turbocharged

This is truly the age of forced induction. A clear indication of the trend came with the release of Honda's 10^th generation Civic. After decades of abstaining from giving the intake manifold any extra assistance, we've been delivered a lifetime of naturally aspirated 4 and 6-cylinder engines, which is not necessarily a bad thing. The turbo-less times lead to some truly remarkable engines from the Japanese giant, but enthusiasts craving the extra boost and whine from a turbo or supercharger were left to their own devices.

While this might not be a 10th Gen, the 8th Gen is a popular platform for aftermarket forced induction kits. Owner Ian Palmeri wanted to ensure that what was going on under the hood matched the outward appearance of his FG2.

Coupled to the K20 is a 1.1l Eaton-style supercharger, bringing this 8th to well over 350 HP and 250 TQ. The 10th Gen's turbo setup might not come with that much power straight off the lot but the L15B7 does have the potential to reach similar numbers

It's autumn and, more importantly, it's the start of prime boosting season.  The cool, dense air that's characteristic of the changing seasons is much easier to compress and cram into the cylinders, while the lower ambient temperatures help the intercooler. Even with the stock set up, your tenth generation Civic has a little extra pep in its step. But there's no reason to settle for just a little pep when you can get more.

Our new intercooler design brought to life, and fresh out of the box from our factory.

When it comes to intercoolers, the old saying "bigger is better" almost always rings true, and even with the spatial restrictions we faced during the design process, we were still able to deliver on that mantra. To start, we added three more rows to our cooler to increase the fin surface area by 97%, almost doubling the amount of area being directly exposed to airflow. This might not come as a surprise to those who saw our design in the last update, but we decided the best direction

It's finally here. After 20 years, and a few extra months of waiting, the Civic Type R has made its way to the States. I have to say, if the standard Civic wasn't striking enough, the Type R has the qualities to make it one scalding hot hatchback. While some of the components carried over from the last generation, including some of the aerodynamics and the return of the mighty K20C1, the FK8 actually went on a bit of a diet and received not only a cosmetic makeover, but also a suspension overhaul fit for the new king of the Nürburgring. It's easy to see why so many are willing to pay thousands over MSRP for the chance to call this new Civic their own.

Something about that wing lets you know that the CTR means business.

There is no denying that the Type R is a performer almost on the same level as premium Porsches or BMWs; and like all performance machines, these cars only perform well if they are maintained. Yes, I'm going to be that guy and talk about maintenance on the hottest hatchback

We've noticed that the 2013+ Ford Focus ST has little wiggle room when it comes to gaining power strictly from bolt-on parts. Even with stage 3 tunes, not many ST's out there see horsepower numbers beyond 300-350hp. That barrier can be surpassed with the use of ethanol or a bigger turbo, but on a stock turbo and pump gas, those numbers aren't going too far north.

With our intercooler, we wanted to bring on some positive effects for the power in this stubborn 2.0L engine. While power is important, we also needed to monitor the outlet temperatures with a visual analysis of heat transfer across the core.

Setting up our prototype for some dyno runs

One of our newer pieces of equipment is a neat little camera that detects thermal activity. It has been pivotal as our visual aid when looking at heat-soak and dispersion across stock intercooler applications, as well as our upgraded prototypes. We used it on our loaner ST to see how the stock unit handled the heat and how we could make it better.

Bigger is better. This is the American ideal that has been the foundation of many in the automotive world. However, in modern times, it's all about consolidation; next-level vehicle technology comes in smaller packages, but broadens the ranges of performance potential. Our engineers shared the modern vision when designing an intercooler for the 2016 Honda Civic 1.5L Turbo. You can't just throw a huge core on this car and call it a day. With a cramped engine bay and the factory intercooler, radiator, and air conditioning condenser tightly bundled together, it's vital we get crafty. It's time to take the road less traveled with the core design to properly surge the maximum amount of cooled air into your Earth Dreams motor.

I mentioned that we are going for height over depth with this design in the last update, making for a unique change compared to other intercoolers. There are two reasons for choosing height. First, if a core

It looks like mother nature is giving the tell-tale signs to us gearheads that it's time to get ready for track season. The weather is getting warmer and tracks all around the country have kicked off calendar seasons with maiden 2017 events already in full swing. A common mod many of us who are boosted, especially ST owners, want during this time of year is the intercooler. The 2013+ Ford Focus ST features quality design for its the factory intercooler, but improved efficiency is something we like to target. In the last update, we talked about the shortcomings of the factory core and how we plan to make an even more efficient intercooler. Now that we have received our production samples for the first time, we can get into the details of the design plan and what our goals are to improve performance.

Intercooler fitment is always a very important aspect of intercooler design. Since the pipes are connected

Mishimoto prides itself on the ability to improve the cooling systems on just about any vehicle that rolls through the garage door. Intercoolers have become our bread and butter at this point. That being said, BMW's are notoriously over-engineered, so improving on the meticulous German design isn't going to be an easy task.

It seems that the engineers at BMW wanted to make sure they provided the best equipment on their "Ultimate Driving Machine," which means tight spacing. Peeling the front bumper cover from our loaner 2014 335i M Sport reveals a space no bigger than a toaster oven. A tricky intercooler project lies ahead, but that's OK, because we're up to the challenge.

The front fascia is secured on tight, but our engineer Steve, left, and project manager, Rob, make short work of it.

BMW already has an adequate design on their stock intercooler. It's a stout tube
