Broken Valve Spring? Exhaust pops I am running a TR224-112, hardened push rods, 918 springs with Ti Retainers, FLPs, OR pipes, magnaflow catback.
I hear a ticking noise of the passenger side of the engine. The car excellerates fine and pulls just as hard under WOT. When I shift at higher RPMs in between gears the exhaust pops, and downshift over 3k it pops.
Its not an occasional pop, its a series of pops. It started one day as some pops here and and the next time I drove the car it started popping a lot more--havnt driven it since

How long have you been running long tubes without cats? It just recently, then that could be the problem, you could just be getting those backfires because of no cats. Also, do you have your car tuned yet after the cam install? That could contribute to your problem.

Been running OR Pipes since the summer before the cam install. Exhaust has always sounded fine. Absolutely no changes have been made since the popping started.
Car has been tuned also.

If it is a broken spring can I run 921s? This month I am installing the TR 224/227 .563/.569 114LSA cam with an ATI D1SC. Wondering if the comp cams duals might be a better way to go? Or would they be too much spring for that cam?

no such thing as too much spring for a cam... for lifter yea... but 921s are designed for stock lifters... the 921 would be way better for your application and piece of mind... that charger is gonna put some hurtin on ur valvetrain i wouldnt run anything but dual coil springs ... your gonna make lots of power
