The only correct layout with this car and our kit IMHO is a properly designed Air/Water manifold. It will be to much modification required to fit proper FMIC and pressure drop will be much higher than manifold aftercooler due to complex airpath and a lot of air moving through it to feed the beast.
A properly designed manifold/aftercooler will work extremely well on this car, it is just a question if the market will support the R&D costs of one.
Yeah, it's a trade-off between the ultimate efficiency of a water system (i.e. under continuous heavy duty cycle conditions such a tracking) at quasi-steady state versus and air-air and its drawbacks as you noted. In any event, as much as I'd like to say otherwise, I'm betting your gut already knows the answer about net income from a custom aftercooler manifold ever even breaking even for S62 systems, sadly.
with an air water cooling system, i assume the water used is from the engine cooling sysmtem (apologies if that is wrong), which will be running around 90 degress. so Rom3n/asbjorn, can you tell me what the temperature increase is through the SC?
I cannot believe that the low pressure you are running would cause an temperature increase of 60+ degress (although i am speculating). and if the increase is below that, there will be no point in having an IC
Yes I did. ESS tuned my car during the 1st week of May (I picked it up on May 2nd at Bimmerfest). Headers just went on 3 weeks ago....new "header software" version went in about 100 miles ago. Adaptation is still ongoing.
The power increase was DEFINITELY noticeable...obviously not as noticeable as the change from stocl to FI...but noticeable nontheless.
I think the key word here is easily. A stock E39 M5 with ESS SC, I suspect it would start to pull away from an E60 at speed (maybe >120mph). Now with headers, i think it can do it easily. Just my thoughts.
I always assume we're talking a rolling start race, where *one would assume* that the ESS E39 would cleanly pull away from a stock E60.. not talking bus lengths or anything. From a dig I guess it's a driver's race?
from a roll I don't see how an E60 can keep up, SMG or not. From a dig it'd be interesting since both cars have their problems down low (E60's have less torque but E39 SC has too much torque) but once the E39 hooked up, I think it'd reel in the E60 and eventually pass it.
That's great to hear about the DSC re-tuning. You guys should advertise that as a feature of your kit, it may be a selling point for guys who wish they had LC. Should put a frown on many an AMG owner's face as all they see is E39 rear end...
Can someone please explain to me why the S2 increases torque by about 50 ft-lbs while the ESS reduces torque by about 50 ft-lbs at 2000 rpm? Or, for that matter, just explain why the ESS decreases torque by 50 ft-lbs relative to stock.

It is not in the final production software, in the initial R&D software we set vanos very conservative in the low RPM range (below 2500). This has later been optimized. If you pair the SC kit with a set of good headers you will make more tq than stock even at 2K.
AJ, can you please specify exactly what tunes you guys have done for the VT550 kit? I know you have basic, headers, and meth tunes. Anything else?
Separately, I know you have a T-trim upgrade option. Can you specify exactly what that includes and costs and what other upgrade options ESS has for the VT550 kit, even if "unofficial"? Thanks.

You pretty much nailed it there. We have stock, headers, and meth/race fuel tunes and we can offer the T trim blower for those looking to go above 775HP in a custom configuration. T-trim option is USD 1500
so it turns out that my V12 clutch kit is actually a 540i kit not a M5, the dowel sleeves and the missing teeth dont line up. here are images of the goods, you will see how off they are when a align both dowel sleeves on each flywheel, and what the bolts should look like if the missing teeth on the side are aligned.
taking donations for a V12 M5 flywheel...its for a good cause.
