We remember when the crew at Noonan Race Engineering came to PRI a few years ago and displayed this incredible all-billet LS engine that was wearing a massive screw supercharger. It was a show stopper, literally. The swarm of people around the thing was impenetrable all weekend long and there was good reason. It looked incredible. The billet jewelry look of the engine, the fact that the screw supercharger was the size of the long block, and the idea that someone had basically taken the idea of an LS engine to the most extreme degree had everyone excited.
It struck us that we hadn’t remembered seeing the engine run or make power and so we scoured the internet for about 13 seconds and boom…there it is. Video of the engine making a rip on the dyno, producing more than 2,100hp at 7,000 rpm and doing it very conservatively as this was before the whole works went to PRI. So what’s the deal?
462ci, 4.200″ throw crank, 4.185″ bore, 35 psi of boost, and 20-degrees of timing. Outside of the bore and stroke which is what Noonan recommends as max for boosted builds, the rest of it is easy peasy stuff. That level of boost and timing is not even working this thing close to the maximum and so one has to wonder, is the potential for 2800-3000hp there? We’d sure say that it is.
We’re not 100% sure anyone has stuffed one of these in a race car yet and run it hard and fast but it is only a matter of time. The compact nature of the engine, the weight of the thing, and the potential for making power will attract the right people who want to push the program forward. Until then, enjoy this!
