With june 12 rapidly approaching and the c16 in my tank getting lower I'm gonna do a mid season fuel change. I know the Eth and Meth are popular but I stubled into a drum of VP import (thanks Ernie) Now obviously im gonna fine tune it on the dyno and up my timing from the 15Deg of adv it has now. Jim from JPR said he heard it was like 30% more due to the fact its oxygentated. But I find that to be a bit much. Just want to add fuel to the maps b4 I hit the dyno to get a safe base line.

 

Well I had to add 5% more when I switched to Q16 (oxygenated) from C16, I doubt if VP Import would be that much more

 

That sounds more right, I thought 30% was for e85, and 50% more for meth

 

Figure atleast 30% if not more

 

You'll need to upgrade those fuel lines

 

What kind of fuel pump u running

 

Dual warlboro 225's , 1 feeding each rail

 

how much?

 

going from c16 to VP Import on average you'll be adding somewhere between 5~10%

Make sure to flush out VP Import if your not using your car as it does tend to corrode.
