A F R question?
A F R question? Everyone(companies) are working the afr's to make them better results.Im gonna get some of afr's heads.I want the best or something very close.from your experience or research who's the man on modding afr's.My car has a G5X2 cam,dynotech 1 3/4-1 7/8 lt,true duals,x pipe in future,bbk 80mm tb,ls6 intake and other stuff that dont matter right now.while reading through some threads Ive seen people using 225 w/ smaller chambers does this sound right.Is that something that I could use for now until I decide to get more cubics than stock displacement? Which kind of afr's would do me the best hp/tq 205 or 225 ?And what the hell are you paying for all of this ?400 rwhp isnt enough I need more. Thanks for your help!

From what ive seen you will make more power with 205s on stock cubes. They like a "smallish" cam to perform best...
Just get the 225s though...they will be what you need with a stroker...whats a couple hp now?...

Im in the same dilemma I will probably get a 402 or 427 next year but for now have stock cubes. Im going with the 205s with the G5x3 and upgrade later if needed. I figured will I really need more than 500 rwhp and nitous on top of it? I think I would be smarter worrying about keeping the power to the ground. Besides you can get into the mid 10s with the combo Im talking about with a little spray. Any faster and Im not really driving a fun street car anymore!
