they guy i bought my truck from said id need 2 get a new wastegate because the one on it is fully closed. why whould he do that? and will it hurt it?

 

if the wastegate is closed that aint a bad thing you will run higher boost but if you dont have a boost guage i would tone it down

 

alright just wanted 2 make sure. thanks you guys have been a big help

 

i am running a turbo that doesnt even have a wastegate on it

 

true it will run higher boost ... but have you checked your drive press lately? high drive press is not a good thing

 

if its a stock turbo i wouldnt be worried about it, depending on if he has any fueling upgrades

 

if its a stock turbo thats even more reason to worry bout it, smaller tighter housing restricts flow and raises drive press resulting in a loss of power. but it looks cool to see the boost guage higher than it was so its worth it right?

 

 

Yea.....Not a good thing, We restrict flow to the wastegate, But we dont block it off. THE WASTE GATE MUST OPEN SOME!!! Not to mention, With your waste gate not functioning your probably loosing quite a bit of power. With any mods to the truck you would already be out of the efficiency range of the turbo and simply trying to compress hot useless air. Not to mention that your asking for disaster when you over spool the charger, It's only a matter of time before it pops.

So with that said , You guys with aftermarket chargers reading this. THERE IS MORE TO ADJUSTING YOU WASTEGATE than just more boost. Before making any adjustments know the Map of the charger and the max efficent boost!

.....I didnt read this when i posted my first post.....High drive pressures.....they eat head gaskets, pistons and lots of other parts you need to remain running....Avoid them at all cost....
