Comer K80 and S80 Engineering By Tornado Engineers

High frequency shaking, cryo treatment to below 300 that goes up and down 1 degree a minute for three days, line boring, friction reduction, stabilization during break in.... why do we do all these things and more? Because it is what it takes to make a stock C50 engine better. But these are K80's why do all that? To build the best C50's in the world we had to pile into R&D, we took that materials knowledge to the K80's world, we couldn't just leave it all behind. The other answer is because you want to go faster, you want to push it harder and run leaner longer. You want to win.

We are not like the other builders that blueprint the next motor and ship it out. We push the envelop after we find a good piece to start with. In the end all that work pays off because most of the time in the big races the top 5 are only .07 seconds apart. If we can hold the cylinder straighter a bit longer at high temps then your driver can pass at the end of the straight after a long 18 lap race.

We believe that what our customers want is not the cheapest engine but a really good one built by an engineer that cares about the finer details inside the engine. You aren't looking for a machinist that punches out engines all day, you want someone that sorts through these and knows what to look for. Comer is making the K80's better now after a bit of unequal production runs. Now is a good time to upgrade to more horsepower.

The methods used are legal for IKF, Stars, WKA and most other groups. It is a combination of several small details and searching for the motors with the best potential. No two motors are the same. Two motors can be only ten serial numbers apart yet .6 horsepower different. The technology to test our C50 engines has helped the K80 program immensely.

The dyno we utilize is a 5 inch water brake dynamometer for 2 cycle kart engines and helps us see inside the K80 as the rings seat and the engine develops peek horsepower. We've been know as the worlds premier Comer C50 builder and now we have taken that commitment to the K80 program and other engine packages. With over 400 hours of testing and dyno time slated for 2008 alone. If you have a K80 and want to see us make it faster then send it up. If you're a top runner and want to test our K80 against your current engine builder we'll arrange a test. Just contact the Chief Engineer at (916)390-6474.

We supply K80 and S80 engines to countries all over the world including Australia and Venezuela. Our Venezuelan Kid Kart national champion moved up and was soon the fastest on the track with our K80 package and pipe. With our dyno we can tune to any kart rule book specifications and give you the edge you need to win. K80 racing in the US is very competitive with over 35 participants in many California races. Get your engine from the most competitive area of the world and watch just how fast it is compared to what you are running today.

Our K80 motors are highly machined to rules stated in the various technical inspection rulebooks. They are an investment because they are hard to find and time consuming to test, but because they are gifted and set up correctly you are passing people on the track legally. There is much satisfaction in a win where you pass everyone and get checked thoroughly in tech. When you are declared the winner in tech and everyone walks away scratching their heads that's very satisfying because you and your driver did it within the rules.

Special Notes:

K80 Tests

A new client brought in a few K80's built by a top builder in the West. People believe that they are the best builder of K80's right now. We had three of our own engines to compare with the two. Each of our three levels were better than the other builders K80 on the dyno. While one had a peek HP that was .1hp in the 11000 band it was a momentary peek. Our engines had a much flatter curve and held the power advantage from 7,000 rpm to 12,500 rpm across the board. While this is not a systematic test of all engines in the marketplace it is confirmation that we build some of the best K80's on the market today. Some builders sell off their lesser engines to people in other markets, we just retire these engines or sell them as practice engines. Our best engines are just that, the best heads and parts, proven on the dyno.

 * The K80 Falcon 

This is our entry level race motor. Great for club racing and even some regional races. Built from a fresh K80 and to the specifications in the IKF, Stars and WKA rulebooks. These engines are great for getting started and many are capable of winning bigger races. They are not selected just built from a new engine out of the box. The next two engines are selected for characteristics of the heads and performance on the dyno.

* The K80 Hornet

If you have been stung one to many times by the competition and would like to fly to the front of the pack the Hornet may be your engine. This engine could be a used engine or a new one.  The motor is taken apart and checked, then rebuilt with the best existing parts and configured to exacting specifications. Then checked on the dyno and broken in for easy introduction into the practice schedule.

* The Stealth

This engine will sneak up on the competition and drive by before they knew what hit them. These motors are hard to find select head castings that simply perform superior to other motors. Hand selected and carefully reconfigured to perform at the top of the regional races and national events.

* The K80 Super Stealth

This is the engine with all the treatments we can add legally, the attention to detail on each part and a selective head, case, flywheel, carb process that yields a much superior race engine. Gifted to begin with the ports are shaped the way we want them, the carb is built with the latest modifications for a nice carry through on throttle response. Advanced tuning is done on the finest low hp engine dyno in the business. We simply keep taking the engine back to the dyno until it is finely tuned for each part and has maximum torque and hp. Give us your chassis info, your home track specs and driver specs and we'll build you a super engine that will surprise your competitors.

Some people have asked for a guarantee that they will pass tech. This is impossible to do for several reasons. First we can't guarantee that someone else doesn't modify the engine after it leaves here. We once had a customer take one of our engines and lap other engines we produced. That same customer was later DQ'd for head work. It is hard to see how one of our engines could lap other engines we produced. The other reason is that parts break and can cause a DQ. Tech directors can also make mistakes.

The best thing to do is to ask for your engine or component to be held in tech if you receive a DQ. Ask for it to be sent up the ladder of IKF or WKA. Often local tech directors can read a discoloration in a port as port work when they just haven't seen enough of them to know. To our knowledge we have only had two engines DQ'd in four years. The first was one my son was racing. It was over a missing component in the air filter. We proved that certain older engines never had that piece installed in the following weeks and the the DQ was in error. The other is the one we mentioned earlier. There are very few things as painful as receiving a DQ in a big race. We do everything on our end to make sure it doesn't happen. In the end it will always be your responsibility to assure that your engine passes tech. The best way to do this is to ask a tech director to look at your engine prior to a race - most are willing to do this happily and they are not very busy before racing begins.

We accept credit cards through our paypal.com account. Just log into www.paypal.com and select mail@tornadodriver.com as the person to pay and we'll get started.

Call us at (916)390-6474 with any questions. We have a few motors ready in advance some times but many times you'll need to order and give us a few weeks to get everything ready, tested and shipped. Shipping and handling are $20 plus $8 for insurance. Overnight shipping is usually $90 via UPS and $58 via US Mail (not guaranteed).

Race engines do not have warranties. We test and run each engine before it ships. Once it leaves our facility it is your engine and can't be returned for a refund. Well meaning people can and do forget to put oil in gas, drop engines or run them with the wrong plugs. Even if the engine has a problem after the first day it can't be returned because there is no guarantee or warranty on race engines. No engine can be guaranteed to pass tech, because they can break, be modified once they leave our shop or be read incorrectly by a tech director. This is standard in the industry. We know they are in good shape when they leave here because they are tested. The engines can take a while to find and build. We ship when they are done - once ordered you can't get a refund. Please make sure you are prepared to accept these conditions before you purchase. For many individuals this is their first motor sports performance purchase.
