I agree the cooling mods work, no doubt about it, especially if you are running back to back with no time to cool down...and will get there someday, but that isn't what I personally would want to do first...that was the question. I know the 'vert has a 12.1-12.2 in it without the cooling. My launches the night I had the 12.3 wasn't that good, and the place was packed, so I only had 2 passes. The 'vert will get there, but I have the coupe to bring up to power now...so, it is on hold. Again, first dollars I would spend would be on a dual cai of some type, preferably Rob's. My next big expenditure would be whatever pulley set-up you like, and course a tune, if you are done at that point. Tune should come last, after you are done. For example, if you were to chose meth/nitrous, you would want that on before your tune, now, you need gauges to know what is happening to help with the tune...so the $$$$$$ can just add up. You have to plot a course, and stay with it until you reach your peak, or where you want to stop spending...lol...everyone here has their own path...some are still searching, some still finding other ways, tranny mods, rearend mods.....get out your checkbook baby...it can get expensive...lol
