Wow, fantastic power.

What's the difference? Just run a ton of timing in the base map and CPS when needed.

I don't think he was trying to; it was a fuel pump issue he's been having for the past week. If you look at his second log with methanol supplementing fueling, the A/F ratio looks better.

Here is my log with a "healthy" LPFP/HPFP, if you compare the black line on the graph with Terry's, his drops or remains flat.

I'm not sure why this method isn't being used it's the G5 board, it has CPS, so i'm not sure why?

For comparison, what timing do you run up top?

I'm currently hitting 14.2 degrees @ 6905rpm, 17psi, timing correction value 0 (I overboost by 2-3psi above 6,000rpm because of my sticky, old, rattling wastegates ) running a 38% ethanol blend

6905? I wish my auto could get there. it auto shifts at like 6750-6800.

But yeah you should easily be able to get 14 degrees up top. You may be able to inch higher if it makes power and the car tells you it's happy.

Edit- saw you run a JB4 only. Well ignition target is tied to perceived load in your case, but same concept applies.

For these runs the advance curve was set with straight E85 in mind. With methanol also in the mix, it should be able to take another degree or two at higher RPM for an additional power boost up there. There is also plenty more boost on tap when needed. Their main objective with this testing was to see where the car stands currently on E85 only.

"rb turbo E85 dyno" srsly?

[enrita]

He means the gas octane , 91/93....

He normally runs 91 octane + 1 bottle NOS octane booster.

looks good, i am interested as well to see if how these cars would handle pure e85 for extended periods of time.

at least 8 months running consistantly at least a 40%-50% mix, sometimes running as high as 80-90% for short periods, for me. My fuel pressure logs from above still look healthy.
