So the 2006 GTO has resurfaced as my “Car of the Day”. (COTD) The 2006 GTO received the same 6.0 liter engine from the Corvette.
With a stock 400hp and 400lb-ft of torque it is has some pretty stout performance out of the box.
However, under the twin scoops of the hood, sits a very tunable motor. The LS2 engine has a lot options to get even more horsepower out of it. The GTO is a great platform to handle more power.
One of the easiest and most cost effective ways to really “boost” the horsepower is a supercharger. There are plenty of supercharger systems designed specifically for the GTO. They are relatively low cost, around $5,000 and can add as much as 200hp to the GTO. All a supercharger really does is simply push more air into the engine. More air = more power, it is that easy.
This can be very appealing to speed freaks out there and would allow a person to keep a relative stock feeling to car without modding the engine to the edge of reliability. A supercharger with a low psi on this engine would have little to no effect on reliability.
In fact, a lot of manufacturers are supercharger their cars from the factory or including a supercharger dealer option. Companies like Mercedes-Benz, Mini, Chevy, Saturn, Toyota, Ford and Lotus just to name a few are all have or are currently offering supercharging options.
One of the problems with boosting the horsepower on cars is the reliability problems. This isn’t a problem with the GTO and one of the kits made specifically for the Pontiac. It is being done a lot out there, so watch out for any GTOs that seem to have a little extra whine. They could be sporting a 600hp boosted engine.
Reliable, powerful, and a good deal, what more could you want? This makes a GTO an even more appealing option. At 400hp the GTO is fast, at 600hp it would be a real sleeper capable of running with nearly anything.
If a GTO lands in my garage it wouldn’t stay stock for long and is a big reason the GTO is the COTD. I’d be looking for a power boost.
