HENNESSEY MCLAREN 12C HPE700
Texan tuners follow up twin-turbo Ferrari 458 conversion with comparable upgrade for McLaren 12C
Thing is, does this give you P1 pace for $19,000, rather than the $1,150,000 McLaren is asking for the hybrid hypercar? And, more importantly perhaps, does it mean you can out-drag your mate who's just added Hennessey's HPE700 turbo package to his 458?
Hennessey claims a 2.8-second 0-60 time, matching that recorded for its turbocharged 458 and the quarter-mile times are barely two-tenths apart (10.3 for the McLaren) with terminal speeds matching at 137mph. So they're still evenly matched, just a little further down the road than the stock versions. By Hennessey's own VBOX acceleration tests the uprated car is a second faster 60-130mph at 7.15 seconds than stock and "flat out, scalding fast" according to Hennessey's communications manager Doug Kott.
Hennessey's website but necessitating a water/methanol injection system to cool the charge air at high boost pressures to reduce the risk of detonation. This is managed by a piggybacked ECU upgrade, new air filters, a new exhaust system and modifications to the heat exchanger cooling systems.
And beyond surprisingly tasteful badging that's it...
