I thought cavitation occurred in water pumps?

Isnt dose the high pitched flutter? I thought flutter was the fff fff fft ffftt sound like a flap rapidly opening and closing which is what you usually hear in imports and 4.0Ls. ill be honest, im not fully sick just yet... |

Also fans and propellers can experience cavitation...

But isn't it only for liquids? IE when the impellor moves too fast and creates a low pressure area in the liquid, a void is formed in the liquid which then collapses on itself again. This void/collapse is the cavitation and the energy produced from this can cause pinholes/blowouts/corrosion to the impellor blades.
Gas would merely expand and reach really low pressures, thus avoiding cavitation. Wouldn't it? I'm happy to be corrected on this. PS Gir rocks! |

The term Dan meant is reversion, not cavitation.

–noun 1. the rapid formation and collapse of vapor pockets in a flowing liquid in regions of very low pressure, a frequent cause of structural damage to propellers, pumps, etc. I thought cavitation was when the liquid or gas was forced back through the turbine... Oops : :

every turbo vehicle?
VLT's don't have BOV's do they?

Even though i wouldn't do it to my car as the screamer pipe is good enough to let everyone know what's lurking, i think you might find using 2.5 inch pipework that is very short in total length may contribute. Having 3inch with a massive intake length will act as a plenum which inturn will cusion the pressure waves between the throttle plate and compressor. By the way whats a vlt, a vacant left testie?

Im not arguing that running no blow off valve will shorten the life of your turbo. Even if its not proven to help its better to spend $200 on a BOV just in case rather than rebuild a turbo. How is it not an extra thing to worry about though? If its not there then its not cant cause a boost leak hence you dont need to worry about it. Are you a professional?

I'm sorry if someone has already said this.... Or if I am terribly wrong.....
Not having a blow off valve causes the compressors airflow to 'back up' and build pressure to the point that it blasts back through the compressor inlet when the throttle plate closes.... right??? Now, wouldnt this cause the compressor wheel (and turbine wheel) to slow down rapidly??? I wouldnt think that this is very good, as you would probabarly be getting a brief, yet massive boost spike in your inlet manifold and intercooler piping (pre throttle body). Probabarly not the best thing to happen. Then you may have the issue of the massively hot exhaust gasses still trying to hammer past a temporarily stalled or slow moving turbine wheel. I'd say that this is not the healthiest thing to happen to one of these highly stressed components. With the spiking pressures in a system such as this, I would say that by leaving the BOV out of the system, you would also be generating extra heat throughout the system aswell. I may be completely wrong. Mike

Ok in your professional position, how many turbos have failed as a direct result of not using a blow off valve?
Which blow off valve would you recommend for a high boost app? Are all blow off valves created equal?
