Yeap, I rented an OBDII meter at Autozone and got error code P0171 (System too lean - Bank 1) before I got to Jessie. He took about 15 minutes to dial it in. Now it's running fine with no CELs.

When I got home last night, I checked the SC intercooler tank and it was empty (well about 1/8 inch of coolant at the bottom of 6"x6" tank)!

Now I know why Jessie told me the car was too hot to get the horsepower up. There was no coolant in the intercooler!!

I also need to call Magnusson and get a refill of the Supercharger Oil just to be safe although I have'nt checked it yet.

Who knows! Maybe 425rwhp is still possible!!! (With a smaller pulley, Splitter, Johnson Pump, Secondary Heat Exchanger,100 Octane?). With headers, hi-flow cats, cams and Quaife maybe 450+rwhp???

Hey Robert, I can see you are still at your old tricks. So when are we going to race. I'm ready for you even with 120,000 miles
Call me.

Thanks for the invite but I better check to see if I can make 425rwhp before I even bother plus the fact that I can't get any traction without Quaife.

If you have no water in the intercooler tank then.....where did it go? That should scream 'warning' to you. Do remember the leaky intercooler saga? Coolant and oil wont mix and can cause serious damage to your engine. Just be careful.

I'm hoping that it burned off from numerous dyno runs, hard driving + 21K miles so far in 1 year of ownership. Besides, Jessie checked the oil and there were no signs of coolant mixed with oil based on the lack of a milky color and texture.

Should I start worrying ??

I'm hoping that it burned off from numerous dyno runs,

The fluid is used to cool intercooler core, not to be burned off inside the engine.

If it is missing, you either have an external leak - which means that the fluid leaked out due to bad lines or bad reservior. If it is internal leak - it is going inside the engine, which can possibly result in hydro lock in one or several cylinders, which in turn results in bend rods and destroyed piston rings, since water can not be kompressed.

If there is no intercooling, than the air temperatures go up and engine detonates.....................

Which is bad.

But it seems that you do not care.

Neither now, nor before.

There is a separate intercoolant tank for the HPS kit. The good news is that it still had traces of coolant after 21K miles logged on the kit. The bad news is this coolant should not evaporate as fast as engine coolant according to a knowledgable source. I am going to watch the coolant level like a hawk everyday for the next week. If it starts dipping again I will have it off within an hour.

Sorry to hear this man...Sounds exactly like what happened to Linhs CL55 before it blew-up..

Coolant doesn't burn off, if you can't find see any leaks in external hoses or coolant tank, the next place is the intercooler leaking directly into the engine.

Edit: Just talked with Linh, he told me he was driving the car and Adam was the passenger.

It may be time to pullout the intercooler and look at it. You need to find the leak or this may be the end of your engine.

Why worry? Its just a car thats got one foot in the grave. Might this be foot #2?

Ya we AMG owneres never worry when coolant vanishes. It just happens all the time... it makes the car lighter and faster!!

And this guy wants to make tuner parts? Try ASE Tech school day #1 first.

You dont even need a blower to give this guy a run for his money. Hes back to thinking he will make 500hp on that car! This is fantastic.

1 buck on Mario's car!

The tank was EMPTY again! This means that the entire tank full of coolant disappeared within an hour of drive time (35 miles!!!).

I called Adam and he told me not to post anything until they inspected the vehicle. This morning I was informed by HPS that they are not responsible and that I should make an appointment at Mechtech for the inspection at my own cost!!!! They also claim there is a possibility that Jessie sabotaged the Kit!

Jim assured me that it must be an external leak however, I told him that my car is running really rough now. This morning the tail pipes were spewing so much white smoke that I must conclude that there is water in the engine!!!

This is NOT LOOKING GOOD!
I have an idea! Add more mods, and hit the dyno again. You'll see 500hp before you know it.

Actually sorry to hear this bro, but don't be surprised if the diagnosis is the same as we predicted, this sounds EXACTLY like Linhs 55 all over again.

AMGSC, If I'm not mistaken, and HPS told you Jessie may have sabotaged the kit?? that's slander! NO way Jessie would do that, he has a prosperous business, he wouldn't shoot himself in the foot like that...That's just wrong on so many levels..

You should take your car to to a totally independant shop removed from any party having anything to do w/this kit, they'll give you an un biased opinon/diagnosis of what went wrong. good luck my friend.

Fill the intercooler tank with gas for extra boost!

this is just crazy, I think this motor went Kaboom! I think a new C55 motor is about $15000.

Didn't we tell him numerous times that he should undo the engine mods before the engine blows up? I wonder who's fault is this? Haha.....

Well he is way past the point where he can blame HPC. He knew there was a serious problem a long time ago, but decided to ignore everyone's advice and just keep going. Too many hands have touched the car to be able to point to one dude or company. He will be paying for all of this out of his own pocket.
