Can you tell a difference with just an aftermarket plenum?

You'll definitely feel the plenum and TB combo.

My favorite was a girl customer we had that when we were done installing it, she backed out and laid a patch of rubber in reverse. she says "Wow, I was just backing up!"

Not that the 10+hp is that intense or anything, it just made us all laugh at her...regardless you'll feel it.
 
If you have a dremel tool, try polishing the TB and plenum first. I don't think you'll be disappointed with this "free" mod.

Then, if you want a larger intake flow, go for the aftermarket one. You won't be out anything and you can sell your stocker for more to someone on eBay. I've seen people do this and I think it's funny.

Thanks for the help and Today, jstreet0204 thanks for the sites, big help with my decision. I think ill go with the accufab. It seems like a cheap way to get extra ponies out of my pony.


I wish they would have polished the stock'er and used that as another option in their testing. I think it would have kept with the competition, but not the Accufab...
 
accufab does make the most, but i dont see it worth the extra 100+ for 1 more horse. i prefer the middle ground, and went with the dragon +75mm TB. I will also be polishing the dragon plenum to get more power from hthe semi rough casting.
