If you haven't already you may want to check out Engineering Explained.

He isnt bad, but he is just a student, so he yaps about what he learnt in class. High detail, but not really good for people who just need to learn the concepts.

JobeMinacum Honda has this add-on called vtec ,I heard it chops your grass quicker than a turbo

The TD42 found in Nissan patrol (aka safari) is a mechanically injected engine in which the the amount of fuel injected per cycle is based on only throttle position. This is cool because aside from the glow plugs needed to cold start the motor it doesn't need any electronics (only the ti version even had any). On the other hand when you combine this with the fact the TD42 (like most factory diesels) is a lean burn engine (more air than required to burn the fuel charge) it means without additional adjustment or modification increasing boost pressures will not have a positive effect on power output, instead more power can be made at the same boost with just a fuel pump adjustment, just at the expense of higher exhaust gas temperatures and more smoke when the throttle pedal is fully depressed before full boost is reached.

a cold atart is whem you dont glow it. the glow plugs just heat up a bit of diesel in the block. people think it doesnt do much but if you cold start (colder areas like where i live) it does a lot of damage to the motor and also eats up alot of oil. whitr smoke is oil burning and black smoke is it running to rich. if you go more boost you need more fuel so you turn the injector pump up a little. go to much power youll be upgrading intake and exhaust. my gu just has a stock turbo on 12psi with a 3" straight through that dumps behind the cab. that does the job for now

Turning up boost pressure will always increase the energy yield from fuel. This is why modern engines have higher compression ratios. Same/same. Also increasing the amount of available air to burn the fuel increases the speed of the burn, which in turn raises the power slightly. So turning up boost pressure on a diesel will have a positive effect without adjusting the fuel

Yes I know that😝

Mike LeBlanc it's just a screw that blocks the airflow between the inlet and outlet. You loosen the screw to let more air flow, or run it down to block air flow. Blocking airflow increases boost, and loosening it decreases boost.

Or wait..no that's backward. Loosen the screw to bleed off air and keep the wastegate open, and tighten it to close the wastegate. Either way, it's still a T with a screw. Look up homemade bleed valves on KZfaq for more info

exactly what i thought

I thought it was a subaru turbo with that janky ass flange

Variable vane

npbevo thanks for the correction troll

Wow, ungrateful

Haha this made my day and is very true. Maby its just over some people's heads. since you haven't gotten any likes

Agreed

The VW 1.8t are easy to tune via OBD. Just go to your local tuner.

Yeah I know, I just wanted to know if there was some way to trick the N75.. Maybe if you put it in between the turbo and the N75?

You could put it between N75 and turbo to get a higher boost pressure, but the ECU would sense overpressure and would throw fault codes. Even if it didn´t you would still have to get it tuned, so you are not running lean

That's what I thought.. Was just curious, currently I'm building a new engine for my Audi A3 with a GT2871, Tial wastegate, bigger injectors and stuff like that, so it's not something I'm gonna do anyways 😂

That is where the restrictor plays a role and it is so minimal that will not matter on a MAF or even less than nothing on speed density setups. I run one on 1.8t and it's awesome.

no it wouldnt because the valve is venting air that wouldnt be going into the engine the engine anyway it just goes straight to the actuator.

who cares? it´s a turbo and it shows what is should show :P

u win

Pfft. Leaking half a cc of air?

Yeah, the small amount of lost air isn't going to make boost build slower. The fact that the video shows the wastegate partially opening under less than target boost, that will though.

Ball and spring just lets you plumb it into the cabin without having to hear it whistle. That's what I did anyway.
