I was wondering if a underdrive pulley from a 94-98 3.8l v6 work and fit a 84 cougar with a 3.8l CFI injection system? Besides the stock size injector for this motor will any other size work and like it run?
i tried larger injectors (E0SE) on the 3.8,, too much fuel for the engine to handle,,not saying you wont have a different result.
if you work out the Bottom half of the cfi, you could complement some increased air flow (which is the problem). You may gain some horsepower but you still have to get that CFI opened up and port match it to the throttle plates.
pully setup? id dono
I can't say for certain...but just by looking at the 94+ pulleys, it doesn't look like they'll work.
Now, if you really want underdrive pulleys, you can use the entire accessory bracket setup off of a 94+ Mustang 3.8L. Just be prepared to fabricate A/C and P/S hoses.
Larger injectors won't work in theory or in practice, as jcassity confirmed.
so do they even make a underdrive pulley for 3.8L cfi v6 like the one i have? Is there any performance parts i can do on my v6? i am thinking of twin turbo it between janurary and feburary. which is why i was wanting to upgrade to bigger fuel injector to help the turbos. thank guys
yes to quesiton 1
there are things you can do if you search the board,,ive done a lot of work on this motor and know it inside and out. as far as gains,, your skimming from the bottom of the barrel.
I have a great view of the west here in west virginia. Ill be on the look out during jan and feb for the mushroom cloud,,,,:grinno:
No.
Well, if you're going to add turbos...an aftermarket ECM is in order.
I hate to poop in your Cheerios, but there is a reason nobody has built up a CFI 3.8L. The stock ECM doesn't have any aftermarket support, so you can't adjust for larger injectors, timing, A/F ratio, etc. Thus, the need for the standalone ECM. You can port the heads, port the intake, slap on a nice exhaust, turn up the boost...
and blow your headgaskets to kingdom-come.
It is much easier, both in money and time-wise to either build up a 5.0/5.8...or if you have a hard-on for the 3.8 - Use a late model Mustang version.
so where do yu think the stock ecm is located at? how much for a upgraded ecm cost. i know it would be easeir to make a v8 but i plan on beating v8 after fixing up my v6. on a track it runs 12-13 because of the rebuild kit and racing camshaft and stage 2 flywheel.
Your CFI 3.8 runs 12-13 second 1/4 miles?
Im thinking maybe those are 1/8th mile times:cool:
ok,,, where in the hell did you find that cam?
you need to learn your car from inside out and all wiring if you have fallen in love with it that much. Believe me,, im big on the lighter weight V6 engine. User name "spazpuppies" here runs a supercharge v6 in his and is getting ready to install the intended ecm and wiring harness. THats gotta be a quick sucker.
DO this........look into the 4.2L crank/rods/pistons and install that into your v6. They are bolt on parts so it make you a cheap stroker kit.
i need that camshaft partnumber or source. You need to share that info ********NOW************* or a lot of v6 guys will hunt you down:grinno:
the website i got that 3.8L v6 racing camshaft is http://www.moranav6racing.com/. It costed 275 plus shipping. that is where i am get my performance parts.
which cam did you use , whats the lift and duration?
i didnt think there was a performance cam avail for the non roller v6.
is that a 1/4 mile time? thats fast mister.
(http://www.griffshp.com/belchja/forums/robot1.jpg)
yes its the 1/4 mile for now. Till the twin turbos be put on it. here the cam specs are .050" duration, 204 degrees/intake, 214 degrees/exhaust. i have the Morana Performance Camshafts.
Smells like bullshiznit to me.
Ive spent years researching the 3.8L, in every form, and a rebuild kit, a cam and a "stage 2" flywheel will NOT make it run any faster than a 15 second time.
Quit the BS, you come here asking a stupid question, then saying your car runs 12-13's? If your car ran that fast, you wouldnt need our help.
Have fun trying to turbo a CFI car.
are there darwin awards for comments like that:grinno:
And did you call up the seller and chew thier ass for selling you a worn out cam?,,, those lift numbers are less than stock dude:dunce:
ok,, ive been fishing this thread long enough. I do remember one individual who came on like you did a couple years ago and he ended up handing all of our asses to us. He does have a one of a kind and did the unexpected. He also has a supercharger in his 87 3.8L.
Im usually not one to bash but i gotta say it , your talking foolish. I and others have so much tech support to offer and we keep it real. how on earth did you get the expertise to put in a cam (worn out one at that) and still,,,,,,,,to this day,,,,,,, the location of the eec eludes you?
please,, just forget about this thread,,, start over.
If an otherwise stock CFI 3.8 Cougar will do the quarter in 12-13 seconds with nothing but a rebuild, a cam and a flywheel I, personally, will give a beej to a bulldog, and provide video. You'd be lucky to get a 12-second 0-60 time with that car. Hell, even with the twin turbos you're dreaming about, you'd be lucky to hit 12's in the quarter.
I'm not a big fan of noob roasting, but when you light your own fire...
My bicycle runs 10's, son.
Scott, he posted the duration #'s not lift. There is only one cam listed for use with the flat tappet motors.
To run a high 12 or low 13 in the quarter, you're gonna need quite a bit more than a cam and "flywheel".
Do some research, stop lying and feel free to tell us how the car runs at the track when you become old enough to obtain a valid driver's license.
Jeremy, great picture!
Carm, I don't think you'll NEED to shoot that video, however feel free to do so if that's your thing:grinno: :tg: :giggle: :rollin:
"yes its the 1/4 mile for now"
this just blew me away.:rollin: I mean, what more could a man want?
Yeah, jeremy, i had to right click, "save as" on that one!!!
