ya i jus t wana know wat the gas milage is fot the s5t2

stock
mild street port
heavy street port




thanx in advance

 

entirly dependent on driving style.

EPA ratings can be found in the Specifications /options sticky thread found at the top of this section and is 17 city and 24 highway.

I would not expect an agressive street port to get better than 12-13 MPG, while a mild could get around 15 MPG- but again that is on how you drive more than anything else. if you granny'd the car and had an aftermarket engine computer you might get 17-18 with even a street port

 

Why would you granny an aggressive streetport?

 

maybe you wanted to get the best gas mileage

 

you can get better than that with an aggressive streetport with a tuned standalone. i can get over 20MPG if i am easy on the throttle.

 

Tuned standalone is the big key

 

My gas guage is never correct, always states that I am on empty.......

 

never specified whether it was on the stock ECU or not

 

I can get 50mpg............downhill.......with the motor off.......the wind behind me.....and no woman in the passenger seat.

As mentioned the tune is going to be a huge factor, but as a general list:

1. driving style (how often do you bury the throttle?)
2. tune (is gas pouring out the tailpipe?)
3. maintenance (this somehwat relates to tune but, are your spark plugs making the most out of the fuel you're burning?)

Those big factors will determine the greater value of your gas mileage. Its relatively hard to say stock port = x.mpg and street port =y.mpg since both cars could have the same mileage if driven two different ways or tuned different ways.

 

I've gotten 22mpg on a S5 TII mild streetport. And that was with a dirty airfilter. It'd probably be better if I cleaned it up a bit more.

 

My '88 Vert is 100% stock, 120k miles, no recent tune-up; it's an S4T2 but it just did 19.4 city/23.3 hwy with the top down.

 

With "normal" driving, i've gotten 10 litres/100 km's on the highway and 14 Litres/100 km's in the city.

87 TII no power mods.

 

i do most of my driving in the city and drive pretty conservitly, my motor has 1500 on it and is getting around 12-14 mpg... with the gotham stage 3 " race port" which i guess would be considered an extremly(?) agresive street port... how ever on the high way on the way back from gotham after the rebuild i was getting about 18 on a brand new engine...oh and that was untuned.... should get better after my tune
