Havoc,

I'm not trying to be a buzz kill and I also have the mod bug big time. Just becareful and make sure that the details and specifications are shared with you. If it sounds too good to be true...well, you know.

Ask for the specs on the engine build. What's going to be done to beef up the fuel system? Will all of this require a standalone?

For AMGSC: Ask why twin charging? What's the benefit? How will the tuner deal with the parasitic loss of the supercharger? Will there be some type of bypass valve once the turbos spool? What about the additional heat? Beyond 700 HP the 55 cars run out of fuel. How will that be handled?

I'm skeptical because there is no advantage to twin charging this engine.

Just don't want to see you guys dissapointed or burned. I sincerely wish you good luck and I must admit that it's always fun trying something new.

Havoc

I understand what you are saying and I appreciate your input.

I didn't change my block, crank, or rods. I was speaking about AMGSC because his engine is not a stock Kompressor, and he needs to upgrade these parts.

I'm installing steel sleeves that are bored 0.2L into my stock block, my stock crank will be knife-edged and lighten, my stock rods will have ARP rod bolts, but I will change my pistons to a higher quality, stronger and better oiled forged pistons. My oil pump will also be ported and enhanced.

I'm not one that must see numbers first in order to buy mods and I may never take my car to the track. Victor knows what he is building and I know what I'm getting. It's a no-brainer in my book.

VRP is just starting out and the reason you don’t see any numbers is because these mods have just started. He is tailoring to the customer’s needs and what we want.
I hear what you’re saying, but as far as VRP is concerned, I have no worries!

G55K

Good luck with the project Havoc. It sounds like fun!

AMGSC

Is that E55K motor still available? I might want to twin-charge that motor instead of my NA one.

I can also find a happy home for this rare Kleemann Autorotor Twin-Screw with custom pulley that can push boost past 14lbs that I picked up last week!

............Are you totally stuck on a C55 chasis? If not, get yourself an SL65 and be done with it. You can get used one for $80K, minus the money you sell your C55 for, that will bring your cost down to about $60K. I have done the stuff you are trying to do except the turbo. I have rebult my block in my W210 e55, sleeved the cylinders and added low compression pistons and reduced compression ratio from 10.5:1 to 8.5:1. What I'm trying to say is that by the time you are done with what you are trying do do, you would have spent way more than $60K. Yes, I mean it. Don't listen to anyone that tells you won't. Sit down and get written estimates first. Otherwise you'll be in the middle of the oroject and cost will keep rising but you can't quit because you are already half way. Sit down and get in writting, the cost for a sleeving, low compression pistons, s/c, tunning, two turbos, installation, dyno, testing, tunini, hourly labor rate at $80 and hour..........the Sl65 will look cheap by comparison. Better yet, you can get a used CL65 for $55K and sell your C55 and your total cost for the CL65 will be less than $30K. I just think you are about to enter a money pit with what you are proposing.

..........Further, although Vadim knows a lot about cars, I think the idea of installing a Kleemanns s/c in a car with 11.5:1 compression and then adding turbos is not wise. I think Vrus first thought this up for a W211 E55 and in that case it made more sense, but not for your car. Are you dead set on a C55 chasis?

Ted

G55K

Ted is exactly right.

You're about to begin a project that will become a money pit and have the inevitable "one off" quirks. A CL65 with Kleemann or Renntech ECU mods will not only be faster than a twin charged C55 but it will be much less expensive.

I tend to get very nervous when I hear about a new company creating a half a dozen one off projects. I'm concerned that we'll still be reading about these same "projects" 6 months to a year from now.

AMGSC

Thanks Ted. I will get the quote/estimate tomorrow from Vadim and if it's guaranteed within 10% and not over $20K then I would consider it. Otherwise I am planning on just fixing the 1 cylinder, put the Kleemann SC on it and then sell it at the end of this year. The SL65 with an SLR kit does look sweet.

G55K

AMGSC,

Is your Kleemann SC one of the older autorotor kits? If so, you're a lucky man. That was a great product.

AMGSC

Thanks for the vote of confidence. I searched all over for it. It was hard to find and this one had less than 5,000 miles on it. It includes the Airboxes, pumps, heat exchangers, etc.. This AutoRotor had the 4male x6female rotors vs. the 3x5 Lysholm/IHI blowers.

I am considering selling this kit along with everything else on my car when I'm ready to step up to the SL65.

ProjectC55

You have taken the words right outta my mouth! 4 turbo's ridiculous,expensive and not necessary. Why 4 turbo's? And why a S/C and two turbo's? What's the point?

Is'nt it amazing how a car like the Supra,with smaller displ, and one huge turbo have been known to make 1000whp and run 7's at over 180mph in the 1/4 mile!!


You guys must like to spend $$ on thingy's!
2 turbs will keep things reliable ,less complicated and easy to tune! You gotta lot of displacement in 5.5 and 5.7 L's. Try 335 and 350 cubic inches fellas.

ProjectC55

Dude sell the S/C kit separate. Sell the C55. Call it a day and buy the SL65 and mod it! Bam!!
Upgrade the intercoolers ,turbochargers,get a good tune and your all set,done, finished,you have a beast as well.

AMGSC

I got a detailed quote: 12K for engine rebuild with forged pistons and ported heads yielding a 9:1 CR and 450+rwhp. Time frame is 30 days. For another 10K (with R&D discount), a single turbo that will yield 650rwhp+ and another 30 days in the shop.

Which is the better deal? or should I just pass. I only have $20K maxxx I can spend on either trading up or modding up or else I will be paying more than that in divorce settlements. At this point, I don't think I can get enough for my car and mods + 20K to step up to even a CL65. My only consideration are the 600 Bi-Turbo models. So either I wait and drive my car as-is for another 6months to 1 year or I try to negotiate a TWIN-turbo SC or QUAD-turbo for $20K all in, 60 days commitment to finish and a warranty for engine replacement. Some Auto magazine is interested in doing a story on this also.

Any advice would be greatly appreciated. I need to make a decision in a day or two max.

btw... I have a set of C55 stock wheels for sale at $1000 even. Flawless 18"s with Pirelli PZeros (Rears need to be replaced). Can ship without tires.

Also have a set of Brabus Monoblock S wheels for $150 each. Flawless 19"s

c32used

I say just spend the 12k for the engine work and be done with it...I trust more that then the massive rwhp you will get from a single turbo...and imo way to much for the single turbo work...

Havoc

I agree with c32used. Do the engine rebuild now and drive it for a while and enjoy it. You can always add more power later if you like. If not, just wait and drive your car as-is for another 6months to 1 year. No rush AMGSC, these mods are not going anywhere and neither will your wife. Heck, no telling what will be out in a year.

TemjinX2

i think you would be better off just trading in your car and getting a e55 or just selling your car and buy a used car thats already turboed or super charged. That way you just need to upgrade the turbo or supercharger.

i think spending $12k just to get extra 150hp is expensive. If this going to be your daily driver? I dont think 650whp would be a very streetable car. I think 450whp would be better for a daily driver.



I guess if your doing it for the fame, go with the $12k option.

c32used

That is one hot pic of your car Havoc....

Havoc

Thanks c32used! Your car looks ready to smoke the next competitor. Nice color too!

AMGSC

Actually it's another 10K for ADDING a single turbo to blow into the Kleemann SC. Still it's an unknown that I don't think has been done before.

I got the OK on the whole deal with Turbo and SC with rebuilt engine for $20K. Shall I pull the trigger for that price?

What I'm afraid of is the engine throws a rod and puts a hole in my block while I'm driving if I don't do anything. Is 30lbs/200lbs CR loss a sure sign of engine failure in the immediate future?

c32used

Why venture into an unknown with that much power? 450RWHP is no joke and will contend with alot of todays high perfosmance cars....its way more streetable then 650 RWHP so just do the 12k work alone cause you will never see the cars value shoot up cause of the work done...sure people here will see its worth but even here they won't offer much more then what the world thinks its worth. Make the car driveable and trusted and stick to less is more theory in your case.....try to sell your car for more now and it will give you an idea of why stick to less....like I said 450 RWHP is no joke!

spr

I think you need to get in contact with a friend of mine who has it c55 tt'd and is pushing 700 on pump and 800 on race gas . Then you can sell me that SC!!

Honestly though, I would lower the compression and go TT as he as proven it's easier and worked out very well. Doing both seems rather silly. Plus tt has no parasitic drag and when properly boosted with the right units there is not much lag at all. You'd just really want different cams and make it more of a mid and top end monster and then don't go overboard with the turbos so they have good mid boost and will do fine with the top end-

CynCarvin32

The last car I heard about with low compression along those lines had a cracked piston from a bad ECU Tune. I would consider the motor is not doing so well these days. Either just go back oem and trade it in (part it all out) or just re-build it all. Remember your block is not a 55k block so you will need to source basically E55k parts to get the strength needed to run all this boost.

I say just get the CL65 at auction and enjoy that. This C55 will never run correctly. Its just to out there in design!

Good luck

Tump43

I agree with C32used, get your engine rebuilt (spec'd & strengthened) and call it a day. That way you will have a trully durable really fast, absolutely streetable C55 that you can enjoy until you get your next car. With all the mod's you've done and undone, it seems unlikely you could trade or sell your car for much until the engine is 100%. I'm at 409 hp now and want a new car (I do not think I can justify putting more $ into my car) and can't afford a new Benz (Dealer offered me a CLK63 convertible with the 030 package w/5k miles for $80 to $85k) at the moment, so I signed up for the AMG challenge and will take driving lessons -- should be more useful for me than a faster car.
Great saga and good luck whatever you choose to do!!!

AMGSC

I agree that a CL65 would not bring any headaches but I'm not so sure about it being faster. A stock C65 runs the 1/4 mile in 4.2 seconds while a Kleemann C55 runs a 3.8s@431rwhp (see DragonAMG's timeslip/dyno) without my additional mods (LSD, Cams,Crank and SC pullies, Coolmist, Pump, plugs and wires,etc..). The CL65 is an extremely heavy but very luxurious car.

AMGSC

Can you ask your friend to PM or email me? I am interested in his experience and feedback. If the TT solution has been proven safe and makes 800hp, the SC is yours.

have you thought about a 6-spd manual swap?
