I have a 4in pulley on my Comptech S/C. At 70-85' I log a maximum of 149KPA (7psi). While trying to get my idle correct tonight I went for a few runs at 58'F. Although I did not have traction through first or second, I did log 158KPA. Isn't that almost 1psi more?

 

7kPA = 1psi

 

Shouldn't that be 49 kPa if it is equivalent to 7lbs. 149 kPa would be about 21 psi, far beyond the abilities of the Novi 1000.

 

Sideways- we were trying to figure that out but ya I think it is actually 49kpa. It equates to 4.2v on our MAP sensore. The emanage group told me that 149kpa reading = 7psi

 

Another interesting find: My injector duty cycle is 100% at times with the colder weather. This is with 440's and stock FPR. What is the normal duty cycle with 440's?
