3800 Who says modded cars cannot get good Gas Mileage??

[syP]

ON the way to the Mod Day...

Strictly Highway, No cruise control, at 80mph

This is once we got off the main highway... all the way to the actual house

And then beatin the crap outta the car at the mod day.. I still netted 22MPG overall.


Thankyou Denise and Mike for a Great Mod DAy!!



Oh btw... Mike K and anyone else who cared... I put on my stock Throttle Body and RIGHT NOW I am at 0 KR with the 3.2" pulley throughout first and 2nd gear (havnt tried 3rd yet)

Thanks Mike (superchrgdgp) for teachin me about the o2's and to stick with my stock TB

yeah my DIC is nowhere ever close to the actual fuel mileage on a tank of gas though when ya figure it out by acutal miles and fuel put back in tank

 

[syP]

OH.... ya i agree.. on the fillup i DID make it to 320miles on a 17 gallon tank..

which i used 15.3 gallons....

320 / 15.3 = 20.91 MPG round trip... nice

 

[SaturdaysGS]

Nice SYP, and that car pulls hard! I like! I got decent mileage aswell (avg 20), I just need a good tune.

Our tanks hold how many gallons? Its more then 14 right? I can only get 14-14.2 gallons in when im pegging empty, and filling it up till the 5th shutoff or so puts me to above full.

 

[syP]

I coulda swore 17 gallons??

As long as your TB has the correct Maf table in it, any TB will work. If you are on a stock MAF table, the stock TB will work well.


Got 34.xx MPG on the way home from the track, it averages around 24 during the week in traffic.

Dude, pay now or pay later....

Leaving it rich: Safe for awhile, low gas milage, carboned up cylinders causing hot spots and higher compression, washing down cylinder walls, gas in oil/premature bearing wear

Fixing the problem: pain in the ass, have to learn something new, better gas milage, chicks don't tell you you smell like a muffler after you get out of your car, etc...

C'mon; you got a powertuner. Use it!

I really thought the cam was killing my gas mileage and it sort of was since I spent an entire tank tuning it and only got 160 miles out of that tank. I was presently surprised yesterday when I was getting 28mpg out of the cam though.

 

[zeez gtp]

you know what ron, maybe i will use the powertuner.

my lt's are all positive, i thought that meant i was running lean??

 

[CoolGTX]

i've got mine tuned with the mini-afc to get 40.9..thats right, to and from the track yesterday, I was getting 40.9 MPG, cruising at 65-70 MPH, with 3.29 gears and High stall speed torque convertor

at 80 MPH, I still get 35MPG..

 

[WhiteSleeperGTP]

what i think is funny is my 12 sec 95 l67 gets better mileage than my completely stock 00

 

[syP]

Ubend i say... Ubend

 

[HUNTERDOG]

You know after this past mod day I noticed I was getting pretty good mileage too. I finally hit 20MPG. I was always sitting around 14-16 Maybe it was the fresh country air .

 

[syP]

Had to!

 

[GTPPWR]

I had hit 32.0mpg on highway going to and from Ohio. I average...18-24 in the city. or at least I used to.

 

[xierxior]

I average 20mpg city and 28.4mpg on the highway at 85/90mph.. this is with a 3.4 pulley, FWI, autolite 104's, 3inch downpipe w/ ubend delete
