What is it?
Company owner and former aero engineer Graham Heane has been working on an engine conversion for Aston’s early 4.3-litre V8 Vantage since 2010. Identifying the strong supply of affordable used Vantages that currently exists, sharing the same appreciation of the baby Aston’s charms that so many feel, but aware of the limitations of early cars too, Heane has developed a low-impact, low-pressure supercharger installation with a twist: a proprietary water-injection system.
Running with just 6.5psi of boost pressure, a special ECU and a leaner fuel-to-air mixture than standard, the 4.3-litre GMR 600 Vantage trumps even the new Aston V12 Vantage S for power – developing a peak 573bhp along with 445lb ft of torque from 3500rpm. The conversion on newer 4.7-litre engines puts peak power above the 600bhp threshold.
Aston’s 0-60mph claim for the last V12 Vantage was 4.1sec. For the current one, it’s 3.7sec. This V8 will do it in 3.6sec; less on an absolutely perfect run. And the conversion costs £20,000 including VAT - on cars widely available used from just £30,000.
