Turbocharging 101 – Wastegate Basics

Here we see what should not be done on an internal wastegate setup, which ultimately lead to the customers engine blowing from overboosting

lmao
wow.
i live in nc and there are some dumb as people down here.
Acosta Motorports in NJ……
who the fuck would even do that?
Even with the rong backing on the turbo the wastegate would have still opend and only caused a slow boost creep at higher rpm. The driver should have been able to detect this via gauge or “seat of the pants feel” If your going to drive a modified turbo car you should atleast know some basics.
wouldnt whoever did that know to just run an external gate? the guy must have been drunk when he was working on the car lol
I have just the same turbo on nissan D21 2.3 Diesel
when u customise waste gate u also need 2 customise your dump pipe
wow i hope u didnt have to pay for there mistake!! lol i bet the guy who did that is havn fun finding a new job! and embarassed!! lol
what a fuck up, anyone who does something like that should not even be alowed to work n weed wackers!
damn, how dumb can people get.
yes, well it caused the guy to blow his motor, and then blow both turbos, so yes, it was very expensive for him. Unfortunately, the customer didnt persue legal action against MVA.
Was the company that did the modifiaction not at fault? damnn thats an expensive mess!
They are the factory R33 outlets, with a flange welded directly to it. Good old MVA in NJ did this master peice and wasted about $15,000 in repairs for the guy.
Nice. I bet the thing was “super fast” right before it blew up.
I call them intergral wastegates,as they are part of the exhaust housing. Intergral with them.
What did that outlet tube come from ? Looks like a Nissan piece.
well… this set up isnt really that bad, simple solution… install an external wastegate, i mean honestly, you dont need the internal wastegate, it would be the same as weilding it back up, but then again, i supposed it depends on what the rest of the setup on the car is like eg is the flange set up so you can put an external on
Wow thats crazy. I would be pissed if that happened to me. Good video
Some thing doesn’t sound right here. A shop fucks up your car and you won’t reveal who it is? 1 star.
It does not need much to bleed pressure yes. But the more the engine flows the more it needs to open. Take a BOV as an example. You wouldnt want to put a tiny bov meant to flow a 1.5 liter 4 banger on a 6 liter V8 turbo, I bet you will be having a hard time venting it. Same with wastegates. You want it to vent asap not just a bit over what it needs to.
hahah if these idiots did realise that when they put it on they should not b working on cars fullstop!.!.!
dont seem to be rude but thats wak .. ide never go to that shop again .
ide also be ask for my money back .
props for doin a good cut
Looks in that vid that the waste gate was still opening. It doesn’t need to open much to bleed off drive pressure.
Either way, if the turbo was only good to 35psi and it was hitting 50psi… that should have be an indicator that something wasn’t right!
no, the wastegate releases unwanted extra air from the turbo, if it didn’t had a waste gate you wouldn’t have control over the amount of PSI you want the turbo to deliver. Not good because pressure would just keep rising and rising as long as you keep revving up.
A dump valve or blowoff valve, releases air pressure in the intake when you let go of the gas so that the same pressure doesnt goo back at the turbo and stop the turbo compressor blades from spinning.
There you go!
good video, although you should’ve gotten an assistant to help you with holding the components.
