Improving Your Mini Cooper Gas Mileage

by Don Racine
Most engines (and all Minis) use an electric spark to start the burning of the fuel/air mixture which in turn powers the car. If the engine is to run properly this 'electric spark' must happen at the exact right time.

Mini Cooper Verto Clutch Information

This article has been written owing to the increasing amount of people who ring Mini Spares stating that their 1275cc Injection type Mini will not start after fitting a new clutch, especially when they have purchased the parts from another supplier, usually a motor factoring company, rather than a Mini specialist.. There are 2 types of Pressure plates, namely AP (Automotive Products) and Valeo.

HEAD ALLOY 5 PORT ALUMINUM CYLINDER HEAD BARE
 
There are several advantages inherent to an aluminum cylinder head including a great deal of weight savings and considerably improved cooling. This improvement in cooling means we can now run higher compression ratios without detonation caused by localized hot spots.
Other improvements to this head are less obvious; for example, flow has been considerably improved by reshaping the combustion chamber. This was made possible by relocating the spark plug and upgrading to 12mm plugs. Early tests indicate that this head right out of the box flows comparably to a Longman GT6.
The heads are supplied as shown, with bronze valve guides and hardened valve seats installed and valve springs seats, but no valves, springs or studs. As standard the head is ready to fit 1.15" exhaust and 1.31" intake valves and has a 23cc chambers with a thick deck to allow for plenty of skimming.
Largest valves that might be fitted without changing valve seats are 1.48" intakes and 1.22 exhaust! How does it perform? We've run one on the dyno, and here's what the numbers look like. The test engine was a 1275 with .040 flat top pistons. Test #1 is a stock cylinder head, test #2 is the Aluminum head with standard valves.
RPM HP#1 HP#2
3000 47.80 47.60
3500 56.12 56.97
4000 64.22 67.23
4500 70.31 73.30
5000 73.50 76.30
5500 72.93 79.25
6000 -------- 80.27
As you can see, the aluminum head shows a measurable power increase above 3500 RPM, and, whereas the motor would not pull beyond 5500 RPM with the stock head, with the aluminum head it pulled past 6000 RPM! Flow bench tests show the alloy head outperforms the standard at all lifts.
Also, early indications are that this head responds well to mild porting above the valves.
Uses spark plug RA8HC.
