Is this set-up going to crack?? (pics) Thought I would post some pics to see what everyone is thinking about the way Im setting up my system. I dont want to use any flexable "links" till I get down by the trans. Im going to be running a brace off the frame (bumper brackets area), and using hump hose off my intake discharge hole to help support the weight. I am running poly engine mounts.
Im also wondering about adding a brace from the DP to the WG exit flange? Would this help keep things tighter, and less likely to crack?
OBTW - Everything is made from mild steel.
Thanks - Ron

My twin setup has solid motormount's and then the turbo's have a brace on them that go's to the front .That way the whole setup move's when the car flex's.The cold pipe's on mine have the coupler's and hump hose's as well.Just as long as when your engine or chasis move's your hot part's go with it,unless you have a flex hose in there somewhere.Hope this help's?
The only way you are going to be guaranteed that nothing cracks is if you use solid mounts at the turbos and for the motor. With the weight of the turbos being so far out they have stress on them.

The main problem is where the turbos are located...when you go to try and add some kind of support via the compressor when the motor torques and rests its going to put stress on them as well.
IMO, you have two choices:
Finish it and run it and see what happens
Go ahead and soild mount the motor as well as the turbos and just as long as everything is solid(frame rail to motor mount) it will be ok.
