Anyone want to take a guess at my rwhp and 1/4 mile/trap speed? VIDEO: 40-120

So I have been having a lot of fun with the ol' Stang over the past year with it being boosted. I have been curious lately as to how the car should perform in good conditions. While I do intend to go to the track eventually, I do not really plan on going to a dyno as I am extremely satisfied with my Lito tune.

With all that said, the car is a 2005 GT, 5 speed:
Paxton 2200SL at 9 psi, Lito Tuned, 6200rpm shifts
supporting fuel mods
o/r x pipe, borla mufflers
4.10 gears
28" rear street tire
weight reduction, car should weigh around 3500lbs without me in it

I'm about 1000 feet above sea level so I know that robs 5-10 whp, and the heavy 20" wheels have to rob another 15 whp or so, compared to drag wheels.

Here's a video of 40-120 pull with my current setup I just listed:


My guess for the track is 11.9 @120 and dyno 465 rwhp / 430 rwtq

Then once I do light Corbeau seats and SVE drag pack wheels/tires, I'd hope to run 11.5 @122 and maybe dyno around 480 rwhp / 440 rwtq.

I know elevation, dyno settings, track prep etc. all have an effect, so when estimating just use "normal" variables.

Thanks

This is one of those things where if you have your ET, trap speed and weight you can get a pretty good idea what your rwhp is or if you know your rwhp and weight you can get a pretty good idea what ET & trap speed to expect but without knowing any of these variables.. Although I think your numbers are probably pretty accurate. Originally when my car had a stock motor in it I had a Procharger P-1SC-1 making about 10 PSI with exhaust and 4.10's (my car was auto trans though) and it ran 11.80's around 115-117. A little later on I installed an FRPP intake, NSR cams and dyno'd at 440rwhp.

Thanks guys. Yeah the 11.9 guesstimate was on street tires. I've seen a Turbo 3V on YouTube with 20" street tires and 470whp run like 11.8 at 120. I think on drag radials and another 15whp he ran like 11.3 at 122. So thats where I was getting my estimtes from.

I'd be a bit dissapointed if I didn't run at least high 11's and trap 120. 500whp Cobras trap that and better and weigh a bit more.

Hopefully in the spring. I'm not going until I get a drag wheel/tire setup. Don't plan to launch it too hard but would still hope for a 1.8 or 1.9 60 ft.

Oh, well I based my ET guess on your current set up with 20" tires.

Mean while, five oh brian does 11.5 secs on his NA 2014 auto, with drag tires and a 5 krpm stall converter, and everything else is bone stock oem.

This literally has zero to do with the title of the thread... Getting out of the hole and having a decent trap are obviously 2 different things. Ive already mentioned I'm barely at the track and run my car on the highway/backroads most of the time. What makes you think I care so much about ETs as opposed to traps... My car is completely capable of low 11s, thus beating Mr Brian that you seem to be riding on the coattails so hard of. Doesn't mean I'm willing to bust up the stock clutch right now just to prove a point... Really not that uncommon for a 3V on 8-9psi to run low 11s with a good launch. Don't even start the nonesense of well Coyotes still have more potential, Yeah... And you pay for it... I fail to see why people compare vehicles in 2 different price points. 14 GT500s run a 10.9 all,day long on a tire... Guess you and Mr Brian are just a bunch of fucking schmucks for buying the inferior car... Get lost you fucking mongrel.

Btw I'm done with this thread and won't be checking back on it or replying anymore. There were a few people that gave meaningful answers, then all the smartass motherfuckers, that literally have nothing to offer, start entering the thread. Like really, if you troll forums to make,smartass comments and add absolutely nothing to the OP, your life is officially worthless. Strap yourself to a railroad track.

I have a 2010 4.6 3V + 6 psi, that's it. No coyote. 285 street tires. It's just a street car.

I find it interesting that with all that power and your proposed drag pack wheels + tires, you estimate a 11.5 sec et. You may well be a lot quicker than that. Hey, if it pulls good and hard in 2nd + 3rd gear..and the 1st little bit of 4th gear, that's plenty good enough for your local back roads.

If five oh Brian ever adds LT's + 93 tune, he will be booted off every track in his area. 'Come back with a full cage setup.' His best time is 11.45 @ 118 mph. His combo of high 5k stall converter + DR's does work. His weight is 3650 lbs. His point was his combo works good for his weekend drag racing outings... with no blower and minimal mods.

For starters, I will apologize for my brash comments on the last response. No excuse, but I had a nasty hangover and was a bit irritable.

Also, I clearly misunderstood the point you were trying to make. There's so much coyote nutswinging, and 3V bashing, that I I thought that was your point.

With that said, how is it possible he can trap 118 with a 3650 lb car, and less than 370whp, when you have some guys struggling to trap 118 with 430+ whp in the same chassis/weight range? I always thought trap speed was pretty closely correlated to power:ratio, or am I off base here?

For example, if I got my car down to 3400lbs and made about 490whp, I'd have an identicle power:weight of a C6Z, therefore I would expect a very similar trap speed, but not necessarily ET. I know gearing has some to do with it. But for lower speed cars it seems aerodynamics don't matter a whole lot in the quarter mile.

Crippled with the 3v.

New GT500 in 2020 for you!
Hey man, I clearly misunderstood your last post. Also I was on mobile so I couldn't see your signature (3V stuff), got all defensive thinking you were a 3V basher lol seems like any post I make on Facebook it's nothing but hating on anything but a coyote. Anyhow, I get your satire now!

I asked myself the same thing with his minimal hp to weight ratio, even with his 20 min 'weight redux' b4 getting onto the strip. I couldn't fathom his..superb results.

http://www.s197forum.com/threads/14...results-from-a-few-simple-mods.113854/page-67 Scroll down to post 669..which continues onto the next page.

His 5 krpm stall converter has a 2:1 stall tq ratio. When the light turns green, off the brakes and mash the gas....and his 1.5 krpm flashes up to 5 k rpm..asap. His 400 ft lbs of tq now feel like 800 ft lbs. The tq converter now is a tq multiplier. That's the secret with auto's, the aftermarket high rpm stall converter. His high (5 k rpm) tq converter is about the closest thing to a free lunch. After the way they explained it's operation, then it all made sense. He gets a massive tq hit right at launch time. Typ they size them for just below max tq, so on a NA coyote eng, the 5 krpm is optimized. He's only 300 something feet above sea level too, and with proper track prep, and cooler temps in Wash state, he manages to pull it all off, with lower DA's.

When he launches at 1.5 krpm, he has already pre-loaded the suspension., that's a big part of it.

I was talking to Pentalab!!

We're all just realistic around here. I'll be running a 3V until it inevitably turns inside out, then on to something else.
