Dorch Engineering B58 Gen1 DE70 Injectors

After years of development, Dorch Engineering is excited to introduce the world’s first true upgraded DI injector! Until now, the only way to achieve increased flow in the aftermarket was to modify an OEM injector. This of course is ultimately a compromised solution and as their legacy can attest to, at Dorch Engineering, we simply don’t compromise. Instead, through their long-term engineering partnership with Stanadyne, they now have a proper B58 injector solution, designed from the ground up. By leveraging Dorch’s hardware and software applications expertise with Stanadyne’s patented technology and manufacturing capabilities, they end up with a Tier 1 OEM quality drop-in injector with MASSIVE fueling gains!

Since they're working with a blank-slate design, what you get is an injector that has truly been optimized for the aftermarket performance world and for alcohol-based fuels. At the most basic level, we’re able to simply make material choices that ensure the best possible E85 compatibility and reliability. In a deeper dive, a more efficient magnetic design allows for the best possible ballistic control. This improved low pulse-width control in combination with having COMPLETE control over our spray pattern, is the real secret to the success of these game-changing injectors. Translation: We can increase flow by over 100% without sacrificing idle quality on pump gas!

DE70 Injectors

	OEM	Dorch DE70
Gasoline Flow Capacity	675whp	1050whp
E50 Flow Capacity	600whp	900whp
E85 Flow Capacity	520whp	800whp
Flowrate (200 bar)	900cc	1550cc

*tuning plays a big role in the power potential of a DI system. The numbers above are quite conservative based on average results.

The initial release for Gen1 is the “smaller” DE70 injector which offers +70% additional flow beyond the stock injectors. These are true 70% gains while retaining stock drivability and idle, and they're just getting started! Making an injector flow a ton of fuel is the easy part. It’s that flow combined with the stock pump gas idle characteristics that sets Dorch well apart from any other option.

Software changes are required to run these injectors. If using Bootmod3, MHD, or MG Flasher, simply check the box (COMING SOON) for our injector upgrade when flashing. Otherwise, please send your .BIN file to tuning@dorchengineering.com for the appropriate software implementation via WinOLS.
