Cts turbo f-series bmw n55 boss turbo upgrade

135 TING · 02-07-2023, 09:51 PM

Update: needed new tires installed, and now I’m in search of a boost leak

Eschmacher · 02-27-2023, 10:29 AM

You ever find the boost leak?

135 TING · 02-28-2023, 10:26 AM

Update:
Found the boost leak, but need to get the wastegate calibrated now.

atek · 03-03-2023, 11:03 PM

in for updates

AmuroRay · 03-07-2023, 02:14 PM

Updates?

135 TING · 03-17-2023, 12:53 PM

Sorry for the lack of updates, I’ve been chasing down a boost leak and a coolant leak
And I’ve been swamped at work will try and find sometime to get all this done

Steventalon1 · 03-22-2023, 09:38 PM

I am interested in some updates as well. I am wanting to do a upgrade from the stage 2 in the future.

This is with the CTS turbo? That takes a while for boost to come in, how does it feel?

Ya, thats with the CTS turbo. It pulls pretty good, can't wait to get it custom tuned. I did get a leak on the braided line, the dark stop at the crimp. They had to take the turbo back out to get to it.

Thanks for taking the time to share this information, I'm also interested in this turbo but there are conflicting information on the forum

TheSandman_M2 · 05-07-2023, 06:33 PM

Conflicting information?

Hi Sandman compliments for your ride!! Reading your mod list made me

By conflicting information i mean that on the initial post of this turbo in the forum people started to question the dynographs shared and it seems no one is managing to give dyno results on full boost with this turbo.

As you can also see on your first log it takes more than 15 seconds to reach boost target.

TheSandman_M2 · 05-09-2023, 08:59 PM

Thanks, I think I have a mod addiction problem. Looks like I start it at 3200 RPM and reach target at 3900 RPM. I think that's pretty good, 4th gear. On the other one, 3rd gear, I start it at 2900 RPM and reach target at 4100 RPM. It may have spooled faster if I started at 3200-3400 RPM. Not sure how you get 15 secs to reach target? I'll get more logs when I get it back. I only got the two before I noticed the oil leak.

If you look at my dragy time you'll notice my awesome 60ft. It was spinning pretty good, need to lower my tire pressure. But what's really crazy is the 126 mph, so the cars moving pretty good even with the shitty 60 ft.

Here's the same car, same map, VTT GC+

spool time is comparable to a PS2, looks like this may make slightly more power from your results.

Do you have a IG? You're somewhat local to me, I'd like to check out the car.

Dee235 · 05-22-2023, 05:51 PM

Im having fitment issues with my kit in my car. Did anyone else have to fabricate anything or move lines out the way?

TheSandman_M2 · 05-22-2023, 07:42 PM

They reinforced my manifold, they seem to have a problem cracking. Then the lines are a little tricky, what thay said about my install.

jb-slow · 05-22-2023, 10:38 PM

Garbage manifolds, sweet.

Dee235 · 05-23-2023, 06:16 AM

Yea I’m having issues with the lines what did your guy do to get them to work? My mechanic had to heat up one of the oil lines and bend it and the water lines are just not working out.

I'm not sure if they fixed the problem on not. The cracks may be on older manifolds and if they say they've updated them, they admit there's a problem. My installer has seen three or four cracked manifolds now. He's putting the same turbo in his car though, with it reinforced.

Dee235 · 07-24-2023, 07:39 AM

Definitely reinforce the manifold if you plan on using this turbo.

TheSandman_M2 · 07-24-2023, 11:53 AM

Man, didn't you just put it in?
