Okay, let's have your estimates on this MPi - it's going on Southam Mini & Metro Centre's Rollers Thursday afternoon so I'll post the results that evening.

Just been checked over on Dave's (Icklemini) box of tricks and set as best he can (still thought to be running a bit "lean" thus a bit of a "Flutter" when crusing/feathering - hoping pressure adjustment may cure?)

Specification>>>>>>>>

- 1998 1275 MPi
- 1.5 Roller Rockers
- LCB, de-catted and with RC40 Back Box
- 52mm Throttle Body
- Cone Type K&N Filter
- Head appears to have polished ports (rather than actually opened up)
- Power Boost Valve (Fuel Pressure Regulator)
- Cam type not known but John Guess thinks it may be non standard (hotish?)
- Icon Race Superchip

other info (if needed?)

- 5 speed TRAN-X Box
- Quickshift
- 13 x 7 Superlites (175/50-13 A539's)
- Injectors ultrasonically cleaned and calibrated (balanced when checked running)
- All sensors replaced (apart from Crank Sensor)
- New Coil Pack
- New Leads
- New Fuel Filter
- New BPR6ES Plugs
- etc, etc.

Apparently, when first built by AEG of Birmingham, it was supposed to be equivelant to Works "S" spec'n which I understand was 90 BHP???

I await your estimates
