Thought I'd just clarify a few bits and bobs due to PMs and questions asked of me.
The engine wasn't put together to be the best on economy in the world nor to be the fastest ( wouldn't have chosen a Pinto if I'd have wanted that !) , just to be a torquey robust usable motor on an AUTO. What I've been trying to achieve is the best MPG from THIS engine combo in this vehicle and working within certain limitations. The engine is meant to make around 140 bhp against a stock figure of 115. 140 is only a little bit shy of a 3 litre v6 output that'll give you 25 on a good day.
Pinto is vastly lighter than than the V6 but the big killer is the amount of torque from the V6 . The back axle is a 4:1 to get the overall gearing required and is the weaker of the 2 Cortina axles. The A is producing enough torque to make the axle tramp and with the latest timing set up it's more torquey than ever.
The timing figures for the FR30 and the FR34 have been shown earlier and the difference in duration of 3' produces 4bhp more. This is down to the higher revs achievable on the FR34 injection specific( quoted at 20bhp gain )with a power band from 1000-6250 as opposed to the high torque/towing /automatic recommended FR30 producing 'just' 16bhp additional with a 1000-6000 power band.
0-60 is pretty much the same as my old POS which weighed around 15cwt with about 120bhp ( with 33mpg being cautious and 27 having fun) so I guess I'm pretty happy ... I still may play with the visor to improve aerodynamics ...and I do have an opening screen in the corner of the garage as well... LOL
