MX5 – Exedy Clutch Upgrade

As far as I knew the clutch in the MX5 was nothing special. It had clearly been replaced at some point but I had no idea what with or how long ago. So I knew there was a chance it might not be able to handle the additional torque the supercharger setup was going to […]

MX5 – Supercharger Overheating the Power Steering Fluid

Well this problem could probably have been predicted! The outlet of the supercharger is quite close to the power steering fluid reservoir and obviously the supercharger outlet gets quite hot so on a few occasions the power steering fluid overflowed a little, I assume just due to it expanding with the heat and it was […]

MX5 – New Supercharger Belt, Spark Plugs and Oil Change

Nothing too exciting but good to document. The belt I first got for driving the supercharger was the cheapest I could find at the time in case it was the wrong length. It had also had a pretty hard time in the early days of running the supercharger while I got the pulleys lined up […]

MX5 – Supercharger Build Finished

I think it might be finished or at least as finished as any project can be. I had a bit of a move around of gauges inside. I found having the wideband gauge low down a bit of a problem when trying to catch a look at it to keep an eye on fueling while […]

MX5 – Recirculating Dump Valve Problem

When I built the supercharger setup I decided to use a cheap recirculating single piston dump valve to vent boost when coming off the throttle and stop the charger boosting at idle. I chose this over a buttefly valve as fitted to the original Mini supercharger setup for two reasons. Firstly the dump valve was […]

MX5 – Time to get the Supercharger back on

Having got the garage done and the Evo ready for sale I could finally get back to the the MX5 supercharging project I almost finished last year but just ran out of time. So I got everything out of storage in the roof of the garage and tried to remember how I’d put it all […]

MX5 – Fitting a T304 Stainless Steel eBay Exhaust

The exhaust was not the greatest when we bought the MX5. It consisted of the standard manifold, standard down pipe, some kind of bodged de-cat pipe and a mild steel cat back system that I think was just a cheap pattern replacement part. When we first got the car I did a bit of reshaping […]

MX5 – Oil and Filter Change

The supercharging plan may have been on hold while the garage was being finished but the MX5 still needed servicing so this was it’s first ride on the lift! Β Usually Jem would be my glamorous assistant but as the Mazda is technically her car and this was just a simple engine oil and filter change […]

MX5 – MOT and Fan Switch

(First posted on MX5 nutz forum in July 2016) Was very busy with the garage extension for a few months so playing with cars stopped for ages. Still need to do the odd car job though. Fan switch had died. Found this out while spending some time with the engine running on the drive while […]
