Is it possible to hit 13,s with my mods?

slayerripkdc · Aug 18, 2004

Hey guys i was just wondering if it is possible to break into the 13 second range with my mods and sticky toyo street tires????

Borla exaust
mac off road h pipe
bbk long tube headers
moroso cold air
73 mm mass air
65 mm tb
24 lb injectors
373 gears

I also have toyo proxies and they hook very well, i can lauch upward to 2500rpm and get full traction and it is a standard.

I am asking because my freind said he had an lx 5.0 and when it only had 355,s and a cat back and he swears he ran a 13.8 at i belive 104. so is it possible to get close to stock mustangs in the 13/s with good street tires

Hmm...your friends time seems a bit fishy...not neccesarily the E.T. but the mph (104)...is awfully high for just for 355's and catback...unless his car was stripped of ALOT of weight...and he had a good tire...

Well I wouldn't expect to get a 13 but it is possible...those 24lb injectors you have are probably to big for the car...but it shouldn't hurt you really...I would think if you can drive your within reach of a low 14...

I agree about the injectors. You are gaining no performance from them with your combination.

Your friend could have ran those times...but as was stated before...not with those trap speeds. With his level of mods, chances are he is trapping no more than 100mph (and that is on the high side).

As far as your car though, it is capable of running 13's with a good driver and some traction. How deep into the 13's though is really up to the vehicle condition, drivers skills, weather, elevation etc. Mid 13's are well within reach in ideal conditions and some nice hooking tires.

So what no gain in performance, they are only 5lb+ over stock and as long as you have the correct MAF, YOU ARE FINE. They are there for when you grow into them.

Your friends times either are lies or he had more mods.

Run ET Streets and use a short belt. You will hit a 13.

He listed the 24's lb's as mods and millhouse and I were simply informing it isn't going to help...and unless your not familiar with the EEC and MAF...5lbs to much can hurt...but in this case he is apparantly fine...

19 vs. 24 is roughly a 20% increase...unlike comparing to numbers like 95 vs. 100...

Yeah a short belt is what you run on the street

NotoriousGT350 · Aug 18, 2004

It's possible. The best I have is in my sig with just exhaust and 3.73s on street tires. Elevation with air here made it to 4000ft + above sea level that night. Corrected my time should be high 13 at sea level. Now if I had some tire, times would definately go down.

N8Miller · Aug 18, 2004

play nice fellas.

13 possible-yep. the injectors are fine as long as he has an AFPR. If hes got those 24s jetted high, then its gonna downplay his setup. If he has them backed off a bit, then no big deal.

as for your friend..... ever herd of a 75 shot??

Mod right now, no, later yes. People including ME have run 42lbers with the correct MAF on a basic 351w before and it ran fine enough to be on the street and it got up and went. 5lbs can HURT, without proper compensation ex. correct MAF.

But you are wrong, those injectors are NOT to big for his car. Millhouses statement of NO performance increase was right, but they are in NO WAY to big for his car.

What's wrong with running a short belt on the street? You aren't strong enough to turn a non p/s wheel? If that's the case for the thread starter, change it at the track then. I dropped .5 off my ET from just the short belt with the same 60' no other mods.

Me not strong enough... ...learn before you speak...

Short belt is cheap...

I said probably to big...inferring that it isn't going to help...did you not see Millhouse agreeing...he got it...why didn't you?

What does it matter if the mods are on their now or later...you just trying to find something your right on...

If your a good driver...13's will be there for ya...

agreed, the time is common.
that mph is very high. you can break 12s with 104mph, and a kick ass 60'

as for 13s, as long as you can trap 98-101 or so, and get a decent enough 60', you should be in easy.

Short belt is cheap? So the short belt is not good enough for the you. I see now, you're above the short belt. Well I wasn't telling you to run the short belt now was I? He just wan'ts in the 13's, that's a way to get there.

Probably to big...? So that tells me you are not even sure. Shouldn't you be positive about it before you open your mouth?

It matter's because you make this guy feel like he did something wrong getting the 24lbers, which he wasn't.

I bet you're the kind of e-guy that likes to comment on people's TB's being to big for their combo.

You can have a TB thats too big...MMFF has done dyno testing to prove it. Drop a 75mm on a stock 5.0 (even if you open the intake opening up to accept it) and you will run lean and have drivability problems. The point about the injectors is simply that if they are too big (IE non AFPR) then the computer tries to shorten the pulse/cycle to adjust the A/F ratio and he will not get a consistent results/drivability. READ FORDS service manual on their EFI system. It will explain it.

24's are not the incorrect size as long as he has a AFPR to keep his Fp low enough to allow the puter to do its job. He will grow into the 24's, it's good that he is planning a head and not wasting money replacing the same part 2 or 3 times. Run your car rich and see if it effects your performance.

Think of it this way...does your car pull harder in hot weather or cold? Cold air has more oxygen and thus you can dump more fuel into it. More fuel and air equals more power. ( elevation effects power the same way)

just my 2 cents.

millhouse · Aug 18, 2004

I personally dont agree with the 24lb injectors.

Will it hurt...probably not (although it is possible...it's only detrimental to his performance though).

As far as future upgrades go, they are not going to do much. The common h/c/i setup can reach past 300rwhp. Although stock injectors are commonly capable of handling these h/p levels, it's about the limit. After 300 h/p though, whats next? Most people make the jump from 300h/p to 400+ via nitrous or f/i. At those levels, 24lb injectors are useless.

Again, it's just one of the mods that wont be utilized until some major bolt on's start happening. The money is better spent elsewhere.

slayerripkdc · Aug 18, 2004

thanx guys for all your responses hehe yea when i ordered the 24 lb injectors i also ordered the correct mass air metter as well. I actually did these mods in favor of a little supercharger..... i am planning on goin with the little baseline vortech blower i belive it is a 5-6 lb blower so i feel my mods will support it very well. Then from there i will change the upper and lower plenum as well. I also have a have a smog pump delet and i run a belt minus the smog pump, it prolly doesnt do much for power. I also run my abby at 14 degress timing

Js5ohLX · Aug 18, 2004

We see way too much of this 24# too big crap. What did they put on the 93 cobra?? Ah yes 24's, does it need them, no. Does it hurt, NOT AT ALL. It is considered a mod because it is not stock. Is it a performance mod, right now, no, but it is a mod and it won't hurt. Look up 25thmustang, he runs stock heads 373's and a cobra intake and hits 12.67. Sure he's gotta shift like John Force, but that's fast for pretty much stock stuff. Have tmoss port your intake, and you'll fly.

you are right but the guy isn't necessarily lying like OTHERS have "said". a buddy of mine has a 98 cobra and the best he ever got was 13.8 @ 104. we both knew the car could easily run in the 12s and he's knows how to drive so that not the reason why he never hit them. the reason why he never hit the 12s was 1. he only raced the car with street tires 2. took off slow from the line in order not to keep slipping on the line.

on the other hand another buddy of mine has a 92 convertible and only managed to hit 13.8 with slicks(never knew his time). he had all the bolt ons so maybe it was him.

13's are def. possible

24lb are useless in your set up.. [good for down the road when moding] 19lbs are good up to 300-350hp.

mustangsquared · Aug 18, 2004

I LOST hp/Trq when my AFPR went bad and I put a new "Stock" one on. Stock is set at 38-42 lbs...thats alot of variation since with my mods I was sitting at 37 lbs with my AFPR for the best performance...churp second gear without breaking 4500 rpms...(not real impressive I know but she is NA). Now I cant churp second if I go to the redline and then some. Are the 24# a "bad" mod...NO...are they hurting him? probably not. Will he grow into them...without a doubt. A good solid tune up (to include proper FP) will help him get to 13's.

Is it possible to hit 13,s with my mods?
