under 9lb I believe you dont need an intercooler (your not compressing enough to raise the inlet temp that much) and you can run a non indexed fuel pump, but if you already did it, good to think ahead. Where did you get a wastegate for $10, thats the part I need and they are more than the turbo I bought! The small hole in the casting that looks like a flaw is there to vent the area between the 2 seals as it varies in volume when its working, if you seal it, you might get a "harder" spring pressure is youll be compressing air too. I mounted the blow off valve behind the carb so as to keep the flow in that direction. If you blow off before the carb (like on another leg of the ram tube) it will change the direction of the flow and may effect the next time you mash it like off a turn. keep showing and telling!
