My former corpse '83 244ti is ready for more boost. It's up to all 'stage 0' standards, and begging for more. I just finished installing the intercooler today, and it works great. I figure with the intercooler plus my straightpipe, I can run around 11psi with 93 octane without problems. Does this sound reasonable?

Anyways, tomorrow I plan on calibrating the stock guage with a pressure guage I'll tee into a line. I'm going to just mark it off throughout the yellow and red zones, one mark per PSI. Just to be sure it's accurate though, I'd like to know what the stock black-yellow-red guage is actually displaying. I'm thinking in terms of a clock. At stock boost, my guage goes a little past 12, or halfway into the yellow. This should be 5.5-6psi to my knowledge. What is the actual boost at 1, 2, 3, 4, 5 o'clock? thanks for the help guys. Hopefully if I can get the right figures I'll avoid broken rods and sending my project back to the graveyard.

You're doing the smart thing,IMHO, calibrating the stock gauge. It's in an ideal location, and its **FREE**. On the other hand, the stock gauge tops out at 15 psi, so you might need a different one. The $10 industrial gauge is a lot better deal than any automotive one. Look at www.grainger.com or www.mcmaster.com to find them.
I marked my stock one every 3 psi; the lines will be awfully close together at 1 psi.

11 psi on pump gas is a walk in the park.
As for the boost gauge, they're all a little different, in my 760's (and now my 740) the bottom of the gauge is 13-14 psi, i think its 15 for the 240 turbos.
if you can get the gauge to go to the 3 o'clock position, that should be somewhere around 9-10 psi, just a hair past should be 11.
my roommate has run 15 psi (intercooled) on his with no problems.
but get a real gauge and mount it in an inconspicuous spot, they help much more than black/yellow/red ;)

AM or PM?

I got and industrial gauge, 0 - 30 psi, back mount, +- 1.5% (about $10) mounted it in a switch blank and I rarely ever look at the stock gauge
I run 14 psi on pump gas and use a g-valve for spool-up
