What will the mileage drop to after a cam install with various cam options:

264's mileage?
272's mileage?

Just looking for the differance...

 

If you are looking for good "milage" just stick with the stock cams. I get around 12-14 mpg with my setup.

 

what engine management are u using?

 

Super AFR for fuel management

 

i should of been more specific. I wanted to know what is the gas mileage difference between these two differing duration cams. Since from what I have read the 272's are rough idle etc. they would probably use more gas. Also, I watched the video with the fq400 and the tester mentioned it getting 6 mpg. As far as engine mgmt, I have nothing yet. Just looking to get more info on cams, which will be my next step...

 

I have 264i/272e and get about the 15-18 mpg. I have a dynoflash and use an AFC and it idles like *** sometimes and even dies from time to time...

 

I have the 3076 AMS turbo w/ all the supporting mods, 780cc injectors, AEM, 272/272 etc... I got 23mpg highway cruising at 70-80mph.

 

I guess it really depends on tune from what I am seeing. Appreciate the info...

 

Making 375 wheel HP on a dynapack AWD dyno on a daily basis, if I can resist putting my right foot down I get around 27 mpg on highway trips. This is stock turbo, stock internals but stand alone engine management and 272 intake and exhaust cams from HKS.

PS: I know you want info on the differences between 264's and 272's but I don't know of anyone who has run both with all other conditions the same.

 

Thx Kieth, the more I read re. the mileage, the more it looks like the tunning is critical. I just dont want to install cams without EM and get 8 mpg. Anyway I appreciate the post. thx.

 

I have the 272s with turbotrix flash and I got 26mpg on a recent trip to Florida.

 

Which stand alone are you running? What are your mods? 27 mpg is phenominal!

 

Cams actually ADD gas milage, they make the car more efficient, now this only works if you STAY OFF THE BOOST! i get great milage with my 272's, if I get on it, well it burns fast.....

 

I concur with uniami80, I immediately experienced better gas mileage with my 272's, off boost of course.

 

hwang and umi, are you running 272 i & e?
