what is the difference between speed density and maf what r the advantages? please advise

 

Speed density is a method of calculating air volume based on pressure and temperature. A MAF sensor calculates air volume based on air temp, barometric pressure and metered airflow either from a hotwire, flapper or karmann vortex generator.

The advantages of using a speed density setup is being able to use a VTA BOV, get rid of the MAF sensor that could be a restriction, be able to drive somewhat normally even with the I/C piping completely blown off. Your only options for converting to speed density include AEM EMS, MAFT Pro or a patched ECU in conjunction with a JDM MAP sensor.

A MAF setup is easier to work with and tune.

 

if you want to have more than 600hp-700hp you have to go speed density. I think the most someone did on maf is 550hp or somewhere around there...

 

is there a cheap way to set up a speed density setup

 

Right at 600whp with a GM MAF and stock ECU.

 

thanks guys
