Hammer is right the tunning or should i say lack of normally melts one down on the Short of it.
Just Keep in Mind NOS,Blowers ETC....No matter if they have the best tuner in the world dialing it in...Its still gonna wear out an engine Quicker then a normal aspirated engine..Much Quicker !
thats just what a bunch of extra power will do..thats why when i built my new 565 its more of an all muscle car with the ability to take on a smaller shot (200)..No huge gains expected from this...My logic behind this was run 5.60's/70's on motor or build it for all Nos and run high 30's/40's on pulling triggers and a 6 TEEN pig On motor...when i put it like this to myself my decision on which way to go was easy....bottom line your gonna have to give in one area to gain in another its all what you want to do and how fast you want to go....
if i were you i would decide this factor before i went forward with the NOS idea..
