Yeah, I noticed that too (the gear ratio differences). Right now, I'm gonna be running a cheap eBay intake. I just don't have time to get my Volant one installed. I'd rather get my HID's done first.Well, I got 17-18mpg with my '97 S10 4.3L 5spd in the winter and 20-22 in the fall that I had it.FYI, before I started modding my Blazer, I got 20+ MPG in the winter
The ZR2 Blazer was the worst because of the parachute/spare tire hanging off the back... The pickup ZR2 will be about the same as a regular 4x4 S10.
It would be great to stay around 18mpg for the winter!
I thought the bigger tires were what killed the ZR2's.
Most non-Z S-series with stick shift were 3.42 gears, you've got 3.73's so it comes to close to the same
Intake + exhaust + BB tune and you should be able to average 18 easy
I got by BB tune for 87oct. Nothing fancy. I still need to do the TB mod though.
We'll see how accurate the DIC in the OHC is for calculating the AVG MPG. The Instant MPG jumps all over the place. I saw as low as 7 and as high as 30.Of course, that's WOT and off the throttle entirely.
The average was usually pretty close... Within 1 MPG, usually, for me.
I've gotten as low as 0 and as high as 99
