Notice the small size of turbos?
To avoid surge the twins must be small, however, you can use a smaller turbo on your motor then go with another turbo about twice the size for a compound setup. This will yield higher boost levels at low boost setting and at much cooler charge temps with charge cooler (IC) it would rock......

Has anyone ever messed with a paxton huffer on a 6.2/6.5
The old Studebakers howled with them. I know that a belt driven supercharger is available for many applications????????????????

Some of the H1 Hummers with 6.5's have installed superchargers. Have viewed a few web pages about those conversions.

who if anyone makes a supercharger or "blower" for the 6.2/6.5

MARINEDIESELUSA.COM has a supercharged 6.5 package.
There are a couple of threads on the page about it. Someone put a 300HP in a dually. I think they are in the archives but a search will pull them up.
I think Eaton use to market a supercharger 3+ yrs ago but lost the link a long time ago and never saw anything about the intake or mounting.
Seen pictures of a few twin turbos on the web and they are all custom fabrications. Hats off to anyone who can fit it under the hood.
Haven't seen anything new or recent on twins. Last interesting thing was RJ's modified single turbo. A documented improvement. Heard of other guys doing holset turbo swaps but nothing really documented as an improvement.

The superchargers I recall seeing were one of a kind installations. Do not know af any "kits". Paxton, and a few other make the newer style superchargers (vs the old 6-71 blowers). They are typically belt driven off the front of the engine. Fabrication of brackets, and air tubing is the major work involved. Gives better low end power that the turbos, but takes engine power to operate. Less efficient than a turbo, but in an H1 one typically is not to worried about efficiency. Superchargers cost even more than a turbocharger, so most of us 6.2/6.5 truck owners consider the turbo a better deal because of lower price, kit availability and efficiency.
