Welcome to Haibeck Automotive Technology
The ZR-1 Specialist
This is our 415 ci engine, owned by Lodell Parks. It develops 673 crankshaft hp normally aspirated and 801 hp with the nitrous oxide boost. I don't recommend nitrous boosting. We built this engine because that's what Lodell wanted.
On the dyno chart, run .002 is normally aspirated. Run .004 begins with full throttle at 2500 rpm, then the window switch triggers the nitrous at 3000 rpm. The progressive nitrous controller runs 50% nitrous for about 1.5 seconds and then opens to 100% at 4500 rpm.

Joe had the fastest normally aspirated car at the event. On the SORC www site the one mile race is called the, "Shootout". www.sorcrace.com
