Default B58 MPPSK Dyno - 07-15-2017, 11:19 AM

Hey all,

Just figured I'd share a few dyno runs completed earlier today. Mods are as follows: JB4, BMS intake, ER **, and FF wires. Running 93 octane with 2 gallons of E85.

Map 2: 404 rwhp / 458 rwtq
Map 3: 423 rwhp / 473 rwtq

The car pulls pretty strong particularly in low to mid rpms, and usually needs 3rd gear to hook completely (8-speed). Have to say though that I was expecting a bit lower numbers, particularly when it comes to torque, but I'm not complaining!

Will have to try to take it out to the strip to see what it runs in the quarter.

I'm not crazy about the power dip at ~ 3k, which you can definitely feel. Anyone know if that is common on this platform?

Numbers look good. Log the runs? That is key to any analysis. Dip looks like over boost and throttle closure. Not uncommon in a dyno spool environment.

Thanks, Terry. Here are the logs for these runs. Let me know your thoughts. Would EGW wires help here?

Yes just boost jumping over target from the long spool up, as expected. I don't see any good reason to add EWG wires here since boost is staying at target for the majority of the run.

Did you try map5? Would have been an interesting data point.

Actually, I did but map 5 didn't seem to work well for me. Even after adding some torco booster, I was seeing similar hp / lower tq vs. map 3. Attached are the dyno sheet and the associated log.

Thoughts on what could be causing this?

Yes looks about the same... The IAT/timing change is phased in over full throttle time and dynoruns are only around 6 seconds so don't capture the benefit. Makes more power at 6500rpm at least.

Yeah, good point. Have you observed noticeable seat of the pants difference between map 5 and map 3? I've yet to spend time with it on the street. In other words, smaller / equal to going from map 2 to map 3?

Some people have reported nice gains with map5 vs. map3. Curious to see more real world feedback though.

On your over boosting down low I suspect the PPK software combined with your exhaust modifications are the cause. It might be a dyno only artifact due to lower than actual load on a dynojet. If it's doing it in the real world during say 4th or 5th gear pulls you can add in the JB4 EWG connector to tune it out.

Nice. Dod you do a baseline pull to see the delta changes? When are you going to the track?

Not yet unfortunately, have been spending my free time doing road racing events.

Just started looking for one of those vbox set ups, as i think it will be easier to benchmark real world 60-130 times and impact of different maps etc.

The JB4 gives you way more tuning flexibility and potential. Ultimately, you can get more power out of a JB4 only car vs. an MPPSK only car. But the MPPSK is for sound and peace of mind with the dealer.

I run both and am happy with the combo.

I'm not understanding the first 2 questions.

You can check out my threads to see the various settings I've been running.

The Question is, does the jb4 works with MPPSK better than only MPPSK and what is the maximum HP with JB4 and MPPSK comination .. :D

Yes, the MPPSK is limited to its advertised HP. The JB4 is adjustable and its limits are much higher than the MPPSK alone. The MPPSK is limited to around 17 PSI, where the JB4 can get the boost up to around 24 PSI. Of course, you will need a lot of octane and possibly meth to go above the stock 17 PSI.
