Cheers Rog, and merry Christmat to you

TBH it's all just a daft distraction to what life throws at us all eventually, I'm actually at risk of running too many Monty projects at once, but now is the time to get the jobs done while the weather is not that great.

So in addition to a few rear suspension experiments discussed on the other thread, my latest hairbrain horsepower improving scheme includes this fully ported cylinder head from AL Develolments who are the masters at porting the Duratec.







Monty also goes from his current Newman Phase 2 cams, to a set of Newman Phase 3's.



After fitting the head and carefully dialing in the cams with a DTI to avoid any 'valves meet pistons' mishaps, I should have concluded my mapping work and put Monty back on the same dyno at Surrey Rolling Road by mid March. Even after some ignition timing changes Monty refused to give more than 180hp, but he does have an amazingly broad spread of torque while still delivering outstanding everyday drivability.

I should probably stop tuning but as we know 'power is all corrupting' and I remain determined to make over 200hp, this while stubonly avoiding going down the ITB route. Fitting ITBs may come eventually, and with them Monty would easily hit 235hp plus with the new head and cams. However, I absolutely love my Fusion Fabrications long runner inlet and the mid range punch it gives.

The new target is really just another crack at my old target of 210hp while retaining Monty's pussycat town manners, I'll add an update here when the results are in.

Wish me luck, Dave
