devan Posted September 13, 2009 Share Posted September 13, 2009 Its behind the one that you can clearly see, i think. Does look like one turbo, but think its two. Quote Link to comment Share on other sites More sharing options...
Wez Posted September 13, 2009 Share Posted September 13, 2009 Its behind the one that you can clearly see, i think. Does look like one turbo, but think its two. I dont see how, the exhaust housing is there and then you would have a resonable sized downpipe behind that, I dont see any room for another unit that size unless its tucked out of view some where Quote Link to comment Share on other sites More sharing options...
Scott Posted September 13, 2009 Share Posted September 13, 2009 I'm assuming its just underneath the one you see. Ahem... metal bit, under the first turbo. Looks like the top of a 2nd compressor housing? Quote Link to comment Share on other sites More sharing options...
TwinTurboM3 Posted September 13, 2009 Author Share Posted September 13, 2009 shoot 8F was chosen to preven wheel spin 2 years ago. we solved the wheel spin issues and since then I run all time in 8F. BTW turbo is there under the hood. Just to give a clue, a single 66 mm turbo wont make 941 at the wheels alone. And the 941 is at the wheels not flywheel.

To be honest i did previously but i thought i would give the benefit of the doubt. Do you not know where the 2nd turbo is well enough to explain in relation to the first?

TwinTurboM3 Posted September 13, 2009 Author Share Posted September 13, 2009 3 cylinders feed 1 turbo the next 3 fee the other turbo. very easy to think. very difficult to locate under that tight space. Quote Link to comment Share on other sites More sharing options...
Wez Posted September 13, 2009 Share Posted September 13, 2009 Can you not just post more pics clearly showing the 2nd turbo, the intercooler pipework for both turbos, both air filters, and dual wastegates with the downpipe connections Quote Link to comment Share on other sites More sharing options...
jevansio Posted September 13, 2009 Share Posted September 13, 2009 Is the 2nd turbo feeding the 1st? (compound charged) Quote Link to comment Share on other sites More sharing options...
JamieP Posted September 13, 2009 Share Posted September 13, 2009 Hi Mert, First turbo looks to be infront and below the other one? Quote Link to comment Share on other sites More sharing options...
jevansio Posted September 13, 2009 Share Posted September 13, 2009 Are the feeds off the FMIC endtanks so you can check the pressure drop across it? Quote Link to comment Share on other sites More sharing options...

Chiefgroover Posted September 13, 2009 Share Posted September 13, 2009 well done on turning an uninspiring car like an M3 into a monster:) obviously someone is good at custom fab to get that other turbo stuffed in there so low down. Quote Link to comment Share on other sites More sharing options...

pistonbroke Posted September 13, 2009 Share Posted September 13, 2009 Why are the 'M' series inline 6 engines at such a funny angle? If it was straight vertical like the 2jz, then you'd have much more room to play with on the exhaust side. Quote Link to comment Share on other sites More sharing options...
JustGav Posted September 13, 2009 Share Posted September 13, 2009 http://www.da-motorsport.com/damotor02.jpg A nice looking car that is for sure...but still can't work out the 2nd turbo location. Quote Link to comment Share on other sites More sharing options...

TwinTurboM3 Posted September 13, 2009 Author Share Posted September 13, 2009 Can you not just post more pics clearly showing the 2nd turbo, the intercooler pipework for both turbos, both air filters, and dual wastegates with the downpipe connections want to keep that part confidential. I do the fabrication and pipe work by myself. Is the 2nd turbo feeding the 1st? (compound charged) Nope. Both chargers flow at the same time, parallel twins. Compound has been on my agenda for my E36 M3. However, I gave up compound charging as it would require a lot of testing. I never did it. Diesel truck owners do it successfully. One big advantage of compound charging is that it is spooling faster than parallel charging. I have solved the spool issue by spraying nitrous oxide where the engine needed, from 4000 to 6500 rpm and turn it off at 6500 rpm. Just to aid spool. Are the feeds off the FMIC endtanks so you can check the pressure drop across it? Yes, for measuring pressure drop. For feeding wastegate ports. As this is a amateur, hobby project, pressure drop/back pressure drop/temperature drop should be datalogged. Yeah, thats what it looks like to me. Thanks. Looks great, alot of work gone into that. Well done. Thanks. You could have saved yourself a lot of development work and just bought a Supra 1- I love Supra very much. 2- If I would buy a Supra, that woud be an alredy proven project. I could add little from myself. With the M3s I spend time and energy and it makes me happy. Its not just to own and drive a fast car, to design the system and tune the electronics. 3- Faith: I believe in faith. I bought my 1st M3 11 years ago and it is also turbocharged. It all started with the E36 M3. I could have bought a Supra and worked on it. Why are the 'M' series inline 6 engines at such a funny angle? Slanted angle enables a big oil sump to be used. If it was straight vertical like the 2jz, then you'd have much more room to play with on the exhaust side. Yes we did a vertical engine project, where M3 engine was vertical to the ground, was able to put a Gt4788 easily. gave up, as I dont like the idea of dry sump. http://www.da-motorsport.com/damotor02.jpg Thats the same car after nitrous oxide kit is custom installed. A nice looking car that is for sure...but still can't work out the 2nd turbo location. 2nd is low down. Quote Link to comment Share on other sites More sharing options...
