Before getting going on the IVA prep I needed to fit the revised engine mounts. The BDN uses a sort of modular system to allow any engine to be fitted using the same basic mount sbut with different machined adapter bobbins to accommodate the different engine widths. Ian and Brian think the bobbins allow too much flex once the engine’s under full power causing the reverse gear to impinge on the starter motor so Ian’s redesigned them with pair of beefy machined parts. The lower part braces the mount back to the rear bulkhead and unfortunately needed a bit of modification as it didn’t quite fit – probably because I’d needed to move the mounting hole when I originally fitted the engine. Here it is fitted to the engine mount plate ready for refitting.
The upper part looked like it was going to be a drop in fit but needed a couple of extra 10mm holes drilling in the mount plates. Once I’d done that I had to file quite a bit off it as the engine mounting lugs slope backwards rather than being vertical. Here it is once I’d sorted that and got it bolted in. It certainly looks like it should keep the mount plates nice and square.
I had limited time at the weekend but did make a start on getting the car ready for IVA. The initial stages of this mostly comprised taking things off it. I started with the rain light and the video camera then took the fire extinguisher out. I left the plumbing for this in, I’ll make sure the extinguisher end is secured and taped up and I removed the cockpit nozzle which was on a little ali bracket under the dash. I then removed the brake bias adjuster and it’s bracket then moved onto the cockpit adjustable ARB – I suspect this would actually be OK but I don’t want to leave anything on that might cause an issue especially when it’s not a terribly difficult job to take it off. I tapped a long 6mm screw to replace it so I still have an adjustable ARB, just not from the driver’s seat.
On Monday the nice man from VOSA rang me to get my credit card details to charge me the £450 for the IVA. I later had an email asking me for receipts and photos to confirm that it was an amateur build by myself. It didn’t take too long to produce copies of receipts for all the major bits and I printed off a selection of my vast collection of photos. Since the VOSA main office is only about half a mile from the surgery I dropped them in at lunchtime on Tuesday.
While working on the car on Sunday I realised the garage had reached the point where it was a hazard! I was having to step over stuff wherever I went so I decided before I carried on I needed to have a tidy up. I hadn’t actually seen the bench for a good couple of months for all the clutter on it so that was the first focus of attention.
After some email correspondence with Dan Bromilow, a fellow RGB racer who SVA’d his race Fury, I decided to stick with my plan A on the harness front which was to use the cheap ‘E’ marked harnesses I got from Car builder Solutions. These need normal bolts rather than eyebolts and our local emporium didn’t stock tensile 7/16″ UNF bolts so I ordered some from Namrick. Having cleared the bench I also turned a set of 10mm spacers as the harness eyes are cranked and need spacing out from the mounting points.
The handbrake was next on the list. It works great but at present there’s no compensator mechanism to balance the two sides and the IVA manual states “The parking brake mechanism must incorporate a means of compensation between all brake assemblies operated by the parking brake control, and a means of adjustment to compensate for wear.”. On ‘normal’ cables this is usually done by using a single cable with a semicircular part that allows the cable to slide around it. Having given it some thought over the months I did have a cunning plan involving a pivoting bar connected to the lever via a rod and a small rose joint.
I’d posted the original reverse gear back to Brian on Saturday and the shiny new one arrived back on Wednesday. Brian’s pretty busy at the moment getting his son Rob’s car sorted and I know Rob’s over from Australia at the moment so I wasn’t expecting such a quick turnaround. This didn’t take long to fit then I refitted the rear sprocket and got the chain tensioned.
Friday’s goal was to get the handbrake sorted out along with anything else I could fit into the day. As these things usually pan out it took far longer than I’d anticipated but by late afternoon I’d fabricated new bracketry and got it painted and hung up to dry. Once fitted I was very happy with it, the previous bracketry had a bit of give in it while this is braced much better and is more effective. Lots of folks have trouble getting Wilwood handbrakes through IVA, at least I have the advantage that the pads/disks are well bedded in.
The VOSA inspector rang me around lunchtime to book my test appointment. Unfortunately he was booked up for the following week and was off on hols the week after so it’s booked in the first week of August. I initially booked the Wednesday but rang him back and changed to the Friday – we’re racing at Snetterton the weekend before and I probably won’t be home till late Sunday night which wouldn’t leave much time to prep the car. Also if anything were to happen to the car and I had to cancel you lose the fee if it’s less than 3 days notice.
So this means I’ll need to refit some of the bits I took off. There are still plenty of things I can sort though.
On Saturday I got the headlight adjustment sorted. With them just bolted on they’re pointing just a tad lower than they need to be so I needed some way of being able to adjust them upwards. I came up with a plan involving sticking a couple of rivnuts just below the mounting holes with 5mm screws through them from the back so that when screwed in they push the bottom of the light unit up. This worked nicely and will allow adjustment with the covers still on. You can see the lower adjusting screws with their locknuts in this photo.
I didn’t get much done on Sunday as management had other plans for me. I made a start on refitting the stuff for Snetterton and got the rain light and camera refitted. I’ll concentrate this week on getting the car ready for Snett then try to get some of the other IVA stuff done that won’t need to come off for racing like wiring pup the hazards, making a new passenger seat etc.
