MPG on a cam - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

LS3_JC · 07-29-2021, 02:26 PM

My car is a 2012 camaro 1ss manual currently its stock (just an axleback) but I’m looking at a cam in the future, currently I’m getting around 29mpg on the highway and 14 in the city (beating on the throttle occasionally). How much would it tank if I put let’s say a GPI SS3 in it? The car is my daily driver btw.

This question has been answered numerous times. The search button at the top right is your friend. But I went from 23 mpg on the highway to 21-22 mpg at around 70 mph with the GPI SS1 camshaft. I don't know how you get 29 mpg.

a lot will depend on the tune and the overall combination. All an aftermarket performancr cam does is open the valves higher and longer than a stock one.

The more air that goes through the motor, the more fuel it will consume

If I drive mine normal without getting on it, its almost the same as stock, maybe a little lower but overall not too bad.

I'm running a Night Fury cam. I went from 18 MPG to 15 MPG. I think that's more the Tune than just the mechanics of the Cam.

I get an avg of 200 miles to the tank, sometimes way waaaaaaaaay less. I also use E85 and I’m cammed/boosted. If you’re worried about gas consumption… don’t do it.

Mpg on e85 gets shocking even on the stock cam

You will lose significant fuel mileage witht that cam. Dont mod if losing that bothers you. With my setup now, i think im in the negatives somehow lol

Never experienced on a stock cam. I remember at 1 point I saw an avg of 3mpg on the DIC

Fbo cammed geared and stalled here. Not enough of a difference to be concerned.

wasthatacop? · 08-05-2021, 11:35 PM
