ACR 4.0 DAKAR ENGINE 265 BHP 262 FTLB

ACR 4.O DAKAR.  Based on the Thor engine, this spec includes our heavy duty top hat liner system to eliminate the cracked block problem.  Fitted with our CNC ported big valve heads, reworked intakes etc, this engine produces 265 BHP, a significant increase over the original Bowler high spec engines, which show

235/240 BHP on our test bed.

4.6 SPORTS ENGINE   278–282 BHP @ 5400 RPM, 289 ftlb @ 4700 RPM

Designed for smooth broad power band, this engine gives strong torque from 1200 RPM.  Included in this specification is our top hat liner system with 94mm bores, 9.75 CR, Stage 2.1 CNC ported big valve heads, pocketed pistons, reworked and shortened 45mm intake tracts and flowed plenum chamber, vernier duplex cam drive and hydraulic camshaft. Engine fully assembled with sump, rocker covers, front cover/oil pump, and can be specified in either Serpentine or Gems configuration.  This engine has had notable competition success and is a favourite with the top competitors in National Championships, including Hill Rally Championship winners Tim Dilworth and Anthony Brinkman.

4.8 SHORT STROKE SPORTS.  299-304BHP @  5600 RPM, 294 ftlb @ 5250 RPM

Built to a similar spec to the 4.6 Sports but with our own forged 96mm bore pistons. The 4.8 is an excellent choice, giving a very competitive balance between power, torque and cost

Outright sale              £5662.00

5.0 SPORTS 308-312 BHP @ 5900 RPM 318 ftlb @ 4300 RPM

Built on the favoured short stroke big bore format (96mm x 86.3mm) with fully heat treated offset ground crankshaft, I beam billet rods, and hyper eutectic alloy pistons, the 5.0 gives effortless torque and smooth running and has a big advantage over the long stroke varieties such as TVR 500 engines, as the 5.0 short stroke can stand higher RPM and hence offer a big power advantage.

5.0 WILD CAT ENGINE 370 BHP @ 5950 RPM, 340FTLB @ 5600 RPM

The Rover cylinder head design is ultimately the limiting factor when it comes to power on the V8 engine. If you need over 350 BHP you need the Wild Cat!

Tweaked again further for 2006 this spec now includes 47mm crossover throttle bodies for even better flow, CNC ported heads, 96mm big bore top hat liner block, roller rockers, solid cam, camshaft and 10.7:1 CR
