Hi Keith,

It was an excellent weekend thanks, 3rd place on Saturday (with a new personal best time for this car), and then a 2nd place on Sunday, with another improvement on my PB.

There's a bit of a report at this link, and you can also access a PDF file with all the times on it if you are really bored!;

http://gurstondown.org/latest.htm

The Mini of Neal Masters that was always beating me last season was the one quicker than me again, he has a brand new KAD works engine for this season, with all steel bottom end and 9,200 rpm capability.

It's a monster, he's pulling out between 4 mph and 7mph on me at the 2 speed traps at Gurston.

I have a few more developments to implement before the next race, which I think will just about put me on equal terms with him.

I'm going to fit ARP rod bolts and whack the rev limiter up from the current 7,500 to 8,000.

That should allow me to hold onto 4th gear for long enough to avoid the 2 changes to 5th I was needing to make with the new Quaife gear cluster fitted.

I may also try and find a longer 4th gear ratio, but that could prove tricky as Quaife no longer make parts for the F10 'box.

Apart from that I was suffering a leaky brake bias valve (leaking from the unions), so I need to sort that out, and the new lightweight lithium race battery only held charge long enough for 2 race runs before it gave up!

sounds like you had a great day, excellent result too!:thumb:

Are you allowed to use a steel bottom end? Lairier cam and rev it harder? Nitrous etc?

Nitrous is not permitted.

An all steel bottom end is totally ok, it's just I don't have the money for one.

page 58/59 gives times for the meeting. colin needs to find about 0.4sec to head the class, but just check out the other stuff that the little nova whalloped on the hill.

Good results Colin, you can only get quicker

Any fresh pics or vids from the event Colin?

I've put out a plea on the main hillclimb website for videos (I'm keen to see it myself!).

If I get anything I will post them up on here.

i guessed you were pretty busy trying to go up the hill quickly and not trying to get piccys.... any tyre warmers allowed in your class?? cos your motor must be pushing out at least what the mini has..

No tyre warmers allowed in hillclimbs or sprints.

According to the rolling road at BTEC Racing I have 220bhp at 8,188rpm.

But I have it rev-limited to 7,500, where it is showing 195bhp - precisely the same as I am told the KAD Mini is producing.

So getting the revs up is a definite priority so I can see some more power, and benefit from holding on to gears for longer.
