Stock intake mani?

93HatchsBFF · July 16th, 2008, 09:44 PM

so i heard that our stock intake manifolds are good up to like 500Hp and still be Efficient would a after market intake make a difference?

SWEET2KSTANG · July 16th, 2008, 10:32 PM

this has been talked about over and over. the downfall of all aftermarkets are the loss in low end torque. on n/a the stocker is plenty unless you are consistently winding the car past 6k rpm's, if not then an aftermarket intake is not something you need to plan. boosted cars can take advantage of shorter runners and more plentiful plenum area, but again the stocker is still sufficient enough for a street car.

your gonna gain a couple hp and lose some torque and its gonna cost you damn near 800-1000 bux to get it done. not worth it at all. the stocker is a great design

if you want a t-body, accufab i think is the way to go, ive heard nothing but good things from people who have it, 70 or 75mm, i went with 75 because i wasnt sure what i was going to do with my car, might put a s/c on it, i dunno. and for CAI, depends what one you get, i got a steeda, alot of ppl mention JLT, a couple hp up to like 10, maybe more with a tune, it depends

93HatchsBFF · July 17th, 2008, 11:08 PM

cool yeah i was thinking anout doing a 75mm
what up with that duak throttle plates in the throttle bodies i was reading in a magazine this guy had one i was like WTF?
but i got another question. is it true that patriot Heads are just stock heads that have been ported and polished? is thre better heads out there for our cars?

Seabee · July 18th, 2008, 01:12 AM

Currently there are NO aftermarket heads for the 4.6. EVERY head from every company will be ported ford PI heads 152cfm @ .500 lift. A well ported head can flow as good as 173cc intake, and 206cfm at .500 lift depending on the speed shop. The only head I've seen flow better is Fox lake at something like 223.

These are off the top of my head numbers and should be verified before thinking it's gospel.
