RPI FMIC IAT's are 20-25°F lower than OEM FMIC IAT's.
Both logs are 2-3-4 gear logs

OEM FMIC IAT at 205km/h (127mph): 113°F
RPI FMIC IAT at 205km/h (127mph): 90°F

Are your pistons upgraded or just lower compression? what ratio? 8.8?

I have some amazing logs of xo2 fmic. The spearco knock off, godspeed, etc... It was altered to sit higher, closer to the radiator so the flow may have changed a bit but my logs at 14 psi look amazing. Temps are super low and there his less than 1 psi pressure drop. A log after at 18 psi (target) show boost at only 15 psi. Almost a 3 psi drop in pressure until I get to 5th gear.

Pressure drop was due to a v band clamp that was left loose during warranty work at the dealership.

Looks like the XO2 will perform as well or better than the much smaller ETS.

Hi,

All the Alpina's are equipped with high-strength Mahle piston with a compression of 9,4: 1.

i asked to them that they complete the board with all US IC (Helix etc)

I received the answer from Wagner Tuning very quickly.

here is the answer. You could contact me for international sales also

Yea this was a great thread, should be stickied when more people post some independent datalogs.

[**335i**]

soon hope to post big toms ic logs

[klipseracer]

I don't have an N54 anymore (thinking about getting another) but if someone puts together a post, I will update the first post with better information. Any vendors can feel free to ask me to delete and update with newer information as well as long as its formatted, I will copy and paste it.

Can any1 indicate the weight of the Helix intercooler....cant find it anywhere

The Helix FMIC weighs 27lbs, any physics geeks out there that can compute how much heat 27 lbs of aluminum can absorb before it heatsoaks??? The # is staggering and is one of the reasons why our fmic works so well!

[Proper Motion LLC]

Why are we assuming all these aftermarket FMIC's have .5 pressure drop.

If a FMIC has a pressure drop of like 2.0, and your doing your calculations based on .5 pressure drop, than that's a huge fake advantage for that high pressure drop FMIC.

I don't believe any pressure drop numbers until we actually flow bench test multiple FMIC's at once

[JRubin13]

Im sorry, but going way way back to the first post with Shivs comments, in the end are the FMIC's useful or not? Very curious as im currently debating weather buying one or not.

[m3dragon]

So took me a while to read all the pages..

So based on the thread the conclusion was Hilex was the best for dropping temps as well as had the least pressure drop?

I am not going for crazy mods but I know the stock FMIC in CA will get toasty fast. So I want to replace it for a DD setup. With that having the least pressure drop would be the best correct?

Thanks

In my opinion if one were truly better then the other instead of just talking they would buy the competitor IC and do the testing instead of what you have in here(lots of claims boasting). Buy one that suits your needs for example no cutting or factory connections. To many things that can alter the data. No real conclusion is what I got from it.

So if I used a dart board like the weather man I would get my best answer.. Well that just sucks.

[ale5six1]

well i just ordered the evolution racewerks FMIC w/ carbon shroud. should be here in 4-6 weeks due to the delay in shrouds. I plan on putting it on my car right after it arrives. but what kind of equipment due I need to test these temperatures? I also might dyno the car after, just to see how much power i picked up.

[cityazndan]

^ Ditto. I just ordered my ER FMIC black with CF shroud...curious as to the IATs.

[MCweapon]

Based on what I have seen here and other threads, I'm going with the Helix.

[Jeffman]

Helix for me too! And hopefully I'll have the guys in Manayunk handle the install too. Somebody please PM me with experimental data showing that an oil catch can is necessary with boosting up to 18 psi. Thanks.

[barton2002]

Guys,

this thread is great but can someone jus clarify few things for me, can we conclude that Helix can b the best FMIC. How about ETS? It has the most pressure drop but from the data posted by Michael @ ETS (If i rmber his name right) that it has the best ability to keep IAT low? I just bought one and it is sitting in the garage waiting to be installed... would definitely like to know what is the downside of higher pressure drop.. Can I not run a more aggressive map to "artifically keep the boost level high, so that it will be back to the PSI level I wanted despite the effect of pressure drop? Sorry about this noob question but Im a bit lost after reading so many people's different view and comments.

Thanks,
B
