Well.. we hit a dyno day today.. insane turn-out.. must have been 50+ cars there.. including 3 Zs. We had a Z hold the top position in the 6 cyl non-boost group until a E30 M5 put down 360 hp

Second run was best. This was the first time the shop had done 350zs and they were very impressed with it. Alot of people commented on the engine's sound, and how it just screamed to have more in it.. it didn't even sound up to speed when the rev limiter kicked in! The shop guys were like 'I gotta drive one of these...' this of course after dyno'ing 400 HP 4cyl cars.. 600+hp supras, etc.. not exactly ghetto company

So the details: My 6MT Touring w/~2800 miles. Stock with just a K&N filter. Mustang Dynometer doing the pull in 4th gear.

Second run was 238.9 HP at 6250rpm, 228 TQ at 4500 RPM.

No scanner at home.. but here's the chart just to show you the curves.. people were drooling over the Zs flat torque curve.

Just curious, do you remember what the other Z's dyno'ed at?

flynnibus

Another stock Track Z dyno'd basically identical to mine. A touring Auto dyno'd lower. I'll leave it to VAGent if he wants to post his results.

Ok ok..no one ever told me about the *&&%^%!!! HP stealing properties of the Auto Tranny. (even though I should have known).

My best run of 3 was 222.3 HP and 215 Torque. I don't have the print out and I don't remember the rpm's.

Guess I'm gonna have to get better with my driving skills to make up the difference....


or, I was reading something about a Triple Turbo...

Hey guys,

Here is a scan of the sheet they handed me. First run 239, second run 238 and third run 236. The dyno operator said that once the cars get hot they lose power and my runs seem back this up. Not sure if the sheet is the second run or an average of the three runs. My car had 3400 miles on it and is completely stock. The dyno operator said that the Mustang dynos typically post numbers lower than Dyno Jet readings. In fact if I'm not mistaken he said it could read up to 10 HP lower than the Dyno Jet.

flynnibus

Where is this 239 dyno? I need proof my 238.9 isn't higher...

MilleMe

flynnibus,

Unfortunately for me I don't think they printed out the correct run or it was an average of the three runs. Did you notice that the torque is about 13 ft/pounds less than yours?

flynnibus

Odd.. they gave me the paper for both my runs. Maybe give them a call.. maybe they still have the data in the computer.

Your torque number is wierd.. did you run before or after they recalibrated the machine?

360HP for a normally aspirated 6 cylinder M5? Was that at the rear wheels? Hard to imagine it would still be streetable.

zmadnez

An E30 is an M3 not M5. Curious as to how the Z compares with the E30 on the Dyno.

Remeber guys....Mustang Dynos read higher than Dynojets.

flynnibus

Actually.. its the other way around. Dynojets read higher then Mustang.. and the Dyno version that runs on the hubs tends to read even higher.

And the M5 that pulled.. wasn't the 360 car.. if I'm not crossing the nicks wrong on bimmerforums.. not sure who pulled 360 now.. that was who was leading the board.

flynnibus

heres the comment on the M5

' Heh, that was an E34 M5. He put down 266 rwhp with a chip as his only mod. I dont think any E46 M3's ran, most left before about 5 I think."

max2000jp

I am almost positive that Mustangs read higher...I will find out from a friend when I see him next.

flynnibus

Well if you want to throw around unoffical sources.. here is from bimmerforums.com

I can tell you the difference based on my results. Also, I have two software chips (street and race).

Mustang Dyno:

Street = 370 rwhp
Race = 385 rwhp

Dynojet:

Street = 383 rwhp
Race = didn't get it done, but you can estimate based on street ratio of 383 rwhp (Dynojet) to 370 rwhp (Mustang) that the race setup yields 398 rwhp (385 rwhp on Mustang).

There was basically a 3.5% difference.

Hope this helps.

Actually, a Mustang dyno is going to give you a better real world figure to go on. I forget all of the little conversions from my motorcycle days, but a dynojet is a great choice if you are trying to post a figure on a website for status. Case in point, most performance or race shops will use a Mustang. But if you want a Dynojet #, any shop will do the conversion and tell you what you would have gotten on a dynojet. And yes, it will always be higher.

you draw your own conclusions

2001Stang

Mustang Dyno read lower then Dynojet dynos. Nice numbers TQ seems a bit low but has a nice curve.

menehune

Is that correct, you guys dynoed at 11:27PM(time on flynnibus' sheet)? Hardcore man. I notice that between flynnibus and MilleMe, the max torque differed by 13. Not bad for a K&N filter.

flynnibus

No.. it was at 6:11pm.. but we had been there since 11:30am! They were pulling even after I left at about 8:30 or so.

The torque difference I'd probably run up to a freaky run or just slight engine difference.. I wouldn't put the gain on the filter

VaGentleman

See..no one wants to comment on my poor 222.3.

NP....at least I have a Z and know I need a few mods NP
