When Mercedes decided it was time to give the SLR supercar a boost, it created the SLR 722 edition. The odd labeling of the special edition model caused many to believe the ‘722′ number represented the horsepower output of the car’s supercharged 5.5L V8 engine, while others believed the car’s production would be limited to just 722 units. But they were all wrong. The odd title in fact comes from the 1955 Mille Miglia, where Stirling Moss and Denis Jenkinson beat out favorites from Porsche and Ferrari to take victory in a Mercedes-Benz 300SLR. The car was wearing the number “722,” which indicated the 7.22am starting time of the race.

Last year Mercedes tuner Renntech set about ending the confusion by boosting the output of the supercar to 722hp (538kW) – up from the regular 722’s 650hp (485kW). The original PKG1 kit included upgraded intercoolers, a larger crankshaft pulley, and custom ECU software to reach that power level.

The Florida-based tuner has now released its PKG2 kit and this time power has been boosted to 740hp (552kW) at 6,400rpm. The car has also been given a slight visual update with Signature 10 spoke wheels in SLR offsets and 3 finishes.

Pricing for the standard PKG1 starts at $12,990, while the PKG2 kit will set you back $26,990. Renntech also offers bigger 20in wheels for $1,950 each and owners also opt for more powerful brakes at additional cost.

When's enuff enuff for Benz?

[Corrosive]

Love it.... Price is not too bad as well considering that the car costs about a half a million.

650-740hp
-larger intercooler
-ECU rewrite
-larger pulley

The question should be... 90HP upgrade for 27k will be worth it?

When you have that much money, would it matter?

It would be wise to save money if you have that much money. Keep thinking that way you'll run out soon, you would be able to get more than 300hp for 27k worth of upgrades if you did it yourself.

and here i could add 150hp to it for under 4 grand...

people with money, they just don't make sense sometimes.

Welcome to the world of Mercedes. I've had more Mercs then I can shake a stick at, and every time I think about modifying anything on one of them, I come back down to earth an realize any tuning house worth a damn will charge me like 50% of the car's value just for a shift knob. Kind of kidding, but not really. A tuning package for my old E320 cost $10k from Carlsson for exhaust, intake and a chip.

O, I agree with you on that, but working with rich people, they don't care.

To them, they can make that much back in no time.
