I have been running my Powerdyne BD11-a for a little while using the 6lb pulley and so far have been pleased. My question is would you recommend going up to the 9lb pulley and would it make a big difference?
I am running 36# injectors. The car was last tuned by the previous owner. Then he had it dyno tuned. The car does have a chip and a wire that runs from it to a little knob mounted on the console. I asked the prvious owner about it and he said that it was an old tune and not to use the little knob. I did look at the computer and found where the switch plugged into the card. However it was unhooked.
My current setup is as follows.
306 forged internals,Typhoon upper and lower with BBK 1# spacer ,BBK 75 mm throttle body,GT40 heads,Ford e-cam,36# injectors, Maf tuned for 36# injectors, BBK longtube headers,BBK H-pipe with Flowmasters, 373 gears. I just wasn't sure if the Powerdyne supercharger could take it. I have heard a lot of people having problems running at higher boost levels.
