You may remember we posted information on the Hennessey 705hp HPE700 Camaro and now Hennessey continues on with this 705hp tradition by tuning the Corvette ZR1 introducing a 705hp Hennessey ZR700 Corvette.
Undoubtedly the Chevy Corvette ZR1 is Americans most powerful (native) supercar available. You thought 638hp was enough? Obviously Hennessey did not. They pumped an extra 67 ponies by increasing the boost from the supercharger by 3psi for a total of 14psi while installing other gadgets like a new intercooler, high-flow cats, stainless steel exhaust headers and a custom ECU programming. Just like the Hennessey Camaro, these parts will be available as a mail order kit later this year around May… ZR1 not included.
From these mods the performance jumps to an impressive 0-60 time of 3.1 seconds and a top speed of 212mph.
Speculation is that there will be a even more powerful Corvette ZR750 (add on kit) which will replace some internals of the already magnificent LS9 engine upping horse power to 755 with 730lb-ft of torque. That’s a serious bite!
