Speaking of turbo bracing...
 

I know it has been mentioned, but its hard to keep going back into random threads and finding certain pages for this subject... so I was wondering, what did you guys do to brace your downpipe and turbo? My hoopdy brace sucks ass, and wasnt well thought out. It holds, but it doesnt take alot of weight away. I put my setup on a "specialized" tensile scale that my buddy's rollcage shop had, and my manifold was still supporting just over %50 of the weight... no bueno.

I have a BEGi S4 style manifold, that has been rewelded to shit and before I purchase a better thicker version from ETD, I was thinking of welding up something like this:

this style that bolts to the engine mounts from BEGi:

Or this style from FM, which looks like its made from autozone stuff.:

I dont want to spend alot of money for premade shit, I rather make my own for cheap.

What is this?

I saw something similar at the BMW museum in Munich a few years ago and someone told me it was a water pump.

What is the name of that orange hose?


All the racecars I know of only brace the turbo on the CHRA/turbine flange metal tab thingies with a crane. I still want to build one for mine but time and money are getting in the way.

anything i think from fm is good stuff

Renault calls this-

"sèche-cheveux qui se trouve en dessous du tube orange"

More importantly, why can I see the back of the cam gear?

Why shouldnt you?

Orange tube looks like boost reference line to the wastegate with firesleeve to protect it from heat.

what is the term for the opposite for "supercharger"?

it's either a belt driven exhaust compressor

or an exhaust driven supercharger??

edit: we're dumb, it's probably a water pump. looks to be bolted to the side of the engine.

I'd guess some crazy water pump. The device its attached to appears to be a dry sump oil pump..

:bowrofl: Ok, that's just damn clever.

Yeah, at the front that's clearly a multistage dry-sump pump, with a shaft coming out the back of it to power the hair drier. I think Hustler et al must be correct- gotta be a water pump.


Pen2, Is that an old F1 engine?

yup its a renault F1 Turbo, I have seen it a couple of times, but I just recently come to discover the crane brace... since I am looking for bracing options I just now notice things.

I'm going with water pump. I haven't seen one of the Renault engines in person to be sure but it's a very similar layout to a Cosworth DFV F1 engine.

Maybe its spinning the opposite direction that were imagining and its actually a vacuum pump for the crank case.

hmmmmm?

Since this thread was already started about turbo bracing, I'll ask my question. If a car has nearly solid motor mounts (hockey pucks and threaded rod), how bad an idea would it be to brace the turbo to the chasis. I haven't driven the car with the new mounts yet, but the engine doesn't want to move with a long pry bar trying to move the engine. It could be the stupidist idea ever, but with the way I built my manifold, it would be much easier if it would work.

I was wondering this too, like what if there were separate motor mounts used instead of a solid bolt? Or a Heim joint?

The brace included with the Begi S4 kit is a heim joint that bolts to a motor mount bolt (the motor side), then runs to the hotside discharge flange. 2 years and 30k miles and mine is hold up well.

Oil pump.

I'm fairly certian the dry-sump header tank pumps are not a seperate pump assembly, pumping through the block. Its more likely that the oil header tank is electrical.

TB on turbo inlet as well?

yes, something Ive always wanted to do. For one, it eliminates the need for a BOV, butr in addition to that, it puts the compressor wheel in vacuum while the throttle is closed which helps keep the turbo spinning.
Kinda like when you put you hand (or w/e :giggle:) over the intake of a vacuum cleaner, and you hear the motor increase in RPM.
