Hes probably good to have both 93/100 tunes and load the 100 tune when needed i suppose. Or spend the money on fuel system and toss the stock blower in a grinder

My brothers running +30 injectors, LPE di pump, DSX low side, and has enough fuel for E60 on a 11:1 LT4 H/C 2650 spinning16psi in his Z06. Should be over 900whp and the log data supports it.

Hell with changing tunes. Spend the money upgrade the fuel system, install a flex sensor and enjoy running some 2.00 a gallon Ethanol or a blend of. Even E60 is still 105-106 octane.

I spoke to the guy tuning my car yesterday and we tentatively have Oct 1st as a flex fuel install date. He is pretty confident on e40 and possibly e50. I have not done any high side mods yet so it will be interesting.
I also questioned him on the higher than norm Lambda and he pretty much said he has tuned many leaner than most without issue. Just cause others run them on the rich side doesn't mean he is wrong running them leaner. Basically he said it works and the motors are still happy. If I can get e40 out of it I will be happy and call it a day!

I have never flashed my 91 oct. tune and always run the 100 fuel/tune.

Our plan, Chapman (CAP) and me, is to leave the pullies as they are now and dyno/remote tune the Stage X/100 build to get it producing as much power as it safely can on 100, and see where we are with high side fueling.

Then start to figure out what all we will have to do to produce more power with E. I'm not an E guy, but from what you're saying, it's sounding sketchy whether I can use Bandimere's pure E85 (four miles from my house @$4.00/gal.). My local station is $2.83. Bandimere's 100 u/l oct. is $8.00!

I've said from the outset that, if my Kong build works, great, but if it doesn't, a Maggie is in my future.

JSH,
I’m at the same altitude with just bolt on mods, including a JMS pump Booster and I’m flex tuned to run up to e70. Remember when these guys estimate how much ethanol content you can run, you can run more due to our altitude (10 pts higher with my mods). I’d be at e60 max at sea level. The biggest gains in running ethanol are realized when you are running e30ish to e50ish. My opinion is that it would be worth it for you to try the flex fuel kit and let your tuner see what you can safely run at our altitude.

Yea, Cody Chapman told me today he will install the kit, tune the Stage X then figure out the ethanol. It's true that translating discussions with guys near sea level is sometimes difficult. I'm also still learning about a lot of these mods.

High altitude means your making less power which is allowing you to run more E.

The Dyno SAE/STD correction factor is misleading in this situation. Compare uncorrected vs corrected numbers and you will see.

No one knows better than Denverites about power losses.

I've got an email from DynoJet saying their CF is not designed or intended to accurately correct, in my case, from Hennessey/Houston to Denver, which can be a DA difference of ~8000 ft. They said it is designed to correct between different pulls in the same shop on the same car on the same dyno. They speculated that a 6000 ft difference might be a 30% correction! This seems too high as we generally use a 20% CF.

Anyway, all of this appears to be old news to my builder/tuner, Cody Chapman, who plans to do some yet to be determined % of Eth.

What % fuel lobe does your brothers cam have?
Thinking about adding the FIC Injectors, LPE pump and a good low side system myself. Would like to run E50, but my cam lobe is only 32%. Do you think this could work?

He is running a 32% Cordes stage 2.

Love those guys, they tuned my car a couple years ago after I bolted on the 2650. Runs flawless

Cool, I should be ok then.
Thanks King!

They got a new dyno a few weeks ago.

Looks like we are both spinning the blower close to the same speed as well. I have a 5% lower and running an 80mm upper. I may be turning it a little harder.
