Paul Magee's dyno

[mageep]

We just completed a dyno day today... At Mustang Dynamometer Corp HQ up the street in Twinsburg... (Thanks Tim Gentil...)

I was looking at it principally as a chance to check out my AFR... I assumed I'd pull MAYBE 210WHP...

Wellll, check the below: 225 peak whp / 178 lb ft! Needless to say I am pleased!

Also, check out the AFR. I originally had it about 11.5 or so in the meat of the curve, but on that run it pulled about 4 hp / 4 lb ft less, and the Mustang guys said they heard some knock at the very top-end (I didn't hear it, but my exhaust was droning in the building, and I trust their ears)! So I cranked in one more step on the eCool PC Pro...

BTW, the HUGE spike in AFR was a sensor anomaly (this is confirmed by the lack of any corresponding change in either HP or torque).

Tom, THANK YOU!

[bogey]

WOW! That is impressive.

[chuckerants]

holy crap, that is impressive!

Question from the idiot from Olympia, WA.

What results should I get running 92 octane in a 96, no other engine mods and with the largest (?) pulley that Tom has?

:stuart:

[Race Grandpa]

And it is the :cool: side SC.

Paul what size pully are you running? I have a 99 10AE with 265 cc injectors (240cc is stock) with RB header / catback running a 110mm.

I would luv to have those numbers... heck thats more torque than Tom had running 130mm... is that ...wait a minute.. are you that guy up in the high elevation?

regardless... congrats... still what size pulley? please

thank you

Hey Buck... The Sig is accurate that I have only ever run a 115... Elevation is not bad around here...I just posted that dyno, but I think it's safe to assume it is a pretty generous dyno, at least by Mustang standards!

[Dr Evol]

The mustang dyno is very generous. My stock Miata pulled 122HP on the same dyno and only 112HP on a local Dynojet.

As Paul said, his goal was to fine tune his A/F ratio and get the best HP and TQ without ping.

I need to get my PC Pro installed along with my wideband so that I can finally put on the 120mm pulley. I have to do something to try and keep up with Paul at autocross. :sweatdrop:

Paul's car at yesterday’s autocross definitely looked like he has a few extra HP.

NOTE TO SELF... loaded up with lateral Gs, pea-gravel, and an extra 80-100 HP to learn to drive with = 360 degree spin.... Actually 2 180 degree spins! :stuart:

Chip, on the other hand looked excellent in the Mazdaspeed 3... GORGEOUS car.

[jrmotorsports55]

Very nice numbers. Can't wait to get my car to that point.

Oh I see it now.... wasn't paying attn. You know reading is a form of listening and I hate to listen... wife says I suffer from selective hearing loss.

Anyway good numbers bro

I luv Saints & Sinners :alucard:

From what I understand Mustang Dynos would theoretically read higher than Dynojet below a certain hp level. The reason is that the reading on a Dynojet is ~ 26hp lower than flywheel (for the Miata based on the general consensus) regardless of the power output. In contrast the Mustang dyno is reading more closely to actual rwhp which is ~ 85% of the flywheel. For example:

116 flywheel hp:
Dynojet = 116 - 26 = 90rwhp
Mustang = 116 * 85% = 99rwhp

140 flywheel hp:
Dynojet = 140 - 26 = 114rwhp
Mustang = 140 * 85% = 119rwhp

175 flywheel hp:
Dynojet = 175 - 26 = 149rwhp
Mustang = 175 * 85% = 149rwhp
(this is where they equal each other)

200 flywheel hp:
Dynojet = 200 - 26 = 174rwhp
Mustang = 200 * 85% = 170rwhp

250 flywheel hp:
Dynojet = 250 - 26 = 224rwhp
Mustang = 250 * 85% = 213rwhp

300 flywheel hp:
Dynojet = 300 - 26 = 274rwhp
Mustang = 300 * 85% = 255rwhp

In other words 225rwhp on a Mustang is very impressive!!!! That comes out to ~ 265 flywheel hp = ~ 239rwhp on a Dynojet!

Looks like you are forcing me to order a 140mm pulley from Tom for my R4 setup afterall... It's all your fault :)

I am curious what others have done to run the 115 pulley without ping. What gas was the dyno run on? Do you have any timing mods? Are you running stock injectors? Stock compression?
Thanks

Sunoco 94... ZERO other mods. This car was literally a C-stock car the day before I started the FFS build. The engine has never been opened. Just broke 83,000 miles yesterday.

So yes, stock injectors and stock compression, and I made no mods to the install. By the book (well, I think I rotated the EGR valve body 180 degrees! LOL)...

It pinged with the BASE settings on the PC Pros, but Tom advised me to bump up the eCool PC Pro accordingly, and I think we're good... The AFR illustrated on the chart above seems to show it's OK. I am NOT at the end of adjustment on the eCool PC Pro, but I'm almost out of headroom with it. Only 1-2 more clicks to the wall. Any thoughts of a 120mm will most certainly also include a re-burn of the eCool PC pro to get a wider adjustment range...

Awesome results. I'm jealous. :)

I dunnno 510 your theory of 26 seems abit off most of the time mustangs read 10% lower the Dynojets anyway. Case in point the mustant i ran on rutienly had several s2000's on it for tunning purposes baseline runs etc. And the operator stated that they all pulled from 170-180 whp on there machine. Most people report about 200 whp out of a stock s2000, given 240 or so chp. so this would be equivalent to 240-250 dynojet whp very impressive man. :)
