Vintage engine testing equipment that can test ignition timing, ignition dwell, manifold vacuum and exhaust emissions. Engine tuning is the adjustment or modification of the internal combustion engine or Engine Control Unit (ECU) to yield optimal performance and increase the engine's power output, economy, or durability. These goals may be ...
Car tuning is the modification of a car to optimise it for a different set of performance requirements from those it was originally designed to meet. Most commonly this is higher engine performance and dynamic handling characteristics but cars may also be altered to provide better fuel economy, or smoother response. The goal when tuning is the ...
Not every vehicle upgrade will increase its value, but some will. As an added bonus, certain modifications will add both to your car's aesthetic and functional value. Check Out: 10 Cars That ...
These "bolt-on" modifications alter the way that the engine flows, often causing the air to fuel ratio to change. Without re-mapping the fuel tables, some of the performance gains from the modifications may not be realized. A poorly tuned electronic control unit can result in decreased performance, driveability, and may even cause engine damage.
Upgrades included a US$37,000 engine upgrade that utilised enlarged cylinder bores, and longer stroke to increase displacement from the stock 488 cu in (8.0 L) to 514 cu in (8.4 L) along with forged steel connecting rods (titanium rods were an extra $3,500) and forged aluminum pistons; the whole assembly was then balanced and blueprinted to ...
A cylinder head of a four valve Nissan VQ engine engine. A multi-valve or multivalve engine is one where each cylinder has more than two valves (an intake, and an exhaust).A multi-valve engine has better breathing, and with more smaller valves (having less mass in motion) may be able to operate at higher revolutions per minute (RPM) than a two-valve engine, delivering more power.
