Dyno - Pace Professional Engine Dyno Break-In

New Crate Engine Break-In and Dyno Testing

We now offer this professional service package with the purchase of a new crate engine. We understand that money being spent for this service is sometimes hard to justify because it is something that you just don't see or hold but never the less it has become very popular because of power gains and longevity found with proper dyno break in. We believe this procedure is very critical on a new crate engine and cannot be done in the garage due to the proper loads applied to the engine by a dynamometer.

Engine Preparation

• All external engine bolts, fasteners and pipe plugs are checked for proper torque spec.
• Pipe plugs are added as needed.
• Bolt holes are checked with proper bolt size.
• Cylinder head bolts are checked for proper torque spec. Bolts are NOT re-torqued but checked slightly below spec (excludes any fasteners requiring torque angle procedure).
• Harmonic balancer is checked for exact TDC (top dead center) location and timing pointer is modified/adjusted to correct location. We commonly see up to a 4 degree variance which can cause internal engine damage.
• Install oil filter and fill crankcase with break-in oil.
• Engine is fully primed with oil.
• Rocker arms and valve train is adjusted.

Engine Break-In

• Engine is installed on the dynamometer.
• Cooling and fuel system is filled and checked for leaks.
• Engine oil level is re-checked.
• Engine is started and timing is set to manufacturer's specification.
• Engine is run with various loads applied by the dyno. This eliminates ring chatter which can cause non-repairable damage to the cylinder walls.
• Engine is run approximately 30 minutes or more and then allowed to cool for final inspection prior to performance dyno pulls.

Dyno Performance Pulls

• A minimum a two performance pulls are performed to provide comprehensive dyno sheets, which are included with your engine.

Repackaging and Shipping

• Any openings to the internal parts of the engine will be covered or plugged.
• Engine will be bagged and sealed then installed in a shipping container.
• Engine dyno sheet, invoice and any other documents will be bagged and attached inside shipping container.
