Front Facing Intake Manifold Flow Numbers and open to orders...

[sethron71]

Alright as I posted a while back I converted the stock plenum to a front face set up. I dynoed last friday and made decent numbers 441whp and 443wtq(only a 4800rpm pull due to fuel cut)
Dyno sheets here:
http://supraforums.com/forum/showthread.php?t=298899

Flow numbers are in. Done on a SuperFlow SF-600 flow bench with FlowCom and WinFlow.
Bone Stock Turbo Manifold (used to get a base line on the machine):
220.9
223
205.2
210.7
211.7
221.1

Stock Turbo manifold with just my conversation, no PnP or anything just TB moved to end and old hole blocked off(my personal manifold):
232
224.7
227.5
236.3
239.8
227.4

I will be PnPing mine and testing it again within the week.

I am now open to orders:
Way it will work is you email me telling me what all you would like done to your manifold and I will send you an estimate invoice that lays out the costs and a gives you a very close estimate.

Options available:
-Standard conversation - $250
-Port and Polish internally - $150
-Polished housing - $150
-Alternator Drop down bracket - $100
-Throttle linkage brackets - $75
-Plus all will be subject to S&H and a cleaning fee - $45.
(Prices may vary slighly with time if you email me with a request I will send you an estimate that assures you the prices on it if you order within one week of the issuing of the estimate)

Also available - one off short runner manifolds! Email for pricing

Email me at sethron71@yahoo.com with requests.

My goal in this entire project is to be able to cost effectively convert your manifold to a FFIM setup to increase throttle response, reduce heat soak, and clean up the engine bay.

The order of how these are done will be based on who can provide their manifold first or whom ever has an extra one. I have one manifold on hand that will be getting the conversation right away and then the first person to order will be able to do whatever add ons they would like. First two customers will receive a discount due to prototyping yet the quality will not be suffer because of this! :bigthumb:

He are pictures of the very first one I have made, my own:

Things that will be changed from that are it will be all one aluminum tube from mani to throttle body mount plate. My mistake forced me to put in adapter. Better throttle linkage set up, old throttle body hole welded shut not just blocked.

Let me know and I will hopefully get some manifolds going. Also if you would like a full custom one, not utilizing the stock plenum I can do that as well.

Thank you for your time,

That is awesome to see! I'm glad you got numbers! Maybe that will spark some people and get them to buying! Once agian Great news and Great fabricating!

[awsom-0]

thats sexxy! really cleans up nice

[GrimJack]

Interesting information! Some numbers work nets this...

Flows 7% better than stock
Flows more regular across all cylinders - stock deviates by 4.8%, modified deviates by 3.6%.

Sounds like quite the enviable mod to me.

[mdr40z]

looks great! what ball-park bucks are we talking?

[CTsupra]

Oh damn!

I thought this was another "can i use a mkiv ffim on my car thread", and didn't bother to read it!

Good job!

[Bigdough666]

PM me a price about this mani. I have an extra one jus layin around, might as well use it. Thanks.

[mkIIIman089]

Wow, looking liek a much more practical way to do the FFI then totally remaking an entire manifold. Like others I would like to know a ballpark of what something similar to what your personal one is like.

[Steve_N]

Great job! Very impresive.

[Blue87T(Dan)]

Very cool. For the basic conversion would everthing needed be included to get the manifold installed and working (not referring to IC pipes of course) or would other fabrication have to be done to move the throttle cable so it works properly?

Dan

[sethron71]

Thank you all for you interest and encouraging comments. My first new version will be out Monday and I will post pictures at that time.

Great.

One key to a successful business is answering the questions posed by possible customers. You didn’t answer any of mine nor many of the others asked in this thread.

Unless your prohibited by SM do so please give the details we requested.

[Justin]

great product, how much!!! :)

have you thought about instead of blocking off where the old intake was on the upper manifold cutting the extra material out and welding a plate on so it looks nicer instead of having hte obvious block off? if that doesn make any sense which it certinally may not, I'll draw a picture when I get home :)



APARENTLY its posted already, about welding the plate on instead of blocking off so don't yell at me :)

[CTsupra]

^ makes perfect sense to me. i was just about to ask the same question.

[GrimJack]

Unless your prohibited by SM do so please give the details we requested.

Not that I am aware of. The only restrictions we've placed on people are for group buys - you need to get approval first, not that it's very tough to get - and occasionally we've banned someone for being an asshat. This is hardly either case, so post away.

If you are going to openly attack me on my own post you should think first. I am not here to attack but I do not like you making assumptions like that, yours was the last question yesterday and I PM all others with answers I had just not gotten to yours yet. Also I specifically requested that all questions be PMed or emailed to me for this very reason because it is very very hard to go through all the threads and posts and respond to every question. So I would greatly appreciate your patience.

Thanks,
Seth Ingham

Justin,
I know exactly what you mean and I have toyed with the idea. The only catch is the whole entire point of this is to have a stock appearing very inexpensive conversation. I can do that no doubt if you would like that done on yours but a lot of the people are going for the fairly stock appearance. If you were to eliminate the EGR tube and cut the ISC tube back you would be able to take that whole section out and replace it with a sheet, I have definately thought about it and can do it. I will edit my post and make it more clear that custom ideas are welcome they just drive the price up so if people are willing to pay for it I can do what ever they want. Thank you for your interest and intuitive questions.

Sincerely,

Do you lose the ac with this conversion? I don't see more than 2 in clearance between alternator pulley and the electric fan bracket.

[rakkasan]

$700 for one that's been P&P'd? That's pretty steep when comparing them to Ron's (jt2ma71) manifolds, which are superior in design. One was sold on Ebay a few days ago for $545.

Yes that is expensive but and my custom one off ones will be about the same price, (building my own right now to figure out pricing). It is just a huge amount of work to do the PnP. If you think $150 is to much for the 6 to 8 hrs it takes to PnP not to mention the tools and material required. Go find a place that will PnP your stock manifold including cutting it open and doing the inner plenum plus runners for under $250. The $700 includes the standard conversation, Port and Polish, polished outside, alternator drop down bracket, and throttle linkage bracket not just conversation plus PnP. If someone is going to go all out with one of these it is going to be about the same price for a one off one that is PnPed, polished outside, but the alternator drop down no longer works because of how low it is, A/C has to go plus you will have to figure out what to do with the throttle linkage and the ISC will be gone. The idea of the modified stock one is that it is nearly a complete package. With a one off one, you will still be required to do a large amount of custom work to make it work.

im building my own manifold right now (completely new except for stock runners) and i wouldnt sell them for any cheaper than sethron is, its alot of work and material. just wanted to say good luck, your product looks very good, and having flow numbers to prove it wont be harmful is a great thing!

Sounds great. I started my own personal one off one end of last week should be done end of this week. I will then be able to flow it and get a direct comparision in flow performance. Thanks for the kind words keep up the good work.

BTW already have one ordered so still a discount for the next person who orders. I will have pics of the latest one up mid week. Thanks guys!

[Chris-Supra]

I'm the one who ordered and can't wait to get it- So far Seth has been a good guy to deal with.

Hi Chris
Thank you for the kind words. It will done tomorrow and I will have pictures up. Since it is still one of the earlier ones and I was trying some new stuff, you will see that it is most of the way to being polished and has a slight amount of port work. I will show you what I mean tomorrow when I finish it. Let me know if you have any questions.

Price edits sorry did not even realize the screw up, bracketry is much cheaper.

[bigaaron]

Since when does someone else's product determine the price of his manofold? I think it is a cool ideal and looks nice when polished. If it is too expensive for you, don't buy it. I can tell how many hours of work went into it and I think the price is reasonable.

[supra_stephe]

so why didn't you increase the plenum volume? It would increase power/ torque, as would ram pipes? Since you cannot clear coat the aluminum to prevent an imidiate skin and corrosin and oxidation? Do you have any problems with this?

[sethron71]

Not neccesarly. Increasing the plenum size will not really make more power and torque. If the manifold itself is a choke point in the system then yes increasing the size would take car of that but you are feeding it with at most a 3" pipe. Also the size is slightly increased by the added stub. But if you just say make the plenum as big as will fit then you are just causing more lag as that is more volume to fill with the boost. Yes on very high horsepower apps running say 28 plus psi area a larger plenum would be beneficial. As for the corrosion and oxidation mine it takes 2 minutes to whipe it off, I have used never dull on it once since I did it quite a few months back. Hope this answers your questions. Thank you for your comments and interest.

Sincerely,
Seth Ingham

[supra_stephe]

yeah that coves it, the volume question we can talk (as we already have ) more about on aim. and yeah i was more conserned with the corrosion

[Enraged]

look into zoop seal. polish the mani, apply zoop seal, it wont corrode. easwoodco.com sells it.

[Chris-Supra]

Got mine yesterday- Nice piece- Couple things about it in my experience with it so far-

Mounting the throttle linkage = easy, drill and tap 1 hole where the tb used to be and I managed to get it to mount there, with some dremeling of the linkage of course. I am eliminating the ISC so I dont have to worry about that. If you want to keep the ISC, you need to expand the push rod about 2 inches, no big deal. I did this myself, I did not pay him to make it for me, saved myself an easy $75 or whatever it is.

Vaccuum port by the TB was glued in- and wasn't glued in very well. Not a big deal, getting jb-welded in at this moment.

Hood needed to be banged a little to get it to close with the tb in the more forward position.

The alt. tentioner should have been longer, its too short to be of use. Unless I did something wrong? Seth? Stock one works fine- or you could get a shorter belt too.

The lowering bracket for the alt. is now the SHINIEST piece in my engine bay. Bling*

All in all, for $345, I feel it was a worthwhile investment. It isn't the most perfected piece, but I'm sure it will do nicely for my needs. Remember too, Mine is his first sold to the public so I'm sure he will take my issues into consideration and improve on it for the future.

Do I reccomend you buy one from Seth? If his product fits your needs for a manifold: Lower cost- effective, and your not looking for engine bay bling then yeah go for it. Seth is a good guy to deal with, and he will get you what you want/need.

I like this -- kinda stock looking. It's the kinda thing that would make me look at someone's ride twice at a Supra meet -- I'd do a double-take. :)


Interesting information! Some numbers work nets this...

Flows 7% better than stock
Flows more regular across all cylinders - stock deviates by 4.8%, modified deviates by 3.6%.

Sounds like quite the enviable mod to me.

Were these numbers taken from this specific FFIM, or a different one? The flow regularity across cylinders was the big reason I was wondering about getting one -- "conventional wisdom" on the boards holds that the stock IM will deviate less than an FFIM.

[Satan]

I just emailed him to see about getting one also.... I have a BIG-@$$ intercooler and want to keep the piping the same as with the 2JZ I'm pulling out, and use it with the 7M I'm dropping in.

Can you post some pics of what you have and the changes/mods you made as noted above? Thanx!!

[Inygknok]

how bout you look for a way to keep the A/C? its the only thing troubling me :icon_conf

[sethron71]

A/C is easily kept with just the alternator drop down bracket.

He made a stock TB adapter plate in conjunction with the Q45 TB bracket so I when I can afford to upgrade later:naughty: LOL....and alot of other little nit-picky add ons....

Its in shipping right now, I orderd it unpolished but he scribed his name on it somewhere for me...since why would I buy such a nice piece without a name on it??? Heheheh.

I told you guys I dont play around....wait till you see the whole set up!

[siman]

Hey seth! I just finished the first polishing today!

I will post some pics tonight! Also I will put it on my friends motor at his house and take some pics of it mounted! I looks SOOO GOOD!

-Jonathan

[Reign_Maker]

Cant wait to see it Jon...

[siman]

Damn, I forgot to post pics LOL... I polished up my stash of parts yesterday. Only the first polishing in 3 steps I do believe.

I have in the pics Sethrons71's manifold, Ron R.'s alternator relocation bracket, polished fuel rail and in the little zip lock baggy my Stainless steel braided Lokar 36" Hi-Tech throttle cable:

[audioman81]

any pics of the alternator bracket on? closeups of everything would be awesome.
thanks,
