city e has a 2.9 f/d so is more capable of higher speeds. Takes much longer to get there though haha.

Also, a 998 city e won't do 105. 

 

It might say it's doing 105, but even with a tail wind, down a hill, it wouldn't reach 105. They top out about 90. And that's down a hill.

For a Mini to reach 105 mph on a level road in zero wind requires around 85 bhp or slightly over. No way a 998 is going to get that in a road-going car. it would also require very high revs so low gearing would be necessary

Bhp at the flywheel is an educated guess/pub figure. The one you want to look at is ATW, which seems a little low if i'm honest. Can't believe a mini would lose so much power through the transmission if those figures are anything to go by.

For a road car, the important figure is the torque.

It was on a downhill stretch of the M25... Centre speedo said 105, so can I only go by that.
 

Maybe me ******* myself at the  time was providing extra thrust

998, 1 ½ SU, Austin 1100 unleaded head ports cleaned up slightly and compression taken up to 10:1. Electronic ignition, standard cam, RC40 and mini spares LCB manifold.

 

Pre rolling road (AAT needle ) 41BHP @4917RPM 48lb ft @ 484RPM

 

Post rolling road (custom ground needle ) 46 BHP @4951 RPM 53 lb ft @3962 RPM

 

Took it to mikeanics at Congleton, very thorough job and reasonably priced ( £80, took him about an hour and a half and 6 rolling road runs )

A Minis loss in the transmission is approx 15bhp +/- 1or2bhp
