Services We Offer

Engine Dyno

Our enhanced Stuska dyno has an accurate Dynolog aquasition system and a repeatable test cell to handle the requirements of all types of racing engines. Pro Stock, Super Stock and Competition eliminator engines. Fuel Injected, Supercharged, and Marine applications are commonly tested. We can test almost anything with a flywheel, Ford, Chevy, Chrysler, Nissan, Toyota, Subaru just to name a few.

We monitor all important parameters including fuel flow and fuel returns, air fuel ratios (up to eight of), exhaust gas temperatures (eight of), bsfc, spark and ignition curves, individual cylinder timing, Blow By and of course correction factors for weather compensation. We can monitor and record over 50 channels.

Engine Balancing

Complete engine rotating assembly can be balanced on our T & S Engine Balancer. Internal or externally counterweighted crankshafts are done on the machine including the fitting of heavy metal (mallory metal).

Honing

 

All Honing is done on our Sunnen CV616 and checked with a profile meter.

Honing race blocks are becoming a speciality on its own as the perfomance limits rise to a new level. The use of proprietary hone stone sets and procedures for honing these blocks are becoming common place in the engine building community. There are many ring manufactures today wanting special bore finishes, there is power in ring seal. Ring seal is the most crucial part of the breaking in procedure of a race engine. From the R & D on the dyno we now know what finish we need on the bore to suit each application.

Boring & Sleeving

With our Centroid CNC Machining Centre we can bore your engine and correct cylinder bore alignment to the crankshaft and Bore Spacing. Also can bore steps for flanged sleeves and fit repair liners to damaged cylinders to reclaim blocks back to their original state.

Block Trueing & Machining

block machine Our Centroid Machine allows us to square the decks and set the heights on your race block then true the bores, before your block goes to through Honing procedures.

Lifter Bore Bushing (incl key way bushes)

Lifter Bore Alignment and Bushing using our Precision Products A45 bushings is done for a couple of reasons.The common one being to correct the position of the lifter and the oil clearance. The second is to repair oiling problems on some engines,( eg 308 holdens ). In stock we have .845", .875", .904" and .937" Jesel Keyway bushings.

 

Cylinder Head Reconditioning

A Newen Countour is our choice of Cylinder Head and Guide equipment. As well as normal three angle valve seat reconditioning we also can program unlimited amount of Valve Angles and radius's to suit the racing head bussiness. A Sunnen VGS20 Machine is used to Bore and fit Bronze guides, then Hone finish to clearance using the sunnen valve guide hones, Machine and fit Burrillium valve seats, machine guides for seals and spring pads for clearance without removing the head from machine.

Conrod Resizing & Honing

Conrod resizing and cap maching is done on our Sunnen Cap Grinder and Sunnen Hydraulic Conrod hone. We also clearance piston to wrist pins on all popular race engines, resize small end and fit small end bushes to repair worn conrods.

Aluminium Welding

All alluminium welding on site is done using a Miller Syncrowave 250 Tig. We also have torches to fit inside ports to repair cracks etc.

Sheet Metal Intake Manifolds

Manufacturing of Sheet Metal intake Manifolds for our Race Engines are also done in house, we are able to use sheet metal runners or more commonly billet runners which are becoming the norm in the competitive world of Drag Racing.

Cylinder Head Porting

Porting is done in house using a Centroid 5 Axis Porting and Digitizing Machine.

Sonic Testing

We are able to measure the thickness of metal in areas that can't be accessed for direct measurement, the most common being cylinder walls. Just like a radar gun, the sonic tester sends out a sound wave and then calculates the thickness of the metal by measuring the time for the reflected wave to return. Without any access to Sonic Testing, individual cylinders can be significantly thinner on one side to another due to the reboring process. Once the thickness of the cylinder wall has been determined a factual decision can be made about the suitability of the block for the proposed reboring procedure.

 

Surface Finish Testing

The quality of machined surface is characterized by the accuracy of its manufacture with respect to the dimensions specified by the designer. Every machining operation leaves characteristic evidence on the machined surface. This evidence in the form of finely spaced micro irregularities left by the cutting tool. Each type of cutting tool leaves its own individual pattern which therefore can be identified. Alternatively surface finishes imparted by shot blasting, shot peening, Electro Discharge EDT, or other plating operations impart a specific surface finish.

  Line Boring Blocks

We have two machines to Line Bore Blocks, one is a Winnona Van Norman and the other is a BHJ Race Block Line Borer for Mains and Cam Tunnels. Rigid enough to Bore a Cam Tunnel out from Std to 70mm . All tolerances being held to .0001"

  Line Honing

All Line Honing is done with our Sunnen CH100 line Hone , and is used on all our Engines to Recondition the Main and Cam tunnel when overhaulling our Race Engines.
