Harrop 2300 supercharger to Optimiser 6500

[PeeBee]

Hi Pee Bee,

no the fitting at the rear on the manifold next to the super charger, for boost pressure measurement.

Your manifold must be different to mine as I dont have a fitting for boost pressure take off. I had to tap a hole in the manifold myself, and simply use one of the inlet manifold 'legs' with a 1/8" BSPP tapped hole for my pressure sender. I have just checked this now and nothing there, and would have used it if it was. Sorry. Maybe ring/contact Bullet as they supplied the manifold? If you go from the back, into the chamber, be careful regards the i/c core in there.
