People have made stand-alone turbo's spool up all the way. There are also people who add a turbo to a burn barrel (those turbo's overspool and tend to blow up). And most of the pressure/gasses already get removed from the cylinder, because the exhaust valve is floating. The pressure inside the...

Seems you didn't understand the concept. The turbo prevents the back-flow of old exhaust gasses. There IS a serious risk of having the fire go into the turbo (intake side), because there are times when there is a full open space between old gasses (unburned fuels, rich mixture), slower burning...

Being "a skeptic" is totally fine. But did you at least understood the concept? By creating intentional valve float on the exhaust port, you're pushing more hot more expanding and more energy straight into the turbo. And leave just enough pressure, to keep the piston moving up and down. (hence...

Managed to get a near-full parts list for the project I had in mind. It will likely cost me about 400 euro's, and that's excluding unforseen issues. So I won't be building this project. What the project plans were: I had planned to put a "RHB31/VZ21" turbo onto a 3hp 127cc briggs and stratton...

Been looking at the parts lists and getting a price for the entire project. Going to cost about 400 euro's, which I'm not willing to pay for a laughs and giggles project. Will post in my intro page what my plans were. This thread can be locked.

Exactly. ;)

Secret sauce. It's going to be more then plenty. ;) I was aware of your concerns, but they don't apply.

I had planned on adding an alternator as a dummy load. But those are all minor details. I created this thread to find a component which I'm struggling with. I'll be placing the carb infront of the turbo. I'll be going to overrev the engine by a small margin. (4200 rpm) Over reving and feeding...

I've done much research on this particular issue, and I found a way to bypass that issue you've mentioned. And I didn't encounter anyone else who had the same plans. If I end up not building this turbo project for whatever reason, I'll give the "secret" away.

I had to mount the engine this way for multiple reasons. It already didn't fit. But pre-turbo plans, this was my only option to make the tank/carb fit the frame. And to keep costs down, it made sense to ME, to go with a friction drive. That "drive train" in it's current setup was made from scrap...

My "party trick turbo setup" requires a flathead. Other engines would self-destruct.

It's an abandoned unfinished project at this point. I had planned on using rods to push/lock and pull on a rod to lock the friction drive roller onto the rear wheel. Should add loads of force you don't see on more normal setups. Maybe weld a bit around the roller, so it gets loads of spatter...

Video attempt.

I'm sure I had added a YT link, but I'm guessing it got auto-removed because I'm new to these boards. I'm sure it'll be going FORWARD. The engine is facing the CORRECT way, so I might get some kind of ram scoop going on. You might want to look again at the pictures. It's a friction drive. The...

Exactly @ shipping costs @landuse . It needs to remain a for-fun project, without breaking the bank. And when shipping costs are 2x the price of the actual part, that's not ok. (this turbo project is going to cost me way too much moneys as-is already...) Do you know what part number I should be...

Yesn't. Gotta find the correct server which isn't dead, that contains the people with the correct knowledge. And that can be slightly hard at times. I also used AI, but I found that it isn't reliable at all. Especially when I ask it to provide actual store links for parts. That just does NOT work.

I didn't even know Discord had a picture gallery. Might eventually one day maybe look into that. And hmmmz... Maybe some people will drool over my Mercedes OM636 engine. :P

I came here for some specific small engine questions. That particular engine isn't even mounted to a gokarts, although it does at least fit the theme. All my other projects are kinda totally unrelated. ;) Already posted a question about that small engine, before I created this intro.

Hi all, I'm an older poor crazy person from the Netherlands. Have watched loads of "cars and camera's" vids on Youtube. I enjoy crazy ideas and concepts. Got a bunch of lawnmower engines (all B&S after I threw some away/lack of space), and I've also hoarded a few small 2-smoke outboard engines...

Oh, the engine is currently mounted to an unfinished/kinda abandoned motorised bicycle project. Lost motivation, got some different projects. And this turbo might make me interested again. Frame has been notched to fit the engine, and reinforced again. Replaced both the front and rear hubs/kept...
