Everytime I've used a TR it has lowered RPM peak HP and torque comes up across the board. J.Rob
Off topic, I know.......
As an example of how the engine combo, and the particular TR being used can impact the results:
540 big block(4.375x4.500) with ported 440-1's and a 281/292-112 roller cam......
Indy 440-2 w-2" 4500/4150 adapter and 1150 carb:
Peak tq @ 5300, peak hp @ 6800
Indy TR with 2x non-hp 4500 1050's on it:
Peak tq @5700, peak hp @7300(end of the pull)
Peak to peak the TR was 20ft/lbs and 33hp better.
At 7300 the TR was 54hp better.
Tested back to back.
