I've heard that Avon CR322 as used by the Academy are now the tyre of choice :-) Some fronts for sale here.
-
Hi Stephen - get the bolts welded to the runners. Caged did it for me when I had my roll cage fitted and it makes removing/refitting the seats so easy
-
Yes please Andy - I shall use it as evidence next time we have to buy tyres 😬 Actually to be fair, Gill does pay half our tyre bill Edited by - Shaun_E on 1 Jul 2014 12:27:01

AD08R are list 1B but the normal AD08 is list 1A so it depends which class you fancy for sprinting. As a 1B tyre the AD08R is unlikely to be anywhere near as good as Supersoft Kumho V70a or Avon ZZR but I am pretty sure a few class 1 and 2 runners use the AD08. For road use I am sure the AD08R would be fine and certainly better than many alternatives.

It was a great day despite starting out wet and drizzly. The final runs were on a virtually dry surface but it wasn't going to be a record beating day. my 46.14s T4. Gill had a grin from ear to ear when she collected her trophy for 2nd in class 😬.

It's a few years old but in very good condition. It's equivalent to the current DL1 Sport but has an Ali/Carbon case rather than the current ABS version. Included is a magnetic GPS antenna, a cigarette lighter power supply, a CF card, a pair of mounting brackets and a serial (null modem) cable. The analysis software is freely downloaded from their site. £250 I also have an Emerald ECU interface cable which allows you to log all the Emerald parameters - £75 Both items together - £300

We used to get 6000 miles a year from super soft compound Kumho V70A including a full season of sprint/hillclimb dual driven. The road use had negligible impact. I have used soft compound R888 and they are not as good. My current setup means we don't get a whole season out of a set of Kumho but we do have 260bhp and an aggressive geometry setup. ZZR are popular in A24 compound but I've not tried them.

Lots of midge bites here too mostly from Friday night as we were able to use Chris B's nuclear midge deterrent on Saturday Also managed to scratch my eye with some grit at some point on Sunday Still a great weekend though.

On my P2 it is 35.56s with about 1/10 diff between Racekeeper time and recorded time (55.45 RK vs 55.33 recorded) On my T1 it is 35.46s also with about 1/10 diff between Racekeeper time and recorded time (55.68 RK vs 55.57 recorded). Not sure what conclusions to draw from that. I'm setting the start point as soon as I can see the car move on the video but I guess it might not break the timing beam immediately.

Simon - that post will never walk again
-
P2 - 57.33s.
-
My T1 . I made mistakes at both chicanes which cost me - the run was a tiny bit quicker than my P2 up to the first chicane according to the data. I'll upload the quicker P2 tomorrow.
-
Having done a 55.33 in practice it seems possible to get into the 54s without a Busa engine 😬. 113mph before braking for the final hairpin and that was braking too early I will upload my video tonight.

That's the common set-up for class 4, 5 and 6 in the L7C sprint championship. These are 190bhp + cars (class 4), unlimited in class 5 and mostly Hayabusa in 6 so all pretty powerful. The fat fronts appear to provide better braking although there isn't lots of evidence. In a high power car on track they are certainly not over tyred but it depends what you want out of your car - ultimate grip or a car that moves around more. I run this set-up for sprint/hillclimb, road and track and just have a harder compound set for track. My car has a 260bhp Duratec.

Do you really need twin cables? In the UK racing world the requirement is for independent closing mechanism - i.e. each throttle needs it's own closing spring - most set-ups have that as standard. I assume this is on twin Webers? Each carb has it's own closing spring normally. The cable doesn't close the throttle - the spring does - so twin cables don't offer any advantage in a stuck throttle situation which is normally what the rules are trying to prevent. If there is some other weird rule in NZ 😬 then just ignore me.

is what happens when you get a red flag (thanks David ) at the top of Gurston. I crossed the finish line at a heady 2mph
-
I'll post what happens when you get a red flag just before the finish line a bit later.

It was me out bedding my new brake discs in before Gurston Down hillclimb this weekend. I managed to dodge the showers and the new discs seem to work OK. Not the smoothest of test routes but better than going out the other way towards Mortimer

Hi Stu - a few of us are competing in the BMMC sprint on Saturday and then the Club event is on the Sunday. On Saturday, practice runs start at 9:15 and it is possible first timed runs will be before lunch, in which case there would normally be at least 2 timed runs in the afternoon. On Sunday, practice runs start at 9:00 and it is also possible first timed runs will be before lunch, in which case there would normally be at least 2 timed runs in the afternoon. Entry is free.

I've got some short injectors on mine (the blue ones on the left half way down this page) as the Bosch green fouled the filter backplate. They barely fit in the throttle bodies but haven't caused any problem. If you are using the Jenvey fuel rail then Jenvey can supply some small plastic spacers which help locate them.
-
We'll be there Friday and Saturday nights. There is a shower and a clubhouse serving food and beer.
-
Try moving the sensor closer to the bolts. If that doesn't fix it you probably need a new sensor. You can get them half the price that Stack charge - search techtalk for the supplier and part number or drop me a line and I'll dig it out for you.
