Thread: Supercharging a Rangie

Ironic how they're against supercharging, when they're selling stroker motors isn't it

Dont believe everything on the interweb

stroking and supercharging are two totally different things.

In my opinion supercharging is ok but the common eaton setups are not well suited to the rover motors and it is for the reasons explained by rpi. Your best off fitting a snail type charger and using the original intake with afew flow enhancements.

I was looking at this option and only running 5-6psi but i could not get it all sorted out at a price i was prepared to accept.

I wouldnt do it if your not prepared to change the ECU for something programable to get the best out of it.

Nothing wrong with it but as a recent thread along the same lines pointed out that there is normally a lot of sorting out to be done.

I think you could do it on a budget if your not expecting a world of power but I dont know if the increase would be equal to cost if you know what I mean.

Deacons and LRA have both done supercharged rangies so maybe a phone call on what options are available and they could give you a cost, if doing it yourself then work it out mius labour.

Only prob with the turbo type ones is that they are only of use higher up in the rev range where the screw type give you boost from the start but not much up high.

So if the eatons are no good on the rover motors then how come both Deacons and LRA systems are both eaton SC's, and they have got big power out of them with few problems.

I was planning on using a stand alone supercharger and keeping the standard air intake. 5 Psi would make towing that much nicer..

I was planning on doing it as cheap as possible, buy a 2nd hand charger, do all the work myself

interesting artical....I guess the standard ECU is a limitation/problem. I thought running low PSI would be ok.

This is similar to what i had in mind. In the end I decided to change the cam do the heads, and next ill be looking at a stroked short.

As I often say, supercharging is a complex and frustrating business. Top mount blowers on V8's make it almost impossible to design and fit an inlet tract that gives even distribution, & difficult to house a decent intercooler. Using more than 6-8psi boost on petrol engined street cars produces a whole set of problems. you often feel it is two steps forward and one back, or the reverse, when sorting out one of these. Grimace has the right idea for a street engine. The other way is to add a heap of cubic inches with a heart transplant.
