    Timeslip. I'm 5911 btw.

    So yes, you nearly stayed with a 2012 Camaro RS. However, the timeslip tells more of the story - specifically the 60ft times and trap speeds. The fact that he didn't get off the line as well as you did (about 0.150sec slower 60ft time) means his ET is about 0.3sec slower than it would've been if he matched your 60ft time. (The general thumbrule on 60ft times is that a 1/10th improvement there will net you about double that on the top end.) And the fact that his trap speed is nearly 4mph faster than yours, despite being in a car that's a couple hundred pounds heavier, shows that the car is making quite a bit more power.

    Your keeping it that close just shows that you did a better job of driving than the Camaro driver did. And without having any sort of baseline it's impossible to say whether the Iceolator is providing improved performance vs. the Camaro. Had you had the car at the strip prior to the Iceolator? If so, what were your trap speeds? That's the best way to know if you're making more power - compare trap speeds.

    There are all sorts of online 1/4 mile calculators that you can play with. Using this one, assuming a "race weight" of ~3700#, your trap speed equates to 221rwhp. Then assuming about 18% drivetrain loss for a typical automatic, you're looking at about 270bhp - so 15bhp over stock. Of course, there are some pretty big assumptions in almost every step of the calculations, so that could be completely inaccurate.

    Edit: Not trying to rain on your parade, of course. It's cool you're getting the car out there, and as you said, it's a lot of fun when you can match up with your buddies. Just pointing out that even in relatively low power street cars, there's still driver skill involved that can have a big impact on how your performance compares to someone else's.

    Re: what performance parts would you use?

    True. Everything you said is valid. I wish I had been able to run on the track before the upgrades so I could tell.

    His car has never launched faster than mine, and I consistently beat him, even in rolling starts, until the top of 3rd/bottom of 4th gear. So maybe it made more of a torque gain than hp? Which would explain why it feels like it drops off alot in 4th gear. Also, on the dynosheet on Rx's site, it does show the biggest rpm increase (yes on DI, so maybe dif) in the middle and then a drop at the top end.

    None the less, and I have no way of validating this right now, but feels like a by far more increase than 15bhp. With the feel of my ass anyways.

    let it rain! haha. Maybe if we go again I'll swap him and run his while he runs mine..see if that'll make much of a difference.

    I may also have be a little excessive on my assumptions. If so, my ignorance. Hopefully I'll have a dynosheet by the end of January so I can get some specifics.
