So what do we know so far???

-There was a difference of 14 whp and 20 wtq between the worst and best header tested.

-The car they tested is almost identical to the my R in terms of modifications. The test car had its power steering belt removed and a Comptech Icebox. My only mods is timing has been set to 18BTDC and the Comptech Icebox. I dynoed my car on a Mustang Dyno (the dyno used for the header test) and the results were
HP: 154.4
TQ: 103.1

-Let's assume two things.
1.) The worst header did not affect the numbers at all.
2.) The test car dynoed in with similar numbers that I have for my car.

-By adding the best performing header, my numbers would jump up to
HP: 168.4
TQ: 123.1

-Keep in mind that numbers from a Mustang Dyno are significantly lower than that of a Dynojet. I don't know what the exact correction factor is but I've been told it's as high as 15%. So let's be modest and put it at 10%. Here would be a guestimate of the numbers corrected for Dynojet.
HP: 185.24
TQ: 135.41

I don't know about the rest of you but that's some nice numbers from just an I/H/E setup. I know there's a lot of assumptions in my analysis but I think it's not too far fetched.

Another part of my dream was the results of the #1,2,3 finishers.
#1 was Jun for some reason. Maybe it's because I tend to root for underdogs.
#2 was the SMSP header.
#3 was the Spoon.
There's no logic to it. It was just a dream.

 

hehe I don't know what to say about that..

I'm waiting for the results as well, just because a friend wants me to do some exhaust work on his car..

 

George, you said " I " was thinking about the test way to much. This guy has it bad

Yeah, that's why the Topic title says that "It's Sad"

 

if your dreaming about headers....my advice would be to go outside and start talking to some chicks..

lol.

j/k pal.

Jeff

 

...or turn on sCinemax

 

None of the info is guarded, We just agreed to release everything at one time because peak #s don't tell the whole story. But the highest wheel HP was I think 190 with highest wheel torque in the area of 138 pd-ft. I don't recall the exact #s because it was a long day with alot of fumes. Theres alittle more of a teaser.

Don't make me bust out the mama jokes!

 

Mmmm, I miss skinamax ......... (we decided on no pay channels when my wife finally got cable).

 

I'd like to mention that the car just seemed to be strong as hell stock. Don't quote me on this, but I think the baseline run yielded around 170whp. This seems too damn high, but we ran the baseline like 5 times with similar results. Maybe it was just a strong car. Or maybe it was canuckr's spoon oil cap. Either way, I'm jealous.

 

We were going to do a tribute to RStoR's molestation of headers but it was just too long of a day.

Chad, hurry up these boys are starting to spring leaks.

BTW, the dyno shop temperature stayed between 62-64 degrees all day long with the bar pres hanging around 30.4-30.45 from what I remember.

The baseline run was done using the stock manifold and cat back but with a 2-1/4" Carsound cat, I can't confirm sackdz's numbers. It's probably due to the fumes as Dropspeed said or lack of sleep.

My guess is that the SMSP and the HyTech-modded Mugen did the best.

Spoon, Type One and JUN probably did bunk compared to the others.


I guess we'll see....

 

Almost forgot to Thank MIKE K for shipping the ness parts to do the tune-up on the car

Mattj

 

My Money is on Spoon and Toda

 

The NASCAR tech show that has the old racer and the young woman had a short segment on exhaust. The header that they showed during part of it was a long primary short secondary 4-2-1. Couldn't tell if the primary's were stepped, and there were no AR cones. I think those Dr. Gas like Boom Tubes are pretty cool - I'd like to look those over at closer range.

Scott, who know's that John would never sell him a header now.....

 

That's some crazy numbers for a Mustang Dyno! Those numbers are unimagineable even on a Dynojet with just I/H/E. If you guys need help plotting that stuff, I'll be glad to help! These leaks are killing me.

Thank you Mike K for the tune-up parts, it helped. My car baselined at 176@8000. I think the Spoon oil cap really helped get me that number, sorry Ed.

Hitech all the way

 

The guy who told us we could use his HyTech header never came through and the same thing happened with the guy who told us we could use his car. We had a car thanks to canuckr

We couldn't get a HyTech header to test but we did have a MuTech or was it a Hygen? I guess it's a MuTech since it starts out as a Mugen from the head.

 

That sucks I am pretty sure the Hytech would have won. Would be interesting to see what the MuTech did.

 

178@8000 with nothing more than P/S belt removed and Comptech Icebox on a Mustang Dyno?! That's amazing! Makes me jealous actually. You suck! jk

 

Holy ****!

190whp, 138 lb/ft? I don't care if that's just a spike or something... That's ******* incredible for i/h/e on itr! (remember stock is 155-170)

 

I wouldn't go and try to compare these numbers with your own graphs. Everyone should be looking at these numbers with respect to the headers tested on this car on Saturday and only that.

I think we'll get to see a HP and torque data sheet of values with the first column showing an rpm range from maybe 3000-8200 (?) in increments of 100 or 200 rpms, then a column for each header. Then you'll be able to calculate the difference in torque and HP between any of the headers at any rpm, versus trying to read a graph to +/- 1 HP or lb-ft.

 

So when are we going to see the results, I can't wait!!

 

Does anyone (chad) know, once the information is made public, if the data are also going to be made available for us to download in excel? I think after he gets all the data inputed and generates graphs to be posted along with his write-up, it would be nice if we also had the option to download the book (spreadsheets) for the various headers. This would give us the opportunity to overlay, or plot various headers against the others.......The data speak for themselves and allows others to draw their own conclusions.
