These are not in chronological order but they are some of the stages and steps gregc went thru with tuning his custom supercharged CLK55 with the splitsecond system. TUNING IS THE KEY! JOSH ,GREG,MARIO,VADIM,MYSELF,and I'm sure several others will tell you that!!!! I think if you get the tuning right you'll be happy but do this b4 you euthanize that new 5.5l motor.

 

LOL! the look on the owners face was priceless!Whata dope!


They ran 35lbs boost result 450-480fwhp and 380-400ftlbs of TQ.

I only ran 21lbs of boost on my 6 bolt and got 412 sae awhp/341.71 ftlbs tq 11/11/04 The saying is usually 10-15hp per lb of boost for every psi over stck boost.If I would have run the same amt of boost I would have put down 500 and change to the wheels. This is why I asy TUNING,TUNING,TUNING!!!!!

 

Actually, the gauge only went up to 35. I'm guessing they ran more...

That site has a lot of awesome vids...

 

THIS IS IT! Tomorrow morning at 8am Jesse is going to chip my car and then call me when they are ready to dyno!

All of you have said the same thing correctly. It needed tuning. Now it's going to get tuning with the ECU mod. Combined with the 37lb injectors, extra lb of boost from the smaller pulley and belt and the K&N's I should see at least 430rwp since Fast 55 hit 420rwhp without the pulley kit and ECU.

I hear you about the FMU adjustment but they don't fit in the 2006 C55's so HPS assumed that the newer stock ECU would adapt by itself.

By the end of Friday we will all know if HPS pulls up to Kleeman or not.

Dyno's with my pics will be posted.

 

Sweet!!

The Truth will set you free!

 

Yea, well an assumption can blow your motor! They should have dynoed the car b4 giving it to you to make sure all was good!

 

I can't wait, I wish you all the luck. If you are happy with the results at MechTech are you going to confirm your dyno at HOP later today? Will you be present for the 8am dyno today?
Keep us posted

I just noticed this on their website - this pic's been on there as long as I can remember but I never really paid attention until now. Looks like they never had the fuel tuning right...

So....HPS is going to (CHIP) your car....did YOU read the Warranty from HPS?

Unintended Use: HPS Products are engineered and designed for installation on stock OEM engines. After market engine modifications including but not limited to on board computer enhancements, performance software and power chips can damage the HPS products and/or cause performance and reliability problems with the vehicle. HPS specifically advises against the use of any HPS product on an engine that has been modified in any way from that which was delivered from the factory. The HPS warranty may be voided if problems to the vehicle are attributable to the after market engine or on board computer modifications. Please consult an HPS authorized representative if you have any questions as to the compatibility of your vehicle's engine with any HPS product.

Good LUCK on the Dyno...I Hope the gains are there

 

Mario,

Why don't you tell us your experience with Jesse.

DAMN! 17.1 AFR S/C! That's grenade territry for an F/I car much less a N/A car under full throttle.LeanLeanLean! That car should be running in the low 12's to mid-low 11's AFR.
When I had a bad MAF my car ran that lean and I only posted 260whp on the dyno.The ECU protected the motor I'd say because we were dynoing the hell out of it.Changed the MAF and here came 13's(AFR) and whp went to 293whp. TUNING TUNING TUNING but also pretty much a bad MAF in my case!


Be careful AMGSC! Be careful!

 

Make sure You read this..re Warranty and Emissions From HOP!
From the Hop web site

Can I install a smaller pulley for more boost?
HPS superchargers have been carefully engineered to deliver the best overall performance without sacrificing reliability and durability. Of course, a smaller pulley can be used to spin the supercharger faster for more boost, but this will not necessarily make more power. In many cases, in fact, we have seen more boost result in less power. The key is getting the right combination of components with the right calibration. It has always been in our best interest not to “leave anything on the table” – if there were an easy way to reliably increase the performance of our supercharger systems, we would have done it already. In addition, an HPS-supercharged vehicle equipped with a smaller supercharger pulley would no longer be emissions legal, and void the HPS warranty.

 

If HPS themselves is doing the upgrade at HOP,how would this apply? Or am I lost again?

 

I think Mark meant HPS. HPS stated ECU mods voids the warranty on their kit. Not HOP.

 

No I understand all of that.I'm saying that I thought HPS was going to add upgraded pullies and injectors to AMGSC's car themselves so how would the warranty void apply in that case? To me it obviously would'nt unless I'm missing the part on whose doing the actual wrk and where!

 

Mario,

What was you experience with Jesse?

 

AMGSC: There is an old saying in many cultures:

"You fool me once you are fool, you fool me twice I am a fool."

I wish you best of luck.

 

Vadim, never heard of that saying but i've heard of......

"Fool me once shame on you, fool me twice, shame on me".

 

So what happened with the results? The day is almost over and where's the dyno sheet? I'm guessing they're still tuning it?

 

All i can say is........Jesse did an EXCELLENT job !!! Solved every problems except for one minor problem but he ran out off times. He will continue next week with AMGSC's car. Most of the day he was in the meeting with Mech Tech and HPS going over an agreement and signing an agreement. The only one minor problem is, we're not seeing 7.5 psi with pulley upgrade, it was still showing only 6-6.5 psi on the dyno today. So HPS think something might be wrong with the supercharger. HPS will completely replace it with a brand new SC next week. Stock pulley is around 6-6.5 psi. I also see 6-6.5 psi on mine car too with stock pulley. What really funny is, Josh gauge recorded a 7-7.5 psi with stock pulley !!! How can this be when the stock pulley on the 55 kit only design to run 6-6.5 psi. Obvously, Josh's gauge was wrong !!! The final HP will have to be wait until next.............................
Oh btw, the air fuel ratio was.....11-11.5:1 (straight flat line all the way up to redline).

 

LOL!

 

Just got back half hour ago from Mechtech in Escondido. Adam, Bill, and Jim were all present when I arrived this morning at 10am but Jesse arrive at 11am due to a flat tire on his brand new Porsche (Sweet ride).

Three HPS cars were at the shop today. HPS's very first C55 install (my car), their very first CL55 (linh's car) and their first CLS500 (Eric's car). Both my car and Eric's car were tuned today but Linh's car has to be rescheduled to next week.

Eric's AFR is still a tad above 13/1. My car had a flat 12.5/1 all the way from 1500 to 6800 rpm on 3 consecutive pulls so when it comes to AFR he hit a home run with my car within 15 minutes. My AFR was 15/1 when he started. He also removed the speed limiter and increased the shift rpm from 6500 to 6750. I felt the responsive immediately after I test drove it. The shifting difference is like night and day. Fantastic! However, it took him almost an hour getting Eric's AFR down to about 13.5/1 but we ran out of time (5pm). So I was happy so far.

Now the downside. The smaller pully that HPS installed on my car ACTUALLY dropped the boost on my car!!! I witnessed my car pulling 7-7.5 PSI at HoP last Thursday. I told Bill and Jim this fact and they think that Josh's Boost Gauge is defective, faulty or not calibrated. Linh said Mechtech's gauge was accurate because he had his car dyno'd nearby and the boost was consistent on his car.

Bottom line power increase was OK for now but they are not finished. I gained 55rwhp to 365rwhp from the tuning, larger injectors and possibly K&N filters but lost 1.75 psi of boost because they recorded only 6-6.25 psi today!

How can I lose almost 2lbs of boost witin 48 hours? Anybody have a clue????

The HPS team has practically guaranteed me well over the 414rwhp dyno chart I got the first time. They will investigate where I am losing the boost and correct the problem Monday morning. I asked if the smaller belt was not tight enough but Bill said it was plenty tight. They will check for any new vacuum leaks. Eric's car easily made 7.5 PSI on his CLS500 using the stock HPS pulley.

Worse case scenario. HPS said they will try putting another Supercharger on it to test if my blower itself suddenly developed a problem.

 

PERFECT on the A/F and the fact that HPS is doing all they can to remedy this issue.Too bad You & AMGSC had to be the guinnea pigs though!But better for me!

By the way,we're missing one thing though! What was the RWHP since you did get you're AFR's if they recorded it?

 

365 whp at those boost levels with AFR in the 12's still says something is wrong. So with the tuning you saw an additional 30 whp gain. Is that what I'am understanding?

Linh, where you present to see for yourself that Josh's gauge was defective? Seems like you assume alot. You say that AMGSC's afr was 11 to 11.5.1, and he himself the owner of the car says it was 12.5.1. Already right there, there is a difference from one person to the next. From what I've read so far 90% of this topic is based on assumptions and lies.

Tuning under WOT is one thing and it is not a complicated matter. Tuning for partial throttle and engine loads is another.

 

Even though we are the guinnea pigs we have no choice. What would you do? Nothing? HPS is going to great expense to rectify our problems without charging any of it back to us. I understand the warranty covers the problems but not the power upgrades they gave to me. When they get everything solved I think EVERY past and futue customer will benefit. I think all you guys owe Eric, Linh and I a drink when all is said and done.

Remember HPS only introduced this Gen II kit a year ago. Give them some slack and if they made some errors in judgement in the past they are doing everything they can to redeem themselves now. Remember we are all human and I can forgive as long everything goes smoothly from here on out.
