Mockup of dimensions of the FC unit, we are going to change quite a few things it looks. The FC unit will stick out an addition 3 inches from the engine flange, the to4 flange is going to be raise at the same angle and addition 2.5" and the wastegate is going to be redone. We are also going to push the to4 flange an addition 1" forward to make sure anysize turbine housing will fit. We plan on taking apart one of my T2's this monday/tuesday and getting more precise measurments and then we will start the process.



Comitatus, here is a t06 1.58 turbine housing pictured, you're turbo will definatly fit.

The addition 2.5" raise of the to4 flange will more than clear the frame rail. The duct tape is simulating the frame rail. Monday/Tuesday I will have a mockup on my FC.

Smaller 1.0 To4 turbine housing.

Ok cool....it looks like the additional inches will help out a lot for the FC's.



BTW...are these equal length runners?

very good question.

On the Fd unit they are not. They will be closer on the FC, but not by much. From the past several years I have been on the boards from what I have gathered it doesn't seem to matter. And with the space restrictions it can't really be done, if large turbos are used. I specifically remember RiceRacing I believe it was saying he didn't notice any difference, and I quote," the exhaust pulses come out like Mike Tyson". Anyhow at $500 a pop on the engine dyno, I currently am resticting to our models agaist current units on the market.



I am currently trying to acquire a crashed FC for mockup testing.

Got a progress reports on these?

Well I put the Fd manifold on my FC to figure out final dimesions. Still working on the manifold itself.

Im anxious to see how these are coming....

they are nearing completion of the FC unit last i talked to him. He is also currently installing a TO4S on a friends car with a HKS manifold on it, dynoing the car, then putting his manifold on it to see the power gains. Will be interesting to see.

I have to disagree with you on this. Rice Racing specifically said that it DOES matter that they are equal length. Actually it matters ALOT. That's the whole reason that manifolds like this are expensive it b/c people are paying for equal length. If it's not equal, then what's the point over cast? That is the point and it makes perfect sense if you think about wanting the energy pulses to be distributed at even intervals about the turbine wheel. Kinda like saying a bicycle would work the same if the cranks were oriented 90degrees from one another as opposed to 180.



As for not being possible? Again not true. My manifold as are many othes, is exactly the same length to within less than 1%. I can tell you this because it was computer designed. Now I understand that manufacturing tolerances will make this a little less... but a CNC bent tube will be very close to the original model so it's gonna be close at least with 5%.



I don't mean to crap on your thread, but I really feel that you are giving mis information here.



Respectfully,

I said from what I have gathered, I didn't say there was any proof to the statement nor did I say it was a fact. I do however plan on finding out on the dyno. No offense taken though, I too discourage misinformation, maybe I should not have said that..



Anyhow the FC unit is done, I will have pictures sometime next week.

Elziot what are u doing to meh baby?

I'm dying to see some graphs showing a side by side comparison of the difference in power and spool characteristics between a manifold with equal length runners and one without. Sure the logic is there but people act like its the determining factor between winning and losing..



The HKS manifold has a notch cut out to equalize the runners.. why?

yeh i wondered about that also



good thing u asked hehehe

FC3S prototype. Should have it on a car shortly...

...

....

....

im def interestee. It looks to mount int he same place as the ebay unit but much better build and design. I may have to upgrade to one of these. whats the price for them??

Looks good...Ive been eagerly waiting on these to be done...

Prices are $725 + shipping. They are all being sold with the heat rejection coating on the inside. If you read the entire thread you will see these units are far superior to anything on ebay.

does anyone have one of these yet?

So these fit on the stock turbo units on S4? I'm getting my BNR stage 3 back fairly soon and wanted to know if this would fit.

For a bit extra I could have a stock turbo flange watercut and weld it on in place of the to4 flange which its setup for. So yes I could make it work for you.

For an addiontional $25 I can do a V-band tial w/g flange also.

im going down there at the end of the month to buy one https://www.nopistons.com/forums/pub...#>/BURNOUT.gif

I have 5 of each done and coated in the shop.

A VW tuning shop verified more power at on the dyno at same boost levels, with coating both the inside and outside of their turbo exhaust manifolds. I now have 5 coated manifolds for the fc, and one for an FD.

I will have an FC and FD in the shop running both manifolds. I will have updated dyno sheets, with spool/hp characteristices outlines sonn...

What is the ID of the wastegate plumbing?

I'm still interested to see how well they hold up. Not saying many of the name brand manifolds IE: GReddy and HKS don't crack..they have been known to...but I'm just curious overall.

I'll let you know.

Yea, i saw your other thread...



YAY..test dummy, lol...hope you didn't pay much for it..he should be letting u do it as R&D and freee......

Well if you didn't read my other thread, its working like a charm. I also noticed temperatures near the exhaust manifold are significantly lower than the previous uncoated manifold.
