ESS Supercharger Advice

[dpohlman]

I am thinking about having IND install a supercharger on my 2009 e92 M3, and I have a few questions that I am hoping to get answered:

With DTC, what ESS version is best?

Are there any results related what the 0-60 times are for an ESS enhanced car?

What changes in driving characteristics should I expect?

Do all of the modes and functions work the same as stock?

Thank you in advance! - David

It is probably best to just call and talk to IND...... they will tell you what is best based on what you are looking for and will be able to answer all of the above questions.

Question: "With DTC, what ESS version is best?"

Answer: VT2-625 + RPI GT Race exhaust = 650HP++

Question: "What changes in driving characteristics should I expect?"

Answer:

http://www.youtube.com/embed/_OECt4wNydE <--- Russian VT2-625

http://www.youtube.com/embed/WZ1lTGmzgxs <--- Red Russian VT2-625 M3 E90 DCT.

http://www.youtube.com/embed/UV8EoXDdwA0 <--- Swedish 6-Gang Getriebe. He says 5+ car length in the end.

IND will give you the straight scoop on the kits. Everything they told me was spot on reality, no sales pitches, just straight facts. I have a VT-2 600 with 6MT and zero changes in driving characteristics. I took my 75yr old Dad to dinner in the car and it was smooth as silk. We jumped on the turnpike and I told him I was going to jump on it to show off, we were literally doing 100mph effortlessly before you knew it. Power when you want it, smooth drive ability when you don't.

I think ESS has a DCT software for those that are looking to do the VT2 600 and up. From what I understand the software is there for the added TQ ... Again I am not 100% sure and recommend you contact Roman or Nate

[Brosef]

this is my understanding:

VT2-575 is recommended for DCT cars. ESS recommends you get their DCT software for running the 600 and 625. (it's worth noting that 93+ AKI octane is required for the 625 - something to consider depending on where you live).

for cars that don't get the DCT software, ESS makes a minor tuning adjustment to the ECU that reduces the amount of torque the engine makes while shifting just slightly. I'm told it's completely imperceptable, and that it is just to reduce the amount of heat that builds up in the clutches from the added power.

driveability and functionality of everything remains the same. it should drive and feel just like stock, but much more powerful.

i would also like to know the answers to these questions, I too have a DCT and would like to know what spec (given we get the dct software) that we can run safely without any slipping, etc...

You people in the USA is so LOL on that!! In Sweden/Europe we have Shell V-Power 99 octane in our fast cars. So, I think a SKII CS 600 hp DCT with 99 octane V-Power is faster then a US VT2-625 DCT 93 octane.

I believe you are talking about 99 RON, In the US, Octane Ratings are in AKI. I believe 99 RON would be closer to 94-95 AKI.

How is the low end (<3500 rpm) characteristics compared to stock?

Jamie and Bob, thanks! I appreciate your kind words.


We really try to stick to facts when we speak with clients about modifications they're considering. It's easy to speak highly of ESS kits because the car really does work that well. Other than the almost absurd acceleration, there really is no difference in how the car operates, especially on a day to day driving level.

The VT2-575 kit is ideal for the DCT transmission. The engine's power is reduced between shifts to allow for the transmission to operate properly.

A centrifugal supercharger typically makes the square root of peak boost at half peak rpm. Peak boost is at peak rpm with a centrifugal. If peak boost is 6 psi at 8000 rpm, you are looking at about 2.5 psi at 4000 rpm and less below that. Expect very small gains on the low end. Consider other mods that might improve low end power, if any, whether instead of a centrifugal supercharger or in conjunction with it. The centrifugal actually works well with a high compression motor like the S65 by not producing much boost in the midrange where cylinder pressure is highest. You could not run as much boost with a twinscrew that would have a better low end or with a turbo that would have a better midrange, without lowering compression.

Gotcha, so the 575 would be a safe power level for the tranny. How far from "ideal" would a 625 kit be, and given the DCT software is installed as well, should we expect to run into any issues?

great post. thanks for the info

Does the SC still have a good amount of whine even at regular / cruising speeds?

somebody got an A+ in physics

I think IND would be your encyclopedia in this case. They wont bullshit you, and are not the type of company looking to make a quick buck. If anything they will talk you out of a big purchase if they feel as though it wont help or isnt smart. IND is the way to go, give em a call and you wont be dissapointed

How much slower are the 6MT cars with the ESS 575 kit than those with DCT? I need to do a search on some dyno numbers and actual 60-130 times versus theoretical ones.

the 575 isnt for the 6MT, its for DCT. 6MT guys get either 535, 600 or 625.

It was my understanding that the VT2-575 can also be used on 6MT cars. At least ESS's website claims it is.

I know that ESS recommends their DCT software for 600 and 625 but on the 575 it's optional.

?? - You sure about that? I thought Roman said that all kits are compatible with either 6MT or DCT. Difference was higher kits have DCT specific software available.
