Litchfield sell and install the Cosworth Supercharger, plus they have also made changes to the ECU programme for the UK market, go on www.mx-5.com there is a chap on there having one fitted by Litchfields (I think)

Thanks. I called Cosworth last week and they confirmed it was available in the UK for £3k plus the dreaded VAT. They also said it would be on mx5parts.co.uk "soon", which was obviously true!

Apparently it takes 12 to 14 hours for a competent fitter to install.

They claim 220 RWHP over in the US

Yes with Cosworth Supercharger

US rwhp usually equates to crank hp over here. It'll be interesting to see the first UK car on a UK dyno

Theres a chap on MX-5.com who is going to have a Cosworth Supercharger fitted here in the UK, I hope he takes it to an independent rolling road to verify what the car is producing.

I might be wrong but I didn't think there was (yet) a version of Cosworth's SC for right hand drive cars? If there is, can someone post me a link?

Don't have a link, but they definitely do it (I have regular dealings with Cosworth PR and it's very much the next big thing... they had a mk3 MX5 on their ASI stand a few weeks back)

From my enquiries, it's 240bhp at the flywheel. If you go onto the Cosworth UK site, look at the Performance Parts Catalogue and go to about page 34 or so, it's all there. I think there's a graph for power and torque, too. The installation is really tidy - more so than the original, I reckon.

I called mx5parts.co.uk today. They take one week to come in on back order. The cost is £3400-odd, including VAT. You get all you need in the box. Except tools and a good spannerman.

Apart from the expenditure, I am struggling to see a downside to it. Apparently, mx5parts have tested it on their MK3 and the chassis is more than up to it. I suppose the warranty will be down the toilet and insurance could be interesting, but hey - you only live once.

One last bit of info: your car must have a/c and power steering in order for the kit to fit. There will shortly be another kit for those cars not having these.

Cheers.

Here's some interesting footage...

In this month's EVO. The Litchfield suspension / S/C and ECU package.

According to Goodwin in this week's Autocar (Ask Goodwin), the supercharger might not be such a good idea. He thinks the gearbox and diff are at risk. I disagree. Any thoughts?

[GravelBen]

The 1.6 diff is a bit weak for FI I think, but its an easy upgrade to the bigger, stronger unit from the 1.8.


ETA: Oh, looks like you're talking about the Mk3. In that case, I have no idea and should have read the last few posts first.

It's true. It's always going to be true when you add more power and torque to a drivetrain. It was designed for something in the region of 160bhp with a margin of safety. Adding power & torque will remove some of that margin of safety.

With the Mk1, 2, 2.5 we know how strong these components are because so many people have boosted their cars and found the weak points (or lack of them). The Mk3 is an unknown quantity. Until the numbers of owners with boosted cars increase and they start usingh these cars more heavily on road/track/strip we won't know if there are weak points in the drivetrain. The first takers are always the trail-blazers for those that follow (just as the first takers are basically beta-testing ecu maps).

ETA: I'm not saying it's true that the supercharger might not be such a good idea, just that it might be true that the gearbox and diff are at risk. Until people have tried it we won't know for sure. I'm sure the Mk1 gearbox & dif isn't rated for 250bhp / 250lb/ft but there are plenty out there with this much and more.
