do you think my e55 amg w210, a little weaker engine, but i don't know the exact characteristics of its engine nor mine, mine 10.5 ratio comp, would have the same behavior with 2 gt45? When I am in wot (n / a actually) I have gearshifts similar to the mustang, between 4500rpm and 6000 rpm. I really want to go to the twin gt45, with spool after 4000rpm, without intercooler. Do not tell me that the gt35 is better, I just want to know if the engine behavior would be similar with 2 gt45, camshafts stock? please.

 

Only one way to find out. Please let us know how it works.

 

this is exactly what i think and what i want to do, i haven't learned anything from french forums, i just learned on american or english forums, with v8 ls. I will try. I am going on 80lb chinese injectors and 044 chinese double pump. 2 wastegate 38 chinese. prepa turbo extra low cost ... The e55 amg w210 in France is a really low cost v8 n / a. I have a camaro ls1, which is more expensive here.

 

Perfect, when the GT45 turn out to be too big like everyone here has already told you there will be one turbo for each engine.

 

Lmao

 

I got a mercedes w210 but e280 v6 2.8l 204cv ratio comp 10/1, autobox. I was afraid of breaking the 55 amg so I gave it a try with the v6.
I reversed the exhaust manifolds and made a ypipe (2 "pipes in a 2.5" y pipe in flange t3) The engine is stock, bosch 044 fuel pump.
I have a choice of injectors: 270cc, or 360cc or 440cc.
Turbo gt35 ebay t3 62/62. I have 2 wastegate springs: 8 psi and 14 psi.
I am at e85.
The knock sensors are disconnected, according to the Mercedes doc, it gives 11 degrees of delay on the ignition curve.
I no longer have a maf, nor an original lambda, i have just an afr aem. So the mercedes ecu no longer has any regulation for fuel or timing.
The boost piping is 2.5 "and 3" just before the throttle body.
3" downpipe with a short 3" muffler.
I am trying to adjust the fuel with a spa rrfpr on the return. If i can't, i will try another solution. Do you think that for 400m (1/4 mile) runs I need an intercooler? #ad

Yes. The air temp will be up from the moment it starts making positive pressure.

 

You need something like this.

ok thanks for the answers, i have a 2.5 "ebay air air intercooler. I can try with it.
My afr at idle is at 11, it's rich.
On low throttle he is 12.5-13.
I can drill the throttle to get a higher afr at idle, would that work or is it better to idle higher, can I also with a wedge to force it to stay slightly open?

 

Drilling the throttle plate will just increase your idle speed, then you are going to have to repair the drill hole. You need to tune properly, it sounds like you may not have the ECM set up for the injector size.

 

Any news? I have a few questions about your build:

1.What rpm do you start building boost on the E280?
2. What did you do with the vacuum lines/positive crankcase ventilation?
3. Isnt this turbo water and oil cooled? You skipped the water cooling? Where do you get the oil from?
4. Do you have any idea about torque/hp numbers?

Thanks
