6/6/19 Update: It was fun while it lasted!!!
Well, I set out early this morning to take the Malibu for some tuning at Mike Norris Motorsports in Plainfield. About 30 outside Plainfield, one of the tires on the trailer decided to disintegrate. Luckily there was a spare tire and that a buddy recommended bringing a floor jack and lug wrench. I want to thank the Indiana state trooper that pulled over and assisted.
I finally made it to Plainfield and to Norris Motorsports. I got the car unloaded and Mike proceeded to strap the Malibu down on the rollers. With this being a fairly fresh build, It had only been on two one hour trips and no faster than 65mph. Mike let me know that he’d eventually take it to at least 120mph. The first run he quickly took it to 90mph and and let it coast on the rollers, this was to let the rearend warm up. Then it was time to start seeing what this stock LS engine could do. It didn’t take him long to get it up to 120mph and everything sounded great, but as soon as he hit 122mph, the driveshaft came apart. Luckily everything stayed in the car and the damage was minimal (driveshaft of course, small dent in the floorboard and exhaust pipe) most importantly, no one got hurt. It could’ve been a whole lot worse. It’s hard to say what exactly caused the driveshaft to come apart (too much RPM for that shaft or possibly the inner seatbelt bolts that go through the transmission tunnel were maybe a little too long and the torque of the car caused the driveshaft to come in contact with the end of the bolt, cutting the shaft). Unfortunately, no backup driveshaft, the tuning cession was quickly over and Mike could only take the data from that run to set a conservative tune. Mike and his guys then helped load the car back on the trailer, so I could look go look for a tire store (trailer spare tire) and start heading back home. Once I got home I made a quick call to have another driveshaft made, so I could try and make it to an event Friday evening.
First and only run: 338 hp and 357 torque
The day could’ve went a whole lot better, but the Malibu will live to to go play another day!
Friday 6/7/19 Update: Don’t call it a comeback!!!
I got up Friday morning and made a trip down to Chandler In. to pick up the new driveshaft from Perfection Driveline. Got back in time to install the driveshaft, go for a quick road test and then wipe down both the sedan and the vert before heading down to an art/wine/cruise-in event on our Main Street. Even though it rained an hour before the event, we still had a great crowd. I always get tons of compliments on both cars.
