I'm trying to consolidate as many dynos as I can. I'm looking at the torque on the graphs and estimating what value it's at, then averaging the torque values and, through the equation ((lb-ft*rpm)/5252)=hp, getting an estimation of horsepower. The more graphs I can get, the more precise my calculations.

The data tables I have set up are as follows:
Stock
Intake
Exhaust (axle-back)
Exhaust (cat-back)
Exhaust + Intake

Once I get a good amount of data (at least 4 sets of data/graphs per data table), I will post the data tables and the result graphs. You'll be able to see the average hp and torque for stock Fits, ones with intakes, ones with exhausts, and ones with both. I'm hoping it will give everyone (and n00bs) and good idea of what sort of gains to expect from intakes and exhaust, as well as a good comparison table for different intakes and exhausts as well as intake/exhaust combinations.

I already have these:
Stock: Fujita, Aspec, dragtimes.com, Weapon-R, Jackson Racing, Import Tuner, Temple of VTEC, Sport Compact Car
Intake: Fujita CAI, Aspec, mishimoto, PasswordJDM
Exhaust(a-b): Aspec
Exhaust(c-b): none
Exhaust+Intake: Aspec

So let's see those dyno graphs!

(P.S. I already searched the site for dyno graphs. I probably missed a few, so let me know!)

I have consolidated the data from 8 different stock Fit graphs. This is the result:



This is using data from 4 different dynos for intakes:



This is stock vs. intake



Already, you can tell that adding an intake, on average, will give more hp (especially at 6.5k) and smooth out the powerband.

If you'd like to see the graphs different (i.e. make it bigger, change y-step to 5 instead of 10, blah, blah, blah) just ask and I'll get it done.

I don't have enough data to post the intake (2 sets of data), exhaust axle back (1 set) and intake+exhaust (1 set) graphs. I have no other data.

 

Made some big upgrades this weekend, checked out my dyno!

 

^ Not what I wanted, but deserves rep nonetheless.

 

lol nice graph. usually stock gets the smoother powerband though lol, but i guess these are some really nice performance wheels so i don't know.

 

hahaha sweet! all i need are some fast and furious decals and a aluminum wing and i should be rollin!!!



cojaro, thats a good idea, it will be interested to see what all the results show.

 

bumpity bump this'll be a good reference

 

Bumpity bump. C'mon people! I know we have more dyno charts out there!

 

BUMP

Cojaro is doing some good work! Help him out peeps.....

Once done this should be stickied.... really helpful to get an idea of what mods could potentially do for the Fit.

 

I will try to help you out. Here is a dyno set for my Fit before installing Pulstar Pulse Plugs, with the plugs installed, and then after taking out the plugs because of the detrimental effect it had on my engine.

 

So is that two stock runs and a run with the Pulstar? If so, something seems very wrong.

Either way, we can definitely say that aftermarket plugs probably won't do much at all.

Thanks!

 

Yes, run 1 and 3 are stock setup. Run 2 was with the plugs installed and it caused my car to misfire and go in to 'limp mode'. It is most likely that one of the plugs is defective, but I wasn't going to risk installing the plugs again.

 

There are dyno graphs on the T1R Header thread, the T1R Intake thread, and the Weapon R Street Header thread.

 

Baseline (Blue) Bone stock
vs
T1R header + intake and exhaust (Green)

 

once I get my header and bpipe I'll get a dyno for you of I/H/E w/o a cat delete, it'll be about 3 weeks though :-/
