To be true full, I really don't know if there are any regulations here regarding motor vehicle emissions. Basically it seems if it runs okay, its good. So there is no testing of light motor vehicles after they have been first registered. Even when the car is secondhand and imported when they are...
I like the idea of the welded in deflector as this can be customized in all possible ways to achieve the desired result without the risk of something breaking or falling off into the works. I will need to look for a set of heads to play with.
There are no HP or torque figures available as I live in Botswana and as far as I am aware there are no dyno's available here. I would need to take it to South Africa to do this but realisticaly it would be much simpler to test it on a drag strip (also in South Africa)after this current Covid...
In reply to rodrico's statement about a sharp observer noticing some thing untoward about the video clip I can only say this: I took the video my self with a Nokia N8 phone in one hand and operating the engine with the other. The video has not been edited,tampered with or otherwise modified in...

The wasted spark is as in 4 stroke configuration but is used to fire the oposite cylinder at TDC to crate the double firing. Like wise the injectors can be set to "two stroke" to fuel the opposite cylinder. The injector setting was not intended to be used this way but rather to supply more fuel...

Brian, really, what part of the "cryptic" link don't you understand? Is it Facebook or is it ian.crawford.100 or is it "Posts Sept 2014"? Please let me know so that I can help you.
Ex opens 90 BBDC, Ex closes 25 ABDC, Inlet opens 25 BBDC, Inlet closes 90 BTDC. Cam and crank belt gears are 40 teeth using stock belt (stock gears are 24 for crank and 48 for cams). The engine is basicaly stock apart from the camshafts, Bullit blower manifold and the ignition and fuel ECU. The...
Hi Brian, the engine can be seen running on facebook. You are correct in saying that the valve timing is half the duration as it previously was but it is force feed now. The short circuiting is not an issue, this is only for racing where fuel consumption is of no consequense. I have not run the...
Has any one got any experiance with two stroke poppet valve engines that they would like to share. I have built a Lexus 1uz V8 which is running as a two stroke. This project is primerily for increasing the volumetric efficiency for racing purposes. Any comments will be...
