Pro Auto Tech's Mongoose 400

Pro Auto Tech's Mongoose 400 - Completed February 4, 1999

Parked in the service reception area waiting its turn. The hood is up because we are trying to cool down the engine so work can begin ASAP. Hot aluminum and tight bolts sometime do not get along.

The installation of Pro Auto Tech's Mongoose 400 performance package was performed at Ray Huffines Chevrolet - Plano, TX by their Corvette Tech Specialist John Culter. The service consultant that handled getting the car in and out for me was Frank Conti. And Last, but not least, James Orman, Manager Fixed Operations, put the whole thing together for me. If you need work done on your Corvette and you are anywhere near Dallas, Texas, this group of people is phenomenal. They treated my car as if it where their own.

On the DYNOJET at L.G. Motorsports before making the Pro Auto Tech enhancements
Approximately 346HP (corrected) and 306 ft.lbs. torque

On the DYNOJET after making changes
Approximately 380HP (corrected) and 340 ft.lbs. torque
You can tell the "after" picture by the exhaust!

In both pictures, that's Chris Siggins of L.G. Motorsports getting the car ready to dyno. I will post the charts from the dyno as soon as I can get to a scanner so you all can check my math (smile). However, page down a little and you will find the numbers from the dyno runs.
