Welcome back to our NSX blog as we showcase the final build chapter of our Time Attack contender for the 2021 season! The car has found a new home for the past couple of months at Motion Motorsport as they piece together our brand new Skunk2 Racing<\/strong> K24 block and mated it up with a Kraftwerks C38-R<\/strong> supercharger kit! If you want to take a more in-depth look at what upgrades our 2021 build has, then make sure you check out the previous instalment of the blog, here<\/strong><\/a>.<\/p>\n

Since installing our previous batch of upgrades we\u2019ve had some even more go faster bits put on too! Turbosmart<\/strong> helped us out with controlling boost with their state-of-the-art Gen V Race Port Blow-off Valve<\/strong><\/a>, which is a compact unit that\u2019s 50% lighter and 25% smaller than other variants on the market. All this whilst flowing 330CFM (cubic feet per minute) \u2013 making it the highest flowing BOV of its type on the market. We also utilised their Gen V HyperGate external wastegate<\/strong><\/a> too so that we can run boost by gear. With extended thermal performance, fatigue resistance, extensive user configurability and best in class flow performance, this is the high flowing gate of its kind available on the market!<\/p>\n

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

With the NSX\u2019s engine bay busier than ever, we knew we were going to see a rise in temperatures, so we sent our exhaust off to have a performance thermal coating. This delivers the ultimate thermal barrier for our exhaust and keeps temperatures down by up to 33%. It\u2019ll also ensure that vulnerable components located near the exhaust remain protected.<\/p>\n

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

We\u2019ve also made some changes to our fuelling system so that we can run a mix of pump fuel and Sunoco E85 racing fuel<\/strong><\/a>. One of the reasons we\u2019ve made the switch to E85 is that due to its alcohol type-fuel, it offers a cooling effect for the engine whilst creating more torque and horsepower than regular pump fuel, whilst helping to prevent knock too.<\/p>\n

As mentioned in our previous blog, we enlisted the help of Andy from ICEFAB<\/strong><\/a> to fabricate some bespoke cooling solutions for us along with an array of custom brackets and splitter mounts too. It\u2019s fair to say he absolutely smashed it out of the park with his custom charge cooler, radiator and oil cooler.<\/p>\n
