Stillen Header Dyno Numbers
OK guys, alot of you wanted me to take my car to a dyno so I did. The dyno was a dynojet unfortunatley the machine was not able to read torque correctly.
My best run was 224.76HP...the guy estimated that I was at about 230-235 lbs of torque judging by the readings that the machine was giving. This would put you manual guys up over 230HP.
My other two runs were 220.43 and 218.14. On the run for the 218 the guy forgot to turn the fan on.
Sorry I dont have a scanner...

MY mods are: GAB, Headers, Pulley, Straightpipe and 2.5 Catback exhaust to a Dynomax Superturbo muffler.
You guys can decide about the headers. A stock auto puts down about 198-200HP. So its 24hp between my mods. I would like my numbers to be a little higher. I will keep these headers until it is dyno proven that the hotshot ones are better.
On wed I am going to a mustang dyno to run again hopefully I can get some torque figures.

His way is cheaper with more power...meaning that the headers, once again, are not making the power Stillen claims...

How could they not measure torque? I thought torque is what was always measured and HP was calculated from that.
Anyway:
HP = (torque*RPM)/5252

put it this way with a intake and the stillens headers alone you should have 222 hp stillen said 20 hp and a intake gives you ten so even with 190 + 10 +20 your gains are not that great you didnt even add you cat back or underdrive pulley

I am very thankful for the org. Lots of guys wanted to be the 1st to get the headers, and I think after what *FOUR* dynos, its pretty simple to me. The $tillen headers suck, and ALL you guys should ask for refunds. You guys spent your hard earned $$, and installed them, and nothing. Sorry, i feel 4 you guys. I will NEVER, NEVER buy a $tillen product again. I hope you guys get taken care of. This is so disappointing....
g'luck on the refund process.

I'm waiting for the Stillen happy-police to chime in saying that they're aren't enough dynos, there is a problem with the equipment, the car isn't tuned right, etc. ANYONE who has been following Stillen's customers' comments for the last 5-8 years knows they are shady when it comes to marketing and service after the sale. I wonder if R&D costs were starting to exceed projected sales revenue so they cut things short and produced an untested design and made up some bogus dyno numbers.

Haha.. I feel really sorry for the buyers of this product, and even more sorry for all the people that have fervently backed Stillen, spouting nonsensical comments about peoples' cars not being tuned right, etc etc. Sucks to be you.

Together, they're "stealing" and "reeling" in the cash

I'm planning on dynoing mine again here in another week or so. I'll do it after I get the SES light to go off and after I install the Place Racing motor mounts. Hopefully I'll yeild better results than last time. Although my last dyno really shouldn't count since it was affected by the ses light being on and the ecu just being reset only 2 miles from the dyno.

I sympathize with those of you who have the headers. For the record I don't think they make much (if any) power, but none of you have done a proper dyno to prove it. This will make it very hard to get your money back.
Someone needs to dyno, put the headers on the next day and dyno again. After dynos are great, but if you don't have a recent before dyno you can't prove anything that someone else can't tear apart (especially not if you take them to court). You need to control all the variables and change only the one. So far no one has done that.

randonSE]I dunno man, from what i've heard with the kid i work with, he said hes got u beat, that hell tear you a new ******* any day... he said that he eats maximas... He said he will do all of this with his 2000 altima SE[/QUOTE]
and this has what to do with stillen headers?
you and your friend need to get off the crack.....

If you've seen the stock manifolds, you'd know that there is MUCH room for improvement. Problem is, Stillen's product isn't an improvement...
And as a post script, WILLSE and I changed his spark plugs at my house Friday evening...they looked NASTY! Talk about running too damn rich...

I'm starting to wonder if the Maxima's 15 hp advantage over the Altima is b/c of a better exhuast manifold design. So far we know that the Altima gains hp with aftermarket headers and the Maxima does not. Maybe this is why?

If Will doesn't see any change then hopefully next week or weekend we'll take my car in for a dyno again then swap the headers onto my car and go back to the dyno. If that doesn't answer our questions I don't know what will.

Sorry guys, the way I see it, these are very good numbers for just bolt ons and throws a monkey wrench into the "stillen headers don't work" situation. . Only auto dyno I see similiar to juice's is blubyu and we all know his car is a freak.
Juice also has 40k on his plugs and probably hasn't had any fuel injection service done recently either.

dont be dumb the headers were spose to give you 20 look at the specs online. Those numbers are not good for $1000 dollars for headers you should have way more hp then what you have they said 20 hp at the wheelsssssssss

what is wrong with everyone 224 is crap hp for what juice has spent
god 1000 headers that were spose to give 20 hp at the wheels alone
i mean come on
sorry juice you have a great number for hp but you should have way more. for what you have spent i jsut dont want you to get ripped off

We need to see the air fuel on these dynos to see what is going on if your car runs rich before the headers then you should get better gains with them if it runs lean then it shoud be less last dyno I did on my car it was running rich and my numbers were down ,so lets get some a/f on the dynos it will tell us more. By the way the guy with the 2000 alt that eats maximas send him my way I will give him indigestion

Also if you re-read all of my posts on this subject you will see that I have and still have serious reservations about these headers. Stillen's attitude alone is enough for me to not purchase any Stillen products.
A couple of items to note about juice's setup is that he didn't just not connect his mysterious black box, but he never even installed it. Also he is running a dynomax super turbo muffler which is not a straight through design. Don't know if these things make a difference but I just wanted to point them out.
Again, what numbers are people expecting from a stock auto with bolt ons. The best (realistic) dyno I've seen from a 5 speed Altima w/headers and all the normal bolt ons is 237 hp

Steve Millen donated a modded 200sx to my high school last year because according to what my auto teacher told me, Stillen would receive tax writeoffs for donating the vehicle instead of trashing it. I guess Stillen was trying to create some positive publicity for themselves seeing as they are a southern california company and Millen's son goes to another high school in Irvine. I should have swiped the keys to the prototype s/c 350z he rolled up in, see how it feels to have someone steelin your shieeet.
