Did you recive your drives? A few pic's of the drives and parts before install would be cool:)

Project started this past Monday, my mechanic said he would take pictures. I'll post when he sends. I'm hoping he will be done tomorrow.

Well you also have to remember that his 28 AT is NOT a velocity or a Kryptonite. it is a heavy straight bottom that relies on bow lift to run well. A bravo AT with 800hp or so only runs in the mid to high 80's depending on setup.

Strainers
 
Current set up has water pick ups for the Intercoolers and no strainers.

Do I install sand strainers for the Intercoolers and then install another set of strainers and pick ups for the engine?
-OR-
Feed everything through the existing pickups with just two strainers? My concern is will there be enough water volume to feed the engine and coolers?

I've been looking at Hardin Marine Strainers

Thanks

You'll need two pickups per engine. There is more than one way to do this but I believe that this set up is the best. One pick up for the intercooler to the Hardin strainer that you posted. Pressure feed the intercooler. No flow needed at idle. You will need to adjust it for pressure so will need a temporary guage. The second pick up to a strainer then pump. You will need to adjust pressure as well. Both pickups should have cutoffs and pressure relief valves. Set up will take some experimentation to get right.

Thanks, going with 4 pick ups and separate strainers.

Looks sweet.

Rik. Are the extension boxes supposed to sit below the notch? It looks like they do.
