Britalman installed, loss of power... what could it be???

montreal_bimmer · 10-01-2007, 06:44 PM

i just finished installing my Britalman intake, followed the instructions step by step....

brought the car on the first test run, and wow, its so much slower.... the car accelerates in stages.... then when you hit second, there is a huge dead spot.... so the car shifts into second gear, while accelerating hard, and the car feels like it lost traction, and it cut the power, then feels like it regained traction and all the power is applied to the wheels..... its very weird...

anyone have an idea of what it could be???

Are you sure thats not actually what's happening? DTC off might be the solution

Exhaust leak? A before and after dyno would be much more accurate than the butt dyno.

what do you mean exhaust leak.... please clarify

Andrew@ET · 10-02-2007, 02:43 AM

its an intake... anyway um just drive it around normally the ecu is learning that there is more air. make sure u put the maf sensor the right way.

wow

self!

ehhhwik · 10-02-2007, 03:43 AM

montrealbimmer, try this:

first make sure everything is connected properly in the engine bay, then disconnect the battery terminals in the back of the trunk, let it sit there for a bit, and then reconnect, go back out there and do another test drive, this allows the MAF to start out fresh, it fixed my slight laggy response on my previous gruppe m rep intake, see if it helps a bit

1clean335i · 10-02-2007, 08:30 AM

drive it a few days and let the adaptations change to adapt the new intake

Exhaust leak means that you didn't secure the piping tight enough at a location and that is causing the exhaust to 'leak' out.

thank you for explaining....

shragon · 10-02-2007, 12:40 PM

very possible it's the intake.

britalman intake is the same design as fujita (they probably get them from fujita and relabel them).

if you read up on fujita, you'll see all the disappointing responses.

imho, it's a bad intake design.

ive read the mixed reviews, and understand what you are trying to say, but if the intake is designed badly, it should still make the car go cleanly through the power band, just slower.... it shouldnt make the car choke.... and have these symptoms....

im gonna try to tighten the rings around the throttle body a little more, maybe there is air getting in somewhere....

Andrew@ET · 10-02-2007, 02:46 PM

well ive read mixed aswell.. didnt some cars stall if you did somthing on the highway or somthing?

id sell it and get the gruppe m rep for $340 shipped im so happy with mine and the power is there !

BeMyWife330i · 10-02-2007, 03:39 PM

AFE intake on ebay is $275.00 ........much better

Andrew@ET · 10-02-2007, 04:59 PM

my gruppe m rep with carbon fiber two peices with a k&n filter $290 shipped

MUCH BETTER LOL

I had an e46 330 a while back and I was playing around with my own intake. I went for a drive and my car was choking and then it stalled.
I found that I put everything together fine, but i forgot to tighten down the actual filter!

The little extra air that was coming in through the opening was affecting the MAF.
Check all of your connections once again.

scooby9 · 10-02-2007, 05:24 PM

It sounds like a flow vs. metering problem. Definitely double check all connections to ensure no leakage. Also, this may sound silly but was there anything maybe trapped in the intake or filter such as packaging for the intake?

montreal_bimmer · 10-02-2007, 05:29 PM

i checked everything out.... i tightened all the harnesses, real tight.... gonna take it for a test run after supper.... ill report back to you guys...

ksfrogman · 10-02-2007, 05:40 PM

Did you spray the filter with oil? Sometimes an excessive amount can mess up your mass flow air sensor.
