G97 made it there, didn't break down or leak during the event and I managed 15 or 16 laps, tried both sets of wheels & tyres, changed the quick-shift gearstick back to standard, adjusted dampers to compensate for snap oversteer and played around with the fuel system to try and overcome the DCNF LH corner float problem.

So, additional jobs over the pre MOT and pre first event jobs are:

Buy and fit new 13" tyres (R888R are looking favourite)
Just seen these on eBay http://www.ebay.co.uk/itm/381600695453. Shipped from Italy, but around £40 a corner cheaper than here in the UK.

Although it would only cough on the first long left and hesitate coming out of the molehill, it would lose all power coming onto the straight uphill, so it may well be slightly low fuel pressure - I'll get a regulator and gauge on it before totally condemning them. I recall some mods were available but can't find anything online? Pretty sure I have everything for injection and I planned to go megajolt anyway - perhaps megasquirt is the way ahead (means I'll have to buy another one for 8 Ball though!)
Meant to reply to this ages ago. Thats where mine suffered hesitation, (it was fine at castle combe, a local event, and a very wet goodwood) but was Ok with R888s, only slicks + stiffer suspension caused it to occur. I dont think twin 40s will be happy with the fairly irregular and probably higher than needed pressure from most electric pumps. I have always run a regulator - currently a holley one set to 3.5psi IIRC. I cant remember if it was fuel starvation or over fueling (i.e. floats forced open, or floats forced shut). If its forced open, then a higher fuel pressure could be making it even worse. I'd give it a go with a regulator first.

Tried a regulator today and first impressions suggest it may have worked :-)

Couldn't get a sharp left handed turn at speed (no MOT) but donuts were the next best thing :mrgreen:

I had set it to public but apparently simply uploading it isn't enough, you have to "publish" it too :roll:

And YouTube even emailed me to ask if I wanted to publish it (but I hadn't checked my mail :oops:)

Forgot to download the other pics from yesterday - front ride height. Originally, we had this (300lb -15mm springs with flats on the end coils instead of the usual small sports type)

Image

First I tried the very short springs from Andy off the slammed SST but they were too short (and unknown poundage), so I could either use them with two rubber mounts or chop the ones I had. I took the flat coils off top and bottom and ended up with this:

Image
Which look okay with the 15" wheels on, need to test them on the 13s still.

The other springs are almost certainly 350s. They Will work provided you cut the bump stops out!

Best to stick with the 300s for now though i think.

Just a word of advice. Check carefully you shocks open and closed lengths when you change ride height. At one point my front shocks would "bottom" on tight bends , not good!

they were too low with only one rubber seat and the bump stops are already reduced in depth.

good point Nick - I checked them on the old setup so I think they'll be okay but I'll double check when I get my shocks back from Protech.
