ive decided ajinst a water/meth system.so how much and what kit to cool the air charge,will 35 work with current tune? if not then ill go 75 or more with custom tune, but im on a stock block,will 75 hang a rod out the side? thanx

 

i wouldnt even think of nitrous without a tune change for it. The rod factor depends on your current mod level

Would have to know the timing, shift points, and A/F of your current program to know if it's safe as is, but as Racer said "you want a n20 program to run n20".

These days with one of the big tuners tuning for you, yes you can keep your rods in running the n20. 50-75 HP would be the highest you'd want to go.
