5.0 on E85, anyone running it?

**Mark Aubele** · 05-28-2015, 11:02 PM

Picked up a set of LU47s, planning on going to E85 on the '14 over the weekend. Been reading about a bunch of wideband failures from moisture issues with longtubes where they are mounted horizontally (basically every header except Kooks, I have Pypes stepped longtubes).

Anyone running E85? Trying to see if it is overblown or not. Might just have to relocate sensors so they are pointed downwards, which seems to solve the issue.

I am going with it before long I already have kooks ,

1. Placement for and aft may have an effect on the 02's. Some wrap the headers to retain the heat. They have a heater in them and if down stream too far may cause heater to prematurely expire.
2. Angle of 02. Some manufacturers place them in the 3 and 9 o'clock and the moisture can collect on them. Supposedly cracking the ceramic. Adjusting angle to allow moisture to not collect is an option.
3. Kooks mid length headers have the 02's positioned in such a manner that many e85 users do not take out the 02's. Not saying nobody has had an issue. Two coyotes I know of have the kooks and are free from that issue.

Yes it seems that the Kooks do not have the issue. May try wrapping mine and carry a spare sensor, seems some have had success.

Which headers do you have?

**Mark Aubele** · 05-29-2015, 04:20 PM

Pypes LT.

One of the few that offer a step design.

Yes, that's why I ended up with them. Think I'll try the header wrap and see if that works.

They would go nice with some cams.

Yes they would. Unfortunately the class I race in requires a stock long block. Still debating on the Boss intake or not, not sure if I wanna deal shifting it at 7500+, already doesn't really like going into second much over 7200 (don't normally shift that high, was just testing to see how it shifted).

I just got mine tuned with the cobra jet and this new rpm is addicting,

**Mark Aubele** · 05-29-2015, 07:08 PM

Oh yeah, I would love to rev it. Just want to get the twin disc and shifter first. Done dumping money into it for a while. Just ordered a new set of 315 Hoosier A7s so no mods for a few weeks :)

It's not uncommon to pick up 14-18 rwhp on corn. It was well worth it with availability within 15-25 min.

Speedway literally a mile from my house. Just gonna have to take some with me to the track/hillclimbs.

Nice! Speedway just opened a little while ago in Perryopolis. Tested it a few day ago and topped the tank off. Checked out about 85-86. Mpg went from about 26 to 19 on the highway.
