Performance idea...

[Strieg]

Anyone ever thought or tried to use WMI on these?

Are we talking water-methanol injection? I thought the big thing was E85 for performance these days? There are a couple turbo imports running around my neck of the woods who did E85 conversions because it's 105+ octane, readily available (320+ stations here in MN), and burns cooler.

Yeah water/meth. E85 is good, but water/meth, IMO is better for the regular person.
Look at snow performance. That's where I got my kit...
But off 91 oct you get around 109-110 oct, and I get sub ambient air temps. And it's CHEEP! around 3$ a gal for the meth, .75 for distiller water so well say 5$ (rounded up ALOT) for 2 gal of water meth, and depending on driver habits... That'll last a month.

I guess I'm spoiled.... I paid $2.43/gal last fill up in my truck.

For? Gasoline? That is pretty cheap, but I was talking about water/meth injection...

No, E85

That's pretty sweet. What kind of power are you seeing?

I've never dyno'd it but the manual says I'm supposed to gain about 10HP and 12 ft/lbs with E85, and I'd believe it. It's also a known issue with 3.0's that they love to ping, and my friend has gotten to the point that he sometimes runs midgrade in his even though it's stock and it runs better. So I guess not only is my engine NOT pinging, but it's gaining a bit of power on top. The 99 3.0's have an alcohol sensor, 24 lbs. injectors, and different combustion chambers as well. The tech library shows some of the differences between ethanol heads and standard heads, so my motor is actually a little different. The fuel lines are bigger as well (found that out when I accidentally bought the wrong fuel filter once lol), so I'd imagine if you had a factory E85 engine, that'd be easier for tinkering with E85 than trying to convert something - they've done a fair bit of changes just for the ethanol.

I do want to look into a retune sine I've burned nothing but E85 for half a decade in it. Winter starts don't seem to be the issue I've heard, and we had a lot of subzero weather this last winter. I'm just curious how much room is left to play with spark advance and such. I don't recall off the top of my head what the compression is on my motor, but I wonder if I could increase the compression to take advantage of the higher octane fuel...

That seems to be biggest problem I see, lack of tuning applications

I've seen people on here mention tuners but seems like mostly a 4.0 thing.

That's what I mean, doesn't seem to be any options for the 2.9
