I was thinking about the bracket this morning. The bracket is not going to provide much vertical support. It's a cantilever beam with a single mount point to the engine. What it will support/resist is the horizontal movement.

With everything bolted up, the turbo doesn't move around....so I just don't know important it is.

on a lot of turbo cars, leaving out a support bracket will cause you issues in the future. cracked headers, stripped header/manifold to head studs. The turbo is a lot of weight, whatever amount of support that bracket provides, it's worth it.

I looked at the bracket this evening. I did not know it had the lower vertical brace/mount. With that it will provide adequate vertical support. So I withdrawl my comments that the bracket won't provide much vertical support.

I'll probably try to install the bracket.

I don't even exactly know what bracket we are talking about, but I would vote for it because of some of the bending, breaking parts I have experienced with my supercharger.

While parts may feel secure and strong, everytime you turn, give it gas, brake, and so forth, that heavy piece of metal that is hanging there, gets to strain all its existing bracketry and so forth.

My supercharger mounting plate has started to crack, the sheet metal where I mount a mounting bolt has almost completly sheared through, and a bracket that I cant move very easily at all, moves by itself when you rev the engine.

Josh,
I see your point, the engine is secure with the tranny and the up pipe is secure with the engine and the downpipe is secure with the tranny. If its going to move it will do so as a whole. I guess its just a small level of added security.

I'm debating putting a flex joint in the uppipe I build to combat gasket issues I've heard about with stainless steel. Cast iron is best but its not something a guy can build in an afternoon.

I added the bracket when i pulled the motor today. It's definitely a lot more sturdy when the turbo isn't hooked up to the down pipe.

I did notice that there was a little gap initially between the up pipe and bracket. Snugging the nuts down closed everything up.

yeah, I'm not sure if it was my gt-spec uppipe that was a little short or my vf34 was too big and needed to be raised or a combination of both. but if you look at my pics I had to make a 10mm thick bracket to sit the turbo on. good to see someone with some free time to work on their car though, I'm very jealous
