Supercharging a Rangie

[Guru036]

I have a 89 4dr Range Rover with a 3.5L EFI and Auto. Great car for what it is. I mainly use it for weekend fun, long trips and towing a car trailer to comps and weekend trips with my series II or buggys on it.

The Rangie Tows well, but I would really like abit more grunt. Thought about putting a 4.6L in it but would have to stuff around with changing the EFI system along with many othere bits and pieces. So I was thinking of getting a supercharger (say off a commodore or similar) and fitting it (make custom bracket and piping) and run around 7- 8 PSI, nothing massive but enough to make towing that much easier. I thought with lowish psi I could keep the stock internals in the motor.

What do you think? has anyone done this before??

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

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.

[mcrover]

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.

Really? I never would have guessed:bangin:


ECU is scrap regardless, stroker of blown;)

I know of 2 succesfully blown rover motors (both roots type) and both are on stock internals, wtihout failure and both are driven not very kindly:twisted:.....despite what all the nay sayers say:mad:

Anyway i'll leave you in the hands of all those that say it can't or shouldn't be done....and all in all your best to leave your motor stock as its all to hard or buy an isuzu and leave it VERRRRRRY slow and N/A because its easy:D

[beforethevision]

Anything can be done, just research it. The M90 is a nice supercharger, just dont replace the plenum with it. Relocate it and intercool it and it will run beautifully at good pressures for ever. An ECU is a MUST for anything over 2 or 3 psi. and will benefit all scenarios.

I am working on a similar situation for my freelander using an M45, when its done it will be posted, and probably heard :P

[mcrover]

Traditionaly, you can build blown engines 2 ways but there are grey areas leading to both,

1. A lot of engine and a little SC
2. A lot of SC and less engine.

So in saying that, the problem with fitting small SC to existing engine isnt so bad but your basically still Little + Little as the engine isnt built for that.

But It will work, the grey area is for how long and to what extent.

I would be looking at what you can do with the existing engine and after market ECU, maybe exaust and cam, ports valves etc and once youve done that, then look at SCing the whole lot if your still wanting more.

Nothing wrong with anyway which anyone goes.

Can you please explain what the 2 you know are running please?? keen to hear

Sorry mate was more pointing that out for everyone else.

And I am not against supercharging. I have wanted and prob will still want to do it for a long time. :)

The amount of times i catch myself ont he capa performance site just browsing is scary :)

Gday mate, my father in law has had his 1990 Rangie supercharged since the day he bought it brand new. He has a Sprintex on it. The original 3.5 lasted up until 2005 when one of the pistons let go, so he bought an imported 3.9 and fitted wolf engine management I think it was and bigger injectors and together with the super charger it is awesome. It was awesome before with the 3.5 though! He is just getting an auto gearbox fitted at the moment and will see how it goes then!!

WTF is that all about?

u know 2 motors blown and driven hard....
OK... Define HARD....

And whilst your at it.....How about...

What sort of power are they making?
How often are they driving?
What ECU did they change to?
Injector change?
Water injection?
Intercooling?

It can be done.. I agree... I "dun" it ;)

But I can give you 2 reasons to do it, 10 reasons not to...
And better performance without it spending less dollars.

The original motor lasted till 2005...
Cool!
How many km's on it please?
How much boost was he running?
Was he using water injection?

Have you got/ can you get pictures? Do you know what boost it runs? if it was stock ECU on the 3.5 ??

Driven as hard as you like;)

You did it? or paid someone to do it?

One is making 138rwhp on a completely stock 3.5 on straight LPG, thats over double a stock carbed 3.5 on the same dyno, The other makes alot more with a 4.6 bottom end and haltech, ones of a dirty old pommy truck the other is an Eaton m90

No water injection nor intercooling

You had a centrifugal blower NOT a roots, completely different charecteristics

ECU needs alterations for a stroker and you injectors aswell, what's your point??

Did you build your stroker yourself??

[cartm58]

if you want to super charge your rangie then go to Jordon Rovers site on we and have a look they do it

if you still want to pursue it talk to Kevin at Jordon Rovers, they are in Perth WA but with today modern communications its cheap to talk

Oh I love this!

I, me, myself did the supercharging on my vehicle.
I fabricated the custom intake, I did everything except make the supercharger, fuel pump and main bracket.

I fitted it, tuned it, tweaked it....

I machined a custom pulley to increase the drive ratio on the blower....

I programmed the Haltech to make the thing go...


And it made 290kw.... :D Would smoke all 4 tyres off the line on dry road (35's) hence heavy wall Driveshafts, custom axles, diff centres, CVs etc....

As for the stroker....
It was a crank, rod, piston kit from the UK...
Fitted to a new block by Bruce Davis....
When the guy wrote the vehicle off I purchased the engine and modified it some more before fitting it to replace the supercharged engine.

But thats OK.... Keep having a go.....

I'm too old to enter a pi$$ing contest with a young buck.

Oh, and for the record....

Our Disco2 TD5 makes 102kw at the wheels with an IC upgrade and mapping changes.... And still gets 9.8l/100km :cool:

Supercharging is good.... Its fun....
And it sounds awesome....

But nothing beats to total tractability of the stroker engine.

Nor the simple linear power output, the use of std pump fuel (not PULP, which the blown ones need)

[beforethevision]

i agree a chipped td5 is a beautiful piece of work. Both the stroker and superhcarger have their benefits, both have negatives. stroker replaces the parts that can break, so its inheirant gain lies therein. Superhcarger can typically be done for cheaper, esp if you get it all 2nd hand, and have no limit to temporary power output. (bar fuel quality)

PERSONALLY, id change the ecu either way, as the rover v8 runs off the computer power generated by a mouse in a wheel. IGN timing could be vastly improved, which will add heaps of efficiency. New coils, porting and manifolds are good either way.

Ive sold my v8 disco, due to it sucking down 25L/100kms. Not worth it to me, a student.

Cheers!!

You seem to be doing a good job in this ****ing contest;)

Can't argue with the need for PULP, Yet I don't know how you can smoke all 4 tyres unless you had CDL and F and R lockers engaged? otherwise it would be front left all the way:p

And tractability?? You had a centrifugal not a ROOTS type blower, different characteristics

I understand you thought the driveability was better in the stroker, compared to having a CENTRIFUGAL blower

Agghh who cares, i'll stick with 351cubic inches and a roots blower, can't compete with 10l/100km but:(

[tombraider]

Yes, I did go centrifugal...

With good reason...

Roots type systems are limited in boost, and on the rover require baffling to even attempt to get even distribution to each slug.

Pull apart a roots (Eaton) Rover V8 thats done some miles and you'll see what I'm getting at...

As for a blown 351 :cool: now theres a thing of beauty ;)

And yes, it was locked up when I span her up!

Yea, i'll be happy with a measly 6-8pounds of boost, boost just of idle makes for a nice square, wont make much more than 350rwhp if i'm lucky but bet it will pull christ of the cross:)

Even the turbo's I had on the 302 with 6 psi was a good thing to drive:) till it caught fire from underbonnet heat:eek:
