Do a search in the forced induction forums, this type of thing has been covered many times. But you will find that on a 6cyl, a turbo is a far better option comapred with supercharging.

Re: supercharger on 4ltr el

Could you please explain why a turbo is a "far better option"? The most efficient of all forced induction is the SCREW TYPE (Eaton uses a ROOTS TYPE) supercharger- minimal input power and minimal air temperature rise. Not only that, they supply rougly constant boost throughout the engine speed range, unlike a turbo.
The only issue i see is with installation...and with an engine bay designed to fit a V8, i can't see it being too much of a problem.

Re: supercharger on 4ltr el

Yes screw type superchargers are efficient and would be a good option but it would require a fair bit of fabrication to hook one up to the 4L 6cyl. Turbo kits are fairly cheap, there are plenty of manifolds and parts around and they make excellent power on these engines. With most mid to large turbos, the big 4L will spool them up very quickly and you should see good boost at very low rpm. Thats why I would look at the turbo option!

Re: supercharger on 4ltr el

yeah its quite true a turbo will help achieve a greater peak power as well as a quicker et...its cheaper and i believe will work better than a supercharger which cost dearer... and wont give as much power....

Re: supercharger on 4ltr el

Different strokes for different folks.
People will argue all day about parasitic losses of superchargers and turbos being an exhaust restriction and the associated heat.
Obviously these aren't really problems based on the number of supercharged and turbocharged vehicles around the place.
I guess it just comes down to cost and which method you really like the best.
