Another one of those "How Big" questions

Post by ian.stewart »

I was in the right place right time situation the other day and picked up a Paxton Blower for the princly sum of £15 :D
Its rated at 440cfm @60000rpm, which I assume is the input shaft driven speed,
what I dont know is if its big enough for a 4.6, or shal I save it for my sons 2.4 pinto

I dont know how you do it, its scrap value must be more that that.

So now the real fun begins.

Acording to my book by Mr Allard that should give you about 5psi at 5000 revs, won't set the world alight but for £15 its worth a go. Is that the max revs of the thing or just a an indication of what it can deliver?

Ian
the 440 cu ft seems small for one of these things, are you sure you haven't missed of 1 off the front? as you will know these are usually fitted to 5 litre plus american lumps, 440 cuft/ min gives 3.3 litres a 7psi and 6000 revs (60000 on the supercharger), as they generally deliver boost exponentially then you are looking at 3 to 3.5 psi at 3000 revs.
Stick a 1 in front of it (1440 at 60000 revs) then you could feed a 5.7 litre with 8 to 9 psi max boost and running the unit at say 50,000 rpm on the supercharger and 6000 revs on the crank, this would give a flatter boost curve and seem more like a typical kit and application.

wow nice find!

paxtons are lovely superchargers but americans dont seem to use them very often.... probably because they dont have the look of a large weiland poking out your bonnet
