One upon a time (in the North west) I bought a bog-standard 998 Mayfair. It had done around 40,000 miles, ran ok but not perfectly and for £500 was a good buy.

At this point in time it managed around 40mpg with certainly less bhp than the original 39 it left the factory with.

I very soon got bored with less than 40 bhp so stage one, an MG cam an a 295 head saw 60 bhp. This was great for a few years and consistently managed 40 to 45 mpg depending on conditions.

This I also got bored of, so I stuck a T2 on it (as some may know). It's not been on the RR but at a guess it has 80 to 90 bhp and is MUCH more fun. after around 800 miles the mpg is coming out at 38. And I reckon if I just calm down a bit I'll be able to get back over 40.

If only Austin had thought about turboing the 998!!

Fastest 998 mini in the world? 13.05 1/4 mile 106mph

Great news.

What sort of mileage have you been doing - town, motorway etc???

As you know, my prime objective of turboing my 998 is to achieve a reasonable power level and still get good mpg.

Final drive is 3.1 (the whole engine below the head is as it left the factory)

The car is mainly used for commuting and tossing about around town. The commute is all A-roads (no dual carriage ways) and I usually cruise at 70 (indicated). There are two towns on the way and one at each end, which is about 20% of the journey in 30/40 areas, where I generally stick to the limit (well no more than 5mph over).

Well, that's even more encouraging given the fact that your not just sitting on a dual carriageway at 70 most the way. More akin to a "combined" figure.

On a 3.1 diff as well.

I'm hoping for 50mpg plus with the fuel injection - if we can get it to work!

I built my NA 1275 with economy in mind with an SW5 and a 2.76 diff etc.

I get good economy, 40-45mpg and it's quieter, but it performs like a standard 998.

But ultimatley I find driving it slowly to get good economy very difficult. It brings out the teenager in me!

Building a high MPG mini is something I am interested in. My NA MG mini only gets 35, although now near 38 with the MJ but I am hampered with a 3.44 and 10's and do constant motorway driving. A force fed 998 on a tall diff sounds like the way to go. Good work!
