Going a bit backwards in 2019 as I posted from later in the year.
So in March 2019 MOCSA had a dyno day organized. I changed the oil and re-torqued the cylinderhead and set the timing as best as I could man alone. At this stage the car was still running the Twin HS2 carbs.
So to make a long story short and to just stick to my own dyno results....
The car made 43,1 KW on the front wheels at 5800 rpm, that was good enough as the most powerful 5 port NA car on the day. To put this in perspective, Raz's bog standard 1098 estate made 20.5 kw and a fellow member with a alloy 7 port crossflow head fed by two 40 DCOE webers made 67 kw, so I was disappointed with that to say the least. That is why I decided to fit the twin HS4 carbs.....
Not too long after the dyno day it was found that the springs in the dizzy was past their best, so they were replaced. Compression was down on 2 cylinders still, so oh well. Another opinion was that I should have let the dyno operator rev the engine to 7200 then the power band would have settled.
So after the engine rebuild in June/July 2019 the small HS2 twins was refitted.
Onto Cars in the Park early August so I was invited to show the GTS at the pits.
Keeping some excellent company.

Own some minis, break them, fix them, improve them, test them to the limit....
