E30 vs E0 + booster is probably 10-15 hp higher agree?

Depends on the octane booster and tuning. If the octane booster is good it's the same as E30.

Found an e85 tuning site that says 5% for e85 with no changes in tuning. So e30 is more like 5-10 hp for us. Still free hp.

Unfortunately it just tanks your gas mileage, lol

Ethanol (and meoh) have a very high specific heat of evaporation compared to gas for example. This means they pull a significant amount of energy (in the form of heat)when they evaporate. Running high ethanol blends in a gdi engine produces great results due to the fact that the ethanol is injected directly in the cylinder and significantly reduces the temp where it is most important due to the cooling effect of the evaporation. This is one of the big benefits of gdi after all it's just alcohols amplify this effect significantly compared to regular gas. This is above and beyond the octane benefits observed by PI applications of ethanol.

I come from the mazdaspeed community where it was pretty well accepted that anything g over ~e30 was basically enough to completely eliminate knock (for better or worse) Lots of people where street tuning g with Cobb and it was shown again and again that you could.push timing past MBT without seeing knock when running high ethanol blends.

In general if running a high enough ethanol blend (as long as you dont run out of fuel) you should see very little difference vs wmi in most situations imo. I think some of the data from Terry and get stung support that. The biggest thing is you cant just say wmi adds this hp or e30 adds that. They both allow for pushing g the boost and timing higher but ultimately there are limits in how we can currently tune and how far you can actually push. Adding wmi to a car running e30 and already maxing boost and timing is not going to do much. Or vice versa with running a bunch of e and wmi.

Thanks Tonka! Maybe we should switch Jesse P's time to Map 2 so it doesnt confuse anyone else. Going forward people will refer to map 0 as stock, Map 1 as 91 octane, Map 2 as 93 octane and Map 3 as Meth map.

Ran this past weekend for opening test and tune lots of breakdowns and I got there late so only got in 3 passes. Ran first time with just the JB4 set to map 5. 13.16 @ 108 mph was the best time i could put up. That best time came also at the worst time of the day for the DA 7,900'... also ran it with the draggy to see how far off it was it was fairly close in all metrics. Look how close of a run against a ECU tuned 2015 335i X drive was !


I was hoping for 12.9 in the 1/4 mile with map 5. I will try again this weekend in the morning.
How the hell do i get that 60' down ?? I cant seem to get anything less then 2.13-60' even with map 5 ????
Im running GT AWD using Launch Control. Mods: JB4 W obd cable with denso spark plugs and E30.

 

[brancky3]

You're at a hell of a disadvantage with that DA

 

[Tonkabob]

Agree. I think that 60 foot is in line with your 13 second run and caused by that huge DA. Just got to make more power.

Not bad, but yeah your 60' is killing you. That's worse that most RWD Stingers and any AWD should easily be running 1.9s at least. Were you spinning the tires at launch? All seasons or Summers? Did you try the Boost-by-gear(BBG) setting in 1st and/or 2nd gears?

Maybe try DIY intakes as your giving up ~20whp with the restrictive stock airbox, especially at higher boost levels like Map5.

Ive be thinking of going down the intake route anyhow this is the push needed to go in that direction.

No detectable wheel spin at launch for any run, the car is on the stock 18" bridgestone potenza all season tires. I didn't mess with boost by gear yet. Does BBG allow for more boost to help launch harder because it launches pretty soft right now no matter the map. I thought BBG would only limit psi.

Boost by gear reduces PSI by a set amount to reduce wheel spin. If you aren't having traction issues you shouldn't use it. But are you sure you're not having traction issues?

Yeah 100% sure it wasn't losing traction from wheel spin. I stuck my gopro on the side of the car pointing at the drivers side rear to check with slow motion. Took off straight as an arrow no fuss just slow.... 60'.

I just looked up what map-6 is for might try that this weekend to increase boost in first gear opposite of what RWD guys are doing see if I can find the tipping point of traction for the my awd car.

Even at a prepped track I get wheelspin sometimes....sooo your 0 to 60 is slow and you have no wheelspin cause you aint making any HP.....the high altitude has got ya by the turbos Wash

I'm doing AWD 1.83 60 foot on the street and track with no wheel spin so you have lots of room still.

 

[Revvdmedia]

I think what would benefit us AWD guys is a tune that takes full advantage of the AWD with an aggressive launch. Look at a car like the Audi RS3 and how it launches, and achieves a 3.6s 0-60. I'm sure our car pushing the HP/TQ that we are at tuned combined with a hard launch control would be damn quick.

 

[washguy]

ooopsies Brian went back and read you got AWD.....nope you shouldn't have much wheel spin if any...BUT the high altitude has got ya.....sea level up to 700 feet you should be under 2 seconds with your set up for the 0 to 60 Wash

Tonkabob is already running 3.6s 0-60 times and that’s only with 2450rpm LC runs. When a TCU tune comes out with boost building at launch we will be in low 3s 0-60 and all the RWD Stinger owners will sell theirs to get an AWD version!

I think you're failing to understand what impact elevation has on forced induction cars. A stock RWD GT at ~sea level will run a 12.9, this has been proven. At Brian B's elevation the exact same car will probably run a 13.7.
