Glad you tracked down the problem.

If you want to see what more fuel and a bigger turbo can do a 617 (or atleast a bit more fuel) go check out the 617 Full Load Adjustment Procedure thread I started.

Some good info from some great people over there. Really making leaps and bounds figuring out this bosch IP.

I've been keeping an eye on that too. The 617 seems like it has some pretty stout potential also.

Recently I have removed my mass air flow sensor completely and just have a three stage itg foam air filter in the rubber tubing just on the other side of the heat shield. I also have been running regular diesel for the last three tank fulls after noticing my 0-60 times were consistently .75secs slower on biodiesel. With the extra power from the full load adjustment my tranny modulator on the injection pump needed adjustment. I was able to adjust it so that I did not need the boost pressure in the circuit for shifting firmness at wide open throttle. It shifts soft when needed and firm when needed. Lately because of the mass air removal and also lack of pressure tube plumbing ( I have it direct from manifold to alda) the car feels more responsive and powerful. So after reading the last couple of pages of posts I was inspired to do another g-tech pro run. My first attempt felt great with a perfect power brake and super off the line jump. It was feeling like a promising run. Well, I clicked off a best yet 7.40sec 0-60 time. I was not able to stay into it for the 1/4 mile time but I was stoked. I did not look at the egts but they have been staying below 1200F only get a bit above if I stay into it past 100mph.

So that is with stock pump and turbo, small intercooler, full load adjusted 1.5 turns, cat hollowed out and muffler, mass air and direct pressure to alda connection. Man these cars have potential!! Yee Hah!!!

For comparison. A '92 - '93 400E has a 0-60 mph time of 7.1 seconds(2.27 differential vs 2.65, yet). You're getting up there. That's splendid news.

I'ts good to remember that soft springs affect a lot to G-Tech.

I find it hard to believe that you can actually drive uncer 8 seconds 0-60 mph with stock setup. Stock pump hardly can give you more than 180 hp, and that is the same ammount of power that 300 E can give you. Turbodiesel weights more and has shorter power range (I mean rpm:s) which doesn't help.

Well, I drove my ex-wagon with G-Tech 0-60 mph 4,56 seconds with little traction problems.

From 100-160 km/h 5,1 sec (about 60-160 mph)

At real cold tarmac (+4 celcius) 1/4 mile 13.07 / 117 mph, I could open the full throttle at 70 km/h, not earlier as there was no traction at all in the begining. Measured with G-Tech.

Car was S124 with modified OM606 turbodiesel and automatic tranny. Weight 1680 kg (3733 lbs) + driver + lots of tools, around 1800 kg / 4000 lbs.

Perhaps my new car will be little faster

I also did this, I'll have pics of my way while still retaining OE air intake box soon.

Mauri, did something happen to your 124 wagon? I haven't been over to the mersuforum site, recently. Can you elaborate on that, please?

The end of that sentence made me very happy

I have verified my 0-60 times with a stop watch too and I get virtually the same times. My speedo is pretty much dead on accurate too. I do have a brand new head. Maybe that makes a difference. The direct manifold to alda connection definately has the fuel kicking in earlier. I felt no lag out of the hole waiting for the turbo to spool. It just darted. And it was the first time it every did this. I am running 16psi and I have full boost at 2700rpm.

Mine is like this also, I'm just curious if that being setup that way has any negative effects long term... as mine is the same way.

Does turning down the boost to say, 12-14 make any difference in power/smoke?

Sometimes the boost can be uproportionally high compared to the fuel being injected...

AFAIK - my boost level has never been messed with, I never have and if the former owner is as silly as I believe it hasn't been.

I meant to say that my Switchover Valve was bypassed.

Okay.
I wasn't sure what the stock setting was. As we have discussed before sometimes upping the boost gets you nothing but higher EGT's
But stock should be just dandy safe.

I leave a generous smoke cloud behind me on power braking and quite a smoke screen at night during full throttle on the highway. It seems to me there is room for more air and more power. A larger intercooler/turbo maybe??

Smoke while power braking, to me, means that you need to back off the ALDA setting (leaner). Smoke while at high RPM and WOT means you may need more intercooler capacity and/or more boost...?
