    Hypothetical Build Questions. Motor Related

    I have always had a thing for land speed racing and its on my bucket list of things to do.
    But as like all of us the gears started turing in my head about what motor to use if i was to ever do it. Things like fitment in a class come to mind but mostly I was thinking about keeping the cost down and making it "easy" on myself.
    LOVE the buddfab streamliner! I just like the idea of a streamliner from the engineering and challenge point of view rather then a XXXX bike converted to run.

    So if you guys were going to build a small streamliner what power would you use and why?

    Would you go with a simple small two stroke dirt bike engine or cbr1000rr engine?

    500cc blown mill. classes for that engine are almost open. sure it is setting the bar low but hey if you can do it go for it. you could triple threat it - mps and then streamliner using something like a blown ex500.

    First of all i wouldn't build a streamliner. You want to keep costs down and make it easy on yourself. That sentence and streamliner don't fit in the same sentence. The requirements for a streamliner are a lot. Full cage, sealed compartments, harness, fire suit, fire system, HANS, etc. You could build a couple of bikes for what the rider safety gear would cost. They are basically money buckets. The days of Burt Munro and a full streamlined shell around a sit on bike are long gone.

    Why not think about the partial streamlining class? The rules have been relaxed so much over the past couple of years they aren't far away from full streamliners. Or better still. A sidecar. The SCTA rules on them is very short and the only rule they get excited about is the "unrestricted entry and exit" rule. After that you are pretty much free to do what you want (within the rules of course).

    As to engines that would be up to you. A CBR 1000 in a streamliner would put you in the same class as Burt Munro who is the current record holder. For some peculiar reason that record is cursed or something. A number of people have tried to break it and have failed. usually to crashes. And thats not a joke. Ask Kent Riches of AirTech.

    Personally I would go with a smaller engine for openers. If you have to build a 'liner build one with room for variation. The McLeish Bros. built a 'liner sidecar some years ago. They had planned to run various engines from 50cc to 1000cc. They hold records in a lot of classes right up to 1000cc (218+ mph)

    I know it will probably stay on your bucket list as a lot of things do. Building a 'liner takes a major commitment not to mention a pile of cash. But if you are determined to go land speed racing start with something simple. If you find its your cup of tea, progress from there. It can be rewarding to know you have broken or set a world record. The SCTA clocks are as good as they get and their procedure for ensuring accuracy is beyond reproach.

    As you probably know I've been doing the land speed thing for about 15 years now. I'm old and should be rockin' on the porch but it is so much fun to go to Bonneville and hang the throttle open for three miles and see if you put the engine together right. I don't go very fast but seeing how fast you can make what you got go is the main point. At each event you get a brass timing tag. It shows your top speed for the event. I save mine as soon all this will be a memory. Black ones are for participation (you didn't break a record). Red ones are when you break a record. You can see by the board how long it took me to get a red one. You got to be pig headed (or so stupid you don't know when to quit). Its not an easy row to hoe. Good luck with the idea. I hope it comes to fruition.

    A P.S. to the above. The ECTA lost Maxton as is pretty much known. They found a new venue in Wilmington, Ohio. I just went to their site and they are limiting the entry to 175 which they have reached. If you are anywhere near there it would be worth taking a look. You'll get an idea as to how things work.

    I agree that a 'liner isnt the most cost effective way of doing things but really liked the idea of one with a modular type engine section to run a bunch of different engines

    After seeing what guys have been doing with small motors i cant see the need for a million liter monster.

    Guess i didnt really understand that the 1000cc NA class was the same as "the fastest indian" must be cursed if its been this long with no one beating it.

    Mostly my mind goes to liners for the freedom to build to a purpose.
    Didnt know they lost maxon, heard about the racing up in lorins and would like to check it out.

    Whats the blue tag?

    It's for breaking the sound barrier. I heard the sonic boom here in O.C., hundreds of miles away. Hoof is wanted in three states for all the windows he busted on that run.

    Should have said. The blue one is a World Finals at Bonneville. No record. Just a frustrating few days. I've never run BUB so I don't know what their rules for 'liners are but the SCTA has certain criteria you must build to. Its not a case, as has been said before "its my life I'll take the chance". Its the SCTA's ball and field so you play to their rules.

    Go to scta-bni.org and have a look around. You can check out Bonneville records and see what you like. And see what speeds you would be up against. But if a 'liner is what you gotta have, good luck. Hope your bank account is more than healthy. Or better still you have a serious sponsor. It ain't going to be cheap.

    yeah i do understand what you mean about building to a criteria and it being money....but a kid can dream....
    Mostly was thinking that as i was involved in building two FSAE cars and starting on a baja but those rules are alot different..

    Honestly I would LOVE to join the 200mph club but as with everything its easier said then done.

    What do you run and what drew you to it?

    Would one be better off with a small displacement single or is it all racing and all expensive.
    not talking about a shoe string budget but something thats achievable on a personal finance level
