ok guys i need an honest opinion and need to know how fast my car really is. ok the last time i raced i beat a 1997 camaro rs automtic 3.8 v6 with 20k on it bone stock by about a car length all the way up to 110.
my mods then were
new 305 with 15k on the motor
210 degree cam
moroso blue max wires
bosch plat 4 plugs
accel cap and rotor and super coil
removed ac compressor
advanced timing
700r4 with 124k on it
3.23 gears with 124k on them
3inch exhuast from the stock y pipe
80 series flowmaster
thats all i had doen at the time
now i got the smae mods above and 18k on my 305 cfi
new 3.73 rear end with new posi
and hooker 1 5/8 headers and bigger y pipe 2 1/2 into 3 inch
with only these few mods will i be able to compete with a new gt?
thanxs for any info guys!

 

no

 

yeah, ay 99'+ GT will walk all over you. the crossfire in 83' put out 175hp, and with your mods your somewhere just above 200 now. id guess a mid 15 from your race wuth the 3.8L fbody, and a 99'+ GT is a second or more faster than that

 

Once the stock motor is gone its hard to say how you will do...but IMO you need a 350 or an extremely built 305 to keep up with these newer stangs. It doesnt help that you are still running the cfi intake and most likely stock heads.

I saw my buddies 97 cobra get spanked by a '01 GT auto (botched launch by the cobra). They are strong cars. I give them the respect they deserve.

Yeah those heads are killing you. The CFI isn't the optimum intake but it can be made to work. That car runs off a map sensor you might want to think about a custom chip for it.

 

you don't have a chance in hell

 

Good luck, but I think you will lose!

 

my car beat a rs that runs 15.5 in the quarter
without the headers or bigger y pipe or new 3.73 rear end
u guys r saying those things wont shave a considerable amount of time off my quarter?
thanxs again for the replys!

 

It will help but the motor ain't making enough power. The newer GT's are running 13's stock and CFI can't hang. Sorry I used to CFI too.

 

i thought newer mustang gts ran low 14's?

 

Depends on who you talk to but keep in mind that the best Evan Smith could do with a stock Bullitt was a 13.91 and they're supposed to be quicker than a GT. He also tested a stock LS1 Z and ran a 12.9x the same day! He's also the same guy running low 12's with the '03 Cobra.

 

Best he did with an '01 GT was 13.7x. The Bullit makes 5 hp more than the GT, but it's also a lot heavier.

 

Nic, How much heavier is the Bullitt? The Z and the Bullitt were also tested in 90 degree heat. Not exactly optimal conditions.

 

I want to say the Bullit weighs in around 3600 - 3700 w/average driver whereas the GT's are right around 3500 w/average driver, but I'm not 100% sure on the exact weight of the Bullit. I just know it's heavier.

 

Think of it this way, we have a guy in Ottawa here that took his bone stock 2002 Mustang Gt to a 13.77.

We thought it was BS and saw the slip and then ppl saw him do it again. We think he should call up Ford and let them know he recieved a FREIK GT.

 

well it sounds like im gonna lose but i still gotta try it guys
i live in utah too and at 4000-4500 altitude u will never see a stock gt run a 13.7 probably more like a 14.2-14.5 i think im in the mid 15's before my headers and y pipe and 3.73 gears. thanxs for giving me ur replys tho!!!!

um cfi sucks. next mod needs to be swapping a performer intake and carb on if you wanna hang with that car. your 3.73's are probably hurting you just cuz cfi doesnt breathe upper rpm.

 

They do.

 

i hate to say this but
i raced a 83 camaro that used to have cfi
and he put a performer intake on it from edelbrock and had a 650 edelbrock carb on their and i wasted his *** bad! my cfi has beaten tpi's and regular tbi's so dont underestimate it!
u guys r probably right with the new mustangs
they got 260 hp and i dont know how much tq but it's ok soon im gonna get my car dynoed to see what she has now!
thanxs for all ur replys!
jesse

 

edelbrock doesnt make a 650 *******, and if he did have a 650 on it its over carbed for a 305. i am not saying put on a performer setup and instantly its faster, but if you want any type of upper rpm horsepower you are gonna need to ditch the crossfire.

 

Those are NOT mods. Thats like a tuneup spec sheet! It sounds so funny when people quote "mods" as being plug wires and $8 plugs. Want some real advice? My girlfriends camaro walks away from brand new GT mustangs including a greenish Bullit stang we raced on Speedway Friday.......here's the recipe.

DUMP the EFI. Way too hard to make cheap power on a 305.
Bone stock 305 block, stock heads, RPM intake, 600cfm carb, 262 extreme energy comp cam, Set total timing to 37 degrees give or take a few for altitude and such, 3.42 gears, welded rear, lightened as much as possible, headers and a GOOD 3inch exhaust. With that setup by girlfriends camaro runs 98mph in the 1/4 with a sucky 2.4 60ft. Better yet, do the same setup and port the stock heads and re-install with thinner steel shim gaskets............that should be good for another 25HP.

Dump the EFI? I'd rather have fuel injection than carb. Especially on a street driven car. You're basically going to get the same power if not more with fuel injection and added reliability.

 

i would agree if it werent cfi, cfi just isnt that great at all.

 

I'd say dump it no matter what EFI it has because in MY opinion (not the same view as other I'm sure) thirdgen F bodies came with DECENT efi systems, but NONE of them are that good at making loads of power unless extensively modified. I'd NEVER seen a TPI/TBI/CFI ect powered thirdgen in Tucson crack 13's uncorrected without an ASSLOAD of modifications or with the help of slicks, nitrous, and or supercharger Tim's 305 TPI 5 speed Z28 is an exception........but not really, I saw him run like a 13.6 uncorrected but I seem to remember him telling me that pretty much everything on that TPI system was aftermarket. Thats too expensive for me. So.............basically to each their own, but if you're poor and you want to go fast then your "own" is carb Kudous if you can make EFI fast on a budget though.....more power to ya.

 

Doh, double post
