Torque multiplication through a slanty-streetTC is fleeting, and the % is very small and on a 145 hp engine at 1800rpm amounts to what? 2 or 3 guys pushing on the rear bumper? Ok, maybe a wee bit more......
A higher stall can provide 30-60% more torqueX depending on what you
start with and what you install,and 3.55's are 28%+ over 2.76's,just basic math.
Lets say 15% from a new TC,and X that by 1.28....213.44hp over 145hp,.............
the parts have to match,don't stall an eng. at 3000 when the torque curve falls at 4000.
BTW, has anybody seen the OP?
