I really liked the powerband of a centrifugal as well for my needs.

The heatsoak from a manifold mounted supercharger was one thing I didn't like. I guess with the reliability if you change the oil every 6000 miles then I wouldn't think the procharger would have much of a reliability problem. I just don't like the idea of a roots pushing all its boost in my engine when I'm cruising at 60 mph at 1400 rpm. That to me is unnecessary wear and tear imho If I'm wrong about either please someone correct me. I'm not above learning anything new.

I believe roots is more reliable. I mean I don't think any auto manufacturer has used a centrifugal supercharger since the 50's-60's. Also aftermarket boosted vehicles live a tough life, and generally the only ones I see with 100k plus miles of boost are roots. Why that is, not sure.

Love coming home from a long work trip to some fresh new mods on the Pavement Princess!

TVS2300 is on and she is leveled out with a SuspensionMaxx kit. Now I just gotta remove some tread to warrant new tires....

 

Keep us posted on this... great addition!

i dont think a roots blower would be forcing max boost at 1400rpm. Your crank turns the blower so its output is based on Engine RPM and the pulley. When you are not feeding more fuel, the supercharger wont provide more air until you put your foot into it. A good electronic boost controler and wastegate setup will help you, but realisticly at a maintained cruising rpm your charger should be making Like 1-2 PSI right? Maybe im wrong about that but to me a supercharger should only make boost when you want it to. My old duramax cruises at 3-4psi on the turbo and spikes to high 20's when you get after it. My Cat can make 61psi manifold pressure ;)

Roots style blowers are positive displacement blowers, and make their boost from idle on. Thats why they are so popular in street builds. The downside is the boost levels out at around 3k rpms so they kinda feel flat in the upper rpm levels. You're duramax like mine makes its boost relative to throttle input from the exhaust gases. A centrifugal supercharger works in the same way as a turbo in that the throttle increases the boost. The joke for a long time has been that a procharger is basically a belt driven turbocharger but without the lag. They are both great systems, and with the new 8 speed transmission getting into the boost with a procharger can happen really quickly when you wanna get on it. Under 3000k rpms you're running at stock power levels.

My 92 has a whipple for 25 years and 112K miles. Sometimes I run 5lbs of boost sometimes 10. At speed it doesn't pull boost to speak of. And the oil is self contained with a life of 100K miles. The vortec I've run-uses oil the engine used. I prefer the whipple.

In reality the whipple, tvs2300, and the procharger are all great units. It depends on what you want out of it, and I'm thankful we have the great options we do.
