A6 and Gear Ratio
TESTING INVOLVES ONE CAR WITH ONE CHANGE. TAKE THE SAME CAR AND DO A GEAR ONLY SWAP....THEN YOU HAVE PROOF.
Well see next week if the weather cooperates if I can get my STOCK HEADS,STOCK GEAR 2.56 with 3600 stall converter in the 10`s with a cam only with bolt ons.

We recently had lots of head/cam cars run different time at the track with the same peak power.
We are still looking at your proof that differently modded cars are all the basis for your proof.
I have lots of GEAR proof at tracks but you seem to think gears dont work on your car, yet you have not run a single car with only a gear swap as a comparison.

If people don`t agree with your opinions, you make jokes, but really the joke is on you.




Maybe we should meet in the middle....anyone for .15?

Its getting too aggressive. Good luck with the runs and when someone has more streamlines controled variable proof, Im open to hear it.
For a street car I would get a 2800 w/3.42's.

At least we all keep eachother in check!
The Best of Corvette for Corvette Enthusiasts





Make one or more runs as you normally would for the baseline.
Then make a run starting in 2nd gear instead of first.
Then try one by starting in 3rd gear. You'll need to slip the clutch to get started and not go WOT real early.
Then even try one in 4th gear only.
My guess is that the MPH will be nearly identical, but the ET will be seriously different.
That'd be a test of everything being identical except gearing.
I don't know if you could program an auto to do this, but if you could, then someone with a converter and someone without a converter would put this baby to bed once and for all.


Tony has timeslips, Ron Graham has timeslips, Mike has timeslips and I have timeslips to back up what we're saying. And what exactly have you offered up Spin? Apart from one or two mentions of ETs from other drivers (most of which weren't even Corvettes for that matter) and some lame rhetoric you haven't really given anybody here much of a reason to believe you and to use the phrase "controlled" and "drag racing" in the same paragraph (let alone even the same thread) is idiotic at best.
Anybody who's ever drag raced more than once knows that there is absolutely no such thing as a "controlled variable", so at best comparing similar cars with similar mods in similar conditions is the best that all someone can hope for and that's what I did in my other thread regarding this subject.
Wow, the next thing you're probably gonna tell me is that the SpinFast intake should be good for a full 3/10ths at the track....Oh wait, we've already been down this road before haven't we?
weather, so I'll give the full report on that claimed 3/10's from a no cam added car. So far from street testing/logging, it has not done much. It does sound a bit throatier than stock though with the hood up.

btw-it turns out that the 3/10's claimed down that road before was a Fast ported and installed by Cartek without a firewall mod.

I'll extend the same offer to you. If we colaborated and found the answer together then there would be no doubt if both sides had input as to controling the variables that can be controlled. My labor is free.
No need for personal attacks. I tried saying that to TonyB4 in a PM to make peace. In my defense I never got personal with these kinds of attacks because someone disagrees with me. I went back and saw the deterioration progression. You say 1 tenth and I say 2-3 at this power level and thats the basis for all this hostility? Agree to disagree. If there is a middle ground, its in the overlap of the two mods in question. Would gears alone get 3 tenths? If its 1.67 tenths are we both wrong? Its gone too far and you may want to look at the way the personal smacks increased as the thread went on because someone disagrees. While its obvious some people in this thread only respond that way, you and I dont usually do that so lets get it back to being civil.
I guess you all know I feel strongly about gears. I've driven the A6 with 3.42's and like them especially on the street. I was a track junkie for 20 years. I dont track a 50k car becuase I have hit the wall enough times to know its 'not worth it'. For this reason I dont do only 1/4 mile mods. My car is basically set up for the 1/4. The only change would be to swap my MT ET street 305/35/18's (everyday tire for me) for a 305/45/18 to allow up to a 140 trap speed and give me some side wall. The rest can take it....lev 4 trans, stage 3 diff, lots of power and a twin disc clutch. If it makes a car faster 0-60, 0-100 then I see it as important. Note I go from a dig. Knowing my mods you guess what it would do with a good driver which I am not.
I look forward to your new runs and seeing the results and how it plays into learning something. When I see something that proves me wrong, I admit it. I was wrong about L92 heads and admitted it. Can I be wrong? Yes. Maybe your next few runs will get me there. I hope that at least opens the door to respect.
Okie, I have 50 or so PM's from people seeking free info and 4 free e-mail tunes (friendship seeking gestures involving no money for me) to get to, including Siffert's tune above who is looking to discredit my intake manifold mods and porting. Feel the love.

a given track and a given date/time and applies the 4 components that make up DA (temp, altitude, barometer and humidity) and gives a scientific number for what has already occured. The fact that Drag Times DA (along with every other online web site and cable/TV broadcast weather) does not match to your "Atco Boys weather station"
does not mean it is inaccurate. 
it has to be done at the track surface, all the heat from some of the big tracks that have a 1/2 sq mile of asphalt generate a lot of heat, then wind speed is a factor, a fifth element. one day you will learn grasshopper, just admit it your wrong, busted

folks have run (save for some minor varience with altitude vs Google Earth). Except, quite oddly, for your deep negative DA track called Atco.
You cannot put a handheld weather station directly in the sun and/or clouds on the track surface, you will get incorrect readings all the time. For measuring track surface temp, you use an infra red temperature sensor. Every handheld weather station instruction manual will tell you to use that instrument in the shade ONLY.
For further details on how to use a handhled weather station correctly at the track, do contact Ranger. Basically he puts his Kestrel in an upside down 5 gallon bucket with the top cut off and out of direct sun shining down on it. Thus, it is now quite apparent why those Atco DA readings of yours are so out of whack with the rest of the world!

it's a 10.5" dual disc, haven't been able to get on it yet because i'm not tuned for the gear, plus they need to be heat cycled a couple of times
plan on hitting livernois this week for a tune,
i can tell you even though the highway is higher rpms, it's nothing compared to running 4.10's or 4.30's in my mustangs turning 2600-2700
just driving back from rpm yesterday, i was very happy with 6th gear now, before in 70 with 600rwhp the car was still a turd, now it accelerates nice
i personally don't think a big stall is needed with the gear, i pulled a 1.76 with 18" dr's at the track, with the 3.42, i figure 1.6's at least with a pretty much stock stall, maybe better, who knows
