    • APR releases their R8 4.2 FSI V8 Stage III+ TVS1740 supercharger system with a huge R8 tax - Overpriced at $23,749.99

      APR today officially released their Eaton TVS1740 based supercharger system for the R8 4.2 FSI V8. This is the same basic supercharger kit that they sell for the B7 RS4 at an arguably already overpriced $17,749.99. It has shown some excellent results on that exact same 4.2 liter FSI motor powering the RS4 to a 10.6 @ 130 1/4 mile (in a lightened car). One can expect similar results with the R8 but the question is, why the $23,749.99 price point?


      What is this magical difference that when using the exact same supercharger, exact same engine, exact same manifold, and similar tuning in the R8 that accounts for an extra $6000.00? Nothing. Not a damn thing except an R8 tax because the car is more expensive to begin with.

      The R8 kit due to utilizing so much of the same hardware should push the price down for both kits as it means APR is buying a larger volume of the same supercharger. They even use this same blower on the 3.0 V6 as an upgrade for the S4 so what in the world are you paying for other than blatant greed?

      APR's stuff is brilliant. Their tuning is awesome along with the reliability and this is a great kit. However, this is the same load of BS VF-Engineering pulled when they priced their R8 4.2 FSI supercharger kit at $25,000.00 when it used the same hardware as their RS4 kit (now seemingly abandoned) at $17,600.00. It's an artificial tax folks and we shouldn't put up with it.

      At this price point one can opt for a twin turbo kit from a couple of vendors that will offer greater power and torque for similar money. MRC Tuning holds the R8 V8 4.2 FSI record with their single turbo Garrett GT45 based kit that will no doubt outperform APR's offering which uses the Eaton TVS1740 simply to keep costs down between platforms as the RS4/RS5, S4/S5, and R8 now can all share the same blower.

      Dyno numbers, acceleration comparison, and video below. Yes it adds a good amount of power but APR is price gouging. People will pay it of course that is unless they are educated consumers.

        The R8 uses a different manifold design as well as two throttle bodies. There are quite a few differences with this kit so price must be based on lower volume, APR tax and R8 tax.

        You are right that it has twin throttle bodies but $24k is f'ing ridiculous when it's using an Eaton TVS and the same 4.2 V8 which means APR did not have to develop completely different software.

        Changing the manifold slightly for $6k? There is no reason it shouldn't be the same price and I could argue that R8 V8 owners are more inclined to modify than RS4 owners.

        Definitely a big APR and R8 tax.

        Different requirements for mounting the intercoolers and the rest of the kit too. Looks like they give you a vented fender liner as well. APR is an engineering firm, not a tuner. Either it required much more engineering work than it appears, and they're pricing it to maintain a small profit, or, like you say, they're trying to recoup investment on this and other projects more quickly with a larger margin. The market will determine if their pricing strategy is viable, and if there is a large margin, APR would be smart to reduce it to move more units.

        They have in-house tunes for their products.

        They make so much money they can keep this artificially inflated. With the turbo kits out for the R8 though I don't see why anyone would opt for this at this amount of $. If the SC was a great value that would be different.

        Right, but there are many so-called "tuners" who don't have the first idea about properly engineering a product, nor do they employ actual engineers. APR does it the right way, and it's expensive.

        But if they could move more units at a lower margin, there's no reason for them to not do so if it's economically feasible.

        Oh, I agree. If I had an R8 and this kind of money to blow on it, I'd definitely go the turbo route.

        I do not disagree their stuff practically has an OEM feel to it.

        If they have a higher margin on less units then... well. I don't know, we'd need their sales figures to figure this out but the R8 V8 has been out for a while and so have SC kits. They could price this $10k less than this, easily. The hardware used isn't $23k worth of SC kit that is for sure.

        If this was $15k which people think is insane for an SC kit already it would really be an awesome value alternative to the turbos. As it stands though...
