Mustang Shelby GT350 - Legendary Name Brings Legendary Power




It's old news by now but I can't see my blog not having a post about this.. I'm a big Mustang fun. It's the highest revving, most powerful and most power dense production engine in Ford's history. Need more superlatives? It's also Ford's first flat-plane crankshaft and the world's largest flat-plane crankshaft V8. It also has another achievement to add to its portfolio. At 526 hp, it makes over 100 hp/litre.




It will make its peak power, 526 hp, at 7,500 rpm and a peak torque value of 429 lb-ft at 4,750 rpm which gives it a healthy hp and torque peaks spread of 2,750 rpms. Moreover, 90% of peak torque is available from approximately 3,450 rpm and 7,000 rpm. Optimizations have been made everywhere to ensure the engine is always happy to go around a track.

As everyone now knows, the engine will feature a plat-plane crankshaft to improve engine breathing. It does so by separating cylinder banks exhaust pulses (i.e. you can't have two cylinders on opposite banks in the exhaust stroke and pushing exhaust through the exhaust pipes). The engine will be mated only to a Tremec TR-3160 six speed manual (as it should be). The transmission is specifically engineered for low mass and the high rpm application of the GT350 and GT350R Mustangs. It features a lightweight aluminum case and clutch housing and optimized gear cross-sections, dual mass flywheel and dual-disc clutches, all in the name of reducing weight and inertia.

Other unique features of the new 5.2 litre V8 include a slightly oversquare bore and stroke of 94 x 93 mm and a high 12.0:1 compression ratio. The cylinder heads are CNC machined, the intake valves are hollow stemmed and the exhaust valves are sodium filled. Both valves can be lifted a significant 14 mm. Feeding air to the engine is an 87-mm throttle body, the largest Ford has ever fitted to a production engine.

A unique new aluminum engine block featuring Ford’s "patented plasma transferred wire arc cylinder-liner technology" is lighter. This process allows Ford to eliminate heavy iron cylinder liners with a deposition process. The flat-plane crankshaft is forged and is “gun drilled” to reduce total engine weight. A lightweight, high-capacity baffled oil pan is designed to sustain high g-forces in high-speed cornering and hard braking. Ford says even the intake is simpler and lighter. Everything has been optimized. Can't wait to see it in person? Me neither. Here's something that should help; some sibling rivalry between a GT350 and a GT350R out on the track.

550 hp V8 Cadillac CT6 V Coming in 2019

Cadillac's largest car - the not-quite-a-flagship CT6 - is becoming a little more flagship-y by getting the full V treatment like you can get on the CTS and ATS (for just one more year before they're axed in anticipation of replacements, so grab them while you can). Cadillac calls the CT6 top-of-the-range but won't call it a flagship, clearly wanting to leave that distinction to a larger and/or more grandiose vehicle in the future. It was previously announced in March earlier this year to be getting a high dose of performance enhancements, the highlight of which is a new twin-turbo V8, and was going to join the line-up as Cadillac's skim-V models called V-sport. Think of it like M-performance packages from BMW vs full fledged M models, the only difference being V-sport models typically get unique (and much more powerful) engines. But just a couple of weeks ago, Cadillac announced that it will make it a full-fledged V line model, making the car inch a bit higher in pre…

2020 Mid-engine Corvette C8 - What You Need to Know

Rumours of a mid-engine Corvette have been around basically since the C2 Corvette, the first Stingray. I've heard some people argue that the Corvette is already mid engine because the engine sits almost entirely behind the front axle, making it mounted midship. But everyone knows that the classic definition of a midengined car is that of an engine mounted between the seats and the rear axle, not the front axle. That's what everyone pictures if you say "mid-engine". Worse still (for the Corvette), a true midengined layout has a lot more traction - all else being equal - than a front-midship mounted engine like the current Corvette, no matter how far back it is mounted. Chevy knows this, and there has been no shortage of Corvette mid-engine concepts for decades. This time, however, it's different.

For one, manufacturers these days tend to keep very special/high performance models under wraps for a very long time during development, only revealing them when they a…

2007 Saleen Mustang S281 SC Super Shaker Track Review

"Who's your green student today?" asked a friend and instructor at the BMW Club Atlantic Advanced Driver Training (HPDE) weekend in June this year. I said: "The Saleen." The response was: "Oh, boy." Mustangs, generally, have a reputation for being more power than chassis. Mustang drivers have quite the reputation for.. how to put this nicely? Taking advantage of said power/chassis imbalance. To make matters worse, this particular Mustang was a supercharged Saleen, with a honkin' Shaker scoop sticking out of its hood. Did I mention it was also a convertible? And the owner was someone who's never been on track before but clearly has the speed bug.

Having had a Mustang for years and driven a few on track, they don't scare me - generally speaking - but the combination of being convertible and supercharged with a new and excited owner worried me a little. Nevertheless, I shrugged it off and got excited about chatting with the owner to find out…

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. 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 loads. Combine that with the fact that I drive a good amount on the street during the summer, and I was very worried that they wouldn't last more than a handful of…

Michelin PSS vs Firestone Indy 500 - Track Review

A couple of weeks ago, I posted my first impressions of Michelin's PSS vs Firestone Firehawk Indy 500 tires. I've run PSS's for several years on the Boss, but I'm trying the Indy 500's for the first time. In short, I was worried about the narrower tires (I was running 285/35/18 PSS but could only find the Indy 500 in 275/35/18) and tread squirm, but I was happy with them up to that point just driving on the street. I had the chance to drive on them for three track days now. So what were they like? After my first session, they made an impression that basically persisted for the rest of track sessions on them. Phenomenal, unmatched value. Now, if value is something that stands out above all else, it typically means the compromise between qualities you want and those you don't is less than ideal, but the value is attractive. This is no different. I'll start with the bad, which really boil down to two: ultimate grip and grip longevity.

Grip is noticeably lowe…

2014 BMW 335i xDrive M Sport Review

Post-refresh 2015 F30 3-series pictured. 
Which is better, an F30 3-series or an E46? The F30 has certainly taken its fair share of heat. But if you thought I was going to say the E46, you'd be dead wrong. The F30 3-series is better. Far better. It is quicker, faster, safer, more practical, more efficient, more refined, quieter.. the list goes on. A lot of reviews and people I talk to consider the F30 to be an abomination. Frankly, I don't see it. You'd have to be mad to think the E46 is better. Completely out to lunch. I don't know who in their right mind would prefer the E46..  Trouble is, since when were people buying sports cars in their right minds? Here, lies the real problem.

"Raw rather than refined in its noises, pounding ride, heavy clutch, 50 grand and cloth seats?"
".. and not at all shy about its performance compromises. It always acts like the automotive jock it is, every mile of every day."
"Raw and quite loud.. And sometimes ru…
