Slakker/Hartech Engines - Slakker is the exclusive authorized distributor and rebuilder of Hartech Engines in the US. We have gone to extraordinary lengths to reproduce Hartech's capabilities here in the US. To support this, Hartech has provided an extensive amount of training, process documentation, access to their CNC programming code, our initial set of tooling, and ongoing support. Our Hartech branded engines start with a Hartech kit that provides all of the specialty parts that they offer and are machined and built to their strict set of tolerances and specifications right here in our US facility.
Engine Machining - One of Hartech's keys to success, and ours, has been a fully integrated model that allows us to control the quality and continued development of every aspect of the engine rebuilding process while simultaneously reducing costs and lead times. On a typical rebuild, we remove the old cylinders and open up the cooling channels in the blocks on our mill, turn the new cylinders on our lathe to the exact specification required, recondition the heads including facing the valves and regrinding the seat profiles as required, and deck the block and heads for an exact mating surface. We also have the capability for welding and repairing damaged blocks that have not been "windowed".
Testing/QA - Every engine we build goes through an extensive QA and break-in process on our Engine Dynometer where we monitor and record every aspect of the engine during testing. We use the ancillaries and the tune that the engine will be installed with to ensure that it is ready to reliably perform on the street or the track when it leaves our facility.
ECU Tuning - For capacity upgrade engines, we make the necessary changes in the engine control unit for it to adapt to the larger displacement. Beyond that, we offer custom tuning services for specialty applications such as 101 octane race gas, larger cams, or track only use.
Warranty - All of our engines include a 2 year, unlimited mileage warranty. Unlike some rebuilders, as long as our oiling and sump guidelines are followed, this warranty also covers use on the track. At the end of 1 year, an extended warranty will be available to those that want to further reduce the risk of their ownership experience (details pending).
Lead Times - We do our best to keep total turnaround time to 3-4 mos, But we believe that hurry is the arch enemy of quality. So while we can guarantee quality and budget, every build takes what it takes to get it exactly right and so the best we can do is estimate total build times.
Deposits/Billing - The build process begins with a 50% deposit. At this point, we will order all of the parts necessary from Hartech and Porsche in order to complete the build. Typical lead times on parts is 4-6 weeks. Any additional work will be invoiced upon approval. The full amount of the engine build will be billed upon successful engine dyno testing with the full deposit applied. The final invoice for the car(if applicable) will be billed upon successful drive testing.
Shipping Car/Engine - Shipping brokers can be a tough lot to deal with and so we offer logistical assistance at no charge to all of our customers. Essentially we will work through our established connections to get a shipping quote, for your approval, and then work with you on the scheduling and pickup. For cars, we will try to schedule the date for after we get all of the parts in and are ready to begin the rebuilding process. For engines only, we will generally schedule them as soon as they are ready to ship.
