The methanol does certainly contribute to the fueling in addition to octane enhancement but not much as one would expect since you are only injecting 1000-1300cc of meth at 100% meth injector DC. So that translates to 65-85whp worth of methanol. It's possible to squeeze the extra power from the factory fuel system alone but the fuel system hardware will be stressed harder than I feel comfortable with. Also, running straight race gas at high boost doesn't sit well with the high compression engine since it has none of the in-cylinder/IAT cooling benefits that meth does. It manages it well enough but doesn't make nearly as much power.

Unless you want to make a custom single midpipe/cat-back, you will need to go with the Y-style downpipe option. The single pipe option is for those who want to build a custom exhaust for weight saving purposes. No need fuel dual piping if you only have one turbo!

If the Single DP piece isn't used for those with stock or aftermarket dual exhaust can we choose the option to not include the single dp and just use that credit toward the Y pipe?

Also, are the prices limited time or are those the regular pricing? And were those dynos with the optional ball bearing turbo or just the regular CEA turbo included in your starting kits.

You don't need a Single Turbo during winter, or XI when roads are cleared from ice

The DME reflash was a added to the kit recently after we started doing more 6AT work. With it, we found a way to get more positive shifting performance at high boost. It works very well in conjunction with the specialized firmware we wrote for the Procede which drops boost for a fraction of a second during manual/paddle upshifts. It feels far cleaner/more stress-free on the transmission than short-shifting an traditional FBO 6AT car.

While we were in there, we are also some other changes which allows the Procede to do what it is so good at. We clean up the ignition mapping, change the load targets slightly and modify the AFR target table which means we don't have to apply as much (or any) wideband bias. The upside for that is that logged AFR values are now actual, not "corrected". The massaged timing tables provide more timing stability which is important at these higher power levels. With the underlying tune cleaned up nicely, the Procede doesn't have to fix much. Instead it just focuses on the fun stuff: boost, throttle, methanol, ignition control/failsafes. And it does this stuff very well.

Hope that answers your questions.

Cheers,
shiv

What I'm getting at more so, is asking you if you plan to run 50/50 on the 62 eventually shiv, to see where that will put things as well?
No immediate plans to run e85 mixes on the single turbo. But down the line, I expect that to be an option. For flow limited twin turbos, e85 mixes tend to improve power/consistency a bit. For the single turbo set up, the 58/62mm is not working very hard which makes the entire system a lot more stable/thermally managed. Making e85 less effective.

What should be done if one lives in Europe(ME ).
Another thing is, i live in Germany and we have no speedlimits on the autobahn, for how long can i floor this car without being in the risk zone ?
Check my sig and you'll see what i mean about flooring a car!

By the way, NICE KIT!

This is great! Now I have a question, I have an Automatic 335i and have added over the last year multiple parts to the car such as BOV, Charger Pipe (ER), FMIC (ER), Vanguard Exhaust, JB4, Devils Own Meth Kit. Now what will I be able to keep on the car? and the reason why I ask is because I am truly leaning towards getting the single turbo and want to make sure that I sell what I will not need.
Thanks and great job at conquering the single turbo.

It's really hard to know what the engine can withstand in terms of sustained full load/max speed operation with over 700bhp. One thing for sure is that you will hit that speed helluva lot faster I think we will be implementing some time based limits that will prevent this kind of undue stress. Perhaps give the user up to 20 second of full power and then drop boost down to 15psi (which is still well over 450whp).

Judging by the list of mods, you can keep the exhaust, charge pipe and bov. You can possibly keep the meth pump in your DO kit. But I'd highly recommend that you with the new 1.5GPH pump that we use. It comes with compression fittings which are a lot more secure than push-on fittings. Thanks for the kind words

Props for this.

All of this makes a lot of sense.

E.g. this gets rid of starting the biasing close to the ceiling when there is the risk to hit it.

It should be another way around on this Y-midpipe option. The single midpipe should be an option for those who want to convert thier Y-midpipe to single midpipe/exhaust. Most of us here have Y-midpipe on stock and aftermarket exhausts...

Cummon...lets keep the price down a bit, Shiv!

I was thinking the same thing.

I think we should have the option with the starter kit to either go with single dp or y pipe dp for those ppl that want a single exhaust sytem or dual setup.

You can certainly do that too. We will provide the mating v-band flange for the single 3" downpipe. You can then modify your mid pipe to merge into a 3" Y and mate with the single turbo dowpipe.

Ok so it sounds like you have the ability to reflash the DME
I am guessing in addition to this list i would need downpipes and exhaust ?

Thanks for the clarification on the flash, now the only question is - Redskins season tickets or single turbo upgrade?
