The C4 version of the Corvette ZR-1 was nicknamed “The King of the Hill” for good reason. At a time when the standard Corvette’s horsepower was 245, the 1990 Corvette ZR-1 was powered by the new 375-horsepower LT-5 V8 which featured a 32-valve dual overhead cam. Looking back today, Corvette’s return to the world stage of sports car performance can be directly attributed to this special edition.
Corvette Racing driver Jan Magnussen made headlines last season when his battle at Laguna Seca with the #45 Flying Lizards Porsche ended with Mags going into the wall. We spoke with Jan prior to the start of the 2010 12 Hours of Sebring and asked him about the incident and whether he has talked with Jorg Bergmeister since the incident. We also asked Jan about his running the Nurburgring in a Corvette ZR1 last fall and if he thought he could be Jim Mero’s 7:26.4 time.

Long time readers of CorvetteBlogger know that I don’t many comparo stories. Although not perfect, the Corvette has proven to be MY favorite car time and time again and I don’t need to get into a dick measuring contest to prove it. But as we get close to Sebring, I started thinking about the fight between Porsche and Corvette and how all that racing technology transfers to street cars. I guess the folks at Porsche’s Excellence Magazine had the same thoughts and decided to find out what happens when you pit the ultimate street versions against each other.
As Corvette Racing gears up for the start of the 2010 American Le Mans Series, the team is releasing additional details regarding the changes needed for competing in the now unified GT class. The most notable change for the GT Corvettes is the new LS5.5R V8 engine. Built alongside its LS9, LS7 and LS3 dry-sump brethrens at the Performance Build Center in Wixom, this new LS7 based engine is slimmed down to 5.5 liters and delivers 485 horsepower at 5800 rpms.

In October, we posted a video claiming to show the fastest quarter mile time set for a bone-stock Corvette ZR1. That run of 10.851 @ 129.89 MPH was just eclipsed last week by Corvette Forum member “blownlt1&c6z” who ran 10.74 @ 133.21 mph in his bone-stock (including tires) 2009 Corvette ZR1. Both these runs happened at the same track – Maryland International Raceway.
This Wixom walk-through video was released in late November on Chevrolet’s YouTube channel. Master Engine Builder Don Henley takes us through the various stages and quality checks as a 638-hp LS9 is assembled. For us, the real magic comes when we see the interaction these builders have with Corvette owners.
Lingenfelter had their Corvette ZR1 test mule making quarter mile passes at Maryland International Raceway on December 7th and during one of the runs, the Corvette ran 9.81 @ 145.74 mph. This is believed to be the first Corvette ZR1 to see the 9′s on a quarter mile run.
