exhaust bottleneck debate

Q&A regarding engines, turbos, and intercoolers and power upgrades

TECHNICALLY, the 4" dp (if it's actually 4") wouldn't be the bottleneck. It would be the rest of the 3" exhaust, assuming it is hurting flow.
A few months back in SCC there was a street legal Supra with a full interior, and he was running 9.5 in the quarter mile. He had a 5" dp, and 3 1/2 or 4" exhaust. Maybe he could've been even faster with a smaller dp :shrug:

And Bryan, you never know what you'll start when you ask a question.
That's part of the fun of this place. :D
