The ExTech "II" .24 engine will give Truggy Racers that extra power they desire, that a .21 size engines can't offer. In the past the .28 size engines were the only option to get this extra power. And with fuel efficiency being a big part of the pit strategy at today's events the .28 size engines are rarely seen at full competition racing. That's were the ExTech "II" .24 engine stands out. Not only is the power equal to some .28 engines, but the ExTech "II" .24 will get the run time of a typical Race .21 size engine.
It's the design of the Extech "II" .24 that makes this engine the power house that it is. The square Bore and Stroke (17.17mm) and Long Rod (29.997mm) design gives the engine a better balance, which increases power and efficiency throughout the power curve. Not only does the .24 have the bottom-end power of a typical Race .28, but has the upper rpm power to keep pulling you down the longest straight you may encounter.
Until now most .28's or .25's size engines have used the .21 size engine stroke with a punched out bore. And typically use the short rod (29.48mm) of the 21 engine. That's not the case on the ExTech "II" .24 Truggy Engine. The Bore / Stroke have been increased and squared to give better performance throughout the entire power curve. Offering the best power and fuel efficiency from any race engine out there!"–Ed Bridges.
