The common misconception: The waste gate limits boost. Well it does, but for a reason...
The waste gate PROTECTS THE TURBO FROM OVERSPEED. That's it. This is "Turbo-101".
Boost pressure is directly related to compressor speed. If you overboost (particularly a stock turbo), you are also overspeeding it. That is why the wastegate is connected to, and senses boost pressure. When the pressure reaches a predetermined limit, the gate opens to control the pressure and LIMITS THE COMPRESSOR'S SPEED.
I always get a kick out of people trying to push the "TurboMaster" wastegate "controller". They're BS! You can't properly control the turbo (with a wastegate) if the gate is sensing exhaust back pressure (which the "TurboMaster" does). The proper method of wastegate control is by sensing Boost. End of story...
Goodnight, and don't forget to tip your waitress...
A fooler? eBay has some. Some electronic and one called BIGBOOST that plugs in to the vacuum lines. Beans has one similar to the BIGBOOST or around $50. I'd go with the BDP one. No electrical issues to worry about.
Well thanks for the info but I'm gunna give it a shot. Xtreme diesel has a new after market Turbo wheel, boost fooler and a banks waste gate actuater for about 250. And in my defense about the term "boost builder" I found several websites listing a boost builder for cummins duramax and stroker 6.0 but not a 7.3. I appreciate the feed back gents.
this is what your looking for it goes in the line going to your map sensor has to pop off valves, makes it take alittle more time for the waste gate to work
I went to the part store got a small air pressure regulator put a gauge on it hooked it to an air compressor set it at 17 pounds put it in the boost line going to the map sensor unhooked the waste gate plugged the line wired the waste gate shut makes 32 pounds of boost installed a ATS ported shroud compressor housing to stop the surge don't waste your money on a wheel pm if you want some pics or more info
dirtyboy is correct a wicked wheel is going to create less boost, more whistle. Also theres no such thing as a boost fooler...or builder...too much internet and ebay reading for some of you guys. If you want more boost get more fuel and more turbo..otherwise your pissing in the wind.
Heres a good boost fooler for you 45$ seems like a pretty good price. I made mine looks the same as that cost me like 35$ by the time I was done not including fuel to go find all the parts which cost an arm and a leg haha.
I think somebody said something about big boost heard they are crap idk just saying.
Can we please call it by its proper name Boost or Pressure regulator even Boost Fooler is in part properly descriptive. But it is not a boost builder!?! That is what a turbo or supercharger is. If anything the device in question is technically the opposite of said term i.e a boost limiter in function.
If we are talking a stock turbo anything past 25 psi is not only a waste but a negative for power and will kill your turbo much quicker. I think if you look at where the stock sensors limits boost and backpressure it tells the expected ratios. Look at where Ford/IH has the limits set on defueling from either the pressure readings MAP sensor (boost) or the EBPS ( drive pressure) it shows where the boost: drive ratios are at that point. 22 psi for boost and 28.8 drive pressure. As you go up from there in boost psi, drive psi skyrockets as both the turbine and compressor are outside their maps. IIRC 17psi boost is where its 1:1 ratio B.
