It's been almost a month, so I thought it was time for another dyno visit! This time with 100 octane (I had 2.3ish gallons of 93 in the tank + 10 gallons of 100... so around 98-99octane total)

I've attached the graph so people who can't view embedded images at work can see it (*cough* e90AW335i)

The PROcede software was showing 15.8psi (so really 14.8psi if it was being read with a boost gauge)

on this dyno:
335xi - Stock. 93 octane: 278whp / 287wtq
335xi - PROcede V3, dual cone intake, catless. 93 octane: 366whp / 370wtq
335xi - PROcede v3, dual cone intake, catless. ~99octane: 385whp / 393wtq

Conclusion? effing badass! With a race-gas map running higher boost, there would be huge gains combined with this 100 octane.

Long story short... AWD + this power = ridiculous..... next up: DV's and a FMIC.

love it......1st gear must be unreal

Nice numbers! Question: 87% values across the board? Or did you play upwards?

+1...no boost gauge?

87%, no boost gauge, procede software reading 15.8 (so really 14.8) obviously I can't confirm that 100% without a real boost gauge... but thats how the software works and the kinks have been worked out so I am trusting it.

boost gauge will come soon

sick...cant wait to see what a race gas map will do, who knows though, maybe this BMW ECU is adjusting about as much as possible for the race gas as is, nice gains.

If the reader said 15.8 it is more than likely 15.3 or so. I personally wouldn't go any higher but it is your car.

Congrats on the results JP, very very nice!

[jpsimon]

I'd only go higher for testing the race gas map on high octane stuff.. I wouldn't run it normally

[Nick@aep]

Great numbers!! 100 octane map would be insane.

"Long story short... AWD + this power = ridiculous..... next up: DV's and a FMIC."

so what would you say, another month, new parts, then another dyno??? Nice numbers btw!!!

Makes sense. I honestly think anything about 15.5psi is risking the turbos on this car. I have information from a very credible source that confirms this as well. I will ask to see if I can share more information on this to help you guys out but trust me on this when I say over 15psi is not worth it.

[jpsimon]

ok cool! i wasn't planning on running anymore anyways.. just for a hypothetical race map that i probably wont ever actually run

[Accel Junky]

Nice results. I'm thinking you'll make about the same power with the FMIC but on 93, that way you always have that power available (I'm not a fan of race gas.)

[Mr. 5]

I just really wish that you would have taken the boost readings during the dyno run via the dyno sampling. The dyno should have a boost input, menaing that you can hook up your car to the dyno so the dyno will read boost.
This can be done by tapping into the vacuum hose going to either one of the DVs.

The great thing about doing this is that you can see the boost throughout the RPM and compare to the amount of power you're putting out.

Great numebrs!

You really need to specify RPM at a certain boost level. At 3k revs and 15 PSI boost, the cartridge RPM is lower than 10 PSI at 7k revs. I would have no issues with seeing 17 PSI at 3k revs as long as it is not held that way to redline. In this example it is not an issue with the turbos. Ancillary components may be stressed due to the increase in torque.

It would also be a downward slopping torque curve which is not BMW-like.

Blanket statements are not entirely correct and may require further scrutiny.

jpsimon, congrats on the excellent numbers.

[Driver72]

Wow
385 rwhp
393 rwtq

on an AWD car!!!

Beast I'm sure.
V3 is a strong tune that's for sure.

+1, as usual.

Good numbers jpsimon. Wait until you try the race gas map

Also, the datalogging on v3 is perfectly accurate. But since it reads from the intercooler pipe (and not the manifold like a boost gauge), it will read 0.3-1.0psi high (depending on RPM and boost pressure) at WOT. This is because it does not take into account pressure drop across the throttle body. Keep boost pressures above 5500rpm below a logged 15.5psi and you're golden. This is, of course, running proper gas.

On the race gas map, we'll run 16-17psi between 5000-6000rpm. Above 6000rpm, we'll still taper back down to ~15psi for turbo longevity/efficiency concerns.

jp did you pull any logs during your dyno runs? if so, did you log boost vs rpm?

[stillclaimndp]

damn that is massive for all wheel drive at the wheels... take it to the track soon! can't wait to see it on the race gas map. that picture is sick too by the way~!

reload, i just attached the datalog

[Sniz]

nice stable boost, looks good to me, especially on race gas.

Looks solid Ignore the bump in boost above 6700rpm. That's from the actual throttle starting to close as it approaches redline. When the throttle closes, boost builds up in the intercooler pipe, not in the intake manifold where it counts.
