I have yet to test the ATM/Helix in this situation.įor guys looking for their first FMIC, ATM/Helix gets the nod from me. Lots of back to back roll races in Mexico and the ETS can show some heat retention quicker than I'd like. I didn't log my first two pulls with the ATM/Helix so this was a third pull with little cool down. I have noticed that the ATM seems to recover quicker and seems to hold closer to ambient for longer.

The ATM/Helix still has the edge though the ETS 5" is a solid performer. So overall the results were pretty close. Checking the IAT at the same ending RPM as the ETS and it was 110F at the same point for a 23F increase.

The end of the pull was 113F for 26F increase. The pulls both started within 50 RPM over each other as noted by throttle position/RPM. As the logs go on the temps do climb and don't recover as fast.ĪTM started at 87F or 7 degrees over ambient. The end of the pull was 124F for a 31F increase. In day to day driving I saw (8-15F over ambient when cruising). They did nicely.ĮTS started about 93F or 15F over ambient. BMS Power Package 6: BMS N54 JB4 + Evolution Racewerks FMIC. BMS Power Package 3: BMS JB4 N54 and VRSF Downpipes N54. I did this to see how quickly temps would recover. BMS Power Package 2: BMS JB4 N54 + ETS 5' Intercooler. ATM pull was 3rd of the night with with no cool down other than turning around at the end of the road and driving about 1/2 mile. For the ATM pull it was 80F with about 80% humidity.

For the ETS pull it was 78 degrees with about 80% humidity. I did a 3rd-5th log on back to back nights. Not sure if any other others have experienced that. I used an extra piece of silicone and wedged it in between the heat exchanger and the elbow. The J pipe design did place the silicone elbow going to the FMIC closer to the oil heat exchanger than I'd like. Fit was excellent with no cutting required. Fit and finish was definitely impressive with excellent welds and a high quality core. But how about a test vs two quality FMICs?ĪTM has continued to improve on the initial Helix design. The results of those are going to be obvious. We see a lot of comparisons with aftermarket FMICs to stock. The ETS has done well even in these 100+F Carolina summer days with no meth but I couldn't pass up the chance to get the FMIC I really wanted. Helix was considered the best for IAT suppression and was the first with the stepped design for our cars. I even hunted for a few months for a used one with no luck. I have always been a big fan of the Helix FMIC and when I went to purchase my first FMIC I was disappointed because at that time they had stopped making them. I have seen it on par with and even out perform friends cars with competitor 6" and 7" units running less aggressive tunes than I. I've been running an ETS 5" FMIC for awhile and have always been impressed with its performance. Circled in red for reference since I didn't include boost in the attached logs.Hey guys. I couldn't be happier with the performance of this FMIC and the customer support of the whole team down at VRSF! A+ well done!!! The results were staggering! Keep in mind the before log was taken in March where ambient air temperature was a lot cooler here in Virginia than it was when I took the after log in May with the 7.5". I've posted some before and after logs from the old school VRSF 7" FMIC in comparison to the new VRSF 7.5" Stepped Race FMIC. The purpose of that plastic is to channel air down to the stock FMIC.

Yes, you have to trim A LOT of the plastic that sits behind your bumper cover but don't worry, none of it is structural at all. The installation was very straight forward and only took me about two hours from start to completion. I made an unboxing video and posted it to my YouTube, link is posted below if you are interested in watching it so you will have an expectation on what you will receive. Anyways lets get back on track, I ordered the 7.5" FMIC from VRSF on Sunday May 5th 2019 and received it Wednesday, May 8th 2019. I made 613 WHP on 26 psi at -9.8 degrees timing. I was victim to massive amounts of heat soak leading to massive amounts of timing being pulled out of the engine. Lets start off with my over all experience with VRSF, I placed the order for this on Sunday May 5th, 2019 after a very disappointing pull on the dyno for Boost Crews Mayhem Meet. I wont tell you anything you cant already find on their website under the product description for there is no need to be redundant. I'm here to give you guys a detailed review of the VRSF 7.5" Race FMIC.
