Team owner and driver Dan Gardner was the fastest Touring Car in MotoIQ's Project Scion tC, with Stout taking second position in its sister car.  Neither driver had ever driven the course before, with both of the DG Spec drivers coming up to speed quickly on the unforgiving Long Beach street course.


 

MotoIQ Project Sentra Spec V

Project Nissan Sentra Spec-V part 5; Lessons in Geometry

By Mike Kojima

Although Nissan hyped up the Sentra Spec-V as a performance sedan in its marketing campaign, in truth the car was a little more than a piece of basic transportation with a few performance enhancing bells and whistles.  The car was cursed with a crude beam axle rear suspension and a McPherson strut front suspension whose geometry was designed around efficient packaging and relentless understeer rather than performance.  Because of this, the Sentra is at a significant disadvantage in the handling department when compared to its FWD rivals, mainly Hondas, the Scion TC and even the Infiniti G20.  Despite of all this, we at MotoIQ are always up to an engineering challenge and we set about to rework the SE-R's suspension to attempt to make it a little more competitive.

Understanding the EFI process

EFI 102- Understanding EFI Processes Through Detailed EFI Sub-system Analysis

By Christian Krahenbuhl

This is the second of four EFI articles from Cobb Tuning. This article will provide a more precise focus on modern EFI Systems; introducing you to various closed-loop control systems and explain how some of the basic calibration/tuning feedback systems are used. We will again introduce you to the new terminology and rhetoric used by tuners, engineers, & engine calibrators. This article will use more advanced animations and hands on exercises (with a spreadsheet) to educate you as to how calibration of modern EMS is done. We will breakdown the EMS into sub-systems; we will look at separately understanding and calibrating the Fuel System, the Ignition Advance System, the Boost Control System, the Camshaft Phasing System & Other Control Systems.

Flashback Friday -  The Time Machine: Inner Secrets of Sierra Sierra's Record Holding Time Attack EVO VIII (video inside)

By Mike Kojima and Eric Hsu, photos by Jeff Naeyaert

We are taking a look back at 2010 and are bringing you some of our best stuff of the year this week. We feel that Sierra Sierra bringing the North American Time Attack record back into US hands by solidly beating the long standing record set by the HKS CT230R is the industries highlight achievement of the year worthy of revisiting,

At the 2010 Redline Time Attack season opener at Buttonwillow the Sierra Sierra EVO made history by turning the fastest lap by a time attack car around Buttonwillow Configuration 13 CW turning a 1:43.20 breaking the long standing North American Time Attack record set by the exotic HKS CT230R set in November 2007 of 1:43.523.


 

Museum Autovision Rotary nerd heaven

Technobabble - Rotard Heaven

by Dave Coleman

For about a decade, the rotary engine looked ready to take over the world. Dozens of companies were developing the powerplants in an effort to exorcise the rotary's demons and realize the potential of its simple concept and compact proportions. Almost all of them failed, and the whole exercise was relegated to a historical footnote.

Here, in a small museum about an hour south of Frankfurt, is a glimpse into just how big and complex that footnote should be.

By Jeff Naeyaert

Normally we don't do Project "previews" here on MotoIQ, but normally Mike hasn't ground down 1 of his only 2 typing fingers in a power sanding accident rendering him unable to write and normally the FedEX guy doesn't bring us as exciting stuff as he did last week!  So here it is, an introduction to Project V8 RX-7! 


 

Brian Lock's Cobb Tunning GOTO racing Nissan R35 GTR

Locked and Loaded, Cobb Tunings Time Attack Nissan R35 GTR, videos inside!

By Mike Kojima, Photography by Jeff Naeyaert

We have been keeping an eye on the GTR that has been campaigned by Brian Lock and GOTO racing under the Cobb tuning banner.  Although the car runs in modified class, we noticed that it was starting to come together and was turning lap times just a few seconds a lap slower than the big guns in unlimited class like Sierra Sierra, Crawford and FXMD.  We expected to find some really exotic hardware when we examined the car; after all we could not see how the huge GTR with its crushing weight of 3800 lbs could even come close to being competitive in any sort of racing without some exotic work.

TORRANCE, Calif. — This past weekend, at the World Challenge season opener in front of an estimated 150,000 fans, the DG-Spec Scion road racing team proved again that Scion is the real deal, even at the top of the pro ladder.  Three podiums, and five awards of distinction were racked up by drivers Robert Stout and Dan Gardner, driving the number 18 and 36 DG-Spec Scion tC Touring Cars, respectively.
