Careful in comparing dyno results from different machines, days, states, and dyno type. It's somewhat misleading if you are trying to apple to apple data.
Wish I had more E85 options by me. I'd love to run some cooler fuel on the stock engine and push some more boost through it...
Absolutely agree with this. Dyno's are a tool for measuring and different dyno's measure differently. The best way to use a dyno is to get 3 pre-modification runs that all line up, then make the change and then get 3 post modification runs that all line up. See what the power delta is and if it was a positive or negative change, or what you wanted and proceed from there. When testing new products for power it is actually even better to get 3 pre dyno's that all line up, 3 post dynos that all line up and then go back to the original setup and make sure it lines up with the original pre dyno runs, A-B-A testing is great and will really show if you are making positive changes. While running the dyno it is also important to make sure you are starting the runs at the same coolant temperature and intake air temperature since those will have an effect on power. Ideally you would also like to monitor transmission, angle drive temperature and oil temperature also to make sure they are consistant on every run. All that being said, comparing a dynojet readings to a dynocom or dynopak readings in different parts of the country, in different weather conditions really doesn't mean much.
As for E85, it is lots of fun, but we prefer water/meth injection and have done that a lot on higher horsepower builds. We typically tune for using the -20 windshield washer fluid and gain around 10% at the wheel, about the same as E85 and if you run out of the windshield washer fluid you can pick it up at almost any gas station or autoparts store.
