2012 Mustang Boss 302 - Stock vs Heartthrob Flowpack Axle-Back Video





As promised, here's a video comparing the stock axle backs to the Heartthrob Flowpack units I installed a few weeks ago. The video shows start ups, both cold, and a few revs after the car had warmed up. The video doesn't do the difference in volume justice but you can tell the difference in tone with a good set of headphones or speakers. For a full review, go the original post: 2012 Mustang Boss 302 - Heartthrob Flowpack Axle Back Exhaust.

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

How would a Mustang 3.5L EcoBoost compare to the 5.0L V8?

Ever wonder how a 3.5 litre EcoBoost might fair against the 5.0 litre V8 in the Mustang? Of course you have. Ever since Ford dropped it in the F150 (and perhaps well before), everyone has been wondering how it would perform. There are basically two camps; those who think it would be awesome because of tuneability and power potential and those who think it means the death of the V8 in the Mustang. If you are in the latter group, we seem to be good so far with continuous upgrades to the 5.0 litre Coyote and the brand new Shelby GT500 which still uses a supercharged V8 as it has been for over a decade and multiple iterations. But what if... Well, it seems we are closer than ever to finding out the answer to that question. American Trucks recently got together two crew cab, short box, 4x4 F150's but one has the 5.0 litre V8 and the other has the 3.5 litre EcoBoost V6. There has been a few comparisons between 5.0 litre and 3.5 litre EB F150's, but this seems to be the most di

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

Juns Subaru BRZ - 2.4 litre Synergy V8

Meet Juns Subaru BRZ. If the traditional power adding methods like forced induction or dropping a small block V8 aren't your thing, this may be it (although I imagine swapping a small block V8 into something small is typically a North American - and awesome - solution, but I digress). This one does have a V8 but it's a very different kind of V8 and, at $70,000, it will cost you a multiple of that but you will no doubt have something very unique. The engine is based on two Kawasaki Ninja ZX-12R engines and has a displacement of 2.4 litres. Power? 356 hp at 10,680 rpm, a whopping 156 hp over stock, although torque gets a much more modest jump to 199 lb-ft, "only" 48 lb-ft over stock. This frankenstein engine is the work of Synery Power in New Zealand, which developed the engine for midget car speedway racing but they have wanted to put it in a street car. I would imagine the experience might be similar to a rotary engine, making a lot of power but all very h
