10 psi cruising at 75 mph

[hondarider552]

I cruise at 10psi at 75. Twins do have an effect on the different readings vs a VGT..

I like your avatar sorry for the off topic :rofl:

:yup: Oh and mine is around 5 too at 75.

Glad i could bring something to the table :rofl:

Gotta be a twin thing. I sit around 2 psi at 75. I would guess the 366 spools so easily with your lift and tires it has just enough load to produce some boost. Its a shame the small charger cant be bypassed at speed to help with economy.

That is exactly what i was thinking

 

[sweetdiesel]

Do you monitor drive press? And do you have a waste gate?

 

[cafryer]

Ya my drive psi is the same as boost and my wastegate is cranked all the way down

 

[baggedLB7]

Around five for me.

It is a twin thing. When I had twins, boost was at 10-12psi cruising at 75-80mph ish. With my single billet s366 with the t4, I can cruise at 90mph with like 5-6psi. I have 305/55/20s on the truck with no lift.
