Default E85 dyno results

Car is a 2009 automatic with 3600 stall, ECS1500, g6x3 cam, full exhaust, etc..
Now has A&A dual pump system, Id1300s and dsx flex fuel sensor. Restrictor plate still in place on supercharger.

Previously on 93 octane made 623/542
Now on E85 makes 685/595

Really happy with the numbers and can't wait to pick it up this Friday and drive it.

Original tune was 93 octane only? Good numbers for comparison.

Any idea on total timing advance at WOT between both tunes?

Yes 93 only. I do not know about the timing but can check with my tuner.

Thanks for posting. I've always wondered what kind of difference it would be going from 93 to E85. From the numbers it looks nice, but not sure it's worth the cost of upgrading the fuel system for me since I already have meth set up.

Awesomesauce. I love the stuff. Flex fuel is one of the best mods I've done.

I'd be more curious of 93 + meth vs E85. I run E85 on my daily driver

Would love to see a comparison of the two options. I'll even volunteer my car as a test platform if anyone wants to help fund the fuel system upgrade.

Exactly. It's a no-brainer E85 > 93. I used to run 93 with and without meth on my C6. Going from 93 to E85 feels like the same jump on my GTR but this is obviously all just seat of the pants feeling.

I'm doing the flex fuel conversion myself as I really really don't want to run meth and there are 4 Kroger's in my local area that have E85. Keeping it simple with a Bosch 044 and 82lb/hr injectors from FIC (stock injectors punched out). Gonna run her unrestricted and see what she makes, I'm guessing it will be +/- 700whp. I think I'm at around $500 for my setup

Evan, if you want to do the flex fuel conversion you can either buy the Flex Fuel kit from DMS ($400 but plug and play) or simply buy the sensor and build your own lines. There are instructions on where to pin the sensor into your PCM. All you need is your tuner to activate the tables and boom...you can fill up at either pump and the ecu will correct for octane on its own.

The GM Flex Fuel sensor part number is: 13577429
The GM Flex Fuel Sensor pigtail part number is: 13352241

Not concerned with the cost of the flex fuel setup, rather it's the cost of a fuel system upgrade. I'd have to either upgrade to a Fore system or A&A/ECS add-on system to supply enough fuel to run E85. Also, I'm just not sure E85 is going to make any more power than 93 w/ meth.

What did you do to your car? If you're guessing 700RW with E85, you must be at 600+RW now.

Why do you think that you need to upgrade the fuel system with a Fore dual pump system or the ECS add on for 7xxwhp? You can run a single Walbro 450 and a Bosch 044 in line and supply enough fuel to upgraded injectors.

E85 may make the same or a bit more than 93+Meth, but it's worth it to run it over meth because you won't have to worry about it running out or having a Meth system malfunction. Do the Flex Fuel conversion and never worry about getting meth again.

Any way you look at it, it's still an upgrade to the fuel system plus the flex fuel setup and updated tune. And if I'm going to go through all that headache, then I might as well go full retard and do 3.4" pulley, long tubes and cam at the same time. Of course if I do all that, I'll really need something like a ProEFI for traction control as I'm already traction limited.
Thus I think I'll just leave it where it's at and enjoy it.
And there's really no worry with running meth, I pick up 5 gallons at a time and it typically lasts me 3-6 months, which is way easier than worrying about finding a station with E85.

Traction limited? I have a C6Z on a 200 shot and dead hook at a 60 roll. Have you ever heard of drag radials? Pro efi what a waste for a sub 1600rw vette.

I think you're overcomplicating this in your head E. How in the heck are you traction limited at sub 7xxwhp? 7xxwhp isn't full retard, that's mid level street car power. Full retard is a little over double that.

Are you not running drag radials yet? There are people making A LOT more than you or I that are still perfectly ok on DRs running a stock ecu with HPTuners. ProEFI? For a sub 1,000whp car?

I agree, your car is overdue for LTs and a cam..but that's more for sound and fun factor. Even after cam and LTs you'll be lucky to break 750 on 93/meth and if you do you'll be working that blower hard at that point anyway.

Yeah, not understanding the need for ProEFI for that power level.

I wouldn't say sub 1000whp has no need for it but sub 800 definitely doesn't have a need for it.
