V-BAK vs PR-BAK" the Seat-of-Pants Dyno Reports
I hadn't heard before that the PR BAK produces more HP than the VBAK.
The PR BAK was developed forPR's modified 122ci normally-asiprated drag race engine with modified drag exhaust. It works fine on the 102ci 108ci 110ci engines but its flow pattern is engineered for the 122ci race motor.
The VBAK was developed forthe stock injection system on 102ci108ci 110ci and 122ci engines with or without aftermarket exhaust system, and due to the shape and length itdevelops an intake air pattern advantage on all the motors.
I don't want to say its cast in stone, but in my old mind I believe I've read more seat-of-pants dyno posts indicating Woody's VBAK develops more HP and TQ on 102ci 108ci and 110ci engines with free-flowing exhaust mods. Bets are they are so close it will take heads-up dyno work to tell the difference. Plus IMO Woody's kit looks a lot nastier bolted-on.
Okay chime in and let the "games" begin!
