Its this car we have to thank for duplex timing chain and gears. The problem of rapid chain stretch due to the extra load of the metering unit drive had not manifested itself with other prototype PI cars at the factory. Bill found himself wearing out a set of simplex chains, and gears every race until resolved by Ray Henderson and his team with a duplex set up.

We took the Atlas, and one of our 948 Heralds to Duxford a few years ago. The wife drove the Herald, and I was piloting the Atlast. In strictly defined test conditions (one passenger each, similiar fuel load, and at least 25 miles of clear'ish A14) we dualed. As it turned out they had similiar top ends, with the Herald a couple of miles an hour faster on the straight and level, but with the Atlast able to catch it on the hills. I have never laughed so much whilst driving in my life, a great day.

Not to say it couldn't still be done, the Atlas nearly did it, and that can't be as fast as a 948 Herald. Cheers Colin If an Atlas can 'nearly do it' then it should be a breeze in any other car. Having done the run in all the big engined Triumphs over the years (TR5, V8 saloon, Stag, Chicane) I was finding the RBRR less of a challenge. Thats why my entries have had progressively smaller engines as time has gone on. Still up for that Triumph Tina combination Jase?

So is the manifold in the picture. Its one of the early mild steel ones that we stopped selling over 15 years ago, but to all intents and purposes exactly the same as the stainless one we sell now (same jig, same manufacturer). The manifold was originally fitted to one of our other Couriers back in the 90's. Its now in our blue Courier I'm currently using as my everyday mota.

What brand of manifold did you encounter problems with?
