Competition Connecting Rods

Sunday, December 25th, 2011

Nothing undermines the reputation of a connecting rod maker more than a deficient batch of rods. He agonizes 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. (more…)

How to Set-Up a Stock Suspension Car

Stock rear suspension drag racing is without question the big buzz today, and we’re not talking NHRA-legal stuff either. Instead, the current fervor is all about quick street cars. This is the sort of car that dominates, in sheer numbers, any of the myriad fastest street car organizations. But in truth, it’s also a wonderful combination for bracket racing, grudge racing or just to have fun.  It’s also perfect for the Pinks All Out format, but that’s another story. (more…)

More Carburetor Mysteries Solved, Part II

Appearance Vs. Reality

Changing priorities during the 1970s and ‘80s combined with the EPA’s grand and glorious entrance into the automobile business, made fuel distribution especially important.  It is for this reason that some carburetors, which were used both as original equipment and for aftermarket replacement, differ even though they share the same model designation. New car emissions standards may have dictated internal changes not required on performance-type replacement carburetors produced during the same time period. (more…)

Drag Racer Thrashes Parts on the Moroso Performance Dyno

Wednesday, July 7th, 2010

Check out our stats from 10 pulls in one day.

The original “Drag Special” front tire from Moroso Performance (http://www NULL.moroso NULL.com/) has been a “must-have” item for decades, thanks to its light weight construction and lower rolling resistance. And that’s not all the parts maker is famous for. Since 1968, Moroso has pioneered the development of deep-sump oil pans, pan evacuation systems, vacuum pumps, and countless other performance systems and accessories.

Recently, the Drag Racer team was pleased to spend a day at Moroso Performance, where its team of engineers soundly thrashed a host of parts on the company’s DTS dyno. This aggressive project showed us (in real time) how a host of products have increased horsepower over the years.

Mule Engine Basics

The mule engine selected for this exercise was a 582-inch big-block Chevy provided decent results from most of the products tested here. However, it’s difficult to baseline such a wide variety of power producing items using one mule, as different combinations respond differently when applied to engines that put out either less or more grunt.
