The Overfinch Discovery legend is true

[vjj]

hello Chaps

update for those following

Chevy 6.3 and most of running gear is now installed



Bulkhead has been painted in keswick green and has been fitted



Note Ceramic headers from Chevy Blazer - they are a perfect fit on the off-side but we have to chop them around a bit for the other side



Gearbox is a ZF HP22 built by Ashcroft Transmissions with stage 2 upgrade(stronger clutches, sprag clutches etc and uprated pump and govenor)together with the biggest torque convertor available and I also had a a late-type Transfer box with 1.2 ratio rebuilt at the same time.

looking good buddy
if go's as good as mine your be well chuffed

ps looking forward to a track day :-)))

[vjj]

Track day - no way!

Drag race - sure thing.

Colin I have to say that TVR engine I sold you has been transformed by the remap at Austec and the fitting of the manual gearbox.

The space mountain ride we had on Monday proved what a fantastic beast it is.

Obviously the old chrysler 3-speed was eating up the power and taking the edge off the torque but now - wow.

Your 90 is surely one of the fastest out there.

The raw driving experience reminded me of my first TVR - a precat V8S

The cam is a 265 piper - originally TVR's own grind was equivalent to a 285 but there is so much torque from mid-range I don't think that with the manual gearbox you need to change it to a torque-specific one.

See you next week

Update

coming along quite well





all engine/gearbox work done - exhaust left to do............twin stainless exiting at the back

main jobs left are final assembly and wiring and the interior.

[vjj]

Couple more update pics

All heavy engineering done

Allisport radiator in - remote gearbox and engine oil coolers in front behind grille.

Final assembly of major parts this week plus electrics

Trimmer booked for Sat 9th Feb

then off to exhaust man

Then MOT and snagging

Should be all done by end of month.

Interesting project!

There is a lot of work going into the build - while you are at it I recommend you ditch the Terrafirma dampers and fit a set of Fox OEM replacement dampers from Prolinx - they'll let you put the extra torque to good use with much better control than stock components.

Paul Jones at Prolinx is a top bloke and can tune them for you if you give him corner weights etc or even take the car to him.

I have his Fox OEM fitment shocks on my RR Classic Rally car but with a few mods. Remote reservoirs with click adjusters for rebound, high temp oil and seals etc. Worth every penny.

I'll second that - he worked magic on the 12 x 2.0 emulsions fitted to my Bowler - 5 to 10 mph increase in cornering speed and lift-off oversteer significantly reduced. They are due for a refresh very soon.

Excellent suspension gives the driver the confidence to use the vehicle to it's full potential.

The TF kit is shorter than standard anyway and gives a 25mm drop and 25% rate increase.

I am having an LSD fitted to the rear axle and then will see what happens - thanks for the tip.

You may find it more useful in the front.
I find its my nearside front left that spins when giving it some moderate power pulling away, if I go full throttle both fronts struggle for grip - not really aware of whats going on at the back end - as I'm busy at the helm trying to keep it on the black stuff.

JE pin the front diff on their fast road Landies.

Looking good by the way.

I agree. Even in my modestly powered Rover V8, it's always the inside front wheel that spins up first when driven enthusiastically on the road.

I was over there today(7/2/12)

Roof is on, they are finishing off the lighting loom and all the heater stuff etc etc.

I will probably get the diffs sorted when i have had a good month or so seeing where improvement is needed.

Ignore the hideous grille - it was put on for a joke.

Hi Guys

here is my first fire-up in the Landy - a bit of rattle whilst the tappets settle then boom - no exhaust yet - just Flowtch ceramic headers fro blazer K5

[eliot]

Good old chevy power..glad the first upgrade i ever performed on the dakar was to bin the rover v8

[vjj]

Eliot

can you see my lovely ceramic-coated K5 Blazer 4WD headers in the engine picture above?

Thank you for the tip.

On the drivers side they dropped in a treat but on the side in view we had to cut them an inch below the plugs, heat them up and bend them in a little to miss the chassis.

We then just welded in a bit of stainless at appropriate angles and had it coated to match - looks factory.

Electrics to finish, roll cage to go on, doors and trim to fit and exhaust and MOT.

Then it's off to scare some old ladies!!!!!!!!!!!!!

Another 500i on eBay:

[vjj]

Yes another one - 500i - 305 cubic inch - 5 litres - about 250 bhp and 300 lbs/ft of torque

At the time the 570 was only 2 grand more...........................................

The 2nd-last Genuine Overfinch Disco is no more - that means Damon Orloff has the last one known about.

There are/were more than you think (in fact there was a 5 litre on eBay the other week).

Are you sure it was a discovery? I saw a 5 litre Range Rover on there for 18 grand.

If it was a disco then that would be great news but a little bird from Overfinch who had been there from the Schuler days in 1985 told me that 'only a handful' of discos were done, some of which were LHD and went overseas.

I guess that means that my 1996 Overfinch Disco1 5.7HSi is very rare. I bought it from Overfinch many years ago and was told it was the only Disco1 with the more powerful HSi engine (multi point injection SBC TPI engine from corvette). It had the steering, brakes and gearbox upgrade by Overfinch, although I later got the gearbox upgraded to HP24 spec (like those in Jaguars) also with upgraded sprag clutch and doubled up flexi-plate. Other things I've upgraded since are adding LPG multipoint injection (by Gordon Finley,Chris perfect), remapped on rolling road, K&N cold air intake, Limited slip rear diff (much stronger), wider track with spacers, walnut look dash plus extra gauges. Low mileage at 39,500 miles.
The only question is its difficult to price should I ever get around to selling. Anyone got any idea?
