Wastegate mod

[DJM]

Quick question on plugging off the wastegate do I need to plug off the wastegate too or just the Line?

[strokin_early_99]

Just the line is needed. It would not hurt to plug the wastegate just to keep the crud out of the hole.

What makes you say this.

Mine has been plugged for over a year now. With no problems at all.

Go get 'em Big. This I want to hear.

I'd like to hear this explanation as well.

Mine has been unplugged for probably 3 years or longer....

i talked to a diesel tech that works for my uncle at a kenworth dealer because i wanted to do that and he told me not to because i doesnt give u anymore power and it lets ur compressor wheel spin to fast and it will hurt it or something but what is the truth? i might be wrong so what is the benifet?

Disconnecting the wastegate line and plugging it does not allow the compressor wheel to spin faster.

What it does do is allow the turbo to build more boost. Your wheel will only spin as fast as the exhuast wheel drives the compressor wheel.

The advantages of disconnecting the wastegate line are faster spool up of the turbo, higher boost, quicker throttle response.

I have had mine disconnected and plugged for over a year, Abobb has had his disconnected for who knows how long. I know there are alot of members on this site that have been running this way for a long time as well. None of us have had any problems because of this line being disconnected and plugged.

I ran a banks big head for a long time and that will hold the wastegate closed longer than just unplugging it.

And more boost means spinning the turbo faster.

Yes but the compressor wheel will only spin as fast as the exhaust is pushing it.

From talking to many people about the stock turbo on the 7.3L it is my understanding that the stock turbo is good for 30 pounds of boost.
