kind of a shame it has to be that way.
I agree and that is a shame. I hope we make it through this new set of new rules but if not I will get more done in the shop. Time will tell but it don't look good.

my plan was already set to run C-23 so i think i'll stick with that. as far as reading plugs, i've never had a problem with that regardless of the fuel i used.
the cars pretty heavy at 3400 lbs so hopefully i can sneak a 7.8 or better out of it. it's just gonna depend on how many passes i can get in to nail down the tune.
if anyone even remotely cares what it runs i'll post the results, if not, no big deal either way.

Why a post about nitrous was moved to the general section shows the ignorance of someone who did not read the post. It's Nitrous Oxide not New Old Stock (NOS).  rant over To give my opinion on the question asked, with your compression ratio and spraying 600HP I woulds say C23 or NO2 at a minimum.  Mike Gray
