--Ted, neat set-up and cool pics! Thanks for posting the process as well.
Did you install that radiator with the return on the PS for clearance on the
box intake, or was that just a coincidence?
--I've wanted to do something similar for many years, but unfortunately I
filled that real estate in the engine compartment with external oil filter, and
accusump/oil cooler plumbing! Now for me, it would be tough to get air from
the headlamp bucket without a major reorganization. :(

Jim,

The radiator return was just a coincident, but i will take it.

Here are a few more photos, box is all glassed up and smoothed out with filler
and now in primer,
waiting for spring to paint it. The inside will get a coat of clear coat to
provide a fuel safe surface.

--Ted, very nice work! The over-center locks are a nice touch. I think
this setup will function well! I'm wondering if it may need an adjustment to
jetting? Maybe a small step up on mains?

Update on the Panhard bar

Post by engineerted » Sat Jan 31, 2015 8:04 pm

I spent most of the day removing the axle and fabricating an adjustable panhard
mount.

Now on to the body side mount, I think i will make the hole spacing tighter on
the car side.
The bracket is angled 30 deg. to clear the rim and tire. The lowest position
puts the bar about 1/2" below
the bottom of the diff housing.

--Ted, that looks pretty cool. I've had to reinforce the chassis mount
bracket for the stock location of the panhard bar. I suspect lowering the
mounting point will increase the stress on this bracket?

Jim,
Yes, I agree
I had already added the reinforcement as you pointed out and will add some
additional just to be safe. The goal is to get the rear RC down where the
winning FP spiders had it. I also need to add some bump stops. There is
some witness marks where the Drive shaft and the diff's top mount hit the
tunnel. This may have happen during an off track excursion but still need to
keep it from hitting.

Are you running droop limiters?

Ted,

Where did you get the neat coolant fill tube shown in the picture below

Ralph
I don't recall? Either summit racing , jegs or speedway motors, I will have to
look it up on my email.

--I like Bill Mac's "wishbone" solution, but an added stress on the forward
trailing arm brackets to be sure. Nothing comes easy!

--I've been working on a lowering solution on the rear of the chassis, but
clearance over the diff where you indicate (particularly with new center link)
seems to be a limiting factor.

--My axle droop limiters are simple 2" nylon straps (made from tie-down
straps) with grommets, that bolt through the chassis frame-support adjacent to
the rear springs. I'll never be certain, but when I first installed them I
think I had inadequate free play on the straps that may have limited axle
travel and contributed to a spin.

Better late than never! The hesitation actually turns out to be that the
jetting was much too lean. A fellow VW racer with a very keen ear heard the
engine and knew that it was too lean. We went with a much richer jetting and
increased performance around Mosport an incredible 10 seconds a lap.

We had a lot of trouble disgnosing because we also had a bad distributor that
had much too much play in it - hence masking the issues. Replacing the
distributor (from a contact on this site no less!) and then fixing the jetting
made for a very happy racer!
