3 bar MAP does it replace MAF on forged inducted car
3 bar MAP does it replace MAF on forged inducted car Im building a ls2 forged with a d-1 procharger... what do i need to do.. what sensors do i need to buy ... someone told me get rid of the MAF all together.. when over 550 hp.... and tune it speed density... os.. idk JUst tell me what i need and ill go buy it lol... I believe i need a 3 bar MAP sensor and and speed density sensor thats aftermarket with a aftermarket harness.. and get rid of my MAF sensor.. which has MAF and speed density in the sae unite.. let me know thanks
It does not replace the MAF per se, it replaces the stock
1-bar MAP sensor which is unable to read boost. The MAP
sensor is the speed density basis (w/ RPM and IAT).
I don't think most belt driven blowers make more than 15PSI
and 15PSI is more than enough for your 550HP (given the
proper supporting mods) so probably a 2-bar would do.
In any case you will also be wanting a custom OS tune
to take advantage of the higher manifold pressure &
sensor.
Take your time and plan it out carefully.

part # for 2-bar sensor is:
12615136
list price is $91.64
but if you know somebody that works at a gm dealership or a garage/shop that has an account with a dealership you can get it for dealer cost which is $57.28
DO NOT goto advance or autozone, they will give you a sensor that is suppose to be a direct interchange for the gm part #. it even looks like the 2-bar, but it will be a 1-bar sensor. I've already been through this, so spend the extra couple of dollars!!!!
