Boost gauge recorded figures

[Filterlab]

I quickly plumbed in my Splitfire calibrated boost gauge this evening and went for a quick spin. I didn't bother mounting it in the dash as I don't want it permanently in the car, so I took a feed from the tree and routed the hose out of the bonnet and in the passenger window with enough length to hold it in my hand. :)

Measured (all at WOT):

1st: 5psi
2nd: 7psi
3rd, 4th and 5th: 8psi

Idle: 20 inHG
Overrun: 24 inHG

All in all I thought those figures were pretty good, especially the vacuum figures, certainly no leaks anywhere anyway. I have an MBC coming later in the week so I'll fit that and see what the effect is. I don't particularly want huge boost levels, but a slight overall increase and losing the artificially low 1st/2nd boost levels will be most welcome.

Any comments anyone?

you sure you've not missed a "1" off from in front of them PSI figures lol

Hehehehe, that'd be nice. ;) I won't be going quite that mad though!

What's your opinion on the vacuum figures mate?

What's your opinion on the vacuum figures mate?
pretty sure my vac figures were very close to that. But if i remember right i was getting a -0.02 reading on idle just before i took her off the road so might of had a small leak (could be the intercooler drain). Hopefully i'll get it working again soon & be able to have a look.

your positive boost figures are about right so don't think theirs anything wrong mate
