DYNO'd my car today.

Best run was 378hp/328tq ... comes out to about 444hp/385tq assuming 15% drivetrain loss. I'm honestly a little disappointed in the results, I was expecting to be much closer to 400 at the wheels. The shop seemed to think that in better weather (it's hot as hell today) I would be, but I seem off by a long shot to just blame it on the weather.

I was running my datalogger (livelink with my SCT X3) and will be sending the data off to Bama to see if they think everything looks OK or if adjustments need to be made.

Re: DYNO'd my car today.

They didn't put it on the sheet (not sure why). I had a datalogger running and can email you the run file if you can open it (need SCT livelink).

Re: DYNO'd my car today.

You have a Boss intake and only redlining at 7200ish? That one issue. Next issue is Bama tune, then followed by you need some headers with a x pipe.

Have them take your rpms out to 7800. You will see more gains. The Boss is still making power out that far.

I have seen some stock 5.0's with those numbers, there seems to be something wrong. I would expect slightly over 400 to the wheel with those mods.

I understand that every dyno is different, but these results are pretty low. I mean I'm putting out stock numbers with some significant mods and a tune!

I assume this was done in 5th (1:1 gear on this car). This is a very reputable shop that has done tons of mustangs and some 5.0s already. I didn't even think to question it.

The heart shouldn't play a huge factor in lower numbers. What was the ECT? Engine Core temp that will be a good indicator if the heat was factor or not.

Re: DYNO'd my car today.

Just From seeing a few dyno sheets on cars with similar mods I would say that's low too. Is that a custom tune or a canned tune?

I would find out what gear for sure..I know a few shops that still think that you should dyno them in 4th.

As mentioned also I would get a updated tune form BAMA or get a new tune form some one else.

You have a PM..

AM has a video with their claim.

AM claims to get just over 400 with their Boss intake. You might want to give those guys a call, plus as everyone else is saying BAMA for tunes, AM works with the BAMA guys.

You have any pics of your engine, I would like to see the Boss intake on your engine. I'm debating it.

I've already sent them the dyno sheet and datalog. The guy I talked to on the phone (Dan) seemed shocked that I was putting down such low numbers with those mods and said he will make sure it gets looked in to.


This is from kinds far away ... I'll look around for a better pic.

EDIT: Here are some better ones.

Re: DYNO'd my car today.

I would say that its not that low ... I mean I've seen stock 5.0's comin in around 360
Bad air could have a lot to do with it ?
My Buddy's Boss only dyno's in at 385 stock , and he dyno tuned it and could only get it up to 401 ...
so your not that far off, every car is different

I would be really disappionted if I had a boss and it dynoed at 385. When the average manual 5.0 is 370-375. Then only to get to 401 with a dyno tune. I made 409whp with cold air, axle back mufflers, email tune from BBR.

I agree the OP's numbers are low. I am thinking it is in the tune/wrong gear and heat combined.

I ran 11.88@106 with just tune, cold air. with a DA of 350. Low trap cause I lost 5th gear. Best trap of night was on a 11.90@118.

Friend ran 11.88@114 with his same night with just tune.

Another friend with an auto went 11.3 with tune and stall. And less whp then all us.

The boss has not proved to be the best car for drag racing yet. Which is fine since it wasn't built for that purpose anyway.


My last time to track I ran 11.80@119 with a DA of 3200. Correct it was 11.3@122. that was with 450whp before my dyno tune. On a BBR email tune that same night where had my rpms set at 7300 I managed best of 12.1@115. We put new tune in it that night my buddy wrote right then. And ran .3 faster with a 7700rpm red line. Dynoed the car with both the BBR and the one buddy wrote on the spot. The BBR was 8whp/10wtq lower. Plus I had some idle issues with the BBR tune.

Awesome...I don't recall if you said it or not, but did you do the install yourself? If so how difficult did you think it was?

I did it myself. It was easy, except for some bad advice I got from the Internet.

ALL NICE ET's
true it is a handling car , but to run a high 11 , bone stock , with less than a 1,000 miles on the clock ,that's pretty freakin' fast !!! I've driven the new GT , And John's BOSS ,and there's no comparison believe me , the difference is night and day .. you would be impressed if you drove one I'm telling you
of coarse my car's a dinosaur compared to the new Iron so I don't have a lot to go by , lol
na, actually I do ,thanks to my friends who all earn more $$$$ than me I get to drive all of these great cars

I could ahve told you stock air box don't fit...And as far as bolt fuel rails on then bolting the Boss down. That is what we did. We also have universal joints and etc etc. With fuel issue we bleed it all out just cause my buddy said they will spray. Said he seen to many times.

I have road in a Boss. But it was hard to compare to my car since when I got to ride in it mine was full bolt ons already.


I do think to many people are worried about what the Boss does in a straight line since it was not met for that. It was met to be a high revving track fighting machine. Taking corners as fast as it can. Then two 1/4 mile and corner carvers don't really go together.

My buddy has a 2V that can spank the **** out me in the turns. It is a pure American Iron Racing Car set up. But he took it to the drag strips and was slow as ****.

Re: DYNO'd my car today.

Well, I just got an email from the shop. It turns out the dyno guy accidentally used 4th gear for the pulls (old habits die hard I suppose) and they will be giving me another set of pulls. I'll post back here once I have the results.

Yeah, unfortunately nobody had confirmed or denied that before I tried. I made it "fit" but it wasn't optimal by any means. I don't think you're really supposed to use flexible/universal joints when using a torque wrench. I don't trust that the readings are accurate, and these bolts are pretty darn delicate. As easy as it was to put the fuel rail on with the Boss Intake Manifold in place, I wouldn't recommend that you do it another way... there just isn't a worthwhile trade-off.

^ this +1million. It's not completely terrible for drag though, the top end power does shave a bit off the ETs, more than you lose in low end torque for sure. The right tune smooths out the curve a lot from stock too.

I hated to even ask them ... it's almost an insulting question to ask a reputable shop but I'm glad I did. Like asking a doctor to wash his hands I suppose

I think I might see more. Bama tweaked my tune and it felt like it was pulling a bit stronger yesterday when I took it for a spin to capture some new data.

I had a shop tell me it didn't matter what I went in 4th or 5th. He said he dyno my car to prove it. We did. My car made about 18whp less in 4th then it did in 5th. And this was the guy was suppose to know everything.his claim)He has a LS1 Fbody that goes high 9's so everyone thinks he is great. The car is gutted its his shop car but still 9's all motor is nice. It goes low 9's on spray. I have seen it my self. But rumor is he does great on his and people he likes but regular customers he does just ok. I didn't let him touch it besides giving some base numbers and just to prove him wrong.

That good you got a tune update.

I still say you need to take advantage of the Boss. And only going to 7300rpms is not taking advantage of it. With it the car loves to breath and rev to the moon. 7800....THat will be the key.

Awesome I knew the numbers weren't making sense!
Let us know how it goes.
Nice job on the install by the way

It goes low 9's on spray. I have seen it my self. But rumor is he does great on his and people he likes but regular customers he does just ok. I didn't let him touch it besides giving some base numbers and just to prove him wrong.
I don't know that I would have even let him touch it at that point ...

Agreed, the SOTP dyno felt a difference in the adjusted tune as well, so I'm anxious to see what kind of numbers Im putting down.

I agree that there is more power to be made past 7300 ... I keep hitting the redline hard because it's not dropping off at all. I just don't know that the stock rods have what it takes to hold together at 7500+ RPM. I've heard that they are forged but the pistons aren't. Not sure if anyone can confirm that or not. Couldn't I also have issues with the valve springs at that high of RPM?

IN the 5.0 the rods or pistons are not forged. The boss has forged pistons not rods. The rods are a hair thicker though.

Also there is plenty of people taking the 5.0 to 7800rpms with no issues. Livernois/Evolution/Woodbinemotorsports/Revplution Automotive/Me/ I have know about least 6 others on modular ford doing as well. None of us have had issues with it.

The article linked above states that the rods in the coyote are forged ... therefore the ones in the Boss would likely be forged as well.

I'm honestly not too sure what the forged pistons buy you without going FI ... unless they expected a lot of Boss owners to do so (or are planning a FI Boss or a power pack for it). I'm not an engine expert, just know enough to be dangerous so I may be a bit off base here.
