Question Porting A Stock Intake Manifold?

what kind of horsepower geins can i expect to get from porting the stock manifold? i have a nice polished manifold and would really like to keep it since it looks good on the car.

the lower intake is pretty small, and from what ive read its not worth doing that to a stock intake manifold..if you have a little extra cash, you can pick up a cobra intake for about $200 and thatd be worth it

id have to agree. spend a couple of bucks and grab a cobra or explorer intake, and then spend some time a polish that one up. still wont see a whole lot of power gains tho.

well with that cobra you will mostly see a gain in torque and probably about 10-20hp gain in low to mid range rpm

Depends on who's porting it. The lower intake is very restrictive (especially the front no.1 and no. 5 runners) so it doesn't take much work to improve it substantially. Contact tmoss. He's the intake porting expert and is very capable of extracting a lot of HP/TQ out of stock parts.

isnt tmoss really expensive?
and if your going to port your stock intake, might as well let him do the e7 heads too

Not worth the time or money to port a stock intake unless youir doing it your self.....If you plan on having some one else do it then IMO its a waste of money

Probably true and that also applies to the stock E7 heads. I ported my own stock intake/heads and with all the other bolt-ons, my Stang put down 229rwhp/277rwtq which was 61rwhp/59rwtq more than stock. Pretty good, I thought, until I did the Edelbrock Performer intake swap ($182 from ebay). That added a further 15rwhp/7rwtq and 1mpg so really, you might as well swap in a better intake from the outset.

if your not lookin to spend more then 200-250 bucks, take a look on craigslist for a nice used one. edelbrock performer is good, (i personally dont like the RPM intake) or trick flow is very popular.
