To be honest. I've been giving them a lot of chances to get it right but this last round thorougly pissed me off! They cooked up some crock of Sh*^t about how I was their best customer and were going to give me even more power with some additional "tricks up his sleeve" if I left the car with them for ANOTHER week. Hell they even got me excited about the new Magnuson Blower they were putting in my car in June that will pump out over 450whp without any other mods.

When I got the car back they just told me it was running fine and needed NOTHING when in reality I suspect that they were USING my car to test something (FMU?) to replace the costly ECU programming that Jessie is doing and wanted to see if it would work on a newer model AMG. He said the only remaining improvement opportunity was the "transmission slippage" but that HPS is out of money and he's not going to wrap $1,000 bills around each kit they sell. They returned my car even dirtier than when I left it with them. Not even the courtesy of washing it after borrowing it for free and driving it back and forth from LA to Escondido (200+ miles each trip) and Dyno'ing the Hell out my engine for 8 days.

HPS tells me that I'm their partner and friend yet they continually try to take advantage of me. Now they're trying to censor me and when that didn't work they try to bribe me. Well I can't be bought and will stand by my principles. I owe it to the Benz enthusiast public to tell it like it is.

They tell me that the fake dyno sent to me was an innocent mistake. Well how can both Bill and Adam talk about the numbers as being the one of the best they ever had? They can't claim ignorance when they openingly boasted about how good my numbers were. Only Jim did not claim that the 414whp was real and said he did not remember ever seeing that number when dynoing my car at his shop shortly after the blower install back in November.

If they are'nt straight up with me and use bully techniques then this is what they get! If they threaten to void my warranty if my car breaks. So what? I won't be filing a warranty claim but instead a legal claim!!!!

 

Oooooooo so scary!!!!!!!!!!!!I'd pay to see that!!!!!!!Too fuken funny!!!!!!!!!!!!!!!!!

 

EXCELLENT POST MAN!!

 

Watch out foo, I heard he's 6'4" with 3% bodyfat.

 

Yup, and 150 pounds.

 

Not a great turnout. Believe it or not 3 HPS cars showed up and 0 Kleemann and 0 Rennech cars and 1 HOP car. It turned out to be an HPS duel between Gen I against Gen II. Guess which won? One Gen II died after drag strip take-off and another made less horsepower than the Gen I. You could say that Gen I's may be selling strong but Gen II's are heading for the graveyard.

How can a blower that makes 7.5 lbs of boost make 6rwhp less than a blower with only 4.5 lbs of boost? The answer must lie in the faulty design of the Gen II. The flaw is not in the Eaton/Magnuson blower because Corvettes, Cadillacs and Mustangs all get an additional 150-200bhp (Check out dynos at MagnusonProducts.com) but in the design of the intake manifold of the Gen II. My conclusion is that air and water flow is just TOO restricted with the Gen II. I don't think the greatest ECU tuner in the world can do much to improve the power and efficiency of this Gen II. Time for a Kleemann!!!!!!!!

 

Ok we will all hold you to this. It was good to finally meet you yesterday and just talk about what ever. You are a great guy and I hope you get your HPS drama put to bed and that you get your Kleemann real soon.
Too bad more cars didn't show up but I guess that is human nature to say, "I will be there", but then flake. I think the only way I will get more HP out of my car is headers and Aquamist because my little blower is maxed out, but 367whp isn't too bad for a 4.5psi and only cost $4000 .
Keep us posted on what you are going to do and when.
Mario

 

Any pictures from the meet?

 

Here is my dyno from "Dyno Day" 4.5psi!

 

I apologize for any hurtfull remarks I may have made that were directed at Adam F. Furthermore my previous comments pertaining to the HPS supercharger are my ACTUAL EXPERIENCES, Maybe other peoples experiences will vary.

I will not retract any previous statements on the product line and the problems that have insued after Professional install on my perfectly maintained vehicle that had an extremely healthy pre-install 220rwhp dyno from the installer Mechtech, everything I've posted on that matter stands as is, all accounts of my experiences w/the hps gen II supercharger are 100% true this will be my last post on any related concerns w/HPS period!

My Lawyer has instructed me to write this post.

 

Mario didnt you have 315 or 325 WHP before w/ the powerchip and evosport pullies?

 

According to Powerchip I went from 295whp/310wtq to 310whp/324wtq. This is a 15whp gain but I never really felt it. I often wondered if I really gained anything from Powerchip. I have seen dyno's where cars have lost power after software was installed.
Before I added the supercharger I removed the Powerchip software but kept the Evo pullies.
BTW I saw you at Bimmerfest. Makes me want to get a Bimmer again.

 

I've paid for so many Dyno's that I've lost count of how much I've spent. But here is my last dyno with the HPS SC on. I actually put 5 gallons of 104 Octane and removed all the airboxes and covers and these results are far short of the 387whp that MT pulled on 03/31/05.

I had two other independent dyno's (Superior Automotive on 03/16/06 - 351whp, R&D Dyno on 04/14/06 - 348whp) and as you can see both of these are also far short of MT's number and much closer to the 361whp that I got last Saturday at HoP. The 10 additional HP was probably due to the having the covers off and running 5 gallons of 104. I'm also running DANGEROUSLY LEAN again!!!

 

sorry for the delay...been busy...just got caught up on all the reading...

also had another dyno last on Feb. car got stronger...
Max Power was 408
Max Torque was 434

also ran it once with nos (back in Jan)
Max Power 430
Max Torque was 446

I personally don't see the need to ever use the nos but it is nice to have and the gauge is pretty cool.

BennyZ

 

What shot was this 430? 75? 100? Looks good Benny!

 

50 shot

 

It's good that Renntech worked out everything for you Benny.

 

Mario,
Did you also see the smoke, hear the shrieking sound and smell the strong odor of something burning during my last dyno run? Remember when I asked what that was and Josh saying that it was something about the brake? Did the dyno damage my Parking Brake? I may need to test it but is this normal?

 

I do remember something about but I didn't hear the whole story. I thought it was MT that accidently wrapped the strap around the brake line causing smoking.
Also I thought you were running more than 7.5psi because you noticed you had the smaller 2.75 pulley instead of the 2.85 pulley? "The swap" I was guessing you were running closer to 9psi.
When are you going to put the Kleemann on? Have made an appt?

 

This whole ordeal could of been prevented had Richard did a search in this form with HPS superchargers...

Some of us here have been here long enough to remember Tim and his CLK55....

 

I sent you a PM.
I read about Tim before I bought my Gen 1 but that was the only bad thread on HPS at the time. Now that the Gen 2 has come out, the bad threads won't stop. The Gen 1 is a very simple kit that works well and is a similar set up to a Vortec off the side bolt on kit. Many people did care for the Gen 1 because it didn't make as much power as Kleemann or others. Robert (not Richard) was one of first for the new improved Gen 2 kits, so he really had nothing to go on.
I'm happy with my kit for what it is and I'm not trying to make it compete with Kleemann but where else was I going to get 90hp for 4k. If I wanted
150hp then I would of needed to spend 14k.

 

Thanks, my mistake, Robert, not Richard, sorry.. it was 4am when I was done reading... could barely kept my eyes open...

I was very interested in the gen 1 when it first came out as well, looked too good to be true, great price with decent power!

But after the whole Tim deal, I was uneasy... but we will see... It seems they "sorta" fixed Roberts car... and if the gen 1 is as an easy install as you say it is, I might reconsider, but I guess I will need to get it tune by hop...

 

Why don't we meet up and you can take a ride in my car. We only live 70 miles from each other. Let me know
Mario

 

I think you can't go wrong with the Gen I. Kleeman's low boost kit still costs $9K (without intercooler) and I feel that the Gen I at half the price is a no-brainer and it has been proven to work because it takes advantage of the stock Mb intake manifold which has a very efficient flow.

IMO, the key reason why the Gen II makes little power is because of the convoluted shape and the small openings of the replacement Intake Manifold. The chromed finish and the 8 machined "wings" of the Plenum may look nice but I doubt that it works very efficiently. How else does 7.5-8psi of boost as measured publically at HoP and MT AND a reprogrammed ECU only generate a maximum of 370whp yielding only a 70-75whp gain while the Gen I yielded at least 90whp gain?

It looks like Mario and I are the only folks brave enough to post our dyno's for everyone to see on multiple occasions whether the results are good or bad. In Mario's case - Good and in my case - Bad.

I just wish I had 1 more dyno besides AMGDragon's C55 to convince me to just GO for the Kleemann without waiting for any settlement from HPS. If I see another C55 making over 425whp with either a Kleeman or Renntech then HPS cannot continue to claim that NONE of the other brands of SC's make the advertised power without increasing boost to 8-10 psi.

 

I don't think coming up with another dyno C55 is hard to do... I am sure Evosport has done a few C55's. They prob have all those dynos saved in their computer. But from reading your posts, you prob would want to be there and make sure it was the real deal. Or not, I feel that you just about had it, and I think it is a smart move for your. Being a SC Alum as well, I can't believe that you will be taken for a longer ride than you already have. You are a much better man than I am... I would of called it quits months ago...

Well, I will give Mario a call tomorrow to see when he can meet up, can't wait to ride in his car. And best wishes to your on going battle!

I got your back! Trojans stay together! ( as long as you are not changing your mind about HPS again )
