Dennis, you are right, it's a mix. However, I do believe that people are dynoing their A4's with locked converters (and the A6 people can't do this yet). It's an old dyno trick that most of the Fbody guys have done in the past. Let's face it, if a stock A4 dynos at 350 rwhp, that's about the same as an M6 and that's just not possible without a locked converter. Or the dyno operator is playing games with the air temps.

But you and I both know, it doesn't mean anything to dyno higher than someone else. Line up next to the guy on the drag strip and see who wins. That's why we refer to it as a 1320 foot lie detector.

And sir, when it comes to the quarter mile, you are FAST and are still my hero. 11's in a daily driver is one of the most impressive things I've ever seen!

 

I'm pretty sure Vishnu did this on a dynojet - Vishnu got kicked out of their old shop a while ago so I assume they no longer use a DD dyno, but the one at Modacar down the street which is a jet.

 

Glenn you are right about the dyno tricks. i see it all the time the 1/4 is the real dyno. i see guys with 400 rwhp and i only have 376

 

It's a good thing we don't race dyno's. It's usually easier to achieve big results from little mods with power adder cars. I still have a hard time believing 100rwhp with just a tune without uping the boost in the turbos though. Of course I'm coming from supercharged cars, the 03 Cobra being one of them and I've never had a turbo car.

 

However, those A6 & A4 cars are putting down some nice numbers at the track too.

 

Sorry, didn't mean to make you so defensive. My base numbers were 334 rwhp 323 rwtq. So did you get your high dyno numbers with a locked converter? If they were done unlocked, then congratulations, you have a very strong car!

Also, I didn't notice any times or speeds in the 1/4 mile sticky? Are you telling me you haven't run your car yet? You don't want your car to become known as a Dyno Queen, do you?

My most recent numbers with headers are 360/360. Since I'm only 10 hp higher than yours, come over to Firebird and we'll run. Should be really close? Nothing like lining up side by side to settle a discussion. Should be fun.

 

hehe, my money is on you glenn.

 

Yea, you are liable to lose it all, be careful! I red light about half the time I run you!

 

Sure but I live in Cali, I'll run and beat you after my 3.90's go on next week

Yeah I see you say you're sorry for saying you'll "bury" us A4's at the track It's like you automaticaly (no pun intended) assume you've got the fastest Vette around now, cause a couple guys ran low 12's I saw plenty A6's in the 13.40's as well..

Same can be said for the A4, but I'm not on here telling everybody if you've got an A4 w/3.15 gears you're gonna run 12.50's all day long That's the BEST some did while stock, same w/A6 12.20

Far as I know they didn't lock my converter at A&A Corvette, I've ran other friends (M6 C6) verses/My C6 and been dead even w/them, this A4 C6 is stout & I love it. I almost bought the A6 but couldn't justify the extra money at the time, still would like paddle shifters though, and it obviously halls ***

 

not to hi jack this thread here, everyone know dennis runs one hell of time in A4. but 13.4 in c6 A6? and you don't think this is driver related, heat soak or high DA? next thing you want us to believe your a4 when stock it runs 12.2 also just like ls1lt1. even with 3.90 gear, stock converter and 350 rwhp, you will need a down hill / neg DA to run 12.2 with stock run flats. come back and tell us if you are even close. if both cars has the same mods, same track, same driver, a6 takes a4 anyday.

 

A4 with 3.90's will be fast, put a converter in it and it will be unbeatable. However, did you know that the A6 is 1.53 x 2.56 = 3.92 in third gear. So the A6 is geared just a tiny bit better than the A4 with 3.90's.

I don't think my car is the fastest because of what other's have run. I actually run my car. My car consistently runs in the mid 12's at 114+ in 2000 to 3000 foot density altitudes. You say you've seen A4's and A6's run at the drag strip, so I assume you've taken your car out. So what have you run? That's the quickest way to see if your dyno numbers are accurate. I'm betting A&A locks the converter.

The most accurate measurement is trap speed since ET depends so much on 60 foot time. With your 350 rwhp, you should be running around 116 to 117 on a standard sea level day. You should run around 113 and change with a 2500 DA.

You do not have much of a choice for race tracks in southern California: 1/8 at Irwindale, 1/4 at Fontana, 1/4 up at LA County. So, Phoenix is only 6 hours away, come over and lets have some fun.

And by the way, I didn't say I was sorry for saying an A6 would bury an A4, I said that I exaggerated. Also, without the gears I'm positive I'd beat you and your A4. And with your 3.90's I will still win but just barely, not because of the gearing, because of 10 more hp (or maybe even more if your converter was locked).

Looks like there very close...Why are you going to beat me again?

 

Had my C6 (auto-tranny) on a mustang dyno two days ago. My car has a hurricane air box, cat-back magnaflow exhaust and a predator tune.

To my disappointment, I only got 318 RWHP. The guy that did it, used the paddle shift in 3rd gear (I believe) for the test.

I cant remember the torque readings, I have the paper in the center console and my cars at the shop right now. Anyways, I just wanted to add my .02cents to this thread :-)

 

See if you can get the correction factors and look at noncorrected numbers. DynoJets like to take a lot away if the stack is cold. I've seen 20+ rwhp taken away on a cool (low 50's) dry day. Looking at your location my guess the dyno room was cold and it was correcting to it.

Sorry to put the thread back on point, you may go back to your childish thread jacking

 

Thank you for coming back to the issue at hand. I will see if there are any corrrection numbers.

 

The car will dyno slightly higher in 4th gear. Also, make sure your car is good and cool before the run. I lost 18 hp on a second run when I still had the stock thermostat. You could see that the ECM pulled timing at about 3200 rpm. Look for a dip in the torque which indicates pulled timing.

 

That run was with a density altitude of 2300 feet, it corrected to 12.2 at 117. I wish I lived next to those cold sea level tracks, that would be a blast. Anyway, at least I am on the 1/4 mile sticky. You need to quit street racing and take it out where it's legal. I'm serious, come out to Phoenix and let's have some fun. The problem with street racing (other than it's dangerous) is that you really don't prove a thing as far as how fast you are. A timeslip can be a sobering wake-up experience.

Also, just so you know, the 3.90's are a great mod, you'll pick up a lot at the track, however, you will dyno slightly lower. The higher ratio gear sets are less efficient. So now, you'll have to go out to the track to prove your car is fast.

I apologize if I hit a nerve with my statement about A4's, it was tongue in cheek. You obviously felt strongly about not being able to afford an A6.

 

That was most likey dyno-operator error.

 

If "the 1/4 is the real dyno", then could you imagine what Bonneville is?

 

Run him or me and find out
