Standard Oil and Boost Guage questions..

[Gizmo73]

Hi Guys..

After searching the forums, i found some of the answers to my questions, but not all...

Background: R33 series 1, exhaust, TT, HKS pod filter, standard boost.. Just got it yesterday, and i love the drivability of it. A bit short on power and slower than my last car (modded LS1), but i think its more fun to drive !!

Anyway...

Boost Guage: I understand about the different measurements from psi to hmmmmm...(etc), however on the standard boost guage when is the car actually on boost ?? Is it when it reaches positive territory ?? What does the negative (-) readings mean ??

Also, if i dont plan on boosting the car, do i need a boost guage for diagnosis, or is the standard guage enough ??

Oil Guage: What are the standards ?? At idle, my pressure is a between 4 and 2, when driving around 60-70k's its between 4 and 6, and on the freeway doing 110-120 its always around 7. The previous owner used penzoil 10w-40, and next service im changing to the Motul.

Also, would an oil pressure guage be required, or are these pretty accurate ??

Thanks in advance guys...

When the needles above 0 the manifolds under positive pressure (over atmosphere), so yes its making boost from there on. The negative scale when just the intake vacuum, ie when its running like a normal N/A car...

Your better off buying an aftermaket boost gauge thou because the factory one is crap. Oil pressure seems about right...

what he said..

Once you increase the boost and things you should find its got a good amount of power. At stock boost its a bit slow.

Stock oil pressure guage is fine for street use, but you might want to look at an aftermarket oil pressure and/or oil temperature guage for track use.
