It also has manifold pressure fueling compensation, much better for turbo applications, than the torque top fitted to the NA pumps, this should give us less off boost smoke than the NA pumps do, because it increases fueling relative to increasing manifold pressure, as opposed to increasing engine speed, which is "blind", increasing fueling with respect to manifold pressure is far more accurate for correct fueling. We should have better low to mid range power, with less smoke and more top end than the standard NA pump can deliver, due to the larger potential fuel pumping capacity. I am now waiting for Tim to get his finger out and fit it, then we'll see how good or bad it is.
The pump we rebuilt was run on veg oil, then put on the shelf for a few years, I've never seen one so gummed up, there's no way it would have run without a strip down and a good clean. Tim has the photos, which he will no doubt post up in the fullness of time, I'm sure you will all be impressed with our state of the art pump cleaning facilities.
done it myself
