Indeed, it was all very unfortunate - the car was performing beautifully so very frustrating that it had to end as it did. Still - we will bounce back as we always do.
If anyone has a spare yellow rear clam that would be great
The plan now is to split the clam and attach rear section of the clam to the chassis and hinge the front portion, in order to support the wing properly, which will allow us to run more downforce that we do currently.

hi Jonny
sorry been ill the last few days so couldnt post.
I met up with the guys on Saturday to see how everything was going. The team is a fantastic bunch of guys, very professional and the car looked fanastic.. The pace on friday was top class and being 3 seconds faster than everyone else such a reward to their hard efforts, unfortunately as you have all heard the 3 rd lap incident abit of a set back and very dissappointing.
Im sorry it didnt go well, but you will bounce back and with greater strength. The hard work will pay off and believe me there are some worried teams in the paddock, with their 200k-300k cars starting to see the back of the Ultima on track just like the days of Lee Noble in the 70's.
If there is anything i can do to help Jonny just ask. And thankyou for having time to have a good chat and allowing a close look at the car, much appreciated

Hi Dom,
No problem at all - just glad you had a good day despite the drama! Our pace was very good on Friday, particularly in the wet (as always), its just a shame that qualifying was the 'neither wet or dry' conditions which simply don't favour us at all.
Looking to get to the next round but it is going to be a push - seems to be no engine damage thankfully and the pinion shaft in the box is good, so just a bearing change and new rear casing in terms of the transmission. The rear clam could be the sticking point but will see.
Will update in due course. And another couple of shots to keep you entertained:

After 50 or so hours we have stripped the engine bay, cut out the offending spars and replaced them. The heavily damaged area included both verticals where the lower wishbones mount along with the gearbox and clam mounts. Both the verticals were cut out and entirely new bars put in place, with new lower wishbone mounting points manufactured.
The central lower cross brace was also cut out and replaced with a bar that goes straight across at the same level as the rest of the chassis - we don't run the standard LS7 sump anymore so it made sense to remove this - and we are getting the bellhousing machined so that it hangs down enough to protect the flywheel but does not protrude out the bottom of the chassis. A carbon fibre panel will be made to cover the opening under the ball housing.
Now that the underside of the car is all at the same level, we will have the option of running a flat floor right through which should give significant aero benefits. The bad news is that the flat floor we made to accomodate the lower cross member is no of no use!
Making progress!

Jonny: I was contemplating the change on the lowered cross bar the next time the engine is out could you post a picture of this mod with the motor back in the car? I assume that you run a A.R.E. dry sump pan which is what I have on my L.S. great product I also use the A.R.E. valve cover with the spray bar for the valve springs. That said one of the fellows here that is building a KILLER GTR has opted for the Dailey products pan with the pump mounted directly to the pan. Same pan as on the picture I showed earlier in this discussion. really nice piece of kit. Lee

We run a Dailey sump - the design is significantly better and the installation far neater than the ARE, and the reviews that we have had of both certainly swung us towards Dailey. Bill is very knowledgeable and helpful, despite how busy he clearly is.We move the bar forward slightly so that a rear end shunt would (hopefully) not result in the flywheel jamming on the bar and avoiding engine damage, as the flywheel hangs slightly below the sump (the pan is only 40mm or so deep). There is a slight cutout for the -10 oil inlet hose.
Not a great picture I am afraid...

Well done... sounds like its coming together for you and a leap forward too..
Can you let us all know the dates you are hoping to race this year?
Dom
It is slowly coming together. Hoping to make it out for the next round, which is August 9th at Snetterton. Following that it is Silverstone GP on September 20th - we may also do some GT Cup too.Can you let us all know the dates you are hoping to race this year?

Enjoy!
Guys that's a great piece of video. The car looks to be really well balanced, thanks for whatever filter you used to get rid of the obnoxious noise that was in one of your last videos. I still wonder about the wiper being so apparent in the drivers main view area. I know you have said that its just ignored but my 40 years of flying helicopters and studying lots of human factor stuff says it takes a toll on concentration. Just trying to contribute a thought, speed which comes in the form of concentration at the task at hand is a subtle mistress. Lee ............ i forgot to thank you for the picture it shows exactly what I wanted to see

Funnily enough we removed the wiper completely for this round - then inevitably it rained!Edited by ROWDYRENAULT on Wednesday 16th July 16:07
Not sure what we did differently on the video, but it is clear that we need a better microphone to pick up the base. Our early videos (from 2012) were taken on a series 2 GoPro which seems to have a much better microphone which picks up the base more effectively. This series 3 works well but the sound quality is very poor, which is a little disappointing.

Any way to connect another mike to better pick up the bass sound?
Regarding the wiper, it moves around like it had too much play in the mechanism. Not normal to me and as Lee says, it must be a source of distraction.
I think there is an external mic - will take a look at some point.Regarding the wiper, it moves around like it had too much play in the mechanism. Not normal to me and as Lee says, it must be a source of distraction.
The wiper is ****ed. Will swap it out for the next round - the splines on the wiper arm itself have given up.
Paddles are good - stripped the box to inspect for crash damage, and the dogs look brand new, so very pleased. Takes a significant amount of strain off the driver which makes a big difference.
So having repaired the chassis the next job was the bodywork - thankfully a very generous of our community, who shall remain nameless, offered us a clam that had been involved in a slight prang and needed some minor repairs - so we duly took the kind soul up on their offer and low and behold - we have a new(ish) rear clam! So a big thank you to the person who supplied this - without this there would have been next to zero chance of us racing in ten days time!
Sue to the complexity of the modifications to the rear clam, we decided to salvage the front half of the clam, cutoff the back portion and take the opportunity to solidly mount the rear section of the rear clam, complete with wing etc, onto the chassis. The new clam was dissected and the rear section was fitted onto a new frame which we built up - and boy is it solid. Can quite easily have two people stand on it without issue - this will enable us to run much more downforce than we could previously as we were limited by the clam mounting previously.
The front section of the rear clam was trimmed, tidied up and reinforced in a couple of places and hinged onto the rear section which was bolted onto the car - it works pretty well, just needs a bit of trimming at the front edge to make sure it open and closes cleanly.
So the 'major' work is done, now need to disassemble everything and rebuild the gearbox, which was put into place with no internals just to get everything aligned correctly, and a multitude of other small (but vital!) jobs like fill all the fluids, fit the rear light loom, do the tracking etc as well as tidying up all the edges and fits (not so vital!)...so there are going to be some late nights between now and the 8th August (next round at Snetterton) but hopefully should be OK...fingers crossed!
