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.
Learn what works, or doesn't work before wasting valuable time and
money trying to tune and diagnose at the races.

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). |

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. |
 |
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. |
 |
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 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. |

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