This Chevy LT5 crate engine makes more power than two C8 Corvettes combined

Katech Performance has taken the LT5 from the C7 ZR1 and upped the numbers a bit...

Does the C8 Corvette's four hundred and ninety-five horsepower sound like a barrel of fun? What about a vehicle with twice as much power, plus another 169 small Clydesdales? If you're doing the math, that's an engine with ELEVEN HUNDRED AND FIFTY-NINE HORSES!

When you put your foot down in a car with 1159hp do the tires spin against earth or is the earth forced to spin against the tires? I asked this question to myself when I began reading about the Katech Track Attack LT5 engine. The horsepower number is impressive but what do you think of the 1063 foot pounds of torque? These mad scientists took the 'average' LT5 at 755 horsepower and increased its output by around forty percent.

How exactly did they take the LT5 to the brink of rocketship like power? Cubes, compression, and more supercharging. The Katech's LT5 mill was bumped up with some seemingly minimal numbers of an extra 13 cubes, and .2 more compression (375 to 388 cubes and 10.1 to 10.3 compression respectively).

You'll have a choice of two different superchargers - from Magnuson's TBVS 2560 or a Katech ported unit - if you go ahead and write the ultramafic-lava-like-hot check for this one. If Chevrolet is charging nearly $19,000 for the plain 'ol LT5, I can only imagine how much Katech will want for the hero-spec version.

    • Near 1:1 power to weight ratio and super short maybe even extremely super duper short drive shaft would make this fun

    • It would turn into the killer rabbit from Monte Python’s ‘The Holy Grail’. You’d be killing everyone, including yourself.

    • Saw a Mk1 with a frankenmotor 2.0 Mk1 and Mk1 combo. They HAD to take the turbos, plural, off because it was “too much”. Have never EVER heard anyone say too much was too much. But these guys were not joking. I offered the keys and title to my 02...
