The video above shows a fantastic Switzer-prepared SLR McLaren coupe putting out 600 hp at the wheels - that's almost 750 hp at the crank!
This SLR makes use of RENNTECH's SLR PKG1 performance upgrades and the latest version of the RENNTECH's SLR McLaren software. Each SLR engine is assembled by hand at AMG, of course, and there are sometimes slight variances, but this is still a STRONG build - Switzer (our primary Ohio dealer) did a fantastic job getting the most out of this McLaren on pump gas (RENNTECH advertises 722 hp, or just under 580 hp at the wheels).
