Nelson Racing can sure build some powerful engines. Take for example the twin turbo beast they built for Mike Vietro’s Mosler MT900S. The engine was proven to do 1,635 horsepower and 1,481 lb-ft torque at 5,600 RPM on race fuel. Under normal pump gas the engine can still get over 1,000 horsepower. Not much is said besides it is a LS7 motor with Nelson Racing twin turbo package.

On May 2007 a special Lingenfelter Corvette did a standing mile in 25.12 seconds at 226.25 mph. The Corvette was able to reach this speed because of its massive 1,300 horsepower on 23 psi of boost from a 427 cubic inch twin turbo engine. But even on 93 octane fuel the Corvette put out 1,100 horsepower and did 0-200 mph in 18.34 seconds. Someone did the math and based on the horsepower and drag of the car it was estimated the car could do 300 mph. Of course math doesn’t always translate to reality. It would be great to see what this car could do at the salt flats and see how close it could really get to 300 mph. Besides the engine the only real modifications were safety such as a roll cage and 5 point harness. This Corvette had full interior, stock seats, air conditioning, factory suspension, and Michelin Pilot Sport PS2 on HRE 840R wheels.

HKS has their GT570 turbo kit out and it bumps up the power from the factory 480 hp to 570 hp. We are now seeing more and more aftermarket companies develop their kits for the GT-R. These companies are going to push the envelope farther and farther until we see some unbelievable numbers. If history is any proof we will see some a very robust aftermarket catalog for the GT-R.

Ford says there has been a flood of inquires from UK drivers for the 2009 Focus RS and has reportedly taken 1,000 orders. I have no idea why? It has an engine that puts 300 horsepower to the ground through a 2.5 L turbocharged engine. Its basic body looks very sporty but not too crazy. The fact that it is factory turbocharged will allow a lot of room for aftermarket parts and tuning. Even the green paint seems to be a hit with 40% of orders asking for the color. I sure hope they bring this to the United States.

Hyundai will have one of their new Genesis coupes tuned by HKS at SEMA 2008. There is no mention if HKS used the four or six cylinder model but it would seem more likely they would use the four since that comes factory turbocharged. Cars looking like this will do a lot to change Hyundai’s image. Check out Jalopnik’s link below for more details.
