It’s time to sell the MX5. We bought it on a bit of a whim nearly 3 years ago and it’s been great, never let us down even though it’s 26 years old and I’ve nearly doubled it’s power with the supercharger. We will genuinely be a bit sad to see it go but I […]
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 […]
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 […]
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 […]
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 […]
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 […]
Having done a few miles in the MX5 now with the supercharger on I’ve been giving everything a regular look over to keep an eye out for any problems that might come up. Well I noticed the other day that it looked like there was a light coating of oil over the exhaust shield […]
(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 […]
(First posted on MX5 nutz forum in May 2016) Not got too much further cos I’ve been busy with the other cars and other stuff but I have some updates. Once I’d proved the substitute IAT sensor was going to do the job I thought I’d go ahead and do the MAF to MAP conversion […]
(First posted on MX5 nutz forum in May 2016) I will only need it if/when I get as far as running injectors directly from the DET3 but I thought I’d see what I could do about providing a proper variable TPS for the DET3 while keeping the OEM 3 state TPS for the OEM ECU. […]
