A day that turned into a week, on the flow bench.
dave the magnus intake your talking about is it the cast v5, street smim, or the race smim. ive been looking into getting the cast one but now im thinking that getting your ported stocker and using the money i save on the IM on your double pumper...
magyar86, the intake of Magnus's that I am referring to is his new cast one, the 5L or something, the only cast one he offers.
The results from many different people have been very good on it. I'd like to try one out but have not because I think it will cause to many problems. If he was behind me trying/buying it I'd do it or even have a 3rd party do it on my car but I'm not going out of my way to get my hands on the part and having more problems because of it.
I'm pretty into this project of mine so it will be interesting to see where it goes and how much power it gains or loses.

On the note of side entrance vs. centered entrance... it's harder to get flow balance, but it still can be achieved with a HUGE plenum.
Dave,
make a tiny plenum and then make a huge one and dyno them back to back. lmk what you find. Also what size TB are you using?

I am using the stock 65mm TB. I am starting with a plenum that is about 230 cu in. I will be cutting it down from there in size.
The DI intake has one of the largest plenums (I think), side entry and very close to perfect balance on the flow bench. The V2 has the largest of the plenums of all the stock intakes we tried and has very good balance too. The intake we ported/welded actually had the best balance of all on the flow bench but the plenum was very close to stock sized. We only dropped the runner length about 1".
I need to set up my car with EGT's or individual AFR's for each cylinder to find out what is actually happening on the dyno under pressure.......I won't be doing that though. Before anyone asks why, I do not want to ruin this header with sensors, I am too lazy to wire it all and after testing 10 intakes on this car I feel it is either going to make power or it isn't. It's the trial or error mentality I have I guess.

Nice write up 
i think ross machine should have everything you need to get going.
If time & space permits, a long runner manifold utilizing your expandable set-up as you talked about in a earlier post would be awesome.

This thread has evolved quite a bit from the first few posts, but I was thinking that it would have been very interesting to see how a completely stock IM stacks up against the three IMs that you originally tested.
I did the bone stock intake/tb testing last year about this same time mrfred. I am 100% confident it will lose a considable amount of power up top and still have slightly better low/mid range than the ported unit.
The car with the standard BR ported intake and 65 mm throttle body is still down about 15 whp at 4500 rpm over the stock one with the stock TB.
My car is back on the dyno this morning to run the stock ported intake/tb out to a higher RPM to try and cross reference this intake to the V2. The V2 results should be higher looking at the sheets.
Then we are pulling the stock ported unit off and will start working on fitting the sheetmetal into the car.
EDITED:::
This sucks. I was just looking through all my dyno notes and sheets, I needed a dyno sheet with my current combination and the V2 on the car going over 8500 rpm so I had something to compare to. I don't have a single run going higher than that, I've never run the car like it is over 8,000 on the dyno. That will leave just comparing high boost (42 psi) up to 8,000 rpm on the this intake VS the V2.......results within the hour.

OK, I made some pulls on the dyno. At the same 30 psi I tested at last week the car is up on HP and TQ in the low/mid range compared to last time and the same up top. I just wanted to get a baseline and compare it for weather differences.
Now a few things I want to be clear on. The dyno sheet you are about to see shows three runs. The first solid line is my car and how it performed typically on the V2, on a good day it was in the 675 whp range. This can be verified by looking back over my old posts etc., for anyone who wants to do that. Then a few weeks ago I was going the SD muffler testing and the car was an absolute freak and put down 694 whp which it had never done before. Everything about the run was better than ever before. That happened one day in all the time I have spent on the dyno with the car. Since I used those graphs last time I showed what we were doing I am including them. Personally, I feel they have to be dismissed as it was COLD as hell the day I did that testing and the car never performed like that before or after that day. It is the best ever so I put it on the sheet.
Then today's runs were right in line with last weeks so I feel today's results of the BR stock ported intake are right on the money.
The details and I am sticking to what I see typically to what I saw today.
The V2 makes more power at higher boost/higher horsepower than the standard port work does.
The V2 on a typical day compared to today is up by 11 whp and 7 ft lbs of torque but still has the losses in the low/mid range as it does at 30 psi.
If you put the freak day with the V2 into the mix the low/mid is exactly the same (which I know is impossible from running it so many times) as the stock ported and up top makes 18 whp and 18 ft lbs more.
I've given the information in full, do what you like with it. My opinion is the V2 is better at this HP/boost level (41 psi/700 whp) over 5800 rpm and by a maximum of 11 whp and 7 ft lbs at 8,000 rpm. Because it does have gains from 5800 rpm and up the car would be quicker/faster in the 1/4 mile with the V2 over the BR ported stock intake. Now keep in mind it is a completely different story at 30 psi and 600 whp at those levels the BR ported stocker wins out by a higher margin and across the entire RPM band.
Here is the dyno sheet:

nice finds, now all we need is for you to come up with a mani that can top the stock ported at 500-600whp and can top the V2 at the 650+, seems like a almost impossible task to get a mani to make power at low rpm/high rpm and lower hp/high hp but i have faith!
Dave,
Have you considered setting up an intake manifold like the old dsm cyclone intake ?
by incorporating butterflies into the plenum, you could increase spool characteristics as well as increasing the flow up top when the butterflies open completely .
Once again just a thought.
