supercharging a 400?
has anyone used a centrifugal supercharger on a 400? i was wondering what would be involved in this and possible cost. using 5-8 pounds of boost probably. im not very serious about doing this right now, but maybe if i get bored and have some money laying around...you never know.

Have you looked at Procharger?
ProCharger Self-contained Superchargers and Intercooled Supercharging Systems
They have a blow through setup that could be fitted onto a 400 with a 4 barrel carb. Unfortunatly they don't show any brackets for a 351C or 351M/400 motor. It would be worth a call or email.

i requested a catalog, just for reference. it would be nice to have 500hp or maybe a little more with the boost. theres no real good reason to, just to actually have it and see how many 350 guys will say they have about that too with their double hump heads and a thumpr cam or whatever they have BS about.

You dont need a supercharger to get a 500hp 400, i estimate with chi aluminium 2v heads and 10.6:1 my built will make 500hp at 6k and 500lbs of torque at 4500rpm with stump pùlling power from idle to 6k.... so instead of a supercharger why not some pair of heads like the chi2v or even a stroker 434 kit?

Maybe I'm wrong, but wouldn't a centrigual charger not give you the full benefits of that particular power adder? My point is, with the 400 being a fairly low RPM engine, and centrifugals producing more boost the higher the RPM's, it seems like you might not ever reach the chargers full output capacity, regardless of the pulley. Maybe if you ran a 8lb pulley, but still kept the RPM's under 4500, my theory is you'd probably be running more like you would if you had something like a 5lb pulley. Anyway, it's just my theory.
When I was looking at chargers for my Lincoln project, the Kenne Bell supercharger caught my attention as it achieves max boost at 1800 rpm, and stays so throughout the band. I'd figure with our engine characteristics, that's not a bad way to go if they had an application for it. I don't think they have one for our intakes, though.
The idea of a supercharger on a 400 is an interesting concept, though. Myself, I won't be doing it as between the CHI heads and the stroker kit, as well as the headers, carb, cam, etc, etc, etc., I figure I'll have more than enough grunt for my needs.

im not saying i plan on doing it, i was just interested in it and seeing if its been done. i see theres a stock 400 with a turbo on youtube. i just though supercharging may have been done before.

I think that a Turbo will run better on a 400 motor with lots of low RPM torque. The turbo will move the air at the High RPM area when a large cube motor can't get enough air. It's CFM that's required at high RPM, not 'boost'. If you can't feed enough air the boost will drop quickly.

JBradley500, i post a few month ago for a blower. BDS. Blower drive service have a blower for 400 for arround 4200 $. make a search for ( blower for 400 ) and visit Welcome to Black Diamond Software, Inc.

I think they were talking about blowers that would fit underhood. Those big ones like BDS, Weiand, and Dyer's are all tall enough to cause the need for cutting the hood, which is what it seemed they wanted to avoid. Typically the one's for that issue would be centrifugal, but I remember having seen a roots type blower that was mounted as an accessory low on the engine, and plumbed to the intake....but it also required a conversion to EFI.
