Well I finally got the car dynoed today. Yea well I'm a bit dissappointed and here is why
RUN I:
Conditions: 64.29*F, 29.95 in-hg SAE 0.97
CAI, Revco TB, Magnaflow muffler, AFPR
126 whp
129.77 wtq
RUN II:
Conditions: 64.85*F, 29.95 in-hg SAE 0.97
above and 55 wet shot N2O
157.81 whp
172.39 wtq
Thinking it should have been more but oh well.
I'll post the actual dyno sheet when I get back home Sunday (laptop have no floppy!!)

Sounds about right.
Be kind to dragons, for you are crunchy and taste good with ketchup.
what kinda dyno?
It does sound right for a mildly modded eco.
Dynojet 248 was the dyno. I just thought it would be more than that

I'm guessing you're getting about 170 at the flywheel. Considering it's only minimal bolt-ons, that's pretty decent. If you want more, replace the entire exhaust, cams, get the ecu tuned, and lighten things up a bit. Pulleys, flywheel, etc. The lightweight parts won't "make power", but they'll free up the power the engine already makes. I don't know what N2O kit you're using, but I know the NX kit for the Eco' rates the output at the wheels. In other words, a 50-shot is more like a 75 or 100. That's a ton of giggle gas for a stock motor.

Yea thats what my next plans are. 4-2-1 header (need to restore low end), high flow cat, 2 1/4" piping, and crank pulley. Im using Zex right now and it is rated at crank. Maybe an up to a 75 shot is next.

Those numbers without nitrous are right on. If I remember right the throttle body you bought off of ebay is the same size as the stock at the butterfly plate. And untill you do a whole exhaust those numbers won't change.

idk about the eco tb but mine for my z24 has a bigger butterfly in it.

boost will be soon for me....
Wow.. an Eco with bolt ons only that lil whp? Man.. now I don't want to dyno mine. I thought you just take 10hp off the bhp from fwd cars and that would be a close estimate to whp. Guess I was wrong..

130 whp here........mustang dyno...........mods listed in registry
120s seems kinda low as most ecos are at least in the 130s stock as a baseline should have seen closer to 180whp

^ "scruffdog", huh? you have quite the name to live up to...gl
fortune cookie say:
better a delay than a disaster.
I have dyno charts of an 03 stock Dyno'd at the wheels of 125.
I dynoed 156whp, and 189lbs on 6 psi on my 2200.
Those numbers do sound a bit low. maybe you just need some good supporting mods.
Yeah every car is different. I dynoed 140.6 last week. I wouldn't be that upset about your numbers.
From the looks of it, it sounds about right. An intake and muffler are only going to do so much. Your throttle body isn't going to do much either without other breathing modifications.
The nitrous dyno looks about right as well.

yea you are wrong
its percentage, not minus 10hp
take about 10% off of bhp (brake horsepower... hp at the flywheel) for a manual transmission, and about 15% for an automatic to calculate estimated wheel horse power
and think about 20% of drivetrain loss for an AWD vehicle... maybe even more
and FWD RWD drivetrain loss difference is minimal. you still spin gears and a differential. Granted, the driveshaft weight does make a difference, but like I said its not enough to really take into consideration. Remember, this is only a GUESS.
plus all dynos are different...
also, elevation comes into play, as well as temperature, humidity, etc etc... my point being one car could dyno 130whp and on another dyno 120whp.
With nitrous, bottle pressure and bottle temp (somewhat related) will make a difference in power from run to run... even consecutive runs done within minutes of eachother. nitrous tends to be touchy unless you excersize a lot of anal retentivness in control of the bottle.. and even then its like a 70/30 chance you'll get what you wanted.

an intake and a questionable throttle body with a muffler isn't really bolt ons... I'd consider that an intake at best. some real exhaust work (ie more than a muffler) I'd consider a car with 'bolt ons'
With the exhaust work, you'll see much bigger gain as everything works better together as a team. And double check that throttle body to the OEM
Last year Super Chevy tested an 03 Eco and with a 50 shot, CAI, Magnaflow cat back and it made something like 190 HP but I believe they also blew the motor. Go figure.

the throttle body has a 60 mm butterfly. when i got it, it looked alot bigger then the oem one. and yes i know that the exaust is choking my car with out the pipes and a header. I'm working on getting that fixed but its hard to work on a car and take care of a new born at the same time. those fu&%ers grow fast as crap and cost a lot!!! Adam knows what I'm talking about. Everything i got for the car i had before the kid, with the exception of the TB.
PS. I'm open for donations...

guys guys! dont get all caught up in the HP hype.. run it at the track if you want to compare true performance. dynos can be configured to really alter the output. they can make up crazy numbers if they are setup wrong. those numbers are not off enough to say yah or neh on the dyno.they appear to be on the low end of things but not crazy low..
using the same dyno will you get an idea of gains as you continue to mod. using % works the best as well.. say i saw a 25% gain from such and such.. gives a better idea of mod benefit than just x hp from y dyno. my .02 though
Sven you totally quarterloafed your computer..
that is kinda low man, my 2.4 with a plastic pvc intake, tb, muffler and the non power adding mounts laid down 137 whp and 151 wtq
parting out my built and boosted 97 z24 so4x4.com/cavy.html for pics and a parts list
