Keeping cool is the key to a reliable track car. To add more coolness, I attacked the problem using two methods: adding better heat exchangers and adding airflow. I’ve shown you what the new fluid temperatures have been after the modifications, but what about the actual air temperatures? I added some thermocouples to find out.

The guys at Motovicity have been singing the praises of HKS's new Max IV coilover systems to us for a while. While we have generally always been impressed with HKS's tidy OEM like engineering, it was a while since we had experienced their coilovers. In the early 2000's we had tried some of the original Hipermax suspensions on a few of our cars and although we found them to be of high quality and smooth riding, they did not have enough spring rate and damping for serious performance with big sticky tires and especially track use. We sort of regulated the brand as nice for street use only and looked toward other places for suspension for our projects.
Fast forward 10 years and 4 generations of Hipermax suspension later, plus Motovicity's raving about them made us eager to get our hands on the Hipermax or Max 4 suspension system for another review.

The whole point of modifying cars with go-fast parts is to go fast right? So of course, Project S2000 required a good romping at Buttonwillow after the installation of the Blacktrax Performance/Kingpin Machine spherical bearing suspension setup and Hasport rear differential mounts. The car is also in a constant state of tweaking requiring adjustments along the way as lessons are learned. Everything is better with video too and Replay XD stepped in to help.

I’m often of the philosophy of replacing things as they wear out. And when they wear out, I might as well upgrade! It all started with a slight banging noise while going over bumps. Over a bit of time, it got progressively worse. Eventually, going over any type of bump including creeping over speed bumps caused a loud banging noise. What was the source?

Everyone who has experienced trying to design parts to get more power of the S2000 naturally aspirated can attest to Honda not having left much on the table. Honda was of course limited by pesky general consumer things related to NVH. If you throw those concerns off the table, is there anything to be gained?

Did I mention there would be more hood hacking? Why yes I did. Somewhere along the other 18 parts of this project, I noticed the stock air box looked relatively well sealed along with having a location ideal for ram air. Ram air is used on practically every sport bike you can buy to coax as much power as possible from the engine. Even cars such as the Corvette Z06 and Dodge Viper use ram air.

The destroyer of all track vehicles is excessive heat. Whether it is the coolant, various oils, or brakes, too much heat will lead to failures. On Project S2000, we’ve already addressed the engine coolant and oil temperatures with an upgraded Koyo radiator and Earls Temp-A-Cure oil cooler. These heat exchangers depend on airflow to in order to remove heat from the coolant and oil. No airflow means no cooling, hence the need for fans when the car is sitting still. One way to improve the airflow through the heat exchangers is to minimize the resistance to the air exiting from behind the heat exchangers. For the vast majority of street cars, all the air has to dump out the bottom of the engine bay. So how do we minimize the resistance to airflow? By increasing the area the air has available to exit. In this case, we’re venting the hood.

Project S2000: Testing Temps and Tools (Replay Camera and IR Pyrometer)
by Khiem Dinh
At my last track day, I got an IR pyrometer as a new toy for taking some data. For this track day, I added a Replay XD1080 HD video camera to the mix to replace my previous camera (which met an untimely demise). Furthermore, a few friends of MotoIQ were also in attendance to join in on some track day fun. Video was taken and many temperatures were measured. Keep on reading to see how the Replay works and different brake systems stacked up.

Project S2000 - Testing Track Upgrades and Custom Brake Ducts
By Khiem Dinh
All of the stars aligned a few weeks ago and I took Project S2000 to the track. Centerforce clutch and AP1 flywheel – installed and broken-in, Hasport engine mounts – installed and broken-in, custom brake ducts – prototyped and test-fitted, K.R.O.P.S holding track day at Willow Springs – scheduled, other MotoIQ project cars going – check. Custom brake ducts? Let's start with those.

Project S2000 - Making a More Responsive Drivetrain
By Khiem Dinh
The AP2 generation of S2000s were made a bit cushier and street friendly compared to the AP1s for the general American consumer. A larger displacement engine along with shorter gearing were specified to give more torque at the wheels which Americans desired. However, Honda also matched a heavier flywheel and modified the clutch system with both negatively impacting the level of track aptitude. Step 2 of Phase 2 is to shift the drivetrain bias more towards the track side of the equation compromising some everyday livability for better performance.
