Massive secondaries and fuel injection

Post by Speeder »

Probably nobody remembers this, but a long time ago I complained on this board about how with fuel injection, you no longer got the sound of the massive secondaries opening up on a 4 barrel carb, and how nice it would be if there was a way to run a pair of throttle bodies so that one would run for cruising, and when you mash the gas the second one would open.

Seems that's no longer an issue.

Huh, that's an interesting concept. A proportional controller for a second throttle body. Seems like someone would have thought of that long ago.

I remember hearing the secondaries coming in on my first four barrel car (Trans AM) - I had driven like a granny for the first two hundred miles just like the owner's manual said was needed for the "break-in".

The instant I hit two hundred miles, I floored it. It was awesome! The kickdown to first gear, the scream and then roar of the carb - I have never forgotten it. It wasn't long after that I opened the scoop and the sound was even better. I miss that sound!

I do miss that instant response - now you floor it and then wait for the computer to say, "okay, let's go now".

Manual adjustments for kickdown, pump squirters - ahh, the old days! LOL
