He did it. And did it. The transmission in your car isn't the same as the transmission the supercharged Bonnevilles get. Not nearly as strong.
I usually tell people that are determined to do this to have at least an extra $2k budgeted and sitting in the bank first. So when the trans goes, you're ready.
I'm already supercharged on both cars. Adding power to my FUN one cost me my trans in the long run. This is true for every car here.
The little ricers and RWD V8'* can be different. Ricers don't have much power to begin with, and are very light cars. RWD V8'* generally have stronger transmissions. We have heavy cars. This weight puts stress on the transmission.
