nice JDM bling

 

Pro-sec, it would be really be helpful if you could get some dyno pulls before and after you install your ARC intercooler thereby providing some real data that we can compare to other manufacturers. As it stands now we are left with the "faith" that ARC has done sufficient R&D such that their FMIC is better than OEM. I really do not like having to go with "faith" here and ask why doesn't ARC present their comparo data? US based companies do e.g., Buschur has compared the temperature drop in his FMIC relative to OEM. If we do it, then I do not see why the JDM companies cannot also thereby providing some real data that we, the consumer, can make the best decision/purchase.

I'm sure someone will hate on me for this, but for the record I think that many companies JDM and USDM all make some great products. But JDM companies have many people brainwashed or something into thinking that since they have been around longer (meaning tuning their cars) they are inherently better than their American counter parts and therefore can charge considerably more money for something. And since we are brainwashed they don't feel the need to provide data. Don't get me wrong I think this intercooler is more than enough for basically 95% of the people on this board's power goals and is very nice and will perform fantastically, but with the price its incredibly hard for people to justify without it making an extra 20whp or something so that people will think it's worth it. You need concrete quantitative results for people to justify spending lots more on something.

 

THIS!

 

Agreed; so let's see the numbers from ARC assuming they have them so that we may compare to other vendors products. If they will not or have not made comparo, then other means are needed to obtain the information. What is that you ask? Some forum members are purchasing different FMIC for their X's. If they run before and after dynao runs with and w/o the IC and provide these results to EVOm, then we may be able to address whether vendor "A"'s product in, in fact, better than vendor "B"'s product from a performance point of view. Such data acquisition is exactly what is going on, in places, within EVOm it is just that you have to dig for it. More times than not specific conditions (e.g., other aftermarket parts, dyno, atmospheric conditions, etc.) preclude comparison thereby leaving the members in a quandry.
So what to do? Gather as much of the perfromance material as possible on all the vendors and if a vendor (JDM or US) does not provide or have the data then I would not consider purchasing their IC or any other performance part until same became available; go with those that demonstrate real, rather than perceived, benefits.

ARC dyno is here: https://www.evolutionm.net/forums/sh...d.php?t=382035

 

Hey thanks for this information. Looked it over and it appears that:
(1) the air box [=cold air intake?] nets 19 whp (difference between red and black[=OEM] lines)
(2) Air box plus ARC IC yeilded a net increase of 27 whp.
So am I correct in saying the ARC IC alone yeilded a net effect (relative to OEM baseline) of 8 whp?

can't really judge without doing the IC alone. you just can't subtract and say it's only 8 whp. regardless, i don't think it's brainwashing as much as it's just few people here can read japanese, so they don't bother to search japanese sites to find this information.

if you can understand 日本語、then i'm sure you can find what you need about jdm parts. i know i have

 

Would you be so kind, since you have so indicated, to provide what additional whp the ARC IC achieves relative to the OEM unit? Thanks.

This emperical finding from Evogeo today:

I did a before and after on my 4" ets ic and gained 8whp...

^ idk if anyone is interested in that....

If I did it all over again.. I would probly get a 3.5"
Still feel these parts are not additive?

ARC=Quality. Friggin sick.

 

If you ever visit the ARC factory in Japan, you will see that most of their parts are hand welded by little Japanese women.

 

We are not talking about how well crafted they are; rather how well they perform relative to OEM in terms of whp gain; if the best gain also looks good and fits with the least amount of effort to install, so much the better! Trying to recall here but I think Buschur found he got 15 whp over stock IC.
I am really interested in this because all I am looking for is another ~25-27whp and I'm done. Question how to get there with the least amount of stress on the engine with what I currently have.

Was the 15whp gain with or without intercooler pipes? and was it on a bone stock car?

One thing that bothers me is the fitment issue of the BR intercooler.

 

i'll look around. no problem
