When 500whp just isnt enough...
I am done with this lame supercharger. Its time to go twin turbo. But I need some help. First, I need some information regarding stock internal engine parts and materials.
1. Does this car have a MLS head gasket?
2. Are tooled steel headstuds, mains, and rods made by ARP , a1, or any other fastener manufacturer? If so, who?
3. Has anyone tested the Rockwell strength of the rods? I know they are forged but how tough are they?
4. The pistons are hypereutectic pistons with a cr of 9:1 correct?
5. What size twin turbos are the turbo guys going with? I am HTA 35rs from Forced Performance.
Marco from Magnus Motorsports will be tuning the car. It will run on E85. Air to airfmic. Something similar to what the gtr guys are using.
Anyone got anything I need to look at specifically or for see a problem with the plan. Production for this project starts November 1.

I would say just hold on a couple more weeks. RBJ and myself have some money and time tied up in TT builds and very soon we will know if it is actually do able. It is all going to come down to tuning. In the next few weeks we will know if the tuning is a possibility. If it is then this opens a lot of doors. Once mine is completely finished I have no problem sharing plenty of info on the project. Wont hold any info back
As far as your previous questions you asked about the stock internals etc. If you do a little bit of searching you will find the answers to all of them.

Sounds exciting!
1. Im quite certain our head gaskets are MLS type.
2. I doubt any of our stock hardware is made by ARP. They also have torx bolt heads so No.
3. I doubt you will need to change the rods, just replace with ARP rod bolts would be a great idea.
4. The stock pistons are cast and have a dish design yes 9:1
5. Twin GT28's can get you an easy 700whp and be very fun to drive. Twin Gt30's would net about 800whp. GT35 although will make more power up top. Will come with a lot more lag. Depends what you plan to do with the car and driving habits?

I love GT35Rs. They are an awesome turbo for 3 L engine cars.
Might find it's slightly short of breath low down on ours with a pair of these. Maybe smaller A/R would work. Plus these would be overkill for stock internals.
28s seem too small, I think you'd choke the exhaust up top and smoke the tires down low.
30s or T3 seem about right.
Some nice tial exhaust housings will help fit turbos up in tight spots and look nice too
Wonder what happened to Speeddriven's promise of turbo ...

You can get ARP bolts for the stock rods from Brooke/Shardul, they had some made and probably have some still for sale.
I don't have a Rockwell anvil handy but I just grabbed a stock rod off the bench and bit it really hard, not a mark so I think you're good to geo
The stock compression is in the 7.7-7.8 range with hyperujunktic pistons that are fairly durable IMO, they have a very thick upper ringland but run the mix lean/too hot and they pop like a cherry.
+1 on the "you should wait"
See what these other guys come up with, and learn from their experience rather than waste time building something that ultimately may not work.

Im in agreeance that 35r might be a big pair. Honestly a pair of 50 trim t3/t4 turbos would probly be amazing on our cars. The 30r seems to shine at much higher pressures, pressures I dont think we would really use on our cars. 16-18 lbs with 50 trims would probly be amazing.

I have a 35r on a 2 liter motor running 32lbs with E85. Our cars would effectively be like 2.25 liters and thats not really enough of a difference. My car really gets going at 5k with a .82 A/R. in 3rd my auto is 1:1 and under a load will make around 25 lbs by 4200 rpm. Granted we have way more torque off boost than my car but still. The other thing is throttle control is a pain in the *** cause you can be giving only part throttle but when you hit the boost thresh hold its still yanks pretty good. Less of an issue in my AWD car but could make for a squirly rwd e55. Regardless a twin turbo E55 will probly be a hellraiser.

50 trims are great turbos but I think they are too small for the displacement. Plus they don't have billet compressor wheels, if you are referring to the standard Garrett t04e/t3. I appreciate your service, but this project is going forward regardless of other folks results. It will be interesting to see others results, but quite frankly this platform is way behind in terms of performance. Several major players are interested in the e55 for product development as an alternative to spending money on a supra gtr etc. These cars can be had relatively cheap in comparison to other cars that don't perform as well in almost every aspect. The supercharger is an inherent problem. So much so that Mercedes themselves moved to a different method of boost. Thank you for the feedback.

The only reason I went 35r on my eclipse was I needed that 2-400 rpms sooner threshhold. It helped very little and cost nearly 2 times the price. Perhaps the 2 grand in savings might be better spent on some thing more tangible.

If memory serves me correctly, our stock comp is slightly lower than claimed by AMG of 8:5:1. Also the stock rods weak link is the bolt. On a good tune blower setup, the stock rods would not last very long above 620rwhp. E55amgrocket had them tested a while back. I also have the part #s from arp for our rod bolts.

we always are. Plus its not our first turbo AMG conversion...
right on the money....
