i would def like to learn more about your H62. i wish i had that blower post some pics man.

 

BlackMagic - With my tune you should seriously be extremely close to 300whp. In comparison for you, I ran a 2.8 pulley, methanol injection, and A LOT of timing and dyno'd 289whp. Since then I have learned a few "tricks" with tuning and am pretty certain that I could have made that a 293ish pull. I am currently on e85 and a 2.7 tvs on 80lbers that are maxed out. Even with the 80lbers maxed out I am making crazy amounts of power. Here is a small comparison. A friends car is on the tvs, 2.9 pulley, no meth and 19 degrees of timing. My car on the "base e85 tune" was running a slightly rich afr, 10 degrees of timing, and the 2.7 tvs pulley. I beat the 19 degree timing car by 1 to 1 1/2 cars roughly from 40 to 120. How or why, I still haven't figured out lol.

Let me shed some light on why e85 is so great though. Some people have asked why e85 is better and what benefits it has for you and what gas mileage is like. I am getting ready to make a huge post all about that, but in short I will touch base on it here. E85 uses roughly from my math about 22% more fuel. People say "about 30% more" and they are pretty close. I noticed that on my first fill up on e85 and the first time tuning ve and my maf, I had to multiply the entire board by 22% to get it running half way decent. Then from there I had to add more fuel and take some out in certain areas.

With that being said, you are using a lot more fuel no doubt about it. However I generally get 320-350 miles on a tank of 93 pump gas depending on how much my foot is in it. On E85 I can get anywhere from 260-280 depending on how much my foot is in it and it's pretty cheap around here. It's actually cheaper *where I live* to run e85 then 93 if you do the math.

So the first perk we have is that it's cheaper, the second perk we have is the added octane. Our cars LOVE timing, it's how they make power. For example take a tvs owner who doesn't have methanol injection, who is only running 91 octane because thats all they have and is on a decently sized 2.7 pulley. Depending on a lot of variables the car is only going to take to X amount of timing, I am going to say that timing is below 18 from personal experience. Certain cells will have knock and not like anything over 15 more then likely. Now take that same car and put it on e85. The extra octane will allow you to run 25 degrees of timing, OR MORE throughout your entire rpm band.

A lot of m62 owners spray a lot of meth to obtain a 25 degree timing number, and still on occasion will have slight knock. They get a kink in there line, the nozzle gets dirty, or the system runs out of meth and BOOM there goes your motor. On e85 it's a constant 100+ octane, it's like you are running on c16 race gas at all times, or spraying 100% meth at all times, without the hassle of anything breaking.

So not only does e85 not use an obnoxious amount of fuel like some people are thinking, 260-280 to a tank isn't bad, it's what some improperly tuned 91-93 octane guys are seeing, but you have the extra added "safety" to know that your motor will NOT have knock even with extremely high amounts of timing. Last but not least e85 runs cooler, and keeps egt's slightly lower and cyl temps lower which can lead to a longer life on your engine.

So first and foremost you need 80lbers or larger to run e85, secondly you must be tuned for both 80lbers and e85, and lastly enjoy the smell of corn

 

It helps with the down low timing to help with torque too

 

TROOF! Down low timing is awesome!
