While these aren’t necessarily Jeep mods, they should be checked and double checked when you’re putting in work. No matter how careful of a driver you are, there are likely going to be times when you get yourself into a bind. Even if it never happens to you, others who you come across or go adventuring with may need help.
Put it all together and you have the monstrous mill that propelled the 2009 ZR1 to 60mph in 3.2 seconds, 100 in 7 seconds, and covered the quarter mile in 11.3 at 131 mph. Keep in mind this isn’t the spec list for a 2013 Gallardo, this was a 2009 Chevrolet Corvette. An all-aluminum supercharged V8 in a 200-mph American car that was faster than a GT-R, in 2009.
On paper, the Toyota Sienna seems to offer everything. It is roomy and has plenty of cargo space. Unfortunately, what looks good on paper isn’t always good in real life.
They’re even saying it will beat the old ZR1’s Nurburgring lap by a full 20 seconds. And if the current GM Performance Catalog is any indicator, in a few short years you’ll be able to stuff either one of those engines into your grandma’s old woody wagon. What a time to be alive
Let’s start with the 9.1:1 compression, which means you can run this on pump gas. Add in a cast aluminum block, titanium valves, and a forged steel crank attached to forged titanium rods attached to forged aluminum pistons. Top that off with hydraulic roller cams, aluminum heads, and a high-helix supercharger pushing 10.5psi of boost.
Enter the LT4 crate engine. Power comes on fast: a 1.7-liter Eaton supercharger spins at 20,000 rpm to force 9 pounds of boost into this 6.2-liter engine. That results in the same 650 horsepower and 650 torques you’ll find in the Z06 that’s sitting over at your local dealership, but for a fraction of the price.
That’s right, in the GM Performance Catalog of crate engines an 8-liter V8 is considered “small”. With max revs set at just 4500rpm, the Vortec 488 is a mill designed not to power the car you’re racing, but the truck you’re hauling it with. With 375 horsepower and 475 lb-feet of torque on tap at only 3200rpm, the 488 can tow that high-dollar enclosed trailer without breaking a sweat. Or it could pull your boat, your cattle, your neighbor’s house, or the grandstands at your local dragstrip. You get the idea.
That didn’t stop this shop from stuffing the lower-compression street version into a 2012 GMC Sierra single cab truck, a vehicle which, as you may know, has almost no weight over the rear wheels. That must be a hoot to drive.
