I was in Muskegon, Mi. today so I stopped by and checked out www.bullseyepower.com today.
Very impressive, I never saw so many turbos in one place before. They have the foundry and machining facilities right there too. Thousands of turbos on the shelf. From diesel turbos to small car replacement turbos to race car stuff.
In talking to the owner, Dave, a comparison of turbo sizes came up and I have changed my mind on what I want to be running.
Next on my list are a couple Borg Warner S475 turbos.
They are on the shelf there, polished compressors and all.
Some food for thought,
Gale Banks system Rajay turbos, 56 mm compressor inducer, T4 turbine housing flange
Garrett TV77 turbos I have been running, 65 mm compressor inducer, T6 flange.
Borg Warner S475 turbos, 75 mm compressor inducer, T6 flange.
So guess which one is going to have the most HP capacity and the least back pressure ?
My spool up time with bigger turbos is going to increase by 1/2 to 3/4 second or so and I can live with that. With the Garrett's my spool up time is 17#/sec. and lag is not even noticeable.
