    Looking forward to it. Wish they would drop it in an even lighter car...
    Both trap and ET, IMO.

    Yeah, it would sick if the C63 had the M157. Actually, the SLK would be the most amazing application.

    Has an effect on both but I believe weight makes more of a difference in ET than trap while HP does the same but with the emphasis reversed.

    Nice times! Road & Track tested a 2012 CLS63 w/Performance package & did 12.0@122.5 on less humidity & colder weather. So now the RT tune alone it's doing almost 0.7 seconds faster in less than favorable conditions, this must be a much faster car in better weather. http://www.roadandtrack.com/tests/up...benz-cls63-amg

    I don't see any mention in the Road and Track article about the use of DR's so there is a difference in testing methods, and therefore, there wouldn't be a gap of .7 seconds if DR's were used in both tests.

    That's definetly a good question Sonny! But, who is driving an almost 4300lbs 2wd sedan 10's sec car on street tires really?

    I don't quite know the answer to your question. But, I would wager that the Renntech car wouldn't hit 11.3 ET on street tires.

    Very true! This would only be a high speed cruiser for the highway =)

    I guess Road and Track did.

    But, I've always wished that auto mags would test these cars with DR's. I agree with you, it's dumb to test the 1/4 mile times with street tires and not DR's.

    Although, I understand that often, the testing is not done on a prepped track; the testing is often done in areas that also have space for skidpad testing, which would necessitate the use of the stock rear tires.

    Trap would still differ and often street tires produce higher traps due to spin...

    Not really true, Insideline uses the Fontana strip when prepped for example. The local SoCal mags do the same thing often, including Road and Track.

    Of course trap would still differ if there was a power difference but I was responding to a post that mentioned ET--thus my mention of the effect DR's would have on ET.

    And although spin can help increase trap, it's not a bright line rule, as even in my own very limited drag racing experience, I have seen quicker 60' equate to higher traps than runs with slower 60' due to spin.

    And I get that you didn't state a brightline rule, you said "often."

    As I said, I was speaking about ET, because @m54b25 mentioned ET. I don't really understand the relevance of responding with "trap would still differ" other than you just want this to be a pure "Renntech rules" thread. Otherwise, you wouldn't have felt the need to "correct" my conception of comparing two cars that were run in the 1/4 mile; one with DR's one one without.

    Am I wrong?

    I have consistently seen higher traps with better 60's in my own drag racing experience with my E92 which I might as well call limited as well. With drag radials... street tires spinning produced higher traps on my E46's.

    My point is that street tires are often capable of higher traps due to poor 60 foots inflating them and that a higher trap with a better 60 means it is a far more sound representation. Obviously drag radials are used far more for ET than trap as the goal is the 60 foot.

    I love when I see people using the mention system! A great feature that people need to start using more. Planning on expanding it with a similar twitter style #topic system in real time.

    I'm not trying to make it an anything rules thread simply pointing out to you that the Renntech tune is making more power than even the PP as you can tell by the trap on drag radials vs. a trap on street tires which has a higher % chance of being inflated due to the propensity for a poorer 60 foot. I think this is a valid point, has nothing to do with any particular company.

    I would have felt the need to point this out no matter what.

    Lets see if the new TT can help stop the AMG depreciation demon . What the phrase ?" The only thing faster than a AMG is their depreciation . Hence why i chose a used car this time . A Lease does make sense though but it was out of my car allowance parameters . Click here to enlargeClick here to enlargeClick here to enlargeClick here to enlargeClick here to enlarge
