Remember our final round of Time Attack<\/strong> at Brands Hatch<\/strong> all the way back in September last year? That’s where we first mentioned some big changes to our NSX<\/strong> through the winter. Well, winter is upon us and the 2021 build is well underway and we\u2019re sure you guys are keen to see what it entails and how it\u2019s developing!<\/p>\n

Tyre Upgrade<\/strong><\/h4>\n

After winning the Club 2WD<\/strong> title last year, it\u2019s only right that we take the next step up into the \u2018big boy\u2019 leagues of the Pro Extreme<\/strong> and Pro<\/strong> classes that Time Attack<\/strong> has to offer. Although we\u2019re still undecided on which of the 2 classes we\u2019ll find ourselves in, a tyre upgrade is necessary to be eligible for the step up in class. So, we\u2019ve now moved away from the MSA list 1A and 1B tyres and made the move to a Pirelli<\/strong> racing slick. It goes without saying that we\u2019ll see a huge increase in grip levels and an almighty drop in lap times too. Here\u2019s a shot of our test fit to the front right corner, with the Pirelli\/WedsSport<\/a><\/strong> combination filling the wide arches rather nicely.<\/p>\n

\"\"<\/a><\/p>\n

Aero<\/strong>\u00a0<\/strong><\/h4>\n

Time Attack<\/strong> cars are renowned for their monstrous wings and over the top body kits, but it\u2019s all in the name of aerodynamics. These wings and spoilers that we often see help the car to carve through the air and push it down onto the track to create downforce. The more downforce you generate, the more speed you can carry through corners, the quicker your lap times are. Simple.<\/p>\n

Our NSX<\/strong> is no exception either. We upgraded to larger front wings halfway through the 2020 season to accommodate a larger front wheel to improve front end grip. We\u2019ve now paired these up with a brand-new aero bumper that will allow more air flow and a larger splitter too. As you can see its still in the process of being developed by our in-house technician, Fordy.<\/p>\n

\"\"<\/a><\/p>\n

We\u2019ve also enlisted the help of motorsport fabricator and engineer, Andy, from ICEFAB<\/strong><\/a>. He\u2019s been tasked with cooking up a bespoke diffuser to help the rear of the car stay more planted. He\u2019s got a couple of other tasks too, but we\u2019ll chat about that a bit later on!<\/p>\n

Engine<\/strong><\/h4>\n

With the bumper and slicks test fitted, it was time to take the car down the road to the guys at Motion Motorsport<\/strong><\/a>. As you know, Motion<\/strong> help run our cars at race weekends and are responsible for carrying out all the mechanical work that the car needs.<\/p>\n

\"\"<\/a><\/p>\n

No sooner had the NSX<\/strong> arrived, than it was on a ramp and the Skunk2<\/strong><\/a> built K24 power plant safely taken out. Now, if we\u2019re planning on challenging for victories in Time Attack<\/strong>, you might be wondering how we\u2019re going to do that with our current naturally aspirated K24 setup. One word, boost!<\/p>\n
