what kinda specs am i looking at with adding an air foil i heard 40cfm and 6hp but probably not any really dyno reports about it ?

 

i heard they are good if theyre like 20$ or under
otherwise spend the money on something more mod-worthy
just spreading the wealth

 

meaning a little hp as in 5 or less

 

If you still have the stock intake you will not be able to tell the difference after you put it on, at least i didnt...

 

how did your pulleys work for you can feel it good huh did it mess with your volatage im ordering the jet power pulleys so i need to know

 

I noticed a small gain from the pulleys. The engine reved a little faster, but i also did the aluminum drive shaft at the same time. As far as voltage goes, at an idle with my lights on, the gauge reads a little below 13 but once you get going it charges fine. I just have the crank and alt. pulleys, I would imagine you would see a bit more of a gain if you also had the ps pulley. If you do a search on underdrive pulleys, this topic has been discussed about a million times with some good info.
