    M&M racing and NCK  would like to formally announce the
    “2107 Corkscrew Spring Nationals at Mazda Raceway Laguna Seca”
    This special event will be spread over 2 days on March 25 & 26 of 2017.
    We will have access to the paddock beginning Friday evening the 25th. Paddock camping will be available for both Friday and Saturday nights. Garages will be available.
    NCK is currently working on a race schedule and class structure along with pricing for this event. NCK wishes to make this a special weekend with a number of special races and classes over the course of the weekend. As in the past this will be a 92 db sound day. We are actively seeking class and event sponsors. If you are interested please contact an NCK board member.
    Events of this magnitude don’t happen very often, make your plans now to attend what is likely to be the marquee event for western road racing in 2017.

    For more information head to the NCK Website

    Will a twin pass the db limitations ?? It would be a shame if the twins dont make it as i know at least 5 drivers that would love to race on the Laguna circuit !

    I sure would like to see some Twins again! The 250’s are getting by for the most part. You probably will need to run Air Boxes though.

    Air boxes help a great deal.

    Attention should also be paid to your exhaust exit. The sound sensor is at the exiton the right side of turn five. Point exhausts out the left side and down. Bring materials to build “widgets” for deflecting sound and plan ahead.

    I was called out on my laydown kart two years ago and adding a simple exhaust deflector at my exhaust exiting the right side pod was enough to pass. I was NOT using an airbox because it doesn’t fit in my bodywork, but I brought it just in case I had to modify things to use it. You would be wise to have airboes mounted to be certain that you’ve done due diligence ahead of time given that you’re traveling a great distance.

    We’ve had very little problem with sound at LS, but it always pays to plan ahead.

    You need to be under 92db from about 40 ft away at the exit of turn 5 just after getting back on the gas exiting the corner. The singles are making it with an airbox and the large Viper style silencer mounted across the back of the kart. According to Ian at Viper the bends are as critical as the silencer. My link pipe has a slight bend just inside the wing upright and then a 90 to go across the back of the kart.

    I did some initial testing with the 100cc Yamaha stuff at a local sprint track. I used a Radio Shack db meter. I believe and can find out for sure but it was set to fast response “a” scale. NCK also did early track testing at Sonoma and Thunderhill. Those test results have been posted to our facebook page nckroadracing.

    As we really have no twins on the west coast NCK is hoping some of the twin owners get together and do some testing in practice to see if 92db is possible. We believe that it is with the right equipment. CR125’s easily make it with a 14 to 17 inch silencer straight out the back and an airbox. With a little ingenuity a 250 twin should be able to comply. They run bike days there all the time at 90 to 92 db and the bikes find a way to make it. In our testing we shot for 90db to have a safety zone. First time we were there Laguna officials were extremely happy with our noise level. We only had one or 2 violations. One of which was a Yamaha guy who did absolutely nothing to try to quiet his kart.

    The only things that really don’t have much chance of hitting the 92db are the aircooled 100cc reed motors like a reedjet.

    We would love to see some of those blistering fast f125’s show up too.

    If anyone needs additional info or wants to discuss it further send me a message and I will try to answer your questions or point you to someone who can.

    One other idea for testing. A local sprint track with a decent straight. Try to stand about 30ft to the right. Measure at various points and see what you get. We have done that too with both 250 singles and yamahas. Our results were pretty close to actual.

  • #70319

    Laguna informed me that the meter was 50 ft from the racing line. So if you can measure from 40ft and get below 92 you should be golden. I was also informed they “sometimes” use a roving meter although in NCK’s case I do not believe they ever have.

    You MAY want to put elastomers between your cooling fins to dampen noise.

    The sound limit is mandatory.  Bring more than enough sound reduction equipment and work your way from quiet to just passing, remember you only get one sound failure, a second sound failure ends your day.  Airbox, long silencer or two, and 90 degree bends in the connecting pipe and a 90 degree bend on the output of the silencer with the output facing drivers left and down.  Experts to consult are Ian Harrison of Viper Racing, UK for Superkarts, and Art Verlinger of RLV for the rest of the karts.

      Mark,

      Are you talking 4 stroke sit ups, 206 I have had some interest in that class.

    How would you like to have a race on a temporaary sprint track in the paddock while the roadracing is happening?!

  • #71675

    We will add  L0206 classes if there is any interest. For that matter we will find a place to run for anybody who wants to attend.

    What are the TaG rules for IKF?

  • #73754

    Jim White

    I believe they are like WKA but I’ll let Roger Miller comment on that. One difference is I don’t think we penalize for using a remote starter as long as all the components are there.

    An event schedule is to be released in the next day or so listing groups and classes. There will be a WKA stock Honda class that aligns itself with Skusa rules for the 01 cyl. It will allow any listed WKA pipe. We will have classes for the Briggs animals, Lo206’s as well as the WKA controlled classes. Everyone will have the opportunity to race at least 3 times over the 2 days.

    FYI – David and I have traded some emails about TAG rules.  I think I covered what was needed.

    ALL class and rules questions – bring it on….  I will assist as needed.

    I’d like to see a TaG light class added each day to a race group to make it two TaG classes a day, and maybe entice some of the sprint racers with TaGs to race. 400lbs. is not normal weight for them, except for Masters drivers.

    With enough interest we will add classes for anybody interested in attending.

    Do all tracks have the noise testing equipment? There will ne a few of us going to Daytona. It would be a big help if we could get the reading.

    It might help if all the racers got their results listed. Just like fast lap. loudest sound.

    It would really suck to make the trip and not run.

    If you are into 125 Shifter Karts this race would be worth the price just to watch! Some really fast people are entered.

    Hi Ray, we are over 250 entries from all over the US!  Although they are not entered yet (like the 125 racers{thanks!})  I estimate 40 unlimited, IC-E, FKE-III and Unlimited entries will be coming!  Lots of groups of racers from various clubs around the country are planning together to make this the best race I have attended in the last quarter century!

    NCK would like to thank everyone who has entered already.  Please check your email that was sent to you when you entered to ensure you have:

    1.  paid for the number of days and classes each day that you want to race and

    2.  compare your entry to dlb’s web site and confirm that you got it right.

    something this important deserves a second look!

    Why is Tag heavy with 250 karts? I was thinking about coming out from Chicago. But I’m not going to race on a track with karts that can run 40 mph faster. You wont even know they are coming up on you. 40 plus entries in that class. Let them have the track to themselves for that race.
    Why not put Tag Heavy in race 6?

  • #78931

    Jim White
    Participant

    We are restricted by the track to 40 on course at any one time. Race 6 is maxxed at 40 entries.

    The tags are mixed in for just the one Saturday race. Most of our normal club race days are one day events where we have to be schedule creative. The Tags and 250’s play nice with each other on these days with no problems. Almost all of our 250’s are ICE singles, not the rippin’ twins you have back there. That makes a difference too. Nowhere near 40 mph closing speeds.

    We also offer 125/150 open classes which are a catch all 3rd and 4th entry for 100’s, 80’s, Tags, 125 shifters etc. Many Tags are registered in these classes too.
