A Solution to a long term problem

A special report in the spot light section in the totally speedway mag found that Clarko’s Performance now has hi rise rocker covers to suit the Ford 250 / 4.1 cross flow 6 cyl alloy and cast iron cyclinder heads, rather then adding a spacer to the EFI styles or having to cut up 2 steel rocker covers, why not just have a purpose made cast aluminium hi rise rocker rocker to suit the application?

Benefits – these are made to clear the rolla rockers
- the cover is supplied with both pcv and breather cap grommets
- has cast in cone style breather shrouds

To prevent oil leaks from rocker cover spacers and the time it takes to cut up 2 tin rocker covers to avoid the issue of the rolla rockers hitting, lets face it this is really a 1 stop solution solver.

Holden Commodore Aluminium Pulleys – Why are they so wonderful to use?

If you have a Holden V6 engine and you would want to give it an extra bit of edge, maybe you could try going for an Aluminium billet pulley. Holden commodores with Holden V6 engine in the ecotec (series 2) and non ecotec (series 1) comes custom fitted from the factory with a press steel pulley.  This press steel pulley drives the alternator, power steering, water pump and other accessories. Aluminium billet pulleys are lightweight and nicer for your engine.  These replacement OEM pulleys are made of the highest quality billet T6061 billet aluminium, which is much better than the cheaper cast aluminium or the steel ones available.

Using OEM replacement pulleys dress up your engine and are wonderful to have for show cars. These replacement OEM pulleys are useful for ecotec engine power steering, alternator, and water pump whereas reduction drive pulleys suit non ecotec and ecotec series 1 and 2 engine. They are 20% larger than the standard one available in power steering, alternator and water pump.

Replacement OEM pulleys are a replacement bolt on bolt for ecotec V6 engine (series 2). These are available in the same size as the factory-fitted holden pulleys. Hence, these can easily replace the factory ones, and you can do the replacement yourself using the same sized fan belt.

The process by which the replacement OEM aluminium pulley can be fitted is very easy is explained here: First, you need to remove the fan belt. This can be done by undoing the bolts that hold the power steering, alternator and water pump pulley. Now, remove the old press steel pulleys. Attach the new billet OEM aluminium pulleys in the empty place. Now, tighten the bolts back on. Attach the fan belt, and your engine is all spruced up.

Why must you use an OEM aluminium reduction pulley?

The main use of reduction pulleys is to slow down the RPMs (Revolutions per minute) of parts such as power steering to avoid cavitation, oil boiling and frothing, and the breaking down of the consistency of oil. These are 20% larger in size thus it is easier for them to do so especially for race cars. These are used for water pump to avoid cavitation and decrease the speed of the water that goes through the engine block and that can reduce the cooling efficiency of an engine. They are also used for alternators to avoid over revving of the alternator that can cause it to fail and stop working.

These pulleys have been used extensively in race cars such as modified production, wingless sprint cars and many other speedway classes and other race divisions available in ecotec engine  series 1 and non ecotec engine series 2.

These pulleys are especially popular and widely used in Holden V6 engines across Australia and New Zealand. They have been race tested and have a proven performance record. These are a great accessory to have for your engine

Clarko – Hollyman team up for 30/30 at Gympie speedway (may 2011)

Gympie speedway held a 30 30 for modified production in may 2011, which saw over 20 cars attend
just as the feature for the super streets was nearing completion the sky opened up and rained so the 30 30 was cancled

Never seen the Gympie track before it was a eye opener the track had a hill, hair pin, dipper and a dog leg never seen anything like it before
so this was a test,  Clarko and Luke had a ball, the car was set up for Brisbane speedway where the track gets real rutty , so we were chasing car set up at the new track. Due to rain on the last event the 30 30 was not run

Clarko would like to thank the crew at Gympie for there help
Luke Hollyman, Jason Beer and crew, Matty (the baby oil man) and crew, Kim Lucas, Peter Watling

next event Brisbane june 2011 for the 50 lapper

Wheel Spacers – Why are they needed?

Wheel Spacers, as the name suggests, are used to increase the space between the wheel and the car body. Wheel spacers are commonly made of aluminium and are installed between the car’s hub and wheel. Wheel Spacers are used for a variety of reasons:

• Better stance: The owners of cars sometimes wish for a better stance for their cars to increase the stability of the car at higher speeds especially related to the braking, maintaining the stability of the car at high speeds, or while maneuvering curves. One of the ways of enhancing the stance of your car is by increasing the wheelbase of your car. Wheel spacers are an easy-to-install option for you to achieve the same. Good quality wheel spacers are very useful for both racing cars and normal cars. They cost much less as compared to buying a set of wider tires for the same purpose. Wheel spacers help in increasing the distance between the axle and the wheel hub hence maximizing the wheelbase without actually changing the tires or the suspension equilibrium.
• Correct the incorrect offset: Wheel Spacers are also good to have when you want to install different offset rims in your car or reposition the offset of the rim of your car. If you like to do off-the-road or all-terrain driving, then wheel spacers must be used to increase the space between the wheels of the car and the car itself. This provides a safer, more stable driving experience in rugged terrains. Aluminium wheel spacers are ideal for All Terrain Vehicles as they provide an additional balance required for all terrain driving or for race cars.
• Better Appearance: Wheel Spacers provide a more aggressive, macho look to large cars. They are also utilized for better handling of the car.

Essentially, there are two types of wheel spacers: Slide-on wheel spacers and Bolt-on wheel Spacers.

• Slide-on Wheel Spacers:  These Wheel Spacers are most commonly used.  These just slide on the existing bolts. You need to simply remove the rim/wheel from the axle, slide the wheel spacer over the axle studs, and refit the rim/wheel to the axle. These wheel spacers are available in different thicknesses, ranging from 3, 6, 10 and 12 mm.
• Bolt-on Wheel Spacers: These are bolted to the car’s hub on which the wheels are then fitted. To do this, the rim/wheel is first removed. The wheel spacer is installed over the end of the axle studs. A standard style wheel nut is used to hold the wheel spacer to the end of the axle. It must be ensured that the axle stud or wheel nut does not protrude past the outside face of the bolt on the wheel spacer. The other set of holes will have the studs protruding, and the rim/wheel will be fitted here. Bolt-on wheel spacers are available in thicknesses of 35 and 50 mm.

You can also find alloy wheel spacers which come in billet aluminium or cast aluminium. Aluminium or a combination of aluminium and another alloy provides the much needed additional strength to the wheel spacer and are the most desired in the market today. The installation of wheel spacers is very simple as explained above, and your manufacturer can guide you further. Try aluminium wheel spacers for a better road performance.

Holden HQ is 5 x 120.6 mm PCD
Holden commodore is 5 x 120 mm PCD
Ford stud pattern is 5  x 114.3mm PCD
