I drove my 418 hp turbo 2 from st. Louis down to springfield MO for thanksgiving. I filled up before i got on the highway and set the tripometer. At 192 miles i went to a gas station and filled up again. I hads used 10.6 gallons. 192/ 10.6=18.1 mpg. The car probably only saw around 5 psi at the most when going up hill or passing, average speed around 85-95 between 3 and 4000rpm. Just wondering what other people r getting. I was impressed, i was hoping for around twelve.
thanks john

 

i guess no one else really cares what mpg their getting in their single turbo rx7?

 

I usually get 16-20 on highway trips, it is still fairly hilly in this area so you can rarely completely baby it.

 

those 24's r lookin good. there r some hills in MO, but there was a shitload of trucks to pass.

 

With my A-Spec 35R single (and countless other mods) tuned by me on the street I can get 21-22mpg. This is on the highway, no boost, 60-75mph, mostly level ground, Wisconsin 93 octane gas (no ethanol), tuning by me on the street, premix at 1oz/2 gal, etc etc.
