Another mini project completed today. Came across these rather nice milled aluminium carpet fasteners on eliseparts. Bit expensive but hey ho! The original plastic ones do look a bit tacky. To fit them you first have to remove the original ones which is not entirely straightforward;

Step one, remove your matts and pull the base carpet up to expose the fixings. Draw around the fixings with a pen so you know the positioning.

Step two, remove the threaded plastic mounts. They are glued and rivetted down. I used a wood chisel to pry away the plastic molding.

Step three, remove the rivet heads. I used a hacksaw blade laid flat against the floor. It takes a little elbow grease but isn't too bad.

Step four, clean the exposed aluminium area on the floor. The new fixings come with PU sealant and adhesive. Apply the sealant quite liberally to the new threaded aluminium bases. Fit the mounts in place and leave for around 3 hours for things to take hold.

Step five, push the carpet back down, put your matts back in and screw your nice aluminium retainer caps on. 

All done!

Okay, carbon engine cam cover install, the ins and outs...

I've had a week off and the purchase was a spur of the moment purchase. My car came without any type of engine cover and I've always thought it looked a little unfinished.

I did a quick search and eliseshop turned out to be the cheapest and also had everything in stock. I ordered on bank holiday Monday and my order arrived on Wednesday via UPS. I'm not sure how the Brexit thing works at the moment as I've ordered stuff from Germany recently and it came through with no additional charge. With this, I ordered but didn't appear to be charged VAT. I was then charged by UPS... Anyway, arrived very quickly with no delays.

Quality of the carbon panels and molding is very nice, I'm not sure who eliseshop use but these are good. I had to order the fitting kit which is essentially 2 pressed steel brackets, 3 rubber grommets and a selection of bolts, it's very expensive at around €100 but you can't do without it, sooo...

First job was insertion of the rubber grommets onto the underside of the larger carbon panel. The first issue was that the fits a bit too tight, also the rubber grommets have a little nub that'll need to be sliced off. Out came the Stanley knife and I shaved the grommets down a fraction. After this you can twist and push them into place.

Next, working on the upper cam, you need to fit the 3 steel ball mounts. Two of these are on tower nuts, this is straight forward, they screw into 3 threaded holes in the top of the engine.

Then onto fitting the brackets to mount the lower, smaller cover. This is where it becomes a bit of a pain. Starting with the right side bracket, it is secured in two places with two bolts. The first and lower attachment point is simple, the bolt which already holds a metal tab in place on the engine is removed and the tab on the new bracket slips under the existing tab and the bolt is reinserted. The upper tab on the bracket is a pain in the arse. There is a hole in the triangular steel bracket onto which the super charger pulley cover is mounted. In the supplied kit, there are bots but no nuts. Fortunately I had a nyloc in the right size. Threading this bolt through the hole in order to secure the upper part of the bracket requires some serious finger yoga... At one point I did drop a washer which ended up down by the pulley cam but it was very fortunately retrieved using a home made magnetic tool 😁 Next was the left side bracket, there are two existing threaded holes on the engine onto which this bracket should bolt. Accessing the upper hole is tight but doable. Accessing the lower hole would require the removal of several additional brackets and wiring clips which I decided just wasn't worth the effort as the single large M6 bolt is more than man enough to hold the bracket in place.

Finally, attach the supplied spring clips to the smaller cover and then push both the upper and lower covers into place. Coat em with your choice of ceramic product and the jobs a good un!


Thanks for posting about the engine covers, I’ve just fitted mine that I also got from Elise-shop but have a question about the bottom smaller cover. I attached the tower clips to the cover and pressed into place but the cover seems loose and will move around. Is there something I’ve missed when attaching the clips? When I press the cover into place, the clips seem to push through hole in the bracket. Any help be appreciated.

I’ll take another look later and see if I’ve been a bit to heavy handed when putting it on. 
Thanks as well for the post about the carpet fasteners. I’ve had the same set for a while now and not got round too fitting them. Your instructions will be very helpful! 
Good work with the you tube videos as well - lots of useful advice 🙂

No, it uses the original supercharger but adds a charge cooler underneath, fed by a front mounted radiator. This allows them to squeeze maximal boost out of the original unit as they can optimise the intake temperature.

Nice project this - by now you must have done every single upgrade to the car!:)

It might have been mentioned but I take it that you have also upgraded the clutch to cater for the extra torque/power?

Mainly for educational purposes, what is the difference between the Komotec solution (chargecooling on the base of the existing SC unit) and the 410/430 in regards to the supercharger application? Thanks

No not yet, it's ran 430 for 2 years and there's still no slippage so I'll get it done when needs be...

Main difference is that Komotec also utilise an additional front mounted radiator. Also their map is more aggressive and produces more torque. 460 is notably faster than a factory 430.

Thanks Mark. So how is the cooling achieved on the OEM application then? Just air from the side vents?

To the untrained eye (like mine) there are substancial differences when comparing a 410/430 to a 350/380 EX460 kit. The former is a big square box like the Harrop unit (I suppose the cooling bit is incorportated with the SC) and the latter has the supercharger sitting on the cooler. Any benefits/drawbacks of each?

I think I read somewhere - don't quote me on this of course - that the stock SC is already on the edge of its performance on our cars - I take it that with the chargecooler the stresses are less as it operates at lower temps?

Bit of a silly upgrade but I'd installed a dab Arial some time ago and fancied having the ability to use it. I currently have the SPH10BT which is a fantastic little unit for the money and had got much better over time with upgrades to the software.

So now I picked a SPH20 DAB off eBay for £100...

Not a massive detailing guy but do keep my car clean. 2 years ago I had Gtechniq crystal serum light and Exo applied to my car by an independent contractor. It's hard to tell how much difference it has made to the durability of the paintwork but it's definitely remained very hydrophobic. I do top it up pretty regularly anyway with various quick detailers from Maguire's and Beadmaster but the car has still developed light swirls over that time. This, all despite being very careful and only using descent quality cloths and mitts.

Having been recommended I visited Petrol Head detailing today who are an accredited Gtechniq dealer. After some discussion I've opted to go nearly the whole hog and I'm having crystal serum ultra applied in a few weeks. I've been told it's considerably harder than light and that it also comes with a 9 year guarantee. So, I guess we'll see...
