After writing about the V-Quad engine the other day, I had the opportunity to talk with Greg Nelson. Greg’s a pretty interesting guy and after discussing the V-Quad, I think it has some potential. A few readers looked at it and were not very impressed, but Greg thought it would give the custom builders something a little different to play with not to mention it would be a nice engine in the right motorcycle powered car, like maybe the HotRodHawg. I have to agree.
I asked Greg about cooling, which was my first concern and he said he’s been running one in the FXRS shown here with no trouble at all, the power the engine produces means you need very little throttle to get moving and keep moving. Unless you’re really hard on the throttle continuously, generating a lot of heat, cooling isn’t an issue.
The pictures here of his prototype also show how unobtrusive the engine is. What I find striking is that with a quick glance you might miss the extra two cylinders which is kinda neat. Some builders might draw attention to the extra cylinders, which would be understandable, but if they wanted to be subtle about it, they could do that, too. The FXRS prototype was recently sold and he’s thinking the next bike to get the V-Quad should be a bagger. A 200 horsepower 4 cylinder bagger, I like that!
He also said the engine fires big bang style, the cylinders fire together on both engines so it sounds just like a regular Harley. Although a twin turbo version has already been built, one customer has a supercharged version in the works.
Greg also has plans for a Bonneville run. They are planning on running in both AP-G and AP-F (gas and fuel) classes to see what they can do. That should answer questions about any durability issues under load.
The engines use relatively few unique parts to join the two, though there is a lot of experience and knowledge in the engineering of those parts. Each engine is run on a test stand and video of the run is included with your purchase so everyone knows it was running before it was shipped. They are $21k in an unpolished form, figure an extra couple of thousand for complete polishing. If you figure the cost of 2 engines alone, that’s not a bad deal.
No, this engine isn’t designed for a sporty canyon carver but it doesn’t take a lot of thinking to come up with some interesting placement ideas. I like it and I also like the idea of someone who decides to make something like this and actually goes out to his shop and does it. The added benefit is you can buy one, too. Nice work, Greg.
