Hi BBarn

I was thinking of a reverse inlet too, my freind Bob Patterson has a Allison powered Unlimited hydro and when they started to run the turbines the salt water in Mission Bay it really messed up the engines.

Bob told me what they did to solve the problem.

As i recall the turbine guys built intake scoops with air diverters inside the scoop to keep the salt water out and air in , maybe a style like that for the turbo intake where the salt sticks to some panels and lets the air in.

Hi Rob

Don't they have draged turn outs that connect to the return road, so you don't have to run over those little crusty ridges that run everywhere?

Don

Don, yes they drag turnouts... some are gentle curves off the course, but still intersect the return road at 90 degrees, probably work great if you are in a roadster or a bike... not so much if you are in a vehicle that can't make a 90 degree turn in 30 ft.... One of these days someone will drag them so they just angle over to the return road... it is not important for the turn out to make the race car turn around and go the other way.  Based on the tracks you see, most can't do it anyway.

Most of us would rather drive through the crusties  with the race car on the trailer.  :cheers:

There were a couple on course 3 last year that were corkscrews!

Don,  any chance you could get your buddy to hand draw that arrangement so you might share with us.



did it all come through the frt. opening,, water hitst the backwall and drains out the bottom, but the air was drawn out the double wall sides, back near the front opening  :? IMNTK

Hi Sparky

I was just thinking that maybe Bob had some type of deflector too, to keep the salt water out of his turbo on the Allison.

Not sure if he knows what the Turbine guys did as they were the enemy camp to the Piston Packers

Will ask him tommorrow as he might know a boat wrench we can ask for a sketch.

Due to money constraints, we have decided to partner up with Buddy Walker and run his flathead in this streamliner. Sort of a divide and conquer thing. Our BBC is a bit of a grenade as it is still a stock block and has about a million laps on it. Next year I should be able to put something together that I know will live.

I see - so you'll be running the caddy engine THIS YEAR.

The flathead will have a reverse turbo to suck the air out of it to make it last even longer.
Well, it used to be Los Angeles . . . 50 miles north of Fresno now.
Just remember . . . It isn't life or death.
It's bigger than life or death! It's RACING.

Well, I understand running 10"-15" of vacuum can result in a 3-10 HP increase...... :-D

Buddy and Rob,
This is a pretty aggressive move this late in the year. Lots of things to make happen when you "switch horses in the middle of the stream." I assume that you almost have to run the Cad with the top mounted 6-71 so there is going to be some big time additional body work to get the bumps and notches of the injector scoop and blower covered and "aero-ed up". Love the idea sure hope you have a reserve of 36 hour days!

We are going to a twin turbo setup. Same bodywork. Actually looks like a much better fit.  :-)

I've posted about having turbos in 2014, so it really shouldn't surprise anyone! Easier HP, and a lot lower profile!

Haha! We need that now, and we were only making a 'few mods'!

This late in the game, everyday is just another day! :-D
