Dyno results, ONLY mod Nameless Downpipe. (Yes, I know, no baseline....)
 

DISCLAIMER: NO Baseline before Donwpipe mod exists.


So, I wanted to do a Dyno baseline before getting a FI kit soon. Unfortunately, I had no time to remove the Nameless Downpipe High Flow Cat and Helmholtz. 2.5", so the rest of the car is completely stock but this is with Nameless DP/OP combo.
See below.

Numbers look good considering it is a Mustang Dyno but really, there is no baseline. Max numbers were 175 WHP, 142 WTQ. IMHO I'd say the Downpipe makes anything from 5-12 WHP and 5-10 WTQ. Numbers were SAE corrected. Thoughts, opinions?


I'm really sorry for the crappy Dyno image.....

Mustang dyno should read lower than Dynojet, since you dyno more than most people's baseline with Dynojet I am thinking this mod probably gave you roughly 15-18whp. That's impressive, but I am curious how much it helps in the midrange.

I guess that to look at how the mid range is affected, a good starting point would be their original Dyno sheet. (I agree with you that the numbers look impressive, but stated in the OP 5-12 WHP gains to be ultraconservative and erring on the lower side).

Is it with the High Flow Catalytic Converter or not?

Yes, High Flow Cat and Helmholtz. 2.5" OP updated.

that does it, my next mod is going to be Nameless Overpipe/frontpipe + highflow cat + helmozts

Very impressive figures, especially without a tune.
What a shame you can't do a baseline run then I could show MRT in Oz that exhaust mods can produce real power without a tune.

MRT
We have just about run out of brands and designs to test that will deliver real results.
So far we have seen exhaust that will generate "some" power over a stock zorst with stock ecu tune, but these gains are mainly due to removal of the two cats.

This is on stock air box? With oe filter??

You'll get at least those gains with a pump gas tune, and more like 25-30 whp with our e85 tune.

Just food for thought.. I totally understand wanting a full pipe set though. Bang for buck though, it's hard to touch the tune. Plus you get added features only software can provide (and updates!).

Yes, everything else in the car is bone stock.

(sound generator is removed and plugged, but that does not count as a mod).

I'll be getting this as my next piece to my exhaust, then the Nameless beast of a header. Thanks for the post David!

I think that's great then. +1 nameless is what i say, heck yah


I'm glad to finally see dyno results popping up

I want you to try an air filter drop in and tell me what happens, I have a drop in Perrin sitting for two weeks in a box in my garage. Im betting a trd or other drop in will help, too, I run one in wife's car on oe exhaust and she felt a difference.

Looks like she gonna get a helmholtz!

I am curious to know about filter. Wanna try it? I can send it to you at my expense, if you like it and you keep it I dunno slip me a $20 or buy me a few drinks. Lmk!


Congrats on the dyno results!

Looking at the results off the dynojet sheet... I made about the same with the motiv hfc and op. stock filter. I have a dyno sheet ill post when I get back home. After I got the tune it pulled 188hp. Oil temperatures were pretty high, considering I did a 4 hr drive to get it tuned...and I added a works drop in filter after that. I should be at about 190 now. Again ill post my dyno sheet later when I get home.

Was there a difference in sound with stock everything vs. the nameless downpipe w/ hemholtz?

Very good question!!!!
Missed that.:happy0180:

Just sounds more sporty and throaty....very clean sound.

I would love to be able to help, but next time I'll be able to make it to the Dyno will be less than two weeks with FI kit installed :( (I can ask @raul who has Nameless exhaust to see if he is interested). What filter are we talking about?? (Hoping for the Works!!!) Most probably he would do it in a Dynojet because that Mustang Dyno was expensive :mad0260:



Those are very good numbers! The only comment I would add is that Mustangs read lower than Dynojet's, but nonetheless, those are awesome numbers!


I really can't remember much how the car sounded stock as I went from Nameless full exhaust to removing the axleback and keeping the downpipe but I can say that it sounds louder inside the cabin. I believe outside the car its very similar to stock. All very nice type of sound, not annoying.

you cannot compare one dyno to another like that. Your best bet would be to compare another stock vehicle on the same dyno, less prone to error than one dyno to another.

Yes yes, I agree there is no baseline, all numbers are speculation. But a fact is Mustang dynos read lower than Dynojet Dynos, just the nature of the beast. I posted the picture with uncorrected and corrected numbers for weather conditions, so even though it is all speculation, we can get a ball park figure on where it is and Leemaster's guess is not far fetched BUT I wholeheartedly agree, there is no certainty based on this Dyno about exactly how much Nameless DP/OP gains, just ballpark figures.

Added more pics to OP

How does the nameless add so much more power than the motiv/invida/etc? From my understanding at the end of the day its the same diameter pipe with the same bends in the same places-am I wrong?

The nameless also replaces the overpipe and probably has a better cat (speculation of course).

Also the plot posted in post #3 from nameless is for the combo of the old axleback with the over / front pipe not just the Frontpipe alone with otherwise stock exhaust, or adding the over / front to the axleback. In other words if the stock catback is a bigger restriction that the front pipe, you would see a bigger gain from the front pipe AFTER replacing the catback than before replacing it.

I am running the catted, helmholtz, over/front pipe right now with otherwise stock exhaust. I am not going to bother going to the dyno again until I add the axleback. The sound is a little different, a bit more aggressive. But in all honesty, after the first few minutes of a cold start you would be VERY hard pressed to tell mine from stock.

So, it is louder during cold start, but once the idle kicks back down you can't tell a difference due to the stock catback.

Nameless OP/DP has different bends and makes the OP/DP into one piece. The point of this thread was not to advertise or showcase the Nameless DP/OP combo. My only intent was to get a baseline before getting a turbo. I was not going to bother getting the car up, raising the engine, etc. just to get a compelte stock baseline, so I only left that installed in the car and Dynoed it. It just so happens that the Dyno numbers came in that high. But like I made very clear in the OP, all numbers are just speculation because I dont have a real baseline number. Either way, numbers look impressive given it was a mustang Dyno but ALL speculation, nothing else.



Edit: Mad_sb was referring to the Nameles Dyno plot, not mine.

My car was with ONLY DP/OP everything else in the car was stock :D

I think I remember reading somewhere from nameless that there isn't a power difference between the downpipe and downpipe overpipe combo. I also remember them saying the cat they use flows the same as an open 2.5" pipe and is rated for a 500 hp engine. So if there is a difference it may be that.

Yeah man, not your plot from the original post, sorry for the confusion. The nameless plot from post #3 is the one i was talking about. :thumbsup: I edited my post for clarity, the plot from post #3 is for the combo of axleback and front / over pipe according to the nameless website.

Ohhh yes yes!! Nameless plot is with OP/DP AND Axleback :happy0180:

Good numbers, but wait till you have boosted numbers lol. Your going to beyond happy.

I have a baseline with ONLY the Nameless offset axleback. I just installed the over/downpipe with HFC and Helmholtz; I'll will go back to the EXACT dyno I got my baseline done on and provide the forum with those results.

Sound? Good god it's awesome.

wow! crazy plot.

I just dyno mine yesterday on a Mustang and made 139whp witha full headerback SRT

soo sad :(

I was looking at the monitor STUNNED. Such high numbers.

I was considering a full na build but afer my dyno session I am too angry at what I see. Turbo will be in y future as well.

Looki g forward to seeing ur turbo dyno so I ca know what to aim for

@Mr.Jay, my car made 174whp on a dynojet with just an SRT. Mustang dynos can be modified to read like anything else with a click of a button, practically. I think you just went to a low calibrated one.

Likewise, sportsguys' dyno apparently reads like a dynojet. Good numbers, though!

Heres my thread...

Motiv OP, Motiv HFC with stock filter.

Shameless bump?? :D

just posted my dyno sheet

JK my friend :happy0180:.

Yours is DP + tune + everything else stock if I read right?

Yeah just spoke with them again and turns out their dyno reads 25-30% lower which makes me feel better but damn it was hard to take when I saw the plot.

Next time in goin dynapack lol want to see some solid numbers

haha with a dynapack, you'll hit 200whp just by looking at the car ;)

So I wonder if there is any difference in power output of yours with the cat and mine without? I've put in their catless HH over/front pipe, their axle back, and a K&N drop in, I wonder what kind of numbers my car is at?

those are good numbers but not all mustangs read low. some owners adjust the roller weights so that they display more alongs the dynojets numbers. I always kept my Mustang unadjusted and cars that make 156-158 on my Mustang lay down 183-185hp on other local dyno jets. All my tunes are done on a Mustang but i always take them to my friends dynojet to give apples/apples comparison. i know you couldnt get a baseline but it would have been ideal. now hopefully some realize you cant always get a baseline on your car because time and availability didnt permit.
