But why would you rule out heat soak when that's one of the main downfall's of aftermarket intakes? I also wish dyno's were done with the hood closed to simulate "real world" driving since people don't drive around with their hoods open and have that extra air going to their SRI's.
I opted to do the tests with the hood open because the amount of air the dyno fans were putting out is less than what would be flowing through when the car was on the freeway doing 70... I figured it would be a nice medium to leave the hood open since I was more interested in comparing to highway driving.

Heat soak is really only an issue when you are stopped at a light, once you start moving again the temps stabilize, granted some will drop temps faster than others, like stock compared to a popcharger.

also I fixed the files from 7 to 16, thanks for pointing that out, I knew I would miss something.

Rob - AWESOME job; thoughtful and well-presented. Thanks so much for doing this, I read every word and listened to most of the sound clips, LOL!

Seems you've confirmed what most of us suspected: there just isn't much to be had in terms of gains with just an intake, at least on your setup. It seems reasonable to me, though, that one could infer similar relative results on different (but similar) setups (if that makes sense).

Nice to see that the Stillen did okay though.

I'll leave that decision up to you guys, I'm not here to **** off any manufacturers.

I will however run the stock box with a k&n panel filter until I can get tuned for a 3" MAF intake

very informative. thank you for doing all this as it has been very helpful in making my choice.

On a side note would it be safe to say that adding a K&N drop in with out the Z tube will actually lower my power output or does the Z tube take the blame for that?

GF just bought me a K&N drop in filter for christmas and i dont wanna lower the power on my car lol. i know i wont gain next to nothing with just a panel filter anyway but i figured at least this way i wont have to buy paper filters any more.

any input?

Ok I have a question if I'm understanding this right..the AFR should be in the high 12's?
Now here is my next question when i got my intake and 5/16 spacer I wanted to have my car dynoed to find out how much the HP and TQ the car actually had.. The numbers I got are very different as far at the HP avg goes. I got 196 hp avg, 184 tq avg, and AFR 12.8

After the install of the spacer and intake. I got 202 hp avg, 189 tq avg, and AFR 13.0
So would u say if I changed out the air box to the stock air box i would get more gains since the MAF will sense all the air coming into the intake in one direction?

Wait that doesn't make since once the air passes threw the filter it is traveling in one direction towards the MAF. So the ECU should not be "fooled" which one not cause the car to dump more fuel into the throttle body (carburetor ole skool car guy).

Excellent write up my friend!

I will definitely attest to the exacting measures you took to replicate the conditions for each piece in your testing. I won't say that this is the end all be all for intake testing on the board, but I am positive that with the intakes you tested on YOUR setup, it will be very hard for anyone to come up with a more fair and honest testing procedure. Hats off to you man. Thank you for taking the time to bring this to the community.

Daniel
