Hi all, just wondering if anybody has fitted a supercharger to a rocky 2.8 diesel, as i have been thinking about it for a few day now.

Can't see why it won't work.

Probably hasn't been considered cos the factory turbo intercooled option was always there. Bit less stuffing around.
Like jav said, no reason why not... except cost.
Cheers.

Just looking at playing with a supercharger as i have one laying around in the shed while i save up for a factory turbo motor to drop into it one day.
might change the radiator first looking at dropping in a ford ea one.
The biggest cost will be a belt and new air cleaner setup.

What type of blower are you gonna try?
Do you have overheating problems? Coz my Rocky radiator is very large and cools more than sufficiently... is the EA one much bigger?
Why can't you use the stock airbox and redo the plumbing for the S/C?

Supercharger is a toyota sc14 with the 12v clutch.
The ea one is about the same height but is alot wider, i have no problem with overheating but the temp gets up abit on really hot days, just seeing if the ea radiator will fit as i have thermo fans from a ef falcon in the shed and would like to remove the fixed fan.
the airbox sits where i will be fitting the supercharger so looking at fitting a nissan gq air box that will sit on the engine ( will have to measure one up this weekend)

I wouldn't go removing the fixed fan for electric ones. you'll end up with overheating problems no end.
Probably the best mod if you want to reduce the power sucked by the fan is to fit a viscouse coupling fan off a latter model rocky. Will need to change the water pump as well as the way they bolt up is different. New water pump is less than $150 from memory.
Factory radiator if it's in good nick should be up to the job no worries.
If your overheating there might be other issues.

You'll also need the boost compensator module for the fuel pump off a later model turbo rocky.
You plumb this from your inlet manifold, to the compensator... It increases fuel when boost is created to keep the correct AF ratio.
Otherwise, you will be either running a very rich off boost mixture, or a lean boost air/fuel ratio.

The ford ea radiator won't fit steering box is in the way so looks like i will just flush out the rocky one and put it back in, looking at putting a spacer on the fixed fan to make room for the new pulley. ( was just looking at a bigger radiator for when i get more power)
I have the pulley that i hope to use, just need to press out the centre and make up plate to bolt it up.
Will have to have a look to see if i can get my hands on a boost compensator.

My stock turbo motor will produce as much or even more power than your SC motor... so if they didnt change the radiator between turbo and n/a models you should be fine.Rangie Thing wrote:was just looking at a bigger radiator for when i get more power)

If you have troubles... get a new replacement or a new turbo radiator (if they are any different that is)

just sold an F20/scat with a n/a 1600 petrol motor, on gas, cordia fuel injection, 4agze supercharger, 5 link coil suspension.
very dangerous, if u droped the clutch on the road it would pop a wheel of the ground. cool on road not offroad. i owned it a week.
s/c was hooked to a vacume switch to come on at 3/4 throttle.
u can switch them on and off as they have a magnetic clutch.
would be good to use on a turbo motor to combat lag.complicated plumbing tho
