E85 and stg 3 Magnuson

[Boris]

I'm convinced this is the ticket. It came to me last night as I was taking a dump.

The magnuson unit seems to be trapping 124 consistently with race fuel, but who drives around with race gas as a commuter. E85 runs cooler too doesnt it?

Does anyone know anyone that has done this?

[4RCFED]

Haven't seen any numbers/logs on it. There's only a handful of people running the bigger blower I think.

[chaos2984]

Their is no try. Their is do or do not.

But only a 2mph bump from full out Stage 2+ to a Stage 3 seems lame to me.

Its not that it runs cooler per say. Just E85 has a higher octane rating so its more resistant to knock or detonation.

Only one Magnuson car trapped 124mph, I wouldn't call that consistently, and I don't believe it was even reported that it did it consistently as they only posted their best time.

Agreed,

I'm 1.81mph below in overall 1/4mile traps, and I'm on stock cooling, full weight, and ran in D/A's that were approx 1,148ft higher.
Primtime is trapping 1.12mph below in overall 1/4mile traps in D/A's that were approx. 556ft higher.

But then again, it's hard to compare numbers from different tracks on different days and different testing environments. I hope there is continued development on the stage III blowers, I would like to see solid and consistent 10's from the platform.

E85... has ALWAYS been the answer... whether Stage 1/2/3... but there's little to no support for it and it will require additional hardware.

There have been companies that have posted "teasers" of E85 support with flex fuel sensors attached at the fuel rail. This would absolutely solve most issues with heat.

I wouldn't be surprised if you see within the year multiple companies that come out with a dual pulley tune/full e85 support with a fuel pump and flex fuel sensor. Based on EPL's posts we could all expect big gains off both at Stage 2+ levels and who knows with the tvs1740.

Also APR has still teased that they are working on "other" solutions for the 3.0T which could be anything.. possible a turbocharger conversion.. which would probably produce more power for less than the Magnuson Blower.

i mentioned thinking about E85 to a buddy of mine who works at a local tuner shop here. he did me a favor and called APR and asked them if they have anything in the works with E85 which they did answer "yes, and they're working on it" but didn't give any time frame or details.

After accessing the hardware on pump fuel, we've decide not to support the 1740 blower with a software/upgraded hardware solution.

A few weeks ago I called APR and they said they weren't working on a dual pulley, or E85 solution. An APR solution is a hope, EPL's solution is real, and a phone call away.

Good choice because the 1740 is a complete waste on this platform.

[andthen]

I'm pretty sure I'm maxing the injectors on E85 dual pulley. So there's that to consider..and with Direct injection it won't help IAT at all.

I drive around with race fuel for much of the summer. I work from home so a tank lasts me 3 weeks.

[TexasDfwS4]

Work from FTW. but the race fuel is costly none the less. E85 will be the winner for sure but is this platform able to handle it. everything is electronic so we depend on the tuners for the right adjustments and some cars are not the same... i.e.. some cars burn oil so this and other issues can change the performance and at the top end of this platform anything makes the difference even the spark plugs lol.

[Dudemans4]

Let's just put a cobra blower on the car an m112 would do the trick lol

I do wonder about the S/C intercooler health long-term with a dual-pulley set-up though. I know an upgraded cooling will help, but I would love to know the delta between a stage III versus a stage II DP in outlet S/C intercooler temps.

something to think about in terms of reliability because I have searched and found some cases of them leaking even on stock level boost. However, our stock S/C intercoolers are cheap and as easy as removing the S/C itself to replace, which others have stated is like an hour job.

I walked one pump for pump.... Posted the video a few weeks back. APR stage 3 with all the supporting hardware. Same tune that supposedly made 477whp

[joediesel]

someone make an adapter for a whipple!

Are you blending E85 and 93, or running straight E85 on that GIAC stage 2?

[CELison]

E38

[Loe]

E38

Loving that you are continually testing this mix as well, its such a perfect mixture!

[CELison]

For sure.

[audistealth]

E38

Does that assume shell 93 is 10% ethanol, and is that on the normal stage 2 tune? Just curious.

Yes. And it's on the race gas file.

[audistealth]

Yes. And it's on the race gas file.

No knock or timing retard on the 100 file? VERY interesting. I should pay more attention here again.

[mrmomo313]

VERY interesting. I should pay more attention here again.

Indeed. Loe ran 11.2 @ 122 on a similar 93/e85 mix on GIACs race file stacked with the CW pro box. From the logs I've seen, his car makes excellent timing and pretty much no knock corrections in good conditions.

[Dubious]

What is the ratio of 93 to E85 to acheive the E38?
This is handled ok by stock FP?

I mixed my first tank last fill and went conservative with 2 gallons E85 rest93 on empty tank.

TIA!

Only one Magnuson car trapped 124mph, I wouldn't call that consistently, and I don't believe it was even reported that it did it consistently as they only posted their best time.

it's true, this thread is my shameless attempt to reinvigorate the discussion regarding higher power for us via e85. I just still can't believe the stg3 is such a monumental flop. All that time and then nothing.


How are you and the other guy trapping 122 when everyone else seems to hover around 117-116 with similar altitudes?! I want 122. Id be happy with my car consistently above 120 mph- mind you this is not a track toy for me, but just using the 120 mph trap to gauge overall power.

dual-pulley set-ups with either specific or a combination of non-specific hardware/software to support it. I'm on GIAC stage II + Chipwerke Pro, primetime is on a dual-pulley specific APR file. Mind you that me and him could also improve our times and 1/4 mile traps as well, so our current results may go up by years end.

There are two others also trap over 120mph, one is dual-pulley without running supporting software for it (Jones2012S4 GIAC stage II, 121.26mph), while the other one is a single pulley car (Auditude 2.0t GIAC stage II, 120.03mph).

I have a feeling two or three more APR cars, and possibly two more GIAC cars will join the 120+mph group in the near future as well, just a prediction

Sure does

Here is a log from my slower 11.2x times --> https://drive.google.com/file/d/0OTN...ew?usp=sharing
Also shows the behavior of the engine during the LC sequence

[ALAN12186]

I should be running my setup in the coming weeks hopefully I can join the club

[MaGomes92]

seems to be a lot of dual pulley cars on the streets now. Anyone ever pop one of these motors ? i don't care about the blower as it seems they are a dime a dozen.

[Silverbullet S4]

...called APR and asked them if they have anything in the works with E85 which they did answer "yes, and they're working on it" but didn't give any time frame or details.

That's been the answer for "TWO WEEKS". My shop in the Springs is supposedly in tight with the tuners at APR (allegedly helped them with the last stage II update and some skunk works A4 stuff that will beat our S4s) and they said they have nothing currently in the works "and probably won't" for the current gen S4s. Who knows....

[joediesel]

Dual pulley + e85 + nitrous + upgraded dsg clutches = Low 10s?. I dont know what the bottom end can handle

Slicks would be nice too
