Standard Boost On R33

[Promax]

Hey guys. I have got a couple of quick questions that I am hoping someone out there might be able to answer. I have an r33 that is basically stock, the only real mod is a 3 inch turbo back exhaust. My main question is what is the normal level that my car should be boosting to? I am fairly certain that standard boost should go up to 7psi. Yet I have never been able to get my car to boost past about 3.5-4psi (according to the standard gauge). Is this normal or could there be a problem with it? If so what are some of the likely reasons for my lack of boost? I am seriously starting to get over driving around with such little boost!

Thanks in advance

the "7 psi" is actually not psi, the 7 is measured in X100MMHG so 700 MMHG which is equal to about 14 psi. But if your gauge only goes to +3/4 it doesnt sound right.. 33's are stock 7/8/9 depending on mods (and my lvl of mental block) psi though so maybe it is right. 8 is just over half of 14 so i would expect about that on stock gauges i guess.When you get a chance, get under the bonnet, check the connections and if there all good, borrow or buy a boost gauge to check it out.

As mentioned, the guage is not in PSI, it is in mm/hg (x1000). 7psi would be just over the half way mark between 0 and 7 (works out to about 362mm/hg). So between the 3 or 4 mark on the standard guage would be about right.

Haha I alwayse just assumed it was PSI, dont I look like a dunce, oh well at least I know I am actually running proper boost levels (the needle usually gives a reading of just over half way). Thanks heaps for your help guys.
