Jet Pumps / Impeller starting point help

« on: April 20, 2012, 01:19:40 PM »

Okay I am working on a Crusader tunnel project, that is going from a Blown BBC to a Turbo LS. The Berk pump currently has a stainless AA, and I am sure this turbo LS is not gonna turn it well. I have done a ton of high horsepower 4cyl stuff in the past and the hardest part of the equation was getting the converter right. I'm not saying that a pump is exactly the same, but they do share similar loading characteristics. I am leaning toward a B/C cut with the thought that is will be loose enough to let the turbos light and then load it down properly. The motor should make about 800 on moderate boost, and will happily spin 6800-7000. I am not expert, and looking for advice. Thanks in advance...

well after going back and forth on what to do, I decided to go for it. I have wanted to do an LS for years now. My brother has a LM7 that has been sitting for months just calling my name. After going back and forth we decided to try some different combos and just have some fun. A fellow board member came through and gave me a mock up block to design some motor plates and I have been hard at it. This weekend we pulled the BBC and prepped the boat. The boat already has a nice fuel system(carb setup), so we decided to use as much as we already have. The plan was to go EFI single turbo, but the budget started to get a little out of hand. In keeping it simple we decided to go with an E85 blow thru setup and see what it'll do. I have plenty of experience with efi systems and tuning, but have always wanted to see what all the blow thru fuss is about. I am hoping to have the engine in the boat within the next few days, and get all the details sorted before the carb shows up in a couple weeks. I am still missing some parts small parts so if anyone has a line on some stuff(starter/flexplate/alternator) I would appreciate the help. So here we go...

BBC out

Getting all the dims, its was a pia, had to be creative...

I need a hopefully bare block and timing cover. I want to throw it in the mill and grab all the holes and draw up a mounting plate. Any help would be appreciated...Lance 619-554-7108

Thinking about running a boat on Sunday. How anal are they with exhaust battles? The boat is pretty loud. What time do I need to be there?

I have been lurking around this site for awhile, and enjoy looking at what other people are doing with projects. I have done a bit of high hp turbo import engines(drag cars, sand cars, etc.) I have been doing more and more big inch turbo stuff, and have had an ex drag boat(jet) fall into my lap. It has a 500+ blown bbc, with lots of supporting hardware. I am thinking of ditching the supercharger and carbs, in favor of an EFI, intercooled, big turbo setup. I keep going back and forth and just want some feedback...
