Exhaust Header Bash! Testing Power Loss From Dents – Engine Masters Ep. 4

Posted by

If you’ve ever installed a set of high-performance exhaust headers, then you’ve probably bashed those exhaust tubes with a hammer to get them to clear everything in the chassis of the car. It’s a super common problem, but people often worry about how much horsepower they are killing by dinging and denting those headers. This episode of Engine Masters presented by Amsoil is here to answer that for you, testing various levels of destruction of a set of Hooker headers on a 550-horsepower, 400ci small-block Chevy from Blueprint Engines.

2016 McLaren 570S: Supercar Speed with Sports Car Fun! – Ignition Ep. 145

Posted by

This new supercar costs just a fraction as much as the cars it sits next to on the McLaren showroom floor. With a sticker price of just $187,400, the 570S is nearly a hundred grand cheaper than the 650S, and it’s nearly as fast too. The cost has come down by substituting aluminum body panels where carbon fiber was previously used, and conventional suspension in place of the 650S’s interconnected hydraulic lines. The basic bits remain: a full carbon-fiber tub and flat-plane-crank turbocharged V-8 that screams to over 8000 rpm. As the car’s name suggests, the 3.8-liter engine makes 570 metric horsepower (562 SAE hp), and a new equal-length exhaust gives this McLaren a whole new sound. On this episode of Ignition presented by Tire Rack, Motor Trend Senior Editor Jason Cammisa and SCCA Hall of Fame inductee Randy Pobst test the McLaren on the road and on track to see just how much of a smile it puts on their faces....

#Rollsmokey 12V Cummins Low and Not At All Slow!! – Hot Rod Garage Ep. 34

Posted by

In this episode of Hot Rod Garage presented by Lincoln Tech, we’ve got #Rollsmokey, our 12 V Cummins Turbo Diesel swapped 1973 D200, back in the shop for a complete handling overhaul. To deal with the 750+ft lbs of torque from the Cummins engine, we had to upgrade the Dana 60 rear-end with a Detroit Truetrac, and longer 3.54 gears. To make it handle, we upgraded all the suspension bushings to polyurethane, installed a quick-ratio steering gearbox, and replaced all the bushings and joints with fresh parts. To finish it off, a set of Heavy-duty shocks, and clipped 1-ton springs were installed to get a lowered street-machine stance. Watch Tony Angelo abuse this truck before and after upgrades in a tire-melting thrash session!... Read More | Share it now!
