I am hoping some people with track experience can give me a better idea of what my car is capable of. First time to the track today (was only able to run twice) and the best run I had was the following:
I was just pedal breaking it off the line and had horrible traction issues. Not realizing my tire pressure was WAY too high it was at 34 PSI on MT ET Streets (255's). I was told to bring that pressure down to like 15-17 PSI and it would run a hell of a lot better. Anyway, I was shifting at 5500 (I am switching out my 6k pill for a 7k and will be shifting at 6500 next time). Any ideas what my car will be able to run with traction and higher shifting?????? Thanks guys.
yup...that 109mph is good for about a 12.2...that 60 SUCKS...and the 1/8th really sucks....
your mph is AWESOME....sooooo...lower that tire pressure...launch that car hard...and shift on time...you should have a 1.5-1.6 60 ft.....a 1/8th in the 7's....go back out there and good luck!

i got a v6 2001 with a few mods and i hit about 12.3-12.6 in a quarter....but i deff dont hit 109mph... more like 125mph to 130mph... honestly i have always hated mustangs til i got this one. v8's are overrated. i love killin those gt's and still getting 420 miles to tha tank!!! =D
well based on the 1/4 mph it should be it be running low 12's to high 11's
not to sugar coated the 60' is bad....
if i wasn't a mod i'd say your 60' sucked..... (not suppose to say things like that..)
get that car to hook and it will fly.....
ha ha yeah I can't sugar coat that 60' either...I know it was pretty bad thanks for the predictions!

A 2001 v6 with a few mods and you are running 125 MPH for your 1/4 mile???? What do you have done to it?

V8's overrated? dont think so...
your mph is good for 10 second passes....turbo? supercharger? nirtous? You definately have a power adder to run that mph...
but 12.3-12.6 in the 1/4 isnt going to kill ANY V8 with a poweradder...
i'm sure your car isnt hooking at all

Please note the highlighted part of your post.....
as a rule I am a very diplomatic person but in your case i will make an exception.....
i will throw the BS FLAG
the last time I was at the track my car ran 10.43 @ 126 mph
so you expect me to belive you ran a 12.3 @ 130 mph.....
so if you are going to bring something to the table please make it honesty....

Ha, ha, you beat me to it! As I'm reading this post I'm thinking "Holy major BS batman, who's this guy think he's talking to?" At least try to make the story you tell somewhat believable.
To the OP, what's your combo? There's probably a lot more in it than what's indicated from the little info we have here. My thoughts are as follows:
109 mph in the quarter says low 12's should be possible.
However you ran nearly 91 mph in the eighth. Most cars pick up 25-26 mph from the 1/8 to the 1/4, which would give you 116-117 mph for the 1/4 which should be mid 11's. I don't know why you didn't pick up more speed on the big end. Something 'aint right there. I run 89 mph in the eighth and 117 in the quarter.
Traction issues don't have a lot of effect on trap speed so that's why I'm looking at it as an indicator of potential.
One other way to look at potential. It's been said that every tenth you can improve your 60 will show up as 2 tenths improvement in et. This seems about right to me. Going by that, if you take your 2.551 60 and shave it to a more reasonable 1.7, those 8 tenths better 60 will be 1.6 seconds improvement in et which would then give you an et of around 11.4
We can toss numbers around till the cows come home but the bottom line is there is a lot left in your car.

haha i kinda forgot to mention i never wanted to drop my tranny so i dont spin out starting. cuz i dont think the t5 tranny's can withstand torque over 300 lbs.. which i have somewhere around 310lbs
and all i got is the cai, full magnaflow exhaust, a predator tuner, and a few pounds taken out of the car...around 160lbs.
BUT. i have a question. i have stock 19lbs fuel injectors..(i think) with out forced air induction how much of a hp boost would i get with 30lb jectors?? (i dont have enough cash for a 3000 dollar supercharger)
idk. but i dont want anyone to think im an idiot. but thats why i ran low 12's actually i asked about is it possible to swap out the t5 tranny on my v6 for a t56 like a corvette or viper tranny.
no one has responded on it so if you wanna be awesome in my book and answer it i would be very greatful.
So what we have here is a basically stock V6 with well over 500 hp, since that's what's needed to run 125+ in the quarter with a 3200 lb car.
Nah, I don't see any BS there!
On a more serious note, why do you want the T56, they're pretty pricey you know. Personally I will go with a G-force T5 when I feel the need to upgrade my transmission. A lot of guys use the TKO's too. Unless your heart is set on a 6 speed and you have the cash, I think there are better options.

275rwhp 318rwt
and i just weighed the car in at 2942lbs
my car is a lil over 10 pounds per horse, you dont need 500hp to do a 125mph. seeing that a corvette z06 has 505hp and does a quarter in 5.7 secs.
trust me i use to drive a first gen talon tsi awd. that had 260bhp and since it was all wheel drive i cranked mid-high nines in a quarter.
and for the tranny i never checked any others than the t56 i just saw that the cobras used them so i thought why not.
the t56 im looking at is 1300 dollars. whats the g-force?

mmb617, that's a lot of great info...I really appreciate it.
Yeah, I def. think my top end is suffering. I can't remember if I hit the rev limiter before finishing (I am pretty sure I did), but I do know I was shifting around ~5800 and the motor is supposed to shift at 6500...so I am just waiting on my 7k pill. The guy who built the motor for me seems to think that 112 MPH is about the most I will get out of it because the top end of that motor isn't the best compared to the low end power it's making. Also, I have a crumby 9" air filter on there due to hood clearance issues so I am sure that doesn't help any.

I'm not sure why I'm arguing with you other than it's a rainy day, my car's as ready as it's going to get for track opening day, and I'm bored.
At any rate a 2942 lb car with 275 rwhp will never hit 125, or anything close to it in 1/4 mile, from a standing start. I don't think you'll find anybody who will debate this.
A Corvette does the quarter in 5.7 seconds? Now I know you're just kidding about this one. It couldn't come close to doing the 1/8 in that time.
Then there's 260 hp and mid-high nines in the quarter. That car better not weigh more than 1200 lbs with driver. Are you sure you're not talking about a bike here? A 260 hp bike could do it.
I'm guessing that you're either a troll just looking to stir up something, which is fine, I'm bored too, or you really don't know anything about cars and racing.
Oh, and a G-force T5 is an upgraded version with better shafts and gears. They can also be ordered with a stronger case. The main advantage is they are a direct replacement for a regular T5.

Oh good, some intelligent conversation. I am very interested in talking to you because our combos are fairly similar. Perhaps we can help each other. As far as a comparison of our cars goes:
I have an '85 GT which is more strip than street, so it's probably lighter than your car, but maybe not that much.
I have a 393 with about the same compression, so your motor's a little bigger.
I have ProComp heads so I'm reasonably certain your twisted wedges are better heads than I have.
I also have a mild cam, it specs out to: .507 intake lift, .499 exhaust lift, 232* duration @ 0.50 intake, 236* exhaust, with a 111* LSA. I would doubt if your cam is any milder than that.
I have a Holley 750 DP carb, so similar there.
I still have the P/S and belt driven water pump too.
I run a T5 with 3.73 gears.
So in looking over the differences between our cars the advantage goes to you in just about every comparison. That means you should be able to run faster times than me. I was running high 11's at the end of last year with a bone stock rear suspension which was keeping me from any kind of decent launch, the best I could do was 1.7's. Since I upgraded my suspension over the winter I fully expect to run mid 11's this year. You should be faster than that.
I'm not sure why your builder thinks that 112 mph is all you can do with that combo. What's the limiting factor? These big strokers don't need to wind up real high to make good power. I have found through experimentation that although my motor will easily wind to 6k, there's no power up that high. I run the best times when I shift at 5500. I go through the traps at 117 and I'm turning about 5600-5700. With your 4.10 gears if you can cross the stripe at 6500 you should be around 120 or so, which is flirting with the 10's.
What intake are you running? I have a vic jr and I believe it will flow all I'll ever need. The weak point in my combo is the heads. If I could afford better heads and cam I feel sure I'd run 10's and like I said before, you have a stronger combo overall than I do.
Are you running the drag radial version of the M/T et streets? I don't know why they call the radial and bias ply version by the same name, that always confuses me. I run the M/T drag radials in a 2.55/60/15 and usually run them at 18 lbs. I tried lower pressures, but 18 seems to be the magic number for me.
If you think the air filter is hurting you why not try pulling it at the track? Maybe your lack of top end grunt is something as simple as that.
What kind of suspension do you have under your car? Good suspension pieces will help you hook, but seat time is probably your biggest friend right now. With practice you should be able to knock a lot off your 60 time even if your suspension is stock since you already have some decent tires.
You're at the point right now where every trip to the track you will see big improvements. Keep at it and you'll be running some good numbers in no time.
