Oh so true!!!! I'm DONE with any more modding. My next car will be not be modded anything beyond a simple tune.

It's been gone far too long during it's lifespan.

"My next car will be not be modded anything beyond a simple tune."

I totally AGREE with this statement....... after my long journey... I'm thinking my next ride will be 997-turbo stock low miles....... no fuss, no drama, no mods

Enjoy your newely born monster machine!

I don't want to sound negative by saying no more mods. Yes I had a terrible experience UNTIL DYNOCOMP took over.

If I had gone to DynoComp from the beginning, I think the car would have gone from stock to 475rwhp and run perfectly in probably less than 60 days. No trial and error, mistakes, lack of shop resources, short cuts, fixing other shop's work, etc.....

I still think that stock C55 owners can have a positive modding experience by having a top notch tuner like DynoComp working on it.

As for costs...Many used performance parts (i.e. my Kleemann headers, exhaust) can be purchased for less than 50% of retail and tunes are now between $500 and $1,000.

After watching the mistakes made by others like myself, I hope you stock C55 owners do not lose hope and get discouraged from performance modding.

I had fun doing this project despite all the pain and heartaches. There is just something to building your own car step by step rather than just buying a performance car off the shelf.

I can only speak for myself, but I don't take your comments as negative at all. It may not be much consolation but I'm sure that our relatively small C55 community appreciates the trailblazers such as yourself that have expended a great deal of time, money and patience defining the upper limits of the N/A M113 envelope. Much respect!!!

The 55K engine is a definite option. When I did my engine swap, I only had a therory of how to recode the ECU. Since I wasn't sure it would work, I used a almost zero mile motor from a CL500. the conversion worked and I have two years and 20K miles of trouble free driving. After I did my conversion Rudy Compart who now works at Speeddriven built three 55K Crossfires. I think bone stock or just a little tuning they are putting out 435 at the wheels which is crazy in the little Crossfire.

You are 100% correct IMO.

I only tuned my c55 to only 440hp but never had any problems whatsoever.

This week-end, I also talked to a guy that has 600hp on his C55 tuned by Vath and he drives hard everyday, drove 50 000 km and never experience any issues. I strongly believe that you need to find a tuner that's experienced and it avoids all problems although it costs more

There was another C55 being tuned at Vath with 620hp! What they do is an entire E55K transplant (Plus gear box and rear axle!) since the engine block is built for the kompressor.. Can't wait to install too

Did you ever take this thing to the track?

AMGSC

I was never able to mount the rims drag wheels that would clear my brembos.

I plan to do it in January. In the meantime, I'm also looking into twin-turbos for an 2006 M3 I picked up this week.

HPF stage 4 FTW!!

This was a great and interesting read. I have a ton of respect for anyone trying something new. Here are just a few thoughts which might be of benefit. I am starting a turbo build for my V8 Crossfire with the help of Corky Bell (BEGi), Bell Engineering Group. He is currently offering a turbo kit for the Crossfire and with a few small changes such as a different turbo and larger intercooler he will have a kit for my V8 Crossfire. Btw, Corky is also very good firends with Brandon at Kleemann. I will be using a 55K ECU to manage the engine with final tuning from Eurocharged. One of the big advantages is no MAF to worry about. A fellow Crossfire owner proved this will work with a Rotrex supercharger on a n/a 3.2 V6 Crossfire. The only catch to using a 55K ECU is getting one compatible with the Euro 2002 SL55 which did not use a bypass valve. I am still trying figure out the part number for the 2002 SL55.

As far a getting more boost out of the Kleemann s/c, you may want to consider twin charging. another crazy Crossfire owner has added a rear mount turbo to the 32K engine in his SRT. With twin charging you will be able to take full advantage of the 9:1 compression with about any boost level you want.

AMGSC

I think my M3 will be much easier to mod although the instant torque of my C55 can never be matched by my soon to be modded M3.

dre5373

+1! Aftermarket support is everything! Compare 43,779 (26,202 coupes+17,577 convertibles) E46 M3s to 4447 W203 AMGs...keep us updated, can't wait to see what you do! Got any pics?

betrezra

Any track updates yet?

Newzchspy

Its been done on the C55, Rudy is doing one for a SC'd C55 as we speak to get rid of the dreaded MAF.

Any track updates yet?

Bump for track updates as well!!!

I ran at Fontana on Nov 9th on stock 19" wheels and got ZERO traction. In fact most of my runs were aborted. My first run while easing off the line was a 12.1@119. On my last run the belt disintegrated and I had the car towed all the way back to LA.

I had the belt replaced at my local dealer but I had to replace the plastic coupler in the nose shaft of the supercharger since the it made a rattling sound after the belt was replaced.

On the dyno, the boost gauage read 12psi so I believe this is now truly the highest boost SC'd C55 around although I don't know about any TT'd C55s.

I plan on going back to the strip this month but must find a set of 15"drag wheels that clears my Brembos in the rear.

Meanwhile, I'm still trying to negotiate a fair price on the Horsepower Freak Stage 5 for my M3. Retail price is over $50K!!!

blackbenzz

You made 12psi with ported heads? Not bad. Get some 16s, doesn't have to be 15

AMGSC

I think the loose coupler inside the nose shaft caused some loss in boost as the pulley was extremely loose and I could actually turn it(without the belt) about an inch left or right before it moved the rotors inside.

I'm hoping that after I measure the boost on the dyno this time, the boost will be close to 14psi or close to 1 bar.

The car runs so smooth that I am amazed at how great a job DynoComp/Evotech they did to tune the stock ECU to accommodate such an extreme change in pully sizes and with bigger injectors and still keep the Kleemann fuel kit installed with the boost a pump activated and the stock MAF too.

betrezra

Awesome news.
I'm making 8psi with my eaton on top of p/p heads, and I'm pegging the mass air meter... so tune is down the road for me too.

betrezra

Side-post - if any of you kleemann guys have a stock kleemann s/c pulley you can sell hit me up.... I need a stock 2.8" pulley for my klee eaton for some tuning/testing.

PTE

Guess what I Have , And you are most welcomed to it. 2.8" steel pulley , I also can get other sizes in Alum , but they are press fit , were the steel is slip fit , For Eaton m-112 gen 4 Blowers.
Cheers _PTEngineering

AMGSC

Pat,
Can you make a 60mm pulley for the twin screw for me? I'd be glad to pay for it, I have an extreme belt wrap so a 60mm won't be a problem with belt slip.
Of course I made need some tweakin with the tune again but it's worth a try.

I don't want my soon to be modded M3 to kick my C55's *** that easily because I'm going with HorsepowerFreak Stage 2 with stock internals for now and it's going to be a close race of 110 octane maps.

betrezra

PTE is THE man! Thx for all the help.

Keep this thread rocking...... can't wait to hear some numbers on this beast!

blackbenzz

So you shredded a belt and instead of remedying that issue you decide to exacerbate it by going to an even smaller pulley?

PTE

If I remember Right you have an Auto-Rotor unit , The Driven pulley for that one is very different Than The newer M-112 Eaton ,That replaced the Auto - Rotor back in 2008. The smallest Eaton pulley I can Get is 63 MM. Keep Tweeking Robert !! Cheers _PTEngineering

AMGSC

The belt shredded due to several possibilites.

1) I put ice cubes on the supercharger manifold. (Almost got kicked off the strip for that). The water could have caused the belt to slip off.

2) The plastic coupler broke inside the nose shaft of the SC and caused the belt to slip off.

I'm convinced the latter reason caused the belt to slip off or disapper since I could not find any trace of it in my under the hood.

Pat,
I found a local auto parts store that has a machine shop and they made me a duplicate of my 65mm in a 60mm so I'm set. Thanks anyway.
