Todd Goodwin and the crew up at Goodwin Competition engines are on the bleeding edge of horsepower making technology. One of their mills powered the “See Red” to Drag Week victory in 2015 and their prowess in the realms of marine applications and pulling are the stuff of legend. They didn’t get their reputation by simply bolting other people’s parts together. Nope, they make their stuff, like virtually all of it in house. The attention to detail and testing they do is just a part of why they are a success but it is a big part. Take this video for example. It is a pretty gnarly watch because of what’s going on.

For starters you will hear a voice (Todd’s we believe) informing us that this is a 6,000-7,500rpm test to check for timing belt whip. There’s a camera fixed right on the belt. The engine is not running. Instead it is connected to a Spintron machine that is going to turn that baby over. We do not know what the displacement of this engine is but we’re thinking it could be one of the big 670-odd cubic inches that are the mainstay of Goodwin’s marine program. If so, that’ll give you an idea to the brute strength of a Spintron machine.

The nose of the engine simply rotating is spectacular and Goodwin calls out the various RPM levels as the engine climbs higher and higher. This is not some immediate blast up to 7,500 and then shut down. No, this takes a while and that gives you plenty of time to watch, listen, and create deep as he creeps the RPMs up a like a hundred at a time from 6,000 to 7,500. It is singing a GOOD song when it gets to and sits at the top of the rev range and that is simply the noise of the air being pumped through the engine and the valve train working.

Great engine assembly is something that every machine shop strives for and it is very important to keeping customers happy. Great engine building goes miles beyond that with testing, development, and problem solving like you will in this video. THIS Is freaking awesome.
