Tip turbine boost?


Recommended Posts

Going to add a boost gauge to my truck (1980 , 350 econodyne) Plan is to put a collar in the crossover pipe from the turbo to the top turbine but before I do that thought I would ask if there is provisions somewhere for that already that I don’t see.

Use a port on your intake manifold for boost gauge line.

Yes, that is my question, is there a port somewhere already that I have not noticed or do I have to add one. It appears that the title of this thread has caused some confusion. I only mentioned the tip turbine because, of course, the entire intake system between the turbo and head is unique to this system and it is so where in that system that a port will be if one already exists.

Not to up on that era Mack stuff, but I always liked the Tip-Turbine set-up. A better solution than Cummins low-flow cooling, for the same problem. How do you aftercool better than engine coolant can? How do you do it and fit the engine into current vehicles without re-designing the front end? Cat didn't try, Cummins tried to "super-cool" the coolant before it entered the engine, Mack decided to pull air from outside the hood, to pass through an air to air inside the hood.

If the puff limiter works and is shimmed correctly, it should have minimal smoke and run about as good as it's gonna run.  That "gizmo"  would have got air when the parking brakes were released and then it would regulate the rack's travel according to manifold pressure.  Over fueling is never good. Looks cool when you're 23 or so..... then when you pay for it a couple times, not so cool.

The boosted intake air is what he is trying to measure, it just so happens to be a tip turbine engine. Although I wonder how much pressure is bled off from the turbo for the tip turbine system. 

In my head I've always thought the puff limiter was for drivers who didn't own the truck. When you pay the bills you are more conscious about what is coming out the stack and what's going past the rings into your crankcase. Wait until you feel the turbo come up then start adding fuel

If done well, there is no disadvantage to making automatic. Most Mfg did, some better than others.  I never had a problem with either Cummins (AFC) or Cats method. Earlier methods by all mfg needed some work.

 I wouldn't want to have to monitor the boost at all times to have a good running engine. 

 I can think of no advantage to not having the system take care of itself. All of them were adjustable if you knew how.

This thread makes no sense  to me is he talking about the tip turbine or the main engine turbo?

I apologize for the confusion. Yesterday I posted “It appears that the title of this thread has caused some confusion. I only mentioned the tip turbine because, of course, the entire intake system between the turbo and head is unique to this system and it is so where in that system that a port will be if one already exists.” To try to clear it up but let me say, this is not about the tip turbine it is about finding a good signal source for a boost gauge.
