[Buick] Boosting up - 2 or 3 Bar MAP sensor

[JA2Z]

Hi Guys,

I'm currently running a Blower with a pulley that only gives me about 2.5psi (which actually gives me only 1.5 psi Positive Boost because without the blower the Boost/Vac reading at full throttle under full load is 2 inches Hg below 0 and with the blower on, it pushes the reading up to 1.5 psi

long story short.... I want More

so... I've Got Super6 Injectors and am making a pulley to suit somewhere between 8-12 psi positive Boost.

Question is:

Can i use a 3 Bar MAP sensor, or should i really be running a 2 Bar MAP sensor?

A 2 BAR MAP will do the trick. If you use a 3 BAR it will give poorer resoloution in the tune due to the larger scaling needed.

2bar is good for 14.5psi
3bar is good for 29psi

the 2bar$5d doesn't have great resolution. but works fine

a 2 or 3 Bar kalamker tune would have really good resolution

i'm going to assume you have a SC14. in which case the 2bar will be more then the charger will ever put out

Thanks guys.

Do any of you suggest a good place to buy 2 Bar MAP sensors?
