What are you doing to your car this winter?

Post by engineerted » Tue Dec 30, 2014 9:52 pm

This thread has been a little dead this year, so what are you all doing to your
spider this winter?
Doesn't have to be race car related.

I will, start.

1. Changed out the front hubs & spindles, now running a set from a Fiat 125.
Bought a set from
Italy. These are stronger and will provide a better camber curve and a little
drop in CG. If you recall
I broke a front spindle about 2 years ago, not fun running into the tire wall.

2. Going to build a cold air box for the idf's, this will pull air from the
drivers side head light to gain
some cooler air and hopefully more HP.

3. Lower the rear roll center by making an adjustable mount for the panhard bar.

1. drive two spiders
2. Turn a 128 shell into a 128 car.

A great idea - thanks for posting as I have a question

On my race Fiat 124 Spider - I have a hesitation under WOT at ~4500 rpm. This
has been identified as a limitation on ignition as we do not use the vacuum
advance.

After 4500 rpms the engine pulls strongly and has no issues. For racing however
there are two corners where this affects me and put me at a real disadvantage.
The
car is extremely reliable so i made do.

I called around and seems there are not really good alternatives. I know that
one
fellow racer has an MSD in his Fiat - how does that work out?

For the second Fiat - the plan is to install a proper race head and perhaps
move to
side draft carbs - as the major engineering work of moving the brake booster has
been completed.

And a secret Project too. Shhhh

Great Question!

I'm trying to revive a Scorpion before the 2015 Freak Out. This will be my
first freak out so I'm excited. A bunch of us from New Jersey are planning to
attend.

I have to reassemble the suspension on the Scorpion.
The front is treated to all new radius arm bushings, new control arms,new rack
and pinion with new tie rods. Rear Suspension received new control arm bushings
and one new upper strut mount.

Brakes will be replaced by a custom kit with 284mm vented discs and Wilwood
calipers. Custom brackets by TCE Brakes, very helpful. Yes I know overkill!
But paying 300.00 for rear calipers kinda rubs me the wrong way.

Engine, I have a 2L block waiting for HC pistons, hoping to find standard bore
so I can avoid machine shop delays. Then reassemble it with a 2L head,
supposedly a big valve head already redone by PO, FI conversion using Beta
manifold. 40/80 cam on the intake side.

Tranny, I bought a rebuilt one from Mark Rawlings a couple of years ago with VX
gearing. Should make for a nice highway cruiser.

Clutch I have a new Valeo unit for a Spider, Clutch disc and pressure plate
supposedly the same. I just need to find the correct throw out bearing.

"Custom Metal Shifter" from Darren in the UK.

Interior... What a mess. Needs carpet, might try to make my own, Needs center
console. needs a heater box. Might get one from Vintage Air.

Properly Mount the front and rear montecarlo bumpers.

Basically everything!

Get the car aligned, fill with gas and go??

--Hi Ted, haven't had a chance to post a reply yet. Short answer for me is
not much, as I did most of my stuff last year, but I'm still playing with
lowering the rear of the car, with the limiting factor being the height of a
Koni shock in the stock attachment points.

--I didn't know the Fiat 125 spindles were an option as well! How do they
look in a side by side comparison to our OEM spindles? I've got the 132
spindles I obtained from down under, and they are clearly more beefy than ours,
and also result in a little drop in CG. Have you got a source for wheel
bearings and seals for the 125 spindles?

--The adjustable panhard bar looks interesting. If you lower your roll
center in the rear, you will decrease weight transfer in corners, making the
car tighter? Do you also intend to keep the panhard bar level, or will that be
adjustable as well? Cool project! I'll be very interested in seeing how that
works out? If it's not too top secret, send me some pics!

Jim,

The 125 spindle is exactly the same as the 132, so yes they are beefy. I
haven't started on the
panhard bar yet, trying to finish up the cold air box for the carbs. Will post
some pic when I finish
mocking it up.

Hi Jim. Yes, this is stock electronic. I do not know if the advance plate is
disabled. What does that involve so i can ask/check?

This is the 1756. The Plugs are NGK and we tried to swap coils to no avail.

: --If setup correctly, a stock Fiat electronic ignition system will do just

It will rev just fine to 7800 rpms (I never go higher), just has this stumble at
4500. I did notice that at part throttle - there is no hesitation. Wires were
changed as well.

Thanks for the help Jim!

-------------------------------------------------
--Chris, sorry I missed your question on the advance plagte. Vacuum advance
and mechanical advance are independent, but are additive with respect to total
advance at wide open throttle. Vacuum advance occurs with the advance plate
moves in base of the distributor, where the pickup is attached. Mechanical
advance of course occurs when the centrifugal weights on top of the stator
shaft move the shaft relative to the pickup/base plate.

--If equipped, and you disable the vacuum advance by removing the vacuum
hose, depending on the condition of the vacuum capsule and the base plate, the
advance plate can still flutter under certain operating conditions. This is not
usually an issue in many aged electronic distributors, particularly with
inoperative vacuum capsules, because these components can often be frozen in
place. But, to disable the vacuum advance of a functional system, you can
remove the vacuum capsule and actuating rod if you like, or just leave them in
place, but in both cases you need to immobilize the advance plate. Easiest way
is to use epoxy glue on the small stud-ball where the vacuum actuating rod
attaches in a grove under the distributor body. I'll post a pic if this is not
clear.

--Chris, just out of curiosity what NGK plug are you running?
