better intercooler

[hvmercy]

Yujin, open up a different thread about your question. This is getting way out of topic.

Apologies to the OP.

Whats the good and bad from the Badboy 55? I am seriously considering getting one next summer If my funds can take it. I know my dad will flip shit if I buy a second benz (unofficially my 3rd one).

Idk, Im a modder. I love screwing with my car. As 'perfect' as the E55 may be, you can bet that I will find someway to improve it, whether its looks or performance, I will find a way. Theres not really a big market I suppose? for people who mess with their E-class's. Unlike the W202, the W210 seems to retain its classyness (besides the rims and lights) nothing else is really changed.

[zmatt]

I'm the OP, we can keep it going here if you guys want. I'm having the bumper measure for the intercooler next week so we have some time until I make a major update.


I'm with Yujin. I love to improve things. The M113 is a great motor, it has forged internals stock. But in classic Mercedes fashion they have way under rated it for a long life. And It's definitely worked, of all the people complaining about tings in these cars breaking, one you never hear about is the motor. It's always the electronics. From where i am sitting 5-6 grand to do a V8 swap isn't expensive at all. Now I'm not rolling in cash, I'm a college senior and soon to be small business owner, but people put that kind of money into cars all the time and compared to the price of a new sports coupe or sports sedan it's very reasonable. The E55 does 0-60 in 5 seconds for the NA model. Just think what that motor would make the W202 do.

To put my madness in perspective. I was picking the benz up from my fabricator yesterday for the new intake I had him make. Another guy was there who had a 470 ish hp saturn sky. As far as we can tell its the most powerful sky anywhere. He has had a lot of custom stuff done obviously, he went beyond what the off the shelf stuff could do over a year ago. They were working on some new boost fittings to clean up the engine bay and to improve reliability. I was talking to them while this was going on and my fabricator says that I should just stop where I am and toss on some nice wheels, tint it and go VIP or something. It's a benz why are you talking about tuning when nobody does it? I say that's the whole point. Our community is mostly made up of middle aged guys who buy an AMG and dont know shit about their car and they never track them. When i went to autox you'd be surprised the props I got for bringing a benz. Nobody had done it up to this point. he said I should get a 240sx or something and put money in to it, or if I wanted to stay euro get a BMW. I don't think he gets it.

[Yujin]

Yeah, see, I hate when people say "Just get XXX instead of hooking up your car" wheres the fun in that? Lol. Im not looking to get 20000HP with 2000TQ, I just want to have fun with my car and enjoy doing little things to it. Just like Pagz, he turbo'd a C230, he could have easily gotten an AMG or even some import and spent money on that, but turbo'ing a C230 is somewhat of a rare sight (although costly). Another example is Slammed, he has all those cars, but he turbo'd his C230. Its all in pleasure and a hobby I suppose.

I cant wait to take my car to the track, hopefully next year.

[Yujin]

Update zmatt?

Yeah, Im that guy that just bumped this topic up.

[zmatt]

Well they have extended our AutoX season by two events because a lot were canceled so we had one this last sunday and another will happen in the next few weeks. I wont be able to do it before then but if i can find the time I will get the bumper off and take measurements. it's mid terms time so I've been studying. I will keep you posted. Anyone have a link to steps to remove the bumper?

[gakz]

Just did a 140mile road rally, keeping it at high RPMs and going through some twisty roads. Thing barely got warmer than 85 celsius, glad I got my intercooler.. many times it'd get up to 90 celsius before I got it. It may not give tons of performance boost doing it, BUT I know for sure it has helped keep engine temps down

[Pagz]

Front bumper removal is pretty straight forward,theres two nuts either side of your AC fans - access by removing plastic grill,two nuts either side of the IC - access through front bumper ducts,what i cant remember is if you need to remove the plastic liners infront of the wheels before sliding the bumper off - pretty sure you dont need to,so simply reach in the outer side of the liner from the wheel well and push the clip that will allow the bumper to slide forwards, that sliding braket is adjustable which allows for correction if you need it later.

[zmatt]

Thanks Pagz. Sounds pretty easy.

@Gakz, I'm also having a new pipe made from the IC to the TB at the same time that will incorporate the MAF relocation. I think I'll slap it on the end of the metal pipe on the TB. The IC wont really help with stock boost, but it will help with heat soak so you keep the power and it will help with when I get more boost.

[gakz]

Here is the intake I have, I believe its 2.5" aluminum from siliconeintakes.com; Super cheap, custom cut it all myself and had it welded up... the "MAF" side is 2 pieces with rubber coupler near the pulley (on the SLK its a real weird curve). The actual pre-supercharger intake side will be getting changed up after a while, but you can also see what I have there

[zmatt]

That's basicalyl what I am gonna do. Moving it there removes the check engine light from the new air intake right?

[zmatt]

So I'm looking at my bank account today and I have about $600 of money to play with at the moment. That's about enough for one good mod. Either intercooler/maf relocation or shocks and springs, or maybe new wheels. what do you guys think?

[gakz]

i never had a check engine light from my intake...

[zmatt]

You already have the maf relocation, that keeps it from happening. apparently if you mod the intake without moving the maf it can read over the 5v max the maf can send and it sets a check engine light and the car runs rich trying to compensate for a perceived lean condition that isn't true. The symptoms I get make sense with this diagnosis. When I really put the hammer down and I get full boost I sometimes get it and the result is poor mpg and the smell of gas as long as the code is present. It happened the moment I changed the intake.

[gakz]

oh thats the check engine light you are talking about, Yes.. I had that and put on a 4.7V zener diode... probably affects my top-end pretty bad :/

[gakz]

Its better to actually get a professional volt limiter set-up and limit it right at 5V... I couldn't even tell you how bad it affects my car ive had it on for so long

[zmatt]

well I've read form different sources that moving the maf further down stream helps as the later M111 motors had it in a bad spot. It seems all the slk guys do it with good results. If it doesn't work then I'll look into other options. and yeah, it's annoying as hell.

[zmatt]

So I got the bumper off today and we decided that even though an intercooler can be made to fit with some work, at the boost I'm at i would see pressure drops and it would be annoying to make it fit. Instead I'm going to look into fitting an AEM water injection kit. I'll keep you guys posted as I go. We decided the current plan was as long as it is my DD I should get the injection, pulley, tune etc so i don't have to worry about tuning issues or having the motor in pieces. when I get a new DD we will probably go turbo.

[gakz]

I found the proper MAF clamp to use, its the 5V split second volt limiter. Then just use the wiring guide/diagram I and subby have on benzworld R170 section

[zmatt]

Could you link me to the part and the guide please? I have decent electrical knowledge I should be able to install it without too much trouble.

[gakz]

Part is here http://www.splitsec.com/products/vc2-5/VC2-5.htm

Thread with info on the wiring setup is http://www.benzworld.org/forums/r170...ht=zener+diode



the thread is more about putting on a zener diode and not the splitsec clamp though... but if you use the splitsec guide on how its supposed to be installed with the wiring setup in that thread, you'll be fine.


you'll also notice there is a variation between engines, 98-00 (m62 supercharger) and the 00-04 (m45 supercharger). My reference post is for the m62 s/c.

[zmatt]

Thanks alot.

[gakz]

mine is on the way so i can tell you how it works by the end of the week

[zmatt]

sweet. Who do you recommend i order from? Am I right in thinking this means i don't need to move the MAF?

[gakz]

you still should move the MAF to the position mine is if you have the 98-00 engine with the M62. This 5V limiter just keeps it from limping the supercharger when it goes over 5v.

[zmatt]

ok, so whats the point of the maf relocation then?
