Street Outlaws No Prep Kings racer Justin Swanstrom has made some upgrades to Prenup. These changes took place before the filming of Street Outlaws No Prep Kings at National Trail Raceway in Hebron, Ohio.
Swanstrom is now using a screw blower. He announced in a YouTube video that he shared two days before the beginning of the Ohio race.

He tested the new screw blower at Darlington Dragway in Hartsville, South Carolina. He is testing there for two days before heading to Ohio.
“I didn’t think I was going to make this change until the end of this season or the new car,” Swanstrom said in the clip. But with us busting the intake, it cost roughly $7,500 to put the Pro Charger back together. I said to my dad, the last two races, we have sucked it up and blew up the intake. That’s the sixth windshield this year.
“The firewall is blown back and I told dad it is time to make the switch.”
Swanstrom said that they already had the Screw Blower components. He joins “Disco Dean” Karns with the screw blowers on the tour.
He said that it took Modern Racing one week to make the switch over.
