Because the intake is a different design that is easier to modify so I can run an intercooler.
The turbo is also a different trim so I can move the powerband around a bit if need be, until I have the money for a mechanical variable turbo setup.

Does the truck smoke at all now? It should give a small puff when you first get on it, then be fairly clear afterwards for a stock setup. If you aren't getting any smoke, then yes the ALDA is probably blown.
Even with lower gearing, you should be able to load the engine enough to build boost, especially in higher gears.
Have you looked over the exhaust to make sure it doesn't have any kinks or crimps? What type of muffler are you running?

You have some sweet turbos and have done some extensive and admirable mods to your rigs, but you still don't have a clue how a turbine works; I recall when you were banned from a site for continuing to vociferously spread this misinformation.

FYI, I have a Mechanical Engineering degree, I'm licenced to practice professionally, and I've run this firm for seven years.

For others who wish to actually educate themselves about turbomachinery, the most accessible information is at http://en.wikipedia.org/wiki/Turbocharger which will then link you to http://en.wikipedia.org/wiki/Turbine I will not be commenting further on this (turbo operation) topic.

To reiterate to the OP: your ALDA capsule may be ruptured. It only takes about 10 seconds to remove it (for performance verification) if you have the proper (27 and 30mm?) "service" (really thin heads, typically used for hydraulic line work) wrenches.

can you point out in either of those sites you mentioned where it contradicts FI's (and my own) opinion of pressure, not heat making a turbo work?

Im on the pressure not heat deal to, had a little rear mount setup on my cavalier and after about 10 feet of pipe it was still spun well enough to have very little lag and still make 12 lbs.. um.. pressure differential across the turbine causes flow and yes if it is hotter and therefore less dense the same mass with fill a larger area causing a greater pressure differential but... heat itself does not turn the turbo

Can we just say, the spent fuel combusted inside the cylinder drives the Turbo?

The Exhaust, is the by-product from the fuel, which produces Heat. If there is no Heat, then there is no use having a Pyrometer.

I for one, is not going to place my hand in front of the exhaust manifold to see which is coning out.

I have corrected the misinformation you posted.

Also incorrect, it was for debating with poorly educated people that have no clue what their talking about who also refuse to understand actual science.

That only proves anyone can earn a "licence".

Even the closest thing to a true "heat engine", the Stirling, also works on pressure and flow alone.

Another run away tactic. Please people, if you're unwilling to back your position, its best not to say anything in the first place. Running away only shows complete flaccidity in a debate, especially when using the single post "hit-n-run" method.
This is how people like that appear to everyone else:


Incorrect. A failed ALDA will only show as low power and slushy throttle response. Low boost is not a symptom of a failed ALDA.

No, that would be conceding to somebody posting false information.

Which is not what drives the turbo.

Why, afraid you'd feel the mass, velocity and volume of the exhaust?
