At last, we’ve reached the conclusion of the most extensive PRI 2015 coverage you’ll see anywhere. We hope you’ve enjoyed it as much as we have so far, but fasten your seat belts again because we’ve got one more, wild ride! (Technically speaking). We'll start by checking out this ridiculous, 2000+hp Nissan GTR that eclipsed the quarter mile in 7.48-seconds, along with several other crazy Pro Mod cars and the like!

The 25 Hours of Thunderhill; North America’s longest endurance race is no joke. Yost Autosport team principle Jordan Yost has always said “You have to know in January that you’re going to race the 25 Hour in order to have any chance of making it.” The race itself takes place the first week of December every year at Thunderhill Raceway Park in Northern California. Its cold and most years the race is thrown a curve ball by Mother Nature whether it be rain, fog, or both. The range of machinery spans from Spec Miatas and 100 horsepower Honda Fits all the way to factory GT3 spec race cars and top level prototypes providing an incredibly interesting race to not only watch, but be a part of, completely different from any other endurance race out there. Just finishing this race is something almost half of this year’s 65 car field didn’t accomplish.
Today, boys and girls, we’re heading back into the technical side of the Professional Awesome Evo. For your reading and viewing pleasure, we’ll be showing all the secrets in the drivetrain of the fastest Limited Class time attack machine ever to compete at Buttonwillow Raceway.
The automotive landscape is changing very quickly right now. Around a decade ago, direct injection was the big new technology to be common on the market. About half a decade ago, turbochargers made their way into the mass of vehicles sold. From what I’ve seen, the next mass play is electrification. Sure, the Prius hybrid has been around for twenty years now, but the OEMs are now launching plug-in hybrids galore. There are many more electric motors and batteries in our vehicular future.
Although the BMW E92 M3 is a fantastic car, one of the best performance sedans made, it does have a few quirks. One of them, like most late model BMW's, is that the car's systems tend to run hot. Running hot on the track is one thing, but when you peruse user forums you find that for some drivers the cars can even run hot during street driving!
By now you've probably witnessed our extensive PRI 2015 coverage, which we've separated into no less than six huge parts. There's a reason why we enjoy PRI more than SEMA, so check out this fifth installment of PRI 2015, which promises more innovative, go-fast parts with a side of more crazy cars!
Imagine a world where many of your favourite MotoIQ projects ceased to be. A world without ChumpCar or Lemons racing or many other forms of Grassroots Motorsport. That's what the EPA proposes and we need you to take action.
In the first installment of this series, we took a fairly in-depth look at valve events, which, simply put, are the actions that are caused by the camshaft with regards to opening and closing the intake and exhaust valves. Ultimately, these events determine the power characteristics of an engine, because they control the amount of air/fuel mixture that the engine ingests at any given rpm, and they also control the flow of exhaust gases leaving the combustion chamber. Hopefully, Part 1 helped you to understand the processes involved in developing a camshaft design, so at this point we’re going to discuss the terminology that directly describes the physical parameters of the camshaft itself.
The Toyota Yaris has been a vehicle that has pretty much been universally panned by the performance aftermarket. Can you really blame the aftermarket though, the Yaris was not designed for any sort of fun nor would it win any beauty contests.
Outside of the BMW and Porsche booths, there were a handful of cars which caught my attention. Of course, there were the track day toys from GM and Ford, but I’ve already shown you guys those cars back at SEMA. So what other cars caught my attention? Well, it’s an odd bunch likely due to my ADD.
You may remember when we were battling the power steering in our Project VehiCross, that the biggest reason we got so hosed (no pun intended) was I had no way of getting myself to the parts store for things like crush washers, coolant, or big buckets. With only one functioning car, we needed something else to get us around when we were wrenching on our daily driver. See how we rescued and resurrected a forgotten scooter that hadn't turned a wheel in over a decade.
And so, the PRI saga continues. If you thought we might have run out of crazy cars and new go-fast parts to show you after Part 3, stop crying. The 2015 PRI show was so packed full of neat stuff, it would have been a disservice to our readers if we'd left anything out. So sit back and relax as we continue our tour of the show!
Cleaning small parts can be a real hassle. If you’re rebuilding, say, a carburetor, with lots of little jets, needles, and pins and screws, it can be very easy to break or lose something. Some parts refuse to come clean, even when scrubbed with strong solvents (brake calipers are a great example of this). So what’s a car guy to do?
In the pages of MotoIQ, we have partnered with Pure Performance in Laguna Hills California for many of our BMW projects. Why? Because Pure Performance, eats sleeps and breaths BMW performance both on the street and through racing with customer cars and their own shop race car.
