Precision Research & Development Services
Contact Customer Service for immediate assistance on R&D related questions.
R&D is a passion at Arrington Engines. Our emphasis is on creating and building power and reliability into racing motors. We do it for Dodge Motorsports as well as NASCAR and NHRA race teams. Our specialty is the American V8 engine, including GM and Ford, with a particular focus on Chrysler/Dodge HEMIs, both late model and legend. Some of the areas you might look to Arrington for research assistance include:
Fluid Dynamics
We have a special skill set in fluid dynamics, specifically, measuring and adjusting the movement of the air fuel mixture in and out of the combustion chamber with extreme high efficiency. Our specialties in this area include:
Valve Train Design - We can test valve train components all the way to destruction. We conduct this testing on our spintron, collecting data in the process. The data identifies the point of failure, which gives us the information needed to redesign the part.
Harmonics Elimination - We measure harmonics on the spintron by cutting open one of the cylinders and shining a laser against a mirror placed into the cylinder which reflects light up to the valves which are going up and down to a rhythm. Imagine the following beat (clapping with your hands) clap-clap---clap-clap-clap. The laser identifies an inconsistency in the beat or clap – which gives you clues as to where to look for the problem.
Flow Bench Testing - We have several flow benches. One of our flow benches has a fixture with a proprietary design that gives us the unique ability to target the precise location that the air fuel mixture will impact the piston. It measures the amount of tumble and swirl as the air fuel mixture enters the intake manifold, and the point at which it hits the piston. (The goal is to hit dead center.) We believe we do this work better than any engineering shop in the business, including the major automakers.
Parasitic Loss (Engine Friction)We’re very good at finding ways to reduce parasitic power loss in the engine. The idea is that once you achieve very high volumetric efficiency the only place you can go to “make power” is to eliminate places where you lose power, essentially that means reducing friction. We can define where losses are occurring in the drive train and identify methods for eliminating.
Digital Part Prototyping and ReplicationWe have the capability of digitizing any part, on one of our 3 digitizing machines. If a customer has a unique custom part, even one he has built by hand, we can replicate it precisely. The deliverable on this work can be: a paper drawing; a CAD drawing; a 3D Model, or an actual part. You can see some of the parts we have created on this web site by clicking on these links: ChipKillr & The 90mm Throttle Body
Custom CAM shaft developmentDo you want to make power from 6800 to the redline; or would you rather your power comes on at 4500 and peaks at 6800. Either way we can do it. We can put max power in the engine wherever it is that you want it, largely due to our knowledge and skills at CAM development and design.
Real-time Performance Data AcquisitionWe hook up and measure engine telemetry on the track at the NASCAR level.
Distributor DynamometryWe have an unusual, almost arcane, piece of equipment, a distributor dynamometer. Few street machine enthusiasts will ever need this, but it is an absolute necessity for NASCAR work.

Engine Dynamometry 
We have one of the very few engine dyno cells that can run a new HEMI motor on a stock engine control unit.
Chassis DynamometryWe can run a full car in our chassis chamber, with simulated racetrack load conditions and controlled-atmosphere conditions year round. Our custom made SuperFlow edy-current equipment has 116 instrument channels for measuring power, torque, speeds, incorporate pressures, temperatures, analog and digital inputs. We can measure normal and acceleration speeds as well as coast run to determine drive line loss during deceleration.We have one of the very few engine dyno cells that can run a new HEMI motor on a stock engine control unit.
