Howdy,
Here is my deal, I'm building a dual purpose street strip motor that I'm hoping to make about 600hp+ off of, basically whatever I can get away with without turning the motor into an improvised explosive device. .......... Can I use a machined to neutral balance stock balancer hub and flexplate and if I had to get an aftermarket one of either, which should I get?
After a couple comments about machining a stock balancer to make it neutral balance, we did some checking. First, I have replaced a few stock balancers on street GN's that have cracked, worn the keyway and ruined cranks. For someone to machine lots of material from this cast piece and use it in a performance motor is asking for trouble.
The BMS piece is a hub, NOT a harmonic balancer. It will do nothing to dampen the crank harmonics and flex.
At this point, to answer part of your question, only BHJ make a performance Buick balancer with a trigger wheel.
Many broken and cracked stock flexplates that have been mentioned on this board can attest to the lack of strength it contains. To remove material or modify it will not help it live in a high performance application. We use JW flywheels in this application
At 600+ HP, you are at 3 time the level these stock parts were designed and built to withstand. When they let go, lots more $$$$ damage is done than doing it properly in the first place.
