Yet another comparison (air-gap carb spacers)

I'm personally not a fan of spacers, period. In the 70's when I was first starting out, I tried several sizes/types on a few different street/strip combo's. The results were so mixed between all of them, as far as power & drivability, that I just got frustrated with the whole deal and swore off of them. I found much more satisfaction changing intakes, but then again, I wasn't looking for a "hun" or two...lol.

Back to modern times :D, and the fact that your more focused on track times, i'd think the open spacer on the AG will still give you the best of both worlds. That intake is so strong down low, I think opening the plenum a hair will help upstairs more then it will hurt down low. I know others have had similar results with it.

Good luck! I know we've been thru the big intake go round for the 1/8th mile, and hopefully with the AG and whatever spacers you test, you'll find what you're looking for. :thumbrig:
