I know that nitrous effectively raises the compression ratio of the engine its used on but is there a formula to figure out what the compression ratio would be changed to per a given shot of spray?

i dont think it raises compresion. you want to lower the compression if your doing a big shot to avoid detonation.2002 NBM Pontiac Firebird Formula<br />Mods: stock...<br />1997 Chevy Camaro *Gone*<br />Mods:Borla,headers,Magnaflow cat, SLP intake, NOS 5175

There's static compression and dynamic compression. It wouldn't change the static compression. Because of the cooling effect on the intake charge (making it more dense), it might be considered to change the dynamic compression. I don't know of a formula for it.
It will definitely increase the cylinder pressure.\'98 A4 Camaro v6->v8 conversion, and STS kit next<br />v6: 13.6 Powerdyne, 13.2 150 shot, 13.8 120 shot, 14.3 85 shot, 15.7 stock<br />v8(na): 12.18@113, 392rwhp<br />Moderator on <a href=\"http://www.mtfba.org\" target=\"_blank\">www.mtfba.org</a> and <a href=\"http://www.frrax.com\" target=\"_blank\">www.frrax.com</a> (Road Race & Autocross)<br /><a href=\"http://community.webshots.com/user/johnduncan10\" target=\"_blank\">Car pics</a>, <a href=\"http://www.trscca.com\" target=\"_blank\">TN Region SCCA</a>

You are thinking of cylinder pressure, not CR.
And yes, nitrous send your cylinder pressure through the freakin' roof.1999 red camaro v6 M5: with a turbo<br />13.52@107.99<br />No, seriously: Who Farted? <br /><a href=\"http://www.cardomain.com/memberpage/600086\" target=\"_blank\">http://www.cardomain.com/memberpage/600086</a>

I've heard.... from nitrous guys at the track.... it makes the car act like a much higher compression car.
I heard rumors.... 20 to 1+
No proof though
Not aware of any formula eitherRace car - gone but not forgotten - 1997 firebird V6
