That is a question with NO real answer.
With WHAT for mods? What EM? What fuel? For what purpose will this vehicle be used? The VF30 will put out plenty of PSI.... |

If you have "Cobb tuning" then I guess it's up to them.

Seems that on the top end vf30s like to taper to 16-17 max psi.

The most I would run on pump gas is 18psi. On C16 I run 23 but it tapers to 18 by redline.

On 94 octane my EJ207, with pinks and VF30 peaks at 19.8 psi and holds that to redline, which was reduced to 7200 rpm due to maxed out injectors. I'm installing a Walbro 255 and Aeromotive FRP (plan to run + 0.5 bar fuel pressure) and water meth injection and hope to hit 22-24 psi, with a goal for 275+ lb/ft of torque.

There are are numerous posts on here with people making more than 300 who with VF30, which seems strange since it's rated for 33-36 lb/min of airflow which is roughly 350-370 hp at the crank. Peel off drivetrain losses and you barely scratch 300 whp. Maybe some turbos are capable of high pressure ratios (good wheel housing match), but the turbines some say are flow limited, so not sure how to push the compressor that hard.

Max boost is really subjective to your car, your mods, your fuel, your tune, your environmental aspects (elevations for instance) and a crap ton of other things. Figure somewhere between 15-20psi depending on all the factors and more listed |
