this should give you a good idea

http://www.albeedigital.com/supercou...0-60times.html

not exact, but close enough

EDIT: maybe not, our cars aren't on the list

You're probably looking at high 6's

Wow that is actually awesome. For some reason i thought they were more along the lines of 'high 7's, low 8's' . This is a pleasant surprise!!!

torque helps

It gets overlooked in today's market, because 4 bangers don't have enough to talk about, so they don't.

Hey man i can't complain. I'm actually really happy it accelerates that fast. I was seriously under the impression that our cars were slower--but like i said-- im not complainin at all!!

(and i've only driven my car once when we bought it on Saturday, so i wont really be able to get a feel for it until we pick it up later this week)

a mack,

With only 45,000 miles that was a pretty good find. Mine only had 33,000 on it when I got it 4 yrs ago. Low mileage thirdgens are getting harde to find.

Yea it actually ended up at a new car dealer that my parents had bought 2 new mercurys (villager and mountaineer) from... Some old gentleman had the car since it was new and traded it in about 3 weeks ago on a new ford explorer. I know what your saying about the low mileage 3rd gens. We've looked [on and off] for the past year and a half until we found this one. It's in absolute magnificent shape. I do admit that i'm very lucky to have found one like this. We're going to pick it up from the dealer on thursday--thats when the fun begins!!!

I'm with dimented on this one. I could see a 5-speed coupe, no A/C car maybe getting into the low 7 second range, but 170 hp just doesn't push a 3500-3700 lb car into the 6's.

i love it when people look at my odometer and say "wow, she's only got 12K on her!?"

Um yea....got nothing to do w/ the fact there isnt a spot for the 1XX,XXX lol

I can never even guess a 0-60 b/c my speedo does this "floating" thing. If i can dig up that accelerometer again though and go to the track I could find out.

Yeah, bone stock I'd say high 6's at BEST. And thats with a phenominal tune and new plugs/wires/cap/filter/oil/ect. 170hp/255lbft just wasn't really designed to push these sleds like rockets....

6 flat with a 2.25 in full length exhaust + cat. Stupid *** mechanic that worked on my car decided to put that on for emissions.

Ill race ya, jon, but you have to put your stock exhaust back on.

Ive been tweaking the tune so my AE is all out of whack again. Had to slowly roll into the pedal. If I couldve mashed it down, it might have been in the high 5's range, but thats still slow for me.

Its probably even a little slower, now. I noticed that there was a step forming between the lower parts of the MAF table that I tuned and the upper parts that I didnt (underreporting the flow). I could also smell rotten eggs the whole time in PE so it wasnt quite getting rich enough to shut the cat down. I dont like loosing power, but I really dont like having a cat melt solid. Engine wont make any power then.

*** I hate cats...

Dim, I too hate cats and mine was also starting to smell like rotten eggs before I took it off. I guess I'm keeping the motor happy, just not the damn converter.
Also, yes, AE is a royal PITA to tune with TBI. Even I haven't gotten it dialed in yet with the Ultimate TBI code. Ever think about using the MAF just for the normal sync pulse width and having the AE all TPS and MAP dependant?

Hey JP,

This is off topic, and honestly doesn't deserve a new thread. But can you recommend anyone in the Central Jersey area who can bore out a stock throttle body (TBI), to two inches? Should I just take it to Eddie's Valve Grinding and call it a day (not sure if he'll do it though, will ask him tomorrow), or are you aware of other's?

Thanks!

Thats exactly how its set up, and its still a pain to tune. There was no way Id ever switch over to the LV8 or anything like that. Change the ammount of fuel delivered by the MAF, or the timing for that matter, and the AE needed changes. With the open exhaust, the MAF took care of most of the AE and then some as there where massive airflow spikes when the throttle opened. With the cork stuck in there now the spikes are almost non-existant. AE is just like the VE. Change anything and all your hard work to dial it in goes right down the drain.

One thing I do like about the cat and closed loop is that the exhaust is clean and odorless. And theres that whole good for the environment thing, too. Without the cat the car would stink up the world. I really didnt like smelling like exhaust after working around the car or driving it in heavy stop and go traffic. But, I really, REALLY dont like having to accomodate the cat.

well maybe a little. that was with it in drive. i could prolly do a little better if i wound it out. but its had regular tune-ups if needed or not. but i think the power loss is in the 700r4 simply because (IMO) it shifts too soon and it slips a little between 2 and 3. or maybe theres just no power to lose. ive got 273 gears also.

0-60 you definitly shouldnt be shifting 2-3. 700r4 w/ 2.73's can hit almost 90 in second gear. less you ment 3.73
