911 GT2 RS vs Camaro ZL1 1LE - Sweating the Details

By
Blasphemy!! Before you get your pitchforks, let's get two things straight first of all. Number 1, those two cars are not actually going to be cross shopped. I get that and don't mean to suggest that they would be. In fact, even for those people who can afford to buy several of either of those cars and would not turn their nose up a Chevy Camaro (they do exist), if any were to consider both those cars, they would not be looked at as alternatives, just two separate interesting cars. Number 2, stock vs stock, on the same day, same track, same (experienced) driver, the Camaro does not stand chance. Don't get me wrong, the Camaro ZL1 1LE is very impressive and supremely capable. More so when you consider the price. Even more so when you consider that this isn't like the last Z/28 or GT350R. As much as all the aero bits would have you believe, one of the ZL1 1LE's goals was to retain full functionality. As a result, it doesn't lose any sound deadening. You get to...

Porsche Cayman GT4. Driven. On Track.

By
Cayman GT4 On Track at AMP - Graham MacNeil © It's a crisp, dry Sunday morning; the second day of the annual two-day BMW Club Atlantic Advanced Driver Training (HPDE) in August. The first day was very rainy, which did make it very educational and fun, but it wasn't the day to make speed. Sunday was shaping up to be a good day for that, and I had a lot more to look forward to than just making speed.. Because the tool by which I would be making that speed (at least for one session of the day) was not my sledge hammer. It was a scalpel, a Porsche Cayman GT4. You may be wondering how I got to drive one in the first place. Let's rewind a bit for that. Last year, a gentleman at our local track asked me if I want to come out for a few laps with him in his car, a Cayman GT4. Obviously, the answer was yes. I wrote about that (original post  here , if you want to read). Fast forward a few months to when I had that post featured front and centre in my updated blog layout, ...

Limited Slip Differentials - The Basics

By
I'm finishing up a comparison post (link to introduction: Intro: Focus RS vs Golf R vs WRX STI vs Evo X ) and, throughout the post, I realized that I have to go off topic a lot to talk about how each type of differential changes the way the car drives. As a result, I thought I'd write a separate post to go into more detail before I post the comparison to keep it more focused on the cars and avoid veering off topic too much. By saying "Limited Slip Differentials" in the title, I am including torque vectoring diffs because, although current conventional terminology treats them differently, a torque vectoring differential is, in essence, a very sophisticated limited slip diff (LSD) that can be manipulated to actively help the car handle better. And while none of the cars in the comparison use open (without help from the brakes) or non-gear mechanical LSD’s, I’ll briefly discuss them so that the post is more inclusive. I’ll only focus on using power to help the...

2016 Mustang EcoBoost Track Review

By
Photography by: Graham MacNeil Ford really wants to sell you a Mustang with a turbo four cylinder. They started by derating the V6 engine in the 2015 S550 compared to the 2011-2014 S197 V6 to make the EcoBoost 2.3 litre more differentiated. Then, they offered a performance pack on the EcoBoost but not on the V6. Now, they killed the V6 all together for 2018 and will only sell you a V8 or this EcoBoost. I love a good V8, everyone who knows me knows that. This is a Mustang, which means it needs a V8. If those aren't enough reasons, I always prefer natural aspiration over forced induction. That's three strikes against the EcoBoost-powered Mustang. But I'd be lying if I said the idea never intrigued me. It's the lightest (if you account for features). It has the best weight distribution. It has the same great chassis as the GT. It's very affordable and it has a lot of potential to make more power. Aftermarket? Endless support. There's plenty of good about it....

Kawasaki Ninja H2R - 300 hp and Supercharged

By
Okay, this isn't a car but there's a reason why I'm writing about it. It has a supercharged 1.0 litre engine makes 296 hp. 296 hp may not be too impressive in a car but one has to remember that this isn't a car. It's a bike and it weighs just 476 lb in full trim and a 90% full tank. That's a weight to power ratio of 1.6 lb/hp. I'm having a hard time wrapping my mind around that number. To put that number into perspective, a 2013 Mustang GT500 has 5.9 lb/hp. A C6 Corvette ZR1 has 5.3 lb/hp. A 2015 Porsche 918 has 4.2 lb/hp and that's with the electric motors running at full song. The insane Hennessey Venom GT with its twin-turbo LS7 7.0 litre engine has 2.2 lb/hp. I can't even begin to imagine what 1.6 lb/hp would feel like. I would also be curious about how fast you'd have to be going to be able to use that power. I used to have an 09 Cobalt SS. It had GM Stage 1 and a few bolt ons which would put it at very close to that 296 ...

GTR vs Evo X vs STI: which has the best AWD system?

By
A few weeks ago, I made a post explaining  mainstream AWD system types and how they compare , pros and cons, etc. including some simple diagrams to show where the power goes and how much. As promised, this post will focus on specific cars and what AWD systems they use, especially ones that that have more or less been defined by their AWD systems, and the best place to start may be with a bombshell; the Nissan GT-R. Nissan GT-R (R35) The GT-R has built a reputation around having monster traction and very approachable performance, thanks to its AWD system - Advanced Total Traction Engineering System for All-Terrain (ATTESA) - and what it can do for you. But the GT-R doesn't actually use the most mechanically sophisticated type of AWD systems discussed in the previous article, namely a "true" AWD with a centre differential. Instead, it uses a clutch pack to transfer power. RWD-based clutch-type AWD schematic - Rams Eye The Track Guy © The R32, R33, and R34 Sky...
