My AEM vs Pop-charger dyno's...
Keep in mind all my dyno numbers are SAE corrected. A few months ago, with just a K&N drop in I dynoed 239hp 240 ft lbs. With this set-up I ran 13.77 @ 101.4 with a 2.052 60ft. 2 weeks ago I went to the same dyno, with an AEM intake, test-pipes, Injen SES and a Crawford plenum. My best run was 243 hp and 245 ft lbs, I was feeling like--->
With this set-up and very bald tires, I ran 13.74 @ 104.1, so I gained 3mph trap and dropped 3 hundredth of a sec, with a crappy 2.16 60ft, obviously making more power, but didnt show up @ the dyno. Anyways, the guys at the shop where I dyno were all talking trash about the plenum, saying the idea is good, but its to pointed where it bends down, leading to turbulance=hp loss, or very little gain, they all told me to junk it. I gave the plenum the benefit of the doubt, and I decided to change out the AEM, I know some people have lost power with theirs. So today I go back to the dyno, same set-up as before just a pop-charger instead of the AEM. My best pull, 254 hp 241 ft lbs. Thats right, on my car I gained 11 whp with a pop-charger over my AEM. I know some of you analysts are going to tell me that different days will yield different results, but I think its fair to say in my case the AEM was hurting me, and the pop-charger isnt
. Now on to the plenum, because I didnt dyno the pleum seperately, I dont know what its doing for me. I can guarantee one thing, I AM NOT making anymore power at redline over my stock plenum. No 18whp @ redline gains for me, same exact power curve as stock, just a little higher. I am installing a crank pulley this week and I'm gonna dyno again in two weeks. After that I will be dynoing my set-up with the stock plenum and see if I gain or lose anything. I will keep everyone posted. BTW, the printer @ the shop wasnt working so I cant post the graphs this weekend. They are going to email me the graphs on Monday. Questions? I'd like to hear them. I'll be heading to the track first week of April with my current set-up plus the pulley and new tires, looking for 13.3-13.4....what do you guys think?

Just to sum it up...
K&N only------> 239hp 240ftlbs 13.77 @ 101.4 w/2.05 60ft
AEM/test-pipes/Injen SES/Crawford Plenum------>243hp 245ftlbs
13.74 @ 104.1 w/2.16 60ft
JWT pop-charger/test-pipes/Injen SES/Crawford plenum--->254 hp 241ftlbs **track times coming in 2 weeks**

.....maybe with 270rwhp and 300lbs of rw-torque........to get any lower than 2.0 60' you gonna need a **** load of torque, and HP gets you higher trap speeds...........GL, the coffee is bruin!

some ppl is claiming that aem CAI lost power cuz hot air in engine bay.
if that is the case, have u warp heat resist wrap on the aluminum tube?
if this is not the case..i should really considering swao my CAI

typically CAI's have longer tubes, which leads to more resisitance, which leads to slower/decreased flow. That is my guess.

I have all my dyno pulls on video, 3 when I was stock, 3 with me AEM set-up and my latest 3 pulls. I will be tranferring them to my computer, early this week. If anybody can host these for me, I'd be glad to post them. The car is so loud with the combination of the test-pipes and the Injen SES, its crazy....hearing my car at redline in 5th sitting next to me is worth the $60 for 3 pulls. Also, I noticed slightly richer air/fuel ratio's with the pop-charger over my AEM.
**One other thing to note. I always get 3 pulls done when I dyno.
With my AEM, every pull I made I would lose power. Wiith the pop-charger every pull I made I gained power. First pull with the pop-charger was 248, 2nd was 250, 3rd was 254.

one thing I did when I had my CAI was I got rid of the aluminum tube and just put back on the OEM plastic tube thus creating less heat, just like the JWT but only cold air...........and I used my heat sheild over the headers.

I actually believe that the filter is what is making all the difference. The stock intake is already cold air, so you are not getting any benefit from that (and maybe loosing HP because most aftermarket CAI's use an aluminum tube instead of the stockers plastic tube). I think the only real drawback to the stock intake is the "small" recatgular filter and its smaller surface area.
Since the pop-charger increases the filter size, I am not surprised that it is working well.
-D'oh!
