Here is the Golen Engine Service 12,000 Square Foot facility located in Hudson, NH. All operations from machine work to dyno testing are done in house to ensure high quality.
All of our crankshaft balancing is done on this computerized Hynes balancer. This system allows us to spin up the crankshaft with bob weights attached to find any subtle harmonic vibration. The computer then tells us exactly where to remove weight from the crank to eliminate the vibrations. All balancing is completed to within .5 gram-inch.
Cylinder boring is performed on our Rottler Boring Bar, this machine allows us to bore within .003″ of our finish cylinder size and keep it straight as an arrow.
The Sunnen HBS-1300 resurfacing machine is used to zero deck blocks and resurface cylinder heads here at Golen Engine.
After the blocks are bored and decked they next go into the Sunnen CV-616 cylinder hone, this machine allows us to finish hone each cylinder to the desired tolerance. We torque plate hone every performance engine that we build to ensure proper ring sealing.
The Bridgeport is used for quite a few operations but the most popular is for installing 4-bolt main caps onto blocks.
The Sunnen VGS-20 is used to replace and size guides, three and five angle performance valve jobs, seat replacement ect.. This machine allows us to extract hp out of the engines we build via trying different valve seat angles to increase cylinder head flow.
When the end of the racing season comes and our race engines come in for freshening this machine plays an essential part. Resizing the big and small end of the rods allows us to blueprint an exact oil clearance in our race engines.
We assemble every performance engine that we build in our clean assembly room, we have enough room to work on 8 engines at the same time.
In our dyno room we are able to test each turn key engine that we build to ensure they are running perfectly and producing the proper level of power, without the dyno it would be impossible to develop our engine packages.
