I posted about this over at Focaljet.com
Check out the
post.
I discovered that BMW is currently working on a new 2.2L DOHC I4 "M" engine that will put out 240hp at 9,000 RPM. All engine!
That would be the ideal next engine for the MINI IMO. Leave the sacred MINI Cooper S name alone though.
Also the June 2002 car and driver reported that the Cooper S's supercharger is capable of blowing 11.6 psi at 14,000 RPM. The problem is the engine shuts off the power at the computer controlled 6,800 redline.
The cool thing about this is that by chaninging the diameter of the pulleys that are related to spinning the superchare it is possible to make the supercharger spin much faster and boost more. Adding boost also require fuel and air adjustments which can be modified with a customized computer program (CHip).
I would like to see a 250hp tuned S!!!
Best bang for buck modification has to be a boost upgrade kit. No doubt about it.
