I'm diggin my AEM V2.....No complaints.....

 

my aem v2 gave a little downlow torque around 3,500 rpms, and a slight hp increase all around which is more noticeable when it's cold out.

the gains are not phenomenal by any means, but the sound is.

 

Well, this is the set-up I used:
First of I installed a T1R test pipe, which by the way only netted me 1HP.Car has only 3,650 miles. Disappointed, I decided to experiment with a filter I have used with extreme succes in the the past on turbo cars: The now discontinued HKS Metal Flow filter (200mmX170MMX80mm opening). This filter incorporates a stainless steel mesh (instead of paper or foam) and a velocity stack (which the Blitz SUS does not use but can be modified to use one from an HKS Super Mega Flow). I proceded to remove the stock filter and install the HKS in the stock box. Results after repeated dyno pulls: 8-9HP (T1R and filter combined). Since the filter is all metal construction (except the velocity stack) I was concerned with heat soak but have not experienced it yet and this includes many miles of city driving in rush hour and I am extremly happy with the improved acceleration.
Filter cost: $103.00. Probably adding a spoon snorkel and hondata gasket will help me net more gains. By the way, left over filters are still available through the internet. Just my 2 cents

 

I'd bet that more than half or your rwhp gain are from the test pipe.

 

The AEM intakes are good and have pretty reproducable results B-U-T you do run the very real risk of hydrolock when using them. IMO, 5rwhp (at best) is not a big enough trade-off for a 10K dollar motor (parts and install).

 

as stated in my response, the T1R testpipe netted .7-1 hp on repeated dyno pulls.combined effect netted 8-9hp.
Peace

 

ummm ok. Well, if that is really the case, then something is REALLY wrong with your test pipe. Seriously, you should be making much more that 1rwhp from a test pipe. Second, do you really believe that you got 7rwhp from a filter?
If so, I think its worth posting the dyno sheets
(1) stock
(2) T1R (stock filter)
(3) HKS filter (without pipe)
(4) HKS and pipe
-something is not right with what you're saying.

BTW, I'm not flamming you, just trying to figure this out b/c it goes against a lot of what I've seen/experienced with test pipes and filters.

 

My friend, I am only relating my personal experience with the testpipe and filter:
Car dynoed stock 197 HP.
two weeks later car dynoed 197.7-198 Hp with the testpipe and 205.5-206.7 by adding the HKS filter. having a mechanical Engineerin background I expected more fron the testpipe and thought the filter was not letting the testpipe reduced backpressure live to its full potential, so I replaced the stock filter with the best flowing one I have come upon, and belive me I have experience with the best flowing filters the market has to offer and this is the best, with the modified Blitz SUS a neck behind. Remenber this is not a kit, just an universal drop in filter.
Yes the 7 additional HP wre fron the combined effect, not the filter alone.
I do realize than I may gain 1-2HP more with the V2 o J's. But costwise, my set-up is probably the best bang fo the buck there is and I don't have to worry about hydrolock.

 

Like I said in my edited post....no flame intended.
How about some pics and specs?
Also, are you changing your oil more frequently? Usually, free flowing= more dirt particles (depending on the filter type...isn't the HKS a Foam filter?)

 

Also, do you have tne dyno sheets? Interesting to see the ambiant temp, correction, and A:F differences between the two dynos.
