    Hi All,

    Thanks for the ideas

    Bustamif, I'm totally behind you on this one, that's why the pressure returned to normal by turn 2 after the flag. Now comes the other questions, why not in the previous race? and any ideas how to get rid of it?

    Regards, Frans

    Maybe a dry sump engine? There's a bloke in NZ building one I'm told.....

    Hi Frans,

    Even dry sump systems have their problems. Worn gears in the pump such as a chip or pitting can cause it. Porsche engines (dry sump) in the 1970’s had a problem at constant high revs around 8,000. The solution was to remove the oil cooler from the side of the engine and fit a small anti-froth swirl pot in place of the engine cooler with a larger front cooler.

    For your wet sump engine I would be looking at anything at all that has changed in the oil system including any fittings, cooler, pump and hoses. I recently heard of the internal wall on some very expensive oil hose that closed up the inside diameter on the scavenge side enough to reduce flow. The level on the dry sump tank went up as revs increased but the pressure remained OK.

    The last thing is of course the oil if you have not changed anything in the oil system but are using higher revs than before or the same revs for longer periods of time. That topic will get you 10,000 opinions on oil. Every person who drives a car has an opinion on which oil is best and why.

    If you can get onto a senior engineer with an oil company, provided the engineer is involved in the race division, you will get a good opinion. Back in the day, I recall some cars at Bathurst with sponsorship from a well-known “high performance” brand of oil had severe frothing problems. They used to fill the well-known brand containers with a genuine race oil. Oils aint oils! There was another high performance high profile oil with an additive which came out of solution at high revs in racing conditions, the additive blocked oil galleries and caused big failures before the cause was found.

    Bustamif, you are way out of my league. Very interesting and thanks!

    Years ago, BMC had a big problem in UK with Austin/Morris/Wolseley 1800s seizing up on motorways. The story that I read at the time was that all had a similar background, careful doctors and engineers who really looked after their cars. All had been topped up generously before the big trip. I believe the problem was frothing and they solved it by shifting the dipstick "FULL" mark a bit further down. If true, and I think it is, it makes perfect sense to me.

    Hi All,

    Queens birthday! At least one good thing from her.

    I've been doing some maintenance on the race car and noticed the vibration from the brakes in the last 2 races. I also noticed some underbody panel damage from a time I went farming. That cause a small restriction in the waterpipe going to the radiator and one of the carrier brackets bent out of proportion as well. All that is now replaced or panelbeated and ready to go in. Oh, and a new accelerator cable because I noticed at the last race that a strand is broken which I gently wound back into its position temporarily. That is very dangerous because if that strand goes into the outer casing there is not a spring that will return it.

    The discs, all newly skimmed and grooved.





    The under panels, well abused but back in basic shape.



    And the saddle is replaced with a new one from my sponsor.



    Regards, Frans.

    Hi All,

    Attended our prize giving Buffet Dinner on Saturday night and looked forward to the meal because there was no chance of a prize due to all the doings and screwings during the season. Well, wrong! I did get a prize. A Booby prize!

    As posted previously on this thread: "Test done and passed. But.........involved in a get together. Started from the 3rd row and moved up to be sandwiched between an Alfa and BMW 2002 Ti in the 1st row before turn 1. The Alfa on the left closed the gap (right hand turn) and I turned him sideways although I was pulling out of the sandwich at the time. Then the BMW hit him in the side and a Volvo hit the BMW from behind pushing him harder into the Alfa. Bad damage on the Alfa and couldn't race further, BMW went home. I have body damage left and right side and wheel alignment bent."

    And then my way of seeing it: "I keep on thinking who's at fault. Then I feel it is not me. I'm the one that has to do it all myself. Not one of the others work on their own cars. So I'll never look for trouble. cos I'm an angel you know."

    Whatever, I was officially blamed for the incident/accident by the superiors who knows everything and who was involved in this skirmish as well. So I said "Okay I'm sorry" and got it over and done with.

    The prize was handed to me with a speech explaining the severity of this incident where the 7 entries of this informal race of ours was reduced to 3 because of the 4 cars involved. (If I do it, I do it well!!) The message was; "Please measure the gap before you take it"



    Regards, Frans.

    Very funny - my undertray looks like that too.... Here it is after the road from Menindee to Ivanhoe in NSW, before I beat it out, yet again, and gave it some black paint, also "again".

    Hi All,

    So, I'm changing my mind and going back to what was said in these threads at the time. The mechanical gauge is sluggish even though it was bled. It doesn't stay bled. I went to 'Classics and Caffeine" today with the race car after he was standing for a long time. About 10 mins away from home the pressure still wasn't giving the correct reading.

    I have decided to bite the bullet and buy a VDO gauge and transmitter. That will arrive soon and replace the mechanical gauge. I have no theory why it wasn't good but I have noticed this for a while. All you other guys were right!

    Regards, Frans.

    Very strange. I guess they are Bourdon gauges and eventually wear out? My VDO unit is mechanical and dates from 1974, always very responsive (bled) and on its original nylon tubing. Still, a new one ain't a bad idea. Have you a big red light too?

    You need a separate o/p switch set at your chosen minimum pressure to operate a proper light show.....like this.....
