....excuses, excuses! hahaha! Just giving you a bit of grief man! Will be standing by, love what you are doing...keep it up!

Anyone knows where i can find some decent plug cables for the M112 engine ?

Thanks.

 

you can buy a set on our website...

 

Guys that are doing the turbo, a quick question, how u guys plan to put the hose that goes back from the intercooler to the MAF. are you going to use the original engine cover and just bridge it at the end or u guys are fabricating something ? there is not enough space on the MAF sensor for me to secure a hose properly, not enough space to clamp ... thanks.

 

neat project but there will likely be some nasty boost lag having that much piping etc.

 

Guys over there, what A/F Ratio are you going to get the car to run at, my E240 has petty much stock N/A Engine internals, with kleemann running the supercharger boost at 0.5bar, i think i may only run the turbo boost at roughly 0.35~0.4 bar, as u know turbo boost is much more efficient then supercharger boost, i may want to keep everything safe. Also now i have a headache is should i run a air-air intercooler or a water-air one . Plus another headache i have is the oil pressure enough to cover for the oil return of the turbo, or i may need another oil pump. Also if u guys know of any small wastegate that opens at roughly 0.35~0.4 bar , those tial is 38mm and its too big for the pact area at the bottom, Any suggestions ? Thanks.

 

Very impressive, that’s the Best Turbo rear mounted system I have seen, makes this one look like S___. Great Job.

 

This has shown not to be true on numerous similar projects.

 

Powermod ecu wired on my E240 today. i am able to control ignition timing by using crank +ve and -ve also 6 injectors. This piggyback is also able to control boost by rpm which is usefull for me.

This weekend i am going to book the dyno and put in a base map for the N/A engine in it, run it for a week, then redyno and see if the ecu readapts itself or not. This is a intercepting piggyback unit, running its own map sensor and not a unit that cheats the airflow though.

After i am done with this then its time to bring the engine down, since i am having the M112 engine as well i am thinking to make this project big. Probably C32 crankshaft/conrod/bearings and pistons . the 2.6l and the 3.2l (N/A) has the same partnumber for the head, so i figure it should be fine. this way the engine should now be stroked with c32 parts, i am confident the c32 conrods should be able to handle 1 bar boost. If anybody have c32 original camshaft/conrod/crankshaft for sale, please let me know.

Thanks.

 

...........what year is your car that has the piggy back system?

Ted

 

2004

that unit is from powermod.com.au

 

Well after all is said and done I'm wondering how much the kit and install will cost, Looks like a BIG job. Wow!

 

......thanks

Ted

 

Well the kit was said to cost $5200 but as for install well...

 

$5200.00 is a good price ,but as a DIY ,WOW! LOL!

 

hmmm...updates?

 

Photos , taken with my lousy phone camera

a photo with the software running,

a photo of the ecu wired, but the ecu is hidden in the cabin, once i finish my whole project i will get a cam and take better photos :P

 

Updates?

 

no idea about LET, but i have an update on mine, As we have the hot tropical weather here, the oil cooler for engine and transmission which is inbuilt to the radiator is no longer practical , for transmission wise, its currently being replaced with a transmission cooler unit from bmw e60 530i, small enough and there is just a good nice o space to fit it, between the air-air intercooler and the radiator, a radiator is being custom made right now, my car originaly has a single core unit and we feel we need a twin core unit, as for the engine oil cooler, we took of the mercedes oil cooler housing, machined an adaptor, and currently fitting it with a japanese type toyota oil cooler , blocked the water hose that cools the engine oil, and then we route it to a air-air unit as well using a HKS oil cooler core which is relatively short and longer in length (just nice for being feeded with air directly from the amg front bumper. "bear in mind i am working on a W211 E240", the powermod ecu i had works, originaly this engine makes 177hp/260nm on papers, on dynojet stockm it made 142hp/203nm , its runing relatively lean , like 14.7 in closed loop and in the end of 14's during full throttleon the high rev section, which we all feel its Lean for our fuel here, we only have 97ron. We got the vehicle to run 12.8a/f ratio confirmed with dynojet and motec wideband throughout the high revs, and advanced the ignition by quite a bit and end up getting 154hp/215nm on wheels with great pull on the mid to high range, so now the cars feel lighter as well, tested it out for quite some time, thrashed it around, and no check light, so i think this ecu is good to go. The manifold is still being custom'ed right now, after that we need to do pipings and so on, i am using 2 units of dual ball bearing from the s15 silvia, its a great unit capable of doing about 260hp at about 1.2bar, but obviously i am going to run it at about 0.8bar , longer life for the turbo as well. the original actuator will be retained, and a haltech boost control solenoid will be wired to the powermod unit to control boost by rpm/gear. The problem i have now is finding a suitable intercooler, as space down there is quite limited, due to the not so tall opening at the bottom of the amg bumper, i need to find a long and short intercooler good for running twin turbos, i.e down flow intercooler which is not so popular here, so i may have to search from other countries, The material used for the manifold and the downpipes apparently to be shedule 10 , or whatever they call it, cause thats what the shop name it, 3mm thickness. 2 unit of bmc carbon dynamic airbox would be used as the intake, utilizing the original intake area from the vehicle and feeding it through the airbox directly to the turbo, open pod should be better but i want quiet, hissing sound would make the one on the passenger seat scream at me. technically there is enough space for low mount turbo set up on the w211, but thats the other story with w203 though.

after the pipings/manifold/turbo bolt on/oil return and so on its done, the whole engine will be taken apart to see what we need change, conrods/pistons is a must, but now i worry the aluminium engine block wouild not be able to take the boost, so i would need to get some good piston sleeves as well, meanwhile we are still deciding which compression ratio to run at as we do not want to sacrifice low end too much, u know the vehicle will still be daily city driving with extra power when we need it. after discussion i am keeping the cc at original 2.6 and just boost it from there, hoping to get a 350hp on engine, u know kleemann made 260hp on engine with their supercharger at 0.5bar ? this is ball bearing turbo boost we are talking about :P

we are also thinking to relocate the ignition coils as its just too hot in our weather here.


Wish me success guys, no photos until the thing is nearly done.

 

I can already forsee the sales for the "V12 Bi-Turbo" side decals to go up on eBay.

Edit: Oh and subscription added.
Edit 2: Do you gentlemen believe that once the finish product is available for the public that you'll have any issues with the computer giving out faults like SOS, etc.?

 

haha
decals or emblem is not something i like

my car has no decal :P

now i am still thinking, should i just use the conrods/pistons/crankshaft from the c32. its designed to handle boost.

 

sorry for the long absence guys, we have been swamped with orders, phone calls, working on cars and I am trying to get everything caught up because my wife is going to go into labor anyday now!

BUT, i have a new update for the car...I have decided to change the design of the turbo project...i will post up some pics for you tomorrow, but it is going to be very interesting...

 

Congrats in advance on your child that awaits...may God bless your new born when it happens....

 

That’s fantastic news, Erick! Congratulations!!

We’ll cut you some slack this time...family before cars is okay by me.

 

Amen to that+

I can't wait for the update either. Turbos ALLLLL the way!
