Well said.

Once again, that 'well set up' car that you spoke of above can also launch pretty damn well on the street with the right driver behind the wheel. Maybe not quite as planted as it would on a prepped drag strip but on the right tire a skilled driver can still get it out of the hole pretty well.

On the street you tend to have roll-on races and the car with the higher mph (most power:weight ratio)will win 90% of the time.
and it depends on what starting speed and how far, who has the most nerve, and the lighter car

Default A little story.

(A)WS6 with bolt ons,gears,cam, and spraying 100 shot trapped 127@1/4.

(B)Another Trans am with bolt ons,heads,cam,and 100shot raced (A)WS6 from a roll and beat him by a couple of lenghts.

Both Trans ams are manual's.

My car at the time did trap 125mph. I was an auto. I raced (B) Trans am two time from a roll of 40-130mph on a privite road. This trans sprayed me both times and I won both times.

Now why didn't the car that that trapped over 127mph win against me? The reason I say over 127mph is because I seen the video of these two trans ams running eachother. I also seen the timeslip of trans(A) trapping 127mph.


I believe that trap speed doesn't tell the whole story, unless the trap speed is say 10mph faster than the other. Spinning seems to inflat trap speed for manuals.


Hopefully this isn't confusing, had to type this up fast, just got home from work. If you have any questions about what I posted, feel free to hammer away.

Absolutely.
There is no guarantee that a car trapping 120mph will beat a car trapping only 118mph even from a roll...if the car trapping 120 spun it's way to a 1.70 sixty foot while the 118mph car was hooking 1.60s and still trapping that high then it could very well be the quicker (or at least equal) car from a roll.
Now if the 120mph car were to suddenly find traction from a dig then his sixty foot and ET could of course come down but potentially so would his trap speed (maybe 119/high 118s?) as well.

Fair enough, more power is always a good thing as even the worst driver can still improve...but some people might be more interested in/impressed by that human element that makes a particular combination, any combination, simply run quicker.
Adding power is fun and there is a right way/wrong way to tune a car after adding said power but not everyone can be trained to extract the most out of it either.
A great driver in a 400rwhp manual Corvette can still beat a poor driver in a 450rwhp manual Corvette, all else being equal. And if that's the case, what's the use in having more power?
Traction comes into play here too of course.

Going back to the original question of which is more impressive, it must be first understood to whom.

To 99% of the population who ask "How fast is it?", the expected response is MPH, simply because they don't comprehend ET.

To the remaining 1% who understand drag racing, they expect to hear ET and MPH.

If you ask me, I'll say reaction time trumps them both.

This is a trick question, but in most instances I am more impressed with MPH than ET. In the end I impressed with car and the power not so much the driver, sticky tires, auto, or drag suspension.

It's all a personal preference we are all different.

LOL... I had this big long thing typed up and I decided I don't care. This debate will never stop. I like both MPH and ET haha, I will prefer more MPH rather than picking up better gearing to for better ET. And I think when I go with a supercharger that'll be important that I'm on the stock non-z51 gears. So its all your personal preference and no one should put someone else down because of it =P

Put some gears in that car.

Oh wait, that's an arguement for a different thread.

Does spinning the tires really inflate your trap speed? I have heard that before but it makes no sense to me.. Can anyone show me some proof that it is true?

It can yes. but only up to a certain point, too much spinning can actually lower one's trap speed as well.
Think of it in terms of distance traveled. Generally speaking at wide open throttle a vehicle will trap higher at the 1340 foot mark then it did at the 1320 foot mark. Spinning one's wheels at the line instead of dead hooking (dead hooking is better for sixty foot and ET almost every time of course) essentially allows the car to gain a little more momentum so to speak, to basically travel further than 1320 feet by the time it hits the 1320 foot mark.
Or something like that LOL.
There is no actual proof or data to back most of that up but it has been shown to be true by numerous drag racers on many occasions.

What was the difference in DA when you ran and they ran? Were wheel and tire setups the same? I ask because I have not come across a scenario like that in my experience.

To me ET is more impressive and have seen where it's not always with the fastest mph, but have never really understood why. What you described kind of makes sense only if spinning out of the hole, if you spin some down track then you loose mph, agreed?

when your getting pulled on the street/open highway. The fast ET is mostly all 60ft.
600 to the wheels with stick is gunna pull away fast from 400 hp with an auto!

I really never get this argument.

Two cars are on a track. Car 1 runs a 10.61 at 125 and car two runs a 11.8 at 138 (I saw a twin turbo car on this board run exactly that).

At no point in this race would the 138mph car ever be in front. At the 60' mark, the turbo car ran a 2.1 and the 10.61 car ran a 1.4? Its ahead at the launch and car 1 also crosses the finish line a full second sooner.

If the race had taken place on the street, the slower trapping car would always appear to be 'pulling' on car 2 all the way to 125. So what does the guy do in the car thats trailing, call car 1 on the cell phone and ask what his speedometer says? At the 125mph point on the street, car 1 is pretty far in front.....he pulled car 2 the whole way.

But I know, I know, you keep racing until car 2 wins and then its a fair race.....the longer it is. So only 50-150 is fair and not 0-125. Its kind of silly if car 2 goes nowhere and hits 138 while car 1 is way in front and didnt hit 138 yet but he is still in front.

I'm glad I have ET streets and FI.....Oh wait then there is the driver and I'm not so good at shifting.
