94 mustang gt CARBURATED!!!

so i've had my 94 mustang gt for about 2 months now and it runs strong and fast... the fuel pump went out so i just decided to convert it to a 650 edelbrock performance series carb!!! i'm running the carb almost to its max at 7 psi, theres no problems with it... i was just wanting some input on what everyone thinks about that? i'm getting aroung 12 mpg highway and 8 in town... the deal is it's running super fast, as in i raced a buddy of mines cobra that ran a 13.8 and beat him by 2 lengths!!! the second deal on my car is i'm running a cobra block!!! the question i have is can a carburator really make me that fast??? or would just the cobra block i'm running make me that fast?? so another question, would you guys/girls say i'm that fast cuz of my block or carb? or both? oh reference: i have a 3:55 trans

... I think you have a few things twisted around here...

I'm guessing that since you say you just got the car 2 months ago that you didn't do these upgrades listed in your signature.

Whoever told you that you have a "3.55 trans" is full of shit.
-You probably have the T5 trans, but the 3.55 is your rear end gear.

Also unless you have a spool in your rearend then you have a LSD (limited slip differential). This is not "posi" but both rear tires will spin if the diff is good.

Now, to answer your question... how do you know you have a cobra "block"? Is it just a bare block out of a cobra thats been rebuilt? Is is a cobra short block (block & rotating assembly)? A cobra long block maybe (heads to oil pan)?
If its just the block then thats not doing anything at all to make you "fast". The carb may help some, but not enough to make a stock heavy SN95 car run 13's.

You went carb huh? :evillol: 351stang is absolutley correct, the block has nothing to do with the power your making . Power is made in the induction and heads. The reason your making so much more power is because you have taken the shackles off of your car. By shackles I am referring to the T4M0 computer. The stock computer has horrible programming from the factory. It pulls timming while shifting or during hard acceleration. Also doesn't take to engine mods well at all. By putting a carb on and taking the computer out of the picture you automatically pick up hp. Not to mention the crappy stock intake. Quite an advantage over the same car similar modded with a T4MO or J4JL (cobra computer). Thats the good news, the bad news is now your a lot less efficient. So your gas mileage just took a dump. If you don't mind the gas, I say go for it. Just keep the carb tuned and you should be fine. I ditched my T4M0 for the A9L.

thanx for the info, everytime someone asks me why my car is so damn fast for being just a basic mustang gt (with cobra block) i really don't know how to answer other than well its carburated and has a few mods here and there!!! so my new answer would be no computer to hold me back? ya gas is really kicking my ass at 10 mpg highway and like 6 in town!!! it costs 33 bucks to fill from empty but i'm only getting 160 miles out of a tank if i'm lucky!!! but she's just my toy!!! thats why i have a probe GT (just for the milage!!!!) well thanks alot!!!

so is there 306 heads that are performance made for my car? if i could do all the work myself and they do make 306 heads do think i could do it for under $1200? i'm only 17 and i worked hard to get me something worth working on and i wanna make it a 11 seconder!!! or faster... would like some info on any performance no matter cost cuz sooner or later i'll do it... my next transmission project with be like a 4.10 or 4.11 which ever it is... not to knowledgeable about this stuff but i've got a knack for taking stuff apart and putting it back together... taking all tips and critizm! thanx

Theres no such thing as 306 heads, the heads are on the motor, but 306 is the cubic inch (size of motor).
Just like the 3.55 deal, 4.10/4.11 are not trannies. They are rear end gears. Not transmission gears.

Dude, your mods do NOT = a 12 sec car, that would make you run with bolt on NE 4v's and stock Terminators....and your not.

You have a 14sec car with intake, carb, exhaust and gears...either your car has mods your not listing/don't know about or your friends a REALLY inconsistent driver to run 12.8 then lose to you.

my friends 5.0 has a lot more then yours, and and weighs a lot less, and a drag suspension and runs 12.4 off the bottle. So I KNOW your not doing those times, with the mods you have listed.

i never said 12's i said he ran a 13.8... that was a slip time so that time was on a strip! which means i guarantee he grips hell of a lot harder at a strip than a street race...???

There are ways to keep your power and raise the mph on this car. One is a chip which will regulate the mixtures better unless this also was striped out.

I wouldnt recommend 4;10s unless you are only doing 1/4 mile races, past that youll get smoked. I have 4:10s in my mustang and i am not getting enough top end.

A chip will control timing and A/f ratios on injected cars. A chip aint gonna do shit for this car. A chip cannot "regulate" any mixtures at all, because it has a carb!

As I have said many times before, the whole deal with 3.73's for the street and 4.10 for the track is absolute BS unless your car is just stock. The best gear for you will depend on your max rpm, rear tire height, and top speed. Also the converter can have a lot to do with it.

well i am topping out at 154 in 5th... i can get there in less than a half mile... does that help any??? ya i know chips are out of question cuz i have no computer what so ever... and yes i do just want this car to be a stip car... and i tack each gear out at a weird rpm... it doesn't even redline, it gets to about 5,700 rpm's then jumps to 7 tacking out...!!! and when i say jump it just drops to 7 faster than hell... just some info... thanx

What tach do you have in the car? Also what speedo?

Also a stock T5 wont allow the shift at high rpms. Most stock T5 racers you talk to have to let the rpms drop to shift.

My car has a t5, and my buddy that owned the car before me shifted at 7,000 rpm with no problem, me i shift at 6,000 to 6,500.

I know when I drove a stock T5 that wouldn't shift past around 6k I asked about it. Several people said they have the same problem. Now, if I shifted it slow it would work (letting rpms drop just a bit), but if I tried to power-shift it wouldn't, also if I just shifted too quick using the clutch it wouldn't.

i just have the stock 150 speedo and and stock redline at 6,000 tach... i try shifting at 5,600 when i race... think pully's would let me go further with my rpm's???

I'm just wondering if you're speedo stop at 150mph and your tach stops at 6K. . . How do you know you were going 154mph at 7K in a "stock" SN95.

<-4.10 and SCT on a Mach1...i have never lost to any m3 at the track or on the street

Who ever maybe a 4.10 isnt to hot for GT's, but on my car...its a GREAT gear for HW rolls and the track. I get to 130(top of 4th) pretty quick.


And I misread your post I thought you said 12.8. Either way...you have a car thats NOT going to beat you friend unless he cant launch. Ive paced 96-98 GT's with more mods then you in my escort. For his cobra to be doing 13.8 he better have a stock 96-98 4.6, or a modded 94-95 5.0

no, my speedo doesn't work but i had my friend drive by me in my TSI and we hit 154, i think my tach goes to 8 or something.. not quite sure... what's some good websites for 94 5.0 mustang performance parts???

hope your not pushing that 5.0 to 8k.......

Its got stock heads & cam. It's not gonna make any power at those rpms. It will drop off before 6k.

car wont even allow me to go that high... shift at 5,700
