I would not go over 1,0-1,2bar. It's so tiny.

i run 25 psi all the time..

its seen spikes of 40, and also exploded an engine block at ~40 psi...

they may be a tiny turbo, but they flow awesome (for what they are) and have hardly any lag..

Oh, I thought you said 1749vb somewhere in past. Both 1749v and vnt15 is used in ALH (90hp)and AFN (110hp).

I've tuned a T4 recently with a VNT15 fitted. They're tiny.

When I saw it I said - "has barbie lost her hairdryer"

I struggled to get 15 psi, but the owner wouldn't let me turn the fuel up anymore because it was "getting a bit smoky"  ::)

mine only makes smoke off the bottom end, and thats probably because of my n/a inj pump..

i make 20 psi if i really wanna hold some RPMs. i usually dont push it anymore than 15psi most of the time..

i dont have my fueling turned up that much tho. i have alot of screw left. i dont have a collar on my fuel screw, but its not much past where the collar would be..

just shy of 3 bar..

if you run the VNT up that high tho, it will only be a matter of time before it grenades..
