A time depends on many factors.

Depends on rollout.
No rollout is about 5.2s.
1ft of rollout is ~4.8s.
You can probably get it down to 4.6 with 18" of rollout, which is pretty much the max you're gonna get at any strip.

Rollout has a HUGE affect on acceleration times.
Adding a foot of rollout can cut half second off a quartermile ET.

Seriously?

Rollout is the measure of how far back from the start beam you stage your car before launching. What this does is allow your vehicle to get a running start before starting the ET timer. Using a lot of rollout is referred to as shallow staging. Using very little is reffered to as deep staging (because you are deep into the box formed between the staging beam and the start beam). The adverse affect of rollout is that the reaction timer starts the instant the light goes green, not the instant you cross the start beam. Therefore your reaction time becomes "worse", even though it didn't actually change.
The way you compensate for this is actually by sorta cheating.
It's hard to do, but what you do is stage shallow to get the ET advantage by giving your car that running start but you have to jump the light a tiny bit. This means that your RT will also decrease. The problem is if you jump too much you will redlight. The amount you can jump over your rollout is determined by the contact patch of your tire (that's the total amount of tire that contacts the road when your car is standing, which is affected by rolling diameter and tire pressure).

For street racing where there are no staging beams, you are essentially always starting with zero rollout, this is why alot of people dont bother talking about rollout. This is also why some people refuse to accept 0-60 times with rollout taken into account: because it's almost like cheating. But if it can be (and always is) done on a race track then you have to be aware of it and be prepared to use it.

This is why some magazines report 4.8s 0-60 and some report 5.2s 0-60.
The affect is equal on quarter mile ET. Dropping .4 seconds on your 0-60 by using rollout will drop about .4 second on your quartermile time. If you know drag racing you know .4 seconds is HUGE.

To get a 135 to drop half a second by power alone would take probably another 80 or 100 hp. Rollout is basically a free 100hp worth of dragtime IF you can do it right, which is not easy. I, for example, would fail miserably because Im simply not good at all at drag racing =P

Does anyone know any good 0-60mph websites. I'm curious to see where the 128 and 135 rank among other cars.

I like to use www.dragtimes.com

You can compare stock and modded cars.

I did mine (with chip and no other mods at the time) in 4.95s GPS verified. Oh and that was 0-61mph too.

There are other things that coming into play too, like how much heat is in the rear tires, air temp, road temp and road surface.

The road surface is probably the biggest of those factors. If the 0-60 run is done on old asphalt the small rocks could be coming loose and that would be like trying to launch on marbles. Or if they test on a drag strip with traction compound sprayed down and how far out they have it sprayed, it can be like having ungodly amount of grip, sometimes too much because it can bog the engine down.
