Round 2 of this years Tasman Cup was held at Dave Grays Mornington Park track. This track is one of the smaller tracks in our group,BUT does provide some good racing. The track was built by one of HMCC's founding members and is based on the original 1967 HMCC Club track,just scaled down. Posted Image
Rob Golley helped marshal duties along with 4 other HMCC members. Drivers for this round are myself on Lane 3, Rhys Filbee and Adrian Gray on Lane one.
The Stray lotus is Rhys,s Club racer that he ran for comparison,it would have finished in four place, just behind John.
Dave gray also put his BRM in the field even though it is getting tired it would have been a good midfield runner.
The winner is Slo1quick again! He finished about 1.5 metres ahead of my car with John Batich a lap behind my car. This is a very well presented and quick car scoring the fastest race lap also.
Some of us though Rhys drove like a girl,then he turned his back on us!!
Thanks very much to Dave and Adrian Gray for hosting this event and having us all there two weeks in a row.
My drivers note need to be sorted and I will post then ASAP.

My notes on driving the cars at Mornington. No1 Quick car but steps out very easy under acceleration making it hard to drive consistantlt No2 Handles well,but the motor seems well down on grunt No3 What can I say very good car and very fast. No 5 Lacking power and when pushed hard to try and get good times suddenly lets go and rolls. No 6 Just lacks acceleration out of the corners No 7 Smooth seems to handle well BUT very little grip on this track. No 8 Very good car easy to drive. No 9 not as smooth as it should be,but good car. No 12 No problems good car No 14 Very good not as fast as the top cars,only thing I would try is a gear change. No 17 Motor seems down on power or tight. No 18 Very good car no quirks No 22 just sound like tyres are out of round. No 41 Handles well But sounds like the motor is working hard,gearing? No 56 Motor just not up to the job,handling good. No 60 Fast car,would do better with more grip No 67 May benefit from a gearing change. No 71 Gearing not as smooth as it could be. No 78 No quirks or problems.
Rhys made the comment after the race that is is the best lot of Proxy cars he has driven,apart from Davids lack of grip all the others were good to drive. I have to agree there are no bad cars in this lot. It is just that the front runner are getting better each year. Well done to all the builders. IMO each car should get a fresh run in motor and new tyres each year. The biggest difference in any of the cars was tyres and a few tired motors. I am surprised that the Gage tyres seem to vary from car to car,either age or preparation must be the difference.

Many thanks for the report and pictures Phil. The lack of grip is a puzzle, the tyres were new and prepared gently. There is a spare set of wheels and tyres in my box if anyone wants to see if they work better and it’s within the rules to change them.
Thanks to all the drivers and marshals and congratulations to the top three.
Great report Phil,congrats on 2nd. A very close finish!
Hi David. The rules will attract a 10 point penalty for a tyre change. Did you prepare the spare tyres differently?
Do you know what shore rating the RS tyres are? I stand to be corrected on this but, to as far as I can remember, the Gage PG tyres tyres are 30 shore and his XPG's are 20. I run the PG XGPs'. I'd be interested to know the sequence of how you, and others, prep their tyres (tires).
I struggle with 'know how' when it comes to prepping rear tyres, and am no club racer, but have had some success doing the following.... Whatever the tyre used with any proxy. I use a 400-600 grit dry, very gently, as to not build up heat in the tyre. This is to get the tyre to dimension. Then a progression of finer grits, all wet, till I get the tyre to have some tackiness, or stick to touch about it. Just sharing what I do.
John Batich, Lenny, and Terry are using RS tyres also. Whilst I did not notice any sheen on them they were all fast paced cars at round 1. Callan is also using the RS tyres which had a good result here too.

Stu John,Callan,myself and the GK are all using my tyres, they are using RS wheels only. John seems to be able to get more from my tyres his preparation. Looking st the Gage tyres I have here I think they may be 40 shore and 30 for the XPG? My tyres are all 40 shore. We tried some 30 but found them a bit too soft for our tracks.
Thanks for the correction Phil. I now recall Terry mentioning, somewhere, running the standard PG tyres. Lenny is on the Gage tyres too. I have to be more careful when looking at the columns in the tech data.
I see you are on Gage tyres too David, XPG or PGT?

My tyres are XPGs. I prepare them using a truer and increasingly fine grit wet and dry and try to keep the everything cool with water. I didn't do anything different with the spare set so probably no point in changing to them although a 10 point penalty is irrelevant given my car's horrible performance to date! I suspect I'm not patient enough in my preparation and don't get to the point where there is some tackiness. Hopefully I'll learn for next year's Tasman.

the next time you need tyres of these sizes give the PGT compound a try, I used the XPG for ages and often found them to be inconsistent,
When I did try the PGT's I found them to be very consistent, they didn't go "south" during a long run and in the end have proven to now be my tyre of choice, Chrisguyw also uses this compound and has made good comments regarding this tyre.
