    • Unitronic tuned Audi 8V RS3 with TTE700 2.5 TFSI turbo upgrade vs. DME Tuning McLaren 570S

      A McLaren 570S is a fast car stock. A really fast car stock. For an RS3 to beat a factory example is impressive enough but a tuned example? Wow. These races are also from a roll and on the highway so it is not traction getting the victory.


      The RS3 is tuned by Unitronic and has a TTE700 turbo upgrade. The McLaren 570S has downpipes and a DME Tuning ECU tune.

      There are three runs but in all fairness the RS3 jumps each race. It cheats. It is no fun to run against people like that and the 570S driver should have adjusted to his competitor or simply jumped himself.

      The first run is a total beatdown.

      The second run is a closer start but the RS3 again wins easily.

      For the third run the 570S Spider opens the top for some reason. Maybe to look cool while losing? The honks are off with one honk coming then a pause then a second and quick third which the Audi goes on.

      Even with the jumping and poor 570S reaction time the RS3 still pulls a tuned 570S on the highway multiple times and that is quite the feat.

        The owner made it seem like less is done to the RS3 than there really is.

        TCU tuning as well.

        4sure built motor is needed to exploit this TTE upgrade, impressive price point though as the mclaren is 3-4 times the $$$

        The McLaren isn't supposed to be a value though and if it upgrades the turbos...

        Plenty of stock block/hybrid turbo cars have gone 145+mph. I don't see why it would be that far fetched on a stock block car.

        I have a McLaren 570 with catless downpipes and a Stage 2 DME tune. I also have an Audi TTRS with an IMS850 turbo on a stock block running E85. The McLaren is fast but my Audi is significantly faster.

        4sure, 720s run 8s with upgraded turbos, currently out of reach for a stock motor rs3/ttrs

        This is some classic internet car arguing here... We've gone from Car A vs. a 570 with bolt ons to Car A vs a car in a whole other league of performance and upgraded turbos. If Car A ever proves to be faster than either of the cars above do we move along to 'my uncle's 6-second Fox body' or 'my neighbors 7-second civic'?

        ... built motor really only involves drop in rods and pistons on the 2.5tfsi.

        RS3 hit 8s before the 720s.

        I think built motor is more than fair on a car that starts life as 350awhp and goes to 900plus.

        Its not built from the factory for 700rwhp like the 720s is and adding less than 50% increase to get to 1000rwhp. The RS3 is damn near 300% over stock.

        Don't get me started on 1 turbo vs 2, 2.5L vs 4L. The RS3 is a monster and beefing up the engine to handle the power is more than fair.

        It's got stock heads, stock manifold, stock crank, stock block. It's hardly built.

        I don't think it is far fetched but a built motor car obviously can take more boost.

        The owner just misrepresented what is done to his car essentially implying less is done to it than there is.

        The 2.5 TFSI has been around forever and is way cheaper. Audi probably sells more of them a month than McLaren sells 720's in a year.

        People are going way off track here an misunderstanding the point. The owner sandbagged the mods.

        If you want to build your 2.5 TFSI to take down McLarens, go right ahead. Nothing wrong with that.

        v8s have been around forever. The new all aluminum 2.5 tfsi besides 5 cylinders shares nothing with the old motors.

        So? Each V8 is different. Just because you can turbo one or tune one doesn't mean they are all the same.

        Yes it does. The block material changed but the dimensions, layout, bore x stroke, etc., are all the same.

        Huh weird can't find any 8 second 2.5 Audi's prior to this current model. McLaren's 4.0 in the 720s shares 40% of its parts with the prior 4.0 so it's not completely new either.

        This doesn't get anywhere. Unless the head or displacement is touched it's not adding power it's merely allowing the engine to hold the power. Sandbagging or not his car isn't the most powerful version out there

        Rs3 for sure jumped both runs but would have still won the races if they took of at the same time IMO. Impressive kill for sure
