Re-dynoed this Turbo setup today. It made 69-70kw atw the first time which I was quite happy with considering it was a std 1200 motor with a gasket kit and a set of rings.
It runs a suck through CD Stromberg, very basic and simple. It had a std air filter with a sharp edge at the entry, which I didnt think would make that much difference on a turbo setup...???
I made a little half/donut-ram tube for the air filter, retuned the mixtures (had the carbie apart) and ended with 80kws, pretty happy with that!!  I put a couple more degrees of timing in and it lost huge HP, 58kw 
I went back to where I was, then took a little more out, BINGO 84kws!!
Took a little more out, 90kws!!
Took a little more out, 96kws!!
I didnt want to take any more out, just incase it went better, as strange as it may sound. I had in the back of my mind that motors usually go there best before they go bang!! Plus it still has 30year old std pistons in it!?!?
It wasnt pinging before, but obviously wasnt fully happy with where it was. Its seems very happy now
