Header/Manifold Design

Tune Your Own Custom Made Header/Exhaust Manifold

If you are serious about your all-motor power, then a custom header/exhaust manifold will be mandatory for your project vehicle. By this point your motor will be built to the limit or near-limit. You have high-compression, a ported head, different intake manifold and perhaps a different combination of bore and stroke. You have camshafts with an aggressive profile. The last of these changes, Continue reading

Vauxhall XE RWD

One of the most popular motorsport engines and one of the most popular choices for kit cars.

To identify if the engine you are looking at is an XE, the cam cover will have an L-Shaped spark plug cover on the cam cover. Even though the engine is referred to as a red top on later engines the plug cover was black.

Vauxhall XE Conversion for RWD

The full name of the XE is 20XE and was first installed in the MK2 Astra GTE followed by the Cavalier MK3 GSI, Cavalier SRi and some early Calibras. The engine wasn’t in production for long before it was modified with the new code being C20XE. It was modified for emission reasons and power dropped from 157bhp to 150bhp. The last of the line engines from 1992 an on were distributor less and used Motronic 2.8 ignition. This engine was designated as theC20XE LN.TheC20XE LNused cast pistons instead of the forged pistons used in the original 20XE and C20XE. However the block on theC20XE LNis actually stronger than the block used for the earlier engines. Continue reading

Data Logging

Data Logger & Sensor Manufacturers & Suppliers

Data Logger & Sensor Manufacturers & Suppliers to top level motorsport from the UK and USA.

A data logger (or datalogger) is an electronic device that records data over time or in relation to location either with a built in instrument or sensor or via external instruments and sensors. Increasingly, but not entirely, they are based on a digital processor (or computer). They generally are small, battery powered and portable.

Dataloggers vary between general purpose types for a range of measurement applications to very specific devices for measuring in one environment only. It is common for general purpose types to be programmable however many remain as static machines with only a limited number of changeable parameters. Electronic dataloggers have replaced chart recorders in many applications. more from Wikipedia
