Hi Gareth.J. and All
When I ran both chargers to test them the large one would show the fully charged green light but then the smaller one on the same battery would continue charging, I heard recently that it's a fairly common fault and it is seven years old so I don't mind binning it.
I think the flame's a good look Whittie said that was small compared to some when I was driving, don't know why the driver should make a difference, maybe I back off sooner so there's more un-burned fuel in the system when it ignites.
After the RAC event we did a No Limits event at Wannas, the car was double entered for Tuss to have a drive but he was unable to attend at the last moment so rather than waste the entry I got a drive. After the RAC experience we decided to take two cars just incase a tow home was needed, we arrived about 5.00pm changed wheels and did the scrutiny thin then were good to go.
The little bit of fluff you can see by the rear tow hook is Whittie's latest gadget for his gopro, yes it's a microphone just so you can hear the exhaust a bit better.
The event today took in both the long and short tracks with the long first, there was a good mix of cars from stock road going ones to full blown race cars, entries are limited so you're guaranteed to get plenty of runs as people drop out like I did after looping it on the short track, first time in the Zed and first time for twelve years, clearly I've not been pushing hard enough.
Here's a vid of Whittie on the long track in daylight.
Here I loop it on the short track, I pinched a brake on the way into the hairpin and was a passenger from then on.
The event went pretty much without incident but the car was idling rather roughly and we found the linkages slightly out with the front carby being fed more than the others so we adjusted that which made only a slight difference, I found the car to be good under load but Whittie complained about it breaking down at high revs and he said it has a new rattle, I figured that while it was still going those issues could wait for another day, this is a sign we've been having fun.
A few days later I put it up on the jack stands and went straight to the rear gear box mount which has comprehensively failed so is touching the gear box housing again causing the rattle Whittie heard. I decided that given both the time of year the fact that Whittie is off again in a couple of weeks, a patch up would do for now.
The idle hasn't improved and it's as if compression is down in one cylinder, I re adjusted the carby linkages properly to eliminate that as a cause and then considered doing a wet and dry compression test thinking that I had possibly set a valve clearance too close, when I removed the plugs they were their normal rich looking selves (we run Bosch Super4 plugs) so I gave them a clean and refitted them but that made no difference then it dawned on me that they're about eight years old and as good as they are they're not going to last forever so I fitted the original near new NGKs and that made all the difference, it's purring (sort off) once again, we do have another new set of the Bosch plugs but I'm going to leave the NGKs in for a while to see if there's a noticeable difference in performance.
That brings me to our tyres, I'm really impressed with how evenly they've worn over the last two events so I'm thinking the suspension settings are just about right although I'd like to try a bit more neg camber on the rear, I doubt it will get any more caster on the front because it's quite heavy enough to steer as it is. We are currently running a set of aged Dunlops which probably passed their prime while they were still on the shelf but they were not expensive, we didn't want to waste money on a good set of tyres knowing that the car would spend much of it's time sitting idle awaiting Whitties return so they are what they are it just means we're not currently seeing the times we feel are in the car. Whitties goal time is 68sec on the long track and given that he did 70.45 first time out when he briefly held the lap record for the speed event series on a worn out set of Yokis that John Fowler removed from his 911 Porker, we're confident that with a bit more tweaking and plenty of seat time it's doable but talking about it is the easy part, we'll have to wait and see what happens when Whittie returns.
Here are the front tyres as they came off after No Limits, when they're cold they're rock hard like taxi tyres, you can clearly see the aging in the tread grooves.
Rears as they came off.
So with the car good to go for the WhoopAss Wednesday drags all that's left to do is a little detailing.
