    So I am laying my hands on my first set of Mmp stage 3s. They look so impressive. They are beef! Mauricio does amazing work. I can sit here and talk for hours about the good however I want to highlight a few things I noticed and hopefully someone can pitch in with useful insight or experience. some initial impressions. and questions. the wastegate arms are barely open under no vacum and completly close at only 5 inHG. is this normal? I find it wierd since I am used to one wastegate action. Also. the waste gate arm has very little clearance from the compression housing it self. see pics for reference. anyone experience contact? a... any thoughts... ? these things look amazing. don't get me wrong. I Love em.

    Swapping out the naturally aspirated S85 V10 for an S63 twin turbo V8 in an E63 M6 is a bit of a shame but considering the application here is a dedicated drift car it makes sense. The twin turbo torque will certainly make it easy to get a drift going and those tires spinning. This swap is facilitated by Awron in Germany who makes various BMW electronics. They have data logging hardware, stand alone engine management systems, data displays, etc. Some very cool and high tech BMW hardware. This S63 V8 runs on an Awron engine management system. Unfortunately, the details are not posted on their website but they have a video showing their ECU running the motor which you can view below. Their ECU should make it possible for more of these swaps to be facilitated into other BMW chassis'. How about a twin turbo S63TU V8 Z4? Maybe an E46 M3? Anyone?

    Is this what you're looking for? I sure hope so. I lost many brain cells reading through that thread as well as a bunch of procede vs jb threads before it. The archives of BB are a cold, dark, nasty place....:hidingundercouch:

    It does, thank you! I will definitely double check though. ihernandez7910 is a very skilled mechanic. He is the Seattle go to guy for anything hardware on our cars. I'm sure he's already contacted Mauricio about the Wastegate's.

    bigdnno98, were you successful at finding an affordable car insurance policy? I live in Italy and must agree that the car insurance here is expensive compared to American standards. I use Genialloyd.it for three cars but just started looking for another insurance company. So, if you find a better car insurance for American drivers please inform me on this thread. Thank you in advance. ComoLake

    With engine design nowadays, the main restriction is the cylinder head and valve events. This is especially true in OEM forced induction designs. The cylinder head will always be the greatest restriction in a properly designed performance oriented engine package. In forced induction applications, the intake manifold's sole purpose is to ensure that a given volume of air is available when the intake valve opens. There is no real need to tune the pressure wave through the intake manifold port because the turbo ensures that the air is always there ready to enter the cylinder. But you can hurt port velocity with an intake design that isn't matched to the cylinder head port characteristics or cylinder filling requirements causing the turbo to work a bit harder...

    I could have sworn I talked about a stroker N54 with you?

    If it makes you feel better, my wg were spot on with my gcs but doesn't hurt to double check.

    Oh I see now you may need further fueling on top of your enhanced DI setup so maybe you will be doing tests with PI or meth.

    Great to hear you'll do front facing. It would be even cooler to do it with charge pipe meth. I know your DI means PI or meth injection is not important to you but many would like to know if airflow and supplemental fuel distribution is better on a front facing IM vs a stock centre entry IM.

    I'm just skimming this over right now as I intend to compile the results for an article but how many more manifolds still need to be tested and when will the testing be completed?

    Thanks for these results Tony, it doesn't surprise me at all. Your methodology is sound, and throwing out the highest and lowest really is the easiest way to set your error bars. As far as the IATs go, yeah I wouldn't expect the EOS to take a hit while on E85 due to "high" IATs. I know guys(different platforms) that are 240+ deg F with E85 and making 1000+HP to the tire. The data I've seen says high IAT doesn't matter with E85. The issue is getting it to light and keeping it lit so hot spark, gasoline timing, and .73-.75 lambda mixtures are making the most power. Nothing you've presented surprises me, and I actually expected the stock intake to hold its own against the aftermarket intakes. As far as EOS complaining, do they have their own data to present? If so, I'd be interested in seeing it. I've never bought an intake manifold without seeing real world data first, and the last intake I bought ran me $700 hahaha

    Could be your fuel injectors. I believe BMW has issued a TSB on the issue.

    Would be cool to see EOS V2 results if they would supply one for testing to see how it compares to the numbers they released (which weren't great but did move the power band over a little).

    Also I have heard EOS is now complaining on Facebook that I somehow stacked the data, and that throwing out the high, and low number was me trying to make their manifold look bad. The EOS manifold is already back on the car, we are very near the DI limits we feel, and will be testing some larger turbos soon, so the PI may be needed. The EOS manifold indeed weighs more, and showed slightly higher temps, but it didn't lose power, some TQ yes, but if we thought it were a poor product it wouldn't be on the car. No sour grapes over here, we just present the data, we do not manipulate it.

    interesting. Wonder if bmw did computer simulations during the design process to get the best flowing manifold?

    Edit. Nm. Had a closer look at the pics. I think they were welded wrong, the actuator end will interfere with them opening properly. Op, can you physically open the wastegates more?

    Since we're on the subject of Wastegate's, definitely want to do this before throwing in my GCs, Ivan. Those look really nice though. I hope it's resolved before installation. It's a good thing you brought this up here so others know to check before install.

    Where is Mauricio on all of this? Seems like he's had pretty stellar customer service. Pretty surprising.
