Default Harmonic Balancer

I'm having the harmonic balancer replaced (as well as the belts that broke when it went out) on my 2000 C5. I'm trying to make peace with the $1100 groin punch by figuring out if there's anything else (relatively cheaply) that I can add or replace, performance-wise, while they have the thing disassembled. Any and all advice is greatly appreciated! Thanks in advance to the greatest sports car enthusiasts on Earth.

I had posted a querry about clanging and rattling on my 43K mile C5. No one had any direct answers. It turned out to be a harmonic balancer. Being replaced now for about half of what your paying by a corvette shop in Tampa. I had never heard of these going bad on C5's but apparently it is common.

There are other idler pulley's there that you might want to replace while it is apart - AC pulley idler etc.

Huge thing would be to do an UNDERDRIVE balancer and pulley's which'll give you some extra HP's

Also could do a Electric Water Pump and a Low Temp Thermostat too!

Hi-Flow Airbridge and or a CAI (My suggestion is to do a VARARAM )

A De-Screened MAF Housing

To top it off get a handheld tuner and adjust the fan on/off temps to take advantage of anything you do to make extra HP and TQ or get a DYNO tune which will net some good results

Ported TB would be good too, but can be done later

That should be good!

Thanks,Matt

While the balancer is off, go ahead and have a split-timing chain cover installed. That way, if you ever want a cam, you won't have to pull the rack and the balancer! Also, why not replace the oil pump with a high-volume pump while its off too?
