My questions...is there any good way to fix the torque arm?

And what is a good driveshaft that will not break on me...and could handle a possible 75-150 (probably 75-100). If at all possible...I don't want to break the bank account, but want something strong.

How are steel driveshafts?

Any help would be greatly appreciated!!

So what shaft do you guys like.

I'm running a lingenfelter 3.5 inch. As I remember, Lingenfelter has put 700 hp throught them. I'm not sure how it handles the shock of drag racing, but it is a beefy unit.

dont see alot of broken steel ones cheaper too

i'll take some weight for strength anyday. Probably cheap too cause folks think they need to upgrade to aluminum to get that edge lol.

Is the Denny's Nitrous Ready piece the best/best for the money around?

I think that I may get this driveshaft.

Does anyone know what kind of wait that there is on the Denny's Nitrous Ready driveshaft??

I run the Denny's and seems to be a very strong piece.The U-joint's are huge on them.Handles my 3700lb car when I dead hook and pull the wheels a foot.
They should be able to get one to you quick this time of year.Just call and talk to Denny directly.He's a nice guy to deal with.

I'm running a custom 3.5" alum. shaft with 1350 u-joints. It's taken 40+ launches so far in the 1.6-1.7 60' range.

If I ever break it though, I'm going with the Nitrous Ready shaft.

Denny's Nitrous ready here too. Something else will break before that shaft does.
