real world mpg's

[1fast6]

Went to the Daytona Beach dream cruise this past weekend. Temps were about 85 all weekend. Averaged 21 mpg's on the highway.:smile: I was very suprised. I was expecting around 15.

On another note. I saw the highest KR to date with my car. 7.7 Was my fault.:redface: To save a few cents I ran 89 octane since 90% of the driving was highway driving. Well, I was getting on I-4 and the approach ramp was about 1/2 mile long so I kinda put her to the wood so to speak:redface: saw 7.7 and promptly let out.
I have since ran the 89 octane out and she has a full tank of 93:smile:
18lbs of boost and no KR

that is a nice mpg number ! may i ask how do u read and verify ur mpg ?

 

[northerngn]

I got around 15mpg on the last cruise i went on...
not bad for a 3800 non lock and a fully built motor on E-85 with 85lb injectors.

Do Alky and run 25lbs all the time with no knock. :smile:

I'm seeing about 25mpg mostly highway speed no boost or wot.Better mpg's than the car got when it was new.

Driving very conservative and locking the converter with a switch got me 24. I was surprised considering I have a 212º roller cam.

I drove 2 hours to Bradenton and only used 1/4 tank. Stock cam with 60# injectors. By the way, I run 20 to 21# of boost on 93 octane. In first gear I've hit as high as 23 1/2 with no knock. No alky. Gotta love that Turbo Tweak 6.0 chip!

For you guys getting 20+ at Highway, what is your average speed? I can get 20 if I cruise in o/d at 50-60mph.
If I hit boost regularly I reckon I have single figures
Not sure about the accuracy of 86 digital dash fuel indicator, but after a couple of 1/4 mile boost blasts my fuel 'level' dropped from 11-8 gallons..and didn't come back up!
Feels like i'm fuelling a big block:wink:

A chip with lean cruise can help too.

Had the cruise set between 70-75. Only went WOT the 1 time.
In town getting on the skinny pedal will yield single digit mpg's easy

Don't have a long run on my current setup but with my last combo which was mostly stock I made a run from pheonix to san diego gonig around 55-60 and got 26-27 mpg. I used to get 22-23 on long runs at 75 with that combo. Not sure what the current combo would do because wifey never wants to go for long rides in my car which I can kinda understand......kinda........but not really.

EDIT: FWIW the above mpg numbers where figured starting with a full tank and then filling back up to get the amount of gas used.

easy

Do Alky and run 25lbs all the time with no knock. :smile:

thats not so hard when your running 110oct or 116oct.

 

[BlackBandit]

thats not so hard when your running 110oct or 116oct.

It's not so hard with 91 oct and alky either, especially with a mostly stock setup.

Infinitely more expensive, and unnecessary. :biggrin:

I wouldn't trust any of the gauges in these old things too much. Also more boost(air) = more petrol (for all the English chaps). Plus big blocks are too heavy to have fun. Right? Wait, I got one of those too. Never mind. Actually the big blocks mileage doesn't seem to change cruising at 45mph or 75mph.

I have been driving my car to work this week witchis about 30miles each way. It's a lot of stop and go with all the red lights in Florence SC. I'm getting around 14mpg . Now if I'm on I95 at 65mph Ill get about 18 if I don't hit any BOOSTTTT. But thats hard to do when it run so damn good!!!!

 

[TurboTnZ06]

Took the GN to Reynolds last weekend, 457 miles each way on the GPS, did another 5 miles to get gas for JD and coffee Sat am. Got 20.2 MPG (including 4 track runs) in a car that had to weigh 4100-4200#'s at least with all my tools, food, drinks, chair, camping supplies, etc loaded up. I ran 275 50 17 M&H drag radials, stock engine all the way to the air filter, just TT chip and 60# injectors, 307, fp regulator, and Kirban 3" dp.
