Greg, I was told you were the person to talk to. I have an 89 Crusader laid up pretty heavy. Once upon a time the boat was called Too Trick for Dick and had a 580 Twin Turbo with iron heads. The boat made a wicked right hand turn at 85 mph. I bought the boat and have had a 468 twin turbo, and I don't think I have come close to that magic number. The 468 gave up the ghost and I am now building a 540 twin turbo for it, which may bring me closer to that point.
The loader is about 25 years old I would guess. AA Berkely pump built by Doc Jet with not too many hours since being rebuilt. I am guessing it is about time to change out the loader. With the 468 I never had any cavitation issues, though I know the 580 did, but was also making about 25 lbs of boost, where I think I will only be in the 12 to 15 range. I am going Aluminum head, so saving a little weight there as well.
Any suggestions for a loader? Or should I just have mine magged? Thank you!
