While the expansion characteristics of a forged piston normally dictate increased cylinder-wall clearance, the Speed Pro replacement pistons use slotted oil-return grooves in the oil-control ring ...
When asked if he wants a piston ring set with moly, chrome, or cast iron faced top compression rings the mechanic often returns the question to the jobber salesman by saying, "What should I use?" There is some confusion in the trade as to what type ring set should be used.
Use of Nitrous boost of 150 HP and up will require the HellFire rings, which are made of heat-treated ductile iron base product. These rings are made to take the extreme heat of Mega Doses of Nitrous Oxide. For the Speed-Pro Ring Sets use the application guide to identify your vehicle make, engine size, year and cylinder bore size.
Summit Racing and Total Seal explain the dynamics of piston rings and the how to make the right choice for of rings for your next engine build. ... Here is one step you best not forget! Proper ...
These kits are for use with pistons that by the rules are required to have a ring groove combination of 5/64 5/64 3/16.Through the innovative use of specially designed rings and spacers the ¡°stock¡± class racer can take advantage of the narrow, light weight, low drag rings that the ¡°Pro¡± classes have successfully been using for years.
The pistons, like the times, they are a-changing. Not all of that change, however, is immediately applicable to building a traditional hot rod or muscle car. Our goal here is to survey the industry, find out what’s new, and help you decide what can help your builds—and what’s best left to the hardcore racers.
The Piston To work properly, thin rings must be absolutely flat with no runout. According to Gillis, “Rings seal at the bottom of the piston ring groove as well as the outside perimeter of the ring.
A lot of the best team use our Red Line assembly lube tubs and we finally released a liquid version last week. It's a personal preference, as some guys use the tubs in the trailer when they are building racks (it sticks well to the parts), putting it on skirts, rings, bearings, etc.
Gapping and correctly installing piston rings is one of the most important parts of engine assembly. Here's how to do it right. Piston rings perform a number of duties in an engine: They seal combustion pressure and gases in the chamber, preventing them from passing by the piston and into the crankcase where they can only do harm.
This is because metric ring setups have no standard radial dimension or the depth of the ring as it goes into the piston groove. That means that the pistons are machined to accept a certain dimension ring and the ModMax rings are that dimension. Start using different rings and they may not work.
