the lower the boost the less compressor outlet temp and the less pressure drop difference than stock, a bigger FMIC really shines where the stocker falls off(higher boost). of course power delta will decrease as you lower boost but inherently the Helix FMIC should always make more power and take ALOT longer to heatsoak than the stock intercooler,it also removes the less than 2 inch factory charge pipe restriction on both the cold and hot sides. I wouldnt really call 14 psi "hail mary" as this is the 93 octane Attache tune that runs perfectly with no limps,codes or DTC's.

I'd still like to see specs on pressure drop and before and after water temps.
Enough of this,"this is really good" and this gained this much hp. The gains are nice, but I'd like to see these results. It's important that the temps of the engine don't rise any higher than they are already.

I was looking for an IC which performs, is a quality product and most importantly can be installed w/o cutting or any permanent modification to the vehicle so if I ever decide to sell the car I can go back to stock.
However, performance is also an issue as I want to know from which FMIC intake temps are reduced the most and I have the added peace of mind if/when I decide to get a piggyback or reflash. Obviously there will be some sacrifice, the cheapest may not be the most well rounded, nor the most expensive. I am looking for an overall good FMIC to replace the stock unit, I know this may not be beneficial running stock boost, but this is a step I'd like to take towards running more boost safely and cooler. I have an 08 335xi build date (10/07) and I've noticed my temps sometimes go up to 230 when I am pushing the car. Average temps here are in teh low 40s so its pretty cold. |

I am not looking for the one which gives the best #s but requires running bumperless. I am also not looking just to replace my OEM FMIC just to spend money and not provide cooler intake temps or any performance gain. For 1-1200 I imagine there should be some benefit!!! |

It seems if a product like this has been tested thoroughly then these measurements should have been made. Spending less than $100 to add a gauge to determine deltas in water temperature would seem to be an important step. Especially when the product is wider and taller than the original. Please don't get me wrong. Your product looks nice, but i need to be convinced that this won't make my engine run hotter than it already is. I would rather sacrafice warmer air entering my engine with cooler engine temps rather than the opposite.

+1, Don't take this the wrong way, I really like what Helix is doing but I would also need to see some measurement proof that the Helix FMIC won't increase my engine temps before pulling the trigger.

Our datalogger shows coolant temps , I havent seen any changes. The Helix intercoolers dimensions are stock like with the top thinner portion covering approximately 3 inches of the lower part of the radiator. the lower thicker portion DOES NOT, I repeat DOES NOT cover the radiator it fits underneath of it. One other thing of note is our Intercooler uses a pretty free flowing fin density on the ambient side and should not cause much restriction of airflow to the 3 inches of radiator its covering . I know where your concern comes from in other cars that get a large part if the radiator covered with a thick intercooler, this is not the case with our intercooler on the 335i!

Could you post your data logs that you recorded?

If so, please provide what mods are on the car, how long the car has been running, and also the exterior temp at the time.
