Thanks everyone for the discussion and information, exactly what I was looking for (both sides of the coin). I know when I switched from my hybrid to my current road bike my average speed went from ~14mph to ~18mph, so I was just curious what everyone's personal experience was.

A coach sent a rider up the Alpe d'Huez (8.6 miles, avg grade 8.1%, max grade 13%, one of the toughest climbs in pro cycling) multiple times, asked him to keep his power constant, and measured the times. Without extra weight, it took 49' 40". With 4 pounds added only to the frame, 51' 40'. With 4 pounds added only to the tires, 52' 01".
So are these time savings this significant? If you're being timed in competition, then yes.
So are these time savings this significant? If you're being timed in competition, then yes.
Anyway, I'd been stuck in the top 11% of that climb for nearly a year, and was taking a few seconds off every month or two, but the progress was slow. I bought a lighter bike, and first ride up I moved up 50 places or so and was in the top 10% finally. Point is, "timed competition" can mean a lot of things to a lot of people. I'm in timed competitions with myself half the time I'm on my bike, and I suspect many others are too. They are relevant to me, and only me. $2500 well spent in my book.

Studies have already shown that on flat or downhill, doesn't matter what bike you have. On hills also indicates you won't be able to truly benefit from a lighter, stiffer, etc bike unless you are fit/light and damn good cyclists. At slow speeds, doesn't matter what bike you are riding, could ride a 25 lb bike and be just as fast, cause you suck on hills. I'd imagine 90% of cyclists out their suck on hills and wouldn't truly take advantage of the lightness and whatever else makes awesome about their bike.
Personally in this thread, would only take the comfort, feeling good about yourself, feeling more motivated etc seriously, rest is probably hogwash. There just aren't that many racers and bikers good enough to quantitatively gain improvements from bikes. Just saying, 90% of cyclists I see are either old, slow or fatties. Most of them fatties. I think I'm fat, but they put me to shame in fatness.
Anyone else notice fatties really take pride in their fat rolls? Wearing these super tight bike clothes, you can't miss a single roll of fat, dimples and cellulite. Just saying, before I put on any aero, form fitting bike clothes, I'm going to lose another 15lbs. Made some gains weight loss this week!

Best money I ever spent. I accelerated like the third stage of the space shuttle booster rocket. I climbed like a rhesus monkey with a roman candle stuck up it's rear. I braked like a porsche with 22 inch brembo disks. I saw unicorns and rainbows every time I turned my head. Women threw their bras and panties at me as I rode by.
Thanks for asking.

One thing that will make you faster and is more important than a few pounds is a good pro fitting. Made a huge difference for me.

He should run out and buy a $10,000 Storck or Parlee. Fitness and form is not what makes you faster, it's the pricetag!

In an extreme case of upgrade, yes there can be a measureable difference. I upgraded from a '75 steel 10 sp, 28 lbs to 21 lb alu/carbon/105 (triple front chainring) and the first time on the new bike I actually made it up one of the hills in our neighborhood. So yes, quantifiable - Hill or No Hill.
Another example is 30 mile flat bike path, zero increase in average speed. So again, quantifiable - no improvement.

I think as others have said; the gains you'll get from a new bike will be marginal, unless you really do go from a very bad bike to a very good one... if you go from a reasonable bike to a very good one, you might see a little increase in speed. Below is a chart created from some testing I did using a Powertap, a nice flat road, and a day with no wind.... this is pretty much the biggest "upgrade" you can make; lower riding position.... At an output of 250watts my speed went up by about 2.5mph... this improvement was "free".
Of course, if you're already in the low position then you basically have two options; marginal gains from a slightly better bike/components, or training....

simply put, IME, a 25lb bike is a hindrance as far as performance goes. i'd get a lighter one.
a recent purchase of a very inexpensive aluminum Performance Bike frame and a mix of oldschool parts and a DIY wheel build resulted in a 15 lb bike for about 600. it could have been less if i hadn't splurged on a NOS Campy Athena crank and brake.

Some folks say, "Without a photo, it didn't happen!" I personally find that attitude insulting, but I have to say a photo with the bike and a scale readout and a parts list would shut me up in this case.

Maybe 15 lbs and 60 oz?

OP,
I have a powermeter and I've found this calculator to be incredibly accurate. So, if you have a hill around you where you have a good idea of the percent grade, you could try different bike weights and see how the speed varies at the same power output.
You'll also see that bike weight makes very little difference on the flats.

OP, unfortunately I can't give you quantitative measurements, so feel free to ignore this But here's what I've experienced, Litespeed vs. Wilier:
The difference in frame stiffness is significant between the two, the Wilier responds IMMEDIATELY. But the difference is more apparent at large power levels - when spinning, it seems to largely disappear.
The Wilier is more comfortable on rough roads, and the Litespeed with carbon fork is pretty good at that.
Cheers
- In the saddle, not climbing, relatively little difference (possible none)
- Out of the saddle, high power (flat) - faster acceleration and terminal velocity on the Wilier
- Out of the saddle, climbing - faster speed on the Wilier

You're going to get a lot of "great" answers to this question... :-) hahaha. But I can give you my experience from equipment upgrades from my entry level aluminum, to entry level carbon, to upgraded carbon, and finally upgrade wheels over a 4 week time period.
10 mile square loop by my house... no stop lights... It was almost my daily ride.
After a year of riding a 20lb aluminum bike - I was at 18.15 mph avg as my best route time. Bought an entry level carbon, next ride was fastest ever at 18.56mph.... started racing the next week, decided to upgrade immediately and went from a Trek Madone 3.1 to 5.2 and immediately the next ride was 19.25mph, the next week I got upgraded wheels around 1500 grams, dropped a pound in wheel weight and rode my 10 mile loop under 30:00 for the first time ever at 20.05 mph.
So I road this loop for 6 months...and went from a 17.5 to 18.15mph...just gains from riding... dropped the bike and wheel weight, added stiffness, and a little aero etc... and gained almost 2 mph in 4 weeks.
After gaining almost 2 mph in equipment... the gains then were much slower over the next year from strictly training...but got it up to about 21.5mph.
going from an aluminum 20lb bike to a very good racing bike with racing wheels at 16lbs was a huge difference to me. Someone above mentions ~4 minutes over a 33 minute ride... That's about what I experienced as well going from entry level aluminum to racing carbon. YOUR MILEAGE MAY VARY
