Aug 2015 - - Record setting NHRA Pro-Stock Snowmoble -- Rich Daly, Dynoport, Union Springs, NY 13160 (315) 253-9631

NHRA Pro-Stock Snowmobile speed record set 5 years ago at Maple Grove.. 160.5 MPH, "and no one has come close"..
285 BHP developed and tuned on DEPAC Dyno "with over 18,000 dyno runs on peaky 2 stroke engines".

800 XP ski-doo that Rich races up Ski-Slopes. "Massaged to 200 Hp in the DEPAC dyno room". Rich can back up runs within 1 horsepower on 250 hp engines, which are very temperature sensitive... Dynoport has the BEST Dyno System.. Proven Results!!!!

Winning the F1 UIM H2O World Championship a 3rd year in a row (also 2nd place).. LINK to Brendan Power's DEPAC/ADL tuned winning Mercury Outboards

Jan 2013 - - - F5 Motorsports, Mt. Airy, Maryland.. NHRA Pro-Stock - Another DEPAC/ADL Upgrade for a DTS PowerMark Dyno.

June 2012 - - Mike Stawicki Racing Engines, NHRA Pro-Mod

Pro-Mod Alcohol engine on geared down 10,000 RPM Brand absorber (2.407 ratio) .. Using old Clayton patented recirculating water load control. No fancy 'servo' valves used or needed here, just solenoid open/close valves.. BTW this old mechanical method works far better than any 'modern' speed control. Modern don't mean better..

The absorber starts with a fix amount of water, freely circulating between the dyno and heat exchanger. Note the classic 'Square Law' torque rise with RPM, until you are a full throttle (where this curve intersects the engine's torque curve). Most all water brakes have this type torque curve. The amount of water to start is set by trial and error. The sweep Up load is set by having a solenoid valve release water from this Closed water flow loop. A restrictor outlet valve sets the rate of Load drop (rate of water loss) and the engine follows its natural acceleration ability (unlike the erratic 'monkey motion' caused by so called modern speed controls).
Full Up-Sweep shown here while water is being released from the closed water loop.

New ADL Control Installation on one Stuska® 800 Dyno at Ernie Elliott's Concord, NC engine shop. One day temporary setup using wire and cable ties to locate tank, lines, power module, and Control Panel. Next to do is a Perminent installation. This engine just completed a Nextel Cup race and is 'broke-in'. PIC at the back

Six Pulls to 'simulate' 3 laps arround a short track to combine into accurate average performance curves. Emergency Stop at 9700 RPM when done for a clean cut and plug check. The ADL is set for a 9700 RPM Rev Limit. See Hi-Res 11 Meg

Using the Break-In Mode to cycle the engine from 6500 to 9000 RPM (for Cam and valve train) followed by a 'demo' Emergency Stop. See Hi-Res 4 Meg

The last 3 of the 6 'simulation' Pulls are Combined and curves compared with a no-change 'simulation' 30 minutes latter. The average Power is the same. Observe the very subtle details in the curves caused by the complex crossover exhaust system. The DEPAC System does Not Filter data and does Not Smooth curves so results are True and Honest. DEPAC is only for those few who know the difference.
