Negative CAI effects

real fake yea....some DYNO GRAPHS HAVE SHOWN that people have put down 260whp compare to 230-240 stock of what they got, thats y i ranged it from 20-40

I know what you say is true. I have also read that same information and your not far off with those numbers.(drive2)

i think desperado's point is that dyno numbers are pretty easy to fudge...especially for a turbocharged engine. if you were to do 10 separate dyno runs of the same car, you would likely get 10 different graphs of the results with a rather noticeable variance from the "best" run and the "worst" run. now, if you were to just extrapolate this and take the "best" run from the post-CAI and "worst" run from the pre-CAI graphs, then it would be very easy to show a huge difference in performance. not only this, but different types of dynos give different numbers. the dynojet gives numbers significantly higher than the mustang dyno. in addition to this, differing ventilation conditions from run to run can noticeably impact the results. the differences may not be big, but they're the ones who should theoretically show up on a dyno graph and impact the shape of the torque/hp curve.

in the end, when you consider all these factors, what do you REALLY know when someone shows you a dyno graph of their supposed gains? not to be negative, but i, personally, don't really know what to think when i see someone's dyno graph anymore...;o
 
Its really getting to the point though were none of these numbers matter. There are so many little tricks to get a dyno to read a certain way, so many ways to fudge up the numbers. I really don't buy dynos, track slips, any of that any more. Crunching the numbers may be fun, but really, the only way to tell for sure is to go out, line 'em up, and find out who is faster by whose in front when the race ends.

I personally prefere a CAI. I think it cleans up the engine bay a bit, looks good, and sounds nice. I have the CP-e intake, and the way its mounted, it would take more than just a bit of rain to get hydrolock. From a visual guestimate standing outside the car, but looking at where it is installed, I would have to say you would be a fool to drive in the type of flood water that would get you some hydrolock. It would have to be about a quarter or more of the way up the wheel. My friend brought up the slits in the wheel well...there is no way a substantial amount of water to hydrolock would just randomly splash in there.

Go with whatever one looks best to you, you can afford, etc. Its all really just personal preference at the end of the day.

Well, by Clos' own numbers he's off by at least 10 hp. My point is just don't expect to get more than around 20-25 corrected Dynojet hp from the intake alone. Add EMS, or an exhaust mod that gets rid of or reduces restrictions pre-muffler, and you can get that kind that kind of an increase. But not from the intake alone.

Actually, I'm just mad b/c I got a crappy dyno from a place that didn't know how to dyno FWD and I ended up with only 239 hp with my CP-E, up 15 from stock. Once I re-dyno somewhere else and get my own 250-260 hp or more dyno, I'll stop jumping on other people's dynos.

Dont get me wrong I believe with a good CAI will result in better overall performance. Right now its winter time bascially and all cars will be hard pressed to see which is better wit ha SRI or CAI but come summer time heat is the beast. A SRI will be getting all that engine heat plus 90+ degree weather depending where you live I personally plan to go with the MS CAI.
 
i dont kno what yall are still debating about, i have had both on my car and felt no diff. between the two
 
This "debate" is all really on preference. There is un-denyable proof of the gains a CAI OR SRI will deliver. The gains at flywheel or wheel horsepower depend greatly on the car itself, and although I guess a dynometer can be tampered, it still serves its purpose. Generally, where the car lacks the most in power is where you want to increase. Generally in the feild of cars, whats more expensive is usally better quality, although gems do come along now and again. Never ever think that speed is cheap. Its not.

And as far as which to pick, I could only tell you that firsthand knowledge tells me most people opt for a CAI, and see larger power gains from it. But remember, whp is whats most important, and most cars would be very lucky to see 15whp gain.
 
Not true,depends what intake,if they went and put in a short ram then yeah,its hardly suprising.The best intakes are AEM and INJEN ,my oppinion the MS3 adds a bit of cosmetic appeal too.You must also buy the hydro guard to go with it.It lets in air and not water also protects it from sand,dust,sludge,smaller particles that screw up your engine.

Does the hydro guard protect against hydrolock?
