Dyno for the 5.4
Pro dyno ran the dyno tune on it tonight and the results are
289.79 HP 366.55 TQ To the wheels and no corrections made I'll have to find a scanner so i can post it on here. it had 350TQ and more from 3K rpms and up till 5K rpms it still had 300TQ. The HP peaked the 289.79 at 4400 rpms but still had about 285HP to 5K rpms and at 5500 rpms I had 275 HP. I'm really happy with the results, especially being N/A and having TQ like a supercharged GT. I can't wait to see how it does with some cams and a better intake. And the TQ curve is soooo sweet!! now i see why i was spinning them in 3rd at the track on street tires.:punk: |
waittttt a second.. scan your dyno sheet? lol. this is pretty sweet. a guy i know has been thinking about doing a 5.4 in his stang. your numbers are NOT SAE corrected??? hmmm.
congrats on the ######s |

congrats on the ######s You can also ask Twin Tubo 330, he was there and another friend also. I didn't look at it at first, i was afraid it wouldn't be to good, but when he told me, i was like...damn thats sweet. |
that's kinda cool.. after my last dyno im kinda weird about SAE numbers. but when i tuned for cams it was under about perfect weather conditions and it didnt add much at all to the actual numbers if anything. :)

nice numbers!!!

It's dark and you can barley see my car. i would have taken my camcorder but i thought my camera would do fine, guess not. it's a short clip too. Also you can hear my crappy spintechs(not recommened) mufflers, man they suck. i'll still see about posting the dyno sheet, probably monday though. My printer/scanner is crapping out or something. |
mustang dyno or dynojet?
|
dang, did you dyno w/the lights off

congrats on the ######s[/QUOTE If you look at your dyno sheet that you posted were it says CP:SAE.. Mine says CP:STD |
god damn that is some insane torque!!

I talked to Dan at pro-dyno and he said it's STD and not SAE, he said if it was SAE, then i would probably add 10 more HP to make it close to 300Hp to the wheels.

that's easy enough to figure out. See if you can find the weather for the time that you did the dyno run (time and date). If the ambient air temp was higher than about 85deg, or barometric pressure was way way low and humidity very high, then you could actually be making a very differnt number.
SAE corrections are there to bring all the atmospheric factors to an even playing field. SAE allows hippies in a park in Boulder, CO on a 50deg day to turn in results that are actually relevant to the results that I might put down at 45 feet above sea level on a 100deg day. With std ratings you are usually pretty close to SAE if the temperature, pressure, humidity and altitude are all reasonable. Since you did your run at night, I'd call it about even unless it was really hot. Some people don't like SAE corrections because it makes them feel bad when they dyno on a cold day during high barometric pressure & low humidity. |

Also when i go to the track and everyone is like, oh a 97 non pi, heavy a$$ convertible...it's probably slow. After i run a kick ass time on my mickey thompsons, i'll tell them it's all tire. |
ok... with the standard correction you should be within 4% of your SAE numbers. At worst case you're making about 280/355 SAE. The humidity would have substantially impacted your output which both std and sae correct for. I would like to have seen the uncorrected numbers for comparison but I'd say you have a wickedly stout motor as it sits and ain't nobody gunna argue with 366lbs of axle snapping grunt. As soon as I see the chart I'll be able to give more insight.
I'll bet you made more than 300tq from 2000rpm onward which would make low rpm launches a lot easier. |

I sure am....maybe it will be done by then? |

Hey man thats awesome - how much that setup end up costing you?

Sorry to chime in late i'm on vacation soaking up the sun. But that dyno run was awesomely impressive and i can't wait to get my motor finished now. It only cost you 4k to have supercharged numbers minus a few ponies but just imagine what a supercharger will do for you. Go 5.4L :punk:

We plan on going to the track next Wed, can't wait to go!!! |

How much potential HP & tq can you get out of the 5.4 engines? Man I wish I could get that kind of torque out of my little 4.6 without doing crazy mods |
DAMN those are great numbers. Could you post a list of the specs? Compression? Ported heads? Cams? Just curious. Another awesome SC car.

how much power can you find was a question posed a moment ago. There's only limits based on how wild you wanna get and how attached you are to 2V heads. 4V heads lift the limits into orbit.
On a 2V if you can move the tq peak out far enough with cams and intake and major head porting (like to 4800rpm) you could see in excess of 350rwhp and as much as 425rwtq or more. More reasonable numbers are in the 300-315hp and 360-400tq and that requires really very little to acheive. As soon as Saleen drops some 262's in his ride he'll eclipse 300rwhp and probably shoot up to 380tq or better. With a supercharger/turbo on ported 2V heads you'll be in realistic territory up to 500-550rwhp, then you start needing more head flow or the boost pressure is just too high for streetability. Torque numbers up there are well over 600 and major drivetrain upgrades should be contemplated seriously. Add a little nitrous and they become unbelievably brutal motors. I found a guy on the corral that's running a setup much like mine will be so I PM'd him for some experience notes on what kind of NA power he was seeing at 10.5:1 compression with cams. We'll see. |

Good info guys! Thanks.

What do you guys think about that port-it-yourself head write up - im thinking about doing it, and that with a blower should be fairly nasty - like you all are saying.

2. :bash: You guys are missing the OBVIOUS point, the reason that a 5.4 makes so much more torque than a 4.6 is the EXACT SAME reason that my 351W makes more torque than a 302: same heads, same bore, LONGER STROKE! Torque is made in the crank stroke, ladies and gentlemen, it's that simple. Careful research and the right parts will do it everytime. Impressive numbers on the 5.4 dude! If I weren't so disillusioned by my first experience of stuffing a motor into a Mustang that it wasn't meant to have, I'd be hunting for a block myself. Try a longer rod next time for a better rod to stroke ratio, you'll see some sic numbers in RPM and torque then. |
the 5.4L already uses the longest rod I've ever come across in a production motor at 6.658". it's longer than any chebbie or ford big block rod.
The 2V heads are also largely responsible for the massive bias toward tq on the 5.4. With 4V heads the 5.4 tq output is less impressive in ratio to the hp production. It's actually a lot more similar to the 4.6 with somewhere in the 300hp/345tq which is basically ratio equal to the 240hp/280tq that you commonly find in 4.6 2v. the 2v heads limiting of hp production assures that the math of the matter will bias to the other side and boost tq to insane levels as tq and hp are numerically related to rpm. To learn more about predicting hp and tq based on each other, google it. |
