MPI mounting bracket problem

[tator]

anything flowing throughout the turbo housing at a lower temp than exhaust temp will cool, even the oil going through the bearings cools the turbo to some extent. just like the turbo housing will be cooler with a cold air intake vs a regular intake. the cold air will cool the housing. i can only think water running through the housing will drastically cool the turbo or greatly reduce the amount of heat transferred from the exhaust housing to the intake side. exhaust may be the same temp but i think heat sink effect would be less.

Your opinion is noted, doesn't change the fact our two turbos side by side the EVO is much much cooler. Although maybe something else makes the EVO so much more cooler but I doubt it

when you get both on the snow do you notice the evo running a higher water temp? or warming up faster when idling?

Evo runs at thermo temp, did not notice warm up time and really didn't check.

You guys are fooling yourself if you think that a water cooled turbo will make the under hood temps any cooler, the heat convection from the turbine side and the exhaust itself is where the vast majority of the heat comes from. The water cooling only runs thru the center section, not around the whole turbo housing and is basically only there to keep the oil around the bearing from coking when the motor is shut off and the oil stops circulating.

If you want to keep the heat down under the hood just install a turbo blanket around the turbine side and heat shield, wrap, or ceramic coat the exhaust.

I didn't notice any difference in underhood temps once the turbo was added just as long as you're moving. Now just sitting and idling is a different story so I try to avoid that.

Yes because additional cooling doesn't cool anything.....got it.

stingray we are wrong on the main reason for water cooled turbos. there is some effect to what we are thinking but the greatest benefit is cooling the bearing while running and after shutting down. looked it up. here at garret turbos website

For a guy that just installed two turbo kits you sure don't seem to understand the basics behind them... This conversation has absolutely nothing to do with the original topic so carry on.

Another broken bracket. Yamaha won't do #*$&@!

Mpi is coming through with a new bracket. Threads seem ok in the cover, hopefully I can get this fixed for good.

Shoulda Waited ( side winder )

 

[Byam]

Sideweinder will have different problem!
For this crapy cheap turbo kit, " installation is the problem" loooooool
They can go to hell, this bracket had a poor desing and it is wall mart cheap!

Your new one will do the same, and there is probably a lot of broken bracket on other sled!



Thanks god its over for me whit this GARBAGE Sled, and yamaha THANK YOU for letting us down ........

your positive out look is a big boost. but I feel you. way to much invested to ditch this sled.

did you put yours back together?

 

[Joe ltx-le]

MPI sent me the new bracket. They upgraded my waste gate for a good deal.
Hopefully I can line up the turbo better to the header, and it stays together. Sled works so good I'd hate to have this bracket break again.

Just my 2 cents (Canadian so 1 cent US)[/QUOTE]

LMFAO

Yes , and after that oil was always leaking from the mag cover at high speed .......
MPI gave it to me for free but...... 120$ us for shipping for a piece smaller than a i- phone if i knew i would have fix it by myself.............

Grab your exhaust by the tip and put pressure upright on it, the turbo mount move way to much! ( my opinion and many others to...)



The kit is for sale if somebody is interested, i also have a ECU redy to be ship for re- mapping

Update on my bracket install.

Mpi sent me my new turbo bracket with quick spoil waste gate.

During the reinstall of the mounts and aligning the turbo I had an issue with the turbo touching the motor slightly and also there was some strain being put on the mounts. Both problems stemmed from the alignment and I'm hoping they also caused my mount to break.

After many attempts in the tightening procedure I had to figure out another fix. The issue was the front bracket was not sitting just perfect, for whatever reason. Once this turbo is attached to the header and all the mounts are loose in place there is no "play". I've ended up getting a shim made to shim the mount to the turbo (1st pic). I know it's not ideal but it fits perfect now and there is very little strain on the mounts.

Mpi has been great help through this. They always call back. But you should note that they don't recommend just jumping into shimming parts of the turbo. But this is what I did ( get the point ?).

Maybe this can help someone else that lives to far from the states to send there turbos to mpi.

1st pic is my shim job.
2nd is the turbo and engine gap after shimming
