Horiba D'Isis Stages Rally, April 2012

In preparation for the 2012 Horiba D'Isis Stage Rally at Mira we fitted the Lotusbits Lotus Sunbeam with a taller 4.778 differential to give a 120mph top speed and joined Simon Mauger on a test afternoon in Hemel Hemstead to try to set up the suspension. The test day was useful but unfortunately the alternator failed (short circuit) and killed the electrics which took most of the available 4 hours to fix.

Having had oil temperature issues on the past few events we redesigned the cooling pack at the front of the car fitting a huge oil cooler in front  of the radiator, positioning the air filter to the left where the oil cooler was previously located. We also made a cold air box around the air filter and put some holes in the bumper to increase airflow.

We scrutineered Friday night to have a more relaxing start on Saturday with no issues. Our co-driver for the event Jacqueline Jones travelled down from North Wales and joined us with her parents at scrutineering so we could sign on. We were getting a little worried when we had to travel through hailstones and snow getting to scrutineering.

We had Andrew and Ina make the trip from Baildon to Marshall and they were assigned junction 44.

On the Saturday morning we headed to service early and grabbed a nice big space for 4 cars, ourselves, fellow Wallasey MC Crew Dowthwaite and King, Howard in the Red Lotusbits Sunbeam and Nigel and Sam in the 205.

No issues in service and straight out to stage 1 on X12s tyres. Having heard all the hype about car 13 the 3Litre V6 450bhp Darrian of Fraser/Carter we carefully adjusted our mirror so we could get out of his way when he caught us. On stage it was difficult to hear Jacq on the intercom, probably down to the number of adapters required to connect a Stilo helmet to Terratrip.

On the long straights we were sat on the limiter in 5^th for what seemed like forever – even with the taller diff. The car felt floaty at the back at these speeds so we backed off the bump on the rear shocks to counteract  this during service.

The Darrian did not pass us and we found out why when he was dragged back to service with a very sorry looking back end…

Stage 2 was much better and 20 secs quicker. The shocks change stabilized the car at speed but reduced the low speed turn in so we softened the front dampers as well for SS3 as well as going to X08S tyres as the X12s were cooked.

On SS3 we caught and overtook the Stampers in their GC8 Subaru Impreza and kept an Aston Martin DB9 well behind us taking time out of him. Ian and Andrew were cursing us on Junction 44 as we kept wiping out the cones on the hairpin as the car was struggling to turn in.

 After SS3 we were surprised to find we were 9^th overall and ahead of one of the Metro 6R4s – Car 6 – going well!

On SS4 we had the bit between our teeth and  we were pressing on around the handling circuit and left the braking a little late for the level crossing and had a bit of a moment…

Later in the stage we managed to propel a bale across the stage with the rear wheel arch (got to keep the service crew busy to refit the wheel arch and mudflap)! A general spanner check did not find anything except a scratched sump guard.

Just prior to SS6 the heavens opened and soaked the circuit. We were caught on slicks so the stage was slippery and interesting to say the least. We had a long excursion over the grass half way round the first open 18 right which fortunately caused no damage and encouraged us to be a little more cautious.

After  SS6 we were joint 7^th with car 23, the Mark 2 Escort of Colin Chiles.

On SS7 the tarmac was drying but as the concrete roads were lethal in the wet we went out on worn X22 wet tyres – a wrong decision as the track was dry by the time we got out – this cost us 10 seconds – but we still took 3 seconds out of car 23 to secure 7^th place.

Back onto slick tyres for SS8 , the final stage -  we were under pressure to keep 7^th from Colin with the chance to steal 6^th from the 306 Maxi Kit Car of Guy Wigley. When we compared times at the end  of the stage Car 23 took 2 secs  out of us which left us in 7^th overall by 1 second!

Not a bad result with 3 Metro 6R4s, a Darrian and a 306 Maxi Kit car ahead of us….

Many to thanks to Kev Jones for his sound advice on suspension settings and tyre choice, and Jacqueline for guiding Lotusbits MD Mike Taylor around all day without any issues – although the service crew were a little worried after SS5 that they may have to fit a sick bag…

SMC Stages - Weeton Army Camp

SMC Stages, nr Blackpool -25th March 2012 
Mike Taylor and Samantha Bartlett

After a poor result at Anglesey on the Lee Holland stages due to the handling issues and a stage maximum, we were going over the Lotusbits Lotus Sunbeam to prepare it for the next rally at MIRA.

We received a phone call from the SMC stages entry secretary asking if would we like a late entry for Weeton on Sunday. It is not like us to enter an event at the last minute – we normally set the schedule at the beginning of the year… 

It sounded a good idea but the rally was only 3 days away – we needed a co-driver and service crew at very short notice. Service crew Sam was up for it as his car was not ready for Santa Pod “run what you brung” and Ben got a pass out from Carly. Sam (Samantha) was up for co-driving as she wanted more ANWCC championship points to stay ahead of Heather Stamper.  Game on!

We , thankfully, had an uneventful trip up the M6 arriving early.  We unloaded and were the 3^rd car in the queue for scrutineering – we needed to get through early as the Weeton Army Camp gates were closing at 4.30pm and we needed to leave the car and trailer there. Unfortunately the noise test official was late and the noise test was left until Sunday morning,  but the little Sunbeam passed scrutineering without a hitch.

We had an opportunity on arrival at Weeton to walk the course (with the permission of the chief marshal).  This allowed Sam to prepare her maps early to reduce the rush on Sunday morning , we headed off to the hotel for a few beers!

As we put a late entry in, we were running car #35. The organizers decided to drop us in between 3 and 4.

Various wheel arches on the Sunbeam had been “modified” by the scenery and driver during previous events, a regular occurrence. The service crew decided to run a wheelarch sweepstake,  each crew member naming an arch which they thought would be hit first!

Before the start we took the scrutineers advice and triple locked the harnesses around the roll cage bar. Off to the start only to be told off by the scrutineer as we had not removed the pin from the fire extinguishers!  

Stage 1 was very slippery and many of the bends were covered in gravel.  We caught and overtook car #3 on the first loop and car #10 on the second loop. We wandered over to the live results screen to find we were 5^th overall after stage 1 – it could have been worse especially as there were 2 World Rally Cars ahead, this was more like it, the Lotusbits Sunbeam beginning to work as it should.

The video camera recorded SS1, unfortunately without sound, so Ben limbered up and threaded himself into the back to rectify a duff connection from the intercom.

Car #3 retired on Stage 1 and unfortunately Car #1, an Escort WRC retired on SS2, it would have been nice to compare times with a modern 4 wheel drive World Rally Car, our Sunbeam now running the Lotusbits development traction control system.

At the end of SS3 the flying finish was immediately after a 90 left which we took a little too enthusiastically and ended up having to reverse to the time control, much to the amusement of the crew of Car #5 – LHD Escort Cosworth.

After SS3 the front tyres started to overheat so we went onto a pair of 8s and headed out for SS4 – perhaps something to do with the driver locking up and flat-spotting them, more enjoyable enthusiasm!

After SS4 we had moved up to 3^rd overall.  Following SS5 and a really bumpy stage, the crew checked over the suspension and found a split and bent front lower arm that needed changing.  Only 8 minutes between SS5 & SS6, not enough time, even for Ben and Sam. This was left until completion of SS6. As soon as we came in Ben and Sam set about the front corner, stripping out and replacing the bent arm – all done in 30 mins – a fantastic job by the Lotusbits spanner monkeys!  Note: more heat sleeves required as both Ben and Sam were branded by the glowing brake discs, that’s a determined service crew for you!

 Back out for SS7 the little Lotusbits Sunbeam remained 3^rd overall.

On SS7 the handling was not quite right and we went straight on at a junction collecting a cone and some tape – fortunately no damage. When we got back to service we found a couple of washers missing from the lower arm bush allowing the arm to push out the bushes letting the wheel flap around. Panic stations – we needed to get the inner mount off and replace the bushes properly – it sounds simple but not in 20 minutes.  2 minutes before we were due in to the time control we struggled to push the polybush back in. We ended up 6 mins late at the time control despite Sam and Bens best efforts. Fortunately there were no road penalties applied for this. The downside was starting right down the field behind several 1000cc Micras. On SS9 we overtook 3 cars on the stage including the Micra who began 30 secs in front – who kindly and  promptly let us through, although we lost a lot of time on the narrow nadgery bits where we could not overtake safely.

Car #14 retired on SS9 with a broken diff, after smashing a rim on SS8 which left us in 2^nd position overall.

 On SS10 we started behind Steve Johnson in the White F1000 Micra who, when we caught him indicated  for us to come through, which we lost no time in accepting only to overshoot the next junction going straight over the kerbs onto the grass! This allowed Steve back through in the process, we caught him again just before the flying finish… 

It felt like the tyres were going off so we put 2s on the front for SS11, but on the stage we had front grip but no rear grip. We had a spin in front of the heavily bandaged Manta losing 20 secs and dropping us down to 3^rd overall. When we checked the rear tyres in service we found that they had no tread left and had lost a layer of canvas as well! So a new pair of 2s on the rear and we took 25 secs out of our SS11 time.

We finished 3^rd overall – our best result yet!

Roll on Mira – The Lotusbits Sunbeam is currently with Willie Poole Motorsport Services on his jig, the front sump guard mounts need a tweak after the kerb adjusted  them slightly!

Lee Holland Memorial Stages, Anglesey

Lotusbits Talbot Sunbeam Lotus – Car 2 - Mike Taylor and Giles Dykes

Anglesey Circuit 18th March 2012

The previous weekend we were competing at Three Sisters in Wigan, which gave us a few issues to resolve. We had a strange misfire that appeared when we left service and disappeared when we went on stage, then fine when we came off, but re-appeared when we left service for the stage. Back in the workshop we removed the plugs and found one black one and 3 normal ones so suspected injectors. We had the injectors tested and found a 25% spread injector to injector – we obviously had a bad batch of PICO injectors – probably Chinese sh1t. We sourced a new set and took the car back to Northampton Motorsport and had it re-mapped – gained 10BHP!

Northampton Motorsport  were very helpful fitting us in the next day after a panicked phone call.

We also lost the Video camera at Three Sisters and changing the fuse did not help, so we investigated to find that the fuse descriptions were incorrect – new list made, laminated and fixed to the car.

All ready to load the car on the trailer and depart when half of the service crew (Bogbrush Ben) decides to disappear for an emergency hair cut without telling anyone delaying us for an hour.

Eventually on the road an hour late we are in convoy up the M6 when we smell rubber burning and pulled into the services – the auxiliary belt tensioner on the Transit tow van had seized. Luckily with the service crew and all our tools we were able to strip off the tensioner bearing and open it up to find it had lost half its balls, but with a bit of grease and TLC it was made to turn freely and refitted. When the tensioner was back on, we tried to put the belt on, but could not remember the correct routing- there are so many permutations it was unreal – thanks to Sam with his I Phone – Google provided the belt routing. Onwards to Wales...

We arrived at scrutineering two and a half hours later than planned, but were relieved to find there was still a queue of cars waiting. We found our co-driver Giles who was meeting us there and joined the queue.

Fortunately there were no issues with the car in scrutineering except some advice to re-route the harness rear belts around the roll cage to give a triple lock.

After scrutineering we checked into the hotel and headed to the bar and played the video footage from Three Sisters. We had noticed that the car under-steered badly on the Lunar bend on the event, but looking over the footage it was clear that the under-steer was more prevalent.

We had an eventful evening in the centre of Llangefni after Wales won the Grandslam and the town celebrated till the early hours until the fighting started and the police arrived to break it up.

We headed for the first stage in the morning with no further issues apart from a delayed start due to an accident on the A55 delaying all the marshals – more time for breakfast.

On SS1 it was immediately clear that we had a major issue with under-steer and the only way to get round the corners was very slow in. We only had 10 mins between SS1 &2 so no time to change anything. There were no results available till SS3 so we had to chat to the crews around us to find out where we were sitting We were a second behind car 3 and 2 seconds in front of car 4 so not so bad.

  On the longer break we changed the top arms on the front suspension to give 3 degrees negative camber instead of 2 degrees. This gave a minor improvement on SS3 but it still washed out leading to a spin over the top. The front dampers were fully soft on bump so we hardened the rear bump for SS4 – no gain. On SS5 we went to new tyres on the front – again no improvement.

On SS6 we put new tyres on the rear but part way into the stage we got a nasty vibration on cornering that progressed into a loss of power and constant vibration, so we decided to cut a loop and come in early as we thought the engine had let go. When we investigated in service we found a plug lead had come off as the leads had been cable tied together too tightly. On hind sight we should have stayed out and not taken a stage max which cost us 3 mins 40 secs dropping us down to 28^th overall.

As we were now out of contention for class and overall awards we decided to test different settings to cure the under-steer. We decided to harden the front shocks to where we ran the Micra last year which defied logic.

As we cut a loop we finished SS6 in front of Car 1 which meant we were first car on the road for SS7 & 8 – a new experience.

On SS7 the under-steer all but disappeared and we posted a 5^th overall time only 6 secs off car 1, and on SS8 took a further second off our time. We ended up 17^th overall, but gratifyingly for us, if the event was decided on the last 2 stages we would have been 4^th overall
