Recognizing the specialized needs of competitors with nitromethane and alcohol-fueled engines, technology leader SCE Gaskets has published a handy catalog listing the state-of-the-art gaskets for T/F, F/C, TAD, TAFC and Pro Mod racers. The new SCE Fuel & Alcohol catalog covers a wide range of cylinder head and block combinations employed in both NHRA “Big Show” and Nostalgia competition. These span from early Chrysler Hemi and Big Block Chevy engines to the latest aftermarket offerings from AJPE, BAE and others. Nearly two-dozen combinations are listed.

In addition to a detailed listing of SCE’s popular Pro Copper head gaskets, which come in seven thickness for nitro & alky applications, the catalog covers the firm’s unique Accu-Seal Pro composite/steel core gaskets for oil pans and valve covers that are accepted by NHRA for use in these high pressure environments and won’t blow out. Also listed are special embossed copper and reinforced composite exhaust gaskets, breather gaskets, and rear main seals. The catalog also shows blower base and inlet gaskets for all popular supercharger types from 6-71 through 14-71.

The catalog is available free upon request by calling toll-free 800-427-5380 or visiting the firm’s website at SCE Gaskets is an NHRA Official Sponsor and posts contingency awards for its Pro Copper, Titan and patented ICS Titan head gaskets at all LODRS regional and divisional events.

World’s first sequential transmission for Corvette and Camaro

MTI Racing has pioneered the world’s first 6-speed sequential transmission for C5 and C6 Corvettes. Its chief purpose is to accomplish exceedingly fast no-lift gear shifting.

Using the original Tremec gear case, MTI converts the internals and the H-pattern shift mechanism to full sequential operation. Introduced initially for the Corvette, it maintains the original mating surfaces and operates with the original mountings, clutch, slave cylinder, and drive-shafts. Its two key advancements are its strength and most of all its shifting speeds.

Shift times with the original equipment require about a second. With dog engagement shift times are reduced to 0.35 to 0.45sec, depending on shift lever length. But when accompanied by an electronic paddle-shift mechanism, this dog-engagement design will affect a shift in 10 to 20 milliseconds (100th to 200th of a second). But this system’s real superiority is not just revealed in acceleration—its lightning fast no-lift up-shifting ability—but for track days and road racing, its downshifts through 6th, 5th, 4th, 3rd, & 2nd are all completed in less time than it takes to brake. Thus its startling down-shifting capability promotes greater vehicle stability under braking and corner entry.

It may appear MTI’s new sequential technology has suddenly burst upon the scene, but it hasn’t. In 2001, when the concept of track days had just started in the US, Corvette owners commented they were using only four of their six gears. At that time MTI’s Reece Cox addressed the issue by providing a special ring and pinion, which also improved acceleration. Later he introduced a new close ratio gear, which allowed Corvette owners to use five of the six gears during track use. Then about four years ago, while still using the conventional H-pattern shift gate, MTI Racing introduced dog ring engagement to the Tremec T-56 gearbox casing. The ratios are as follows: 1st 2.437; 1.611; 1.228; 1.00; 0.875 and 6th 0.777.

By necessity the sequential system introduces a barrel arrangement that replaces the conventional H-pattern internals, while cleverly employing the same above-mentioned gears. Therefore all existing MTI Racing’s H-pattern dog boxes can be updated to sequential technology if desired.
Lastly, the firm’s electronic paddle shifting mechanism is in its final production stages.
