Dyno'd my CP downpipe m5

[TrevorM3]

1800 miles, downpipe only, CP, car put down 550 wheel.



no graph, maybe if i'm not lazy i'll post a video sooner or later lol

Great numbers bud! That's pretty accurate and on par from what I have seen. Downpipes worth about 10-15hp on a stock car.

[allmotor_2000]

Good power - crazy how underrated this platform comes from the factory. Conservativeley that's 650hp

What are the typical drivetrain losses on our cars? I've read anywhere from 10-15%

Trevor, interested to hear if your car has been jittery at all since your DP install.

I installed my RK downpipes about 3 weeks ago and for the first week or 2 it was perfect! Now the car is a little sluggish, shifting at weird times/holding gears to long. It almost feels the ECU is confused and restricting boost or power.

Anyone else experienced this?

thanks mike!

Yeah I have CEL, but I'm assuming it's just because of the missing CATS. It's probably time to invest in a scanning tool.

The more I drive it I think Mike is right...probably time for that BPM tune.

[TrevorM3]

Shit yea.. that makes sense loll.


Doing BPM tune soon also

[Bimmma]

Trevor, when are you planning to do your tune?

I have the same RK DP and had it installed for about 3-4 weeks now, car runs fine and strong..I'm running JB4 stage 1 though.

i finally have a spot open in my shop, so i'll be putting it on my framerack for downtime,. i think next week is the week.

Lerxst, you won't be disappointed. Did you go with Stage I or II?

Hey Bimma, I stayed with stage 1.

I dyno'd at 545whp / 545wtq (completely bone stock) a couple weeks ago and I'm curious to see what just the tune gives me.

I did install my AWE Touring exhaust last week but I doubt that will do much for power - it just sounds really good!

Lerxst, interested to see you numbers with stage 1. It sounds like our cars are pretty similar.

I've got:
Awe exhaust (love this freaking thing!)
RK catless downpipes
BMS intake
And just shipped my DME's to BPM for stage 2 tune.

Interested to see how the numbers will compare.

[Leec33]

let us know numbers ASAP!!!!!
