Exactly. Just fun to hear that one. Raw brutal power vs. that turbo sound.

Got a few requests to see how it's setup in the rear. Here's the best pic I got:
It's got a flexible, steel supported, silicon intake made for Turbo P-cars. It's heat wrapped at the point it crosses over the also-wrapped exhaust just to be safe. The MAF is back there too. His painted tip didn't fair too well with the heat from my MIG welder lol.



You can see the filter in this pic:

Hersh and I are good friends so once he gets his boost turned up and we have some free time maybe we can get some runs on video. I think he is coming to MIR for my track rental in December

[deyainrdy4ds]

max, ill try to take sum pics of the turbo when im gettn the cats taken care of

and yea i hope i can make it to MIR in december

[deyainrdy4ds]

cats are off....we ran outa welding wire so we couldnt finish putting on the straight pipes...so we're takin it down for the nite and then hopefully its all set tomorrow so we can tune it and dyno

[rjlawlor646]

update on the performance gain?

[deyainrdy4ds]

replaced the cats with straight pipes but still an exhaust restriction somewhere according to max...and still getting a rotten egg smell when pushin the car.....gunna try removing replacing the precats with straight pipes tomorrow.........would anyone be able to tell me which set of cats are more restrictive?

Its usually the primary cats that are the most restrictive.

[DropTop430]

u can delete the second ones and leave the 2 first ones on !!!!

[deyainrdy4ds]

im jus gettin rid of both pairs...hollowing out the precats tomorrow

If you get rid of the primary cats (or hollow it out) then you might end up getting some CEL lights, at least thats what I was told when I brought the issue up a while back. You should check into that before you run into some headaches when trying to pass the SMOG test, just trying to look out for you.

yea i was told i can use sparkplug nonfoulers...hopefully the guy knows how to get around the CEL....my inspection is good until 5/11 as of now so i can worry about that later i guess lol...i usually find my ways...i dont think ive ever actually went to an inspection station :-X ....heading out to get the precats off in a couple minutes...wish me luck lol

Hello i have got 1998 clk 2300 kompresor . And the thing is that i have car acselarating wery bad . and i was diagnosite by mechanics that have to change supercarge bypass valve(throtle or part which goes to kompresor)nothing changed. still cilinders not burning the petrol, because not enouth air comong to engine. or mechanics say that kompresor koming to an and.
coud you help me with this.
you would give a wery big help. thanks

[deyainrdy4ds]

left u guys outa the loop with sum pictures....sum pics of choppin off the main cats and replacing them with straight pipes and then a week or so later gutting out the pre cats.....i have no check engine lights by just using these things called sparkplug nonfoulers that u can pick up at most auto chain stores....just gota drill a hole in em and then screw em into the O2 sensor hole and then screw the O2 sensor into them (gotta drill the hole so the O2 sensor can fit through the end of it)......it sounds mean as hell without any cats and pretty much full straight pipe.....no cats, no resonator, no muffler...just the turbo at the end.......as some may or may not know...the bad news is it still hasnt solved the problem and max said the only thing it can be then is a bad turbo ...so when i get some time... we're gunna swap turbos and go from there...hopefully thatll get me boostin where im supposed to be....


heres some pics of the cat removal, cat guttin and some random pics of the full setup once i got to finally see it actually up on a lift...











The silver thing is the sparkplug nonfouler:

A guy by the name of Corky Bell wrote a book entitled Max Boost. These are a couple of quotes

Clearly, performance of the turbine is in part determined by the temperature of the exhaust gasses. It is reasonable, then, to expend some effort toward getting the exhaust gas from the combustion chamber to the turbine with the least possible temperature loss.

And

Exhaust manifold design is one of the keys to high power output, and the two-turbo layout inherently offers superior manifold design. The heat loss of the cross tube in V-style engines can be considerable. Remember, it is in part this heat that powers the turbine.

By the time it reaches that rear mounted turbo, the exhaust loses a lot of heat. The rear half of your exhaust is wrapped. You might want to look into using header wrap in the front half of the exhaust as well.

The only company I know of that successfully ran a pipe a long way to their turbo was Porsche with the 951. The engine was a cross flow inline four with the turbo mounted on the intake side.

[tastoto]

Yeah thats right the turbo is a bit far back

[falls profet]

One more thing to add...get that piping all one piece!

You're losing so much heat and pressure from using those couplers and piecing that exhaust piping together.

Hello guys,
since there has been few w208 owner that have went the turbo route on the clk, maybe you guys can direct me on my thought of getting a single turbo installed.

I have w209 03 CLK500 and highly considering going the turbo route (t3 and only running no more the 6-8 psi). My question is what would I need to upgrade on my CLK500 for my 500 to handle the turbo? And what would I actually need?

Thank you guys

Get a wet nitrous system a turbo on a merc i dont know

[riarm]

Wet nitrous system???

Nitrous with gasoline. Gas is injected with additional injectors.

The rear mounted turbo set up is not a new thing that Max has made up and Porsche is not the only company that has had success with this type of set up.

Here is one video example of an install with success with dyno numbers as well. There are many examples of this type of set up by STS if you check out the videos that come up with this one after viewing it.
