Default 384rwhp running a 10.90 second 1/4 mile?

Possible? I'm on another mustang forum and one of the users states he has a 69 mustang, unsure of the motor but has 384rwhp with a 200 shot of nitrous, does a "10.90 second 1/4 mile without spraying," and weighs roughly 3,300lbs. Any feedback? I know 1/4 mile calculators aren't 100% accurate but are usually somewhere in the ballpark and they say at 3,300lbs you'd need about 525 flywheel hp to be able to get in the 10 second range. That and the z06 corvette doesn't even do in the 10's with approximately the same body weight and what 550hp? The same goes for the 13 Shelby GT500 at what 3,800lbs and 662hp? I know that his car is probably in no way set up like these two newer cars but it doesn't seem possible to me. Anyway, I'm just curious... thanks!

I call BS. I have a Mopar friend who runs a full-race '68 Dart with a monster naturally-aspirated 512ci (440 stroker) motor, and he only recently dipped it under 10s (9.98), and that was after swapping to a 4-link rear suspension. Before that, it was in 10.2-10.3 territory. The previous 500ci motor put it down the track in ~10.5s. I'm betting the stripped-out Dart weighs less than the Mustang (even with the big block), and has almost twice as much power.

No way is the Mustang with 384hp running 10.9 without nitrous, a lot of weight reduction, and some significant suspension/traction aids.

My thinking as well... I have a 351w in my 65 fastback with 375rwhp and it only weighs 2600lbs... guess that means I can run 10 second 1/4 mile times too huh?

10.90 in the 1/8th with his ****ty driving missing shifts and scraping the barrier on the way down? That might be what he meant.

He's full of **** if he thinks a 3,300lb car will go 10's with under 400 at the wheels. I could see it on the engine if it had massive weight reduction and massive suspension.....like, perfectly tuned suspension with some crazy *** 60' times and it weighed 2,000lbs.

Some people are bad liars (they don't even tell believable lies) and some people are just plain stupid. I used to work with a girl who owned one of the new Chally SRT8's....she was absolutely convinced the car ran mid 11's off the showroom floor.

well, its getting cold outside again...****in reached down to the 40s the other day.  almost can't wait for the snowy stuff............................almost i don't have a twitter account nor have i ever been to a twitter web page (update: i have), but if i ever did decide to take the plunge i will let you know by posting it in this awesome little box of text (update: not really)! i like tacos lol...though between crunchy tacos and soft tacos i cannot really say which one is better.  sometimes, the mess a crunchy taco leaves behind is a little annoying while the soft taco just doesn't have the same taste... cake is so much better than pie no, srsly.  **** pie. ****ing

Must be one violent superb launch...however if the calculator claims 525 would be required at the crank for that weight to hit tens, then the 384 at the wheels isn't too out of the question if its an automatic car. That just seems like a great weather/DA day time though at best. Video?

We always figure 12-15 percent loss from flywheel to pavement so 574- 12%= 505rwhp or 574- 15%= 487rwhp needed. So calling BS on this one.

Some people say the stuff on purpose to troll. That could be what is happening here.

If the car in question is a 1969 Mach 1, then yes he is trolling you hard. He does run in the 10s with no NOS, but his HP is way higher than what he told you. haha

Well....I have 400 RWHP (396 to be exact when it was dynoed 4-5 yrs ago after which I have done nothing...haven't even changed the plugs) in my 65....has run a best of 11.2 at 121 (just a couple months ago in fact)...not launched, in street trim (front 1 1/8 sway bar still bolted together), 235 40 17 tires on the front and 275 40 17 drag radials on the back. I'm convinced it would run a 10.9x if I was a better driver.

not apples to apples but my buddy had a 99 supercharged GT that dynoed at 399 hp and ran consistent 10.95-10.99.It had a lot of the interior removed and minor suspension mods.

@ dodgestang -what do you weigh in at? a 65 weighs in at 2600 or so, and the OP stated 3300lbs. 700lbs=big deal.
