WHY OEM INTAKES and FILTERS ARE BETTER

SS_Firehawk

Every person except GTLAW (GSXR750 too) must be wrong. Somehow all the empirical evidence we have gathered is wrong too. We are all doomed. The minimum whp expected is 10whp on a modded car, and more as a first mod. The stock intakes are good, but CAI's will create more power, and more than the 4-6 you claim. We should just spam this thread with dyno results.

Bottom line is stock, second line is full exhaust, 3rd line is CAI and pulleys. Looks like my low end has dramatically improved as well. The dyno must be lying.

Hawk -So lets clarify your dyno chart.

Bottom line is bone stock. ?

Middle line is full exhaust. ?

Top line is full exhaust , aftermarket CAI and pulleys ?

If I am correct then where is your dyno chart showing the big HP gains with just a after market CAI , nothing else.

SS_Firehawk

Pay for it and I'll oblige. I can still guarantee gains much higher than 4-6. It's also well known that the more breather mods added, the more diminishing returns. Getting 16whp from an intakes and pulleys is impressive. Subtracting the 5-7 peak whp pulleys actually make is still far and above the stated claim. Let me remind you something I told someone else here. In this world, 1+1 is not 2. AEM, Stillen Akuma, and AAM have seen gains of 15-18whp on a stock vehicle. I suppose they are lying too. I'll be more than happy to pull their dynos for you.

So you refuse to answer a simple question useless someone pays you ! (WTF)

You can't explain your own dyno posting, makes no sense !!!

Also look at the most of the dyno charts you provide, pretty much the same baseline HP and Torque curve for most of the charts until 6500 RPM. Like I said how often are you are going be driving between 6500 and 7500 RPM.

The other charts you provide only show a better torque and hp curve when the exhaust is also changed.

GTLAW

Again, if the car could be tested having Air RAM into the stock intakes! it would give you the HP your looking for! reason aftermarket intakes give that HP boast on a dyno is because you are running the car at max speeds with open filters! it's not real world driving

you do realize when on a dyno they have large fans blowing air into the front of the car for intake/cooling purposes. it may not be 100% accurate for actual speeds you hit at the high end on a dyno but still there's air.

even "real world" driving i'll take my aftermarket intakes over those giant ugly inefficient air boxes any day.
