Just bought a 01 E55 this week and am planning on modifying it come March. I passed on getting a W211 E55 because I want a track toy as well, so a clean 01' it was, later I will get a nice Z06 in addition.

I am starting this thread in hopes of having one thread that helps identify who's Kit is the Best in Performance, Best in Value, and as well, Best in Durability/Reliability.

What I am looking for is SOLID INFORMATION on Super Charger kits available. Time slips are the prefered data, but other means of measurement are acceptable.

I know there are different MB camps whether it be "pro" Kleemann or "pro" HPS, so this thread isn't about arguing the design merits of either kit. (BTW, I am looking for info on the "New" HPS kit with the updated S/C'er, but older model data is welcome as well.)

This is a chance for the Tuner shops to post their own best data as well as Customer car data.

So down to the numbers, what are the typical as well as best 0-60 and 1/4 mile times.

Lets start with stock like my car is.

Best Times for a stock E55 = ???
Best Times for a Kleemann E55 = ???
Best Times for a HPS E55 = ???

Note: I realize that every car out there is a little different in setup and modifications, so please post car details as well so they can be taken into consideration.
Along the same lines, it is realized in advance that track differences can skew the results, differences can be taken into consideration as well.

I look forward to maximum participation.

you may want to try the performance fourm as well

Fast55

I will have dyno numbers on my 55 sometime after the first. It should be complete about that time and will be run before and after for a real comparison. I will post the graphs once I have them. It may be a while before I get the opportunity to run it for time, but that is planned as well.

RossN

Cool...

Which kit do you have?

I am after times as they are what counts when you are lined up on the street, not that I street race or anything.

Fast55

2nd Gen HPS. It should make comparable power to the Kleeman or Renntech setups. I have never seen a dyno graph on a Kleeman or Renntech car. I'm expecting 500-550 HP at the crank, which is in line with their claims. I have seen a Renntech 55 make an 11.86 sec. pass on street tires!

RossN

11.86, very nice! And not even drag radials?

Is the second Gen HPS Intercooled, that would of course be the prefered way to S/C any motor.

Can't wait to see your test results Fast55, this should be good.

You going to get LSD as well? I am beginning to wonder if it is safe WITHOUT it.

Fast55

I believe that car did have a LSD, but was on street tires. I've considered it, but the cost is out of line. I'm going to wait to see how well the stock ESP software deals with it, on and "off". If it's really bad, I'll bite the bullet and get the diff.

James F. Cannon

No LSD on my W210 E55, stock differential. Street tires are Bridgestone RE050's rear size 285/30-19's.

JAYCL600

James,
How do your 285's fit in the rear...I just ordered 275's for a 19x10 rear in fear of rubbing...what size rear wheel do you have? Thanks.

jason

James F. Cannon

Rear wheels are 19 x 10 Carlsson 2/5's. I originally had a problem with rubbing on the inside of the wheel well but RENNtech adjusted the offset to resolve the issue. The outer edge of the tire sidewall protrudes slightly beyond the fender but I don't mind. I did not want to have my fenders rolled just to go a size wider on my tires.

Fast55

So James,
No LSD on that run? Overall, how does the car (ESP)react to the HP? Any other mods beyond the Renntech blower?

RossN

James,

What boost level is your setup running, any internal engine mods?

James F. Cannon

The car hooks up pretty well on the drag strip but on the street I have to feather the throttle in first gear and avoid full throttle downshifts to first. I get some tire spin with kick downs to second but it is manageable. Boost is 1 bar so other mods were needed. The RENNtech high pressure supercharger modification included low compression pistons, forged conn rods, etc. Also installed headers, downpipes, etc. for free flowing exhaust. Later did a cam change and now have 463 RWHP. I really don't know if the LSD would help improve quarter mile times!

Fast55

I don't think there's any question a LSD would help. Even my 430 with the Gen 1 HPS system could've used some help. Didn't know you had all that. I'm hoping for a little over 400 RWHP. That should be about the same HP as a stock W211, so I'm thinking low 12's (11.9's?? ) shouldn't be a problem. I will be changing the tires to 285/35 18 and 245/40 18 F1's on the Monoblocks and (maybe) ditching the resonator along with K&N filters. Beyond that, the diff. has made noticeable improvements on the W211's, so I'm sure your car would benefit.
Was all this done when you made the 11.86 pass? Would give plenty to see and ride in that sled!

RossN

The whole shebang! Very nice. I agree with Fast55, the LSD could only help. And a lower gear.......

vraa

Ya know, the first thing that went through my head was Mr. Cannon's cars after seeing his runs Pocholin recorded with his camera.

Mr. Cannon, you are my idol.

RossN

vraa,

Any link to info, is there video???

vraa

There are many videos, however my computers been dead for a while but I'll try to ask Pocholin if he still has them on his computer.

vraa

As a side note, I'm pro Kleemann because not just the supercharger itself, but the team behind them and the guys that sell + install the supercharger are a blast to talk to and work with.

RossN

Thanks vraa.

vraa

No problem, I went ahead and PMed Pocholin the link to this thread and I asked him if he still had the videos. They are really nice! I think you'll like them.

Chappy

James, I enjoyed seeing your E55 duke it out with the locals that day in Georgia

Have they let you back on your local track (sans cage) now that your running 11s? BTW, thanks for helping to "blaze the trail" at Silver Dollar....they don't kid us anymore when the AMGs show up for a track day

James F. Cannon

Before the cam change my best was 12.105@118.3 MPH. Chappy, I wish I could have been there to see the SL65 run!! And yes, they let me run at NPR but I have to run alone (no grudges)!

Chappy

No bull for sure. That thing FLIES...it was the fastest car at the track at the last outing.

Till next time....
