Right an update....

As far as I know, It's a standard 998 with a stage one kit from minispeed. Compression ranges from 180 to 190 so I'm not sure If that's normal or high FOR A STANDARD 998? Definitely higher than any of my old cars though,

It was running really lean and the timing was 0 degrees.. I have (with the help of friends and family who know a bit) adjusted the timing to 10 degrees at 1000, and made the air fuel mix richer. I also swapped plugs, leads, dizzy cap, rotor arm, oil and filter and it now seems to be better, although it still gets near the top of the gauge when on long uphill stretches.

I'm not sure if the old rad was uprated and I've chucked it now.

I can definitely say that it is going like a rocket compared to before so something is right!

I have booked into ML Motorsport for a good check over and a proper tune up so hopefully they'll suss it out.

Thanks to everyone for your help.

Erm... The fan WAS the wrong way round.

My local garage obviously don't know about minis. Set timing wrong, set it running lean and put the fan on wrong way round. I'm glad I'm having a go at things myself now and thanks to you all for giving me advice and confidence to tackle these things. I've had the rad in and out, adjusted timing (with help I admitt!!) and given a full service.. all using threads from this forum.

I think doing it yourself is the way forward

So have you tested it ?
