Every year in early December, the Performance Racing Industry (PRI) tradeshow sets up shop in Orlando and invites all the major manufacturers in the racing industry to show off their wares. And for us it's like a racer's giant toy store. The show is all about racing, so there's no time wasted passing by booths of giant rims or weapons-grade stereo systems. That's cool and all, but we're all about the racing and PRI has it.
It's one of the two opportunities available to check out all of the great new racing hardware available. The other is, of course, the International Motorsports Industry Show (IMIS) in Indianapolis. We were at both shows this year and, in most cases, got to lay our hands on a whole slew of new parts so we can make a real-world judgment on whether it's really all the advertising materials say it's cracked up to be.
So without further ado, we bring you part one of the absolute best of what we found over five long days at the PRI and IMIS shows. Some of it can help you go faster, some of it can save you money, some of it can save you time in the shop or cut down on DNFs, and some of it's just for the fun of it. More will come in next month's issue,but we think all of it's pretty cool. Hopefully, you'll be able to find something in all of this to make your racing life just a little bit better. Now go out there and have a great season of racing!
Dart's new 9-degree cylinder head casting had already proven its worth in Super Dirt Late Model racing, and MBE Cylinder Heads and Manifolds has put its own stamp on this race-winning head with its custom porting touch. MBE has developed custom porting programs for everyone from NASCAR Sprint Cup teams to Top Fuel drag racers, and its cylinder heads produce some of the best flow characteristics you'll find anywhere.
MBE's Dart 9-degree head is capable of flowing 425 and 280 cfm through the intake and exhaust ports, respectively, while also keeping the port velocities high for good throttle response. MBE also offers a custom ported intake for this head for even better performance.

Vintage Look, Modern Protection
G-Force Racing Gear's new Pro Vintage full-face helmet has that great old-school look that many racers prefer without sacrificing modern safety standards. The Pro Vintage has earned the new SA 2010 rating for maximum protection and the full-face design provides plenty of visibility.\

Quarter Master says its new carbon-fiber driveshaft (intended for Dirt Late Models but applicable anywhere else a CF driveshaft is legal) is the lightest on the market. For example, the 39-inch-length driveshaft weighs less than 4 pounds, which is 1.5 pounds less than the typical CF driveshaft of the same length and 2 pounds less than a similar driveshaft constructed from aluminum. The reduced moment of inertia this weight reduction provides should provide a measurable advantage during acceleration.
But the lighter weight doesn't come with a durability penalty. Quarter Master says the 3.0-inch CF driveshaft has tested to be able to handle more than 4,000 lb-ft of torque loading. For additional safety, the driveshaft has a sacrificial outer layer that is non-load bearing, so any superficial damage it withstands won't create a catastrophic failure.
