Hello all. Still working on the Hallet. Getting closer to getting it to run but having trouble controlling the boost. Anything over 10pounds and it detonates. The current way of boost control is the springs in the intercooler runners. I have yet to find anybody who can explain how this system works. Either way I have tried it with both the strongest and lightest springs. No change to speak of. Does anybody have any way of installing a manual Westgate on this type system. I appreciate the help. Call if you want to discuss. Jack 559-392-6444

Gale Banks made some exhaust risers with provisions for waste gates, although they may not be as common as all of the ones he made without any provisions. I have a set of them, probably taller than what you have with your PFM system.

Those early systems used a bypass hole drilled in the turbo exhaust housing to limit the amount of boost they would make. The actual waste gate would improve bottom end performance quite a bit over the large bypass hole in the housing.

Got your PM Wheeler. Thanks much. I would very much look forward to hearing from you when you get your hands on those parts. Regarding the Ford comment; don't give it a thought. Out of all my old car and old boat friends, I am the only one willing to run a ford. Not everyone can have good taste ya know. Have a great day.

Here are some better pix of the pieces I made.

The adapters that I purchased are 1 7/16 thick, the waste gate bolt spacing is 2 7/8 and the flange for turbo is 2 3/4 by 3 1/4.

Hope this helps.
Those are some nice pieces. Very nice job of building those. :))THumbsUp

Acespack (the OP) expressed interest in them, I'll let you know what he decides. :))THumbsUp

Damn Barry! did you really think that I've been a dumb drywaller all my life?
Bob was probably asking about the custom welded ones you did.

So you have a tig welder stashed someplace?

It's nothing special, just a .060 over 454 with an old school PFM system.

I purchased the boat with turbos missing and it looked like this ...

I didn't want to deal with mounting the new Tubonetics that I bought so I bought a blower ...

I brought the blower home and then decided I didn't want to deal with tearing the engine apart so I traded off the blower for this ....

I mocked up the Gentry system then decided that I didn't like the carbs so close to the back seat so I decided to make the PFM system work with the new turbos ....

I either have no time or no money so the boat just sits in the hangar with a bunch of junk piled around it ... :indifferent0001:

My boat 005_1.jpg

This is where it's at today ....

I hope to get back to work on it soon, if time permits. :wink2:

There's a nice Thermal Dynamics at my brothers shop back in the Oc.

I made the parts for the turbos and tacked 'em up then had a friend do the welding as I refuse to wear reading glasses. :redface:

Now that I think about it I do have a torch for my old Miller out at the ranch, no cooling tank though. :duh:


Who's Bob? is Bob the person who started this thread?

it should not detonate at slightly over 10 psi in my opinion.(if everything is o.k). got a pic? sounds like makeshift blow off valve in runners. what is your timing set at wot(wide open throttle)? what is the compression ratio? what fuel,pump gas 91? one more thing, are you sure you are not running lean? could be too much timing & running too lean? my banks set-up ran 13 psi on pump gas for years.

Timing is set at 30 pinned. I have a boost retard set at 1.5 per pound. Still working on carb. Stepped up a couple of jet sizes yesterday and it felt better; but once I get to 5,000 the boost climbs well over 12lbs and it detonates. I'm working on putting together a waste gate system as we speak. Once the boost is controlled I can dial in the fuel and timing a bit better.
My static CR is 8.1 on 91oc fuel, 13lbs is probably a bit much; at least from what I am being told.The odd thing is when running around 4,800 rpm but keeping the boost around 7lbs; after a few minuets the motor just starts to back out. Like running out of fuel or the ignition system is not keeping up.
Fuel pressure and bowl level are 25% of the glass, so I know it isn't running out of fuel. It is also kind of inconsistent as to when it happens. Anyway, just throwing it out there. Until I get the other issues delt with; I can't move forward.
