my stock hx suppours 425, not sure how long it will.

 

I think he is talk as a DD/tow rig. I would say at best a 35/40 will support 375 as a tow rig. My HX35 with a non wastegated 14cm housing made 427/1006 with EGT at 1500+ not to hot but not good for a DD the 35/40 is issue is shaft failer due to surging or over boosting the thing. Ive been in one when it broke. Not a nice noise.

392hemiX are you in run it till it breaks then fix it right mode or keep it the same way for a long time mode if its the first option then not over 17* timing and 50psi the second option id say 16* and 40-45 psi

Beets whats your boost at?

 

c'mon joe the burban needs twins!

 

I do hear you but I can't because my internet is down. I can't make any calls. and my truck is to slow.

 

my waste gate is plugged i try to keep it under 40 but have hit 53lbs
The truck is my dd/tow rig/work truck/toy right now it is my only running transportation so i have to take it easy

 

I got the 60 pound springs, 4000 gsk, and the rack plug.

Now we will see what happens.

thanks for the help everyone.

 

waiting patiently to hear how she runs

 

All is well axept the truck still need work but it is running.

Anyhow the rack plug makes a little difference near wot. I thought it would be more but it is doing its job. It did give me lets say about 2% gain. It does pull harder at wot.

The 4000 gsk did give me more rpm and more power though the whole rpm. You will gain more power of the line and through the rpm over the 3000 gsk.

It feels like 3-5% difference. Not much but you can tell it is more over the 3000....

more ? ask away...
