Yeah Active Autowerk only did NA tune for our ECUs unfortunately, otherwise there'd be another option out there as far as FI goes

I think everyone is here

Hopefully one day I'll be able to afford to have Lutz build me a stage 3 upgrade

Is there a shop as as good as lutz on custom fabrication on the west coast?

Because of the quote below (sorry for the assumption).

An air to air system can't cool below ambient either. Without doing some type of injection method, the goal of intercooling it to get back to ambient.

Anyway, my argument was based on Z4M specific setups; as in, ESS would get an additional 1-2PSI with an air to water system, etc. It's past the point of arguing any further though.

Agreed, sorry for the noise guys. Some good info in this thread so far though, I think we'll get more info once we have a few more builds with each charger. Right now we only have solid info for ESS thanks to beedub, roffle and iPhone (as well as fr8dog but he hasn't been around in a while).

ok illl throw some more ESS pro's and con's into the mix, ive gone through the various stages now and i think ill be one of the few thats had each stage for a year +, the car willl be 550 spec shortly :-)

one thing that i note about the g-power is i think they used a blower thats is absolutely in the meat of of its efficency range, so @ the boost its producing is perfect, so it makes great power, great Tq (as those asa units do anyway) BUT.... their is no room for boost upgrades with the small asa unit supplied... AITs would skyrocket.. i also like the use of a MAF in those kits.... the tune may be more adjustable.. i note from Iron AFRs are in the 12s... not very much safety margin thier by any stretch of the imagination... the s54 likes it alittle lean upto and makes great power doing so...

now VT1... great kit, but heatsoaks very quickly... i should have never brought this kit imo.... after a long day at the track it felt back to n/a again..... The ess hardware is just perfection however. The huge blower is just not even waking up out of bed at this boost level....

vt2-500, now were talking.... huge intercooler, it really is massive, huge intercooler pipework, again lovely large intake mani, really smart positioning of the BOV/BPV, and the golden opportunity of being able to use meth/water injection, the large pipe run makes it an ideal application for charge cooling not as a fuel ;-) my kit makes a solid 8psi As documented, ess this is ok and they vortech unit should make 7psi @ 7000rpm.... so i guess this makes sense??? Again the blower is still not making enough boost imo to really wake the motor up, it NEEDS 10psi... im convinced... Hence the move to 550 spec which is 9/10lbs.. interestingly this next 1/2lbs Adds MORE tq that all the other stages together.... see what i mean... Efficiency range.
i Love the quality of the ESS stuff and the way it just works, ive had my car supercharged for around 3 years now.... not once has my car been down due to a supercharger issue ( apart from a tuner issue who damaged my unit) its just as reliable as before, i can cut 1/2nd very easily. The tune, is just wonderful, it actually drives BETTER than it ever did stock, theirs no F/I feel, it feels like someone's swapped out to a v8 for you...
Cooling?? power is now much more consistent, even after all day track sessions, oil temps are kept in check by a large setrab oil cooler, its a very nice piece of the ess puzzle, engine oil temps are very tightly controlled and i love throwing death at it to see how it performs. When its really cold the 500 just feels insane, huge Tq and a huge jump in power, so i can see why the meth/water option makes so much difference.

The not so good

When you drive the car hard gas mileage is scary... it has a serious drinking issue, the blower is very very delicate, a simple pulley change done wrong made my spew its guts out all over my super clean enginebay :-(.
The intercooler pipework is hard fucking work, it needs regular tweaking and it makes the engine bay very cramped its very thick in its size, looks very cool snaking around the engine bay but its gets in the way ALOT when your working on shit. Ive personally found the ess kit needs so much tweaking to get everything perfect, its taken my along time to work out what bits touch here, what bits need to be moved ect ect...

The s54 must must must have a Catch can.... its breathes heavily and i was pretty shocked to see my very low mile car throwing lots of vapour around, a catch can really nailed that issue, blow-by causes us to loose valuable octane points, increases chance of Det and just generally makes a mess......

the #VF hardware is imo second to none, lovely stuff, i look forward to getting more info on their kits... the 570 kits would be imo the one to have as again we have that large v3 unit... the Vortech unit is quiet, reliable and easily serviceable and capable of 700hp+

so in summary which one i buy in hindsight?? Defo the g-power. if i couldnt afford the higher of the ess / VF kits, the g-power is the by far the best option IMO!! The hardware looks perfect, the tune seems good and the price is right, the added pipework of the ess kits makes them the more expensive option.

i look forward to presenting more info about my continued journey with ESS, they are a GREAT company, and have supported me from DAY one. pls excuse my poor spelling, its shit i know :-) The 550 spec adds a new FPR, New larger intercooler, new injectors / pulley and a tune... it costs around 1400GBP.

The gpower costs more than ESS vt2-500 or vf570.

I have read so many blown s54 with the VF kits yesterday on m3s. I have to post that here.
There were lawsuits involved and crap like that.

Those were the early VF kits of several years ago, when tuning was outsourced to GIAC. AFAIK they do it in house now.

Perhaps the G-Power is more than the ESS or VF kit where you are, but I'm getting my G-Power kit installed by a very high quality shop for less than the cost of the VF 480. Unbeatable deal if you ask me.

I do like how well-matched the blower is to the intended power output. My car has higher mileage than most, so I'm hesitant to run 10 psi on it. No track time though (yet).

Lastly, if you look at the hardware and numbers, the G-Power kit is running identical boost with a nearly identical setup to the VF 480 kit. I'd expect power levels to be around the same... and if anything, in favor of the G-Power kit because the blower is sized more appropriately to the setup. I will say that the VF kit I have on my 3.0i feels like it makes the claimed horsepower, as there's not much difference between my naturally aspirated M and my 3.0i.

I don't think you can go wrong with any kit.

I'm not saying VF is bad, on the contrary, I find their kit to be amazing and I am in the process of buying one for my M. However, I'm hesitating due to lack of videos, dyno, vbox, testing charts and all those threads are scaring me away and make me think again about my decision.

Some people are still having issues even after the in house tune(e46 m3), which has kept me scared of their kit :S
Even the eas vf570 z4m is still having tuning issues, I'd like to see just one z4m running strong with videos, idling, cold start, dyno, vbox and then I'm a customer all the way vf570 maf less, stage 2 directly.

the only thing that scared me Re the VF was i know for a fact Eas stop posting data as the car wasnt running properly.... maybe someone should drop them a line and ask them to chime in, the community only knows when we speak up???

Just confirmed to me that a fellow Z4M owner with VF supercharger kit in Kuwait is having issues with the tune.

Send me PM please, I am blowing cash. i don't want to blow it on the wrong place.

Afterall, satisfied customers will never shut up and dissatisfied customers will frown and kick back. I am not dumping statements to sabotage anyone, i just happen to be copying street word.

I think you of all people should know how much satisfied people will not shut up about their 8PSI pulley. you have created this little heaven in our heads called ESS and wouldn't shut up about it, that's what i call word of street and i am inclined towards ESS just because of you, roffle and a few other videos.

It would leave me to believe that VF can do the same and can probably win market share since their kit is way cheaper than ESS's.

if the VF tune isnt good how about buying and getting evolve to tune it!!! Evolve tuned a ESS s/c m3 and they got really good results... ESs leave alot on the table for a super safe tune!

they also allow data logging so you really could nail down a wonderful kit?? thats assuming the VF stuff isnt already perfect, which i have no reason to suggest its not!!

Look i have found it:
ESS VT1-445 vs stock

[IMG]http://www.**********s.com/images/Products/ESS%20Tuning/mini-ess-tuning-e46-m3-supercharger-dyno-2.jpg[/IMG]

Look at other types of superchargers like AA stage1 on and E46 M3:




Do you see how V3si coupled with ESS tune on S54 do not make any real power gain before 6000RPM? and it's almost as powerful as stock before 4500RPM.

While in the AA curve you have power and TQ everywhere?

This is a response on why i think V3si is not suitable for S54 (european high rev engine), try to use a ROTREX C38-91 supercharger on an S54 and check the curve on that, you will shit bricks I tell you. I have a guy over here in my country that has installed an S54 with this supercharger and custom tuning and intercooling and such for drift competition.

His car makes literally 350 lbs/ft on 2K RPM and upwards from that to a peak on 4700 RPM and then back to that on 8K. he drifts his car in 4th gear on some long slides, i was in the car witnessing this brutal power.

350 on 2K, fucking 350, believe that, he calls the car a catapult
