I don't believe Josh to have any plans to turbo charge any of the project cars. His core approach tends to involve vortech superchargers.

OK I'm here! Tell Josh to bring it onnnnn!!!!Nothing wrng with a friendly lil competition.That's what this forum needs in my opinion. F/I vs F/I Josh , and hope you can make it out east.Let me know!!!

[Under Pressure]

I hope no one gets shot in Shug Night's car in Vegas over this West/East hp contest. For what its worth, this 5.4L W202's are some bad muthas, and they are already in existence (as in, could be dyno'd today). If one of the 5.4L's supercharges, its pretty much over unless someone swaps in an AMG 6.5L twin turbo!

My friend sent me this ... Gotta love insanely modified race cars that =DON'T= have to run within restrictive rules set by the World Challenge or CanAm, etc.. In an effort to "equalize" the field, the make it so no car like this could ever run.

Jeff (speedybenz), this one's for you:

Somehow I think you did better your 1st time...

CanAm restrictive? Man you are hardcore!

[98c43amg]

...err, woops! ...serious flub-up ... definitely not CanAm. Gran-Am!
I was looking @ some classic cars before that, Chaparral 2J, and I had CanAm on the brain ...

Ain't nothing wrong with that at all! In fact, I'd encourage it!

[J Irwan]

woah...


I didn't this thread going to heated up this way.

I was encouraging a healthy competition... (hint hint : kameray guy ).


Anyway, let keeps the focus on cars discussion..


Damn now I wish I have a C43 so that I can do the engine swap
All this 5.4L conversions make me drool..

Regardz,

Carl ... this has been a few days of extremes. I just went from total exuberance to "eh, it works".
Against my gut feeling though, I the reprogramming of my ECU (I couldn't be there) happen, and guess what .... You got it! It lost all of its luster.
It's no longer a torque monster. There's a delay to movement of the foot pedal. And when it runs, it just doesn't run as hard ... It thinks about applying the torque while the RPM is rising, instead of being 100% on from the split second you punch the trottle. [snip]

Update for any that care ... the car's doing much better today. The car must have been in some weird mode; perhaps having to do with the tranni getting stuck in second soon after I got going.

I'm beginning to think having the AC on has something to do with it, as the AC was off today. (I hardly ever used my AC with the 4.3L motor) You'd think with all that torque a lousy AC wouldn't make much difference... Does everyone else notice the AC sapping the power to a noticable degree?

Very nice C55, what sort of times are you guys getting 0-100kmph?

definitely 5 second-ish ... I've owned the "RoadDyno" for years ... time to install it!

BTW, I'd mentioned Jeff owned his own MB Star Diagnosis Computer ... but he didn't need to use it. The motor swap was 100% plug & play ; old motor out, now motor in, start it up, run it, and smile.

Nice.

By the way, did you ever just consider boring out your previous 4.3L into the 5.4L as a possibly more affordable alternative? If so, what made you choose the swap anyway?

I dunno ... I wouldn't have gotten the trick silica sleeves that's pressed into the block while the aluminum is hot so they fuse with it, and beefy bottom end. Plus according to Josh R the 4.3L motor has its limits to overbore. Click Here and scroll up to Josh R written 04-13-2005 01:57 PM.

Now that whole process would be very expensive.Just about everything in the bottom end would have to be new.

I forgot to mention ... When I heard C55's were made in extremely limited quanitites (50?) and only available in Europe, I wanted one. I would have bought an E55 in 2000 or 2001, but a) didn't have fold-down rear seats b) my wife and I didn't like the dark burl walnut wood used in the dash. So I've wanted to do this since about 1999 or 2000. The first 5.4L motors I found about 4 years ago were out of ML55s used as crash mules down south in crash test certification. However they wanted 15K for the motors. Brand new, but I wasn't up for paying that much then.

You can have my engine when I do a swap.

I meant to do the swap for 5.4L not to 4.3L


if I do 4.3L I wouldn't gain that much


Look like we have another candidate for 5.4L swap from the West land

Doesn't jnenad16 have a E55 motor for sale? Shipping from Hawaii to you in Cali shouldn't be too obnoxious.

:-o i need to know more about that c36t.
what sortof setup is he running on the comp/injection side of things, it the biggest point of contraversy

c280nz,

I talked to 'da man today wit'da c36t. I hope I understood and transposed everything correctly.

He's running an M48 Motec stand alone system for ignition timing and fuel map. He did the programming himself.

He's using a fuel pump out of an S55.

Using 65 lb. injectors. (aren't those frigg'n huge?)

Hope this helps.

I may be going to dyno tomorrow with the chip tuner and Jeff both there. Carl was to be there but -- you ready? -- an employee driving his car out of the car wash nailed the gas instead of the brake and got into a head on collision with it!

that reminds me... I've been thinking about a unique way to run centrifugal superchargers the last year that I'm thinking I might want to patent as I've never seen it done before.

714guy,

I asked Jeff about this today. He gave the exhaust gaskets to a fabricator, and that guy made everything custom ... pipes and flanges. Would you like me to find out the fabricator's contact info?

Oh yep, sorta already presumed he would have gone stand alone with the power hes making, hes stepping it up hard out. i have no intention to go standalone, to complicated and expensive for a pleb like me :-(.
im not sure what 65lb injectors are, we run metric here, but at a guess thats prolly like 850-1000 cc * 6 injectors :-)

whats the basics of your idea for a centrafugal sc? if u dont mind me askn? not intention of copying just read a fair bit of everything that can be done for them and it may have already been tried

For reference ... Doing a search on this board (this board is incredible) I learned that the C43 uses something like 24 - 26 lb. injectors ... so 65 lb. injectors are a mega step-up over that.

Sorry, I can't say. I have to do a patent search and discuss with an attorney specializing in this field. I just don't want to chance it in such an open forum.

Thanks, for the info. Just didn't know how i could get the flanges.
