i was just wondering if we could get a couple of you guys that have done cam and cam/head swaps to post what you have with mpg #s. i didnt find anything with a search so hopefully i dont get the usual....."do a search, youll find a million posts on this already". btw, im not really new, its been a little while since ive been here though and i cant remember my old username. drive safe

 

i get 8-9 mpg currently on my le2 396 setup on a madz28 tune but i am currently having a problem with my o2 sensors shorting out on the right side
im running 30lb svo injectors stock fp and new opti and stock acdelco plugs w/msd wires. stock maf and tb, dont know what else is causing the bad gas mileage
i also have 3:91 gears and a automatic if this helps

 

10mpg (nyc driving) out of my 400RWHP 6 speed Trans am...

15mpg city / 19mpg hwy with my 383 LE2 6 speed. It has 4.33 gears also. I keep blowing header gaskets, so I am sure it could get better yet.

 

thats pretty good tqdrivenws6. good mpg for what youve got. i had a 95z with bolt ons, a4 w/2200, and 4.10 gears and i thought my 20mpg on the way back from michigan was really good. its good to see some of what people are getting when you want to drive your car all the time and have fun at the same time

 

I dont know about you guys, but I dont mod my camaro for gas milage, I do it for power. If you're worried about mpg, get a beater, thats what I did 30mpg beater = I dont care if I get 10mpg in the camaro when its all done

 

I disagree. There are enough 30 mpg Camaros and Trans Ams on this board that I wouldn't mind joining that club too.

 

Yes but non of them is 11 sec car (like my car). I can get 23-26 mpg on the highway, but city driving is much much different...

How many of them have a heads/cam setup?

 

good grief not that again. why can you not have a fast car and fuel mileage too? i dont understand the problem. if i wanted a race car it would be a different story, but i would like to have a nice, fun street car. thanks.

 

I get about 16 city with 383 847 cam longtubes and a 2800 stall. ed wright dyno tune.

 

Yea im right around 15.5 when i checked last, i took a pure highway trip(with some racing) and got 21.

 

No way you can get that out of 400RWHP h/c F body. Unless your city driving is mostly highway city (not stop and go all the time), or you are driving like my grandma
My car has all new oxygen sensors and fuel filter, plugs, wires, and was dyno tuned by Bryan from pcmforless and I cant even get close to that. My highway MGP is excellent 23-25MPG, but city MPG sucks a donkey *****

Yea my city is not stop and go, i jump on the highway for about 4 miles, then drive 4 miles through the city.

 

So it doesn't count
