boost with speed density
 

I was wondering how many people are running either s/c or turbos with out switching to mass air. I need to know what to upgrade and also if anybody has a good sourse of info on making this work..

Thamks for any info

Send a PM to 88workcar . I'm pretty sure he's running a blower with speed density. He could help you out.

88workcar and yan88GT have ran blowers with speed density.

Thanks guys I'll try to get in touch with them

I installed a A-trim on a 88SD car, you just need a 1 way check vale that goes in the line to the MAP so it will not see the boost, cost $25 from Vortech. Car ran great, but we swapped in a different very healthy motor and went to a MAF set-up.

I have the Vortech check valve if you need it $10 shipped.

88WorkCar yanked his blower off because he couldn't get it to work/perform right.

speed density
 

i have a 86 ( speed density) w/ a a trim car runs fine xept crankcase pressure problems which i fixed

My mechanic switched my car to speed density FAST system. I will let you know as soon as I get it back what it all involves.
