Houston - 10-11-2004

[RC45]

I spent last week and today taking care of some business that required a 110 mile commute - each way.

So I had no choice but to deplete some ozone, burn loads of fossil fuel and make good use of my Escort 8500 radar detector.. :twisted: - that allowed for 1 hour 30 minutes door to door... :)

Imageshack is busting my chops ... I frikkin cant see the image .... its not loading for me

[nthfinity]

lol, RC! good to see plenty of fuel in the car for the trip :)
i think the lowest ive averaged @ 112mph @12mpg over 94 miles via the escort 8500 (something ill never do again in the Jeep)

Works for me. :D

I would never dare go 100mph (~177kph) in Perth, not really willing to pay what would be a huge fine since the limit here is 100kmk. :?

[TT]

Uhm.. such speed remind me something happened to me well... less than 24 hours ago :(

[gis]

LOL 4.2 mpg,nice work RC,u could get through a full tank in no time then huh. :lol:

me and my friend achieved 106mpg the other day in his car :lol:

[DUNKiNUTS]

my truck will get 25 mpg at 85 so i think i would win. :wink:

[possessed_beaver]

fuck nice work mate,

burning all thoes fuels that america invaded iraq to get :P

[Anonymous]

hahaha, nice pic! You should get yourself a nice economical car like mine,cos i know what a tree hugger you are!!! :P ....... 44 mpg on the 200+ mile journey to uni :D

Get a radar detector TT :D

[TT]

Not allowed :P and I don't like to break the rules :D but, it would be like cheating IMO :D

if you dont like to break the rules ... how come they find you speeding ? :lol:

No idea... Shaggy would say "Wasn't me!" :D

The Escort 8500 saved me at least once per day over the weeek.. 3 times in one morning. :)

I use a relatively simple strategy - 5mph over on devided hiway (without a concrete deviding wall) with oncoming traffic and medium same direction traffic.

20mph over + on a devided hiway (with a concrete deviding wall) and medium same direction traffic - slowing down to pass same direciton traffic in case there is an unmarked car ahead... use semi-trucks and big SUV's as cover to run up on traffic.

120 to 140mph + on devided hiways (with concrete deviding walls) and light traffic.

Never crest a hill at more than 5mph over the limit... (you are easy prey for this one) - and use valleys/dips/bridges to cover running up to 140mph+ when in the radar "valley". :)

ALWAYS take note of radar blips - as they normally indicate a trooper working traffic ahead... the Escort 8500 picks signals up as far as 2 miles away... and when covering ground at 140mph thats good... cobsidering you gobble distance at the rate of 30 seconds per mile... ;)

When a faster car comes up behind - let them pas and get about 1/8 mile ahead and be the "rabbit'.. :)

Know the roads you travel on - and if it "feels right" to slow down... do it.. :) This instinct has saved me many times as I run up on an unmarked car... :D

I think the Vette is one of the most fuel efficient sports cars around - you might get 25 mpg when cruising about at 70 mph (of course RC wont know what i mean :wink: )

I think the 4 mpg must be because he was in the hard acceleration mode - i mean the Vette must be in third/fourth gear.

My S4 is pretty fuel efficient on the highway for a heavy piggie:
- 75 mph on cruise control - 26 mpg+ depending on traffic
- 90 mph on cruise - 21.9 mpg
- 120 mph (definitely not on cruise) - 15 mpg (approximate)

Of course I am refering to the US gallon here (3.75 l)

i get on average, between 30 and 35mpg on the freeway! between 80 and 90mph. :)

but on the downside...in the city, i get about 16mpg :(

have you EVER seen a mileage chart that says 16/33mpg? LOL. ridiculous!

That's stunning fuel economy for such a fast pace. In the city I also get anywhere between 15 - 19 mpg - if it is a complete stop-go situation it drops to 12/13 mpg - fucking Testarossa numbers :)

That's just because my car weights about 300 lb more than yours - I carry the equivalent of a "Bubba" around all the time :)

[RC45]

:) Yes - that is 70% throttle... in 4th going for 5th.

Sustained 10% throttle at 70mph sees25mpg institaneous consumptio and about 20mpg average for the entire trip - stop/idle/go.

But anytime you are 60%+ throttle the V8 shows it's true colours - and crusing at 120+ is a sustained 8mpg with instantaneous 4mpg as shown.. :)

Slip that puppy into 6th gear at 80mph and you get 28mpg.. :D.

But who wants to cruise in 6th at 1200rpm when you could be in 5th at 3500 - or better yeat 4th at 6000 :) :twisted:

[sameerrao]

Man that's serious lengthening of the top two gears - my car drops about 800- 1100 rpms or so from 4th to 5th to 6th.

Yours falls off a cliff. 6000-3500-1200. Do you get any worthwhile acceleration in 6th at all... seems like a useless gear to me

[BADMIHAI]

Of course he does. 100-160 mph in 2 s. and 160-242 mph in 3 s. And all at 28 mpg. because A. It's a Corvette and B. It's in 6th gear. Of course, only rocketed off from a plane. :twisted:

On the other hand you are one brave driver. Sustaining 110 mph is almost begging to get caught. :mrgreen:

[mindgam3]

i think 6th in the corvette is an overdrive gear is it not RC?

[sameerrao]

i think 6th in the corvette is an overdrive gear is it not RC?

Yes ... If I recall it reaches it top speed in 5th not 6th... it was something to boost fuel mileage along with the 1st to fourth shift under part throttle.

[nthfinity]

magazine data shows this, or something similar for the Z
6th gear accelleration from 50-70mph 11.1 seconds
for the C6
6th gear accelleration is 9.6 seconds

if my memory serves accurately... im also thinking that that is actually for 5th gear rather then 6th, since the ratio was changed in the C6

[RC45]

Yes - 6th is a double over-drive. This gear combined with the skip-shift as sameer points out are what qualifies the Vette to by-pass Gas Guzzler Tax and still collect $200... ;) :P

[sameerrao]

Is it possible to substitute 6th gear with a more direct gear with higher gearing ... do you know if anyone has done it ... Would be interested to see the top speed then :)

There was a gent from the Chicago area that used to post on the Z06 forums - he had a custom ratio'ed transmission in his 900hp+ Viper that he was building specifically for top end and 1/4, 1/2 and 1 mile runs.

I have always thought that after a $30,000 engine swap a $10,000 custom ration transmission would be the perfect mod.

With a taller rear end, and closer raitos like the Macca F1 even a 750hp Vette would surely be able to run to 250mph+ (considering the LPE 427TT already runs to 220ish.

it would certainly have the power, but the aerodynamics and stability at those sort of speeds is a different matter. ;)

If it really was tht easy i think we'd see alot more cars breaking the 230/240 barrier ;)

Actually it is that easy. :)

Withness the number of 200mh++ Turbo charged Vtees and Vipers.

They all run to way over 200mph with the stock transmissions - they just run shorter rear ends to get a usable 6th - they may just not make it to 200mph in under a mile.... :P

The Viper and the Vette are plenty aerodynamic enough... :)

[mindgam3]

as i said, if it was that easy we'd see a lot more supercars going at those sort of speeds ;) And a vaguely aerodynamic shape doesent neccesarily equal stability, theres lots of underbody work that provides stability n unless you have a windtunnel makes it fairly hard to tidy up the underneath of a vette or viper.

Having said that, im willing to be proven wrong ;)

"Able to" does not equal "doing it". Did you see that Mercedes CLK GTR fly at LeMans? :?: :|

I read about some Lingenfelter Vettes hit 200 mph in the past - I dont recall any aero issues though some of them had engine/clutch issues as might be typical to tuned cars...

You can lay the same issue at the doorstep of RUF and other tuners as well. The Rturbo may be stable at 180mph or less but after that is it certain that it can handle 205 mph?

And remember the Mclaren has a instability window also in the 200 mph + category (I think between 210 and 220) but it is smooth before and after that.

I guess the SLR might be the most stable with its weight distribution...

All this is academic because it is rare that you will be do a sustained 200 mph anyway unless you work at the Nardi track.

And GM have the technical knowhow to get the aero done as they have high speed experience with the C5-Rs

For most people 200 mph is just a bragging right.

Even on the 'Bahn the realistic top speeds are around 140 mph.

But who wants to cruise in 6th at 1200rpm

you would if u lived in the UK with your vette,lol dam petrol prices have risen this week,place i go its now 81.9p a litre and all the other places are at 83.9p a litre.its gettin stupid.

RC i gotta ask,how many miles do u get on a full tank and "your" driving?

[gottacatchup]

pshh 4.5 is nothing.

My brother's truck makes 8 mpg on a good tank. If it was manual so he could run it hard and keep it in the upper rev ranges i have no doubt it would get 2 mpg.

[coombsie66]

I must say, even my car seems to drink the old petrol pretty ridiculously when you find yourself in moments like these: :wink:

Nice speed.. And nice fuel comsumption :P

I'm gonna get one of those radars

Cheers!
