I was looking on some imput on what type of gas mileage you guys are getting with the different cams. I'm mainly looking for the hot cam, cc305, XE 218/224, and XE 224/230. It doesn't matter if you have tuning or you don't. I know, i know, your not supposed to worry about gas mileage, but my car is a daily driver. Thanks guys, i really appreciate any imput!

Just got the hotcam & it seems to be getting about 18 MPG.

 

I'd expect about a 3mpg drop or so from the cams you've listed.

 

14 city 20 hwy

 

I was getting 27 mpg on the highway with hotcam, stock heads, LTs, and a M6.

 

get about 15-16 in the city, and around 20+ on the interstate.
Thats with CC306 and 4.10s and crappy tuning.

 

On my old 94Z, CC305, mildy ported heads, A4 3.23, I got about 15 mpg in the city, and around 23 or a little more on the interstate....

 

With the mods I have in my sig, I'm getting 10-12mpg in the city, and 14 on the highway. I drive 75mph on the highway (about 2850rpm with 3.73's) which is why I only get 14mpg or so. In town I just have a lead foot and raised shift points, hence the 12mpg. Also my heads are pretty hogged out and have 2.02/1.60 valves which isn't helping fuel effeciency.

If your keeping your heads stock, keeping 3.23's, and the car has a decent tune, you should be able to get 14 or 15mpg in the city, and 17 or 18 on the highway.

 

if you port your heads wouldnt you get more mpg then a hotcam with stock heads?

 

I have the Xe 224/230 and get about 8 mile to a gallon. I also have 3:73 gear and a six speed.

 

Here's my gas mileage- when the tank gets close to empty I fill it up. The way I drive, knowing the actual numbers would just be depressing.

 

ACA performace

Why would you say that??? Running 110 octane and 12.7 comp with 3.73's . Just trying to understand why you would think that.

 

I'm only getting about 130 miles per tank with the mods in the sig. Hopefully I can gain a few more MPG with some different programming.

 

I get 24 on the highway....thats with 400rwhp to . City is a different story. I think its around 10. Right foot mod at its best!!

 

I get about 12 around town and about 19 with a city/Hwy. combination. Dunno about straight hwy driving but it will go over 20. With the mods listed below.
