Do you still have your prototypes available? I need a smim. PM me

Thanks for reposting, i think it was down when I tried to look the first time.

That is insane, that companies never use a flow bench.
Thank you for your hard work and time

Re: SMIM Showdown! Lets figure this out once and for all!
 

I personally did not make the prototypes. However, after seeing what we did from all of this, we did design and make our own SMIM for my car. If memory serves, it flowed 463 cfm across the board, and a plenum size roughly around 4500cc's. It's been on for about two years now, and the only issue I had was a stripped bolt at the TB flange, because I apparently hemanned it on in a rush. I have also redesigned the entire NOS system, into a very clean rail style setup.

I wasn't happy enough with anything available on the market enough to buy one of them, although the newer style JMF race was close. We did find a somewhat simple solution to increase the flow to the down cylinders, and cure a good portion of the turbulence. However, we decided that making our own would be a good RnD project, as well as a learning expierience for me.

I would also be interested in looking further into the magnus cast pieces, although my initial impression is that it will have similar characteristics to there other designs. I was going to borrow one last year to test, but since we have now upgraded to a newer flow bench, I didn't want anybody to think the numbers were skewed, although we have used calibration tests to ensure the new one is within 1 cfm of the old. The newer bench also has much lower resolution, reading down to a hundredth of a cfm if desired!

I do believe I have all the materials still to make two more of the CNC SMIM's. I'd have to double check that, as well as pricing on one. If you or somebody else was truly interested, I could look into that.

Re: SMIM Showdown! Lets figure this out once and for all!
 

I'd like some info on this.

I must say the "yet to be named" and "REEF Race" look pretty similar.

Re: SMIM Showdown! Lets figure this out once and for all!
 

FTFY :)

That SMIM you made looks faaaaaancy!

Re: SMIM Showdown! Lets figure this out once and for all!
 

I'm not gonna lie, I really liked some of the things he did with his design. Especially in the plenum. It was the simplest solution I had seen, as well as required the least welding. Since that is one of the few things we don't do in house, it was an appealing plan.

The R.E.E.F. and this one look very similar, but internally, they are quite different. Dimensionally, they are different as well both internally and externally. Our manufacturing method is also worlds apart! We spent alot of time (6 months easily) just tweaking little things to get airflow exactly where we wanted it at varying loads.

Thank you. I went through a polishing faze! However, I wasn't able to do this myself with the equipment I had, so I sent it down south ot a guy that does show car and Harley stuff. He did amazing work, although I paid for it dearly!

Re: SMIM Showdown! Lets figure this out once and for all!
 

^You are right. I'm sorry for that you can tell just by looking at the pics, esp. internally where the differences are.

That nitrous setup pic gets me excited. Like I said PM me some info on the manifold when you get time. Its one of the changes I'd like to make to the car before next season, along with cams.

Re: SMIM Showdown! Lets figure this out once and for all!
 

Hate to clutter this, but if I were to make an intake manifold for my 2JZ, would you be able to flow test it? Just would be curious how it does.

Re: SMIM Showdown! Lets figure this out once and for all!
 

I don't see why not. I believe I already have an adapter plate made for the supra intake's as well. We did a few heads for somebody, and I believe we checked all their intakes as well.

Let me know when your closer to doing it, and well get something worked out.
