Default #120's Dyno...

Well after about 2 years now of many persons on this forum and myself wondering how much WHP my 98 Itr would lay down, I have dyno'ed the R.
98 Itr with 75k, stock motor. Mods are:

-Comptech Icebox/K&N E2427/stock Upper Elbow
-OEM JDM 4-1
-SMSP 12" Test Pipe
-Buddy Club Spec 3
-Timing @ 17deg.

This setup along with Drag Radials netted consistent 13.7's@100mph at the drag strip and a Very Strong motor on the Road Course. I dynoed the car at http://www.hpworks.com. The owner says there Dyno is calibrated on the lower side also, as many will agree. It was 82deg F out side with 68% humidity.

That looks familiar.

I'm not surprised by the HP, but I'd have expected more of a VTEC spike.

Wait. That sounds familiar, too.

:P

Oh, and if you people would give up and switch to AOL, you wouldn't have trouble with your FTP space going down or exceeding bandwidth restrictions.

What is the deal with the vtec spike? Mine is SUPER violent.....



Mugen Intake - JDM OEM 4-1 - Fujitsubo RM-01A - 18 degrees timing (red)
Blue = 21 degrees timing.

The vtec spike is the huge amount of fuel that the stock computer throws in ~4500rpm in preparation for the huge increase in air flow once the larger lobe is engaged. Honda didn't want these kaas break'n

Here's an old map of my car 3 years ago tuning that crap out-a-there by lowering vtec & letting the air in!!

It's still a little spiked because the Field only lets you tune at 1000rpm increments.

It looks a little smoother on the mustang dyno (although #'s will always report lower - the mustang dyno is where I tuned the fuel out.)




Anyway that's my .02

maybe you also had more power because of advanced timing?

If you are referring to me - the car was a daily driver for 4 years, so I left it at a safe 17 degrees.

You can see the mods here. I haven't "redynoed" since I added the lighter flywheel. Total mileage = 113,000 & I haven't done any motor work yet

To see mods just view my gallery page: www.itrca.com...budman

We put my car on the dyno when it was equipped similarly to Smitdog's car. From the dyno chart, you can see why I expected a big VTEC spike. You sure Sakai hasn't been messing with your computer? LOL....

In this guise, the car would do 13.8 on Azenis, so your figures make perfect sense.
