I'm sorry Dave. I didn't mean to suggest that the intake alone was responsible for the gains. Better driving was probably the largest contributing factor, with conditions being equivalent, but most people don't gain 2mph just by better driving. Some of that is the intake.

And believe me, if/when I change out my intake, I will definitely post the track-verified results.

 

Hmmm, should have put that in the notes... yes, there was fan in front of the car the whole time. To cool it down and to simulate the rushing air.

I did not have all the parts for my stock air box so I could not run a test on that. But I'm now curious if there are gains from the PC, Stillen, AEM, Injen, etc...

 

if anyone don't already know, the fans most dyno shops use are inadequate for providing or simulating the airflow the car sees when at speed...

with the properly sized fan (ideally 30,000 plus cubic feet per minute of airflow), like jet fans used to ventilate tunnels, the hood of the car can be closed and you should still get decent dyno numbers...

 

^ How big of a fan would that be? I recall the one that SP used was at least 4.5' in diameter.

 

Nice,

just wanted to know... where did you buy ur red tubes? or did you paint them urself?

 

I used to think that as well and ran the z-tube/K&N dropin for a long time. But had a chance to try the weapon-R 3.5 inch secret weapon intake. I have driven this car almost every day for over 3 years and I know when something is different. With no dyno #'s, all I can say is that there was a very noticable improvement in torque and overall power. Needless to say, I sold the Z-tube and K/N. YMMV, but on my car, this intake made the car more fun to drive and that is what its all about anyway.

 

Actaully, Pep Boys... Red wire loom 6-7 bucks for a roll of either 1/4", 3/8", and 1/2".

 

I agree.

 

Please do. It's rare someone ever tests a mod like this.

 

Are you meaning track-testing or general testing? I think there is a very decent amount of dyno testing on intake mods IIRC. I am assuming you mean track-tested but I wanted to clarify.

 

Track. There are dynos showing gains from intakes, but a 5whp gain from 6000-6600rpms won't do squat for improving in the 1/4 mile. When you break down the average powerband gain vs acceleration in each gear, the gain is insignificant.

 

Thank you for the clarification. I disagree but regardless it is best that we be clear on these things.

I would think at this point that I am willing to trust the research done by the big names in the industry (Stillen, Crawford, JWT) as to the fact that you are incorrect in at the very least a portion of your statements on this. Feel free to state your reasons I shouldn't if you are so inclined. I would suggest that anyone with question make a real effort to contact the above mentioned folks or do some research on them to get their take on such matters. I have the utmost respect for Doug at Crawford in his knowledge and while I have not met the respective parties for the other companies, I have no reason to feel any differently about them.

As much as I love the track and feel it is a good gauge of some things, I generally feel that a dyno is a far superior for overall information. Again just my opinion.
