So whats the answers to the other questions in the above 2 posts?
the boot blow around 60psi.. waiting for my new 0-100 boost gauge this week..
So whats the answers to the other questions in the above 2 posts?
Shouldn't be blowing couplings off at 60psi. Are the edges of the pipe rolled? Try spraying some hairspray on the connection before slipping the coupling on. Acts like glue. Maybe get some better clamps too.
I just switched my setup to a 62/71/13 over a 80/96/1.32, and see about 20psi at 2000 rpm while brake boosting. You should be seeing something similar, or even better since you're running SXEs.
That doesn't answer his question about the pipes......
im gonna re-cap.
so you were running a 62/68 over a 75/83 and liked it.
should have spooled super fast
what were your boost and temp numbers?
now you are running a sxe 62 over an 80.
you do realize you went up 13mm on the turbine wheel and from a 1.1 to a 1.32housing right?
spool up is slower, the truck is quieter, and you blow boots off at 60psi but only have one boost gauge in the truck?
you didn't blow boots off before?
you have limited smoke under brisk acceleration
is the 80 suppose to spool faster? absolutely not. its lots bigger, in all 3 categories.
if indeed you are having an issue my bestist guess if you have messed with your fueling during the change, maybe a dirty fuel filter? what is fuel pressure at the IP? But I bet you you are just struggling with a 600 hp truck that has a primary that can do over 1k. its gonna drive poorly.
that's very low total boost for a small set of compounds. your secondary is making like 3 lbs.
what is the fuel pressure? lift pump happen to die in the midst of all this and the pump/ pumps are starving for fuel? If it isn't blacking out the sky with low boost, it isn't there to burn and make boost/ power.
