i see him hunting down the 2js? if the motor is built maybe?

 

You mean 2jz?

If so, a centrifugal SC and small turbo is not going to make near the power to hunt down a built 2jz motor

 

^^^
I think 2js was the plural form of 2jz,

as in many 2jz's, or all of the 2jz powered S2000s.

:End english lesson:

 

2j's does not equal plural form of 2JZ, it's being lazy and not taking the time to spell 2JZ's.

 

Unless it's a really small quick spooling turbo I'm not sure I see the point. Maybe a GT25/28?

I'm running a GT3071R and it is spooled by 3500 and makes well over 400hp up top.

As for those saying the SC is being over spun by the turbo..... oh please. A centrifugal compressor is not designed to be driven by air through it's inlet so it will have very little effect no matter how much air the turbo is pumping.

 

I is good at engrish!

 

They are in the same city! They are both Bama owners.

 

I agree. I can see the logic in coupling a small roots or screw type positive displacement supercharger with a large turbocharger. The supercharger can be spun very quickly at lower RPM and then be either disengaged via a clutch or bypassed and allowed to "free-wheel" at higher RPM. After the supercharger is bypassed, the engine would flow enough air to have the turbo spooled. Best of both worlds, really.

This setup seams a little pointless to me. If a large turbo was used, then both compressors would only function well at higher engine speeds. If a medium sized turbo was used, there would still be little to no positive charge at low engine speeds. To gain low RPM boost, a very small turbo would be in order, with a very small turbine. The small turbine would limit air flow at higher engine speeds, hindering the whole setup unless an efficient turbine bypass was also implemented.

The whole thing has me asking "why?". A 2JZ S2000 even makes more sense to me

 

Wow! That is one crazy set-up.

 

i dont understand why s/c is needed for downlow wit a turbo spooling by 3500, i could see the need if it spooled by like 5-6k
