Just wandering what would be the cheapest, and easiest way to get more boost out of my novi 1220 sl. Should I just go with a smaller supercharger pulley, or should I do the 8 inch crank pulley with the Power pipe. Looking for about 8-10 psi out of it. Thanks for the help
Im sure you meant to say decrease the size of the pulley.
A larger diameter crank pulley, smaller diameter blower pulley, or a combo of both will increase boost as long as you are already not at the CFM limits of the blower.
A power pipe will help out also ( more air in more air out )
My home made power pipe picked up a little over 1lb on an 8 lb set up.
i'd make the effort to change the crank pulley first. the bigger blower pulley the better, a larger pulley will have more belt contact and go a long way to reducing belt slip.... once you get the biggest crank pulley you can, then you will need to start downsizing the blower pulley...
I agree. I currently have a SC-trim that i'm trying to get 10lbs out of. Change the pulleys first, but a AFM powerpipe wouldn't hurt anything either! Good luck!
Thanks for the help guys, I guess I will go with the 8 inch renegade crank pulley and the afm power pipe for now. If I choose to in the future go with a smaller supercharger pulley what size would you guys go with, the stock pulley is a 3.80. Also anyone know the cheapest place to get an 8 inch crank pulley and power pipe??
