Dyno graph of S50.

[nando]

I think this thread illustrates why

1) comparing different cars from different dynos/operators on different days is pointless
2) using a dyno just to get a peak HP and TQ # to brag about is pointless
3) getting a baseline for your car from the same dyno/operator with similar conditions is important

nice curves, flat torque.. but it really doesn't tell us a whole lot without a baseline of your motor when it was stock.

Mazur,

Good looking numbers for a 3L. Are their any DynoJet facilities near you? I would like to see a DynoJet SAE print of your motor.

I dynoed 226 on a DynoDynamics, then took it to a friends Dynojet hoping that it would make 235+ (because we have all heard that DynoDynamics read Low) and it only did 218 SAE. I had it done again at the DynoJet and it read about the same as the first time.

I have a feeling that the DynoDynamics operators in this country are monkeying around with the calibrations, because they own the heart breaker dyno, and nodody wants to spend money on a dyno that reads low.

If you are reading 240+ SAE on a dynojet with a non-cammed 3L, I will be stunned.

Don't take this post the wrong way, I'm just curious about DynoDynamics and how they compare. I have seen that they read 10-15% lower than a Dynojet, but in my case (and I suspect yours) that the theory may not hold water.

Cammed motor only went up to 6800rpm, Mazur took his up to 7250rpm. And yes a cammed motor will keep making power up to 7200.

So an S52 with schricks only made 4hp more than you? I suspect some kind of error.

+1

The graph is waaay smooth too. Either it's being normalized or the chip is leaving a lot of power/torque on the table in favor of smoothness.

That's almost identical to my setup list. I'm using OBDII header with an AA track pipe though, and conforti chip...very cool dyno results. I was always figuring my car for about 220-230rwhp, your numbers are very good especially on a typically low reading dynojet.

^^ you know, i asked you that in one of your threads hoping you or someone would have a nice answer to that. i wouln't care as much for mileage as i would for my engine though. i think your car is badass, i actually hope my setup is somewhat similar!

do we get another youtube showdown?!

About the gearing? I must have missed it.


What youtube showdown? I don't have any vids. I guess I should make a vid though. Just have to find a friend who is willing to video tape while I'm carving it up on the canyons.:D

woah, that must feel pretty nice with 3.73 gearing!

I switched to a 2.93LSD Saturday night because I was going on a drive with the AZBMW crew and wanted better gas milage and less noise.

Well now I'm thinking I'm never going back. I think I'm actually quicker now because I don't have to shift so much. Raced my friends E36 M3 and I start pulling and he's shifting way before me....I love it! And 100mph in 3rd is so sexy.

And even with the hard driving we did through the canyon runs I still ended up getting better gas milage than with the 3.73 when I'm taking it easy.:)

damn, what can i say, s5x swapped e30's ftw!

[mazur]

This is probably a better comparison. This one was made on different day when it was 97*F outside, if that makes a diff.

Yea, the DynoDynamic that is here in town reads about 15% lower than a number of Mustang dyno's here.

[mazur]

Nice i need to get my car on the dyno. Where did you get the silicone 90* bend (replaces accordian)?

Just bought a 90* silicone hose that goes from 3.5'' to 3'' and fitted the ICV and crankcase vent tubes to it.

Those numbers are good .I hope to put down numbers close to this. Do you have pictures of the exhaust.

Only these...

shouldn't an s54 put down more???

I don't know. This is the only example I have seen of a stockish M3 on this Dyno Dynamics. Owner claims that you have to add 25% to the readings for a standard tranny to get HP. Sounds a little too optimistic, but I believe it does read a tad lower than a Mustang dyno in my experience with dynoing with both with same car.

[BingM3]

damn, those are WHP #'s??

Has to be wheel HP, that's what I'm talking about....mods work well on the S50 engine....I have 95% similar mods:) why I keep up with E46 M3's and a 95 E36M3 with Dinan S/C
