Saleen Grille Tested - Does It Really Increase Airflow?

730 hp Mustang Saleen 302 Black Label - Saleen © Most people who track their cars quickly come to recognize one of the biggest enemies of speed; heat. Heat affects tires, brakes, fluids, the engine, everything. One area that gets more than its fair share of heat is the engine bay. The most efficient gasoline/petrol engines struggle to exceed 35% efficiency - meaning that more than 65% of the energy in the fuel that is burnt inside the engine is not converted into motion or 'useful energy'. Most of the non-useful energy left over is turned into heat. That means that your average hot hatch making 200 hp could easily produce around 300 kW (400 hp) of heat as a byproduct of making 200 hp. If you're having trouble wrapping your head around that number, that's enough power to heat a large home improvement store. In Canada. Some of that heat goes out the exhaust (thankfully) but a lot of it has to be dealt with in the engine bay through your radiator, and oil cooler i

Can a Viper ACR take on A McLaren Senna on track?

Yes, I have mentioned a Dodge in the same breath as a McLaren, and a McLaren that was named after no one other than Ayrton Senna. You might get angry. You might think I've gone mad or lost my bearings. But before you do any of that, consider this: What is arguably the most outrageous metric or aspect about the Senna? Power? Construction? Brakes? No, in my opinion, it's aerodynamics. The power, the brakes, the suspension, the attention to detail, everything is very impressive, but none is ground breaking, especially for McLaren. The aerodynamics, though, are what resulted in the menacing and brutal function-over-form styling of the Senna which makes an Alien vs Predator battle scene look like child's play in comparison. So if it's aerodynamics, the amount of downforce must be huge (it is). You know the 911 (991) GT3 RS? It makes do with just 262 kg (622 lb.) at 150 mph. The insane 991.2 GT2 RS generates a maximum of 450 kg (992 lb.) at its 211 mph top speed. Tha

The New Shelby GT500 Is Coming in Two Weeks

If you've been paying attention in 2018, you probably already know that a brand new S550 Mustang Shelby GT500 is coming this year. And there is good reason to believe that the 2019 North American Auto Show (often referred to as the Detroit Auto Show) in less than two weeks will host the debut of the GT500. Why the 2019 Detroit Auto Show? It's one of the biggest auto shows for Ford. Ford decided to reveal its Ford GT at the same show three years ago in 2015, and also threw in the current Shelby GT350R and the current F-150 Raptor for good measure. The Shelby GT500 has already been confirmed by Ford and teased in a couple of pictures and videos. Why is the GT500 significant? The first Shelby GT500 was a 1967 model and it was developed with help from the legend himself, Carroll Shelby. Because of Shelby's personal involvement in racing at the time, the original Shelby GT500 was actually meant to be a track monster, not only a straight line car. It used a a modified versio

Can Telemetry Explain Schumacher's Talent?

With Michael Schumacher's recent fantastic news that he is no longer bedridden , I figured it would be a great opportunity to share one of my absolute favourite videos about him. I stumbled across this video last year and immediately bookmarked it. It includes bits from interviews with various F1 drivers, including Schumacher himself and team mate Johnny Herbert. But my favourite part of the video is when they compare telemetry between Schumacher and Herbert. The telemetry clearly explains where Schumacher is saving (lap) time and how exactly his talent and skills translate to better (and ultimately faster) driving. His talent is even more impressive when you consider the lack of active throttle mapping in modern F1 cars and the myriad of improvements made to driveability. Watch below to see for yourself. What I love about this video is that I found Jonathan's Palmer analysis of Schumacher's telemetry to be absolutely true when applied to my driving on track.

I Pretend My VW Rabbit is a Rally Car

Nearly lifting off at BAC Rallycross #1 2018-2019 Season - Kevin Doubleday © I hate potholes (what driver doesn't?). We are no strangers to them where I live due to plenty of rain and a lot of freeze and thaw cycles. I typically do my absolute best to avoid them. I cringe when I hit the smallest one. But when you're at a rallycross and you see... there's no other word for it, a little crater that's right where you want to be, what do you do? You pretend your car is a rally car and go for it. It might have helped that the car was cheap and I got it specifically for rallycross... If you've read my first rallycross post - The Ram's Eye is going Rallycross  - you already know I'm starting rallycross this season for the first time after finally picking up this car for it. The car is a 2007 VW Rabbit. It was the first manual car I came across in my budget that was in good running order and had proven aftermarket limited slip diff options. It has the sta

Falken Azenis RT615k+ Street and Track Review

Last year, I picked up a 2009 Lancer Ralliart to do a long term test with it as a dual duty track/daily. One of the first things I knew I was going to do was put a decent set of tires on it. The car came without OEM wheels which was actually good because I didn't have to hesitate about getting a good set of aftermarket wheels to support going wider. Thankfully, my friends at YST Auto Halifax  set me up with a great set of Superspeed RF03RR wheels. The Wheels I had never even heard of Superspeed but I trusted the good folk at YST Auto who mentioned some customer cars running on track with them. These wheels are rotary forged which is basically a prerequisite to be taken seriously in this market populated by companies like TSW and Fast Wheels. The wheels looked like a high quality, well finished wheel and each had a "QC" check sticker on. Just for appearances? Maybe, but I found no defects. The wheels seemed easy to balance (didn't need many weights) and at 18.1 lb. f

Michelin Pilot Super Sports vs Firestone Firehawk Indy 500 - Street Review

I've been a huge fan of Michelin PSS tires and exclusively bought them for the Mustang over the last four years. So how did I end up here? This year, I was hugely interested in trying an "R-comp" tire. I had my eyes set on Bridgestone Potenza RE-71R's for two simple reasons: price and reputation. Although not a true "R-comp" tire on paper, it performs like one by the account of every single test and review I've read (down to wear rates...). They seem like they're easily the most affordable (from a big brand) R-comp tire and combine that with a reputation for having tons of grip, it was an easy top contender. I had my concerns, though. For one, I'm told and have read that they are an autox tire, not really designed for high speed, pressure, and temps associated with open track. For another, the Mustang is a heavy car (as far as track cars are concerned) being roughly 3,800 lb. (including driver), which will amplify the unwanted open track load

Michelin Pilot Sport Cup 2's vs Bridgestone Potenza RE-71R's

I never thought I'd ever run Michelin Pilot Sport Cup 2's on my 2012 Boss 302. The cost is astronomical and they are supposed to last the least of anything comparable. So how did I end up with (nearly) fresh Sport Cup 2's? A complete fluke. I came across a lightly used set with only a few hundred miles and no track time; 305/30/19 takeoffs from a GT Performance Pack Level 2 (GT PPL2). I knew my 71R's were getting very worn before the season started and likely wouldn't last the whole season, even this short one. The price was far better than a new set of RE-71R's, a little more than half, and local Time Attack rules (Canadian Automobile Sport Clubs) recently made 180 and 200 TW tires equivalent, meaning no PAX or PIP point penalty for going with 180 TW tire like the Pilot Sport Cup 2's. I have been very curious about how PSC2's compare to RE 71R's but I stayed away due to their being painfully expensive and, up to last year, their 180 TW rating would

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

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
