Supercharger for V8 on eBay

Tim where are you

I wonder what the rich/weak knob is connected to in the ECU? An alternative to the rising rate pressure regulator with a little extra circuitry - any thoughts Ian?
Possibly replaces one of the fixed resistors on one of the PCBs with a pot. I have seen similar fitments elsewhere... not come across anything in print yet though. Fancy a 350SX do you?
A kit from DPR has instant credibility but I don't know what capacity that sprintex is, it may not be up to blowing a bigger engine. Supercharging a 350 doesn't make financial sense when you can buy a bigger NA engine so (relatively) cheaply. Worth a call to the seller (or to Dennis himself) to confirm the spec before spending money.
Edited to add, from the look of the parts the blower itself is mounted outboard and in front of number 1 cylinder. You might be lucky and find you can still get at the plugs with it fitted ... or you might not. Makes quite a big difference to the practicality of it.

Steve,
Good question. Will it fit?
Depends where you site the blower. The intake looks to be a modded standard item and thus the charger to plenum pipe could be routed as needs be depending on where you site the blower. Your car is PAS if I remember correctly so sitting it under the NS head on the LH bank wouldn't work and also there's the chassis/manifold clearance issue.
IMHO I wouldn't bother a)Packaging would be a PIA and b)SC of the RV8 through the standard intake causes some cylinders to run lean and other rich and often ends up in melt down (I saw a web site on this once - I'll try and find it) (This is all IMHO but to and extent based on experience of S/C Mustangs & the original P38A Range Rover 3.9 S/C programme (engine which was planned before the programme changed to 4.0 & 4.6 NA).

RPI are heavily biassed against superchargers, with good reason: they don't sell them. The problems RPI refer to are caused by putting the blower directly over the inlet manifold (where the trumpet base would normally go) with a very shallow 'plenum' to distribute the charge down the length of the inlet manifold. There was a fairly standard kit based on this approach which was notorious for having air/fuel distribution problems. It was based on an M90 which has a small outlet port right at the front, so the front cylinders got an excellent air supply and the rear ones got anything that was left over.
Force-feeding a standard injection plenum from a remote supercharger is a much more sensible approach and there's no reason to expect any distribution problems. But packaging a remote supercharger can be tricky, and there's no guarantee that a kit designed for a different car will even fit yours.

This kit looks like the ones Brian Luti at Calander garage (a TVR dealer these days) used to fit to Range Rover series 1. The blower sitting on top of the left hand Rocker cover. On RR series 2 we had serious issues with the distribution of the charge in so far as it going evenly to the front and rear pairs of cylinders when using the standard plenum. The programme used a revised set up to even this out due to difficulties in calibration but was later canned in favour of the big NA route - thankfully as we can now get good cross bolted 4.6 base engines. The kit shown at low boost levels would probably work well in it's original application as Green sais, i.e. a RR series 1
At £500 notes it'd be worth the challange on a standard 350 unit but IMHO I wouldn't risk it on a larger, tuned TVR.
