I am getting -14 to -15, my friend.

I understand your point, my friend. That is a nice option and not overkill from a price perspective.

Thank you, my friend. The powerband is outstanding in my opinion. The car gets all sorts of respect here on the streets. I get guys from big country trucks asking me to punch it, to guys just coming up to the car to slobber over it. I am respectful to them all and entertain all of their questions. There was even an old man that stopped me in the gas station and said, "It looks like that car is serious.". I said, "Yes, sir. He is pretty serious."

Yes, I am still on the stock transmission at 108,000 miles. I did what I could to address the drivetrain aspect of the build while not having to worry about replacing the transmission. I do not launch the car at all and when I go to the track, I usually baby it off the line.

For the E85, yes, the is with the 91-octane still in the tank and the very first pull. I have since gone through nearly an entire full tank so there should be nearly all E85 in there at the moment. I plan to do another log here in the near future and send to Tom for his review. And for the IDCs, Tom will have to weigh in on this as I am not sure. I do know that AFRs were 11.7 in the upper RPM range.

Thank you. What is your idle set at? 1000?

Could be putting that 255 to its limit but looks like a fun build.

*disregard. I see plans for a 400. Does anyone ever think of the out of tank pump options out there?

Yea, I ran out of pump with a re-wired 255/ID1000s at around 500whp on pump gas. May have been able to push a little bit more with larger injectors though...

Right now, my idle is set about 1,050 RPM. It has a very nice rumble and sounds like a small truck. Lovely.

Yes, the 400lph is in the works as I know it will give me more headroom. I do my best to do all things with safety in mind.

I think its the ethanol content. First tank of E85 means mixing 1-2 gallons of gasoline with E85 and gives something closer to E60. Requires less fuel and still has roughly the same performance potential as E85.

Valid point. Well he's got safety in mind with a larger capacity line system and pump in the future. Would def keep an eye on things when running a full tank of e85 though.

Safety, first and foremost, my friend. Like I said, I will send another log to Tom probably Sunday evening to see if any tweaks need to be made since there will be more pure E85 in the tank instead of the diluted mixture of 91-octane and E85.

14-15 @ 1050 is not bad at all with the S2s.... I bet running SD is helping also...

Would love to hear the idle on that 2.4LR motor with the S2s...

My car with a 2.4l and s2's barely pulls any vacuum at idle. Gotta look over the idle situation. Sounds serious though.

Strange as Tom did not mention anything out of order when he veriified the same thing for me. I am not saying that I do not believe you, my friend. I am just trying to see what the tolerances are for my set up in comparison to others.
