I used to get 25-30 miles to the gallon b4 I replaced my clutch without ac on and VTECing it here and there. Ever since I replaced my clutch with the ACT Street Disk with the Xtreme Pressure Plate, I've been getting 30+ miles to the gallon even with a VTEC here and there. Could it be that the new clutch helped improve it in anyway or is it that the weather is just cooler and makes the car run more efficiently?

 

same thing happened with mine!
I dont know how this works but im sure not minding it
In theory it would seem that the extra grip is not wasting as much of the engines power? if that makes sense? I dunno I think its great though

 

I used to get 25-26 mpg on my stock clutch

Then I put in the exedy street/fidanza flywheel and now I get 20-22.
