Thinking about doin a 100 but I read water methonal give you 20% more HP is this True? What you run n20 or water methonal

 

Nitrous will cool the intake charge like a water/meth kit but with the nitrous you get the added HP too.

Water/Meth isn't a traditional power adder...it cools the air charge which in essence allows you run more timing in a boosted application which will net yoy more power.

My vote is to spray it!!!

 

Ok cool I think ill get a 100 to be safe on my stock bottom end

 

100hp shot will be perfectly fine on a stock bottom end.
