The Caparo T1 engine is a 3.5-liter, naturally-aspirated, V-8 racing engine, designed, developed and made by Menard, and used in the Caparo T1 sports car, between 2006 and 2015. The engine itself is derived from the Nissan/Infiniti IndyCar engine, only slightly detuned.^[5][6][7]

Overview

The T1 sports a 116-kilogram (256 lb),^[8] 32-valve, 3,496-cubic-centimetre (3.5 L), all-aluminium, naturally-aspirated, Menard V-8, with cylinder banks mounted at 90°, and lubricated via a dry-sump oil system.^[9] The engine has gone through several designs, previously including a smaller 2.4-litre supercharged unit. The production design generates a maximum power of 575 horsepower (429 kW; 583 PS) at 10,500 revolutions per minute and a maximum torque of 310 pound-feet (420 N⋅m) at 9,000 revolutions per minute,^[10] giving the car a power-to-weight ratio of 1,223 horsepower per tonne (912.8 kW/t). In addition, the engine has been reported to successfully reach 700 horsepower (522 kW; 710 PS) on methanol fuel.^[11] The engine is controlled via a fully tunable Pectel SQ6 engine control unit and the throttle is controlled via a throttle-by-wire system.^{[8][12][13][14][15]}
