E85 + stock turbos?
I'm considering what to upgrade next on my car, and thinking I might add e85 tune. What type of numbers do people see on stock vtgs with e85?
The car has a europipe and an apr tune which would be replaced by Todd's e85 tune. It is in the low 500s power now based on runs I've mave vs other cars. |

Dallas Tx. There is an e85 station close by me. Proto is 8 hours away so I'd have the work done remotely, no field trips to northern Arkansas for me :-)
We get real e85 about half the year, e70 the other half. Lots of local evo and gtr guys run e85 all year, and Todd told me the ecu will adjust between e70 and 85 on its own. |
Can you simply change over and run E85 with nothing more then a tune ?
|
Good post/question. I'd say your gains would be considerable, especially if you normally run a 91 or 93 octane tune. I run a 100 octane Proto tune and also am interested in e85. It'd be interesting to know if anyone has encountered any long term negative effects running the e85 for a few years with the stock fuel system. (w the exception of larger injectors). Plan on adding the larger injectors for the additional required fuel unless Todd told you otherwise. Post results if you end up doing it. GL

I run a E85 Proto tune & had the regular Proto tune before & can tell you it's like running 100 oct or even Ms109 for $3.50 a gal instead of $15.00 a gal,i've been running it for about 3 yrs straight with no problems at all.I have upgraded 63.5 vtg's & only did the injectors ( 83 lbs) but can tell you, it wants even more gas to maximize the E85 so you need to upgrade the whole fuel system for maximum gains.If you have a station close by like me it's a no brainer you can run regular gas in a pinch no problem, just don't hit boost.

twturbo,
Has your car been on a dyno? Or any 60-130 times? I might add the injectors like you said, but it seems with all the labor to swap injectors, the turbos need to come out too so might as well swap them at the same time. It might be nicer to my wife if I did the tune first, the injectors/turbos and retune later.. :-) |
Nothing current but soon as it's going in for some other stuff & needs the tune recalibrated for my new push through y-pipe & check with Todd but i believe you get several recalibrations with his tune so you can change to an e85 tune down the road like i did.
|
If I get a tune it would be e85 - the car has an APR pump gas tune on it now, and it hauls. I just wonder if theres another 50whp left in the stock turbos on e85, or if I should just switch to the proto 65mm vtgs now +e85 to get well into the 600-650 range. Harder to convince the wife I need to drop 7k to do it all together than to do it half and half if there's big gains to be made on the stock turbos :-)

The best posted numbers with APR tune match or even exceed that with upgraded vtgs so I wonder how much improvement you will notice with E85 vs APR tune. |
Pbox is actually ordered, I'll get numbers in the next few weeks
Apr is an aggressive tune, but it can't Run the timing numbers e85 allows. It is 18+ psi, but timing isn't 17+ at higher rpms. |
i've heard that with the right ecm with flex fuel sensor you can gain close to 100 lbs of torque and u don't have to worry about running out of e85 as the ecm automatically adjust your parameters stock turbos and injectors. There's a guy in Texas who does this for a living. He's got some great accomplishments under his belt.

MattM6 I'm wondering the same thing...
Also wondering what is the best "bang" for your buck. E85 tune + what else If I were to decide to do a tune + turbos what is the best setup out there and what does it cost ? |
Pro Efi ecm with flex fuel install it once and it can support whatever mods you do in the future without limits. It did managed the fuel system of the Venom GT when it broke the world record 2-3 months ago and was on the blue Vette that cleaned up the house in Texas last year against a 1400 hp GTR?. No limit on its capability. I'm using it for my 1000 hp build for my 03 996 tt.

I have e85 plus all bolt ons and modded vtgs by protomotive.. The car made 620hp on a mainline dyno. If anyone knows dynos...This is the heatbreaker of all Dynos. They say add 18% and its equivalent to a dyno jet.. That means my car would be 731.6 awhp on a dyno jet.. The car also trapped 136.7 mph in the qtr.
Fuel system is adequate for this set up with 85lb injectors. For most people that would be good enough, but I am selling the vtgs and adding gt30s. stay tuned..... :D |
pbox
sorry too thread jack im looking for a pbox were did u get yours . pm please
e 85 is the stuff 65 hp on modfied challenger on race gas . |

63.5

Vicious, when are you taking off your turbos and going GT30? Why GT and not alphas? And..... PM me what you'd want for them :-)

Went ahead and had ToddK put a 93 tune and e85 tune together for me along with .2 intercoolers. 93 tune is nice, not quite as aggressive as the APR but thats a good thing. The E85 tune works on stock injectors, stock FPR, and it HAULS. I can break tires loose any time I want to up to about 100mph. Can't wait to put on bigger VTGs and keep pushing onward. I figure I'll be satisfied with 80lb injectors and 65mm vtgs on e85. Good 700whp there.
|
Are you using fenderwell intakes? Why did you choose .2 intercoolers over after-market ones?
|
Stock intake.
.2 IC because all research I've seen of IAT and such by forum members shows nothing beating the .2s. Champion ICs might be nicer, but they've refused to release IAT test data for 2 years, so I refuse to give them business. |
Do properly do an E85 tune it sounds like one needs to:
ECM tune (APR?) Upgrade injectors Exhaust VTG's to 63.5 or 65 .2 Intercoolers (or is that not necessary) Clutch? (is stock clutch able to handle the additional power) Ballpark what the total cost of this for me. |
There's two options with e85.
550-600whp: Call this 10k or so all in Clutch (any tune will require a clutch) Tune (only protomotive or switzer can do e85. I replaced my APR with protomotive) Exhaust ~700whp: Additional $3-4k to the above depending on vtg selected and labor rate VTG Injectors Intercoolers would be an upgrade I'd do regardless of tuning or not. The .1ICs just plain suck. |
Continuing down the path of adding power - some packages are arriving early this week.
1) BBI Coils + plugs 2) Protomotive injectors 3) Protomotive 67mm VTGs 4) Front sway bar to resolve some oversteer issues I've had on track All will be on the car this week and we'll be good to rip onward. I'll post new 60-130 times as soon as they're available. Expecting large gains in power over stock turbo+e85 as I was out of injector and thus only running 15psi from 5k onwards. |
[QUOTE=Chkmgnt59;3812785]Went ahead and had ToddK put a 93 tune and e85 tune together for me
So did Todd k figure out how to do this & how are you switching tunes ? ,i requested this but i've got one of his 1st E85 tunes & back then he hadn't figured it out yet ,i'm going to be doing a recalibration soon for an added mod.I currently can run regular gas if needed but without boosting & what size injectors are you going with. |
80# injectors. And no on-the-fly switching, I just have different maps that I can plug in and change using my laptop. Ideally I'd love a cobb accessport-type device (note to cobb- build one for porshce..) that could swap maps without a laptop, but its not available yet.
|
Ok thanks & i know i can do the same ,but yes a switch would be great.

Specifically what I'm interested in is not having to hack up the existing ducting or use zip ties as I've seen most of the 996 installs do. Does anyone have any suggestions here? Thanks, Dan |

No typo, Todd has just released his new 67mm vtgs, replacing his 65mm.
My car is all put back together with the initial tune on it. Haven't been able to do any real logging yet, but from what I can see, we have lots of headroom to turn it up. only 75%IDC on the initial map. |
oooooooh I see...time to send him an email.

Wow time flies.. so we've been doing some testing back and forth and logs just weren't doing what we wanted them to do. Points to a boost leak, but we couldn't find one here at my shop. Other option was perhaps a bad set of turbos. So after some emails back and forth and talking w/ the shop here and Todd, I decided it would just be easier to get the car into Todd's hands. So I dropped it off with him this past saturday, and he's checking it all out and will return her all buttoned up. Looking forward to getting it back (no timeline on that). Todd has been very supportive and opened up his schedule to allow me to bring the car to him - great overall experience.
