Twincharging the stock turbo
Twincharging the stock turbo
Just a quick question on this, I have a GT45 sized turbo which I will be looking to fit at some point to my E300 OM606.962 - this would require a few more mods around the manifold, exhaust, oil lines etc. I was just thinking about perhaps using the stock turbo but twincharge it fitting a supercharger where the aircon pump currently resides - the air con is currently non functional and I am currently removing the pipework.
I know that I can't really run a small supercharger and the larger turbo as the airflow wouldn't be great enough to supply the turbo, however a smallish supercharger and the stock (undersized) turbo might be an interesting combo. I am looking at something like the Eaton M45 supercharger and using the manifold etc from the SLK (keeping it Merc!) - not sure what PSI these usually run at but if at something like 8psi this would give a nice increase in boost and airflow to the stock turbo.
Should I look to try and fit the supercharger and twin charge the engine with the stock turbo or simply wait and fit the GT45 sized turbo?

It also depends on how you plan on routing it, do you mean you want to compound the m45 with the stock turbo, or will you be going for a sequential setup?
Not sure if the compound setup has been done but if you read through a bunch of threads from a few years ago there was at least one person who attempted a sequential setup with decent results.
M45 is tiny. You want a M112. But if you're just going for the stock turbo it might be a decent match, that way you can upgrade as you go along.

Hmm I will have a think, the M112 superchargers aren't the cheapest considering I do have a large turbo to bit fitted, might just go with a larger turbo instead and keep it simple. The stock turbo is still using the vacuum wastegate so I might look to change that over if I can and run slightly more boost in the mean time.

(11-18-2015, 06:12 PM)CRD4x4 Any reason you're not considering an M90?
Because superchargers that aren't an M45 are rare in the UK, hardly any cars are supercharged, small turbos are usually the way to go for smaller displacements so that there is no parasitic loss. Will just stick with the larger turbo route

Sourcing M90 superchargers for under $150 is pretty easy around me and they arent too heavy (my bathroom scale says mine weighs 28 lbs).
Just sayin.

Just checking Ebay, there aren't any in the UK only the US, the cost of the shipping costs almost as much as the supercharger, will just go for the large turbo as I already have it - wasn't sure if anyone had tried to twincharge the OEM turbo on here.

M45 and stock turbo are too small for a 606 unless you like your steak well done.
Installed:
OM606/722.6, big IC, W220 brakes.
Planned:
DIY manifold, compound, 722.6 controller, built IP.

M112 came off mid 00's jag and available for about £200 here in UK.

I have 165mm wheel on the crankshaft and 80mm on the supercharger.
I have 0.2 KG boost on the idle, and really really quick responding engine and boost,
Max boost is about 2.1 KG,
The setup works reaaally good, much quick and fast power.

0.2 kg on idle, QUICK boost and respond, big intercooler, 3'' pressur pipes, 3.5'' exhaust,
Std 300d automatic gearbox, with harder shiftning,
4th gear wheel spinning without problem..
Still much to do, fuelpump, harder suspension, metall and paint inside the enginroom,..
