650-HP Hellcat-Powered Mazda MX-5 Is A Thing Of Beauty

Tuning / 27 Comments

This could be the last word in engine swaps.

One criticism that can be leveled at the Miata or MX-5 is Mazda's reticence to add more power. We've seen turbocharged Mazdaspeed versions before, but the only real option left to people that want the MX-5 experience but with beefed-up horsepower has been to build the engine out, or swap something bigger in. V6 engines tend to be an easier fit while also adding manageable horsepower in a light car with a short wheelbase. They also tend to be lighter than a V8 and that helps to keep the chassis closer to the original 50/50 weight balance. However, a V8 powered MX-5 is a thing of pure and brutal beauty. A Hellcat-Powered Mazda MX-5 though, well, that's a whole new level of insanity.

This 1999 Miata is going up for auction with Barrett-Jackson complete with a 6.2-liter V8 Dodge Hellcat engine that doesn't quite fit under the hood. The engine is dyno-tuned by VMP Performance and makes 683 horsepower with 647 lb-ft of torque at the wheels. That's a long way from the original 4-cylinder's 140 horsepower that gets a bump in torque from a following wind.

We've seen this car featured on YouTube videos before, along with a claim it will touch 175 mph in fifth gear for anyone brave enough to try it. It does have a roll cage, but it would still take a particularly brave lunatic to test that claim.

The build is a complete one, and we imagine it's hilarious fun at a track. The advert claims it has "V8 roadster suspension," which we presume means the suspension comes from the company V8 Roadsters. More clearly spelled out are the Wilwood brakes, a Sparco steering wheel and seats, a BSI racing roll cage, a Treasure Coast Miata hardtop, Konig 15x10" wheels, and an AEM CD5 display for the driver to look at. It also has a heavy-duty cooling system and a welded differential with a 3.07 final drive. If you want to see "Hell Kitty" go on the block or make a bid yourself, the auction is at Barrett-Jackson's Las Vegas event.
