I didn’t order the adjustable petals. Big oversight on my part. RCR didn’t have any but I found a similar part on a Volkswagen bug racing site for 1/2 the price. Needed a different top plate tho.

I went down the rabbit hole with doubling the firewall sound and heat protection sandwich as detailed in Tom’s trackracer. It took him, a master, 14 hours. I have what seems like a lifetime into this and it’s not done.
First I cut a mirror image out in sheet aluminum. Then glued some aluminum stock using JB Weld. Primed and coated with lizard skin sound and heat. Then a layer of dynomat extreme and dynaliner. View attachment 137087View attachment 137088View attachment 137089

Looking good. Who did your rear glass? I still need to have a safety glass made up.

Looks good. I have a RCR slider to sell I didn't like the pedals being up that high in the car so I'm not going to use it.
 
Nice job. A suggestion, if your pedal box is out of the car, you may think to add on the left side a support to put your left foot on it when it is not pushing on the clutch pedal. If you have a non adjiusable pedal box this support may be screw on the side, but when the pedal box is moving the support shall move in the same time.

So I followed the recipe Tom used in his RCR 40 trackracer in make my the double firewall sandwich. I’m finally finished. And just to be true to my build, I had to take it out again and sand several areas back to fit the spider correctly. I missed one small detail. He brilliantly took a 1/4 inch off the entire wall before he assembled it. Smart.

Are you upgrading the firewall window to glass? I am planning to leverage Tom’s build as well, except that my car will only do a few fun track days, nothing serious, so probably won’t do some of his mods.

Yes it’s tempered glass. You get 2 aluminum trim pieces for the window in the firewall from RCR. I brought one to a glass guy who cut a piece of tempered glass 1/2 inch bigger. Cost 50-60 bucks. I then used epoxy to glue it in on 1 side. I used foam strip on the opposite side to seal it in.

Here is my quarterly update. It’s not because I haven’t been putting in the time. My build has actually become obsessive. I’ll start where I left off. View attachment 137045View attachment 137044
I used the alternator and bracket from CVF. It needed tons of modification. View attachment 137048
The teeth of the fan needed to be ground down and the helm joints and rod shortened. View attachment 137050
The air conditioning compressor bracket from RCR would not work at all for me. View attachment 137052View attachment 137053View attachment 137054
Steve, it looks like you are going with an electric water pump. Where did you get the water pump input cover? Cheers, Randy

I went with the Davies Craig pump and the cover. The pump is from summit but I think I ordered the cover from them directly.
Steve, thx much for the info. I currently have a Ford Explorer water pump with the impeller removed, but if that doesn’t work, I want a backup plan.

I am going to try the Pierburg CWA 400 (BMW) with the TinyCWA Tecomotive controller.

I have had some fun with anodizing. My parts came back horrible orange brown gold.

So they went back and I love how they look now.

And I’ll offer a small piece of advice. The 4 bolts at the bottom of the U at the back of the chassis go in before the engine. That was my 4th time taking the engine out. Very disheartening for just those stupid bolts.

Steve, another request. Can you share your plans for the firewall wings? Just yesterday I pulled out some cardboard to make templates. BTW, the anodized suspension parts look great. Cheers, Randy
