Dyno Expectations

RX-BMW · 06-05-2014, 09:43 AM

Hey guys,

I have an 09 135i coupe 6AT with following mods:
COBB stage 2+ tune
AR catless downpipes
Berk street axleback
DCI air intake cones
ETS 5 Intercooler
Alpina B3 transmission tune
stock chargepipe

Heading to get a car dyno tomorrow, what should my horsepower expectations be? This way I will know if there is a boost leak somewhere.

Thanks!

I'm not sure but I would assume above 350rwhp.

Do you assume you have a boost leak? I'm sure when you look at the dyno chart afterwards you can tell if it's leaking boost or you could do a couple of logs and let some people on the forum check your stuff.

vivanapoli806 · 06-05-2014, 10:36 AM

It depends on the dyno they all read different. U should be over 350 at wheels. I put down 350 with cobb stage 1 aggressive and dci with oem down pipes

Zombie1 · 06-05-2014, 10:40 AM

380whp give or take

350whp if you're on pump gas.

You're gonna need a chargepipe soon... I would get one asap honestly. Blowing up the stocker is a pain in the ass

+1

As for dyno, you probably want to run the cobb map and then compare it to stock.
Since every dyno reads different just looking at cobb stage 2 numbers will not ,mean much.
Also keep in mind its hot out there so your numbers might be lower that expected.

Lmaiuri · 06-05-2014, 12:14 PM

+1 on the charge pipe. It was the bane of my existence before I went with an aftermarket pipe with the Tial BOV. Most likely you'll leak boost from the DV's. Throw a couple gals of e85 in and get the COBB e85 map for the dyno.

RX-BMW · 06-05-2014, 12:52 PM

Thanks everyone. Reason I suspect a leak is due to poor 1/4 mile time at the track a couple weeks back. 13.46 @ 107mph was my best. Granted i had awful 60' time of 2.2 seconds
Tires: Bridgestone Potenza 760 50% tread.

Suggestions on Charge Pipe? Is this a fairly easy DIY? The intercooler was a pain but still got it done with a friend's help.

Any aftermarket will do the job. Extremely easy to install. Get one with the oem style C clip on the throttle body side to make it easier

RX-BMW · 06-05-2014, 12:54 PM

Pump 93 octane fuel and Stage 2+ COBB (aggressive) tune

Depends on if u want diverter or bov. If u want bov vrsf is best priced charge pipe. I got black one with tial bov. Couldn't be happier.

RX-BMW · 06-07-2014, 09:19 AM

Came back 341hp. They couldn't do RPM wiring so no torque numbers.

BEAR-AvHistory · 06-07-2014, 10:19 AM

^^^^ typically you need to bring a hex key to lift the engine cover.

RX-BMW · 06-07-2014, 10:39 AM

Yeah that's what they said they would have to do. I also couldn't stay in 4th gear for the life of me, the dyno chart is full of oscillations.

BEAR-AvHistory · 06-07-2014, 01:14 PM

^^^^ I posted how to make a stop that will keep you out of kick down, might be on this site. If a search does not show it let me know & I will cross post it.

berne · 06-16-2014, 11:57 AM

i think he has a pretty nice setup:

COBB stage 2+ tune
AR catless downpipes
Berk street axleback
DCI air intake cones
ETS 5 Intercooler
Alpina B3 transmission tune
stock chargepipe

and what can he swap to get like 400whp? or dose he have to swap the turbo?

vivanapoli806 · 06-16-2014, 12:13 PM

I think with stage 2+ aggressive and some meth he should be able to hit 400 at the wheels

RX-BMW · 06-17-2014, 12:11 PM

Is it worth it going to a shop to test for boost leak? The one I called last week said I would FOR SURE know if I had a leak somewhere (doesnt seem obvious to me as car still feels powerful)

RnmEvo9 · 06-17-2014, 06:04 PM

I'm fairly certain you have a boost leak. You should be running a lot faster with those mods. This is what I ran with just Cobb Stage 2+ aggressive, Helix FMIC and Raceland downpipes on 93 octane several years ago: http://www.1addicts.com/forums/showp...86&postcount=1
