My BW S475 project... lots of pics.
So.. i finally sold my greddy t78 kit and went for a borg warner s475 with 1.10 A/R.
Car summer 2008
[youtube]http://www.youtube.com/v/uslGUyz3a5A&hl=sv&fs=1[/youtube]
2007/2008 winter build up with new fuel system, weldon 2035 pump and 6x1680cc injectors
2007/2008 i also installed the t78 turbo kit and made a new manifold.
The car was dynoed a couple of times in 2008 and at 21psi it made 548RWHP on E85 tuned by myself.
As usual that was fun for a few weeks and now winter has arrived and my fingers itches like hell!
Two weeks ago i received some material to work with, i've been welding some aluminum but never done anything useful with stainless..
First off, i did this to be able to make....
this fixture of the new manifold.

finally...
THe new turbo on the new manifold, the fixture did its job, it is tight but it fits
now the wastegates, 2 synapse 40mm wastegates.
First wastegate there..
Space was a big issue here, it was hard to make room for both of them, i probably got the manifold on and off the car 30 times before i got it right.

Nice job and fast as usual Gustav "thumbs up"! So you kept it 3" the last way? Must try to locate a good air filter for you or as we speaked about a cold air boxed system maybe is the way to go? Now to a question to all you BW 475 lovers, what kind of hp at 20 psi boost and at what rpm is Gustav gonna make? This would be on a RotoTest hub dyno. Myself i think 600 rwhp@7700 rpm@20psi!??

600 is alittle high for only 20 psi esp since this turbo doesnt start moving until 20+psi.. prob 525 is a better number at 20psi. you have to run big boost with this turbo to make power.

The intercooler piping from the compressor outlet has too many bends IMO. I would have opted to a larger single wastegate and put it as close to the turbine inlet as possible... You're on the right track, we all just do it differently. Beautiful port matching on the Excessive LIM (I bet you hated how bad they come cast too...) Also, Excellent work on the manifold!

Thanks for nice comments,
I dont want to speculate about power, time will tell, will put the car on the dyno when im finished.
With the greddy turbo the car put down 499whp @ 17psi pump gas, 506whp@15psi E85, 548whp@21psi E85.
The goal with the car is to run a 10 on 1/4 next summer
the LIFT is my best tool
