25hp for less than $500?

Unless you can actually get that 20-25 at the wheels, it's doubtful anyone will buy a lesser known brand versus C&L/Trickflow/Dragon/Accufab (the established plenums right now)



Those numbers sound incredibly high, if you can do it, you could probably get sales... I dyno'd 255rwhp with 75mm tb, 80mm maf, intake plenum, catted x pipe, pulleys. Take off the x pipe and it's probably a lot less and not near 20-25rwhp...
 


what are you basing these numbers off of, everyone else seems to think they are high?
 
Im pretty sure you dont have to do a dyno, I have never ever heard of anyone getting 25 rwhp from plenum/cai/tb. I would bet you dont pick up more than 10hp from all 3, the plenum tb should be good for about 5hp on a stock engine. The cold air maybe 5hp at the most, I think I might have got 1hp from mine. People are interested in 25hp for under 500 but its got to be legit. Throw in some pullies and it might get you a little closer they are good for about 7hp I think.

I also think they are hight. Besides, if you put in a 100 mm CAI, your MAF/Plenum/TB isn't near that big so it's sorta pointless. You would probably have to get a bigger MAF and have your A/F adjusted on top of that.

Does anyone else agree that's a little too big for a CAI?

EDIT
Just saw you mentioned a MAF in their
