What would it run?

[SVTdubs]

Ive gone 13.43@104.23 in my stock 97 cobra with an et street on the back.

what do you guys think it would run if I did these mods... all hypothetical of course...

JLT intake
o/r X pipe
4.56 gears
Xcal2 tune

also, with 456 gears, what gear and rpm would the car go through the traps?

[Ear Rak]

in this weather...i'd guess maybe a 13.2x once it gets warmer though i'd say it go back to a 13.4x 13.5x

[SVTdubs]

Im thinking 12.85's all day long.

[Ear Rak]

goodluck

dont think a gear, intake and midpipe will do that much though.

[02RedL]

Im thinkin waste of money.

[maniak]

i think you could bust out a high 12

[SVTdubs]

Id have all of it except the tune for 300 installed including parts

[dgussin1]

do it and stop being a pussy.

WHAAAAAT?!?!??? You saying he will only drop 2/10ths with those mods??? You have got to be drunk.

My bet is very solid high 12's in this cold weather and probably getting 12's about half the time when it heats back up on those cool summer nights.




Eric, I know you want 12's in that car but don't fuck around and waste your money on regearing now when you will just be switchin back within a year. Hell this season is over by all intents and purposes so if you were to switch to a 4.56 you would not even have much time to get your money's worth out of it before regearing back to 3.27's for the turbo. Patience is the smart thing to do here, even though it sucks major balls most of the time. I know you probably got more money crawling out your ass than I do, but why waste it.

[SVTdubs]

definately no money tree over here that Im aware of. Your right, I should just keep driving better and better and find a way to take some weight out while preparing for the turbos (ie, coilovers, k member, etc)

[N20GT]

It should do 12.8s in this weather. Chopping the cats off of that car would do alot. If im correct that car has 6 of them. And damn, a 4.56 gear? U dont fuck around. I never seen a bone stock n/a cobra run that fuckin fast, especially not a 97.

Do you plan to run a standalone like FAST when you go with the turbos??? My guess is yes so that you can run the low impedance injectors with the correct driver.

But if you plan to go with 72's or smaller and stick with your stocker computer and tune it with the Xcal2 then why not throw a tune on it for now? At least that way your not wasting much money and you can easily reflash the EEC too.

[CobraChris08]

I'm guessing 12.79 to high 12's all day long. That gear with slicks is gonna make a HUGE difference. U'll probably be into 5th half way once you hit the traps.

[Box 2]

high 12's for sure....lol on the lossing tenth's of a sec....do it and take her back next week

[1MEANGT]

She will go high 12's with that combo.

[venmousracer]

Eric Like I have told you before,

456 gear

alumium driveshaft, sometime you can get away with the stock driveshaft as you will encounter a slight vibe, especially with so many miles on your stocker.

cone filter and remove the mesh grill inside the maf

x-h pipe off raod

and a tune

Car should be a 12.80 car or faster with a skinnie up front my bogey's out back and leaving at the rev limiter..

4.56s are perfect for a N/A combo on that car. If you launch the car at 6500 RPM...which you will have to do to preventing it from bogging. The car should go 12.4s w/ that combo.

I went 11.99 w/ basically the same combo, but w/ less weight.

But I hate to tell you, your stock axles aren't going to last very long w/ that kind of launch.

There are new injectors that are high imp coming out, they are 83lbrs from s/d

Good call on the Alum. DS Eddie. Been so many years I forgot how I almost rattled my teeth out w/ the stocker and a 4.3.

The 4.56 will trap around 6500-6600 RPM.

[SVTdubs]

lol and all this in a week? right... I have a feeling it will be running stock this weekend but if they are open the following week, I may have something else done. Im going to stick with my current plan and maybe just get the tuner and drive this bitch into the 12's somehow. We will see what happens

[TSI_SVT]

10.99

[Blood on Blood]

Eric, you will probably hit mid 12's. Granted if you plan on throwing on a turbo, the 4.56 may not be the best option for a street/track car.

Use the following as a measurement -

The T-56, which my 03 Mach 1 has, runs a 1:1 gear ratio in 4th and a .62:1 gear ratio in 5th/final gear. If I was to throw in a 4.30 gear on the stock 17 inch tires:

Red line in 4th would be at 119 mph and then have to shift into 5th/final gear.
80 mph is 2800 rpms in 5th/final gear.
Going through the traps in 4th is around 6400 - 6500 rpms w/ a 4.30 gear.


Compare these specs to your transmission. Naturally aspirated Mach 1 owners are typically running the 4.10 or 4.30. Many feel the 4.56 is too much for a daily driver/track car.

Oops, I said 72's didnt I? I meant the 83's. I knew that there were some new high imp 83's out, just forgot who makes em. From the amount of power I think he plans to run 83's may not be big enough. Shoot, I would drop in some 96's and shoot for 1k!!!

[WhtSuperStang]

high 12's for sure, and ur gunna be running through the traps in 4th....
