blow-through mod (56k warn update 3/24)

just double checking before i order it.

to my Knowledge these are the only thing i'll need to blow-through. i'll wait a couple days to order, to be perfectly sure.

gm translator
gm 3in maf
dejon 2.25in blow though uip w/tial bov flange (stock intercooler)
dejon 2.75in vpc intake pipe (16g)
k&n 3in air filter
tial bov

my only question is, when i upgrade to a fmic that has 2.5in inlets, will i have fitting issues with this 2.25in blowthrough pipe?

i'm not an expert on this type of mod, but how do you fit a 3" maf on a 2.25" pipe?

the 2.25in is the taper to the inlet on the stock side mount intercooler.

Yes, that's all you will need. I sort of question the benefits of a MAFt this early, but you seem headed on the right track, especially with that tial BOV instead of the ricer ones. :)

I'll be waiting until I get a FMIC to do this, but I guess if you use a FMIC piping that is 'long route' as in goes through stock SMIC location to your UICP, it will still work. If you are planning on getting 2.5 inch FMIC piping, you might consider 2.5 inch UICP right now, so it's consistent later.

You can get silicone (and probably rubber) reducers from 2.5 to 2.25 so I wouldn't worry about that, but still consider getting 2.5 inch now if Dejon sells it. (havent checked)

they do. same price. i'll get that 2.5 blow through pipe insted and find a reducer to match with the smaller inlet on my smic. good idea, no bottleneck in flow when i upgrade to fmic

long route dosent effect performance? does it?

Not really, on a small turbo like stock it may affect performance, because it's such a small turbo and a long way to go. You might see some pressure drop, but you would see that even with short route piping. When you have an upgraded turbo I doubt there's much of a difference at all.

EDIT>> And you'll be so happy when you get a FMIC that it won't even be an issue. :)

i'm looking at the MAFt more and more...

The only way I WON'T get one, is if I stumble upon some money/great deals and I just go ahead with DSMlink.

ok, could i fit an MAFt in between my TB elbow and the GReddy UICP's? i know i would have to cut something in there, most likely the TB elbow. would this be too close to the TB or does the proximity matter?

also how do you tune it? like a laptop or Palm???

well, i just bought the eprom ecu, i plan on running maft & dsmlink

I'm not aware of any effects of having the MAF closer to the TB, but it seems like everyone keeps theirs halfway between the BOV and TB elbow, in the straight section. You will probably want to cut a section out of the UICP, put in the MAF and 2 reducers.

You tune with knobs on the MAFt, and watch results on a datalogger which is seperate... whether it's pocketlogger on a palm or DSMlink on a laptop.

This is the pipe I just made for a 3.5" MAF. Nice gradual transitions. Couplers are THICK, from www.sporthoses.com. Tial BOV will go right before the coupler to the MAF, or in the LICP. Most likely LICP just to keep things clean. Not sure what the effects of having the BOV before FMIC will be, but there is only one way to find out. I aint scared! :grinno:

You cna also see what the term "short route piping" really means. This is all that lies between the FMIC outlet and the NT TB (thats what the 3" elbow connects to, the NT TB. No hard TB elbow. saweet)

Maybe this will give you some ideas at least for when you get your FMIC. I would sell the dejon pipe (should be easy, everyone is doing the MAFt thing), and just use couplers for the MAF on the UCIP they give you in the kit. Really straight forward.

yeah, where did you get the 2 pipes from?

the longer your ic pipes are the harder your turbo will have to work to create more pressure right? probably not noticable but might as well do it right the first time. shortest distance between 2 points is straight line so shorter is better. also joe why wouldnt you get a MAFt with dsmlink? does dsmlink have features that would work like or better than the MAFt?

MAFt and DSMlink are really two seperate products with two seperate roles. I use both together. MAFt just to use the better MAF, and DSMlink to tune, and everything else it does.

Updated the page with more pics. I'll get some better "finished" pics up later. Kinda sloppy here but you get the idea.

i read in a sport compact car mag a while ago that the bov should be placed close to the throttle body becuase thats where the most pressure is at. dont know if it really matters tho.

The pressure spike, and reverse pressure wave, will originate at the TB. But the source of the rising pressure is still the turbo. I dont think it matters much. One advantage to having it closer to the TB though is you keep the momentum of the air moving towards the motor, not backflowing away from it. We'll see how much of an effect this has, my tial is before my FMIC :D Just no room on that uicp with the 4" intake pipe in place. .

damn 4 inch intake pipe. take a pic for me under the hood. so you really cant tell a difference wehre the bov is at? does it matter if the MAFt is before or after the bov?

The MAFt has to be after the BOV, since I have to run it vented. There is a pic on my page on my site. In the mod list, click on the 3.5" MAFt item, and there is also a link to it in the tech pages. I need to get a "finished" pic, but those give you an idea of what it looks like. I dont yet know how it works witht he BOV in the LICP, still waiting for it to get welded tomorrow.

i just need to ask, do MAFT have diffrent wire harneses for 1g & 2g, that you need to specify when ordering? or are they all plug and play?

The software is also specific to the generation, since they have different MAS curves. So be sure to order the right one.

damn... your motor looks brand new except for the valve cover... everything is all shiny... exspecially the tranny!!! looks nice man, hopefully i will be doing that shortly!

Funny you mention that, I have a polished valve cover I'm going to install today. I've had it for some time. My brother took it to work a year ago and has been working on it when he doesnt have much to do. Found after though it had some cracks, so I took it off to JB weld it from the inside. After 2 months, I think its dry :D

Ok... Kevin, did you ever mount the BOV on the LICP?

On thursday I finished the blow thru setup and MAF + T install... Now I need to move my BOV on the other side of the MAF. I thought about putting it on the J-Pipe but I am not sure yet... Any ideas? Here are some pictures of the install. (Thanks to Kevin for the pics of his setup, I had to be a copy cat) :icon16:

Thinking about putting it on the J-Pipe under the upper radiator hose... Just cause its out of range of water and other shit. Throw out some ideas. Thanks guys.

shouldn't the BOV be after the MAFt?

No... Before, like BOV - MAF - Throttle body. The way it is right now is wrong.

ya i meant before not after :p

damn, the more i learn the stupider my older posts look. oh well. nice setup!

yea seriously what a dumbass i was... but hey eclipse rst do you want to sell your old upper ic pipe elbo that comes off smic? im in need of one quick. let me kno asap cuz im about to order a dave brode pipe tomorrow (Sunday)

No can do... I hacked it up to shit as you can see in the picture. The pipe that the BOV is mounted on is my old UICP from the SMIC. My plan is to hack off the BOV flange and just toss the pipe in the trash then weld the flange to the j-pipe! ;)

Nice UICP!! Rock out with your cock out...

I did mount my Tial on the LICP, and I'll tell you, it takes forever to open after I let off. It just takes too long to build up enough pressure under the valve to pop it open. It also doesnt help that I have the highest spring rate (11 pounds) and only ~6-7 pounds of vacuum (in/hg divided by 2). With the 7 or 9 pound spring the vacuum alone should be enough to open it. I may try to move it back to the UICP somehow. It will take some creative relocation to get some room in that area, maybe even a slight rework of that UICP. If there is any way you can fit the BOV on that transition right before the maf I would give it a shot. I dont like having the BOV so damn close to the MAF, but what can you do on such a short UICP. Actually with your setup, depending on how quickly the pipe bends in, there may be room right after the IC outlet.

i just need the elbo that comes off the smic . i can make the rest my self.

jake did you press bend those intercooler pipes? they looked a little crushed.. wont that hurt the flow a bit?

lol thats my "Ghetto rigged" LICP for now... I have a mandrel bent 2.5" pipe coming this week, I just wanted to fit everything and make sure everything works good. I was going to dyno it this last week and I wanted the FMIC on and hooked up for that but it didnt happen. Anyways, the whole setup will be different by next weekend. I got a different FMIC coming (the right one... 24x12x3" core, the stupid vendor sent the wrong one so they sent out another one, that will be here tuesday) and then the LICP should be here tuesday as well. Then I'll probably move the BOV onto the J-pipe but who knows. We'll see how it goes. I'll keep ya posted.

so you want to sell me that elbow when you get a new lower pipe?

the stock maf cannot be pressurized.

I knew there had to be a simple reason; thanks dsmodder. I assumed people went with the GM maf simply for its larger flow properties.

If you are interested in why they cant be pressurized, google Karmen Vortex or vortices. It will explain the concept behind how our stock MASs meter air. Its quite simple once you know why. And I'm sure I've posted it before. Just mentioning it because it is a somewhat interesting topic, worth 10 minutes on google to learn a bit about, for anyone with a DSM really.

Well after fucking around with it for a while I ended up putting the BOV on the J-pipe. Turned out good and opens just fine, the vacuum line is actually shorter to where it's at now then when I had it in the stock location before.

Ended up buying Vince's (Boostedspyder) Type RS BOV... Sounds great, looks good, gotta love it!

Then I decided to pull off the case cover and take a look around for the oil leak I have. Well come to say the least, the oil pump got CW and fucked up the whole cover... So after diggin around in the mud I pulled up this one.

Amazing what 15mins and a parts cleaner can do isnt it? Had to get a shot of the crank and under part of the motor...

While I was in the area, I changed out the timing belt components and put on a new kevlar timing belt just for added security. (I've been known to snap a couple T-belts in my day). Then I got bored and decided to redecorate my valve cover. Cool paint from Dupli-color.

The company I got my FMIC from sent me the wrong one and finally they sent me the right one after all so I put that on and it looks a lot better now!

Then the last 2 days I have been on the way to ohio and back to look at a car for 96spyderman... So thats been my week... Talk about hectic! Guys like it?

Oh... And about 2hrs ago, went out and did a couple runs down the main street in my town, blew my water pump... So out comes the motor tomorrow! Fucking shit. I got class tomorrow too and I pick up 97_3clipse's car on friday... Damn I'm getting too old for this shit!

Well considering there is chunks of my water pump under my power steering fluid container and water was spraying everywhere from there... Just a hunch that its the water pump! :p

Damn jake!!! Looks pretty sweeet... If ya don't have my 6bolt all put together yet... um... could'ya do some cool paintin on my valve cover tooo?... he he he... Gimme a call... really soooooon!!!!!
Car definately looks better with the FMIC from when I saw it a few weeks ago!!
