ASHTABULA - - Dawn and Kevin Cragon's TI Dyno Shop was filled with noise and lots of smoke Saturday as diesel pickup truck owners from four states came in for a performance testing event.

"This is the first time we've held the testing event. We couldn't get them all done, so it will be repeated next Saturday and Sunday," said Kevin, who opened his business at 776 Center St. in the city in 2004.

Cragon has chassis dyno floor model equipment used to simulate road conditions. Truck owners use the equipment to test their vehicle's performance, he explained.

"It's for tuning purposes, improving gas mileage and even bragging rights," said Dawn Cragon, who helped score points for the competition.

Cragon has a full-time job as a millwright with a Lake County company, but runs the shop as well, hoping it will flourish into full-time work. His next door business neighbor, Burt Brown runs a transmission repair and replacement center. Brown was a sponsor for the Cragons' show.

"We had trucks built from 1990 to 2007 here. A lot of guys spend money to beef up their vehicle to run and perform better on the road. The equipment also is used by race car customers I have," Cragon said.

Saturday's show was strictly for all-diesel pickup trucks. Cragon said he intends to hold other competition style events this year.

"I'm also going to be a sponsor at Thompson Raceway Park this year and have some advertising there for my shop. I'm getting a car ready for Dawn to race on the straight track there," Cragon said adding he was pleased with the turnout for the initial show.

Free food and prizes were given out to winners including hats, T-shirts, a case of Rotilla oil and car care kits. Cragon's shop sells and installs special brand turbos, superchargers, exhaust systems, intakes, gears and parts for upgrading vehicles.
