2001 faster than previous years?
I might be wrong here but I thought I read something saying that in 2001 corvette increased the horespower by 5 and the torque developed about 500 - 1000 rpm sooner! I also read that you could tell a major difference because of this.
I wanted to know your guys opinion. Compared to pre 2001 can you reall notice a difference in the years prior to 2001?

No you can't tell a difference.

Anyone that can feel in the seat of their pants a 5 hp difference from a 350 hp engine ... well ... they (or their pants) are full of poop and/or they just tooted.

Go to this link, scroll down about a third of the way, & you will see the faster 1/4 mile times for the 2001. http://www.corvettemuseum.com/specs/...erformance.htm
The 2001 A4 is 0.25 seconds faster & the MN6 0.15 seconds. The bigger factor was the increase in torque & the broader torque curve. You can improve performance by increasing the area under your torque curve. We actually lowered the peak TQ on our current engine, but have a relatively flat torque curve, & the car is much faster.
Also, the timing change in '01. By re-progamming the PCM you can pick up another 12-15 HP.
More importantly, there were numerous upgrades to the car, especially in Active Handling/Traction Control.

I think you would feel 25 lb ft of torque. Remember, torque is what gets you off the line - horsepower is what keeps you moving. 5hp is not significant enough to feel but the torque is what makes the slightly quicker quarter mile times.
Is it going to make a quick car faster, depends on the driver and the cars ability to "hook up" (get traction, etc.).
Also - 1/10 or 2/10 of second will win a timed race, but it isn't that big a deal.

Holy cow ... Great taste/Less filling -- Who Cares ... Big deal!! 5HP difference, are you all kidding me!?!? 
We all own Corvettes and are bicking about 5hp ... Come on. 5hp can be gained/lost just on Temperature changes alone.
A couple of mods later ... who even remembers those touque/hp differences?

With just a couple of mods, my 01 cranked out more rear wheel torque than a stock 02 Z06. Pre-2001 C5s with similar mods all had obviously-lower torque. If you can feel anything by Seat-Of-the-Pants, it'd be extra torque, not horsepower. 25 lbs-ft is enough to feel.

Yes you can. I drove 6 C5's all in the same day and ended up buying the 02 because it felt considerably stronger then the others which were all years 2000 or less.
Even the car sales man noticed it and commented on it.

It is the increase in torque that makes the difference here. This is one of the reasons I picked up my 01 (that and 2nd gen A/H). It is something that probably can't really be felt, but generally, the 01's seem a tenth or two faster in the 1/4 mile that the 97-00's. Not all, but most. Driver ability makes a huge difference too though.
