How many of you fell for the direct injection meme?

what's the difference between gdi and standard fuel injection?

Direct injection get so much carbon buildup in valves it lowers the hp

You can run high compression and leaner fuel ratios with out having to worry about the charge pre igniting during compression.

This meme isn't funny and it never will be.

Oily air from the pcv will put carbon build up on the valve.

They're basically using diesel technology on a petrol motor so they can run huge compression ratios on regular fuel without pre detonation.

It's not a meme when it makes more power on production cars with the same emissions outputs.

PCV systems create oil deposits in your entire intake system, not just the valves. In a regular port injection setup, the fuel will clean the valves, which is enoguh cleaning. This means you could put a plate-style single point injector on an intake manifold, and periodically use it to clean the entire manifold. Iirc Ford uses twin injectors (one port injector + one direct injector) partly because of this.

Or, you could just put a catch can in there. Way easier, and it'll keep your intake cleaner than both DI and port injection.

If you just install a methanol injection plate, it'll easily clean your entire intake.

atmo vent that fucker, that's how they used to do it in the good old days!
