SBD Westfield – 1.6L EcoBoost
The 1.6L EcoBoost SBD Westfield is being driven by a few drivers depending on the event, they include Steve, Matt, Carole and Zoe.
June 2021 – Pembrey
Zoe, who had been competing quite happily on her own on Saturday in the SBD 1.6L EcoBoost Westfield, then found she had a co-driver – Steve! She had been gradually getting faster over the day despite the changeable conditions, also qualifying for both BSC run offs. On Sunday, we were competing on the Clubmans Circuit and the weather was sunny with a few clouds.
Zoe was going out first for the runs and once again gradually improving her times. Although Steve had to re-adjust to driving a Westfield again and having no downforce, to carry him round the corners, he felt that the car wasn’t handling very well. He made some small changes to the set up during the day in an effort to improve the handling. Both competed in the 1st Top 12 run off, however because the temperature of the tyres is very different for the first and second driver, for the 3rd timed run, it was agreed that Steve would go out first to feel the difference. Off the start line he was going well even if it was a little lively at the rear, unfortunately the rear stepped out just on the entry to Woodlands and Steve had to make a small correction which forced the car slightly wide, causing the car to head towards the edge of the circuit and touched the grass causing a spin, which launched the Westie into the air when it hit a bump in the grass, which ripped the floor off (it stayed in one piece!), he then spun another 360 degrees and stopped facing the wrong way but back on the track! And that was the end of the Westie’s day.
April 2021- Regis Sprint, Goodwood
The SBD Westfield had the new intercooler ducting and repositioned radiator, the air temperature and water temperatures considerably lower than last year, back down to levels we had never seen before. Probably need a little bit more work on the ducting, just to get the last bit out of it. Zoe was going well and her times were coming down, unfortunately a coil connection failed on her second timed run when going down the main straight. This slowed her down dramatically, we could see it was going to be a much quicker run. Unfortunately we didn’t have time to fix it for the third timed run.
With the culmination of all the testing we did in 2020, where it was discovered that the air was not physically getting to the intercooler and simply going over the top of it due to the shape of the nose cone. The Westfield was returned to Alicool, where the radiator was repositioned as low as possible, the intercooler was enlarged slightly due to the extra space we found. We refitted the original bonnet/nose cone and Keith at Alicool designed a completely new scoop to drawn straight from the front of the nose cone where the air would normally supply the radiator. This meant the 50% of the entry to the nose cone now supplies the air to the intercooler, we have opened up the splitter underneath the nose cone so air can entry through the splitter to the lower half of the radiator. We won’t know the results until the first event, hopefully at Goodwood on the 17th April.
Although this season has been very short, we have carried out a huge amount of testing on the intercooler and radiator on the 1.6L EcoBoost SBD Westfield, which was built for us by Alicool. The radiator has been extremely efficient and we haven’t been using it to its full potential. We have been struggling with intake temperatures and at the final event where we tested a major modification to the air intake to the intercooler, we finally proved that there was a lack of air flow going into the intercooler. So Steve & Keith at Alicool have devised a plan to relocate the radiator and intercooler then change the way the air enters them both. The air flow will then be provided from the same source for both, the design will also allow us to make the front end of the Westfield effectively look standard again, the currently secret design will be revealed once finished!
We could tell from the data, that the intercooler wasn’t working properly on the Westfield at Castle Combe. We were guessing that it was a problem with the ducting because there is a similar version functioning correctly on another car, so we forwarded the data on to Keith at Alicool and he confirmed that he could see the intercooler working efficiently under certain conditions but not at speed, so this confirmed that the air is not being forced into the intercooler so we have initially modified the entry ducting ready for Goodwood. We may also need to improve the engine bay circulation because it is as equally important, if not more so that there is low pressure behind the intercooler to draw the air through it.
The 1.6L EcoBoost engine was upgraded over the winter with more horsepower, up to 376bhp and 341lbft
The Westfield went to Alicool over the 2019/2020 winter to have a new cooling system designed.
Goodwood, 11th May
Steve: 3rd Overall, 1st in Class – 84.38s
Zoe: 2nd in Class, Fastest Lady – 88.74s
Steve’s first go in the Westfield for about a year, the car feels much smoother with all the updates with a better feel with the new Pirelli tyres fitted. It was a cool start to the day and he had to dial himself back into a different style of driving from the SBD Dallara. The car was already quick being fastest in class after practice, as the day warmed up and Steve got more comfortable in the car, he made small adjustments to the settings. The car was quicker again on each run, although it wasn’t until the final run when the temperatures had warmed and Steve was beginning to remember how to drive a Westfield, that he really got comfortable in the car. We will be making a few adjustments to the car before Blyton, so it should be quicker again for Zoe and Chris Jones.
Zoe’s quote after her first time competing at Goodwood : ‘Only went and came 2nd in class (Steve was 1st) AND fastest lady of the day at Goodwood today
Timed run 1: 95.56
Timed run 2: 95.12
Timed run 3: 88.74
Already looking forward to Blyton this coming weekend’
Castle Combe 23 March Chris Jones was sharing our Westfield, he qualified for the Top 12, achieving a new BSC Class Record – 128.78s YouTube Video
Snetterton 23/24 June
The SBD 1.6L EcoBoost Westfield had a good Saturday at Snetterton with Matt winning class in 93.32s and Zoe improving her time by 13s to 104.44s. On Sunday, we were testing some different boost settings, we are still struggling to get the power down on to the track, which is causing a few handling issues at the moment, so we had to revert back to reduced boost. Unfortunately a boost pipe blew off, but it was repaired in the paddock.
This was the first time Steve had driven the SBD 1.6L EcoBoost Westfield since a few laps at Llandow, we had changed the spring rate significantly on the rear of the car but hadn’t had time to cornerweight it. Justyn Potter from Aurok agreed to come along to Abingdon. The car was lacking in grip for the first few runs but slowly adjustments were made to the settings including the brake bias and the car got improved. It wasn’t actually until the final run of the day that we started to get very comfortable & were able to put a lot more of the power down. Steve won the class, Zoe improved again throughout the day and got within of 10 seconds of Steve’s time on Abingdon course.
The SBD 1.6L EcoBoost Westfield ran faultlessy all weekend, with Matt winning class both days. Zoe enjoyed her first event & improved her time over the weekend by 31.26s! We are continuing to improve the suspension settings so the power can be put to the ground, the next event is at Abingdon on Saturday where the car will be shared by Steve & Zoe.
We had a successful day at Llandow testing the SBD 1.6L EcoBoost Westfield. Steve, Matt, Carole, Craig and our newest driver Zoe all went out on track to put it though its paces. The Westie will be out at Pembrey Summer Sprint with Zoe driving both days and sharing with either Steve or Matt, who are also driving the SBD XE Dallara. So a busy weekend is forecast!
The SBD Westfield went to Simon at Sileck Motorsport Wiring to have the full chassis harness finished and 1st time fire up, our thanks to Simon who worked all of Saturday and into Sunday to finish it.
Steve has spent many days over the last 2 years at DTW Engines, running the 1.6L EcoBoost engine on the dyno to test the turbos developed by Turbo Technics and to fine tune the mapping and strategies in the MBE9A6 DI ECU. The first production turbo for the 1.6L EcoBoost 350bhp spec kit has now been fitted to the Westfield. You can see the ceramic coating, which is an optional extra. In testing we have found the ceramic coating helps to heat up quicker and retain heat, this means that boost is achieve sooner due to the fact that the turbo is up to temperature.
Our 1.6L EcoBoost engine developments were featured in the HSA’s magazine Speedscene, who have given us permission to reproduce it on our website.
Steve built up the gearbox actuator assembly and mounted it on to our Sadev gearbox, he has fitted a larger than normal actuator due to the high force required to operate the Sadev gearbox. It was then mounted into the chassis of the SBD Westfield and coupled up to our 1.6L EcoBoost. It is a nice compact unit and fitting the ancillaries continued to further progress the build.
Steve has been working hard over the weekend with Matt and Colin installing the first production EcoBoost dry sump system and bellhousing in to our SBD Westfield. The production version fits beautifully and the dry sump kit and bellhousing match together with engine making for an incredibly strong installation. The bellhousing is designed with a Ford pattern to mate to the gearbox, we are using Sadev box but could be connected to Quaife or Tractive type boxes however it needs to be a strong gearbox to cope with the torque of the EcoBoost.
The engine was due to be run on the dyno in the next few weeks, to run initially in standard form and then with a redesigned turbo being developed by Turbo Technics for us. MBE have produced a motorsport version of their production car EcoBoost ECU especially for us.
We began building a new Westfield which was to be powered by the 1.6L EcoBoost engine, progress as you can tell was slow due to work load.
