NOTE: The Group Build is CLOSED. We are now waiting for ordered parts to arrive.
----------------------------------------------------
OK guys here's the deal. I am posting this a little early because CoolVanilla and I are getting a lot of PM's asking for details on the Group Build for Frankentake III intake units:
Yes we are doing a Group Build as a fundraiser for MFO#5 (with the blessing of the LXForums management, I might add... this is not a commercial venture). All profits associated with these units will go straight into the MFO kitty. Furthermore, anyone who buys a F-III unit is automatically enrolled in SXT-level participation in MFO#5. This gets you not only a Mods Face-Off T-shirt, but an entry in any prize drawings that are going to be available for MFO#5 contributors (stay tuned for that elsewhere).
OPTIONS:
1. Pick Red or Blue filter/gas recirc hose
(Subject to S&B getting their act together and shipping a blue filter when they are told to)
2. Pick 10" mk.2 or 12" mk.1 filter
3. Pick finish: Raw that you paint or polish yourself, or painted in your choice of color (subject to our being able to find the color at the local Kragen or Pep Boys). Note that you can do this yourself cheap and in an afternoon.
COST:
Base unit with 10" filter: $165 DELIVERED (no extra shipping)
1. Pick blue filter: Add $2 for the more expensive blue silicone hose.
2. Pick 12" filter: add $2 to cover the increased cost of the bigger filter.
3. Pick painting: Add $35 if you make us take the time to sand the sucker and then paint it.
4. Sanded only (paint it yourself): Add $20
WHERE TO SEND MONEY:
DO NOT send money just yet. Please use this thread for signups. I know some folks have told me absolutely they are in but please take a moment and tell me officially here. Use the following format:
Username / Color / Filter Size / Finish
We will contact you when its time to collect money When the remaining details are sorted out, CoolVanilla and I will take a Saturday, go into his shop in the morning and not come out until we have filled all orders.
WHAT ARE THE REMAINING DETAILS?
1. What tube will we use, exactly?
2. Can S&B ship a blue filter when they are told to or do they just ship red to everyone regardless?
3. What exactly will we use for the gas recirc fitting?
4. What are the exact dimensions we need with a 10" filter insofar as tube is concerned?
Item 1 is going to be decided on production time and cost. We have a line on a manufacturer who can do a steel tube for us with a welded-on gas-recirc fitting, but we have to see an example first before we decide if its viable. Item 2 remains to be seen when the 10" filter arrives (and the experience of others who have ordered from S&B direct). Item 3 will be decided soon, as I have ordered a wide variety of fittings (all of the ones mentioned in the F-III creation thread and then some) and will see what I can come up with that is functional and reasonable in price. Item 4, like Item 3, will resolve itself when the filter arrives, today or tomorrow hopefully.
So do you want a bigass intake that flows well, and was developed by members for their own cars? Don't want to assemble it yourself? Want to support the MFO series? Sign up!
Hey Matt, which version are you using and why?
All of this below should be very old news to people who have followed the development of this intake, as well as the earlier temp tests on Frankentake I. There is a lot of data in three or four threads that you probably should pay attention to and understand to be able to know why F-III is built the way it is.
So the answer to the question is: I am using the 10" filter, which I am calling the "F-III Mk.2".
The name is a misnomer. If you have followed Frankentake development you know I only used the 12" filter while I waited for S&B to deliver the promised 10" custom-spec filter (which never materialized). The 12" was the "insane size" that I wasn't sure I could even make fit in the first place, and which would be the last word in BIG. Since we knew bigger was better in terms of dyno numbers... well you can see where I was going and why I went there.
The 12" filter has a couple of issues with it. It is so large its rubber base sits on a rubber hose -- which is backed by a steel fitting directly underneath its base. It just so happens that by coincidence this is a perfect and solid support. Its almost as if it was planned that way. But the bad part is it keeps the intake tube and filter higher than it could be. This in turn -- coupled to its sheer length,which puts the filter base two inches closer to the engine -- contributes to warm air ingestion. Temp tests as reported originally seemed to be a problem, but after switching to a calibrated thermostat element in fact they are not so bad after all. Still they are not optimal, where optimal is 'ambient' and we know we can get 'ambient' across 100% of the filter element by using a 10" filter sitting low on the silencer shelf (and it sits low because the shorter filter clears the above-mentioned fitting, thus allowing a longer tube).
So if the temp isues are not serious with the 12" filter, and it works well, why argue with success?
I want perfection in terms of incoming ambient air. My original configuration, which took the unconventional step of doing away with the heat shield, relies heavily on the existence of the ambient air pocket that is present for certain if you make the simple mod of removing the lower radiator baffle (or, optionally, both of them). The base of the 12" filter sits at the fringes of this pocket, and while it was shown to perform well on the dyno, we all know that ambient air is better air. PLUS, I believe we are very likely already using a filter that is big enough with the 10" element. Going from 10 to 12 may not be better. We will know for sure after MFO5 but based on experience we should be fine... especially since the 10" filter is STILL substantially bigger than any other filter on any other LX intake on the market.
Is there anything wrong with the 12-incher? No. And it will for sure be a conversation piece when you pop the hood. And it will for sure be the highest-flowing filter you can put on your car. Not unless you saw a hole somewhere and run it out of the hood or the fender.
