Torque bar snapped!

[SilverBullet]

It finally happened! One of the bar snapped at the area where bar meets the screw on head, the bar connecting the trans fork to the top of the shock mount. Now I've got to drive slower as I've got monoball spring plates and no torsion bar. I'll get the welder to make a similar bar but maybe out of iron!

Which bar/brace are you using? CSP? First I've heard of one snapping...

[SilverBullet]

Yes the CSP's torque bar! My mechanic told me when installing that it wouldn't be that strong plus not using torsion bar, the bars especially the ones from the horn to top shock mount will be under alot of stress and also taking the bulk of the cars weight. I'll try to take some pictures of it and post it.

Sad, but also very cool that your engine has such a power that it would break a torque bar!!

What engine did this?

Thanks for sharing

Wally, I dont think its my engine which snapped the bar, but most likely my style of driving. I enter and exit coners at high speed till the tyres start screeming. I guess that plus very hard setting of the rear dampers could be also facts contributing to the failure!
Btw its a small engine 88x69 w110 44 heads stock carb, bas exhaust. .
But animal is being chained till next month. T4 103x80 schl.340 48x40, 48idfs,remmele's exhaust.

Now, you are talking

OTOH, its still very weird that the bar snapped. The load is supposedly along the axis of the bar. Breaking it that way is very very difficult. I would suspect a less than ideal installation.
Way more powerfull cars with way harder suspension have used these bars with drag race starts many times over without failure, so it is hard to believe its a design fault...
Welding the taps straigth towards the direction to which the bar attaches to is critical to avoid lateral stresses. The bar is not designed to take lateral forces.

Anyway, please, do show pics and specs of your future engine Sounds spectaculair!

Thanks,
