hey guys i have a h22a4 im boosting 7psi i want to know what shot of nitrous i can use for cooling the intercooler and where do i drill for the nozzle

 

if you want to cool the intercooler you need an intercooler spraybar. it doesnt require jets it just sprays full force. you can also use co2( I think) with this setup(correct me if im wrong) because its cheaper than nitrous but has the same cooling effect. with the spraybar the nitrous doesnt enter the engine it just sprays through the intercooler fins. you can also modify your windshield squirter setup to spray ice water through the intercooler for a similar effect.
