Looks like my super chillers,I was under the assumption the
PSI generated less heat with the screw type rotors.
Dusting had mention some big gains with his coolers,I might
try them with the 1471s just to compare.Then move up to the
PSIs or 5.5s. Are you going to run the same set up to compare performance gains?

Roger at PSI mentioned at idle and low rpms the Blower is actuall trying to create boost at this point it is creating heat.
Where the PSI becomes an advantage is the faster it spins the
more efficiant it becomes.



Dennis who runs the Predator Apache and Tommy at Chief
confirmed a 80-100 hp gain just going to the PSI,s.

I am by no means a supercharger expert. But a PSI
overdriven at 40% is gotta sound cool!

WHAZ UP JIM????

Hey with all the advice you have given I should send ya all
my props
The 37.5 are actually on there way to Herring along with the lowers.

Chris Flood says HI!!! He,s suppose to call ya.
He helped me out Great Guy!

I'm rebuilding my motors right now and won't need the props until March. Your right, Chris is a great guy. Tell him hello.

I got the same info on the whipples creating alot of heat at low rpms. I still just ran off of the strainer. I have seen a few of Sterlings where they run the main feed (-16 I believe) off of the strainer but also tee in a smaller like -6 or -8 from the belhousing to give it some cooling while idleing. Some people think you can get to much cooling off of the Sea Pumps at Idle with a carb set up and get fuel pooling on the intercooler. I don't know, just passing along others info.
Anyway, good luck with the project and let us know how it works.

This picture is the new 5.0 whipple see the opening this is to allow a vacuum controlled valve to bleed off the idle boost.
Feed it back under the charger. This was suggested by Roger.

Pretty cool But where the heck are ya gonna put it on the PSI?

I agree!!!!

That 5.5 X Dim Sounds A Little High Curius On How Your Measuring We Dont Even Run That On The Race Boat Good Luck With The Psis

I was thinking the same. After talking with a South Florida
Rigger he sets some up with that height.

Mine is at 3.5 inches above the bottom.
Peter told me on my hulll should be between 2.5 to 3.5.
Using a 4 foot level. I leveled the boat on the trailer.
Then level the drive with the trim. Then run the same level
inline with the bullet of the drive.
Holding this level up against the bottom and measure from prop centerline to the top of the level.

Thats The Way I Do It And The Most You Will Usally Find On A Race Boat Is About 4 Inches Keep The Updates Coming Glad To Help In Any Way Im Out At The Toy Factory A Lot Down In Sunny Florida Right Now Sitting By The Pool Not To Rubb It In Went To The Pri Show Neat Stuff Talk To Ya
