i was wondering how i can tell if i have jus a mass air system or the other. ive been told the mass air is the one to have and the other (what ever the other is) is less desirable to have

 

If you have mass air there will be a mass air sensor right after the air filter. What year is yours?

 

its an 87,5.0,ho,lx, notch back. and im pretty sure there is no sensor in the intake tube near the filter. tha being said i must have the pain in the *** system on it i guess. :cry2:

 

Stock vs stock the SD cars are a bit quicker. You can do heads, intake, all the other stuff. Hell i know a few SC & turbo Speed density 5.0s. It can be done. it starts to get tricky when you start playing with the vacume. ie cam swap. There are some nice SD cams out there though.

 

what is sd? sorry but im new, could you tell? :laughhard

 

Speed Density - what you have instead of Mass Air.

 

speed density is arguably the way to go. dollar for dollar spent on mods they are quicker, however there is a limit to them. i haven't come across it and i can run 12s naturally aspitated...with the spray i'm hoping to get close to the 11s

 

well thats good. now i know what the heck i have. thanks guys.

 

With a speed/density system, the ECM (computer) calculates how much fuel and timing advance is needed based on the speed and density of the incoming air.

With a mass air system the ECM (computer) calculates how much fuel and timing advance is needed based on the mass (weight) of the incoming air.

just my 2 cents....

thanks dan but with the speed density system can i adjust the timing manually or should i leave it alone?
