well, your wallet will be about 1k lighter, but that's about it. I'm guessing 185 tops. No more than 120 to the wheels. There are better headers, cheaper (better made) exhausts, better performing intakes, and I'm not 100% sold on the chips avaiable, as I've never seen a definitive dyno of them. (I've also been out of the loop for a bit, so they may have some documentation by now)
In other words... if you want to make your car faster at the track, or auto X, I'd say tires, or suspension first. Imho.

Well, I have tires and the majority of the above, but I just ordered a Stromung Axleback to replace my ghetto fabulous straightpipe.

hey joefocker20! what kind of strait pipe did you have? was it a dynomax,flowmaster,magnaflow or another domestic pipe? if so was it mean sounding? I was debating the price for v8ish sound
100 domestic vs 500 plus subie specialist brands. I only want sound not performance.

it really depnds on the brand of dyno. Different methods of dyning can lead to different results. That was a low estimate. I believe based on my projection a stock 2.5 00-01 motor puts about 105 to the wheels. Though I could be wrong.

I saw a dyno report that said the stock 2.5RS put down a measly 99 hp to the wheels. Too bad the AWD comes with a price!

all this time i have been led to believe that we make 122whp. this is calculating roughly a 25% drivetrain loss. oh well...

ProECM dyno'd an extra 4 hp across the board, GanzFlow 9hp, Stromung dyno'd 5hp in SCC magazine, Borla headers dyno'd 6 hp

Can't say you can add the numbers and be correct, but thats an extra 24hp or 189 crank if you do that (if you didn't live 6000 feet up).

BTW: your no muffler tail section was too loud last time I heard it

Lol, is it really that loud? Well, I now live at sea level until I find a job outside the ghetto state of NJ and move back to Colorado.. I would gladly turbocharge the piss out of my car to make up for the altitude difference than live here

Those numbers are off. The MRT header back system dyno'd for an extra 14Hp to the wheels and I'm not sure how much of a gain the Cobb intake has.

What I'm trying to say is that my friend has a Ganz intake, Borla headers, STI cat back, Lightened flywheel, and Act full clutch. While my car only has a Cobb intake, MRT header back system with a Stromung can. We are dead even in 1st through 3rd gear but begin to steadly gain on him in 4th gear, and I still have the anchor weight of a Flywheel.

I think it has to do with driving ability personally.

I've thrown out a 28 hp estimate on your setup in the past (you've got the hi-flow cat). Sounds like I'm still right

I'm talking about a rolling start, not a drag race.


Oh, I do have the high flow cat, (the lack there of is probably what held my friend back)

It has to do with driving, when do you shift? When does he shift?
Are you both in 2nd during the rolling start?

How do you dyno crank HP?

Get a Cobb intake, you can really feel the difference.

Nobody dyno'd crank. I added the theoretical 24 additional whp to the theoretical 165 crank hp subaru advertizes.

Interestingly, some dyno places print dyno curves with a correction for estimated drivetrain losses, as crank hp, like it was kinda defined "constant" like pi

Well, you did say dyno'd, and you don't dyno crank HP. You can't just take a guess about how many horsepower a mod gives you. And you can't back it up by saying it was dyno'd.

What's your point

My post is pretty clear to me. But to clarify, the number's were wheel dyno results where I said "dyno'd", but the intake #'s don't say dyno'd because it was a road dyno that calculates that mythical crank HP number and not wheel hp. That's the only reason why the 24 wheel hp is "mythical".

Uh, what?

He gave dyno at the wheels estimates (which are not true) and added it to crank hp. How is that correct?

You can't just pull out hp estimates from thin air, add them up, and come out with a hp. They work differently with eachother, and are very dependant on certain things for how well they work.

And no, don't cite your exaggerated butt-dyno as proof.

I said above, "ProECM dyno'd an extra 4 hp across the board, GanzFlow 9hp, Stromung dyno'd 5hp in SCC magazine, Borla headers dyno'd 6 hp ... But to clarify, the number's were wheel dyno results where I said "dyno'd", but the intake #'s don't say dyno'd because it was a road dyno that calculates that mythical crank HP number and not wheel hp.

Read! These are not estimates. Do a search.

I already said that above, "Can't say you can add the numbers and be correct."

Why try to pick a fight over something we have no disagreement about? It's clear I already addressed your concerns. I see no butt-dyno claims here, so leave that out of this.

I added proven individual wheel hp gains together, knowing that there are 33% losses from the crank that i purposefully didn't add back in, to subaru's claimed crank hp just to give him an idea of where he migh be. I made it clear this may not be good math. End of story. YMMV.

PS: I used subaru's claimed crank hp because nobody above my post could agree on wheel hp.

SCC gets 95hp, Cobb getts 128, Altered Atmospere gets 124, JC Sports got 98 front wheel hp on an automatic at 6000 feet, etc...

Wee. Lets repeat everything we've said already.

Okay, forget it. And I'm not going to be insulted by a moderator who isn't clear (or knowledgable at the time) when they write posts.

Final PS: Even SCC Magazine has added wheel HP to subaru's crank hp to get an estimate of power, such a when they gained approx 85hp at the wheels and added it to 165, to estimate 250hp crank.

They didn't feel it was fair to multiply crank hp by the % hp gained from baseline because it seemed too exaggerated.
