The DeatschWerks Difference
At Deatschwerks we take a unique approach to building our high flow injectors. Other fuel injection companies offer only a couple different styles of injectors and leave fitting them up to the customer. At Deatschwerks every injector we produce is a drop-in fitment for its application. When we say drop-in fitment we mean drop-in fitment. Our injectors are engineered to fit your OEM harness, OEM fuel rail and OEM manifold (see diagram below).
All Deatschwerks high flow fuel injectors are built using only quality OEM cores. In addition, each set is balanced to within a 2% flow variation. For our customers, this means better fitment, easier tuning, and increased reliability. We back all of our products with a comprehensive 12-month warranty.
Most aftermarket injectors go straight from the production line to the shipping department. At Deatschwerks, we have added what we consider a crucial step of flow balancing and quality assurance testing on EVERY set of injectors we produce - not just one or two from each lot. Over 40 data points are collected and analyzed on each injector to be sure our customers only receive the best end product. All of our testing is performed in-house on our custom built New Age Technologies injector flow bench.
Below is a brief outline of some of DeatschWerks testing:
•6-point coil test
•Leak testing from 0-100psi
•RPM Ramp 500-10,000 rpm
•Pulse Width Ramp 0.5-17ms
•Spray pattern analysis (open and pulsed)
