Re: M500 build log

How's the build going? I'm curious on how you are going to design your fuel system. Fueling was always an issue with my big lockwoods.

Re: My father

Joost, I'm so sorry to hear about your father. I understand what your going through. I lost my wife suddenly back in April. I know everyone tells you it will get better with time and right now it's hard to believe that. You never really get over it but you learn to live with it. It does get easier w...

Re: help us please

I've got drawings of the way I did mine. I don't know how to post the link but if you search big lockwood pulse jet or my name I think you can find it. Also I've got some videos on youtube. One of them is a walk around showing how I did everything. If go on youtube search my user name geardaddyart a...

Re: big lockwood style plans see if you think it will work

Keith, I just read this thread and watched your vids this morning. That is some beast you got there! What are your latest developments on this project? I've been thinking about gas injection for my second build. Hey thanks. I've had to put off the project indefinitely. My wife passed away April 29 ...

Re: big lockwood style plans see if you think it will work

Yep thats the stuff! Good work. Is that straight up liquid gasoline? If you haven't already tried it, might mix about 10% methanol with the gasoline. Typically found under the brand HEET. A big jump in performance will probably be observed with an intake augmentor. Amazing its producing that much t...

Re: big lockwood style plans see if you think it will work

I've got finally got the redesigned pulse jet running! I was able to get it to running just on gasoline. The thrust is not there yet but I think this design is good. Just need to work on the fuel nozzles. Here is a video of the "new" engine. First part of the video shows a very close call with the e...

Re: big lockwood style plans see if you think it will work

I might not be able to do it but it give me something to work towards. If nothing else I'll probably have the only pulse jet powered go kart in the state of Tennessee! :D

Re: big lockwood style plans see if you think it will work

The plan is to put two of them on a kart racing frame. My goal is to push a kart 70 to 80 mph in a 1/8 mile. Kind of like Bruce Simpson's dragster. I think he said he was getting 160 lbs of thrust per engine. That's the future plans. It will be awhile before I even get the kart frame. Got to get the...

Re: big lockwood style plans see if you think it will work

Looks like the expansion in the tail could be shifted forward about three calibers. That somewhat shifts it from a beginners tail to a more advanced design. I usually come to the same conclusion when using the smaller diameters in the tail, it tends to feel to small and the pressure tends to "dump"...

Re: big lockwood style plans see if you think it will work

I'm having problems with the engine flaming out at higher power settings and I'm only getting about 20 to 30 lbs of thrust. I'm thinking my exhaust is too small. Here is a draw of a redesigned exhaust. You guys take a look at it , if you don't ming, and tell me what you think. Thanks again for every...

Re: 3 inlets

Very cool! Think you could scale one up to make 100 or 200# thrust?

Re: Idea for Adjustable Fuel Injector

That looks like a pretty cool idea. I might have to try it out on the big lockwood. Any ideas on how many holes you think to run a big lockwood?

Re: big lockwood style plans see if you think it will work

Not yet. I've been busy with work. Hoping maybe next week I can work on it some. I was kind of hoping to that some one here would have some idea of what might be wrong. I'll post more video when I start testing again.

that's when I got the 20 to 30# of thrust. Maybe my nozzle are in the wrong place or my intake is too small I don't know.
