I'm sure Clive will post up his usual report, but a few comments and photos from me whilst he's driving home.

After qualifying 7th on the grid, Clive had already climbed to 3rd place in the first race after less than half a lap. There was then an exciting, close race for 3rd/4th/5th place developing when, on the 3rd or 4th lap, Clive was shunted from the rear on braking for Agostini, ending his first race. Amazingly, on examining the car, it seemed there was no really serious damage, so Clive decided to continue into the 2nd race, starting from near the back of the grid (23rd of 26th place). He was climbing steadily through the field, up to 12th place after the first lap, before some issue must have occurred and retired  :-[

Not a good day for Clive - the positive note being the car was running really well until the shunt.

Some photos on Flickr here:

A few of from the collection:







Just after Tony Hunter, in the white Renault Clio 2000, had run into the back of Clive (see the deranged bodywork  :()

 
The impact sent Clive's car into a spin:

Beat me to it Jon  ;)

Suffice to say the reaction was more shock than anger as this was a guy I had raced many times and had respect for that he would not do anything stupid. You will see from the pictures below that, as I told him " he was overdriving the car" and he should have know better!

You will see my disgust with him as we entered the pits when he received two NASCAR style bumps from me which I planned so the marshals would not see, however I was staggered about the amount of people who did see and came up to me to say, yep he deserved that.
(even his wife tore him off a strip)

As Malcolm knows I called him over and sorted things out ending with a, that's the end of that and we move on. Malcolm came up to Race Control with me and all the clerk of the course wanted to know from me was if I wanted to take things further.
Had I had done this he probably would have had his licence revoked, which would have given me no satisfaction.

This is a enough for now, but tomorrow I will put a post up explaining what I have decided for the future and issues with the car post crash.         

All the best Clive

Tony got frustrated that I let him go twice going into Murrays knowing I could get him back, you will see the first time he overshot carrying two much speed and then going off, then next time round I just planned it so I came up under him leading on to the straight.

I'm sure this led to the attempt at a BTCC two wheel on the grass with locked up wheels at Agostini , Tony told me he was all locked up but as I said, I didn't shut the door and he knew I would brake earlier than him due to the weight of the RX-8     
All the best Clive

Started to review last weekends damage/ issues;

My biggest concern was that the engine would not run after being hit so I at least knew that the shock of the impact had dislodged something.
Checked the  connections on the pumps and the only thing found was what appears to be a dislodged pump fuse and as you will see on the pic below, that's never going to happen again!  Just hope that was the fault but if it runs a long time on the Dyno then I know its cured.

Shame is, I  would have still had a decent result had the engine worked after being hit!!

Stripped the rear bumper off for repair/ paint but the front of the rear wheel arch will take far more work.

The impact onto the exhaust meant the shock travelled though the system and broke the turbo  :(

On Monday I decided that I need to get myself out of the situation of  keep running with these other four cars if possible, so I have one of two options to stop fighting with these guys every race, go slower or go faster. Takes no working out which option I want to go for  ::)

I know the car has lacked initial acceleration due to Turbo lag and that the boost bleeds off when on the straights, which while safe, pulls power out of the engine.

So I am going to use a different Turbo configuration and dump the Garrett GT40 and go for a different Turbo  set up.

Working with AET turbo's and Pip at WGT, who has spent a lot of time overlaying  my map against other maps to work out between us what Turbo I need to get the car performing better :13: 

Outcome is that  I am having a custom Borg Warner SX300 turbo built, then plumb the wastegate directly into the Adaptronic ECU to let Pip control the duration of the wastegate, which will hopefully give me much more power low down giving better initial acceleration taking me out of the clutches of these smaller lighter cars (hopefully).

I also still cant get the car to turn in how I need it to so after talking to Tein, I will up the spring poundage on the back.

Hopefully next week I can look at bolting the new Turbo then up to Pip at WGT to get the mapping sorted.

Deadline is five weeks to Donnington when the car "should" look back to its old self and be faster as its new self

Here you go, Race 2 with commentary. Sorry for the delay in posting it everyone, it takes a bit of time editing these.

Hi Clive, see the piccy attached where you can see inside this type of fuse holder, is it possible 1 of fuse blades went down the side of crimp instead of init? you have a circuit but a poor connection.I did this when installing and it felt funny im wondering if been pulled since and not seated right, impact should not have affected it?? you have 2 of these coils and 044....thinking reliability changing for dash mounted Circuit breakers like Tonys got?

Hmmm, it is possible the blade went down the wrong side, but I don't think so, the fuse was very loose though, never going to come out now though.

My new MAC solenoid has arrived  so we should  have better waste gate control.

Just got to work out the plumbing to use the ECU in the system.
