BMW E46 330 ZHP and Non ZHP Dyno graphs.

What about your dyno with the aFe? I can post mine here if you want.

Please post yours.

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.

You have AFE correct? Oiled or dry?

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.

OK...thanks

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.

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!
