I know I had to run a pump on my e36 with a steedspeed and 4094 in addition to a 6765 precision bb. I currently have a bb comp turbo that I just tried running with a tiny restrictor and optimal drain and it is getting a small amount of oil in the charge pipe. With a MAF based system you don't want any oil to contaminate the HFM.

I would love to see pics of the Saad manifold. I am also curious to see if there is any oil in the charge pipes, even minimal amounts. I am always open to other options. Trust me, I was shooting for a lower price point, however I want to offer a high quality, trouble free product.
Solid info, and absolutely agree about oil in the charge pipe not being acceptable. I was just curious if HPF had maybe done it so there would be zero chance of issues (and then priced high and marketed it as "perfect" more or less).

I don't think it matters on the HPF kits as they run an AEM stand alone and do away with the MAF altogether. Oil in the charge pipes is much less of an issue on a MAP tuned system. However, utilizing the stock DME to keep costs down and simplify the whole kit requires keeping the stock MAF configuration as well, they go hand in hand... DME=MAF.

If any of my understanding is inaccurate in any way please feel free to correct Mike/John.

Can't you run an alpha-n tune with the stock DME?...

That's how Evolve does it for their CF airbox (no MAF).

Which would mean you could, technically, do it with a turbo system.

I believe ESS Tuning uses Alpha-N for their E46 M3 kits as well.

You can run alpha n on a centrifugal setup, however a turbo car is a different animal. You can't map the car properly using only alpha n because boost isn't linear to rpm like in a supercharger. You can be at 8 psi at 4k rpm or 2 psi at 6k rpm.

I will be away this week on vacation, however I hope to get some updates to the thread as soon as I come back. The car is up and running great so it is time to get it back to Nick for final tweaks.

Nice! Good information. I'm looking forward to some future results. Have a fun and safe vacation.

I'm familiar with MAF and MAP based turbo systems. I'm designing my MAP based system now, and already ran a MAF based system.

I'm not ok with seals leaking, it can cause them to erode and fail prematurely. Also, the oil getting into the compressor doesn't really help anything, it makes any dust that gets through stick on the charge pipes etc. So its still not acceptable to me with MAP.

Well i can always agree with that, oil in your charge pipe(s) is generally never a good thing or sign. Just that it'll 'foul-out' a MAF based system far quicker than MAP based one by the very nature of how they (specifically the MAF) interpret/read the airflow volumes..

Air/oil Sep will solve those oil issues...

Only if the oil is coming from the crankcase and not from the turbo oiling system.

Question

Hey Mike (or John), not to sound sarcastic but is this kit gonna be a 2011 thing? I feel like a psycho stalker constantly coming back to visit this forum solely to see if there are any updates lol... It seems the rate things are going with this we're realistically looking at early 2012 before the kit is ready to be sold and actually delivered. Would i be correct with this? Thanks.

I never said or suggested anything less, I'm simply looking for a 'realistic' time line on availability for a variety of reasons. I think i speak for a lot of people interested in this kit as well. Also, it puts less daily stress/pressure on the company looking to release such a product becuase everyone's on the same page. Actual performance numbers haven't even been released yet and i doubt they will until the final/minor tuning glitches are eliminated/complete. Only then will production of kits even begin... so when i say ''are we realistically looking at it being a 2012 release thing'' its pretty accurate in the scope how long such endevours usually take. It also allows prospective customers to begin budgeting for the release of the first batch of kits now rather seeing if/when it may happen... if its Jan/feb 2012 just say so, and we'll save up and lay off till then, thats all..



Mike, is the car back in Nick's hands for tuning?
