Valuable information Rob thank you. Those chamfers sound subtle enough to miss, glad I know about them.

Google AI reports my 1500 lump and Ford type 9 combo weigh in at ~34# net increase over an A-series/ribcase combo. While I don't exactly trust AI to get it right, if this is anywhere near correct it seems sufficiently minimal to not require attention/compensation. I suppose I should wei...

5B does exist on the 1500 but in a different form. If you imagine the top surface of 5B is pressed downward so it lies at the same height as 5A and forms a U shape between the rack mounting points, then the front and rear sides are filled in to add strength you end up with that in the 1500. I think this was done so you could fit a fan belt.

Also, I learned just today, that the brackets fo...

Okay first things first: In my OP I reported this to be a negative earth vehicle.
Nyet.
Positive earth, 1967, partially converted to negative earth by a prior owner. I say partial because wiper motor terminals not reversed, haven't got a close-up look at the fuel pump wiring yet.
anamnesis, I said bored, but offended would have been more accurate. My 1979 California car (known hencefor...

I used to work in the car industry on the emissions / calibration side. We stopped using fuel recirculation as it tends to add heat back to the fuel tank - so if you go down this route you need to make sure the hot fuel re-enters the tank away from the fuel supply to the engine.

I'd go for a stand off heatshield on the tank to stop bulk heat hitting it and also shield / duct heat away from ...

Thanks Rob.

That will be worth considering if I have a recurrence.

This was the first time it has happened for me and it's also the first time the Sprite's been in action with an air temp of 32 degrees so I'll try the insulation route first.

I recently discovered the BP Video Library website.

There are lots of motorsport films on there.

Here's an interesting film from 1972, featuring lots of Spridget action and a cameo appearance from John Sprinzel.

There's even a 4wd Daf for Arie!



"A Castrol film featuring seven different forms of motor racing from 1972; Drag Racing, Autotest, Hill Climb, Autocross...

Colin, will the rules allow a high pressure fuel pump and a fuel pressure regulator with a fuel return pipe. This is what modern cars do, keeping the fuel circulating via the tank which acts as a heat soak.

Sorry Chris I’m going to disagree. First the fan isn’t original anyway so painting it black for originality sake is pointless IMHO Painting the plastic fan will alter the plastics chemical make up and can make the part brittle depending on the paints chemical makeup. Also the paint will crack and peel overtime as the fan flex’s. Also, the contrasting yellow will remind one to keep their...

Nice, I plan to use my car to bimble around Warwickshire countryside with the gf, but have uprated it to not feel like a target on the motorway, trying so very hard to not turn it into a racer as I know after spending a fortune it will still be slow !

So you need to focus on getting heat away from your fuel lines, your fuel pump and shielding your fuel tank.

Malcolm I have a copy of Daniel Stapleton's book and dip into it from time to time but it is aimed more at the all-out racer. I should probably have looked to see what he says about the issue before posting.

My track activities are limited to a dozen or so club-level hill climbs each year as well as MASC and other social meetings and leisure runs. I am sticking to Interclub Class 1A Roadg...
