I will ask again because I think this IS a key question. How fast are you trying to go?
Looking at the times in your sig I can tell you that I have gone 1/2 a second faster @ 4-5 mph more, with a 60ft time .3 - .4 slower than yours (2.2 or 2.3). This was with no alky, no propane, no intercooler. It was also with a wiped cam and a below stock CR of somewhere in the 7:1 range from head gaskets that were more than 3X stock thickness (hey, I didnt know ). Car was the biggest 6cyl pig out there, running rich was an understatement (almost same gas mileage as my Suburban). I would race with my FP set at 32psi . It didnt matter whether it was at 32 or 42, no difference in performance. Boost anywhere from 15-26, no diff in performance. Yes, I even ran with only 32-34psi FP w/ 25~ #s of boost, thats how out of whack it was that it wouldnt blow up! Too much space in chambers + valves not opening up like they should = a lot of air probably sitting around/not pushing through like it should. Oh yeah, too thick head gaskets also caused a inadequate lifter preload issue (probably 0 preload!) that I believe hurts topend. So I was basically f***ed. As if that wasnt enough I had a false KR issue form a faulty ESC. A 20* chip with 17~* of false KR does not help running down the track. If I think hard enough I could probably mention something else like header leaks (which dont help these cars at all), but I think the above mentioned is enough.
Okay, besides making myself feel good thinking of all the lost performance I should gain from correcting the problems (not to mention the head porting I just did) this should be enough to show the potential that is there, before adding an intercooler, or finally being able to effectively utilize the alky/H2O. Granted you dont have the problems I did there is no reason you shouldnt be able to run faster by focusing on improving whats there and through the #1 "mod": TUNING.
Did I mention that I have never ran on slicks either? Nor race gas? I believe that I can get this car to very low 13s/probably break into the 12s through TUNING. If I add slicks/race gas theres no question, but Im going to tune as far as I can in street trim first. Adding slicks, race gas, an intercooler, is only icing on the cake to get to that next plateau(s) of performance when the time comes.
How fast do you want to go? 13s beats 90% of whats on the street.
