im going to run about 8 lbs of boost on a jdm d15 vtec, will i really need to add a 3 bar map sensor?

 

Nope. Not unitl you want over 12psi, and even then guys still use stock ones.

 

yes anything jdm and above you will have to

j/k youll be fine with it stock, especially at 8psi

man jk i sat on this too long trying to work and you beat me to it

 

Yup when you get laid off from work and waiting to start a new Job instead of putting up with the bullshit at the other all I got is free time baby!!!!

 

i heard that the only time u need a 3 bar map is when you pushing close to 30 psi.

 

you heard wrong, at least for a honda

 

naw i push ova 30psi on the stock map sensor and its fine


haha jk

 

Well a Stocker is good til about 12psi. After that the ECU guess' in it's own little way.

Then you can run a 2.5bar, good to 22psi

Then you can run a 3bar, good to 29psi

 

you sir are an idiot. do the math douchebag theres 14.5psi per bar, a 1 bar map sensor (stock on honda's) sounds to me like it would be good to 14.5psi, (even though they arent accurate all the way to 14.5)

what I was woundering is why honda's were made with a map sensor when theoretically they were never meant to have positive pressure in the manifold? feel free to call me a douchebag in return

 

Well you are wrong.

Stock sensor, 1.8bar. Minus Absolute of 14.5psi or 1 bar, you get .8bar in remander.

.8bar=11.6psi
