"Adam did say the ECU would re-learn itself to the new hardware but I later found the added FMU was the culprit." LOL..........Adam alway have an answer for EVERYTHING but in reality, he does not know jack about car, not even his own sc !! Even Jesse said so.

Considered yourself lucky. I've have try everything to make piece with HPS but Adam refused to work it out with me. I even offer him to sell my sc kit like he did with your sc but he still refused to do so.

Getting my money back is not even importance to me anymore. Getting HPS back where it count the most is what we will do. I'm just about done writting my whole experienced with HPS sc. My post will be very detailing about the whole experienced and shocking at time.

Took two hour whole hours and finish reading the whole thread...

.... hum. ... any updates yet?

.....

I think its my time to put it on the dyno and see how my Sc running at 6 psi would do...

E55Cent

Rich, is your car done? did you get your 90mm intake? We should have 6vettes, Viper, E55, and what ever else. I know some guys with Lambo's that might come along.

Richard Galing

Not yet, LPE sent the Fast 90 but just notified me not to install it cuz they received a batch of units with improper sealing. And, the car will be at the body shop soon for a hood change.

Have you checked out the exotic rides at Euro-Sunday in Calabasas, we all should meet up there sometime soon.

I was at Channel Island yesterday...cool place.

Just ordered this Pump: Bosch 0 580 254 044

Bosch Rating: 200 LPH at 72.5 PSI and 13.5 V

Bosch Approximate Crank HP rating at 72.5 PSI and 13.5 V: 750 HP


see if i can get away with it without the BAP and get the correct 11.7 AF

Richard Galing

If you don't mind me asking, which supercharger unit are you using?

Good choice on the motorsport 044, I've used it before...but mounting the darn thing won't be simple. My E430 and your CLK55 uses the same Bosch 69529 FP, the 044 is larger in thickness and wont fit your OEM bracket, you might have to use a quick release mounting bracket (I'm not sure about the clearance area on the CLK55, but the E430 is tight as he!!) and if I recall correctly it's got a 18mm dia. hole and 1.5 thread/mm pitch...it's been so long I can't remember the stock dia., well anyways you can get AN adapter fittings.

Don't rule out the KB BAP, it's a simpler install. What's your fuel pressure reading @WOT?

Good luck!

Procharger C2 ...

... ... about the same as the HPS Gen I, but with custom A A intercooler..

Yeah,. I will need to buy the quick release, and the AN adaptor... btw., do you remember what is the size on the mercedes?

Richard Galing

Cool...I had a buddy in NY who used the same head unit on his CLK55 years ago. How's your seals holding up, I've heard oil seepage was a problem on the C2s.

Off the top of my head, I don't recall the inlet size of the OEM...let me dig up some old info and send you a PM when I find it.

Here's a pix of the Q/R bracket & AN fittings on a 044.

mtimmy

exactly !. the C2 leak oil like crazy,. I am so disappointed with ATI's customer service too.. I tried to send the unit back to reseal every thing..

I ask them what the price be,. they said send it back and we will let you know.... what the hell..

Btw: I saw that pic too., from jayracing.. do you know if that guy is good? I am thinking of buying the bracket and AN adaptor from him

Richard Galing

Okay...it's an oil leak and not seepage, whoa...not good! Yeah, ATI's notorious for lousy customer service.

The front or high speed seals is likely shot, I wouldn't let the front seal go for too long...bearings could be next.


Unfortunately, ATI is your best source their seals can withstand RPM required. It's a 7-10 day lead time and cost $320-350.

Becuz of it's compact size, not many uses the C2, I think the 350z ProCharger kit is package with the C2.

You could try Next Level Performance: www.nlperformance.com They use to replace seals in-house, I'm not sure if they still do tho.

Yeah, they sell the bracket for $30 and AN fittings for $10-15.

Good luck!

mtimmy

I wonder if any places do sell those seals seperate....

hum... I have emailed the company you mentioned I see whats their responses is..

thanks for your help

Does anyone know if a rebuild engine require "breaking-in" before the piston rings is fully seated? And how long?

MARK CUMMINS

Yes Vary the speed..But NOT Redline for aprox 1000 Miles..do a oil change
send the oil sample out for testing...

Good to hear the CL is back up...(WITHOUT the HPS)?

Clk&Slk

Thanks Mark, i know about the break in procedure. I'm a little worry that one of the cylinder has a high blow-by that cause randomly misfired due to oil foul the plug. It only got about 500 miles on it so far. I sure hope that ring will eventually wear itself out to a perfect seal. As for the sc, the car is back to stock now.

JR1

Rings seat in a matter of minutes now a days on these cars. Rule of thumb "drive it like you stole it" Really the only wearable item that has break-in are the piston rings. If your getting an oil fouled plug that is an indication of oil contamination within the cylinder. My advice first do a leakdown test of all cylinders, then do a compression test both dry and wet tests.
Fresh built race motors have 4-10% leakdown before they are ran. After 30 minutes of running they usually go down to 1-4% leakdown. If you have anything over 12% on your motor you have a problem, especially it being "fresh".

Clk&Slk

Josh R., thank you for the advices. "Drive it like you stole it", i wish i would find this out from day one. It got only 500 easy miles (never floor it) until when i did a search on google two days ago and the break-in procedure said to do the same thing as you mention and i did noticed very quick improvement. I don't see black spot deposit on my rear bumper anymore. It look like the seal is getting better. I still have radom misfired but i get it due to the old foul plug still in it. I did changed my oil at 500 miles and see alot of tiny particle metal deposit in the oil filter.

I just found out from another HPS customer that his Supercharger crankshaft actually broke off! This is the second incident. His first incident was already reported by me when his car's engine suddenly shut off while he was driving on the freeway due to faulty wiring of the intercooler pump to the computer circuit board.

Please ask Adam to check your intercooler pump wiring AND the crankshaft for any structural defects such as hairline cracks or fractures. Make sure that you did not get the crankshaft that came from the same lot as this unfortunate but patient customer.

E55Cent

Hey Robert when are you taking the HPS blower off?

AMGSC

I'm just curious to see how long this Charger will last before something goes. I can't believe it still hasn't ruptured.

NitrogenBalance

I can't believe you still have it on....

I just registered with the SpeedGallery.com to race my car at ButtonWillow on Wednesday (June 21st). It will be a full day event. I am putting special high temperature brake pads on. Now it's time to see if the HPS kit can stand up to 8 hours of 115+ degree heat at full throttle. I will also post my time slips and video record some of my runs as well as of the other 30+ cars on the track. If anybody from California is interested in participating please send me a PM.

Vadim @ FD

Sir, now I am finally convinced you are into S&M.

In my numerous years of experience of tuning cars, I have no doubt that you will "GRENADE" your engine.

You will join the ranks with other POS, oh sorry, HPS customers like Lihn (clk&slk) with destroyed or damaged engines.

This is the best way to loose $25,000 of your C55's value that I can think of.

Why you keep doing this to yourself will remain a mystery, sort of like "bigfoot" sightings.

I wish you best of luck.




P.S. Mistress HPS is available on Wednesdays. Just ask for Father's Day Special.

AMGSC

What's the point of Supercharging a car if you don't test it on a track? Besides this might give me a good reason to finally remove it if it fails to perform. I've got Kleemann or Renntech on deck anyway. As long as the only thing that blows is the charger and not my engine.

Actually, I'm only guaranteed about 4 hours of actual driving and I'll probably let it cool off every half an hour or so. I've told Adam and Bill that I needed the heavy-duty heat exchanger and intercooler pump and they refused to offer it saying that the test pieces did not lower temperatures at all. Now let's see how the cooling components of this HPS kit holds up because it will be absolutely scorching out there according to the event organizers.

I will actually be racing with other cars on the track doing laps. I'd like to blow a few M3's, RS4's, 997's, Z's, IS350's, and possibly a few stock vettes away since there will some of each this Wednesday.

AMGSC,

I think you will be disappointed. Good luck and may the HPS farce be with you... (pun intended)
