Hey guys, I recently picked up a used 175HP1 6-1243 2.9 whipple. Seems to be like ZERO info on the internet about this thing. Does anyone know how much boost its capable of? I thought it was a newer one but they are the W157hp's and I have no idea the differences. Will it still put out 25 lbs of boost?
