Your best bet for high octane UNLEADED FUEL is to pick up race fuel CONCENTRATE... This is NOT the cheap octane booster stuff (that doesn't work) at the auto parts store... I know a few guys that swear by the Torco race fuel concentrate:

Only 4?? lol.

I wish I had 4. I have 2 on my daily route. One near home and one near my job. One is charging close to 4 dollars per gallon and the other one is always cheaper than 87. The crazy thing is that they both get it from the same company.

[hapisok]

HWhat!!! $4/gal? that is insane! i just filled up for the first time this past year for under $50...E85 at $2.95 not that its any cheaper since its harder to keep my foot from burying the pedal every chance i get.

you don't need any "extra parts" for the ethanol tune, assuming you're already running Vince's tune and have the cables, its only $100 for the E85 tune. run your gas almost dry, add a couple gallons of E85 and put 5-10 miles on it. then load the E85 tune, burn that down to get the residual gas/ethanol mixture out, and then fill up with E85. its a little bit of work at first, but worth it.

not to mention, like previously stated, your engine will run hotter using a higher octane gas. some of the benefits include 1. engine runs cooler avoiding possible damage caused by pre-detonation. 2. great for higher compression engines where more power is able to be produced in comparison to gas...enter FI! but you'll see a drop in your MPG's as more fuel is needed to so there are some drawbacks to it also.

here is a blurb i pulled from the almighty WIKIpedia referencing E85 in comparison to its octane rating...take it for what it is...its wikipedia for godsake:

"If a retailer chooses to post octane, they should be aware that the often cited 105 octane is incorrect. This number was derived by using ethanol’s blending octane value in gasoline. This is not the proper way to calculate the octane of E85. Ethanol’s true octane value should be used to calculate E85’s octane value. This results in an octane range of 94-96 (R+M)/2. These calculations have been confirmed by actual-octane engine tests." [7]
Examples of this mis-citation can be found at the Iowa Renewable Fuels Association titled "E85 Facts"[8] which cites a range of 100-105, and a document at the Texas State Energy Conservation Office titled "Ethanol"[9], which cites a 113 rating."

thanks to jay, i've learned the importance of monitoring what is going on with your engine once you've strayed from your stock settings. just because you put a tune on it doesn't mean your good to go. two camaro's with the same mileage, same mods, same tune, aren't gonna run the exact same tune.

with that said, im currently awaiting an updated tune from vince for E85. my LTFT's were climbing into the 20-30's...highest i've seen it climb is 35 , triggering a CEL. once i get those numbers back to normal, marilyn will be back on the dyno.

[bmorecam]

Aaron, your LTFT is still climbing in the 20's? I thought vince took care of it. If you are still having fuel trim issues then that is crazy. Vince is back to work today so hopefully he can get the trims corrected soon.

[hapisok]

Last time they started climbing (was on E85) I didn't hear back from Vince for a week, so I went back to 93 octane. Was still having issues with my LTFT's then too but those are straight now...so back to E85. Can't wait to get these resolved. I sent a data log off to Vince the other day and he said he would take a look at it...hopefully sooner than later.

Stupid question:

Can I still use my engine cover?

I was just logging in to ask this same question. So no it wasn't a stupid question. Lol

Not a stupid question at all. I had plans for mine as well, they disappeared after about an hour...but worth it. Like others have done, you can powder coat your IM. But yeah, you lose that customization...sorry bro. But on the other hand...its a challenge to customize your IM.

Good luck, can't wait to see what you come up with.

Aaron, can't wait to see the total number with e85 and the insulator

Don't worry about the plane gas LOL. Go with e85 if you want to go with higher octane gas.

That reminds me- Bmore (Jay), is your IM back in use and is your paint holding up?
I've gotten some high temp primer/color/clear and had planned to paint when I had the IM off for insulator install.
Then I remembered we're talking about aluminum here- notoriously difficult to paint.
Any update on yours would be appreciated. Would suck if it peeled!
Thanks!

Is holding up beautifully Just take some good prep work and make sure that you use high temp paint and clear if you want some shine, but with the 25mm insulator the IM never get hot or even warm to touch.

That shows how well this works. Touch the intake on a stock LLT after running and it is cooking, the insulator makes a tremendous difference in the heat soak. The cooler the intake air charge, the more room for oxygen molecues, the more fuel and the more power.
