Unhappy Poor little stock turbo :(

So I've got a stock turbo on here temporarily while I wait on a 38r to get here. This is with DI mini-me's. When you floor it, it'll get to a certain point and then actually bog down until you let your foot out of it. If you ease up on it it'll start going fast again.

Now I realize the poor thing isn't made to run with these injectors, but what is actually happening to the turbo that makes the truck slow down when more fuel is applied? I can understand it getting to a point where it won't make any more power, but what causes it to make less?

Re: Poor little stock turbo :(

It sounds like you are dumping SO MUCH fuel, you are actually flooding the combustion process. Like spraying too much water, instead of enhancing the burn, you are in effect dousing it.
By easing out of the loud pedal, you make the air/fuel mixture much more combustible.

At least thats my theory.

Thats just plain mean.... how could you do that to a poor little turbo? What #s are to seeing?...... just tie the wastegate shut.... and put some kind of strong screen in your IC pipes to prevent turbo shrapnel from entering..... I want to see some turbo carnage.

Re: Poor little stock turbo :(

When I had to run the stocker while waiting for the TN BB, the stocker would surge so bad it would stall completely... Kinda fun to play with... But I would go for too much fuel putting out the flame.

Re: Poor little stock turbo :(

I've seen boost and egt both drop with very large injectors and too much pedal too fast. Not in my truck of course with it's cute little B's.

You can definately drown one in diesel fuel.
