    Door and Hood Gap Sealing

    On the RCR40 - Has anyone come up with a good method for sealing out road debris from the gap at the door hinge? I was ending up with a lot of gravel and dirt flying in so ended up cutting out this shape from a 1/8" thick piece of neoprene rubber that filled the entire gap including the bit at...

    Bundle of Snakes Clearance Issue

    So my exhaust headers just barely clear the crossmember. In fact, one of them is ever so lightly resting on it and the other has a tiny clearance (maybe 1/32"). You can see in the pix that the part that is interfering is the "thinner" diameter and where the collector slips over the header tubes...

    Vintage Air Mini Gen II A/C System Issues

    Anyone using the Vintage Air Mini Gen II? Mine has been giving me fits and I’m just about to give up on it. System is installed as per instructions and all fitting crimps except the two connecting the compressor to the high side and low side were done professionally using a massive hydraulic...

    Heater Hose Routing Issues

    Anyone out there using this layout for their heater hose routing? I've got a T-fitting in the coolant line coming into the radiator (right side of the picture) going into the heater core, then back out into another T-fitting that joins the flow out of the radiator and back to the water pump...

    RCR40 - Dragging Brakes

    Coming up on 500 miles on a new RCR40 build and getting nicely sorted. I have noticed that the car is crazy hard to push on a flat surface in neutral after coming back from a drive. Jacking it up, I found that the brakes are lightly dragging as the wheels turn with some effort. Cracking a brake...

    Windshield Glare

    My RCR40 has a hazardous degree of glare off the windshield which I think is coming from the dash. In low sun angle conditions, it can be momentarily totally blinding. I finished the dash in Wurth Black Satin Trim Paint thinking the low sheen would be suitable for the dash but now I'm wondering...

    Vintage Air Mini Gen II - A/C Not Functioning

    Finally got the heat side of this unit working (bad potentiometer) and now can't get A/C to blow cold. Fan motor works correctly at all 3 speed settings but doesn't seem that the compressor every switches on. System was vacuumed, leak tested, and charged. The Vintage Air Mini Gen II has a...

    Weber 48IDA Accelerator Pump/Discharge Valve Sizing

    I am slowly dialing in a set of 48IDA's having changed choke sizes, main jets, float heights, etc. It is 95% improved from where I started and one of the only lingering issues (other than the 6.5mpg fuel economy!) is a stutter/stumble on acceleration through about 3,500 rpm that feels more rich...

    Coolant Temperature - What is Normal?

    So I am reaching the point in the build where I am finally on the road and, having worked out an enormous amount of kinks, each drive is getting exponentially better than the last! I dare say this may even become "fun" soon at this rate! ;) To be fair, the vast majority of issues had to do with...

    Expansion/Recovery Tank Plumbing Doesn't Seem to Function As Expected

    I am wondering if my Canton expansion/recovery tank setup is working properly. I am using a Canton 80-200 Fill Tank at the highest point in the cooling system and have the barbed fitting in the side plumbed to the bottom inlet of a Canton 80-201 Recovery tank placed down low alongside the ZF...

    MSD 6AL Issues

    I am encountering a no-start situation with my MSD 6AL. Motor is 363ci with 4x Weber 48IDA. MSD Distributor and Blaster 2 coil. Car has been running fine and recently wouldn't start. Repeated cranking drove the battery down until it would need to be recharged to try again. Seemingly randomly it...

    RCR40 Parking Brake

    Has anyone had success installing/adjusting the standard (short handle) parking brake? It seems no matter how you set it up, it either locks the wheels or lets them slip. It is just not possible to get enough "clicks" on it when pulling given the short handle design. Using the supplied Wilwood...

    RCR40 Fuel Tank Capacity

    Does anyone know the exact capacity of the tanks? I’ve got a mismatch between fuel sender (Speedhut) and fuel gauges (Smiths) where it reads 2/3 when totally full, then sweeps randomly back and forth form zero to 2/3. I’m thinking of using a unit like Meter Match to see if I can make it more...

    Weber 48IDA Heat Soak/Hot Start Problems

    RCR40 is finally on the road after just over 3 years build. Massive thanks to Chris Kouba, Ron McCall, Mahlon Miller, Dennis Quello, and so many others on this forum without which there is no way in hell this would be anything more than a pile of bolts at this point. First few drives have...

    Steering Rack Stiff/Tight

    First drive on RCR40 today!! Massive shout out to Chris Kouba without whom this day would not have been possible (and who was crazy enough to ride shotgun on the first drive!) :eek: Many thanks to this talented, generous man! One issue noted was the steering rack was very tight making steering...

    Avon Tire Pressure

    Apologies if this has been covered somewhere but preparing for first drive (!!) and wanted to inquire what tire pressure folks are using with their Avons. Using BRM wheels if that matters. No plans to ever track, just driving around town and, given where I live, unavoidable on some gravel roads...

    Coolant Type and Quantity

    What do folks recommend for coolant? The green stuff or something more exotic? 100% coolant or diluted? I have heard it cools better when mixed 50/50 with water. Also, what is the approx quantity? I am using a Dart 302 block bored to 363 with the standard RCR aluminum radiator, 2 quart...

    Registration Process - Washington State

    After 3 years and numerous points of nearly giving up, I can't believe it is actually time to think about registering this beauty! This would not have been possible without the tremendous support of this GT40 forum community and many great friends who helped me overcome obstacles -- thank you...

    Dual Tank Plumbing Advice and Considerations

    Hi all, Looking for advice, suggestions, schematics on how to plumb a 2 tank setup for an RCR40. I am planning to run the tanks independently with no crossover and feeding a quartet of Webers which are plumbed in series. There is no provision for fuel return, so will be plugging those holes in...
