Has Anyone Done This??/ '01 v.s. '02

[ZO6LS6]

Done a side by side run, to see how much quicker the '02's are, compared to the '01's??
If so, what was the results............
Secondly, if you have OWNED both, and have times on them, this would probably be as close as we can get........
Just curious...........

[WA 2 FST]

Still trying to justify a reason to trade the '01 in on an '02, huh?

I really wish I had my car, so we could test this ourselves!

Have a great holiday, Z06LS6.

Both used slicks. Ranger has a 2001 with just the Halltech TRIC, but other than the intake, is bone stock.

J-Rod has an 2002 bone stock except for slicks. Both had fairly close 60' times.

The comparison:

2001

Ranger with the TRIC - 11.94 @ 116.65 MPH- Factory 385 HP-Computed HP=408.8 HP* Dynoed 345 RWHP or 405.88 HP.
The TRIC added 23.8 HP bringing it past the 2002's terminal speed.

J-Rod bone Stock - 11.96 @ 113.52 MPH-Factory HP 405




The terminal speed is an indicator of the HP.

Ranger actually has over 3 mph more than the stock 2002 even though the 2002 claims +20 over the 2001. It takes 41.8 HP to gain 3 mph in the 1/4 mile.

* See Calculator section at www.CorvetteC5.com

Tom Easterday did an experiment last year with his 2001 Z06, running it before and after the TRIC. His best run stock was 12.71 @ 113.8. Best with the TRIC was 12.40 @ 116.

This year the average MPH with the T-1 and TRIC have jumped to 118 to 121 MPH.

The factory quoted 12.6 @ 114 MPH for the 2001 Z06 and 12.4 @ 116 MPH for the 2002.

J-Rod. I need to get you behind our 2002 soon! Excellent 60' et and run!

I'll say it again, Gentlemen.

If you don't correct the ETs & mph to Std Day conditions using the SAE HP correction factor computed from the weather conditions of the run, comparisons are meaningless.

[ZO6LS6]

I agree.................

But, this is probably AS close as an answer as I'll get........

And, to be REALLY realistic, you would have to have the SAME drivers, doing the same 2 cars, same day, one run, RIGHT after the other.

Ranger is runing on drag radials not slicks, and J-Rod is on ET Streets a dot approved tire but closer to a slick. As Roger stated there is much to analize between the two but your not even close to a logical asumption.
Z06LS6, With the imformation available to us right now I have seen 01's run 114-6 stock and 02 run 116-8 with no air box, if you extrapolate an et differance I think .2-.4 posible improvement with the 02. Ric

MARKETING! Is that what I keep hearing? I thought it was just ...


The model shows a 0.26 sec ET advantage to the '02.

I can compair for you:

Three months ago I had a 01 zo6 for nine weeks the mods are as follows TTS 1.58 long tube headers, Halltech bottom breather, underdrive pully, and x pipe. The 01 ran the following times

12.396 at 114.51 mph
12.4.57 at 115.39 mph

Now I have an 02 with the same mods and the times are posted on this link "with and without nitrous"
http://www.opticwebsolutions.com/ssm/index.html

11.936 at 119.mph

My 02 with the same mods is quicker and faster in the 1/4 mile. If you are thinking of getting a zo6 get the 02 but they are both great cars.

Merry Christmas

Let's see. That would make the only difference the cam:
The 2001 Z cam is 0.525/0.525 204/211.
The 2002 Z cam is 0.551/0.547 204/211.

So, for ~ 0.025 in lift the new car is ~ 0.5 sec faster?
WOW!

I suspect there was a big difference in air density between the runs.

It is strange there was no real difference in the runs with the air density, the 02 computer is a strange beat. On the wideband on the dyno this car do 11.0 on pass then up to 12.4 the other changing the RWHP big time I have seen as much as 19 RWHP change on the same dyno day, this car runs FAT that is for sure.

This is just a holiday suggestion..

if track runs are bullsh-t and dyno runs are bullsh-t..ie. comparisons between the 01 and 2001 Z06's for which this post is about.

What do you people who dislike this guy Jim Hall and his posts want to talk about in a Corvette ZO6 site..?

Performance of the '01 and '02 Z06 were the subject. I think a typo sneaked in with the flames. Intelligence is not in question - science is.

My years of experience around after-market suppliers is that they are making a living selling stuff. They will generally sell you anything they can – if you need it or not.

Evaluating any performance change without including the science that applies is simply marketing. Atmospheric changes affect air breathing engine performance – simple as that! I would venture to say all pro race teams and most sportsman teams track weather data. They know how important it is.

Check out the dyno data in this post:

Well having seen both on a dyno same day same mods and stock 9-13rwhp is what we saw.
Usually all after 4,500 rpm and only 5 rwhp below about 5,500rpm
Folks a small increase in lift combined with two less cats and no air screen does make a difference but nothing you can't duplicate yourself. And most of gain is way top end so unless your racing.
I road race so to me the biggest change was brake pads,shock valving, and 12 pounds less weight.
The difference in price could buy the parts to change this easy.

I do agree with above though. Drag strip is to many variables (driver, condition) even on the same day.

I assume no re-learn was done. Has anyone done a base dyno, then an intake change only dyno, then a re-learn (~100 miles) and another dyno. I think that some of the HP increase noticed on the post mod pull will go away after the PCM re-learns the LTFT.

professionals..who care and think they ... are experts in their field of science..can try and find a fault in a situation by utilizing some degree of logic..to just deny positive results..time and time again...

In fact..the utilization of logic to maintain the status quo..is the irony.


Change is tough..Change is uncomfortable..

Stay stock ..its better for you.

Its ok...
