I dynoned back to back to compare the two fuels.
Made 675whp @ 35psi on e85 717whp @ same boost on e98
Went to 38psi made 730 on e98
Setup
Benson sleeved 83mm gsr
Hta86
Id2000s
Two 044s
Almost 40 more hp @ same boost.

 

That's awesome! Can't wait to start using e98.

 

this might be "classified" info but i figure ill ask.

how much more timing were you able to run on the e98 compared to the e85?

 

x2 on clasified info... what sort of gas scale AFR were you able to do on both?
