SlrPower

I have heard that when you put aftermarket wheels on an SLR it voids the factory warranty. Is this true? Are there any mods for the SLR that will keep the full factory warranty? For example like how bmw had Dinan which keeps full warranty.

Thanks alot

This topic has been beaten to death. by definition NO aftermarket mod can void your warranty unless the manufacturer can PROVE that it was that part that caused the failure. A famous supreme court case "Magnusson vs. Moss Warranty Act" set a court precedent that the burden of proof is placed on teh manufacturer so unless your wheel fails at 200mph or something, theres no way they can blame you. Same is true for intake, exhaust & etc.

There aren't many mods out for SLR other than pulleys and a few other small things.

How about some pics of that SLR?

Give Renntech a call. They have an upgrade package for the SLR that bumps it up to 722bhp.

Maybe Renntech should post up a dyno chart showing their 722 package?

This is our Evotech Stage 3 SLR

McLaren and RENNtech

Car done in US, dyno'd with 93 octane not 98 as in Europe, rear wheel power

The dyno chart was done in Germany using 100 octane fuel, in the US we use 91 to 93.
At the wheels the car had 388.5 KW, to get HP, you need to multiply this by 1.34 which would be 520.59 HP at the wheels. Their dyno calculated 725 PS at the crankshaft which in HP would be 714. Also shown is a power train loss of 131.5 KW or 176.21 HP, that seems a little high (24%). Renntech uses only a 20%. Also factored in is a torque converter loss of 2.5%, the SLR has an electronic locking torque converter so their should be no loss

RENNtech gets 580.48 HP and 586.69 torque at the wheel.

Here is our dyno chart.

Hi The Car was made for 96 octane fuel not 100 octane but the drivetrainloss is measured !!!! that mean you have much less HP ........or you use our old Software ? with 100 octane we made easy 750 hp on the Crank ......

Bigbob

520 Hp at the wheels is a good stock SLR.

Your graph shows (radleistung) 388.5 KW at the wheels which is 520 HP

Bob,

That's a Renntech dyno chart? Ok, how about some videos of a SLR being dyno-ed in your premise?

And even if that dyno chart is "acceptable", may i remind you who tuned that SLR for Renntech.

In case you have forgotten, according to this Car & Driver, your 2003 S600 was tuned by US
