We have a car we are playing with and was wondering how hard the switch is to make. The car is tuned on c16 and runs good but we wanted to switch over to e85 and I was trying to figure out what rise in fuel pressure would get the tuneup somewhat close. The car runs a 50lbs base right now. It has 2 bosch 044 pumps and 1600cc injectors. From what I have seen i am looking at a 40% increase, so would it be as simple as rasing the base pressure to 70? I know it wont be perfect but we are just trying to get it close.

 

so if im understanding correctly your wanting to know if you switch to E85 you can just bump the base pressure to 70?

I would say retune it. you can run both E85 and c16 at 70base pressure

 

e85 flows like 30% more than c16 correct? you can leave the base the same unless you run out of injector. then you turn the base up to get more outta it.

 

Lol bumping up your fuel pressure in your (assuming 800whp setup) is not going to cut it going from Gasoline to Corn, you need a COMPLETE retune.

At your power level (assuming you are making power, 162mph isnt typically a stock sleeve setup) why wouldnt you want your tune perfect??
