We spoke with HPi via Instagram to get the rundown on the project.

Machine details

Horsepower Inc. used a DNM 400 HS and a DMV 4020 for this part. The DNM sports a 31ia5 control and 14,000 r/min spindle, plus a 30-tool ATC and KOMO TN-161. The DMV has a 21i control and 12,000 r/min spindle, as well as a KOMO (Tsudakoma) TN-200. Both machines are equipped with Renishaw tool/part probes and Lang fixtures.

Part details

The throttle body is made from billet 6061 aluminum, and it takes two operations to complete. The intake is a 356 aluminum sand casting. The intake also takes two operations to complete.

When asked why the Doosan machines got this work, HPi replied, “We have been using Doosan from the start of the company, back when they were still Daewoo. We have great support from our reseller, Allegheny Machine Tools. We currently have 11 machines of various ages and models working tirelessly to produce our high quality parts.”

Company details

Horsepower Inc. is a leader in v-twin fuel injection, serving over 30 dealers in the United States and around the world.

They stay OEM-compatible throughout, which keeps their product affordable for customers.
