The day had come at last to give the car it's first run. It was an early start having loaded the car on the trailer on the night before. It was a wet drive to Silverstone which did not fill me with confidence. It was a Lotus on Track organised day on the full GP circuit and we arrived 30 mins. before the driver's briefing giving me chance to unload the car and get set up in the garage. Andy Napier got there earlier and saved me a space in the garage. Good lad!
Took the day off on the friday to get the last few little jobs done and check everything over (again!). The main job was to pipe-up the fire extinguisher. I didn't need it for the track day as road car regs apply but I wanted it working... just in case!
First the extinguisher cradle had to be bolted down. The only place for it is in the passenger footwell. 4 x 6mm holes with the air drill and it was fixed in place. I had already wired up the internal and external pushbuttons and fixed the control box when I carried out the work re-wiring the dash panel. So all that I had to do when I was ready was plug the connector into the extinguisher firing control unit when I was ready. The lifeline system comes with all the hose fittings that are needed. The regs. require 2 nozzles in the cabin and 2 to 4 in the engine bay pointing at the bits that burn i.e. the fuel and the oil systems. I didn't want lots of plumbing around the clam as this meant I would have to disconnect it whenever I wanted to remove the clam. So I went for 2 nozzles mounted in the bulkhead behind the seats, one pointing down each side of the engine. Once these were bolted up, it was then the tricky task of cutting and bending the plastic coated aluminium tube so that the two bulkhead nozzles could be tee'd together and a single tube shaped to go from the bulkhead pax side along the floor near the pax sill, across the floor in front of the pax seat and then into the push fitting tee of the extinguisher firing unit. The other end of the tee connects the two nozzles that I had set up facing up into the driver and passenger sides from the centre tunnel. These really needed a proper support bracket to fix them but were fixed temporarily for the track day using duck tape as the job had taken a lot longer than I had thought. Another job for another day.
September 10 ....... the list of things to do gets smaller
Posted by MartinS at Wednesday, September 15, 2010The focus was now Silverstone on 16th October. That must be do-able! surely...
It was starting to look like a proper race car inside. A good weekend's work!!.
.... that was the plan anyway, 16 September at Oulton Park.
Jobs that had to be done that would take time were :-
- Remove, paint & refit front and rear clams, bonnet and boot lids, roof and wing mirrors.
- Full geo set up.
- Fit Tillet race seat, fit drivers 6 point Schroth race harness, pax seat and Schroth 4 point harness.
- Fit Lifeline electronic fire extinguisher, pipework and nozzles in cockpit and engine bay
- Fit TSL timing unit
- Fix faulty engine temp readout on stack dash
- Test and fix lighting system and sort out rear fog light not working
- Fit wheel arch liners
- Find and fit door seals and fit doors properly!
- Make and fit boot bulkhead
- Fit graphics and series stickers
............. then I had to get some circuit time to learn to drive the car !!
To make matters worse, work was really busy and becoming a real time and thought distraction. The pressure of getting all the jobs done in time for Oulton was making the task just impossible... so I made the decision to pull out of Oulton. That would give me plenty of time, almost a month, before the next round that I could do which was Silverstone National on 16 October.
.... that seemed much more do-able! So the email went off to Mr Golding to say that I was scratching from Oulton. To say I was disappointed is an understatement but I was at the same time relieved as the pressure was off for a bit.
Full Power test at TDI
The full results of the test are shown in the power curve and data sheet below:-
The last week has been pretty busy getting the car prepared to go over to Dave Walker at Emerald near Norwich for mapping the K6.
Jobs on the list were fitting motorsport quick release catches to the bonnet and boot. This involved removing the old catches and making up some aluminium brackets to mount the Q/R post to.
The boot cover needed a repaint from its original silver to satin black. Plenty of rubbing down and spraying later it was ready to go on. Similarly the doors that I had stripped down months ago had to be rubbed down, painted satin black and re-assembled and re-hung. All of this took up a whole weekend. I am a couple of window seals missing but those can be sourced over the next few weeks.
The new rear Sport 160 spoiler and raiser blocks had to be painted after first lining up and drillng the rear clam (scary!) and then a bright vivid red paint job. After 24 hours for the paint to harden it was fitted on the car.
The motorsport lightweight hardtop was next to go on after first fitting a new seal to the perspex rear window and making new retainers for the rollbar cover clips as they are not available new from Lotus. The hardtop is fixed with four bolts at the leading edge which involves drilling the windscreen surround (scary moment no.2!!). After drilling the hardtop first and marking the surround it was a careful job to drill the surround. It's about 50mm thick and needs to be at the right angle to bolt up squarely. Having checked the bolts would go in, tiger seal went on the roll bar cover which would secure the hardtop at the rear. Job was quite straightforward in the end.
Next job was to fabricate a heatshield between the exhaust manifold from the large piece of nimbus I had bought from Yvo at Elise Shop as part of the SELOC group buy. I started by making a template from card. I wanted it to wrap around the manifold protecting the bulkhead, laminova and oil pipes and go down to to the undertray so that all the heat would be funnelled up and through the boot cover vents. Took a while and while I was at it I fabricated a small piece that would protect the oil filter which becomes pretty close to the manifold when the oil cooler take off adapter is fitted. I took the opportunity to fit the alternator heatshield from Eliseparts. It comes flatpacked and takes a while to work out where it bends and folds, but I got there in the end. It looks really good now it's finished and works very well.
I had originally intended not to fit wheel arch liners but changed my mind. I had 2 rears already and just needed a pair of fronts which I picked up from SELOC classifieds.
On the big day (today) I had to fit the liners, quickly set front and rear toe by eye and bleed the brakes once more just to be sure. I was due at Emerald at 2pm and started the jobs at 7am. I checked all the fluids once more plus tyre pressures and torque up the wheelnuts. I had only ever started the engine in the garage and reversed it in and out a few times but never run it up through the gears and bedded the brakes. Wasn't too worried about them as they would not be needed today. So at 10.30 i reversed the car out and onto the road and ran it up and down my quiet rural road just to make sure I could get gears and all was ok. Took a few pics for posterity....
Finally I was ready and after a quick check of the preparation notes for mapping from Emerald, I had a last check of oil and water before setting off. A quick txt to Andy Napier to check what fuel was best and I was off to Watton in Norfolk. Andy had recommended Shall Super V but there were only BP stations on route so I had to go for BP super unleaded. The elise was filled right up and a jerry can also filled for good measure. Dave recommends bringing plenty of fuel as cars can use a fair bit on the dyno.
Watton is about an hour and 15 away for me. I was made welcome by Dave and the team and they quickly set about checking the car over and strapping it down on the rollers. The dyno is in a sound proof room and fitted out with plenty of air blowers that were positioned at the front of the car for cooling and blowing air in and around the engine bay. There is also a meaty exhaust and fume extraction setup as you would expect. Dave prefers it if the undertrays are removed which was handy cos they had not been fitted (one less job for me in getting the car ready!). Dave hooked up his test bay PC to the serial comms port and positioned the twin lcd screens he uses during the mapping so that he can easily read them when he is sat in the car at the controls.
The screen on the right had the standard M3D software running and the screen on the left is dedicated to various instrument and dyno live readings.This screen can also display graphs of results after each mapping run. Dave has a wireless keyboard and settings console for use inside the car whilst he is at the car controls.
The mapping process consists of adjusting and setting ignition and fuelling for each of the 16 load sites in the M3D ecu at increasing revs. A wide band lambda probe is put in the car to get AFR readings.
Dave was happy for me to sit in on the session provided I used the ear defenders provided. It was all pretty relaxed at first as he set about mapping at low revs. I was a bit nervous generally as the car had never been properly run apart from a few engine starts in the garage and a couple of hundred yards of running up and down the road at home just to check that I could get all five gears on the new box and linkage. Mapping is laways carried out by Dave using fourth gear runs.
I started to get more nervous when the revs got a bit higher! Once you get to about 5000 rpm it's all very noisy and the car is really straining at the restraint straps. During the full power runs towards the end at 7000 rpm maximum revs I hav to admit to having my fingers crossed.I needn't have worried as the car ran faultlessly with no leaks and the temps stayed rock steady which showed that the PRRT and laminova were doing their job.
After about 2 hours the mapping was finished and I nervously waited for the final figures. The scores on the doors were max power 163 bhp @ 6,800 rpm at the flywheel with a smooth curve and no flat spots and max 142 torques @ 4,900 rpm with a nice healthy flat 135 torques between 4250 and 6000 rpm. Dave reckons that equates to about 143 bhp at the hubs but the official ET power test I have booked for Friday 13th August at TDI will confirm. I have to admit to being a bit disappointed as I thought I might see 170 bhp peak and maybe 146/7 at the hubs but better to be sure of being within the 151 bhp limit for the series. Dave reckons that the power is about right for the engine spec and I have to believe he is right. One potential future bonus may come from using better fuel. Dave was not impressed with the fuel I had used and recommended the Shell Super V which might be worth another 1 or 2 bhp on top.
Power Curve
Next blog update will be after the TDI power test when I will post up the official power curve.
30 July 10 ...... Installing the Emerald K6 and bleeding brakes!
Posted by MartinS at Friday, July 30, 2010No pics I'm afraid in this blog update as I am working so quickly there is just not time.
Finally my new Emerald K6 arrived. Lots of apologies from Karl at Emerald but he wanted to make sure that the base VVC map was a good one and had been testing it on a hack at Emerald HQ for a good while. I had set aside a saturday morning to do the pin movements. The Emerald ecu has only one 36-pin male euroconnector and the std. VVC MEMS loom has 2 female 36-pin euroconnectors coloured black and red). The idea is that the removable pins are moved from the two existing plugs to a new single one provided in the K6 kit. This takes some concentration but after a couple of hours I had swapped everything and checked it thoroughly over a second time. Software from Emerald supplied CD was loaded onto my IBM Thinkpad laptop, RS232 serial lead was connected to the appropriate port on the K6 and that;s where it stopped. Turns out the usb connectivity firmware is not yet sorted on the K6 even though it has a usb port and guess what my laptop doesn't have an RS232 serial port. To that matter neither did my works laptop so I was buggered! A quick email to Emerald on the Monday produced a very nice EasySync usb to RS232 adapter which with software loaded worked a peach.
I did find the next day that the coolant had dropped and there was a hint of coolant under the o/s rear sill which turned out to be a hose clip that had 'relaxed'. Annoyingly this did involve removing the petrol tank shear plate to check that the leak wasn't on the coolant pipework in the sills.
Bringing things bang up to date, earlier this week attention turned to bleeding the brakes and clutch. I had put new seal kits in both front and rear calipers and new stainless aeroquip brake lines. Quick check that unions and hoses were tight and a fill of the reservoir with Motul RBF600 and on with the Eazibleed. Brake fluid pi**ed out of the rear calipers depositing most of the (expensive) Motul on my drive. Retired hurt that night!
Next night rear calipers came off and were stripped. Turns out after consulting the SELOC masssive yet again that there were some bits missing from the calipers I had bought used (cheers Junks lol...). To be fair he didn't realise! So I took the bits I needed from the original calipers which were the threaded bits that fit inside the piston and wind the piston out as part of the handbrake auto adjust mechanism. These in itself were not directly what caused the fluid to leak but the seal that was part of the missing bits is what stops the fluid leaking out of the top of the piston and through the dust seals. With the right bits fitted the clutch and brakes were bled through using the Eazibleed. Couldn't get anything on the brake pedal at first and had to have a second go using the inverting and tapping the front caliper method. Got a good pedal at one stage but lost it again so there must be some air still in there somewhere.
Got the whole weekend to work on the car this weekend as Em is away on a hen weekend so makimng a start on fettling the bodywork and getting it looking like a race car. Another update and some piccies soon.........
......the last blog post so apologies for that! It is because I have been spending so much time on the car honest!.
Just a short post to report on progress over the last week or so. Really want to get the car down on it's wheels so that I can get the suspension all torqued up and see how the suspension and steering alignment looks to be about right by eye before a full geo. Not having the springs for the single way nitrons I had off junks that came with the donor car has delayed getting this done. Finally they arrived and mighty fine they looked in the box. I went for 450F/550R ratings with 150lb helpers based on a poll of drivers that I had asked at rounds earlier this year.
Wasn't too difficult a job to mount them on the bodies once I had worked out how to remove (and set up again afterwards) the removeable end fitting that contains the rebound adjuster. Obviously the pre-load has to be guessed at this stage and subsequent ride height set when the units are on the car and it is down on it's wheels.
Next job was to get them onto the car which was straightforward enough except that I had forgotten that it is easier to adjust ride height if the units are fitted upside down. Of course, you guessed it, the helpers were at the bottom which is not good practice and even worse, the writing that said nitrons and spring rating were upside down - disaster!. For those of you that know me, you know I have to have it right!!
With both rears on it was time to stand back and refelect on the fact that I am getting there............
15 Apr 10 ..... Fitting Clutch, Gearbox and Installing the Engine
Posted by MartinS at Saturday, May 15, 2010
24 Apr 10 ..... Front brakes, engine build, dash assembly and body
Posted by MartinS at Monday, April 26, 2010When I last updated progress on the VVC it was to strip it down to the block and head, degrease and inspect for damage/wear. The VVC is the EU2 version and as it came from a low mileage 'S' I have decided to put it in and run it rather than stripping it right down and rebuilding with new internals. So mostly the jobs were to clean up and do a visual check for obvious problems and compiling a list of missing parts. Some of the bits can come off the original K16 that was in the project donor car like the oil filter carrier, dipstick assembly, crankshaft main pulley, rigid cooling pipes and thermostat housing and various bolts/fixings.
One of the main items missing was the timing belt front and rear covers. I have spare K16 covers which I was able to adapt but will need to get a new front cover at least. They are still available and less than a tenner. The water and oil pumps were removed, cleaned and inspected. Both looked fine and were refitted with new gaskets. A new manual cambelt tensioner was fitted. The thermostat hosing was stripped, cleaned and the old stat removed and eliseparts blank stat and new 'o' rings fitted that came with the PRRT kit. The fuel injectors and fuel rail were cleaned and refitted together with the inlet manifold and VVC plenum, again with new gaskets. On the exhaust side, new studs were fitted and stud locked and the new Janspeed big bore 4-2-1 manifold trial fitted. The beauty of having the engine stand is that all the ancillaries can be fitted properly with good access. There are still a few things left to do before the engine can go back in like fitting the injector and main engine loom and making guarding for the alternator and oil filter from the large G3 nimbus sheet courtesy of Yvo at elise shop. Picked up a new 52mm throttle body and cambelt pulley off ebaywhich will be fitted during the next week when they arrived. I have ordered a sump baffle kit from eliseparts which will also be fitted in the coming week.
