Dyno Time...results inside

hppwdn · Post by **hppwdn** » March 5th, 2006, 3:08 am

So we stopped by the dyno today and made a few passes with the mx3ze. Before the results a little history that reveals some very interesting info.

The last dyno we did on the car it made 180whp. Since then I have only added pacesetters headers (didn't even come close to fitting right) and a UDP.

Today at the dyno it made 193.66hp & 169.84tq.

Not too shabby. That's still with stock ignition. For bolt ons it has:

2.5" Exhaust w/ 22 in resonator and Borla Muffler
CZT bored TB
Pacesetter Headers
No Cat
Unsprung 6 puck rx7 clutch with stock pressure plate
UDP
Millenia IM
EDIT: Since no one read my sig...Megasquirt Engine Management

So it appears that the pacesetters made 13hp at the wheels and about 13wtq since the UDP gains are pretty much non existant in 4th gear.

Anyhow on to the dyno graph. The choppiness is from that quality stock ignition

Coil packs coming soon....

Notice how the torque is pretty much right there when I hit the gas until the HP catches up.

Comments on what I could improve to reach the goal of 200whp all motor are very welcome.

Video of the dyno can be found here.

Very nice

I have always thought a standalone engine control system was the answer and your setup is similar to what I would like to do myself. When you start looking at ignition.. check into MSD systems.. I really think their multiple spark setups will get the most complete ignition/combustion per cycle. Are you running window switches? If not.. how are you setting your VRIS points?

One thing.. you are not the only person I have seen complain about pacesetter headers.. might want to check into SS Autochrome down the line.. I would recommend getting them ceramic coated even to better keep heat under control.

Also.. did you have your K8 TB bored out or did you have a millenia TB done?

Anyway.. congrats on some great numbers man.. cant wait to see your next upgrades and results

a msd ignition system would push you past the 200hp mark
decent fuel burn at high rev's !

Nice figures for minamal mods

Wait. This is supposedly with a Mazda ECU, no AFPR, and stock ZE cams? I'm going to raise the BS flag here. Your shop's dyno has to be WAYYYYYYYYYYYYYY off.

I agree the numbers doesn't seem right, with the mods you have you should be in the 160whp range. but good curve on the dyno though. For sure it has to be recalibrated.

About pacesetter headers, on thing I heard is that they have the most horrible sound but are the one that give the more hp

Yeah that does seem unrealisticly high. Those are by far the highest number i have seen on this site for the ze. You should try a different dyno.

a quick database you can look at

For those doubting me I find that pretty amusing.

The engine management is a megasquirt (see my sig). VRIS is controlled by MS and set at 4000 & 4700.

TB is a KLZE TB with the CZT 70mm coned to 67mm bore. I had an extension made so the IAC would clear the thermostat area.

We also tune the car with a wideband on a regular basis.

As for the headers I sanded them down real good and painted them with high temp paint that has not peeled at all and is sticking really well. To make them fit we had to pretty much hack everything up and re-weld it together.

For ignition I'm upgrading to a V3 board for MS and adding coil packs.

The dyno is fine too. It's actually a very well respected dyno. They do a lot of dyno business for a lot of the fully built Honda/Acura guys running those crazy 500WHP+ 10k rpm engines.

I agree the numbers doesn't seem right, with the mods you have you should be in the 160whp range. but good curve on the dyno though. For sure it has to be recalibrated.

That's completely wrong. Regular KLDEs with I/H/E hit 160whp all the time. So make that a very healthy ZE, add some more bolt ons and a stand alone and you do the math.

B4TN was not running an MS. Of all people BabyBlue you should know the benefits of MS on a ZE.

Lakersfan1 - do some research on how a stand alone works. I don't need the AFPR to control my fuel. I've been running it that way for close to a year with no problems and so does most everyone I know with an MS.

babyblueMX3 · Post by **babyblueMX3** » March 5th, 2006, 9:59 am

you should have stated in your first post that you were megasquirted

Now I understand.

a friend of mine that had a full ZE, intake, headers, exhaust, FPR, made 157whp ona mustang dyno.

Brian (b4tn) wasn't even running a KLZE, so...please read more carefully.

Why do you guys call BS? There is a DE running around in the New England area with a 189whp using boltons, reground cams, and a MS (see the thread in teh PT EE forum).

Lakeersfan1....looks like your "knowledge" is WAYYYYYYYYYYYYYY off.

When it comes to dyno's you really shouldn't go around switching them as you progressively add more mods. Then you do not see consistent gains. At the very least if you look at his first plot with this car at Car-Tek, you will see somewhere of around a 15whp increase with the addition of the pacesetter headers. Nothing else changed.

babyblueMX3 · Post by **babyblueMX3** » March 5th, 2006, 10:03 am

if we had known he was MS'ted since post #1 nobody would have said anything about it
btw Jordan, did you dyno the ze-t ?

shaodome · Post by **shaodome** » March 5th, 2006, 10:06 am

No

It currently is in N/A form. It is undergoing some major upgrades and since I'm selling my dail driver (buying a new car). I need to keep it safe for a few more weeks. Rest assured...300whp commin at cha!

I'm still waiting on the word for sending in my ECU for the V3/coilpack MSnS conversion from the first GB. Down payment done a long time ago and springs a commin'.

I know...we are a little backed up. I am having ryan do all the PnP units, so you will be shipping yours to him. I'll e-mail you the addres to mail it to
