if i lost a race i would post about it. but i did beat him. in 3rd we were neck and neck i hit 4th and pulled away. im waiting to run him him from dead stop. i think id lose that race but not by much. and paul i dont care option never crossed my mind... no the sun didnt go down before race ended lol. my car is shit looking and sounds like shit but its still quick i wont say its fast for being a stock motor because i have not ran the 1/4 and had proof of what it can do. until then its my 5.slow. justinschmidt- im unsure of my gears hes got 3.73. with an auto trans top of 2nd at 105mph seems a little crazy to me. but i have not owned a 4.6 so i couldnt say true or false.

Lol, has nothijng to do with a 4.6 or 5.0 its all in the gearing and with stock 3.08 gears and the auto trans gear ratios, thats how it would go.

3.73s in an auto will still do about 75-80 in the top of second gear....his car would downshift into 2nd gear if he floored it at 35 mph too...you cant hold 3rd gear in an auto like that.

I'm going to guess that this was a NPI headed 4.6. A PI headed 4.6 will walk all over a stock geared bolt on 94-95 5.0, from any speed, for any distance.

I would love to see that PI 4.6 up against 5.0 because I see too many modulars go down to my stock 5liter coupe...

When you say "coupe", do you mean Fox coupe, or 94-95 coupe? And are you racing NPI 4.6s, or PI 4.6s? Because you said something after my NPI comment, I'm going to assume PI 4.6s for this post.

If you mean Fox coupe, you might have a chance because of the 300-400 pound weight advantage (assuming both are stock, and everything else is equal). Even then, that's a 'might', and you would probably still lose if the 4.6 driver knows how to drive.

If you mean 94-95 coupe, then no. BS. The 99-04 GTs (i.e. PI headed) have 50ish more rwhp peak to peak, 15 more rwtq peak to peak, a MUCH wider powerband, and more/better gearing. Stock for stock, there is no comparison. A 94-95 runs low 15s in the 1/4, a 99-04 runs low 14s.

It's like me having a stock 01 GT and running around saying, "Oh, I regularly take down 03-04 Mach 1s..." No, I don't! If I ever did once or twice, it was probably because the other driver wasn't trying...

true on powerband the 4.6 i ran goes to about 7rpm range as where i shift near 6 range. the 4.6mod is a sweet engine. thats why cops roll in crown vics as compared to a chevy car they just outperform.

Pi cars with ported heads and aftermarket cams see peak power around 6-6300 rpm... not much higher.. The manifold restricts it...

Well I was talking about fox coupes, sorry I didnt say but the foxes are hard to beat. I would like to see that modular beat the coupe because I know the fox will leave it in the dust... somone might want to do alittle more research about stock fox coupes and what they run...

wtf are you talking about? Stock fox coupes arent fast. They are the same as 94/95's except they may weigh a tad bit less. The damn things probably struggle to get into the 14s.

case and point
"I ran my bone stock 91GT 5 speed with 2.73 probably 100 times and I averaged between 15.1 and 15.3 at 93MPH leaving just above idle. "
"My best run STOCK went like this: This was one of my slowest reaction times though.But that doesnt affect your E/T.

R/T: .371
60': 2.328
330: 6.549
1/8: 9.942
MPH: 73.20
1000: 12.834
1/4: 15.267
MPH: 92.70

Either way, there may be a handful of great drivers with drag radials and a few mods that got into the 13s but on the street, a PI 4.6 car will walk away from an old 5.0.

Sorry, thats just the way it is.

No, a Fox will not "leave it in the dust."

And to be clear, we're still talking about PI headed 4.6s....

I'll say it again: the 99-04 GT has 50 more horsepower, a wider powerband, and more gearing; while a Fox coupe weighs maybe 300 pounds less. One of the factory-freak Fox coupes with a hellacious driver really banging the gears MIGHT (and I emphasize 'might') run along side a half-way decent driven 99-04 GT. There is no "leaving it in the dust". I'll revert back to my last analogy of saying a 99-04 GT will beat an 03-04 Mach 1. It just won't do it, there's not really any argument.

I know what they run. An EXTREMELY well-driven Fox on a great track with great weather conditions will click off a 14.2-14.5 if everything goes good. 'Typically' driven 99-04 GTs will do that on a regular basis in much worse weather.

I think someone needs to do some research on the PI headed 4.6s and what they run....



I've got a racing calculator made in Excel that plots speed to (the torque on the wheels)/weight of 2 different vehicles. I've tested it with several vehicles, and it is pretty accurate. If I can find some dyno graphs of a stock 5.0 and stock PI 4.6, I'll post up the findings from it.

pull up to a cop with a vic in a stock 5.0 race him guaranteed ya get whooped mine is modded a little and i know i will lose

And.....what's your point here????

The FASTEST Crown Vic's (the 98-2011 models with the PI headed 4.6) run mid 15s (at best), so if you can't run that, then you are only further proving my point. If you can't keep up with a 250 horsepower 4.6 motor in a 4500 pound car, how on earth are you going to leave a 3500 pound Mustang with a 265 horsepower 4.6 motor "in the dust"???

And no, I wouldn't "get whooped". There are VERY few mid-12 second Crown Vics out there, and I doubt any of them are owned by police departments.

You should read that again...he was saying that a stock 5.0 mustang would lose to a crown vic 4.6 lol...although Im not sure how true that is....maybe the police force hooks them up a little bit.

Point is, stock 5.0s dont beat PI 4.6s in the power department....The end.
