With the existing bypass-valve system the charger uses .5 bhp when not boosting, after I've settled on a pulley-size and chased the Gremlins out of the other systems, I'll see if I have enough steam to do a lap of upgrades and weight reduction of components.
When I swap to a 3.6" supercharger pulley, the boost should be up to maybe 14psi and begin sooner, in fact I think the current 'behaviour' of the transmission is keeping it off boost @ low revs.
The engine-conversion is now running fine and under observation, I want to just let it get on with it's job for a while and move on to the transmission.
First to second changes are too slow and I suspect the solenoids are gumming up, also, @ high revs maybe there are too many volts for the Suprastick to read.
Further to a two month wait, now two Parcel Force delivery attempts failed to find my address, the modified valve-body is presently lost somewhere at the Leicester Depot.
When the cows are laying down in the field and this eventually gets fitted and the over-volts 'maybe' issue resolved, I can then have a good fiddle with the torque converter settings and find it's sweet-spot.
I have over-legged the gearing too, I'll keep the 40 profile 18's yet swap the T.T. auto 3.769 diff, back to an N/A 4.083 Torsen with a T.T. flange.
