hey guys
Hey I have a 2001 2500 and i have read here about how you can close the wastegate or something and it helps with power, Am i reading things wrong here? what can i do with it and what is it realy for oh does my truck even have a wastegate and where would it be and how can i adjust it if i had to?

thanks

 

auto or manual?

 

the wastegate basically limits the amount of boost u can build. You can plug or pinch the line to up boost, and my wastegate has a bolt type thing that u can open or close to adjust how much boost u want to limit. It will be connected right by the turbo.

 

it is a auto. under the turbo

 

Do a search on turnbuckle or j-hook, you'll find lots of pictures and threads on it. This is your only option on a stock turbo, auto, 01-02 truck.

 

does it not mess up somthing by keeping the wastegate closed all the time? why do they put one on if it does not?

 

More boost won't give you more power.If you clear up the smoke WOT and you don't have to let off for EGT reasons you have enough boost. If you run more boost than necessary you'll need more energy to compress air unnecessarily and this energy will not be available at the crankshaft...
Keeping the WG closed all the time can be bad juju if you overspool the turbo-it will throw lots of pieces. Any more than 30-35 psi is far out of the efficiency map of the stock turbo, and will net less hp and higher EGTs..

ok well if it is not going to give me more power then why would i want to do it right?

 

You might want to do it because your EGTs are too high and you have to let off for that reason. Moderately higher boost than the stock 21 psi will help you cool EGTs.

 

What kind of Boost are u getting right now at WOT? 15-20? 25-30? you should do the j-hook for now, because if ur only seeing around 20psi or so, the extra 10 psi is a whole other level, it's some fun power up there.

When I had the stock auto I could barely hit 18psi. When I did the 100 plate I re-clamped the boost line to the barb fitting(didn't plug or pinch it) just tightened things up, and now with the 5spd I can hit 30psi easily, probably more I haven't held WOT for to long yet, and the thing just flys. I think the banks housing and wastgate help over stock, but once 30 psi hit's you really can't believe it's the same truck.

 

with all my mods i have 28psi im ordering the j-hook from tst and im hoping for 35 or more psi...lookin at my mods what do yall think the increase will be i know it wont be much but i hope it will help to cool egts cuz i jump to 1500* very very quick in wot

 

is ur straight exhaust 4" or the stock pipe? ^

 

stock pipe but i have plans for the 4" turbo back

 

out of a HY35/9???

 

you should beable to git 35 psi
I can git 38 psi with my mods and cant even hit 1200*
