Thread: Supercharging a Rangie

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!!

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.... 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

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)

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

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

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 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

If any of you guys really want to try supercharging....why bother with the hard road of starting from scratch. make an offer for mine. 3.9L low compression. S/C fitted by Graham Coopers. 5psi boost add on computer. Complete with wireing looms all ancilliaries ready to bolt in. 138.6 rwhp with scope to increase boost for more gains. Includes origional ECU.
I just LOVED blasting by Toyos etc on the highway

What sort of blower does it have???
Pics???
