South Side Performance GTR820RR Turbo Kit

First ever R35 GT-R to hit 645hp and 645ft lbs of torque! John Turbo over at Samurai Speed claims 633hp with a combo HKS GT570 kit + Cobb hybrid setup. The SSP kit hasnt even been tuned yet, this is only stage 2.

South Side Performance makes 645awhp / 645awtrq from its GTR820RR turbo upgrade on a mild bolt-on GTR with OEM fuel system

Sioux Falls, South Dakota (January 23, 2009)

The last few days have been extremely exciting for the GTR community as new benchmarks have been set many times over, but today represents something truly amazing. Very few GTR owners have pushed their cars so hard that they could find the true limit of the stock fuel system, and today we found yet another aspect of the GTR that is truly amazing. Today we pushed a GTR to find out just how much power the stock tune and fuel system could really handle and the results were truly staggering. We bolted our GTR820RR kit and new RS down pipes to a largely stock car and after taking the new turbos up to 21 PSI we were amazed when the dyno winded down and the numbers 645awhp and 645awtrq appeared on the small screen.

Modifications to get it to this power include:

SSP GTR820RR Turbo Upgrade Kit
SSP RS Downpipes
SSP Ceramic Intake manifold spacers
SSP Hardpipe Kit
HKS Kansai midpipe/HKS Kansai Ti Muffler

This represents a nearly 130 awhp and a 142awtrq increase over the baseline dyno taken when the car arrived at SSP (Baseline was 516 awhp and 503awtrq). This is especially impressive because there was absolutely no tuning done to the car and the system was able to learn and compensate for the massive increases in air volume provided by the new turbos without any issues or sputtering of any kind. With a tune and a bit more fuel, the sky truly is the limit. For the moment, it appears that this GTR just might be the most powerful R35 in the land, and we have only just begun!

This is only a start. This is just an increase in boost over the last results. Imagine what a tune would do to this setup.

To go with all of this new power, TRANSMISSION AND DRIVETRAIN UPGRADES will be unveiled MONDAY, JANUARY 26 @ 5PM PST, and new pieces released later that week.
