Owning a high-performance car often comes with a price- needing a new engine! Horsepower Research and Development can help...

Pushing the envelope on a high-performance engine will lead to failure at some point. Whether is old age, internal damage caused by component failure, or simple neglect, engine failure can be devestating. When this happens there are many many choices, from rebuilding the engine in your backyard to buying a crate engine ready to drop in. We here at HRD are very familiar with all of these choices and are here to help whatever your individual needs may be. Here are but a few of the alternatives  we offer:

Build it yourself!- Here at HRD  we are happy to be able to provide a large range of engine parts for you to rebuild your ailing engine with. We offer pistons, rods, and other internal engine parts  from all the top brands such as  Arias,  Pauter, CP, JE, Scat, Eagle, HKS,  etc. These can be found in our ONLINE STORE and technical advise is available via email or phone at 720-212-5838.

ENGINE PACKAGE  WARRANTY!!!

Yes, thats right  we warranty our performance engines for 1 full year from date of completion. This warranty covers ANY sort of material or workmanship defect, period. We do NOT cover damage resulting from abuse, neglect, or caused by support system malfunction, tuning errors, etc.

The warranty process is simple: If your engine fails you simply contact us immediately. If indeed the engine has failed  we  will  work  with  you  to arrange for transport back to the HRD shop. Generally,  we prefer to have the entire vehicle brought down, but this is not always practical. Upon reciept the entire teardown process will be videotaped by a third-party. This protects both HRD and your own interests and is a non-negotiable fact.You  will be provided with a copy of the video on DVD Immediately following the teardown. If the teardown shows  ANY sign of assembly error or part defect we will rebuild the engine to the original spec and ship the engine back out without delay. Now, the OBVIOUS qeustion is, what happens if the failure isnt conclusive in showing that HRD is at fault, or the end-user is at fault?  Will you just get screwed? NO- definitively NO!  We will  ALWAYS lean to your favor should the exact cause of the failure not be clear. In most cases this means we will perform the rebuild for free. Even should  we determine the failure was caused by abuse, neglect, etc, we will typically provide the rebuild at a reduced labor and parts costs.

NO OTHER ENGINE SHOP HAS  A WARRANTY LIKE THIS!  And as far as I am aware, very few engine builders videotape the engine autopsy via a third-party and have a copy delivered to the customer. Here at HRD we all take great pride in our work, but things can happen, mistakes can be made and when those things happen we stand behind our work 100%.  Even if it is not our fault we appreciatte our customers and the choice they made to use our services and  will do what we can to help in those situations.
