waste gate
is it ok to plug off the hose that gose to the wast gate?? build more boost?? some guy told me to do that. dk if it will hurt my truck any

running lean will cause heat. watch egt's
|
Use an ajustable boost elbow. The wastegate protects your turbo.
|
Or you could do what I do with no wastegate at all - which is watch my boost and EGT gauges very carefully. But I'd recommend an adjustable boost elbow, too.

did it on my friends 12v with a hx35/40 hyb, egt were 1200-1300 at manifold, added a little more fuel and cooled it right down:tttt:

too rich or too lean will build too much heat. This is true no matter what sort of engine or which sort of fuel. There is always an acceptable range for every setup, it is usually just figuring out the right range.

You can only have as much air as combustion can drive the charger. If you are short on fuel the charger can not really overbuild boost in a properly matched set up. Now, you can have excessive EGTs from running a turbo outside of its map, or efficiency zone, and the high EGTs are from the excessively hot intake charge at the engine.
The point of the wastegate is to bypass the turbine to control turbine speed and thus, boost pressure, so the charge doesn't overspeed or create too much heat. Overspeeding the charger can cause high EGTs, excessive turbo bearing wear, and ultimately, turbo failure. On an HX 35 we like to see about 36lbs of boost. anything more than that it makes more heat than the intercooler can effectively cope with and you gain nothing. If you need more air than that you need a bigger charger. Use the adjustable boost elbow. |
