ive searched and didnt find a good answer soo. what in everyones opinion and fact is the optimal set up for a n/a motor. maf, tb, injectors, timing for a "stock" intake and heads? its a 306 intake upper and lower ported out, heads ported and smoothed. i have heard a 75mm tb and 80mm maf with 24# injectors is the best to go. im looking for performance, not gas milage. any thoughts, ideas or opinions would be appreciated. thanks

you wont need a maf or tb that big

[lone5oh]

ok, i have a guru(friend) who is gonna come look at my car, i had a stang while back lil bolt ons and thought was fast. i just got another that was brought to me from west coast, was supposed to be street/strip, heavy on the street. im thinking not, this is what ive been told and figured out. 80mm maf, 60mm tb, 19# injectors, ok now for the fun, k&n filter, ported heads and intake, msd ignition, 9mm ford wires, x303 cam, 4.56 gears, auburn limited slip, x pipe, mac long tube headers, mac mufflers, no cats, tci aod, with stage 3 shift kit. lakewood shocks in front, eibach lowering springs all around, caster camber plates, 275/60/15 weld racing rims, cowl hood, ignition timing was bout 15 degrees moved it back to bout 12, if you let it shift on own it shifts at 3500 and will come sideways even in 3rd if you are really on it. so im thinking more heavy on the strip, its fun in the grrrrrrrrr sense, but not too sure bout the fun driver sense. obiously i need bigger injectors, bigger tb and diff intake. im working on that. havent taken her to strip but it lopes reall nice. no check engine light so im thinking is all cam. opinions or thoughts let them fly, im here to learn the easy way or the hard way. also im running 93 with lil bit of cam2. thanks

the sub frame connectors were forgotten supposed to be on the way to me.

Combo sounds horrible..... Will run low 14's .....you will run out of gear way too soon.

[Hunt_chevs]

the gears you mentioned are ridiculous, and you'll max your revs out before reaching a 1/4,.. you dont need that big of a t/b,... maybe consider some control arms

[Hunt_chevs]

take a look at mustank's signature,.. hes running on factory parts breaking 12's

[lone5oh]

so if i read this right change the gears and get a lil bit bigger tb then the small one i have, and things should be back to kosher or am i missing the big picture?? i appreciate all the help you all are giving me, trust me on this. i dont want to go backwards and get a smaller maf or ?? i want to move forward. also the control arms are in the wings actually getting the bars that move the lowers up.

what lift is the n41 cam mustank??

[lone5oh]

got another question, why would my timing be jumping around, when i put timing light on it it moves around?? thoughts thanks for the help again all.

im working on the crazy set up.

whats with the obsession to run a bigger throttle body? leave the stock one till you put aftermarket heads or your just gona lose power and kill throttle response, you wont need a maf bigger than 75mm unless ur boosted and movin some real air

Because you did not pull the spout connector out.....

Who ported the heads and intake? Do you have flow numbers? The word "ported" can mean "ported" or it can mean "back yard hack job". If these are stock E7 heads, being ported isn't doing much for you. No need for such a big throttle body or 24lb injectors.

Is this the same engine you are talking about in your first post? What kind of heads and intake and who ported them? Why do you think you "obviously need bigger injectors and throttle body"? That combination is probably not going to perform very well at all.

That cam2 is hurting you more than it is helping you.

[lone5oh]

first off i pulled the spout, it moves all over at 15degrees with it out, and is all over 20 degrees with it in, it just moves around. machine shop did the port job, just opened them up a lil over gasket matching, smoothed the radiuses on the heads, i did the porting on the intake bout same way. im new to mustangs not cars, been building customs, hot rods, muscle and drag cars for over 20 years. so my question is a mustang duhh question not a car duhh question. when i got the car the 80mm maf was on it, and the question bout why i need a bigger tb and injectors is it runs reallllll lean top end like not getting enough fuel, running 44pds of fuel pressure. the 80mm maf and the 60mm tb dont work real well together, the intake is a explorer intake. cobra runs 24# injectors so i was trying to go that way. im not ignorant by any means but very novice with the tweaking of 5.0's just trying to things right with what i have.

not sure how it converts over to 1/4 all we have here is 1/8 and it seems slow to me its going 7.256 at 118mph with overall 1.53-1.58 60 foot times, im sure thats mostly because of the gears, it just dont act right. had someone tell me my puter may be the reason my timing is jumping all over. im used to 50s-60s-70s cars with no injection or computer, and never had the timing jump all over on them so that is my concern.

matt

[fogged306]

The Cobras have different heads (gt-40) that flow much better than the e7's.. even ported, thats why they use the 24's. Do you know if your 80mm MAF is calibrated for 19's?

[lone5oh]

dont know to be honest, i got this car from a kid, who im assuming just pointed to alot of $$ parts in a catalog, obiously these parts do not work together well. so im trying to work with what i got, and go from there. i figured since i had the maf that a small upgrade to a 65 maybe 70 tb would help and 24# injectors also, the gears i know have to go, they are fun but veryyyyy impractical. the main thing that worries me most is the timing jumping around, i can buy diff tb and injectors and gears, but clueless on the timing. like i said someone told me it may be the computer. what you think on that thought???

[lone5oh]

im working with the knowledge i have with old cars, you bore out a stock motor you put a little bigger intake, carb, better fuel pump with more pressure and move the timing, im working on the air, fuel, spark therory, not trying to out do anyone or say i know everything if i did i wouldnt ask, just want to have fun with the car, and short term it is fun but just isnt performing like i want it too. if its not right i would think fix it, if im wrong let me know.
