Like it says. I have an 01 Z28 thats been modded out. Cam headers intake stall nitrous suspension etc. At first I was only concerned about goin fast, but now I have a car that is way too loud, gets dismal gas mileage, and still has a crappy 10 bolt rear. So Im thinkin of upgrading to an 03 Cobra. With just full exhaust and pulley I could be gettin up closer to 500 rwhp with much more daily driveability than my sub 400 rwhp LS1. So I was wondering what kinda gas mileage a slightly modded one gets?
I have a 03 cobra with borla stnger cat back,predator tune,steed cold air and 295 on 18s in the rear ,soon to be 17 by 10.5 with 315s .I get between 15 and 17mpg.Don't know about mpg with a pulley,but I will real soon!
gas No Pulley, but 400+hp at wheels and I get 15mpg city, 18mpg avg, and about 21mpg hwy. Pulley change is in the works.
