can u have a mechanical nitrous pressure guage in your car and have it be legal for racing?

 

sure can. mech. n2o guages have a restrictor fitting and are allowed to be plumbed in the car.

 

i heard its a PITA install though if out inside the car no?

 

ok i got a autometer np guage what else do i need to buy. the braided line that i got screws right on to the back, so do i just get a longer line and run it in to the car? and having this in the car in nhra legal?

 

Yes it's legal,and yes you need a longer braided line. Biggest pita is getting the braided line snaked to where it has to go.

 

ok i got a guage pod that i am going to put it in. where do i run the line in? what's the easiest way?

 

I ran mine to a purge adapter at the solonoid pita to make a hole in the fire wall
