About Us


Over 20 years of performance engineering experience building some of the fastest/most powerful vehicles in America. We specialize in custom engine building, machining and tuning.  We tune gas, alcohol and nitro fuels. Our machinist and lead engine builder, coupled with our facility, give us the ability to perform specialized racing engine services that are not available anywhere else in the region.

We provide all aspects of engine building and machining. We provide custom ECM tuning for many applications as well (call for details). We build NHRA legal chassis and roll cages that meet all current SFI certifications. We also offer standard automotive repair and maintenance for anyone (you don't need a performance vehicle)

Most Capable Facility In The Region

We perform all aspects of the build IN HOUSE! We design and engineer custom components right here in Wyoming. We have a complete diesel engine building program with over 100 diesel applications running strong to date. Our performance engines range from average 500 HP street cruisers to full blown 4000 + HP track applications. We proudly support top qualifiers in multiple racing fields and organization

Our identification on LS3


We build engines with the highest level of quality and take pride in our work. Each engine that has been built by us since 2008 is documented and serial numbered as shown in the example above. If we don't have it in our system then we did not build it.

Our identification on Gen III Hemi


If someone claims to have an engine built by us then it will have a serial number and be documented in our system. We rarely number parts that we machine only. Don't believe everything you hear! Call us to verify authenticity before purchase or repair of engines claimed to have been built by Wyoming Performance
