That's not necessary true that the car's parts can't handle the extra power. Just because they set the boost low, doesn't mean the rear end, clutch, engine internals or transmission can't handle more power than what the car comes with. And Tuners like Lingenfelter ,Hennessey, APR, GIAC ect... do a lot of R&D on these cars to determine what they can actually handle over long periods of time.
I see their point in a way, but how likely is it that whatever is wrong with your car is a result of the ECU Tune or Piggy Back? They often use that as the excuse to void your warranty when it was never the cause.
How is an ecu software map more money? It's a porgram of inputs.
so an injector flowing at 50% duty cycle lasts longer than one flowing at 80% duty cycle?
a turbo allowed by the wastegate to make 15 lbs instead of 11 will die sooner?
Some engine tuners will tell you that if your car has a duty cycle of 80%, you have a possible gain of 20%. However, the injector is an electronic solenoid and cannot be held open for too long or it will overheat and fail.
Brian, study engineering, then tell me that's not how it works. Fatigue is a real thing, and there are people who will spend an entire PhD studying it.
Another example:
G forces. An average sneeze generates about 2.9 G's and you are barely affected. Yet, that amount of positive G force experienced for a minute, and you would undoubtedly pass out.
A good example would be Renewal Windows by Anderson ...They are built to withstand extreme temperatures but the company knows 999/1000 they will be installed in places that don't come anywhere near what they can handle.
Compressing air generates heat; ie, the more you compress air, the more heat you generate. Also, that 15 psi is pushing on the compressor wheel in the opposite direction of the compressor outlet, which means the shaft is being pushed against the bearing/seal. So, the extra rpm is not the only thing to worry about.I understand your mechanical points... but I don't think they are real-world valid for increasing boost.
a spoiled turbo is going to spin nearly the same way it would if it was gated at 11 or 15 psi (real life, what my flash changed). so yes, it will spin a little faster if it's not getting bled off... but when you're already spinning 100,000-150,000 rpms, is there really a LIFE difference if you go a few more k?
Does a turbo have a revolution counter on it? usually it's the seals that go. the seals don't do any work. The heat difference at those speeds is 'negligent' because it's absurd at all rpms. If anything, it's the oil that fails to do it's job.
My point is that the parts are designed to handle more power in order to increase longevity. Increasing power over stock decreases longevity.I think we can all agree that increasing power can put extra stress on car parts causing them to wear out faster. At what rate, I'm not sure. My point is these parts are built to handle more power than what cars come with. Will it wear out faster? Probably. Will it be detrimental to the car? Most likely not unless you are abusing the car 24/7 non stop.
