 Track day Chimaera: more power required! |
TVR Power reports that its supercharger project is progressing well, and that partner AutoDesign has finalised the system design.
TVR Power has also reported that it's built two prototypes. It's installed a stock 4.0 litre engine into a Chimaera and is finalising the changes to the plenum area to accommodate the supercharger intake. To reduce under bonnet air temperature and radiated heat to the supercharger installation, the exhaust manifolds have been ceramic coated. An added benefit is reduced heat transfer to the car interior so drivers benefit from a cooler cockpit, especially in the summer months.
There's also an installation in a Griffith 500. according to the TVR specialist, the engine is built and waiting for installation into the TVR Griffith 500 prior to mapping of the engine on the new 1500 hp capacity dynamometer (see below).
- Engine capacity increased to 5.1 litres with reduced compression ratio.
- Cross-bolted engine block with forged pistons, con-rods and balanced crank.
- To maximise air volume within the combustion chamber, the intake runner length has been optimised to increase air compression and to tune peak power and torque to the objective RPM.
- New plenum for improved engine response.
- Steel rockers with camshaft optimised for supercharging.
- Higher rate fuel pump, rising rate regulator and high flow injectors
- Light weight flywheel with triple plate race clutch and centre mounted hydraulic release bearing.
- Ceramic coated exhaust manifolds.
- Rear differential gearing changed to a higher ratio, this potentially increasing the theoretical top speed towards 180 mph.
Preliminary studies are being carried out for installation of an intercooler with a planned completion date of June.
This follows TVR Power's announcement in January that together with automotive design consultancy Autodesign, it would offer a supercharger upgrade for the Rover V8 -- serpentine or pre-serpentine -- that could boost the engine's power to 500bhp.
New dyno
TVR Power bought a rolling road in January to allow the company to fine tune its engine packages and quantify the effects of its work both in-house and directly to customers. The new Dynojet 224XLC can measure up to 1,500 horsepower according to TVR Power's Web site and features its own weather station to eliminate any variations caused by atmospheric conditions.
