    Unfortunately, but expectedly, most owners do not care about their real world performance, but just that they can brag to the guy next door that "my car makes xxx whp".

    Dyno warriors are prevalent throughout, and don't have the faintest understanding of how easy it is to manipulate a dyno number if one was so inclined. Because of this, atmospheric variables, intertia vs load dynos, calibrations, firmware, yada yada yada, I only look at trap speeds to gauge system performance, period. Dyno is a great tuning tool, nothing more.

    On the dyno where my car made 650, Kurt Robinson's car laid down 672whp with my exact setup (just on a different day). But, with all this meaningless our shop vs your shop crap, people will usually compare the low end of one, to the high end of the other, to suit their narrative.

    My car at 650whp, has been full weight--fully loaded GTS w AERO (ie. heaviest gen 5 you can buy)--on pump gas, 140mph in the quarter, and 168mph in the 1/2 mile, GPS confirmed. Not to mention, been around the country on a 2,000 mile road trip with 8hr track days, without a single issue.

    Its downright PERPLEXING to me, how there are shops claiming to have built dozens of these 700whp+ cars with ZERO results to show for them at the track. Very convenient.

    The dragstrip can be a good way to compare packages. MPH in the 1/4 mile pretty much tells the story.

    Many dyno's differ in the power they report. At one time we had 2 dyno's in the shop, a Dynojet and a Dynapack. One was for testing, one was for tuning. The Dynapack would allows read 15% higher.
    Most people use Dynojet numbers to compare as they seem to be the industry standard.

    It depends on how the dyno is calibrated as well. Some shops get higher numbers by calibrating the dyno to a higher than actual elevation. A one time, I think a shop in Texas had the dyno on top of Mt. Everest!

    I agree. We need more drag test comparisons. Right now VE has the proven themselves over and over. Geez your car went 140mph in the 1/4!?!?! That’s impressive.

    Be heavier if you got rid of them sidewinders
    When seconds count - lose a finger; it's extra weight! Who needs 10 anyway?

    140 in the quarter with 650 rwhp is amazing, well done!
