I'm putting together a forced induction system. I'm trying to calculate how much boost I can run and what compression ratio I need to start out with. I will be making use of an intercooler.
My question is, is there a chart that anyone knows of that shows the compression and heat tolerances of pump gasolines? I need a baseline figure to do some calculations from to see how hard I can push things without having to over-retard my ignition.
Any help would be much appreciated.

What are you doing turbo or supercharger a few people i know have turbocharged a 2.2 4th on standard internals you can run low boost with no problems and very little or no ignition changes i will have to find out what boost they use but any higher and the internals will have to be uprated
Guilty by reason of insanity

Re: Compression Limits of Pump Gasoline
To be safer, get water/methanol injection. You can run the same amount of boost, but more safely since you will have less engine heat and knock/ping.
Turbo is definitely the way to go, the only problem is ensuring it's reliable. Make sure to get tuned, as it's hard to say how much boost is safe for your car since it depends on so many factors... the dyno will tell you.
