I think the limitation of the diesel engine is actually in the fuel system . Power programers alter the fuel system and timing , there is nothing electronic on the turbo to alter with a programmer . The trucks you see with higher psi have had the wastegate modified , sometimes with a boost controller , but nothing to do with a programer . The turbo dont know what its hooked up to , it just spins with exhaust pressure , if its hooked to something that can make more rpms it is going to spin with the extra pressure made by those rpms . I dont know anything about sizing turbos , but the engineering behind the operation of a turbo seems pretty basic . I dont think it could over spool if you have a wastegate setup to dump at the correct pressure .

I'm no turbo expert by any means. That's just stuff I've read about about a diesel turbo on a gas motor. I think has something do with the viens. There's more of them so the hot side spools at lower rpms while the cold side pushes a more psi at lower speeds. My F250's redlive is like 3,200 rpm. That the range the turbo is designed to work in. Some people say it will work, others say it won't. I'd go for it with a good waste gate keeping at 8 psi on pump gas just to check it out.

Just make sure the motor is mounted with a 4-point.. LOL

From what I am finding the only real important thing for the turbo it self is the CFM , and where it makes it . If you have a turbo the produces a max cfm of 450 it is probably going to hurt the engine more than help it . The veins and all the rest of the stuff does come into play in determining the CFM a turbo is capable of , but the thing you need to know most is the CFM . I have not yet found the CFM information on the turbo in question to be able to say if it will work or not , but I really want to know what to expect before I decide to lay out the bucks for the rest of the system . To make the turbo work there are alot of other changes that will need to be made , and alot of money to be spent . If this turbo will not be any good I want to know before I jump into it . I might be able to run a different turbo for my setup and not spend that much more than what it will cost to make this one work , not sure . I am waiting to hear back from a guy that knows LS motors and turbo setups on LS motors really well . I will go with what he suggests for this particular setup .

Yep , seen alot of power bolted to a regular old three point . Mine is not going to have near enough power to worry about breaking the three point , I just wanna be able to run down the faster of the slow boats .  :smile30:

:huh:  i thought you were going with that front mount three point.....  think.gif

UNdecided on that one , but I am using a three point rear mount . I might go ahead and fab something up to use the regular side mounts on the motor instead of the front plate setup I had been thinking about .

The regular three point will handle tons of power. The morphadite three point is another issue.

You do lose some torque and power with a three point, and with more power you also will put more stress on your boat...just my .02...

I had the water pump plates cut , just need to drill and tap them . Alot cheaper than ordering the ones available online too  :smile13:

So , what size do y'all think I should tap the holes out to ? I know there is a link to the ones available online here somewhere , but I can't find it at the moment .

Knowing me , I will get all ghetto fabulous and put some nice shiny brand spanking new heater hose on it . Not sure what size , probably 3/4" .

Your probably gonna need to tap it 3/4 NPT for the barbed fittings for 5/8 heater hose.  I'd get the fitting first and then drill and tap to match.

So , I've been reading up on it , and it seems like the best option would be to scrap the powersmoke and just order a new turbo for the LS motor . I am still thinking  one big ass turbo instead of twins , I have read that one will spool faster than twins . Any one know anything about setting up turbos? Still waiting to hear back from Tom , he hasn't been around much lately .

Just start researching turbo mapping. There is a science to it, but not too complicated! I have a front motor plate for an LS motor. Came with a car I bought! think.gif

Yeah , I have been doing some studying on the Turbo Forums , they have an LS section over there . I have seen several setups that look pretty good , and are not that involved , but I am not sure I want to have to track down E85 every time I fill the boat . So , it kinda complicates matters a little bit . I just want to see if the turbo is a good option before I have the heads milled , right now they are at a good compression ratio for a turbo setup . It would be a really cool setup with a turbo , but probably still not really all that fast . It is still a really heavy v bottom boat , it would take alot more power than I want to build to make it really fast .
