Diesel racer!?
Is there any problem, adapting an external wastegate on a turbodiesel engine?
I know temperature is not a problem, diesel´s have lower egt´s... but diesel engines produce alot of particles,would that be a problem for the valve itself? Also alot of air goes trough them, would a 36mm wastegate be enough for a 2.0 liter diesel pumping 1,5 bar boost on a hybrid turbo? I know you guys are masters, you´ve helped alot a few years ago, so be kind to the newb... |
Re: Diesel racer!?
wastegate on a diesel? just run that ---- strait, just get bigger injectors. O0

Re: Diesel racer!?
a smaller wastegate would probably be just fine, as your probably getting a little inefficient at 1.5b-bar, the stock internal gate on my HY-35 wasnt all that big, and the actuator was supposed to open at something like 23psi IIRC.
36-38mm would be fine. but i agree, you dont need a wastegate >:D |
Re: Diesel racer!?
my diesel has no wastegate O0

Re: Diesel racer!?
Lol we wired the gate shut on dvst8r's D250 and with the free fuel mods the hx35 hits 50psi. Stock hg don't love that.

Re: Diesel racer!?
The John Deere tractor I use to mow with doesn't have a wastegate.
Unregulated boost FTW! |
Re: Diesel racer!?
My TDI golf doesn't have a waste gate.
Keep that mah shut and upgrade injectors. |
Re: Diesel racer!?
So what would exactly limit the boost? RPM´s? Exhaust/intake restricitons restriction?
That would be insane, it´s not intercooled(yet), wouldn´t the turbo be spining much faster? Heating up the air and oil? Your Vw tdi doesn´t have a wastegate? you´re kidding right? In europe all tdi´s have internal wastegates, or are VNT type... but they all have a electronic controlled type of mecanical actuator... either vacum or pressure actuated... |
Re: Diesel racer!?
Does it really matter if the intake air is hotter? Your not trying to prevent detonation with a diesel, detonation is what makes diesels work.
You want to watch your EGTs with a diesel. The richer you run it, the hotter they get. |

You want to watch your EGTs with a diesel. The richer you run it, the hotter they get. If your theory apply´s why almost every modern diesel is intercooled, and if you simply apply one to a non intercooled you get huge bhp gains? There are 2 versions of the engine in my car, a non intercooled with 90bhp, and 205nm and a intercooled version with 110bhp and 255nm... The only diference is the intercooler, the engine is exactly the same with diferent ECU map... |
