Dyno'ed the Legacy (post your dyno plots here)

**rougeben83** · 11-18-2007, 12:13 AM

Mustand dyno day today...I won the lowest numbers award

TWE Header, 2.5" catback, CAI is pretty much all I have done on the SOHC EJ25...

Gotta love the torque curve though. It was probably the only thing the other guys were pretty impressed with

**Plays_with_Toys** · 11-18-2007, 12:20 AM

knowing that your motor is on average 30hp greater than mine... I'm saddened...

**Reason** · 11-18-2007, 12:31 AM

How many miles? my 97 GT had 117hp. The only difference was I had a short ram, only a cat back and a lighten crank pulley. This gives me hope to what I have planned.

**rougeben83** · 11-18-2007, 12:52 AM

Has about 83k miles on it. I'm guessing the car makes about 175-180bhp at the moment, conservatively. Keep in mind this is on a Mustang Dyno...stock EJ25's have a hard time breaking 100whp on these things it seems.

I wasnt really sure if the lightened flywheel (14lbs vs. 30lbs on the stocker) counted as a power adder, so I just left it out.

You should see some nice gains with a header.

Mine was on a Dynojet, and I know it was pretty warm that day

**MCarp22** · 11-18-2007, 12:18 PM

The light flywheel won't show up on a mustang dyno since it measures force and not work.

**Reason** · 11-18-2007, 01:46 PM

Here's mine, maybe I'll make this a dyno sticky for future reference.

**MCarp22** · 11-18-2007, 07:04 PM

Mine was at speednation in Pittsburgh PA.

**Reason** · 11-18-2007, 07:22 PM

I mean what kind of dyno? Dynojet, Dynapak, Mustang, etc?

**MCarp22** · 11-18-2007, 08:34 PM

Oh, right, both were on a mustang dyno.

**auspex** · 11-18-2007, 08:41 PM

this would be fun...except there isn't an AWD dyno in the entire freakin' state of Idaho.

How much it usually cost to dyno your car?

**MCarp22** · 11-19-2007, 06:59 AM

Dyno pulls cost anywhere from $30 on a group rate dyno day, to $250+ for full wideband and tuning whatever engine management you have. Average cost is probably a little under $100 or so for the basic couple pulls with time to make changes.

**Reason** · 11-19-2007, 08:26 AM

I paid $75, 3 pulls with wideband, this other place is $85 I think. But like MCarp said it all depends where and what service you do. If you want 3 pull to get a baseline I would think anywhere from $65-$95 for 3 pulls. Wide band monitoring is like $5-$15 more.

**rougeben83** · 11-19-2007, 04:38 PM

Dyno day, 3pulls/$60

**d1giPhux** · 11-19-2007, 07:40 PM

Man.. they really make their money in gold on those machines! Why is it so expensive?

**Reason** · 11-19-2007, 07:51 PM

It's an expensive piece of equipment. A dyno jet can be close to $80,000. I'm sure the AWD dynos are more money than 2WD. Then you have to pay the trained techs. It's precise work, you don't want to screw up cars.

Yeah, an awd dyno is around the cost of a house (100k+...just google dynojet or mustang dyno, they have sites).

What you pay for is to have an accurate tune of your car with whatever mods you have on it.

Case in point, during the dyno day there was a guy that was having problems with his Utek in his FMIC'd wrx wagon. The problem? A crappy street tune. No matter how much on road tweaking they tried, they couldnt get it to idle right. AFR, 02 wideband in the muffler and some pulls on the dyno and they were able to tweak it and get it to run nicely...on top of that they made more power than what they had before.

Also, we had a stock 06 WRX on the dyno, a few minutes to reflash the car and they managed to get another 30ft/lbs at at the wheels from the car - nothing mechanical was done, just a couple of dyno runs and tweaks on the ECU.

The place where I had mine done is selling theres for only 50k

Gotta make sure you get all your [ and ] correct:

Wow, so it's not worth modding a NA 2.2L.
