I'm gonna be pulling off the downpipe to fix an oil leak, I wonder what opinions are on putting on a heat shield like this one:

I've got one of the M7 heat shields, and have had no issues with it for almost a year.

I'm just asking opinions if I should just be happy with my setup, or if there is something better while I'm into that area of the car. My car is a daily driver, no plans for track use.

I figure that I'm OK with my setup (factory heat shield remains in place), but wanted to see what others thought.

Thanks,
Mike

 

I have the Way turbo wrap. It keeps the heat in the hot side of the turbocharger, where it needs to be and away from the bearing and the compressor side of the turbo, where you don't want heat. The insulation is almost completely covered by the OEM heat shield.

I work on industrial diesels, all the turbo diesels I see have the hot sides of their turbos wrapped with insulation.

I have the Way turbo wrap also. Huge difference on bonnet temps, much much cooler. If the bonnet temp is lower, everything under bonnet temps must be lower too.

 

Dave hit the nail on the head.

Those big heat shields that g over the full width of the turbo are trapping heat where it shouldn't be. Letting the bearing and cold side get soaked in heat.

A wrap or blanket that only covers the hot side is doing all the good without the negative. Keeping heat inside the hot side where hotter is better for the turbo working efficiently. But not trapping heat over the bearing to cook the oil, and over the cold side to raise your intake temps(which you want low).

The factory heat shield does not cover the entire turbo, and that's not an accident. Not sure how companies like M7 justify their designs that bolt on inches above the turbo and go the full width of it.
