3336HP and 185psi of BOOST! WORLD RECORD!
- by Christian M
We made our way back out to the Ultimate Callout Challenge and as usual, it did NOT disappoint! Not only did the Ziegler Diesel Performance team rip off a 4 second pass (at 185psi of boost) their first pass, they made history on the dyno! We almost could not believe our eyes when we saw 3336HP after a MONSTROUS dyno pull!
