Sounds about right for me....stock for stock.

I was wrong about the 13.26....it went like this
60ft-1.93
330-5.533
1/8mile-8.522
mph-81.97
1000ft-11.111
1/4mile-13.297
mph-102.98
Gears, CAI and exhaust.full weight car 178,000 miles. Street tires as referenced by the 1.93 60ft.

300bhp/ton

I don't doubt your claim. But the numbers don't add up.

I've done some searching and the best 0-60mph time I can find for a 5.0 Mustang is 6.2 seconds. However this is only once, most are 6.4 seconds, and also 7.3 seconds for an early 90's example. And 8 seconds for a early 80's example (82).

Now an Fbody should be knocking out the 0-60 in around 5.3 seconds if you beleive the mags. And this would be an auto as well. I've seen quite a few claims of 4.9x seconds for M6 cars.

So even worst case scenario the Fbody is still 1.1 seconds quicker to 60. I can't beleive it makes up that time in just 10mph (50+ as you claim).

I think there are 3 reasons for this.

1. For the first 30 feet or so most cars will be pretty even regardless.

2. As the 5.0 have less power I would assume they are quite easy to launch without roasting the tyres too much, thus being quite consistant 0-60mph.

3. The Fbody's have WAY more power so its far easier to spin the wheels and loose time. In addition the 10 bolt rear is not all that strong so I think many people do not give it as much abuse as the engine can offer, knowing that the car will make it up once moving.

I still dont understand how the vast majority of them at our local tracks run very low 9s to high 8s. I can hang with them easily till the end of the 1/8 mile.

BLKWS.6

Lets put it this way as to the last 10mph it was enough for the LS1 to pull me by a good 1 car+ when he had been at my door (this was in my former LT1 A4 2.73 w/CAI and the race was against a lightly modded-exhaust,tune,cold air LS1 A4 from a light and we both got a good launch.) THe point is, the LS1 makes 365(TRUE) lb ft of tq while the 302 makes about 300. the 302 makes max tq at 3500 while the LS1 makes it at 4400, the LS1 weighs 3-400 lbs more. Now do the numbers make sense, forget what you read in the magazine, just take a look at THOSE numbers, it SHOULD make sense. I mean, afterall, i remember reading how an automatic mustang gt 04 ran 14.1 or something and i remember seeing how it ran 15.1 in another mag, clearly there are DEFINITE variations from truth and magazine if the magazines are a full second off. I even saw an LT1 F-body quoted at something like 14.9 IN PRINT.

And my point was if your doing H/C/I why would leave a stock gear in the car. Its probably the first mod any Mustang guy does to his car. And Ive seen Fox cars with 270 rwhp run in the low 12s. Hell I did with 309 rwhp. 12.30@116.

Sukkoi19

Where are you getting your 0-60 times, because if its magazine times then Ive seen 14 second LS1s. Like I said whether or not its accurate, it is repeatable and comparable my LS1 and 5.0L were within a tenth of each other on the G-Tech.

Ok, at first you didn't mention the gear and 5spd. It is still the best time I have ever heard of though!! A stock 178,000 mile 5.0 has about 180rwhp, add to this 10rwhp tops for the CAI/exhaust. Soooo, with ~190rwhp you ran 13.29 with a 1.93-60ft--incredible! 99-04 GT's with 230rwhp stock and 1/3 of the miles are running 13.9-14.1 at best.

The 4.6 is dohc doesnt make good torque down low and is also a heavier car.My fox has the same mods and an e-cam and ran 13.30 1.773 60ft but I figure it has 260 at the wheels 300lbs of torque. Sounds about right to me.

The 4.6l makes similar torque #'s only at a higher rpm, which is where you spend your time racing anyway. The pre 94 gt's do have a weight advantage though.

mattkimsey

I'm not questioning a gear being a usual first mod. Sure, you can throw in a gear and slicks and become a hole shot car, but that wouldn't be a fair comparison to a stock fbody on regular radials. You could also throw a gear and tires on a fbody and run faster than a 03 Cobra. I bet a H/C/I fox, even with a gear on street tires wouldn't run too much faster(.2-.4) than a well driven LS1 fbody. That includes the fox staying emissions legal, full accessories stock weight, stock bottom end and off the shelf HCI--assuming 280-290rwhp for the fox.

mattkimsey

230rwhp is for a SOHC GT which makes just as much low end torque as a 5.0. The weight difference is probably less than 200lbs.

It seems like a lot of magic surrounds the Fox bodies---buy a 170,000 mile 5.0; throw in a gear; weld on some mufflers and go huntin' LS1's

haha another bites the dust!!!!...ls1 rules the asphault!!

Well i guess if you over looked the e- cam and the other bolt ons i have [short attention span i guess]but it is kind of magical when a fox body car tears an ls1 a new hole at the track.

mattkimsey

It would help if you read the whole thread,[or atleast the page] so you would know who I was referring to. He has gear and exhaust(cai is useless)

mattkimsey

Oh, and Kenny....260rwhp with an e-cam aint gonna happen.

Ok fair enough mr dyno how much power am i putting out ?my car is 3330lbs and ran a 13.30 you tell me how your calculations came out .

mattkimsey

With an e-cam and exhaust....probably <205rwhp.

OOOOOOK Just say no to crack dude !

Yeah, no way will you make 260rwhp with stock heads/compression and an E-cam. Not gonna happen. The little old E-cam would have to be worth 40rwhp to make those numbers.
