Well, I have a few things I want to go over and tell. So, I got my car back last tuesday. I haven't floored it or anything, because I wanted it to get some miles on it since I got a new crank and bearings. So, just last night I'm driving to go and get something to eat. I noticed an 05 black Mustang GT and I was behind the person that was next to him at the light. He goes through the intersection rather fast and the car sounded like it had exhaust on it. It was a bit too loud for it to come out of the factory like that. Well, I pass the guy that was in front of me and get next to the GT at the light. I didn't want to race him because I still wanted my car to break in a bit, but I have always wanted to see how fast these things were. Well, we kind of give eachother a little jump on the line, letting both of us know we are going to go. When the light turns green, he doesn't floor it and we roll to about 10mph and then he just punches it. I couldn't resist, I got on it and I started sliding all over the place. (no traction) My car shifted a little early due to the spinning in first and as soon as I got in 2nd I started pulling pretty good and I kept pulling through 3rd. Even while I was spinning, he never got ahead of me. By 3rd gear, I was about 1 car ahead. After the race, I felt bad that I floored it, but good that I won. (the GT was a manual by the way)

Just wondering, since I got a new crank and timing chain and bearings and all that, would it be wise to not floor my car at all? I would think that I should be really easy on it, am I right, or does it really not matter? I also decided to go with a high volume oil pump, since all that was getting changed. I just want to make sure It wasn't horribly bad for me to get on it there. When I first got on it while I was racing the GT, I was feathering the throttle so I could get more traction, then slowly laid into once it hooked...

By the way, the mechanic said that my underdrive pulley is moving a bit. He showed me and suggested I put the stock one back on. He explained how the aftermarket ones don't have a harmonic balancer that come with it. Well, I kind of want to keep the underdrive pulley, because it is a little power. I mean, I would keep the alternater pulley, but I would be getting rid of the shiny one. Not that it really matters, but do you think it would be better for the car to just put the stock one back on? Do you think I would notice a difference in power?

 

13.6 stock. Ive beatin one.

 

i've seen a couple bolt on 05's go 13.8

 

I've seen low 13s stock in good weather and with a good driver, otherwise at the track in auto and manual form I've seen 13.6-13.9. I took one on the hihgway last week on mon (my bday, kill story is in street section) by 2 car lengths from a 60-95mph roll.

my buddy beat one in his 2006 Cobalt SS/SC... that was to 70... and i beat my friends cobalt (96 LT1)... i dunno. The guy in the mustang was PISSED that he got beat by a 4 banger

 

'05 Ford performance at '97 Chevy levels. Granted, the Mustang is a nicer, better engineered/built car though...

 

I heard the automatics were a little faster in the quarter. They don't have the same mph, but the automatic gets a quicker quarter mile, while the manual has a higher trap speed. Is this true? Also, does anyone know what Mph they trap?

 

I have a friend that has one and with ET streets,intake and exhaust he has run 12.40s @108. when it was stock with just an intake it went 13.1 @106.
They can run real good with the right driver.

 

Your thinking Mach1...as we all know the 05GT just does not make enough power for anything in the low 13's. Buddy of mine did everything he could to break 13.6 and the thing just didnt have it in it.

 

From my experience racing them at the track and on the street, they run about what an LT1 F-body does.

 

There's a member on here (seen him in the street racing section) who has an 05 GT (m5 IIRC) with a a few bolt ons and sticky tires running 13.1s

I think I read somewhere that the new 'Stangs have a 5-speed auto, which would allow slightly better gearing over a 4-speed.

 

You mean 5-speed, right? Also, anyone have an idea about my other question?

 

Owner i would let your car work it in for a few hundered miles. Just in case. But thats just me.

 

Hope you didnt put one of those POS stack on UD pulleys WITHOUT the balencer stacked on(Tis is why they come with longer bolts than stock).
However if your mechanic doesnt know this about the lt1, you may want another.
If you want to run an UD BALENCER, you need a ASP UD Balencer. THey are a true balencer.

 

Honestly, I don't think the underdrive pulley I have on my car came with a balancer. After I got all the work done to my car I noticed it looked a little damaged. Sure enough, when the car was running it had a wobble in it. He said I should put the stock one back on so I have a harmonic balencer to keep it straight. He said I would lose a little power, but not much. So, I can get an ASP UD Balencer that will go on to my current underive pulley, or do I just need to completely buy a new set? I know they are march underdrive pulleys. I think the look up is 04485

Should I just go back to the stock one? Would I see a difference in my track time?

 

The ASP one will run you around 150 dollars or so and isn't a stack on type deal. It gives a 23% underdrive and also weighs about 2 lbs less than the stocker (less rotational weight). For now if I were you I would just put the stock one back on, and if you do get another one I would either get the ASP one or invest your money elsewhere.

 

Do you even notice a difference in quarter mile time with underdrive pulleys?

 

UD pullies make minimal difference.
