M6 Dyno (BMS + Akrapovic + AMS downpipes + Charcoal delete + PedalBox)

[mr-karim]

So I dynoed my car. The car did show over 600WHP with no problems, but after 6000rpm a computer in my car started thinking that it was doing a burnout, therefore it didn't spin any further (fuel cut early).
To get an exact number, I'll have to bring it to AWD dyno... Estimate is 650WHP.

Yes the traction control was off.
I am using 94 octane.

Charts: (1tun with pedalbox off, 2 runs with pedalbox on)

Maybe, maybe not. LSM dyno didn't show really a single pony past 6200

I'll try Dynojet too.

Nice. now you must be very careful to drive this monster in Canada My car is stock and I feel side skidding every time I drive in california with MDM mode.
I think no more mod for you Mr-Karim it's more than enough

Ya man, too bad I couldn't get an exact number
But it's still a little higher number than Manhart's 700hp crank m6, and that thing dominates; overall, I'm pretty happy.

I'll show off some new stuff I got installed yesterday, very soon

[SlashM3]

I'm curious cause lsm dynoed 589 with just bms and charcoal filters removed. That ams DownPipe is only giving 20whp?

Basically dyno showed over 600whp, but didn't show an exact number...
I'll use a different dyno soon. I'm pretty happy with the result.

[SlashM3]

I would to.

if the flow is going to help anywhere its going to help up top, lets wait and see what the dynojet says

Correct. We need a real tune.

With that torque curve there's no way your making any more power after 6k . All of those runs show right at 600 whp , with a very ugly torque/ power curve in the midrange and tq dropping really fast up top . You're ECU does not like the BMS , it appears to be almost instantly reducing any gains after 4k rpm. When you Dyno it again run it with the BMS off too . Thanks for posting .

ECU is still adapting to the boost, I made a few changes in my BMS box, played around with PSI.

We'll def turn the boost down , that curve looks like you were having severe knock . I would suspect that the ECU was shutting your runs down to protect itself . Terry isn't going to pay for you're new engine .

[gmd2003]

What psi were you running it on for the Dyno session ?

+3 PSI over stock, should be ok with modded parts and 94 race gas

It wasn't ok trust me you're car was knocking like crazy and pulling a ton of timing on those runs you showed . Don't do it anymore please , you're engine is crying .

PP-performance uses about 3PSI over stock, runs ok.
My fuel consumption improved well after installing bms and the pedalbox, way better I'd say.
For now BMS is the only good option, let's see what Dinan offers something any time soon.

By the way, check this out


M5 with BMS tune and stock parts.

It's you're car and it's not running well on those settings . By the way my M6 CP package was faster than that pp car 60-130 when I was bone stock at 8.09sec. I'm serious about you're engine being at risk ,turn it back to the base settings , you will make more power too.

Did you Dyno your car sir?

Nope , just tons of Gps data logging , stock then after each mod . Essentially adding SS catted DP,s and intake dropped .2 seconds off my avg 60-130 from 8.1 to 7.9 sec , cut .2 seconds off my 1/4 mike ET from 11.6 to 11.4 and increased my 1/4 mile gps speed from 127 to 128.5 . I would only Dyno mine if I changed my tune to ensure it made more power / was safe. Right now there is nothing better than the CP tune .

[gmd2003]

Look at this bone stock CP graph on 91 octane . That's a nice power curve , making more power all the way to over 7k . It's actually making more tq and hp than your car in the midrange where you had the most knock . Different dynos so the absolute numbers don't mean as much as the shape and nature of the power curve.

Good numbers. I bought the vBox for myself, should receive it on monday.
Why don't you dyno your car? Costs about $125 for 3 runs.
