I'm very agree and thanks to shiv for is often very good Update !!!!
Thanks !!!
I have seen that with the vishnu data log the admission temperature is very hot.
Tne stock intercooler is not enough
so I've seen many post on e90post for find the best intercooler, I think the best one quality/price is the Helix motorsport
Core Design-
Prior to this stepped core design you had the option to either go Taller or thicker with the cores. In my design process I measured the captive areas in the front of the bumper in both depth and height and went about designing an intercooler that took up all of this area, yet still retained the all important seal to the back of the fan shroud so the radiator fan could still draw ambient air through the core. The end result is an intercooler with 56% more frontal area as well as core volume. now about the core I was not constrained to an off the shelf core in regards to ambient and internal fin count as we custom spec'd the core to this application the core in the helix FMIC is a single unit stacked up to our specifications in regards to ambient and charge row height and internal and external fin count. since our core has more volume I could increase the internal fin count to remove more temperature and still meet the targeted air flow and pressure drop for this application. as you see by the AIT data logs the intercooler works amazingly well
Endank design- all endtanks are not created equally, air likes to flow in a smooth curved radius as you can see the Helix FMIC has rounded endtanks that are cast. Another thing you will noticie is we opted not to utilize the factory O-ring connectors even though we could have easily implemented them in this design. Our reasoning was simple the factory connectors are THE flow restriction in the charge side as they shrink down to less than 2 inches in diameter at the inlet and outlet.
Install:
Fits in stock location- YES
requires NO cutting,removal and/or permanent modification- Yes on 335i, No on 135i
Can it be installed without removing front Bumper- YES
Utilizes factory mounting points- Yes
Design:
More core volume than stock- Yes 56%
More Ambient face than stock- Yes 56%
More charge rows than stock(
- Yes 13
Bar and Plate construction- Yes
Removes restrictive stock O ring connectors- Yes
Seals to factory radiator fan shroud so air is drawn through when car is not in motion- Yes
Performance:
Helix intercooler at 13.5psi 63 degree ambient temps:
372whp +22whp
turbo outlet temperature 228 degrees F(estimated using a 63 degree ambient and 65% compressor efficiency at 13.5 psi)
AIT temp- 75 degrees F - 54 degree drop over stock
pre and post intercooler temp drop- 153 degrees F
Intercooler efficiency- 93% - 33% improvement in efficiency over stock
Core pressure drop spec is .5psi at 450hp(600cfm) airflow

he said "“I've tested 3 different aftermarket FMICs in my car and the Helix unit performed the best in terms of cooling efficiency and pressure loss. I don't see things getting much better than that to be honest.”

So...... I taked it ....
I've recieved my helix IC in 6 days with fedex :happyanim:
Everythings is perfect :thumsup:
some pictures are better than a big discussion :
thnaks to Alex from Helix motorsport
next on saturday ...
hello everybody.
Helix intercooler was mounting saturday, its very easy and realy "plug and play"
In my car I found it easier to remove the hidden side wheels 8 bolts of 8mm and one off 10mm on each side. we see better to put the silicone sleeves.
I've done it alone with my wife. It takes two people to hold the intercooler in height for the position and put the silicone sleeves at the same time
the pictures ....

BMW is very tiny ...
the final result :love:
