Fastest Street Cars Boom Mat Install

DEI Boom Mat Article in Fastest Street Cars MagazineWith over 550 horsepower, no air conditioning, and long tube headers, we knew heat and noise could make for a toasty time driving the streets of sunny California. After doing a bit of research we called up our friends at Design Engineering Inc. in order to try out their new line of insulation/sound deadener and ultra light carpet padding, named Boom Mat. The line of insulation and sound deadening materials include a mat that you “roll”, or press, on all your sheet metal panels, a spray on formula for the hard to reach areas and lightweight carpet padding. Boom Mat is specifically designed for automotive use and it serves two functions, to keep engine heat out and to reduce noise vibrations. While we don’t want our muscle cars to sound like a Prius humming down the road, we also don’t want to feel like the car is about to shake itself to pieces while sweating from every pore in our body...

Greenspeed Demolishes Record

Greenspeed Team Sets RecordGreenspeed officially holds the record as being the World's Fastest Vegetable Oil Powered Vehicle!!

November 12-13, the Greenspeed team ventured to the El Mirage Dry Lakebed just north of Los Angeles, CA for the final Southern California Timing Assc (SCTA) event of the year. On Saturday the 12th, Dave (driving) was very nervous sitting on the start line because it was the very first time the truck was going to move while being powered by vegetable oil. He put it in gear and proceeded down the 1.3 mile course to smash the existing record of 98 mph with a run of 139.882 mph. The team followed that up on Sunday with a run of 155.331 mph. Hopefully high enough to stand until we make it back to the salt flats in August of 2012 for Speed Week. At that point, the team intends to challenge the existing petroleum record of 215.091 mph, with vegetable oil as a fuel of course! We hope to also find a bio-diesel supplier before then as well, so we can fill the tank with that and get that record too.

Matt Handwork At Camomax Racing Runs a 9.95

November 19, 2011: DEI's own Matt Handwork runs a 9.95 @ 139 mph 1/4 mile at South Georgia Motorsports Park.

Matt utilizes our Ny-Trex Diesel Nitrous System on his 6000 lb., Duramax Diesel powered, Single-Turbo, stock-chassis, 2003 Chevrolet Silverado LB7 pickup truck.  So much for aerodynamics and minimum weight…horsepower and torque shall provide the victory!

Idaho Rob Coddens & Max'd Out Race Team

Maxd Out Race TeamRob Coddens recently wrote us detailing his 2011 Diesel racing season, and offered feedback concerning his use of the DEI Ny-Trex Nitrous System and DEI Titanium Turbo Shields. He writes:

"We wrapped up our 2011 Diesel race season and the DEI N2O system and Turbo blankets worked flawlessly in our World Record holding 4x4 drag truck.  Amazing the abuse I put these turbo blankets through while propelling a 6,000 pound, 1350 RWHP, 4 x 4 diesel pickup truck down the ¼ mile running 9.3 second ET at 149+ MPH.

With the size of the turbos we are running, to achieve this performance level on a diesel engine, the blankets help tremendously with spooling on the line and keeping the heat in where it belongs for added boost and power. The N2O system worked beautifully and without any problems..."
