You tested 555 yellow tops on a series 1 L/ plenum and they work? I'm pretty sure people here will be glad to here that, if thats what your saying?
Don't know what colour and they were series 2 740s tested using a series 2 rail on a series one lower plennum and yes they work perfectly.
So far NONE of the videos and the the photos are close to showing whether the SARD spray pattern is good or not. Have a look at the US video. All he did was bolt it to the lower plenum and show it squirting out. Ummm thats not how they work. Where was the pipe setting up the vacuum venturi feed hole from the lower plenum to the injector hole? Wasnt there was it !!! Thats why the SARDS still work. When the venturi hole is working in the engine. It sucks the spray pattern down the injector channel. This elongates the spray pattern a lot. Poor testing methods lead to poor conclusions.
We shopped around.. and researched major fuel inj companies... RC Engineering were a pleasure to deal with.. cheap extchange rate.. cheap shipping and they have an injector to suit every application. Pick of the bunch were 750cc's gives u more scope for when u get a bigger turbo or run nos... this firm also designs pumps and regs to suit. Cheers Frank
I wondered that too Graham. How accurate could the results be if they were not performed under accurate conditions. There is a lot of airflow taking place when these injectors are firing so to me the results are inconclusive.
