Renntech 722 HP 722 SLR

In my new Luxury and Exotics magazine, they have a post on
Renntech developing a 722 hp version of the 722 SLR....

They have improved cooling and a pulley system that achieves this.

Anyone else heard of it?

The kit is aimed at the SLRs in general as the final result will be the same for both the SLR and the 722.
I have seen the dyno charts and the torque figures are very impressive

The mod-addicts with the 55 kompressors (mostly E55 guys) should really try to duplicate this setup and see where their cars differ from the SLR. From where, RennTech should be able to mod them to produce over 700hp.

I know there are a few guys that have put SLR cams in their cars and theres an SLR-type intercooler project going on.

We have an ECU/pulley kit for the SLR that is yielding 720hp.

As far as I know the kit consists of two bigger intercooler pump, one extra front heat exchanger, a bigger pulley 168 mm and software.
