Interesting line through that corner!

Correct me if I'm wrong but on loose surface I believe you enter a sharp left hand turn by starting on the left then turning right, then left, which brings the back end around to make the left hand turn under power as the car swings around the corner.

The only problem with that theory is that's not a loose surface it would've been bitumen. (pretty rough and ready bitumen but bitumen just the same)
Any attempt at doing a Scandinavian flick in a car with such modest power and as 'interesting' handling as a Hillman Imp is always going to be entertaining to say the least! [:D]

Pete Geoghegan in a GT 500 Cortina had cut me up over skyline, trying to get past before the esses. Some of the Imps were pretty slow.

He had pushed me off into the dirt on the left, & I had done a bit of rallying getting to there.

You can see the dirt I had dragged behind me as I got back onto the black stuff.

I caught him, & went under him into Forrest elbow to show my annoyance. He got a hell of a shock, finding me just where he was planning to go. He didn't expect much to keep up with him down the esses.

That's why I thought it was loose surface. Can't see gravel to speak of but I thought maybe a dirt road that can be pretty smooth.

Now we know the story. (Many more where that came from I'm sure)[:)].

I retested, this time more careful. There is air escaping from the oil filler hole, but not much...no vapor or visable oil. If you put your hand over it, it forms a vacuum. Stronger vacuum the higher I rev. Is this Correct? I am waiting for some parts, to change the back to oil canister. I will check compression then.

This is right as the suction at the intake manifold sucks through the canister(s) to the valve cover to suck the vapours from there into the engine to be burned.

Yes! That vacuum is correct -so you should NOT have any oil escaping from dipstick/seals etc.
Well done on the Imp Hasbeen! - built just 15 miles away from me... Fantastic engines and gearboxes - not so sure about the rest of it.... I had a plan to put the engine and box in a Mini, driving the front wheels - but never got round to it - sold the parts to a Clan Crusader owner not many years ago.

bmcecosse, I still have a photo somewhere I think, of that Imp doing what Imps do best. Lifting the inside front wheel way off the road, coming out of Murrays corner, the one into pit straight, at Bathurst. It has a Viva behind it with it's rear wheel almost off the road.

I'm out most of today, but will try to find it, & post it here later, if I can.

You mean like this? When I did the Imp as a "Mystery Car of the Month" at one of our club meetings I said the picture proves the Brits will race anything. I guess the Aussie's will too.[:p][:D]

Yep, like that, but that is a mild one. Actually when set up properly, they were very nice handling cars, very stable. Remember the first Lotus Elite was hailed as one of the best handling car of the early 60s, & it did exactly that.

In the Bathurst race that year, the well driven ones were the quickest car down the esses, by a fair bit, & it included a wide range of the production cars of the day.

My second car was an Imp, great little car - when it was running! Once you got rid of the radiator ducting you could drop the egine out in 15-20 mins, just put a box under the sump, unbolt the bellhousing and crossmember end bolts and push the car away. Just as well as it seemed to need to come out quite often.

Did they all have the pneumatic throttle, or was that an optional extra. A friend had one, and, when it developed a leak, had to pump the throttle to maintain speed.

It would out-handle Anglias and Minis, while pumping furiously at the throttle pedal.

Hi Bruce, the pneumatic throttle, that implement of the devil was only used in the earliest Imps in Oz. What a dreadful thing it was. The only time you could be sure it was fully open was stopped, bonnet open, checking at the carb, with someone else working the pedal.

Down Conrod you were holding at least 50lbs on the pedal, because you couldn't believe it had full throttle, at top speed, [78MPH]. I think I posted on here previously how I made the front page of the Sydney Morning Herald, when a mate gave me a tow down Conrod, I it was timed at 107MPH.

We found the problem with the UK car industry with that car. We picked it up from the company with 4 miles on it. It had 17 when we stripped it to detail it, but some of the big end slippers were so scoured they had lost about a third of their area.

We got half a spoon full of swarf out of the camshaft alone, no wonder they did not last. Here is that pick of the imp, followed bt a Viva, with another F1 driver Spencer Martin driving it. Which would you like to be in?

And just for good measure another wheel up handling car, my Morgan +4 in about 64 at Warwick farm.

Hope you like them.

Sorry about the size, you can't expect too much from an old bloke.

Ron, Help.

So, back in 1964 in the Morgan +4, the car lacked fake chromed wire wheel covers, no roll up windows, and that fly screen would provide little if any protection for my bouffant hairdo that was so popular back then. I take it the air conditioner was also not working that day? But, those running boards have a charm all their own.

You say this was a competition event, but it looks exactly like the weekly Monday morning rush to the Walmart when they mark down the meat from the weekend. And, watch out for the widow Pickleby, her big bomb Buick hasn't had the brakes fixed in years.
