In Part 1 we gave you tips on how to make an older car a keeper with simple, universal upgrades that can add better performance and fuel economy to any ride. This time we finish up the two-part series with parts that add safety and further enjoyment. Honest.
Team MotoIQ in conjunction with 5523 Motorsports and Specialty Cars Fabrication set a new H/PS land speed record at the Bonneville Salt Flats during the recent USFRA World of Speed event. Their experience on the salt however was not entirely drama free.
The NSX’s stock 155lph fuel pump reportedly maxes out around 400whp which will not suffice for our turbocharged 500whp+ goal. We upgrade the factory pump with the new Walbro 416 E85 compatible fuel pump and visit our friends at Brown and Miller Racing Solutions for motorsport-grade alcohol approved fuel lines, fittings, and electrical wiring. We finish the build by taking our hanger to be PTFE coated by Calico coatings.
Everyone who has been reading MotoIQ has heard me say it time and again, heat = energy. Why is this especially important with turbos? Because the turbine wheel in the turbo takes energy out of the exhaust flow to spin up the compressor. The more energy available for the turbine to grab means there is more energy to spin up the compressor. Here is the proof.

We are often times asked why our stainless mandrel bends and tubing is expensive compared with our competition. There are several reasons including the fact that we use US-sourced ASTM certified tubing (in some rare cases we may use a Canadian or Japanese sourced product based on availability) and that we use the utmost care in the mandrel bending process.
The 2014 season has not been an easy one so far but the first podium and win came for Darren McNamara and Team Falken at Formula Drift Round 5 Seattle. Darren had to go up against his teammate Daijiro Yoshihara in the Falken Tire BRZ in top 16 but the real challenge was the battle against Chris Forsberg in the final four and of course the controversial tandem against Dean Kearney in the final.

Dave Coleman told you how to figure out how old your tires are by looking at the date code. He also mentioned that older tires tend to be greasy when you push them to the limit. However, there's one other thing he didn't mention that's rather important when shopping for used tires.
Maxxis has been in the tire game for a long while, but only recently have they jumped into the road race DOT R-compound market with the RC-1. The goal for the tire was to be an all-around performer as well as being durable and affordable. Such characteristics will appeal to all crowds of motorsports whether it is wheel to wheel racing, time attack, or HPDE (high performance driving event) "track days". The size availability covers a lot of the more popular ranges, with some niche sizes that will be out shortly. The test vehicle was my own project 370Z, which represents a street car that gets tracked often being the norm for the majority of HPDE attendees. Project 370Z is a full weight, relatively softly sprung, daily driven car. So the RC-1’s had their work cut out for them in the wear and heat cycling capacity department. Also, Project 370Z is driven to and from the track on the tires it uses for the event since I have only one set of wheels for the car. So I have to get the tires mounted the day before I leave for events and changed back after the weekend which is a scenario that a significant amount of track day goers deal with regularly.
If you follow us on our Instagram or Facebook page (and if you don’t why the F not? seriously, click up there on the top right of the page and connect!) you know we received one of the first batch of FD RX-7 Rocket Bunny kits to come into the states! If this seems out of character for us, it is—never in our history have we put a bodykit on one of our project cars—and for good reason, most of them look terrible, are molded poorly and are difficult to install.
Each year before Speed Week, it seems like we face some serious obstacles in our speed week preparations. But each year, the team pulls together and manages to cheat Murphy’s Law of its satisfaction. This year has been no different.
I am wearing a Casio G-Shock watch that dates back to the late 1980s—it was one of the first models with a full stainless steel case under the thick plastic bezel. I recently purchased it online in a fit of nostalgia—it is a twin to the one that I had back in college. It’s a cheap way to relive my youth, but what’s really cool is that the watch has an aftermarket reproduction bezel. The originals are no longer available from Casio and some enterprising folks made new ones.

One year ago, the American Le Mans Series and the GRAND-AM Rolex Sports Car Series were at this very track, Road America for the first and only time together as two separate series. This year, Road America played host to the newly formed combined series of TUDOR United Sports Car Championship.
It's time to think about suspension. Some of the most common handling problems that you are the most likely to see on modified street cars and race cars based on production chassis, especially in racing classes that do not allow relocation of suspension pick up points are bump steer and toe steer related handling issues. Bump and toe steer can have significant negative effects on a car's handling which is manifested by steering pull, twitchiness, instability, steering inaccuracy and unpredictability. All of these things are scary for drivers to deal with.
