How come all these badas dyno numbers and no track times? I see all of you guys building some cars putting killer numbers down on the rollers, but few are taking these things to the track and showing some slips <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
We put Mooses car together and with 429 rwhp it went 11.0 at 126. Im seeing more and more 440-460 hp heads and cam cars so you guys should be edging near 130 traps right <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Re: How come all these badas dyno numbers and no track times? dont get this started,i beleive dyno numbers and track times should not be in the same conversation... <img border="0" alt="[devil]" title="" src="graemlins/gr_devil.gif" />

Re: How come all these badas dyno numbers and no track times? why shouldnt dyno numbers be in the same topic as track times, what good is it if a car makes 455 rwhp at 7 thousand rpm but only make 200rwhp at 5000 rpm, if yo cant get the power to the ground at reasonable rpms then what good is the dyno sheet, the car is raced at the track not on the dyno

Re: How come all these badas dyno numbers and no track times? In time they will come. How do you expect a car that was just finished today to post track times today? Patience..
I was planing on going to the track Sunday but my clutch is on it's way out. <img border="0" title="" alt="[Sad]" src="gr_sad.gif" /> Just give us some time to work the issues out and we will give you some track times. A trip to the track is 260miles so it's not like I have then time to go everyweek.

Re: How come all these badas dyno numbers and no track times? I agree with Grannyshifting, it is more helpfull to all of us to see track times to determine effectivness of mods than dyno readings alone.
whenever possible people should post both. Vince and i have talked about this before, "A Dyno hero can easily be a track Zero!" <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Re: How come all these badas dyno numbers and no track times? It took me about 4 months to get all of the necessary track stuff ready after I got my car "performance enhanced." Cage, axle, harness, suspension, all take time.
Having said that, I agree. Dyno numbers are nice, but let's see timeslips (with raceweight, DA, and all the other important info also) to go with it.

Re: How come all these badas dyno numbers and no track times? Dyno's take an engine to be setup properly. They show the results of the mods.
Track times require the car to be setup properly, the track to be prepped, the weather to not suck, weight to be removed, the driver has to want to beat on his car risking breaking drivetrain components, etc.
Thats why you see dyno results but not as many track results. Not everybody cares at all how long it takes to go 1320 feet from a stop.

I just can't agree with you on that one:

I think that most people want high dyno numbers so they WILL be able to go down the 1320 quicker than the next guy. Whether they get to the track much or not, it all boils down to the ability of there car to quickly clean up the 1/4 mile.

Re: How come all these badas dyno numbers and no track times? Here's the reason track times are important to me...99% of most cars time is on the street. Track times are much more indicative of what a car can do on the street. Sure, the tires are different as well as a few other things for some cars, but the load, suspension, driving techniques, and general dynamics of the car are very similar. Dyno's, on the other hand, don't reproduce that. I have seen MANY high dyno hp cars turn average times at the track.
Dynos are a tuning tool. Not a performance guage.

Re: How come all these badas dyno numbers and no track times? My car dynos damn good but has Zero suspension work or weight reduction other than the spare. I wanted to get the motor fun to drive on the street first. now I have to learn how to get it to hook from a dig. You alreaded bested my time and I have 140 more hp than you.....priorities I guess.

Re: How come all these badas dyno numbers and no track times? I agree a dyno is a tuning tool..
Sure I like to see big dyno numbers but I dont get caught up into thinking dyno # = KILLER ET's.
As a matter of fact,I'm redynoing my car on Wed.
I changed headers,verter and havent redynoed the car since the 12-bolt went in a few months ago.
Just wanna tweek the tune w/the WB to make sure everything is okay and then its off to ATCO on Thursday..

Re: How come all these badas dyno numbers and no track times? Put it this way.. If your car dyno's well. You know that you have the capability to run the times that you see on this board with a similar track setup. You also have to take into consideration we do not all drive a like.. Some are better at racing than others.. I have seen the owner of a car run low 12's all day. That owner let his friend drive the car who weighed about the same and his friend ran mid 11's in the same car on 3 passes.. I know for a fact I am not the best driver.. It took me months to run low 12's in a 11 sec car at 3750lbs and 3.42's on DR's.. One of our Ford guys gave me the best advice.. He told me if I want a 11 sec daily driver.. I should build a 10 sec track car.. What he meant by daily driver is street tires and stock weight.. The track prep is with reduced weight and sticky tires...

For example, there have been more than a few turbo Vipers putting down sick amounts of HP and torque on the Dyno. But why is it that 800 RWHP in these cars is only pulling mid-10s? Because the cars are hard to hook, hard to launch, and even harder to drive. Put the equivalent power in a well set up f-body, and you are in the low 9s.
Which goes to show that the car with the most power/torque is not always the *quickest* car, which is what matters in racing and on the street. Assuming OK aerodynamics and gearing, the car with the most HP (errr, best HP/weight) will always be the fatest car on top-end though.

Re: How come all these badas dyno numbers and no track times? I think the dyno is a gauge of performance gains due to modifications to the motor.
I think mph is a gauge of ET capabilities.
I also agree that some people just want to know what they gained performance wise due to mods. The track is not as accurate of a gauge for performance gains due to too many variables that can effect ET, therefore the dyno is a more reliable and accurate gauge IMO. If you only care about ETs, then I know a few people who never dyno and gauge their performance on ET gains alone. Because they race so much, they are more consistant than your average person who only goes to the track a couple of times a year vs a couple of time s a week.
Also, good ETs depend on good 60ft times and that requires hard launches which eliminate stock clutches, tires, and eventually rearends! <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> And good ETs also depend on lower race weights, which mean the car should go on a diet.
Not everyone is willing to or can afford to spend the extra money on clutches, tires, rims, rearends, etc. to drag race their daily driver and make it run low ETs. Nor are they willing to give up thier radio, air conditioning, seats, bumper reinforcements, etc. (creature comforts)to drop their cars race weight. So rwhp and torque versus ET is not as closely realted as people think. Less wieght = less power requirement for a lower ET, better traction = less power requirement for a low ET.
In conclusion, some of us just want a fast daily driver that is reliable and hasn't compromised its driveability for the sake of some low ET like some of the drag race nuts we all know. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> Just different goals and objectives, therfore drag race nuts should be objective enough to realize not everyone care about ETs. some people just want ot make thier car faster and how much faster is gauged by a dyno. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Re: How come all these badas dyno numbers and no track times? That is not always the case however. Somethign that shows a hp increase on the dyno can often lead to a slower (et AND mph wise) car that is not faster. You can go out on street tires on a 10 bolt an see how well your car mphs just as easy as you can strap it to a dyno. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Re: How come all these badas dyno numbers and no track times? I don't really think e.t. has anything to do with it. It is mph through the traps that is the best measuring device (considering cars of similiar gearing, race weight, and driver). If it was e.t. that was the absolute measure of power all a4s would be considered to have more then 50 hp on all m6s.

Re: How come all these badas dyno numbers and no track times? I had killer dyno numbers and killer track times with my heads/cam setup. It's going to take a couple months to sort my new setup out. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
