Hmmm, with that piping there might be enough room for the compressor as well.
Steathy!

Has there been an issue with hot air?

[Bu-Tang]

Not for me, we had some hot weeks at the tale end of summer plus 28c, noticed a little less timing but no fail safe issues

Is there a reason the controller isn't stored inside the car?

Would the flat foot shifting mod for ecutek racerom allow you to stay in boost through several gears?

The way flat foot shifting works is it opens and closes the throttle plate to maintain rpm. The problem with this while using the ESC is that the compressor is still turning and we don't have a BOV. Now, at max rpm, the ESC isn't making a heck of a lot of pressure, but it just seems (to me) that closing the throttle plate while spinning a compressor without any way to relieve the pressure might lead to problems. I say "might" because I don't know this for sure, but just to be safe I didn't include that feature (or launch control) on my ECUteck tune.

Honestly the fact that this is electric there is no waiting for getting back into boost. As soon as you get back to wot your at full boost again

Yes because the closer it us to the compressor the more boost it makes. In the electrical world when talking about 4kw everything comes into play

Sometimes I just can't help myself with my completely insane ideas....
Insane Idea #991 Mount it inside the air filter box PRE-filter so it can in no way be accidently sucked in (3m 2sided tape) ? theres room and it's a cool air charge /shrug

Thinking along those lines, how hard would it be to determine at what boost level the CELs go off and create a system that doesn't boost quite high enough to overrun the factory tables? It would obviously not make as much power as a tuned, higher boost system, but it would still be a nice bump for those who want to improve the car but don't want to tune and get nervous about faking out the ECU with voltage clamps and the like. It could be done with a bypass valve I suppose, but that would be a waste of electricity.

A bypass actually wouldn't actually waste much energy, the compressor is only going to use the amount of energy required to generate a certain pressure ratio.

A bypass is actually a neat idea because it would bleed boost in the region where the CEL triggers but would allow full boost in the higher RPM.

Then again I always look for the mechanical solution for a problem.

I think I am considering this option, but a few things still don't quite feel right. First, given the rpm limitation of this system it will only be useful up to a certain cfm. My guess is that once you bolt this on there will be minimal gains from additional mods, such as headers and exhaust. People that have already invested in na mods that gave them 20% gains might only get a fraction of what is advertised for the ESC. Again, the reason being that unlike turbos and belt driven SC, this system has a static output.

Still seems like a great system for the person that is certain it will be their only mod.

The other thing I can't wrap my brain around is why turbos and SC systems have evolved to generate the power curves which are common today. It would be possible to engineer any FI system to offer the power in a similar distribution as the ESC. Seems to me that their are practical reasons for this, and over time the user of this system would discover them.

I have no idea what I am talking about so please feel free to ignore. Also, I've read this entire thread in a single sitting and can't see straight at the moment...

interesting comment ... the low end torque/response is were this system seems to shine ... imagine a hybrid system (ESC and SC) getting the best from both worlds. That would allow a larger SC (ESC disengaging once the Large SC was at full tilt) giving higher numbers in the top half of the curve.

There is a link somewhere back at the beginning to Wild Weasel's review of the basic system. He does pretty much that exact thing. The boost chart will blow your mind.

This compressor runs full out when engaged unless in anti-restriction mode.
If it's running full out and doesn't need to be, it's wasting electricity, so I'd rather limit boost with the controller than a bypass.
