50harley is it on the motor yet?

 

[50harleyrider]

No,
I'm a little behind on that project as I have an 03 TDI jetta I need to move out first. I do think I'll get the HX35 and the M pump on the w210 and shake them both down before I transplant the engine into the F150. Does anyone have any advice on how best to clean the lifters on the OM606.962? I've heard just take the cams out, remove them and boil them in hot 20w motor oil to remove the sludge and they are as good as new.

 

[Atg]

No sorry I don't know how to clean them,, but hot oil sounds good.

I am going to size up some turbos for a clean 150cc compound setup. Seems like hx52.

The hx40 starts to spool at 3k with these big pumps.

Baldur on the STD forum has a programmable ECU for the E pumps supplied on the om606.962 for $650. I'm gonna buy one from him and try it before I convert to an Om603 Super Pump. His ECU will also be great for VNT turbo(s) The 6mm elements OEM on the E pump will get me well managed 300hp with the HX35 and a good IC (I hope) .

How many cc of fuel do you figure you need for 300hp? And what rpm do you want to make that power at?

 

[Dougal]

I'll get some turbo sizing calcs done when I can find the time. Life has been a bit hectic lately.

Happy to send some beer money your way Dougal if it will facilitate things. You should just set a standard fee I think. Lots of pretty smart people seem unable to get compound setups sized properly out of the box.

Offer appreciated.

I got some time tonight to run the HX35-12cm numbers on the OM606.

It looks like it spools around 4000rpm using 17:1 fuelling (hot but minimal smoke). You're only going to see single figures of boost below 3000rpm and performance below stock.
You can hit 30psi boost by around 4500rpm and I capped this example at that boost. It sits quite nicely on the compressor map too.

Fuelling is around 100cc/1000 shots. Torque hits 600Nm at 4500rpm. Power maybe 280kw (380hp).

Looks like the HE221 (6cm) will run hard up to around 4000rpm with 30psi peak. It hits the wall after 4000rpm.

over 600Nm torque from 2000-4000rpm with low end far better than stock at all points. Also looking at 100cc/1000 shots of fuel.
Peak power around 220kw (300hp) at 4000rpm.


150cc is definitely compound territory. It's about 4x as much work to do a compound set so I'll need a bit more time.

 

[Atg]

Yah that sort of low end is what I'm looking for. I could do that even with the stock manifold.

 

[Atg]

I'm guessing a compound setup would benefit from the 7cm or 8cm exhaust housing on the he221w. I haven't driven this car enough to know whether I would exceed 4000rpm around town or not. On the om617 I run it that hard all the time, but it has a lot less power and torque.

Mercedes made these motors over square, ie bore larger than stroke. It is hard for me to even thing about a motor with 3" of stroke, but that's what the 606 has. Hence not very torquey and they like rpm. I have the rpm limit set at 5500 for now, but I can turn it down from the outside.

Does the turbine housing hit the wall, or the compressor?

That's the compressor. 4000rpm with 30psi boost is about 37 lb/min.

 

[Dougal]

To burn 150cc you're going to need 60psi boost. That's going to be rough on a high compression IDI engine!

Preliminary results, I still haven't nailed down suitable turbochargers:
60psi total boost. Split roughly 25psi on the big charger and the rest from the little one.
Total airflow at 5000rpm is about 70 lb/min (HX40 ain't quite enough).
Intercoolers have to shed over 110kw of heat.
Torque over 900Nm from 2000rpm to about 4500rpm.
Peak power around 360kw (480hp) and pretty flat from 4000-5000rpm.

I think the Fins/swedes/Norwegians let the motor Rev more, with stronger valve springs, up to 7k or so, and make more power that way. This would require less boost. No one would run those high rpms or high boost on the stock springs.

The Victor reinz oem head gasket for this motor is multi layered steel. That is one of the first things people replace, along with stronger springs, and substituting an intake cam from the NA om606 motor for better duration or something.

Yes muuris on youtube told me an hx40 would not be enough to burn 150cc. So already I was thinking hx52 or a big borg warner.

 

[Atg]

Also they let it burn at 15:1.

Maxypriest on std dynoed 450 using an hx40, but that was probably pretty smoky and hot.

 

[Atg]

I have been looking at retrofitting a dpf/catalyst with an electric burner, just for kicks.

 

[Dougal]

Anyone got solid info on the HE351CW or newer HE300 series?
