My Mustang Dyno Numbers
 

I finally got a Mustang Dyno tune done yesterday and the temperature was 73 outside. I have had my car for 20 months and less than 9,100 miles on the odometer. I do not drive the car hard and I have went close to red line maybe a couple of times since owning it. To make a long story short, the tuner said I need to drive the car like I stole it in order to get better whp numbers. I'm not really worried about what kind of numbers I can produce, but more into the sound. The turner was in fourth when the tune was getting done. The turner was also able to go 160mph in 5th and never touched 6th and the limiter on my car is 179 mph. Everything on my signature below was what was on the car for the tune. Please see attachment for Mustang Dyno numbers and the link below of my car on the dyno.

Sound of 370z Nismo on Mustang Dyno With Mods - YouTube

did i read that right, 274 HP. seems low

Mustangs are known as the "heartbreaker" IMO these are not bad #s for the type of dyno.

I got 310 whp after I has a FI exhaust and uprev tune

I didn't know what to expect for whp numbers and the Mustang Dyno numbers are supposedly the lowest compared to Dyno Jet and other dyno's. In the end it is not about the whp number, but more about how the tune is actually done/setup.

There were two other Nismo's with almost the same mods and they produced a lot more whp. One of the Nismo's produced in the low to mid 290's and the other Nismo was at 301 whp. These two Nismo's had an easy 30-40k plus more miles on them and have been driven how they were supposed to be driven. I do agree with what the tuner said about driving the car more and driving it hard (not dogging the sh*t out of it) to break the car in.

Oh I just added a video clip of my car on the dyno (my first post), so you will hear how the Meisterschaft exhaust sounds along with the other mods that are on my car (please see sig for mods).

Damn OP!! I just love how he gunned it and man can your Z Scream! :tup: what's important is the curve am I right? Man I still can't get over the sound wayched it like 3 times already xD

VERY true. Also, dyno #s are somewhat useless. It is more about what you gained!

LOL..... I appreciate it. The vehicle was already warmed up & this was his third go at it. The tuner loved the sound of the exhaust & everyone there was like WTF is this & what mods do you have.

The FI RHFC was installed two Fri's ago, the Stillen Gen 3 was installed last Fri & the M370 Intake Manifold was installed that day of the tune/dyno. I'm not an expert on dyno's. I would think if you have a good solid positive curve, then that is good.

This is what you are going to feel more than 95% if you DD the car.

Hmmmmm.............. My Ford Fusion is my DD, but the Nismo might have to be driven a lot more now.

Your Car is loud as hell. I love the sound but too loud for my taste. I need to be able to drive home w/o waking the neighbors.

Mind if I post my Dyno in this thread? It will give good comparison. I only have K&N short rams. Everything is stock. My car was Dyno about 1hr after his.

As for the low ##, everyone at J said that everyone was running low yesterday.

Thnxs..... I'm not going to drive down the street at 7k plus RPM's......lol. I keep the RMP's less than 3k.

You can post your dyno on this thread. I thought about going back to JTran this week and getting another dyno. The reason it will be colder outside and my car will have a couple hundred more miles put on with the mods instead of going in cold.

You may not have given the ecu enough time to learn the mods. I'll bet you'll pick up a few more hp as time goes on.

If you want a more comparable number, go find a Dynojet. They're more consistant. I used Powerfab for my baseline. Mustangs have too many variables in the way they're set up to be able to compare numbers with other vehicles.

I agree about the ECU not learning the mods and I have heard that you want to put at least a couple hundred miles on, so that the ECU can pick them up before you dyno the car.

Dynojet supposedly has better (higher) dyno numbers, but it’s all relative. I wouldn’t bank on the actual dyno numbers because not every shop is going to have their dyno’s set up correctly/perfectly. I also wouldn’t recommend that an individual puts all their eggs into one basket and base their whp numbers on the Mustang numbers, or just on one dyno read out. Mustang read outs can be a pretty good kick in the d**k on what you think it should be and what the dyno says it is.

I have heard from countless people that a car losses 15-20% of its total hp before accounting for actual whp. As I stated earlier when I had my dyno done it was 73 outside and several hours later it was in the low 60’s. I guarantee you that I might have been able to squeeze out a max of 10 extra whp (maybe), but I need my ECU to become more familiar with the new mods.

Your car sounded great! The snarl under acceleration sounds awesome! Then the BBBRRRAAAAPPP on down shifts are hawt.

JTran's Dyno is set to read low on purpose.

The reason I suggested a dynojet is that there's less setup, so numbers are more comparable to other cars. Mustangs can be set up however you want them to read, so its harder to compare two vehicles on different mustang dynos than dynojets.

A lot of people were like WTF is that and what do you have. The exhaust is definitely an EFFEN screamer and a head turner. I love the acceleration and especially the deceleration while downshifting noise. I still get a big smile on my face when I get up to 4-5k RPM’s, but I’m going to start opening her all the way and just let her EFFEN scream like she is meant to do.

I’m not disappointed by the numbers and I wasn’t holding my breath for the car to be 400 whp. The dyno numbers are cool and everything, but it is all what the tuner can do. I will go a couple more times to JTran, so I can have a more accurate number for my cold weather map and I want a map for when it is EFFEN Texas balls hot outside.

If I was to do a dyno on a DynoJet, I would think my whp would be in the range of 320-340 whp (probably 330 whp give or take 1-2whp). Realistically the whp might be 325 whp give or take 1-2 whp. This is just pure speculation on the whp, but the key is for the ECU to get the mods down and for me to drive the car like I stole it.

Ohh yeah, your Meisterchaft sounded the best off all the cars that I watched get dyno. IT was defanatly the BOSS!!! Just too loud.. in a good and bad way. Jtranz dyno is finiky i guess. My bros 07 Stang Shelby read only 257 whp and like 280 tq. He does have allseason tires and they are 1 size smaller than what there are suppose to be but man!! It's a Shelby v8. I still would not try and beat him on the highway going at 60mph. His car slams you into the seat when he gasses.

IT was definatly a cool event. After we went home, both my bro and I started reading on supercharging and turbo.

As stated above, I'm completely stock other than K&N short rams.

LOL..... Thnxs & I appreciate it. The exhaust is definitely a holly effen mother. It can get extremely loud. Those numbers are very low for your bros Shelby. The Shelby is no slouch on the road & he would more than likely spank 95% of the people there on the road. I have no idea what I actually ran that evening when everone was there. Mustang Dyno's are heart breaker (aka kick in the d**k) number generator. What were actual numbers? It looks like you produce 256 whp & 215 lbs of torque.

Need to look more...so a tunes only good for 14hp and 9tq?

258 whp/215tq

Maybe....if not more depending on what you have on your car. A tune will help give you constant power throughout the RPM band & pickup the ponies you lost when adding multiple mods.


Nice......very nice & not bad @ all for only having one mod.

Have F.I. ...
 

I've got F.I., non resonated CBE, must admit, the vid is sick.., great windup! Hope you have a Great driving experience...since having the F.I., I've got a new car. I'm like you, don't really care about hp, car's got more that I'll ever drive too, just like Sound!! MHLivesay :happydance:

Not to mention better throttle response and the ability to adjust the fan cycle.

Sure, you may only gain 10-15whp at the peak, but the torque gains at low rpm are more than double that.

:iagree: FO SHO playa. You get better gas mileage too, but I'm all about the ECU picking up the mods & the wild man behind the wheel.....hehehehe. Don't go to some douche bag joker who doesn't know jack squait about tuning the vehicle. Getting a tune from the right shop/guy is a 110% win win. JTran has it on lock down on moding & tuning a vehicle.

Not from his chart from what I'm seeing. Biggest gains were only up top for HP and the 9tq was mid range. I guess I'll have to see. As of now my logs are damn near perfect. Only a little leaner and a few more degrees of timing I could use. Just hoped its more.

A buddy of mine picked up 20ft/lbs under 4500 rpm.

Won't be bad, that's almost 250tq then down there.

:iagree: At that time I was getting 6 whp & 9 lbs of torque. I kind of feel like I'm driving my 2002 Acura RSX Type S that I had, when I'm @ higher RPM's in my Nismo. In the Nismo I feel a boost once I go past 6k RPM's & in the RSX Type S the Vtec kicked in @ 5,500 plus RPM's. The Stillen Gen 3's are known to produce higher numbers @ higher RPM's.

I know for a fact this car can throw down better numbers than that, but it's all about getting the ECU familiar with the mods. I've been getting on her & opening her up, but I'm thinking about doing this a little more aggressively now. I'm thinking possibly of doing some quick sprints from 0-120 mph & 60-120 mph.

Holly smokes Batman.....that is pretty effen sweet. What mods does he have on his ride & is it a 370Z?

It's a bolt ons and tune g37, so pretty much the same car.

Damn.... I need to move quickly on having the numbers increase.....hehehehe. Overall I'm impressed & I love the sounds that is produced from the car, but things could be a little but better. In the end I need to be happy with what I have & not what I do not have.

Not sure what you're talking about but getting on a car does nothing. Nothing's going to change. The tune is the tune, period. During a motors break in, getting on it is great to properly seat the rings so the motor holds higher compression but this is done within the first 20 miles. You've missed that time frame by now.

Numbers aren't going to increase. I ******* hate mustangs. Someone's clearly ****** up the settings to make it read that low. Find a real dyno. Even then it's just numbers which no one cares about. The before and afters whats important and your trap speed at the drag strip. That's all.

This. Stop getting so caught up with #s. Trap speeds are a true way to tell how much power the cars making

That's for sure and numbers are just a sociological thing I guess. The shop mostly used the Mustang Dyno for Subaru's. I eventually need to hit up a Dynojet and see what my numbers are.

Your the second person that has mentioned trap speeds. This might be a silly question, but what exactly is trap speeds?

MacLean, don't u sleep man?? it's late!

Trap speed? like 1/4 mile times?

Not time. 1/4 time has nothing to do with it. Thats based off of a good start, great shifts, proper setup etc. Your trap is all about power.

Its at the 1/4 mile when you cross the finish line. See HP is fake. It's not real. It's just a calculation of TQ which is real and measurable but all dyno's can be messed with and read wrong. No matter how bad your 60 foot is at the drag strip, you'll still trap a certain speed at the end of the run within a mile per hour or two. Since we know the distance, we know your trap speed, and we need to know your cars weight; based off of that we will know your true HP since there's no way you could reach that mph within a 1/4 mile weighing 3xxx unless you have xxxHP. A dyno doesn't take into effect drag coefficient etc so running at the track gives you the best/true result of your power.
