If I've picked it up right I'm thinking that 20psi at ten degrees will give the same performance regardless of turbo so psi is pretty much irrelevant for comparative performance potential unless the inlet temperature is known. 24psi with a good front mount should make more power than 24psi with a top mount (assuming it's a small turbo working hard) as the inlet temp should be lower but this is probably around the point where any more boost could actually drop performance as the inlet temperature will rocket, cancelling any gains.
Is there any information anywhere on the maximum inlet temperatures that can be run safely?
It also pointed out that diesels are accelerated by adding fuel rather than air like petrol engines (which is what I'm used to) so I had a bit of a 'lightbulb switching on' moment over the whole diesel tuning/ fuel/ boost thing works. Now I have the process in the right order the whole thing makes far more sense.
Thanks Silverzx
No problem dude! Glad its clicked.
The rep systems there for a reason.
