What makes your engines better?
We specialize in giving a customer a winning combination at an affordable price. The Initial cost of the engine and the maintenance costs are lower for our engines because everything is correct from the start. Our blocks allow us to build bigger, faster, stronger, more reliable and less expensive engines. As far as performance goes, track records have fallen everywhere our engines have run. A heavy car/driver package can now hit the 7.90 performance level, even at higher altitudes or with a muffler.

Why is there such a price variation between engines advertised that appear to have similar specs?
In all forms of motor sports, you have a few skilled engine builders and a lot of "engine assemblers", who just bolt together a bunch of parts and hope for the best. Engine building requires an enormous amount of R&D, uncompromising quality standards when selecting parts, an exceptional understanding of how all the parts in an engine work together, and meticulous attention to clearances during engine assembly. As you can see on our Winners page, our engines are routinely found in the winner's circle. If you ask any of our customers, they will tell you that our engines are famous for reliable and consistent winning performance. The real cost of an engine is the "cost per win". A bargain engine that doesn't get your driver in the winner's circle isn't really a bargain. On the other hand, when you are ready to move up to a faster class, an engine that has won races will command a much higher price when you sell it.

Will today's clutches stand up to your more powerful engines?
We offer blueprinted clutches to match our engines, using the finest parts in the industry. The most successful teams rely on our experience and knowledge to assemble a proven package of components necessary for a consistent, race-winning engine combination. Because of our Top Fuel experience, we were the first to use on-board data acquisition systems in Junior Drag Racing. With superior data and experience, we were able to engineer the correct components to work with our engines.

Is there anything new in camshaft design?
Of course! A whole family of new cams has been created to maintain our horsepower per cubic inch ratio with today's larger engine displacements. New materials and heat-treating are being used to ensure the structural integrity of the camshafts and other related hardware. Our cams for the latest moved-cam engines are the strongest in the industry and have never broken.

Are the big bore engines unreliable and expensive to maintain?
As the engines have increased in size so has the technology. Our blocks are the only ones that allow us to accept the big journal crankshafts and the large core camshafts. In addition, we use larger valve stems, bigger lifters, proper valve springs, stronger wrist pins and rods, extra header bolts, etc. A bigger engine running easily has always been more reliable than a smaller engine pushed to its limits.

What do you have for the 12.90 class?
For years there has been a mentality that all you need in the 12.90 class is a lawnmower engine on alcohol (usually unbalanced) and a stack of weight to run the number. When I entered the 12.90 class with my daughter, Kaitlyn, I soon realized that you really need the same quality parts that you would expect, and need, in the faster classes. Equipped with state-of-the-art engines, quality clutches and modern chassis, our two-car team won seven "Wally's" in the 12.90 class. The biggest reason was our small-bore, 12.90 Chris McGee racing engine. We have designed and built a true, small capacity, Jr. dragster engine. We use a Blockzilla-style block and build these engines with correct proportions, using the finest parts available. We have even built a special, small-bore carburetor using the proven 33mm-style carburetor as the foundation. These engines run at their optimum performance level and are far more consistent than the usual converted 5HP engines. Plus teams find their drivers can get good lights! When you purchase a Chris McGee 12.90 engine you have the benefit of our hands-on experience. This technology has captured the last two Division 7 Championships.

Do you have any kits for do-it-yourself builders?
We do have kits available for people that really enjoy assembling their own engines. We have found that more teams prefer to leave the engine building to professionals, because we have many times the experience assembling these engines than someone who has only done one or two. The most successful combinations we sell are complete engine and clutch packages mounted on a motor plate and ready to win.

What is the latest in carburetors?
They keep getting bigger! Today's Jr. dragster engines are far different than those of a few years ago and a world apart from engines found in motorcycles, go-karts or lawnmowers. The nuances of our sport require precise fuel mapping from idle, through burnouts, during a staging eternity, and throughout the rpm band against various clutch loadings and weather conditions. Based on a lifetime of racing experience, we have developed proprietary carburetor modifications that ensure each carburetor performs at its peak in all these conditions. We can also provide unique solutions for customers who have special applications. Of course we provide support for our carburetors, both over the phone and at major races.

How often should I have my engine refreshed?
We recommend returning 12.90 and 8.90 engines every 200 runs to be freshened. Due to the higher demands on the 7.90 engines, we recommend returning them every 100-120 runs. Be sure to keep good records of how many runs your engine has actually made. Chris McGee engines tend to go more rounds per race than others.

My car's too slow. Would I be better off upgrading or buying a new engine?
It usually will cost more to significantly upgrade an older engine than to just buy a new one. Upgrading an older engine usually involves a lot more labor than assembling a new engine, because we have to correct deficiencies with the old engine before assembling the improved version. With a new engine, we only have to assemble it. In addition, we have found that engines that have been upgraded are not as good as our new engines, because every part used in today's engines is better than what was available even a couple of years ago. Finally, upgrading an older engine leaves you with an older engine design. A new engine will be all-new.

How do I tune my car for different tracks?
Competing successfully at different tracks requires good information on how your car reacts to various conditions. We recommend and supply the MyChron 660 data recorder to document precisely what your combination is doing on the track. The software used to download and analyze the data is excellent and provides a means for storing all the car's setup and weather information. If you have questions about how well you engine is performing, you can email MyChron runs to me so that I can see precisely what the car is doing under actual race conditions. This makes it much easier for me to help you get the most out of your Chris McGee engine combination.
