After 3+ months of prototype road and dyno testing with extraordinary results, our E55 Kompressor Cooling Upgrade Package is ready to go. Here are a few pictures of our production package. Not shown in the pictures are heat spacers that we covered in previous threads.

Some basic facts:
1. 70-80F degrees reduction in Air Charge Temperatures (ACT)
2. 15-20 RWHP gain over EVOII Power Package.
3. Heavy Duty fluid pump with 600% increase in flow.
4. Secondary Heat exchanger increases total system capacity by 65%.
5. Latest technology Kevlar hoses and AN fittings for simple and leak free installation.
6. Can be easily uninstalled, with only one cut required to a fluid line.

We will post pricing, availability and additional information early next week.

 

These guys rule. It is here and now time to make 700hp with the E55. EVO hook me up. I want the hole 9 yards we will call it the EVO X package??? EVO hook me up. These cars are going to be sick!!!!!

 

Am I correct in assuming you made the transmission cooler smaller to fit the extra heat exchanger. It looks as if the tranny cooler is below the heat exchanger. How did you determine what size pump to use. Is there a point where the pump is too large and circulates water too fast through the heat exchanger creating resistance (heat) and not allowing the water enough time in the heat exchanger to transfer it's heat.

 

tran cooler looks stock to me. system looks reasonable, hope the price is too.

 

Great news. Someone needs to get all of this and then come to the Atlanta AMG meet. We get to dyno and race so it'll be the "as definitive as possible" test of stock vs. Kleemann vs. Evosport vs. Renntech.

 

Kit looks great! Glad to see it in production.

Just a couple of questions:

1)Is the cooling circuit still shared between the supercharger's intercooler and the engine? Or have you guys separated the cooling circuits and created a dedicated circuit for just the intercooler?

2) Does the pump run all the time or is it still controlled by the ECU and turned on only when temps reach a certain level?

Thanks in advance

 

Pics look nice, but shouldn't a 70-80 degree drop in IAT (ACT) allow you to advance the timing enough to gain more than 15-20 rwhp? Or are you saying the mod will produce a 15-20 rwhp gain on its own without tweaking the ECU?

JMO, but with the current level of expense/power return on W211 mods (and I note that Evosport is certainly not the most expensive tuner out there), I have to think that someone is going to come up with a replacement blower for these cars that is more efficient and that will allow much larger power gains.

 

Since they will be selling this as a stand alone I would expect that it is 15-20 rwhp without tweaking the ECU which is AWESOME considering the car is still in stock format.

 

I hope you're right. The reason I read it the other way was he said "15-20 rwhp gain over EvoII power package," which I interpreted to mean it gave you an additional 15-20 rwhp when combined with those mods (which already include more boost, ECU tuning, headers, etc.). What you're saying would actually make more sense, because that is a heck of a drop in intake air temps, and I would think it would allow them to make a lot more than another 15-20 rwhp. I'm sure he'll clarify the issue.

 

In my opinion this mod is for consistency not additional power. While you maybe right that the cooler intake charge could let you adjust the ECU to advance the timing, this mod was not made for that purpose. It is for those of us that run our cars in different climates and conditions and experience significant performance decreases with each run.

 

Much agreement. Consistency is the real issue--Huge power delta between cold engine (not fully warmed up) power output vs. warm/hot engine power output. With a cold motor I can punch it at 70 mph and break the tires loose. Hot motor is about 30ish mph.

 

R. Range,

I thought I should also point out that you will be extremely hard pressed to find a more efficient supercharger than the stock Lysholm Kompressor this car has.

Marcus, I agree the Lysholm/Autorotor screw type blowers are very efficient, certainly much more so than an Eaton/Roots type. That is why the hot mod for the '03+ Cobras is to swap the stock Eaton blower for a Kenne Bell Autorotor, which can make lots more power. I'm wondering if a somewhat larger screw blower might be warranted here. On the other hand, if the stock blower can be spun quite a bit faster and remain fairly efficient at, say, 18-20 psi, then I'm back to wondering why someone hasn't done it yet (or if excess heat is the answer then why won't someone do it along with a charge cooling mod like the one shown here). Basically, I have yet to see anyone talking about boost increases on W211's beyond 2-3 psi, and I'm trying to figure out why.

 

Will this same setup work on CL55 or will I need different brackets?

 

R. Range,

To be honest, it's simple - no one wants to try it and blow their $30k motor... you have to understand the mentality is a lot different. A cobra guy is crazy and wants to run 9s on a stock block, the 55K cars, for the most part, just want to increase performance a little bit and still be well within the confines of their warranty.

Without this cooling upgrade, I'd be VERY wary of running anything more than 2-3psi more on a stock motor. This car @ stock boost already has some pretty significant trouble dealing with the heat.

FWIW, the C32 and SLK32 Kompressor cars ran the same blower @ 19-20psi without problems.

Let me see I can provide some answers:

1. The transmission cooler is located in the fender well, on the passenger side. You can see it's fan in the pictures. On the left. Cooler that is right behind our cooler is stock, primary heat exchanger for intercooler.

The pump we use is made for marine use and next size up from stock Bosch pump. Our main criteria is to make sure that we can get as close as we can to ambient temperature at the pump's inlet.

2. 1)Yes, we have separated intercooler circuit from engine cooling circuit.

2)Pump runs when engine is running.

There is possibly more power with more timing. However, 91 CA gas just will not let us go any further on advance.

Stock IHI kompressor is 2.2L. It should be good for 700HP (585 RWHP). What's keeping it from reaching this HP level is primarily intercooler design. Look at SLR, McLaren repositioned the intercoolers above intake ports. That motor can easily go to 700HP. Brabus already has a 660HP package.

 

Can someone post a link to the Evosport website. The link I have is no good.

Thanks

Thank you sir

 

I just scanned the evo website but didn't see the cooling system upgrade listed. Does anyone have pricing info or an exact URL.

Thank you

No pricing listed yet.

 

E55 Baller: We should have pricing up very shortly on our website. Couple of small items are still getting priced. Thank you for your patience.

 

I really look foward to pricing...

 

Vadim,

Thank you for the info. Please e-mail me at iturk182@aol.com when you get them in. I just ordered the headers & spacers from you guys. I look forward to getting the cooling upgrade.

 

Not bad ..... looks like something useful.

Interested to know the saturation characteristics.
