From what I have read so far I like the idea of twin screw. Just cannot find much of this particular company especially on the 2006 platform.

 

Twin Screws are typically made by Eaton, Magnasun and Autorotor... Autorotor is what commercial airliners use to pressurize cabins.

 

You can find a Kenne Bell for the 4.0L... however I think with an inline 6 I would just do a well designed single turbo. Even with a brand new turbo and dyno tuning, I think you could get it done at about half the cost. I love twin screws, but I cannot build one as cheap as I can a turbo.

 

Why does this thread keep getting hijacked ?

 

I'm not looking for a turbo. I like the characteristics of a supercharger. Just trying to find info on the Sprintex version.

 

Call the guys at Road Race, as they told me they are the only vendors of Sprintex. Great customer service, as I used to use Road Race Engineering (sister company) for my boosted M3's needs... Even if they dont OFFER a kit for your LJ they would be east to work with to acheive a "builder" setup. All you need is a belt to drive the SC, and like anything else the intake/discharge can just be plumbed in.

There it is!

 

Hmmmm.....what you are dissing here, seems to work for saleen, chevrolet, ford, and others....just saying.

My friends saleen mustang has the S/C mounted right on the intake of the block....works fine...sprintex is no different...monitors the air before the supercharger as you cannot get at it otherwise.


the twin screw is much better for streetable/off road style driving....the centrifugal is more geard towards hi rpm race applications...thats breaking it down really simple...im using my experience of having a LS/VTEC motor with a jackson racing supercharger attached and my friend having a GSR integra with a vortec blower. My car with a JR would beat the vortec system for the first 1000ft. then his vortec would get on full snort and come back beside me. nature of how the systems work. twin screws make lovely low end grunt and cent. blowers make their power higher in the rpm range when they get some RPM in the blower itself.

Neither is bad, just different...I know that I want low end grunt and could care less about having a rpm burner!

 

You need to recheck that, most, though not all, DO remount the IAT sensor after the compressor. It is optimum for the best fuel and timing corrections. That is all that was stated.
