EcoTron EFI & Turbo Kits
 

Anybody brave enough to try either the EFI or Turbo Kit.

These guys seem pretty organized.

Can't say I'm not interested. :yumyum:

What would be the performance difference between EFI and carb?

Efficiency and fuel mapping. EFI, to me is easier to manage, but the simplicity of a carb out weighs almost any small engine EFI. If I am not mistaken, the EFI was designed to work in conjunction with the turbo kit, which would aid in mapping the correct fuel curve through the entire RPM range. Also, with EFI, you don't have to buy new jets for every engine mod, if you have a decent range injector. All you would need to do is plug your pc into the control module, and adjust the duration(how long the injector is open) and be done.

Masteryota pretty much said it all. There is power to be gained using an efi kit in cunjuction with all the other mods. Best thing about it is ability to change the fuel mapping. Depending on the type of riding you do, you can set the mapping to suit.

Like I said, to me it is easier to understand and manage the EFI system. I am fluent in all the popular management types, and see no other real way to run an engine for proper efficiency and longevity of internals, but a properly jetted carb is so much simpler, and in most cases, the carb will respond faster in highly modded engines. I have also done some research into the small engine turbo kits, and with the proper size, the carb can also be used in conjunction with the turbo.

I had thought about a similar turbo for my yerf/honda build, but I think a bigger engine would be a better investment on my side. There also has been at least one buggy user that tried a turbo, but the 150 did not produce enough exhaust to spool the turbine to its full potential. If memory serves correctly, he was only able to get around 5 psi of boost.

Agreed. I don't think these little engines could sustain a turbo and be reliable. As a hobby, I would think putting an EFI in would be a great way to tinker further with these little power plants. I'm still on the fence. The price to enjoyment ratio is a bit off for my liking.

In reality, the only thing you would really need is a forged piston to handle the boost, but I doubt you will see enough boost to offset the initial investment. Not to mention the weight and plumbing needed for oil lines, oil coolers, intake tubes, exhaust pipe, and so on. The kit I was looking into was ~$300, but add in all the other stuff, it would likely set you back close to $500. I can pick up a lager quad engine, or street bike engine for about the same, and have reliable power that requires minimal maint and tinkering.

The turbo's will work on the GY6. How much more power I cannot say. I do know however the injection was designed to be used with the turbo. The GY6 will handle a turbo, but with any tubo engine you want to run lower comp. ratio.
