hey guys. got my typhoon intake and i have a couple issues here. One, it doesn't have a hook up for the EGR. do i need the EGR?? i'm already going to have to get another throttle body for it b/c the stock throttle body won't fit up to this intake manifold. so can i get a mustang intake or something and put it on here and eliminate the EGR without any issues?? Also what TB would y'all recommend???

the other issue is it says it eliminates the factory vacuum tree. it says to hook up this vacuum line they send with it and a tee fitting and run 2 vacuum lines. one line for the fuel pressure regulator and the other to the map sensor. what do the other 4? vacuum lines go to and do i need to find a way to hook them all up?? all my labeling on the lines came of due to some rain getting on them so i can't tell off hand what they go to.

i have a smog eliminator, but being new to these engines i'm not sure what this is going to do either. is this going to delete flow to the EGR or what? thanks for any help guys. i will get this truck running one of these days.. haha

 

Conaski runs a Typhoon & should be along sometime.

Got a buddy with a 5.0 mustang to compare the set up to?

As far as the EGR goes, out of 12 guys who run without it, 6 have no problem. The other half a dozen don't ever seem to get theirs to run right.

Charles E Probst who wrote a book called " How to Understand, Service & Modify Ford Fuel Injection & Electronic Engine Control" (See a pic in my gallery) says that the EGR stratagies built into the EEC-IV vary greatly between vehicles in how the air/fuel mix reacts to the lack of dilution when you remove an EGR system. Some go lean, some go rich.

I think that would explain the many different results reported here, that happen when the EGR is deleted.

Just my 2Cs'. Post up some pics of your install.

 

while i do have pics of the engine. i don't have pics of it with the manifold b/c i wanna know how to get it to work before i throw it on. the engine is out of the truck. i still have to figure out how i'm going to wire it in my '94 that used to have a 300 I6 in it. i have the '92 harness that this engine came from, but i'm still not sure if i need to use it or get a different one.

 

The Typhoon uses internal EGR like most car intakes so you need a mustang style EGR spacer and valve. I plan to use a 70mm version with mine since this is the size of the TB opening in the Typhoon upper, a stock mustang TB will be way too small. A stock mustang EGR valve will work though.

 

dang. and i was hoping to be able to get rid of that ugly junk.. so i need a stang EGR spacer and a 70mm stang TB right? i hope i can remember how all this hooked up. haha. i will get those parts ordered..

Conanski, what about the vacuum lines????????

 

How are you guys planning to rig the throttle cables up.

Does the Typhoon Lower Intake have the large (1.5" diameter) hole at the rear of the manifold on the topside? What goes there?

 

Mandatory manifold vacuum lines for EEC-IV engines:
- one small for the MAP sensor
- one small for the fuel pressure regulator
- one small for the emissions solenoids.
- one big for the vacuum booster
- one big for the PCV

Depending on particular vehicle you may have one big line going from the manifold tree to a vacuum tree on the firewall, where it splits into several other vacuum lines for cruise control and HVAC, and sometimes the brake booster lines is hooked up there as well.

In case of limited number of vacuum ports on the intake manifold, I'd recommend that a firewall-mounted vacuum tree is used instead, '83-'94 IDI-powered diesel trucks have that for sure as we do not have any manifold vacuum and we run vacuum pumps instead to power our brakes, HVAC, and cruise - install the vacuum tree where you find a suitable location, run a 3/8" vacuum line between the intake and the tree, and then hook up all your factory vacuum lines to the tree. Be aware however that it's recommended that the MAP sensor gets its own dedicated vacuum line from the manifold, as its vacuum signal needs to not be "contaminated" by other vacuum-using devices such as the brake booster. Aditionally, the PCV should get its own manifold vacuum too, as if you run it to the firewall-mounted tree it will oil up inside and eventually plug up - if you cannot run a dedicated PCV line, then install a breather, but do not hook up the PCV to the vacuum tree.

About the EGR - the Mustang setup will use the same vacuum line (usually green in color) that you have running between the EVR and your factory EGR valve, if said vacuum line ain't long enough feel free to extend it using small-diameter vacuum hose so it reaches the EGR valve in its new location. Depending on which way you are facing the throttle body you can hide the EGR valve from plain view, in the factory Mustang setup the throttle body is on the passenger side and the EGR valve sits towards the firewall so it is not really out there in your face to bug you

 

ok there are not enough ports in the typhoon intake to give the MAP, PCV, and brake booster their own vacuum lines. or at least they didn't give me enough fittings for to do that b/c they are saying to use one line then install a tee fitting and run that to the MAP and fuel pressure regulator. Conanski, i would like to know how you hooked up all your vacuum lines.

thanks guys for all the help so far. i will get an EGR spacer and TB this next week so i will be one step closer to done with this thing. i can't wait to get the engine dropped in this thing and started. this may just be my last EFI engine build after all this trouble i'm having and can't figure out how to get it all working. i did a lot research and figured out these parts could all be used on this truck, but i didn't know they were going to cause problems like this with the vacuum lines and stuff. again. thanks guys!!!

 

A vacuum tree is the answer, go to a scrapyard and pull one off another vehicle.

 

i figured out that the stock vacuum tree fits in the rear port of the upper intake. so i can just put the stock tree in there again. i shoulda checked that to start with. haha.

for the ccv are you allowing the ccv to go back up into the intake like the original or are you putting a breather on it???

 

Ahh. OK. I'm thinking there isn't enough clearance between the intake and firewall for that to work but who knows. I still think a firewall mounted vacuum tree off one of the cars is a better solution.

ccv? Do you mean PCV? That's the big hole in the lower intake right at the back, this can be plumbed into one of the ports in the upper intake.

 

Count the ports on the car vacuum tree tho, some have only a few, which may not be quite enough for your application. Compare to a tree from a diesel truck, and use the one with more ports. Agreed, but if you cannot run the PCV hose directly into the upper intake do not run it to the vacuum tree instead.

 

i guess i'm going to have to find the PCV valve and check it all out to see where i'm going to have to run everything. Conanski, did you run your typhoon with a vacuum tree like this??

 

I haven't finished building that motor yet, but I do plan on using a vacuum tree with it to keep things cleaner.

 

right on. i will try to find one of these vacuum trees. you think the one off the diesel would do what i'm needing?? or should i get one from a gasser? if a gasser what should i look to get it off of?
