Forever Blown

Currently, there is no premium supercharger that has evolved more than the TorqStorm. Of its sporting credentials, its greatest attribute probably lies in low-end torque. In this area, it has taken its most substantial leap forward. You don’t actually need more than 1850rpm on the clock before it will summon up much of the torque it possesses and it will continue to generate it all the way to 6500rpm.

Breakthrough Button Designs for Pro Mod, Big Turbos and Top Ring Placement Advice. A Denver racing piston specialist has just announced unique piston pin retention buttons. Its latest design for pro Mod and big turbo racing engines incorporates a radial locking feature. The advent of the piston button and its subsequent popularity came about because of the convenience it offers.

World’s most powerful Y-block

“To the best of my knowledge,” said Jon Kaase, “prior to last year’s Engine Masters Challenge, the most powerful naturally aspirated Ford Y-block engine produced around 600 hp.” This enduring feat, however, was substantially exceeded on January 17, 2016, when Kaase’s efforts raised the peak power record to 709 hp @ 6,300 RPM and 748-lb.ft. of torque at 5,400 RPM.

Competition Connecting Rods

24 things you need to know. By Sam Logan: Nothing undermines the legitimacy of a connecting rod maker more than a deficient batch of rods. They agonize constantly about heat treatments, high revs, heavy pistons, heavy pins, the number of race laps between rebuilds, but probably most of all whether or not nitrous is being sprayed. It’s a complicated business determining minimum weight while yielding maximum strength, enough to withstand the abuse sustained by the average race motor.

Tips to Tune a Clutch for Competition

Sometime last century, engine builder Jon Kaase declared that for every 1/10th change in barometric pressure, engine output is affected by around 10 hp. The adage changed the approach to clutch adjustments, and adept crew chiefs have since followed the rule.
