Mclaren Engine Advice

It has come to our attention that it is possible to cause engine damage to Mclaren cars if the car is run with low oil pressure or low oil level.

Now this may sound a bit ‘well, really’ but due to the potential consequences resulting from such action we feel it necessary to make owners aware of the risks.

Are of the engine where damage most commonly occurs.

In the event of running the engine at high rpm when cold or at any rpm with low oil the lack of lubrication is resulting in cam and cam follower damage. Mclaren do not supply engine parts separately so damage to these parts requires a new head, a minimum £4000 part up to £7000 for a 12c and the engine must be removed to effect the repair – 20 hours of labour so its not a minor fix.

Shows excess wear on cam and follower due to lack of lubrication

Our advice to owners is to always warm the car up fully before using higher rpm and to check their oil levels regularly, especially after a a service as its also come to our attention that some cars are being incorrectly serviced with inaccurate oil levels.

Area of the engine concerned

For details on how to check your oil level take a look at a short video here:

So, our advice to owners is always warm their cars up fully before any high rpm work and check your oil regularly, not exactly rocket science but certainly worth following.

MSV Track Day Championship Round 1

You never know what will happen with a new season and its fair to say that this one was a bit of a surprise.

Pre-season went well, the car has been heavily updated with new brakes, aero, less weight, new exhaust but the one thing we didnt touch was the power, plan was to run stock power and ballast to fit into the regulations for the Track Day Championship which we were entering for the first time this year.

New season, new grid

Pre-season testing went well, a day at Silverstone gave Callum the seat time he needed to get used to the upgrades and we were nice and confident for the first round at Donington Park. As with most championships that are based on power to weight there is an official dyno set to record the cars power which determines its class so the Friday before the race we took the car up to Donington for it to be tested. Well it came up with 215bhp – eeep.

Dyno tested on the Friday on the official series dyno

Now this was a bit of a surprise, we hadnt touched the mapping on the car since last season (no need to) and the pre-season testing went as expected so be told (by the official dyno for the series) that we are 80bhp down on what we would expect was a bit of a surprise, so we took the car back, put it on our dyno and the data was correct – 215bhp. So at Friday night before the race we had a bit of a dilemma, the car was low on power and no time to investigate so do we pull it or run the car in a lower class, so we put it in the lower class as the power was confirmed for the class so was legit.

Faultless drive on track

Well, they say power is only part of a race car and this was never more true, with the upgrades to brakes, weight and aero Callum drove a perfect race to collect his first win for the year. Comparing the laptimes to the other M3’s there it was clear he was hugely down on power so whilst the class was a bit of a surprise the result was well deserved and based on Callums driving.

First race, first win

The question now of course is what do we do, sort the power issue or run in the lower class with the lower power?

Either way was a great result from Callum, he didnt put a foot wrong in practice or the race so delighted to start the season with a trophy.

2019 Season BMW Racing

Well 2019 is with us and there has been a lot of changes to the BMW E36 M3 driven by Callum Noble.

Last year was a test year really to see how Callum adapted to the higher weight, power and grip of the E46 M3 chassis which bearing in mind he came from the 1125kg BMW E30 Production BMW series with a mere 145bhp was always going to be a leap. However Callum performed brilliantly and the season went pretty well with some good finishes but the car was a basic spec, relatively high weight (1320kg), standard power, only stage 1 brake upgrade, standard power and was really there to allow the transission from PBMW. Bigger plans were afoot for the 2019 season.

So over Winter the M3 has had its upgrades:

  • Weight reduction from 1320kg to 1250kg
  • Brake upgrade to AP5000 Race Kit front and rear
  • CSL Cup rear wing
  • CSL Cup front splitter
  • Rear diffuser
  • 3" bore race exhaust, decatted and single centre exit
  • Lexan windows

After a shakedown session at Silverstone we will have the first race in the Track Day Championship which starts at Donington Park on April 7th. We will of course keep everyone updated as to progress.

Here's to a successful season!

HydroFlow Engine Cleaning

Thorney Motorsport has been in the business of tuning cars for over 20 years and its fair to say we have seen our share of 'snake oil' products to emerge promising all kinds of performance gains. Oil additives, spurious petrol claims, engine flush treatments, pretty much all of them are there to expand the pocket of the garage rather than improve your car.

So when we are contacted by a company offering a process to clean your engine, gain power, improve fuel economy with no downsides and a cheap cost you can imagine our response......the second word was 'off'. However they persevered and the fact the guy selling it to us was previously employed by me for 5 years whom I respected I did begrudgingly agree to a demonstration.
So, we provided two cars to run the test on, our Mclaren 12c Spider, a £130,000 car which is already heavily modified but with low miles (20,000) so not exactly worn out and also our Citroen C2 race car, 118,000 mile shed which we are racing this year purely for fun. The reason we picked the Citroen is that the race regulations are very tight and we cant touch the engine all we can do in the regulations is clean it, so we figured thats what we'd do.
For the purposes of the test we dyno'd both cars and then ran the HydroFlow machine on each and then dyno'd the cars again, same day, same conditions.
Now the process of HydroFlow cleaning is quite dull, the machine uses distilled water to create pure hydrogen gas which we then feed into the cars air box intake (both intakes in the case of the Mclaren as its a V8) and then ran the car for 45 minutes, thats it. No special chemicals, no treatments, or tantric chanting, just feed a hose into the airbox intake of the car and let it idle, occasionally revving the engine a little to get the revs up. All that is used is pure hydrogen gas but what happens is that the hydrogen burns with the fuel at a higher temperature and the resulting extra localised heat cleans off the carbon build up in the valves, intake, exhaust, cats, DPF's  its a similar effect as a human body breathing in a Vicks vapour rub, its just opening up the airways that over time have become blocked.
Well if I said the results were amazing it would be an understatement. With the Mclaren I decided to road test it right after and the mid range pick up and acceleration was manifestly faster, and I do mean manifestly, it felt significantly faster. With the C2 race car we dyno'd it again and we had gained 10 bhp - thats 12% thats a dramatic increase for such a small engine (granted it had Moon miles on it) and a road test confirmed the engine revved up far smoother and quicker and it even felt faster, which for a gutless piece of crap race car the C2 is thats a statement.
However, despite all this we weren't convinced, it might have worked on a couple of cars but the equipment is a lot of money so I declined to buy it but seeing on how thorough we were on testing the suppliers offered to pay us to test a wider range of vehicles so that they could use the test data for their own marketing (none of their existing dealers had their own dyno). To be honest we are pretty sure that they just wanted to show confidence in their product but seeing as we were being paid for our time and were still curious on what sorts of results could be achieved we agreed, work is work right?
A week or so later we collected up a wide range of cars we had, crappy Fiesta diesel commute cars, more Mclarens, high milers to garage queens and the results are the same car after car - a dramatic increase in power and subsequent improvement in fuel economy.
Here are the results:
Mclaren 12c 3.8 V8 Twin turbo MY2013 Current Mileage 36,121
Peak Power before 639bhp
Peak Power After 685bhp (+43bhp)
Torque Before (4000rpm) 640nm
Torque After (4000rpm) 700nm  (+60nm)
Mclaren 650s 3.8 V8 Twin turbo MY 2015 Current Mileage 21,234
Peak Power before 643bhp
Peak Power After 660bhp (+23bhp)
Torque Before (4250rpm) 660nm
Torque After (4250rpm) 700nm  (+20nm)
Vauxhall Mokka X 1.4 turbo MY 2017 Current Mileage 18,234
Peak Power Before 138bhp
Peak Power After 144bhp (+6bhp)
Torque (3500rpm) Before 240nm
Torque (3500rpm)  After 260nm (+20nm)
All the testing was done on the same day for each vehicle, we didnt even remove it from the dyno, just dyno'd it, HydroFlow cleaned it and then dyno'd it again. The results were a consistent 6-9% improvement on power and torque and each owner reported the car actually feeling faster, more responsive and smoother.
Its not just passenger cars either, we also HydroFlow cleaned our Man 7.5t race truck, it had recently failed its MOT for excessive emissions (black smoke basically) and had been quoted thousands of pounds of remedial work, one treatment with the Hydroflow and it passed with flying colours so 'old smokey' now needs a new nickname!
So, we bought one and now we are offering the service for all of our customers. Doesnt matter if its a high end Mclaren, a daily driver, a race car, an off road ATV or the crappy train station car you dont really care about a HydroFlow treatment really can help it and potentially save you thousands of pounds of repairs, MOT failure costs and fuel bills. See here to see just how simple it is to do.

The cost for a single clean is £199 with a money back guarantee, if you are not amazed by the outcome on your car then we'll refund it, it is that good.
The process takes an hour so can be done while you wait, we also offer a mobile service (mainly so we can treat race cars at circuits) which is the same cost plus any mileage/travel time.
It really is worth a go, there is no downside.

Badger Oak Sponsors Day

To reflect the enhanced support we have had from Badgers Oak this season we decided to host a fun day out for them at Bruntingthorpe Training Ground. Bruntingthorpe is basically an airfield where you can use areas simply for fun and also a short course track to both try out cars and do some testing.

We decided to take Callums M3 as well as invite some of Badgers Oak guests along to have some fun in their own cars. Well the weather was not kind - it rained all day and the whole track had standing water everywhere but despite that everyone had a great time. We also got the chance to shake down our new Citroen C1 race car which will be racing next season.

Thanks once again to Badgers Oak and their support this season.

2018 Season Report BMW M3

2018 Season report - BMW Racing

Over the past few weeks we've had a few people ask why we've not been releasing race reports this year and whilst we dont want to disappoint our followers we did have a couple of reasons why we havent.

The first reason is that Goodwood Festival of Speed and our Yamaha racing operation really did take a lot of time from us in terms of competing, we continued to support the other Yamaha drivers and teams of course and continued to develop the Dakar spec FIA race cars but it left little time (or budget for Yamaha racing).

The other reason was that our regular driver, Callum was jumping from a 120bhp Production BMW E30 to a 320bhp E46 M3 and if we are being honest we didnt want to put any pressure on us (or him in terms of results) for the first season.

Well we didnt need to worry, the season has been fantastic, not only in terms of Callums adapting to the higher weight and power of the E46 chassis but also in terms of what we wanted to achieve.

As well as a new car we were also trying different race series with the plan to move to longer distance racing (which suited Callums racing style) so we entered the 750 Motorclub Cartek sports series as well as a couple of others.

Overall the season has been excellent, Callum quickly got used to the car and other than an engine failure at Rockingham the car hasnt put a foot wrong which is always a question mark over a new build car, but we needn't have worried.

We have been trying different tyres, different set ups and generally using this season to get back used to the E46 M3, its been a while since we built 10 or so for the CSL Cup.

Last race of the season was the best, Callum went out in the pouring rain at a miserable Snetteron and whilst nervous he really made great strides in getting the best out of the car - as the race progressed you can actually see him getting quicker and quicker, it was a delight to watch.

So now we move to stage 2 of the plan, for this year the car was a basic spec, low power, high weight and no aero at all, over Winter the plan is to upgrade the brakes, add aero, drop some weight and then for 2019 enter the MSA Track Day Championship a series we enjoyed racing in before so are looking forward to it already.

Thanks as usual to our partners, this year Avant and Swift came on board (mainly for Goodwood FoS but stuck around for the circuit racing) and our growing band of shooting related partners via Silverstone Shooting Centre but special thanks to Badgers Oak, again mainly for the Goodwood support but their interaction has helped us open new areas of development that we would not have thought of.

2019 will be here before we know it and this time we cant wait.

The mysterious Hole

We love sorting engineering issues, its part of the fun of what we do so when we come up with something that just cant be explained we do love a challenge.

Mclaren 12c (same applies to 650s) has a dry sump oil system with a catch tank that just happens to be buried right up behind the firewall next to the chassis, its hard to even see let alone get to. So when we get a 12c in with an oil leak from that area we are loathe to tell the owner that to get to it means the engine has to come out – 18 hours of work.

Anyhoo to cut a long story short the engine has to come out for another reason so when we take a look at the tank this is what we see – a nice neat hole.

Now it really does look like somehas just hole punched it, or its been pulled in from inside like a reverse alien but there is nothing around the area at all, its completely enclosed. Stumped.

Position of tank in car

Then the replacement arrives, hmmm, there seems to be a nice little seam weld at the exact point the old one has a hole in it – that seems a little suspicious. We send a few images off to a few people to be given blank looks and ‘oooh, whats that then’ but nothing back, so we move one.


Now we hear of another one, similar miles (40k) so we are now even more curious – will keep you posted.

Mclaren Chassis Work

We’ve been an independent operation since we started nearly 18 years ago and whilst we were a Vauxhall franchised operation for a while we’ve always enjoyed the freedom that being independent gives you from the manufacturer and their rules and fees. The downside to this of course is the suggestion (always made by the manufacturer or their dealers) that somehow being an independent means we dont have the skill or knowledge to work on their cars and our response to this is always the same – absolute garbage.

The reason why we can be so confident in what we do is that we have to, we live or die by our last customer, we either do a great job or we disappear and of course some do, but nearly 20 years in this business I think means that we do our job well. However what we dont have is access to manufacturer training programs so we have to learn the hard way – from experience, which is why we own our own 12c Spider, we bought it over 3 years ago and we used it to learn the cars without the need to learn on customers cars, within a week of owning ours we had stripped it down to a bare tub and built it back up, we know these cars.

Which of course is great news when we encounter a car that needs a lot work doing to it and the work is the sort of stuff that dealers have never attempted before – a front and rear lower chassis replacement.

The Mclaren range is pretty bullet proof, the carbon tub, the front and rear chassis members are astounding in their stiffness and design, its one of the reasons we got involved; sheer respect for the engineering so to have a car that has damaged front and rear sub frames (and which one of Mclarens main dealers didnt even notice when servicing the car!) means its a lot of work and requires you to know what you’re doing.

Well, 27 hours later and here is what you get, pretty much a brand new car underneath, the engine had to come out (not for the subframe but for the hole in the oil catch tank) and the whole front end comes down to replace the front chassis member. Interestingly the Mclaren instructions for doing the work are woefully inadequate and in part a complete waste of time, for example for the front sub frame Mclaren state you must drain down and remove all the front suspension, the steering which mean complete re-programming whereas all we did was keep that in place and drop the front chassis member down without disconnecting anything. The rear subframe is the same, Mclaren state engine out (17 hours) but in fact you can do it simply by supporting the engine and dropping the lower part down. Mind you, due to the fact the oil catch tank had a hole in it and thats mounted so deep into the chassis that the engine has to come out anyway we did that at the same time.

The net result for the owner is pretty much a brand new underside of the car, new front and rear lower subframes, new oil catch tank, all new undertrays and diffuser (remember the car was seen by at least one dealer who said there was nothing wrong with it – the rear subframe was so bent it had hit the gearbox!) and all covered by the owners insurance. At the same we replaced all the hose clips for motorsport specification ones and carried out a full inspection on the car so we could cover the car under our warranty.

These are great cars but they are being let down by poor after sales support and to have a dealer not notice over £20k of damage to a car that they have in for work is downright criminal. We wont name and shame the dealer here, thats not our job but we have reported what we find to Mclaren, no reply as yet.

The reason for the post is not to shame a dealer but more to show that we have a huge understanding of these cars, that not being a dealer has zero affect on our technical skill and product knowledge and that owners have other options for aftersales than the dealer network which combined with our Mclaren warranty means you never need visit a Mclaren dealer again. 🙂
