All engine machining is done inhouse so we can maintain full control of each and every process.  . 5 Axis HAAS VF3 - CNC Machining Centre (Pictured next page) We have the only 5 axis 20hp vector drive HAAS in the country - specially designed for the machining of alloy cylinder heads & engine blocks. This coupled with Renishaw Digitising system is a machine capable of producing any item fast & accurately.  We use it primarily for the machining of our aluminum cylinder heads which are on the cutting edge of technology.  The sophisticated equipment captures the chamber & port designs & then machines the head to a true reproduction of the original. We also use this machine for squaring of blocks, decking, clearancing, boring, machining of piston tops, flat milling and 3 dimensional milling. Winoma van Norman - Crankshaft balancer  (Pictured on this page)  A balanced engine is more efficient and delivers more power & better mileage. It runs smoother & lasts longer due to less stress on the internal components. Our balancer is optical positioning & fully computerised - we balance to 0.0 gram - precision at its best. Sunnen VGS 20 - Blueprinter (Pictured next page) Our complete cylinder head valveseat & guide blueprinting machine. Long gone are the days of the 3 angle valve job. Our minimum is 5 angles.  Cylinder heads are fully blueprinted and torque plated with specially designed tooling unique only to our shop. Superflow SF600 - Flowbench (Pictured next page) For very accurate flow figures-development and diagnostic.  For flowing of cylinder heads, carburetors, manifolds, exhausts, and other intake & exhaust pieces. Winona van Norman - CBN Surfacer  (Pictured on this page)  For surfacing heads & engine blocks. Specially modified for exact material removeal down to 0.0000". Also tilt minmised so that perfectly flat surfaces are obtained. Not dished thru crutial gasket sealing areas. Depac - GoPower Engine development dyno  (Pictured on this page)  We can dyno test, tune, and diagnose an engine upto 1000HP capability.  . Brennan Racing can also provide other services such as: Lathe work / specialist TIG Welding, computerised milling, one off & production runs.  .
