Intake + Exhaust = what hp gains overall?

K&N drop-in intakes?!?!?!? plus an exhaust is 300whp? Holy moly. No other mods? Isn't that kindda high. I wonder what gains I have right now by just adding an exhaust, with no other mods. Did I gain like 15whp? (no access to a dyno in my small timbuktu town

)

As far as K&N drop-ins... aside from the worry about fouling the MAF sensor (I am still on the fence regarding this... seen both sides of story), what I am worried about are more the particulates that get in. I mean this from the standpoint that I noticed on my G35, that since I switched to K&N, my oil was a lot darker than pre-K&N. Not sure if there's any truth to that at all... but I also read around that some folks did notice that too. Now what that means.... I would be led to believe that the engine is simply running dirtier... maybe someone else can enlighten me on that topic.

Yes, I am thinking about getting HFC's instead of getting a CAI. So if I have a CBE and HFC's, is a tune needed? I would like to NOT get a tune... don't want to void the warranty just yet. Maybe in a couple of years

He was spamming other threads with complete gibberish, I don't see how does "o2 airflow can cesspool" sounds normal or makes sense as can be said about the rest of the post. FYI, a cesspool is a large pit to dispose sewage or refuse.

The oil color after several cycles can very depending on the type of oil you use. The darkening happens when the oil absorbs carbon deposits from detonation. I could be wrong, but I'm assuming low grade gasoline would have this effect. The K&N filters out the same amount of particles as paper filters if oiled correctly. The oil is there to compensate for the larger openings. I have about 6k miles with my K&N's without any problems. I honestly don't know of anyone having the MAF sensor issue aside from unreliable sources.K&N Mass Air Flow Sensor Statement

Just gibberish?

wdkwang · 04-19-2011, 11:45 AM

i personally dont think 300whp is high but i have the k&n short ram intakes and borla exhaust. it did get a ecu tune.
our z's make 276whp stock, so my numbers are relatively average

I need help! Can somebody tell me if i will lose or gain power if i put intakes with stock exhaust?

Gain.

primariy differences with HFC's are cell count (200 or 300 [lower cell = freer flowing]), if they are metallic or ceramic, and whether they are resonated or not.

I just dyno'd 321/268

Test pipes
Stillen exhaust

NO TUNE!!!

Would love to hear a sound bite of this set up. Im thinking about test pipes, but im worried it would be too loud ( I already have the G3 and Stillen CBE).

What type of dyno?
