Turbo BS Thread

my truck goes in "open loop decel" according to torque pro and uses basically no fuel. it does this instantly from what ive seen.

 

The reason for being rich after open to closed throttle is because you are suddenly changing the amount of air in the engine (reducing it) and because there is suddenly less air there is effectively more fuel for the lesser amount of air causing a rich condition until the excess fuel is burned and a stable AFR is achieved. This is especially common for turbocharged vehicles when they have to add more fuel (over 14.7:1) and let off the throttle while in boost.

 

Mine does too

 

And the tape comes off

 

roll tide man!

 

Pretty billet under there. What size turbo?

 

The tag says 58/58? I got what Luis recommended. But not exactly positive because there’s a casting on the exhaust part that says 68

 

Unless I’m reading that wrong?

 

Nice that will be fun. Bb or journal?

 

That sucker can make 400hp pump gas

 

Luis said with my fuel mods this turbo could make around 700 for a 3rz most but without building my motor or trans swap I’ll keep it around 300ish for now

 

Would leaded racing fuel have an adverse affect on fuel injectors ?

 

Heck yeah. Engine would need love for 700.

 

Could a MAP-ECU3 control the solenoid on a Holset HE351 ?

Edit: this is “electronic boost control” (EBC) ?

 

The MAP-ECU3 does support EBC. Whether or not it will work with the Holset will depend on the signal that the Holset is looking for. The MAP-ECU3 provides a switched switched output that acts as a switched ground, so one side of the Holset would be power and the other would connect to the MAP-ECU3 for the ground. In the software, you configure duty cycle, gain, sensitivity, and target boost. The MAP-ECU3 also supports launch control and flat foot shifting.

 

EBC is VGT Actuator, right? Or am I completely wrong lol

 

... Am i missing something? Ebc for your supercharger? @05Taco4x4

 

EBC is typically a solenoid that bleeds pressure so the wastegate doesn't open as soon allowing you to build more boost. VGT is variable geometry turbos change the turbine wheel allowing you to control how fast the turbo spools. Theoretically, it should be possible to control boost to an extent with the VGT but an actual boost controller and wastegate would probably work better.

 

The Holset he's asking about is a turbo off a Cummins diesel. Maybe he's trying to dual charge???

 

Sometimes i hate being the cute one in the group... It seems like everyone in here has a plethora (sometimes it seems like an unlimited amount) of boost knowlege. Good group of guys we got here, glad to be a part
