I was on the Sr Motorsports page looking at their stuff today and I was on the Intake page. It says one of their intakes will give 11+ HP for the Mazda 3. I have a 2.0 and most Intakes i've looked at say they only give about half that much???

jzoomer

their lying

kargoboy

The honest answer is closer to 3-4 at the wheels on a 2.0, and most of that will be in the upper RPM range.

yeah not that much of a gain. i wish....i know for a fact i didnt any real gain from my cai....maybe up top at high rpm's but not much. talked to a kid i work with...brags about how he mops the floor with all other cars in his stock 07 eclipse gt. said he bought a fujita intake and they had a dyno showing as a gain of 17hp...i was like good luck with that. said they had a dyno so he knows it was correct.

Call him out on it. Make him show you his dyno sheet.

SteveoM3

yeah i thought the same on that... i had heard before that it wasnt that much of a gain but thought i'd see again... hoping to buy from kargoboy when he gets his CAI's in. Just not sure if I should get the Twin Charger CAI or the CarbonFiber one... any suggestions guys??

the fujita intakes shows about 10 hp to the wheels on a 2.3L

jzoomer

yea but if you read the gains on their sheet look at the mods before the intake...usually consist of an exhaust and pully for the base pull and same for when they add the intake....so they have the exhaust already to let the air out so it is going to make a bigger "total" gain if you just add intake you will see 2-5 but if you already have an exhause you will see closer to 10-20 bigger exhaust does no good without bigger intake and vice versa....alone both just make the car sound better but together it actually makes a difference

dentinger

nope.
the guy who i bought the intake off of dyno'd his car stock, then installed the intake, and dyno'd it again...

altho im not sure if he had is vibrant cat back installed before or after the dyno runs....

jzoomer

you will see a bigger gain if you already have an exhaust than if you dont....and same goes for an exhaust you will see a bigger gain if you already have a cai


more air in+ same air out= minor difference
same air in + more air out= minor difference
more air in + more air out= major difference(compairatively)

dentinger

ya, i already know all that...
more in air/more air out = way better flow/way less restrictive
