Of course, as you mentioned, forget the ET here, the trap speed is a better indicator of HP. So, again, even a properly running and driven 400whp car of that weight with that power curve should trap higher than 90mph. Yep.

I offered up my suggestions as to why it didn't in this thread and the other, according to the information posted. You are right, dyno numbers don't always translate into track times. A million variables come into play, but you can't flat-out say that a single given dyno, properly operating and operated, under the same conditions, is worthy of ignoring altogether. It is a good indicator of a given modification's increase in percentage of power, and then to back that up, they ran a stock LS3 Camaro at the same time.
I've been in this game for a while with multiple different types of cars and setups and speeds, on the streets, on the strips, and on the dynos, all over the country and in highly varying altitudes and conditions, I do have at least a little bit of a clue.

If you won't agree with or believe the above posted reasons for three slow 1/4 mile runs that I theorized about or came up with based on posts here or the previously posted excuses (valid or not), then are you saying that STS is flat out lying? Granted, I'm only going by what I've heard and read about STS, but from that I wouldn't think they'd go there. I admit openly that could be quite wrong.





(Oh, and yes he is making excuses, whether they are valid ones or not. )

Now to be completely honest, I don't him from Adam and I don't know the guys at STS (other than the sales rep I communicated with, sorta) so they could all be completely full of BS, this is the internet afterall, and I've been through that number too many times already.
I just kind of find it a hard pill to swallow that 6.5psi of boost out of a kit from a reputable vendor would just flat out make the car LOSE power unless some factor or a combination thereof was SERIOUSLY wrong with the way it ran vs. a fully optimized and driven setup, which is obviously the case. There were many excuses made, and if they're all valid, they make sense. The tune was one, and later claimed by AAC and STS both that the tune was further dialed in after that day.

You didn't answer my question...
Do you really think this car actually lost power with the STS kit on it? Seriously?

I'm with you on all the skepticism, and I'm not going to buy this kit (yet) either, but try to be as factual, mature, and unbiased as possible please. You have made lots of valid points, but try to take other educated comments into consideration as well.
We all want the same thing afterall... badarse spooling LLT Camaros.


Ok... I must apologize... I thought the "Seriously?" had a more of a sarcastic tone to it.... so my bad... sorry...

Couple of things... they tuned this car on a DynoJet, IIRC... which means the car didn't have a "REAL" load on it... My experience with DynoJet tuning is you use the DynoJet to get you close but then you always to some real "load" testing at the track (or the empty streets behind the shop... LOL). Found this time and time again... Car ran great on the dyno but then once on the street would ping like crazy, etc. So the final tune ended up being dialed back quite a bit from the dyno in some cases..

Could this have happened with the STS/AAC car... Certainly could have...

The real issue I have is we simply are not getting any kind of straight story what so ever... First it was the wheels, then the driver, then the tune, had to lift because it was lean.... No, STS, says the tune was spot on and Vince has has basically confirmed he has done no further tuning... so which is it?

Heck, I'm seeing some interesting things on my car right now... Makes me think perhaps the car does behave incredibly different on the dyno than it does on the street...
