Nameless Performance Equal Length Stepped Header

[wparsons]

^^ That chart shows the lowest gains of any of the nameless charts I've seen, compare some of the better ones as well.

[Mars2]

Is their any other INDEPENDANT chart's available?
I only find other's that are from nameless

A pull on a dynojet for me today (Toronto, Canada) will be very far off someone in Colorado or Florida or etc doing a pull on a dynojet at the exact same time.

It's exactly what I do I look at percentage gain from base line. If you read my first post I even corrected when I replot according to different baseline to compare.

the two other independant nameless dyno that I found are in the same range as the first one that I post.
take the time to plot the FT86 speedfactory uel header dyno on one of them and you will see why I have this question.

this one is tuned:

@Mars2 I'm with you on the FT86 speedfactory header. I think it wins hands down. That header has perfect fitment, a high flow cat, and is cheaper. No one has had issues with it and everyone seems very pleased with its quality and performance.

Still waiting on my headers...however...

Ordered the OFT last night. I hope this comes before the headers!

I'm not knocking the FT86SF header in any way, but if you really want to compare the two headers you should looking at area under the curve where it matters.

Re-scale the charts so the baselines are as close as possible in shape, actual numbers aren't so important. Then calculate area under the curve for all four curves (both baselines and both afters) then calculate the deltas between before/after on each header/baseline. Then plot the two deltas as independent curves to see how much over stock each header is giving at which RPM points.

If you want to see a similar comparison, check out the SC comparison thread CSG Mike posted.

[Mars2]

I have plot both of them from 2000 rpm to 7000 rpm each 500 rpm scaling according to base line.
And area under curve from 4200 to 6000 rpm is pretty similar with a couple more HP for Nameless wich I don't think you will feel in real world driving.
but on bottom end and top end the nameless is just way lower.

I have the number in increment of 500 rpm corrected compare to base line for both in a excell sheet.

[wparsons]

Are you comparing area under the curve for both afters, or are you comparing the increase in area under the curve for each?

Just look at the nameless untuned plot, there's a wide uniform increase from ~3800 right up to ~6800. On the FT86Factory plot there's some increase down low, then some increase up top, but not a uniform increase across that whole RPM band.

Also look at the baselines, there area few places where the nameless baseline is well below the FT86SF baseline, and a couple places where it is slightly above.

In the attached images I've scaled the nameless dyno to fit the scale of the FT86SF dyno, then traced over all the lines to make them easier to see while overlayed.

I'm only intrest in comparison Tune VS tune.
Personaly I will never left my car untuned with a header.

Untill now look like the FT86 respond better than nameless to tune.
Moto east could only bring a litle more torque at each rpm on nameless so their for the power curve is of tuned nameless is very close to untuned.

But maybe in futur with more of those tuned I will be completly wrong.
But for today comparing both tuned on independant dyno. the result's speak for the FT86 .
I was very exiting to buy a nameless in fact almost ordered one and then did this comparison just to be sure of what I'm gone a buy and after that I changed my mind for FT86. Because similar in mid range ( I'm not fighting for 3 or 5 hp more) tuned better low and top end.Nicer sound f,or me have a cat, it's lighter and cheaper.

I just did that post to see if somebody prove me wrong and show me a dyno with a tune that give really better number than the otheron here. Something that you can feel when driving in real world I mean something like 10hp more every wear from 4000 to 6500 would make me change my mind.

[Mars2]

Thank's for arguing with me it made my decision even more strong. I will not post anymore on that as I'm a bit out of the subject.
I appreciate you try to convince me

[wparsons]

Also keep in mind the Nameless dyno was on a mustang, in different conditions, etc. What's important is the relative gain, not the overall numbers. If you look at two charts, the nameless gains way more over the baseline for a way bigger RPM range.

If the difference is enough to justify the cost difference and no cat is entirely up to you, but forgetting both of those, it definitely makes better power.

I'll gladly do the same thing for tuned vs tuned if someone finds the dynos for me.
