Engine/Transmission (1998.5 - 2002) Boost pressre and EGT

[RClark]

Will raising the boost pressure reduce or contain EGT's? new injectors gave me more power but stock boost went up 3 psi and EGT's went to 1250-1300 at max load.

if I raise the boost pressure to 26-28 psi what will happen?

It is a stock turbo, new that Dodge just installed about 1000 miles ago.

Can go to 30# if you want. Will probably need a boost fooler, so the computer won't throw a code.

From my experientation, it just really depends and there seems to be alot of variables.



If you are more interested, READ some of this. From what I could figure out, if you can use more air it helps. If not, it don't.

if it the stock turbo then it is the hy? Mine has been on a down hill slide lately and I just found a hx-35 from a manual that should be good for 40 psi or so. The hy is too restrictive get rid of it!

My HY didn't last too long making 40LBS of boost



Only 3 more psi?? You haven't blocked off the wastegate huh?

An HX 35 should be wastegated to no more than about 35 psi. Above that it over heats the charge air & defeats the purpose.
