BMW E46 330 ZHP and Non ZHP Dyno graphs.

[danewilson77]

Post if you have them run on your car......or if you run across them on line.

Thanks.

This guy pulled:

2003 BMW 330i ZHP (mileage : 19,900)
HP : 207
TQ : 200

[danewilson77]

And another....

OP's comments.

Car is 330i zhp, with only Conforti intake and pulleys.

Got about 209hp at the rear wheel. With 15% driveline loss, that is about 246hp at the crank. Not bad considering factory rating is at 235hp.

From the graph you can see the 4200rpm dip. This is the most pronounced I've seen on any ZHP's dyno chart. I don't feel it at all when I'm driving, just hear the engine get louder at that rpm.

Be sure to note the type of dyno the car was measured on.

DROIDstatus. Come at me, bro.

[johnrando]

Interesting, as a "bone stock" is only 2 HP behind a "Conforti intake and pulleys" dyno, so clearly a dyno difference? John

[mikeyb74]

I would thought the dyno numbers would be a tad bite higher. My Altima 3.5 V6 dynoed in at 218 at the wheel. That was with the Nismo CAI and underdrive pulleys. Nissan claims the VQ35de in the 02-04 Altima has 245hp at the crank.

[Hornung418]

I6 motors sacrifice some hp for smoothness and vibration reduction.

DROIDstatus. Come at me, bro.

[danewilson77]

Again...I think I am finding out, that dyno accuracies differ pretty widely.

The peak numbers on this dyno are not accurate. That jump at the end is due to a calculation error as the clutch is pushed in at the end of the pull and the drum speed and engine speed are no longer linear.

Of course, you guys know every dyno varies, and the most consistent by far are inertia dynos that have no user adjustable correction factor.

You know, looking at this graph from Turner, it is interesting to see that with the shark, the 4k rpm dip/timing pull is just as present as without. I don't think the shark is our fix for that.

Ian

[danewilson77]

In addition to the other post in "Performance" section......maybe it feels less pronounced for me as I not only got the Shark, bt also was updated to latest 330i ZHP software.

Just as a reference, here is the thread from e46F. (http://forum.e46fanatics.com/showthread.php?t=768715)
I think when one posts a graph, they should list their user name, engine, mods and dyno type as per the thread linked above. Easy to get a comparison between mods and motors.

Justin, don't worry about naming other sites. I think we are pretty secure about what we have here. Naming names is fine here.

LAME...I'm eager to see.

I've been looking into Cosmos Racing (http://www.cosmosracing.com) for the M52tub28...doesn't fit 330 coupes or M3s tho :(
Great gains for the price...And I'm sure it's equal to or better than the Dinan long tube intake with similar specifications...

Both are stock runs. My car has always been a strong car. My best friend who was a BMW tech during the E46 days always compared it quicker to other ZHP's he's driven. It's a fun car for sure...I'm not sure that because I redline the car everytime I drive it that my car has come to get used to performing. LOL. It's like training a runner...you don't train walking around a track, you train running hard! :roundel

[danewilson77]

Looks like your lag is at 3600 rpm......208.......dayum.

Droid X! Srs Legitness!

[Rovert]

If you look at my Supersprint exhaust video can you tell the lag when I give it? I sure don't feel a thing when letting the car play. :D Those are all base runs. My modification runs are probably around 215RWHP which I'm hoping to increase with a new ZHP tuning program from my friend in SoCal.

You don't feel that dip?

That is really strong #s especially for a mustang dyno. I'd like to see the cf.

Who is your friend in socal for tuning?

Ian

[Rovert]

What's CF mean?

And no I don't feel it. Listen to it in my exhaust videos....you probably won't hear it or see it on the RPMs either.

My friend Jeremy is from OEtuning.com. He is a well respected engine tuner for years! He just made significant gains on all the E90 325, 328, and 330 engines all of which are NA. I have more research and questions to ask him before I share all this stuff with you. For me if I am here to offer something that I can root for, for someone else to buy, it has to be of top quality. You guys are a rare high quality type of users here and I respect that a lot. I'll also respect that anything I have to recommend is of the highest of my standards....you guys aren't second rate people here at all...so why should my opinions be? :)

[kaboom]

Correction factor. A dynojet is the only dyno out of all the brands where there is no way to add in a user defined correction, in addition to standardizing factors such as SAE, DIN, etc...

A SAE corrected mustang dyno generally reads 10-15% less than a dynojet, making your numbers even more awesome. Your car must be a hoot!

Ian

[Rovert]

I know that dyno's don't really mean anything unless you're using it at the same time to compare modifications. That's when you can truly see the differences with the same conditions. Other than that I guess the only similar way to compare car to car across state is just doing a quarter mile even though elevation and weather could play a slight role in the final outcome.

[Nivo]

I will be adding my Stock dyno runs tomorrow, The dyno is a Mustang 1100-SE AWD.
Using 93 octane and 5th gear.
air fuel is all over maybe from a torn intake rubber hose.
Weight on dyno day was 3287lbs.

[Sockethead]

So I got my car dyno'd at Mid Ohio a couple of weeks ago. 2 pulls for $20 for charity.
The weather conditions were almost perfect: low 70s low humidity... So I'm wondering why my car only pulled 193 HP..... Especially since I have Dinan CAI, throttle body and stage 3 software.
I was hoping to at least see it over 200 hp... Also I was surprised to see maximum torque so high I thought max was at around 3500 RPM.
Also there is a strange dip at 4k... I think that's the disa transition... i already had the DME done for that.

http://i424.photobucket.com/albums/pp325/r_powell123/dyno.jpg

[danewilson77]

Wow...that dip issss strange at 4k. What could it be?

Looks like you have >15% power train loss. Dyno accuracy may be playing a role as well.

I'm thinking of going back to the place that installed the Dinan stuff and saying WTF?

You know, I can feel that dip at 4K too... almost like a fluttering, that's why I'm thinking DISA. I had it out twice and it looked ok though...

[ZHP-FTW]

Have you replaced your vanos seals? That could be causing your dip and any loss of power at 4k rpms.




EDIT* Yeah, I forgot it usually causes a power loss around 3k rpms not 4k.

[kayger12]

Have you replaced your vanos seals? That very could be causing your dip and any loss of power at 4k rpms.

Bad Vanos seals shouldn't cause power loss or dip at 4k.

Vanos is typically loss of torque/power down low followed by surging at 3k, iirc.

Droid X. Tapatalk. Use it.

[Sockethead]

I replaced the VANOS last spring. I haven't had the time to talk to the Dinan guys yet. Been swamped at work...

Notes:

- It looks like my car has almost no knock adaption at 4k- this was with the stock (updated) DISA and probably the revised software. I have a sheet with smoothing at zero that shows the same very mild dip.
- The AFR for the factory tune looks quite good.
- Not happy with the steep drop off after 6k- seems a bit too steep imo.
- The water pump bearing was failing and making all kinds of noise- so I actually figure it might have sapped a couple hp. I will re-dyno soon.

Nah sorry, I was pretty vague in my post. I responded first by asking you for your dyno graph with aFe- then by saying I could post my dyno sheet.

No mods at all on that sheet. Just lots of maintenance and the like.

I6 motors sacrifice some hp for smoothness and vibration reduction.

DROIDstatus. Come at me, bro.
They shouldn't. I6s are inherently balanced without having to have balancing shafts or anything like that. Overall there should be little difference in efficiency (with slight edge going to the I6 if all else is equal)


I would thought the dyno numbers would be a tad bite higher. My Altima 3.5 V6 dynoed in at 218 at the wheel. That was with the Nismo CAI and underdrive pulleys. Nissan claims the VQ35de in the 02-04 Altima has 245hp at the crank.

The Altima is FWD - generally less rotating mass (no huge driveshaft), so they tend to be a little more efficient. And the VQs are particularly strong engines.

[JupiterBMW]

Another thread from the past... Heh, cool...

I'd like to add a few points... This is all really tough to compare. A lot of things come into play such as ambient temperature, barometric pressure, humidity, and elevation/location... So, its really hard to compare dyno sheets from different people all over the place. Even the big fan that some people put in front of the cars, will make a difference...

Also, in regards to the Altima... I actually took my old Altima SE-R to a 350Z meet/dyno day once... All of the Z guys (with mods) were putting down 220-230 at the wheels... My Altima put down 244hp... The Z guys were all shocked... Drivetrain losses... They do exist! :biggrin

[Hermes]

I need to post on this thread... maybe the E46 will make it's appearance after TMS pulleys, and I might also dyno the E21 just to see how efficient that engine still is. The 02 will have to wait until it gets a swap before it gets tested because I don't care about that motor anymore after recent revelations about the component makeup.

Something seems fishy to me... To think that just headers and an intake would yield soooo much power over stock doesn't seem right. Is that your car's dyno, Wyatt? How many runs?


Sent from my iPhone using Tapatalk

[Hornung418]

Headers are good for 15 or so.
A proper intake is good for 7-10.

Fuzzy math says it's not that crazy if a stock car dynos at 205 WHP.

[az3579]

From dyno graphs I've seen, intakes don't really do anything significant on our cars... 7-10 is pretty significant.
It's nice to finally see a combo of mods that are actually effective.

From the sig, I see there's a Simota intake listed. Isn't this the GruppeM with a different brand?

[QC_ZHP]

11:5:1 Compression

[Hornung418]

A proper intake such as a long tube or the performance intake is where the power is made. You gotta smooth the air flow before the MAF reads it. I know my intake makes a shitload of power when the DISA opens. So that shouldn't be too hard to make gains. The real restriction is in the head work.

[az3579]

11:5:1 Compression

How exactly do you get that without engine work? There was mention of there not being a tune, but I didn't think that changes compression anyway.

[Hornung418]

BP, Wyatt's engine exploded...he rebuilt the whole thing himself with 11.5:1 compression.

[QC_ZHP]

Wyatt's car is going to make more power than a stock M54 w/ identical mods everytime. I think the stock ZHP compression ratio is 10:5? His motor is 11:5, allowing it to max the output

Edit: couple of posts since I submitted mine.

Dario and Hornung posted while I wrote this, but yeah no tune, he definitely has engine work. Should make some great #'s after some software. + 3.64 LSD, its gotta be a blast to drive

[LivesNearCostco]

So what does Wyatt need to do differently, run 93 Octane gas?

Here's my latest dyno sheet from a few weeks ago. Originally dynoed at 190RWHP. Then with Shark Injector and pulleys got to 199 or 200. Adding aFe Stage 1 intake (plus replacing CCV, cleaning throttle body) made it 209 or 211 RWHP. The same shop/guy did all 3 dyno tests, but between my 2nd and 3rd tests, he moved the dyno out of his shop and into a truck, making it a mobile dyno. It's the same physical dyno but not sure if moving it to the truck changed the calibration. Stock manifolds and stock exhaust. I did go to lighter wheels in 2nd test then same lighter wheels with stickier tires (pumped up to 40 psi) in the 3rd test. Don't know if having heavier (OEM) wheels in first test lowered the result.

You can see the dip at 4K but I don't feel it when driving.

It is hard to compare dynos from different days. There is all kinds of atmospheric changes that will change your dyno numbers. Just keep that in mind as well.

True, and the dynojet will always have higher numbers than a mustang dyno. The mustang dyno is probably more accurate though

The roller system that your wheels go into. The dynojet has a drum style roller, where as the mustang dyno has dual smaller rollers on each side of the wheel. Providing more resistance to the area of measurement

There's typically a 13% difference between the two dyno's, say you make 200hp on a mustang dyno, 13% of that is 26hp, on a dynojet the same car will make 226hp. The mustang dyno is of a "street horsepower" measurement

As you can see from my post with graph on page 3. I had some pretty shitty numbers for the amount of work I have done to the car. Idk what that is. I've done an exhaust since then but I don't think that changed the numbers significantly.
I ran the car at our local strip and the best number I could get was 14.5 at 95.4 mph. Granted I was spinning through 1st and part of second, even with an LSD but I expected my MPH to be a little higher. It was in the height 30s that night.

I would take it to a different dyno. Doesn't sound like they corrected the numbers very well.

Absolutely true. All 4 of my dyno runs were on DynoJet dynos, and the last 3 were done by the same guy at the same altitude, though he did relocate the drum. Weather was a bit different:
Test 1: 75-80F, pressure and humidity unknown (different DynoJet)
Test 2: 83.7 F, 30.14 inches Hg, 21% humidity, SAE 0.98
Test 3: 63.0 F, 39.30 inches Hg, 66% humidity, SAE 1.00
Test 4: 70.0 F, 29.45 inches Hg, 29% humidity, SAE 0.99

The surprise to me is the only mod change was the aFe intake giving 9 or 10 extra RWHP when it's supposed to give about 4-5. Could be because I also have tune and pulleys, or could be one of the maintenance items I did helped (vacuum leak?), or could be variability in the dyno and temperatures. Between 2nd test (late 2012) and 3rd test (March 2014) I did GAS DISA repair kit, replaced CCV, changed transmission fluid, changed diff fluid, replaced guibo/CSB, and changed to stickier tires which were pumped up to a higher PSI (and tires might have been lighter too).

About 143,000 miles at Dyno test 1, 144,000 miles for Dyno test 2, 166,000 miles for Dyno test 3, and 186,000 miles for Dyno test 4.
Can't find dyno sheet from test #1 but my notes say my car measured 184 RWHP. Tests 2/3/4 used the same dyno but under slightly different conditions.

Test 1: 184 rwhp (100% stock, no fan on radiator)

I've since reinstalled the underdrive pullies, along with an overrunning alternator pulley (its within 2mm of the underdrive pulley size too) and I definitely notice a difference, so I'm keen to go re-dyno at some point.

Mmmmmmmmm, that's nice! :drool

How many miles on your car?

Oh its fun! I'm at 117k miles now, and counting... quickly :)

I'll chime in later on the dip at 4k as I am at work now. There is a very similar dip present on the FA20 motor in the Subaru BRZ right at 4k rpm.

Glad to finally see some charts

What mods do you have on your car?

[Vas]

Not bad numbers at all for just bolt on mods and a tune

I couldn't get my car over 200 even with Dinan stage 3 tune, Throttle body, CAI and headers. I'm missing 30-40HP somewhere even with the supercharger

There's a big problem considering the mods you have written and still not getting 200+ WHP :(
Did you figure it out ?
