Speed Density CAI

alright.. the IROC im getting tomorrow doesnt run with MAF but instead is speed density. So uh.. I want to do something similar to this: http://www.angelfire.com/ma4/transam/cai.htm but this is for a MAF car.. now.. how would I go on to make one of these for my car? is it the same thing just replace MAF with speed density? I would buy one of those kits from SLP or something but you know how it is when your going to college and you have a crappy as job as a deliver guy :disappoin so I want to make my own. thanks guys.. :eek7:

ahem..

you should be fine, the speed density system wont pickup on the new air box. MAF just took up space in the older cars, thehy went to the density system to eliminate the over use of sensors. good luck
