Tyson Posted May 22, 2011 Share Posted May 22, 2011 Toyota wouldn't have put it there unless it needed it. My advice is get a brace fabricated with a curve in it so it clears your new exhaust position. Quote Link to comment Share on other sites More sharing options...

Structural bracing I think is a lot more important than lowering the cars emissions.... Quote Link to comment Share on other sites More sharing options...
d_d Posted May 22, 2011 Share Posted May 22, 2011 Id say this bracket was incase the prop failed, to stop it hitting the ground flipping the car, thats my thoughts on it anyway. If it was me id leave it in place. Quote Link to comment Share on other sites More sharing options...

If it was me id leave it in place. Agreed. If the prop went without that bracket there it would drop and the car could flip. With it in place it will just rattle around a bit.

Lude Posted May 22, 2011 Author Share Posted May 22, 2011 right. if thats the case i will remove it, fit the exhaust nice & high, then modify the brace to fit around the exhasut... Quote Link to comment Share on other sites More sharing options...
bobapple Posted May 22, 2011 Share Posted May 22, 2011 Mr T did think of everything didn't they. The only thing is that is at the back of the car isn't it ? so surely he would need it to fail in reverse to flip the car wouldn't he ? I personally would leave it or as suggested earlier get one fabricated. Safety features are always a good thing. Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted May 22, 2011 Share Posted May 22, 2011 Agreed. If the prop went without that bracket there it would drop and the car could flip. With it in place it will just rattle around a bit. But its at the back of the car, just in front of the diff? Cant see it doing much good there. Its only thin gauge metal as well so cant see it bracing much Quote Link to comment Share on other sites More sharing options...

It doesn't need to be heavy to stop the prop from falling to the ground, it would only need to be able to hold the weight of the prop..... to stop it from dropping, by which time the angle between the gearbox and the end of the prop would cause serious problems.

Swampy442 Posted May 22, 2011 Share Posted May 22, 2011 It is where it goes, what Im saying is if the prop broke anywhere except right at the diff flange that would be useless as a 'prop catcher' Quote Link to comment Share on other sites More sharing options...
skippyboyo1 Posted May 22, 2011 Share Posted May 22, 2011 yes mate 100% leave it on or make something that does the same job but gives you the room Quote Link to comment Share on other sites More sharing options...
Scott Posted May 22, 2011 Share Posted May 22, 2011 It is where it goes, what Im saying is if the prop broke anywhere except right at the diff flange that would be useless as a 'prop catcher' I don't understand what you mean? If you have one at either end it will always be caught. If it breaks in the middle, both will stop each broken end from hitting the ground. If it breaks at one end, pre-bracket, then the opposite end will catch it. If it breaks at one end, post-bracket, that ends bracket will catch it.

Stephendjb Posted May 22, 2011 Share Posted May 22, 2011 (edited) I don't understand what you mean? If you have one at either end it will always be caught.

If it breaks at one end, post-bracket, that ends bracket will catch it. Depends how close it is to the UJ that back one looks very close from that pic I'm sure the front one is much further away and would do the job as you describe it. Edit. Scratch that there's no rear UJ on a supra & the donut doesn't allow enough movement for it hit the floor (at least not with the weight of only half a propshaft) should the centre UJ break so Craig's scenario doesn't matter.

Swampy442 Posted May 22, 2011 Share Posted May 22, 2011 What about the centre bearing? If it broke in the middle of the section after the bearing but before the diff, all the prop would do is flail about, theres no UJ in that section and that brace would do nothing.

Not sure, maybe it's designed in such a fashion that it is structurally less sound in certain areas in order that should it fail it's in a controlled area?

Stephendjb Posted May 22, 2011 Share Posted May 22, 2011 Have you tried pulling the prop down Craig? There's very little give in the donut so the centre breaking would hardly affect it it at all as there's very little weight or leverage from half a prop.

Chris Wilson Posted May 22, 2011 Share Posted May 22, 2011 It is a prop shaft safety loop, no way would that bit of tin, positioned there, make any real structural difference. it contains the flailing rear end of the prop, if the doughnut fails, and being restrained it hopefully can't flail enough to come through the floor pan, which is never a good thing. If you feel OK about the slight risk you can remove it. I see loads of MKIV's without them due to ill conceived and fitting exhausts.

2soops Posted May 22, 2011 Share Posted May 22, 2011 My Mk3 had one exactly the same and when i routed the twin 2.5 exhaust for the chevy engine i removed it with no noticable structural problems. I think its more of a brace than a prop catcher as previously said its way too far back to be of any use. If the rear of the prop broke it would simply drop to the ground causing no real problems anyway. Personally i would remake a different shape one to suit the exhasut just to be one the safe side.
