I know this has been answered b4 but cant find it....i tried. Is it true that caold air out performs V2

 

yes it is, but the numbers seem to say otherwise

tov.net has an article on the v2.

 

yes coldair outperforms the V2 on RSX's and EP3 Si's. our two cars the V2 is a short ram. on other platforms, the V2 is a cold air.

 

Actually the V2 is not a short ram. Its considered a hybrid between the two. The V2 IMO out performs an AEM CAI. The numbers seem to agree also.
Honestly, its all a matter of opinion. V2 aren't subject to heat soak like SRI and the possibility of hydrolock is near impossible unless you flood your engine.

Or drive through a lake...

 

silver, it's a short ram. the filter sits in the rear of the engine bay. so it's a short ram. it's better position that other short rams though.


V2 does not outperform a CAI. V2 DOES heatsoak. I've recorded at the track with kpro IAT's of up to 90-140F on the same days my CAI friends recorded IAT of 80F steady.

now when my IAT's were in the 90's, it can be argued that the resonance would make more power up top. but with 140vs80, a 60degree difference, there's no way you can convince me that the resonance is going to do that much.

 

ive read some things from spoon sports, and they say to keep the factory airbox cause you will lose throttle response. Is this true?

 

1. what were the mods that you and the comparable EP were running?
The only way that we can determine it is comparison between dynos.
Even AEM admits to the V2 having higher power increases over its CAI.

I know others who have had SRI, CAI, and a V2 who can vouche for its over all superiority. Temperature isn't everything. Tube lengthing also plays an important role along with resonance.

 

i can vouch for krystar. 2 of my friends running the V2 intake in the ep have been complaining about heat soak. AEM, of course, marketing is marketing. i felt that thing over and over again and it takes quite some time to decrease temperatures. a few other people on this board running the V2 setup have also complained about the heatsoak issues. i believe this has been covered 2 weeks ago, and very so often. let me find that thread.

edit: silver_ep3, are you from walnut creek? we have an ep meet on dec. 11. the ep running on V2 will be there i believe. send PM if interested.

here's that thread:

sry, i don't have an EP3. I have RSX-S and so does my friend that I compared against.

My mods at the time that I did this was V2, Kpro and other stuff (suspension,audio etc) currently i'm on V2 Kpro and race header


I admit resonance does play a part. Hondata has recoginized that V2 will give a nice torq bump at 5800. (well for the typeS) but in the end, you'll still be comparing resonanced 140F air vs unresonanced 80F air. When IAT's are comparable, certainly resonance will be the factor that wins over. But that IAT difference is surely too big for even resonance to make up.

 

you vouch for me? do i know you?

 

i like the way my v2 sounds better then my buddys cold air set up

 

lol. just agreeing with you and vouching for your statements. making sure no one gets mislead.

regards

by the way, this is from ephatch i uncovered. most seem to like theirs on the ep, but check out page 2, middle page. someone copied a piece from AEM's R&D on the V2... heatshield.
