Video: Boosted Camaro Sets New IRS 5th Gen Quarter Mile Record

You know what they say about records – and as of recently there’s a new holder of the title for “World’s Quickest IRS 5th Gen Camaro”. The Car is independently owned by Mrs. Terri Mensing, and was designed and built by Ohio’s IPS Motorsports – the same guys who helped Mark Carlyle build and tune the record breaking Atomic Fusion C6 Z06.   

In a thread on Camaro5 we learned that the outing was originally slated to be just a test session at National Trail Raceway in Hebron, Ohio. In spite of the cold weather, driver Bob Williams quickly brought out the best in the gray 5th Gen, and a string of high-8 second passes made the record look more attainable.

After three runs to work out the bugs, Williams pushed the Camaro to 8.68 at 165 MPH on the 4th pass of the day, and broke the current record belonging to American Racing Headers/Farks Supercars who’s IRS 5th Gen ran an 8.72 at 156 MPH at last year’s LSX Shootout. But the IPS team knew there was even more left in their car, and on their fifth pass the Camaro ran 8.56 at 166 MPH. Why stop there? So on the sixth and final pass the current record was finalized with an 8.47 at 168 MPH.  

The motivation for those stellar time slips comes from an IPS built twin-turbo 427ci LSX with cylinder heads and the intake manifold from All Pro. An Aeromotive Pro Series fuel system keeps the boosted LSX happy, and the power gets transferred through a Turbo 400 transmission built by RPM on its way to a DSS Ford 9-inch center section that still uses the stock IRS configuration. Traction is provided by a set of 15-inch Weld wheels wrapped in Mickey Thompson Drag Radials.

Who says the IRS is only good for turning corners?
