Lancia Fulvia At
the recent Castle Combe track day, my car finally made its appearance after what
seems to have been an interminable gestation period (seven years). It
is not and never will be, finished. However,
following an all too brief spell on the track due to a faulty condenser and a
cracked cylinder block (which was due to my negligence!) many visitors expressed
interest in the car. For me, an inveterate fiddler and modifier,
this was very satisfying, as I am aware that specials are, to say the
least, not nearly as much "the thing" as they were in Julian Jane's
day. Anyway,
this piece is neither to be a cri-de-coeur
nor a tedious account of every weld or piece of fabrication until the triumphant
day when the car "passed its MoT with flying colours" - why do they
always say that? (it did actually). No,
apart from a few disconnected jottings, I just wish to express my grateful
thanks to the many kind friends who have helped and also to the numerous
motor-manufacturers whose designers (unwittingly) contributed parts. These I
list at the end.
And
now a little about the project ·
Thanks to Gerald Batt
and Harry's neighbours, the Deadmans, I was able to collect OMY 142E from
Harry's premises after his death ·
25% filler, the balance
being mostly oily filth, holes, cobwebs etc. ·
After about three months
of weekends welding, I had a shell. ·
Since the project was
not done "aircraft-style" - i.e. drawings first (I can't draw) it
developed organically. Examples of this include the purchase of various steel
wheelarches, the three different mounting-places for the oil-cooler, two
mountings for the injection, three radiators etc. ·
Why injection? A number
of people asked me this at 'Combe. was,
of course, aware of the works efforts with the Kugelfischer system, but no-one's
ever told me how much power was obtained. There are rumours that such a 1600
came to England but after fifteen years of Lancias I have yet to meet anyone who
has seen a VAR 1016 Fulvia, let alone an Iniezione!
Anyway,
I was very fortunate to be offered a Lucas 6mm 4-cylinder unit with a Cosworth
drive and 4 injectors at a price I could afford, so then I was committed. For
those who have not seen the car, the pictures show how the installation is
arranged, The metering unit is driven by means of a toothed belt from a modified
rev-counter drive. tract
still further. The reason is that a shorter tract will improve top-end power and
together with injection, provide much-improved throttle response - never the
Fulvia's strong point. Additionally, injection provides superior atomisation of
the intake charge - essential with long ports - and thereby additional
mechanical "octanes" by virtue of a better burn. At
a recent rolling-road test, the engine delivered 110 b.h.p.(and climbing) at the
wheels at 6700 r.p.m. Unburned hydrocarbons were very low - 95 p.p.m. proving
the "burn" theory. Incidentally the power output is equivalent to
about 145 b.h.p. at the flywheel. I am still using the original Cosworth F2 fuel
cam which came with the injection which is hardly suitable, whilst the ignition
timing is actually a guess - we didn't touch it during the test session - there
wasn't time; neither has the cam timing been addressed. ·
More work has to be done
on the exhaust system. I have found that Fulvias respond very favourably to
attention in this area. This may seem a platitude, but take a look at the dismal
exhaust valve-throat area on a standard Fulvia head and I'm sure you'll agree.
Another thing: why did Lancia use the 1300 manifold on the 1600? The fact that
stainless steel was used is really an admission of failure - I've seen them
red-hot! The fact that I have virtually to dismantle the entire front of my car
to remove my fabricated 4-into-1 manifold is another admission altogether of
course! There's really very little room; back to the (virtual!) drawing-board, I
suppose. the
"A" post into the sill structure with further triangulation of the
flitches forward and above, that. I have done away with the troublesome boxes by
simply removing the rear portion of the sub-frame and mounting it where Nature
(and Fessia) intended - in the original place; a lot of work, but weight is
saved and rigidity gained. There are solid bushes (from Barry Waterhouse) and my
ball-race front spring mounts beautifully executed by Doug Ellis. ·
Next? Well, how about a
mechanical fuel-pump (always the Lucas bugbear) dry sump, rose-jointed outer
front anti-roll bar mounts, alloy brake-disc bells etc? It's nice to dream... paintwork.
As I said, it will never be finished....... SPECIFICATIONBody/Structure1967 Fulvia Coupe. Sills reinforced with central membrane, all seam-welded.
