    • An APR tuned Audi S8 on race gas versus a stock Cadillac CTS-V on the drag strip

      This is a bit of a mismatch on paper especially considering just how potent APR has shown the Audi S8 to be with their ECU tune on 100+ octane race gas. Over 600 horsepower at the wheels tune only on race gas is no joke. Already breaking into the 10's tune only is also not a joke. The CTS-V certainly is a potent sedan with a supercharged 6.2 liter LSA V8 but being stock and at 556 horsepower to the crank it is in a bit over its head.

      The drag races in the video below between the two bear that out. The S8 simply rips the CTS-V out of the hole on its way to an 11.25@123 1/4 mile pass versus the 13.47@111 for the CTS-V. The CTS-V did do better in subsequent runs getting into the 12's with a 12.7@114 but the S8 still beat it down without breaking a sweat.

      Keep in mind this is a Flordia drag strip so the times will be a little slower than reached in other areas of the country.

        lol PBIR is not a slow track (track elevation there is under 30ft)...countless records are set on that track because of how good the conditions are there (I've lived up the street from that track for years when it was called Moroso)

        Nobody called it slow but the times are slower than those set with these two cars in other places. It isn't one of the faster tracks in the country.

        ok bud...lol you don't even know what PBIR looks like man much less driven on it. The track is under 30ft of elevation AND newly renovated and prepped better than any other track in Florida

        Don't sit here and tell me what is what. Is PBIR as fast as MIR in the winter? No. So what are you babbling about?

        Florida weather is warmer. I'm not calling PBIR a slow track that is something you apparently misconstrued but I consistently see quicker numbers elsewhere not that one can not run quickly in Florida. Have CTS-V's run faster than this? Yes. Have S8's? Yes. There you go.

        Yea...they've also run faster than that on that same track. See magazine/forum racing and actual real world results aren't always the same. Taking a couple Hero runs and comparing it to an average run of these cars at PBIR doesn't mean the track is slower. But you know everything man (seemingly omnipresent from Cali to Florida...impressive)

        So you understand conditions matter? And that weather has an impact? And other tracks see far more negative DA? Wonderful thanks for much for your time.

        I know enough to realize mentioning the track is important for context and that there ARE faster tracks which does not equate to PBIR being some horrible black hole.

        PBIR = Much slower than MIR, Atco, Sacramento etc. in their prime conditions. It's called humidity. When the car sucks up water it goes slower. A CTS-V coupe E.T record was set there, but the trap speed was 2mph slower then other stock cars at faster tracks. On a 40 degree night with low humidity (if you can catch it), it could hold up to the nation's faster tracks but those conditions are matched or beat @ nearly every opening night at Northern tracks in drier climates

        My car has no MAF, it's basically open stacks. It's ultra sensitive to D.A. When I go from Baton Rouge (sea level) to Atlanta (600-1200ft) it's noticeable faster solely because of the decreased humidity. The humid/warmer air of a sea-level or below seat level/coastal environment works against my car far more than the increased altitude and drier air on the piedmont in Atlanta.
