Griffin951

I have a 86 951 and the gage is saying im pushing almost 2 bars which is about 28 lbs. i know stock is 11 and i need ideas on what to do so i don't do any damage also i was told that there is a stage 2 chip set in it from the previous owner if that makes a difference

Hehe, the gauge reads pretty poorly on the dash.

Get an additional boost gauge and that will give you the true reading.

So im guessing if i actually was pushing 20+ my car woulda blown already and where could i get a new gauge

1.75 bar is normal

Griffin951

Im new to porsche stuff and if 1.75 is normal what is it actually pushing

The gauge reads Armo+boost. You're only really seeing 14 at most. Probably closer to 11 or 12. And yeah... not always spot on either.

Griffin951

whats Armo and would a chip set bump it up the boost alittle

GAH! My phone. Atmo as in atmospheric...

Griffin951

hahaha o ok thanks

yes you will not actually be into boost until you see the factory gauge at one bar. 20psi and you would notice a huge difference in power but i doubt the factory wastegate would allow it.

Aftermarket/reburned chips are designed to remove the overboost protection and remap fuel etc. I have chips for stock turbo, 16 pounds iirc. I'd have to get details on the rest of the specs. I have them somewhere. Never got a chance to install them

ill have to crack open my car and see what kind of chip sets are in it, who sells good chipsets

New to 944 go here for some very solid info: http://www.clarks-garage.com/

944 obscene is correct. to help understand it: assume armo is just a a typo for atmo for atmosphere (atm). 1 atmosphere = ~14.7 psi (at sea level) which is the ambient air pressure we live and breathe in.

1.75 bar = 1.73 atm = 25.38 psi-14.7=10.68 psi boost over ambient
