Intake Valve Closing Point: Critical for Maximizing Performance

Uncategorized June 20, 2017

A camshaft’s intake closing point has more effect on engine performance than any of the other three opening and closing points. The earlier it occurs, the greater the low-rpm cranking pressure. Early intake closing is critical for low-end torque, responsiveness, and for generating a broad power curve. It also reduces exhaust emissions while raising fuel economy.

In a four-stroke, internal-combustion engine, a cam’s intake lobe closing point after BDC on the compression stroke has the most significant effect on an engine’s operating characteristics. (Photo: Comp Cams)

As rpm increases, intake charge momentum also increases. This results in the intake charge continuing to flow into the combustion chamber against the rising piston far past bottom dead center (BDC). The higher the engine’s operating rpm, the later the intake closing should be to ensure all the charge possible makes it into the combustion chamber. But closing the valve too late creates significant reversion. It’s a fine balancing act.

In a perfect world, the optimum intake closing point would occur just as the air stops flowing into the chamber; would get the valve seated quickly and not waste time in low lift regions where airflow is minimal and there is no compression building in the cylinder; wouldn’t be so fast the valve bounces as it closes, allowing the charge to escape back into the intake port and disturb the next charge; and, with a hydraulic-lifter street cam, would ensure the closing ramps aren’t so fast they result in noisy operation.

Duttweiler Shoots for 450 MPH With LS Engine at Bonneville

Uncategorized June 20, 2017

<!–

George Poteet’s Speed Demon blown Fuel streamliner, the world’s fastest piston-engine-powered land vehicle as certified by the FIA, will be back at Bonneville this summer running a totally new turbocharged, 441ci, LS-based engine combination built up around Dart’s Gen-III LS Next compacted-graphite-iron race block and its aluminum Race Series 10-degree LS canted-valve heads. Engine builder and crew chief Ken Duttweiler explains the reasons for the switch from the car’s previous record-holding, small-displacement, Gen-I style small-block: “We wanted to move up to the ‘big-block’ streamliner class to go even faster and set yet another new class record, but the chassis isn’t wide enough. Dart’s new LS block is available with a 9.300-inch deck-height, which allows us room for a 4-inch-stroke crank. The tallest Gen-I race block is only 9.300 inches. We special-ordered the new block with Ford Cleveland-sized, 2.75-inch-od, main journals that allow a crank with plenty of journal overlap for supporting the power-level we’ll be making. Our engine will be 441 ci in a class that permits up to 500 ci—essentially, a big-block wrapped in a small-block envelope.” Duttweiler says the new architecture has the potential to eventually make 3,000 hp, “but right now 2,300–2,400 is all we need to pump our current FIA 438-mph two-way record with the old-style small-block another 20 mph.” When we recently stopped by the shop, the new Dart heads had just arrived. Check out the photos and video.

The Dart LS splayed-valve heads have symmetrical intake ports, unlike the previous-gen Dart splayed valve heads formerly run by Duttweiler on his Gen-I style small blocks. “I expect to see 460–470-cfm flow-numbers from the 368cc intake runners.”
The heart-shaped chambers on both the Dart Gen-I (left) and LS (right) are nearly identical. They use 2.300-inch intake valves—that’s big-block territory.
Ken Duttweiler is shooting for a 450-mph two-way average speed with his new LS-based 441ci engine combo.

Gallery: Diehard Long Haulers Of HOT ROD Power Tour 2017

Uncategorized June 19, 2017

HOT ROD Power Tour 2017 Is Presented By Chevrolet Performance And Driven By Continental Tire

HOT ROD Power Tour is not your local car show. It takes 1,000 times more commitment to knock out a full lap of the tour than to simply show up, park a car and fold out a lawn chair. We’ve probably said it 100 times so far in the last 10 days, but we’ll drop the line once more: Power Tour Long Haulers are some of the most diehard gearheads on the planet. 1,500 miles is a road trip many wouldn’t drive in a new car; Long Haulers do it in a classic––almost all of which lack A/C, cruise control, and helpful navigation. Heck––for probably 70 percent of participants, cup holders are a missing creature comfort! Relying on decades-old hardware, homebuilt engines, and all other mechanical accouterments long since out of date, these folks get it done, enjoying every minute of the weeklong ride. This is vacation for a vast majority, a 40-hour-plus withdrawal from their time-off bank to attend the ultimate mecca of motorheads. We captured as many Long Haulers leaving the last day of Power Tour as possible to celebrate their dedication, perseverance, and commitment to our hobby. Here’s to the Long Haulers!
