We decided on reflection to not go for the Turbo - the specialist who supplied the engine really 'knows his st' - we wanted to try and keep to AJP type power delivery and especially wanted to reduce the amount of Torque which is really hard to deliver in such a light car, so the Cam we had hand ground is going to give us 500BHP+ but probably 425-450lbs torque, it will be like the AJP a bit lumpy at low end but through mid+high end rev smoothly. (best made plans and all that....)
We decided given that were lightening the car considerably that 500BHP per ton was plenty for track use! And we also felt the extra money was better spent on suspension which is going to be heavily modified.
Engineer1949 can answer the detail of the ratio's we selected.

been busy today stripping the internal panels and sundries like the aircon unit brake clutch pedal assembly the heater matrix winscreen wiper assembly expansion bottle oil cooler plus a few other bits, just as an aside found lots of very thin layup in several places, but got to get the steel cage out tomorrow ready for a proper roll cage to fia standards going to do a couple of days on the wedge then back on the cerb next week get the body back on the chassis ready to go to the rollcentre.

Thanks for the good words,itis going on an engine dyno for mapping and running in the chassis will be painted using zinc primer high build undercoat then a high solids finish same as the griff i re chassised a a while ago means no water tracking under the powder coat and very easily repaired touched up.

couple of pics of the heater and aircon first two are the aircon drivers side then the left hand unit on the floor is the heater then the space in the inner wing in the foot well where the heater goes it is held in by an ally strip and a very awkward screw at the top into the glassfibre hope this helps.

Body on to allow correct fitment the cerb has the roll cage running close to the body shell which is then glassed in to provide stiffness to the body so all needs to be in place to get it spot on plus they are stiffening the chassis with a front turret from the suspension arms top mounts then braced back through the bulkhead to the cage plus might be fitting air jacks all round.
