After some years running with no problems something happened this summer. I had finally got the a/c working very well (after fitting new condensers). Returning home, engine refused to stop on the ignition switch. But what was incredibly worrying was the fact that the ignition switch had become...

I wonder if anyone has the wiring diagram for the a/c side of the GTD? I am referring to the original installation, small condenser on LHS of car in engine bay (now being thrown out!), with a binary pressure switch. I am in process of upgrading the system but am a bit in the dark over the...

Due to a forced cancellation, I have a pair of admission tickets for the full weekend, including paddock, available for sale. I can split and sell one set only if there is interest. Also available is a GT40 area parking permit for the full weekend.

Just wondering... I bought the car a while back, and cannot get detailed info on the engine internals. Moderate power (250), 4-barrel Holley, conventional valve gear. Of course max revs will go well past peak power, but on our lovely deserted Scottish roads :-), I'm just wondering how high I...

People, I have just fitted a new UN1-013 box to my GTD, and am wondering if anyone has any guidelines on setting up the cable connections, please? I have found some very brief setup instructions for the Lotus, but frankly they are not much help, other than to infer that the setup is rather...

I'm still busy researching alternative gearboxes for my GTD (engine is a 302). I have narrowed the choice down to two, both based on the 3.44 final drive. The UN1-013 was originally specified for the 21 Turbo. The other box, UN1-07 was specified for the Alpine Turbo. The boxes are very similar -...

Peeps, I need to educate myself in depth concerning how the 302 functions, and how it can be tuned. I have dug about for suitable documentation, but frankly have not been impressed so far. Perhaps you have found just the book - do let me have your recommendations! Thanks Peter

I have had my GTD/40 for a little while now, and have always felt it was seriously under-geared. So this week I went out onto a quiet stretch of road and made some measurements, road speed as indicated by GPS versus engine revs, in increments of 1000rpm. The results are attached - a screen shot...

The topic must have been covered, but apologies, I couldn't find it. Any suggestions for a mildly tuned 302 with hydraulic tappets and a high pressure oil pump (75psi)? The issue for me is whether there are oils which can stay in the sump for extended periods. The car doesn't do big mileages...

I am starting to get deeper into the wring on my GTD, but am hampered by what must be the 'n'th photo-copy of the original hand drawn wiring diagram. Although the circuit lines are still decipherable, much of the text has vanished into a black sludge! Does anyone have a decent quality wiring...

People, I have a 1989 GTD, and am in process of changing the steering wheel. But I have a problem - not sure where the steering column was sourced from on this car. I need that information to get the correct steering wheel boss. Mick at Southern thinks, but is not absolutely sure, that the...

It is not obvious where I could have placed this note, so I am ready to stand corrected! Whatever, here we go. I'm trying to locate William. The only connection I have is that he bought a GTD in probably 1990, coloured white and blue (not sure if this was white with a blue stripe, or vice...
