..600 NA horses at 11-1 compresion < the limit for pump gass with a large cam > when fully ported..
well we do know that 11:0.1 is not the absolute higest compression you can run on pump gas. as i've seen a few folks running 14:5.1 compression on the street with 93 octane. using a monster cam to bleed cylinder pressure is the key to that trick. look in last month's (or maybe the one before) hotrod for the primered red nova. another fella i know is running a 401ci LT1 at 12:5.1 on pump gas in the 9's and is a DAILY DRIVEN f-bod. true for most, 11:0.1 is pretty stout on the street but not the absolute limit. just think if we all crusied around living within the limits, we wouldn't have the edge on our competition.

peace,

11-1 is the practicle limit.. the guys who say they are r8uning 14.5 -1 are and may be BUT they never get into it on pump gass 11-1 is the practicle limit for a pump gass car that will actualy be raced with pump gass in it..

 

you could put pump gass in most 14-1 cars and put around in them without detonation yes but put it under load and watch out.

 

EFI changes that rule slightly as the knoc sensor removes timeing dynamicly..
