BMW 1M time attack car

After slowly getting work done and just doing repairs on my 2011 BMW 1M I finally got some more room to get some upgrades!

KW clubsports v2
BBS RIA 10.5 et22 squared from (@slicer_m) on Instagram
265 Squared at the moment will go up to 275 or 285 squared when the tire is available.
Nankang AR-1
Racetech 4009 seat
CAE shifter
PFC 08 pads
active autowerke intercooler
VRSF downpipes
Active autowerke Catback exhaust
Dinan stage 2 tune



Went to WSIR for my second time and ran a 1:33
Also went to streets of willow for the second time and ran a 1:27
still learning the line on both tracks.
it was about 90 degrees on both days, had little overheating issues after about 8-10 laps but one cool-down lap made it all go away.
besides of course going to the track more for seat time new mods to the 1M soon.

IF anyone is in SO-CAl
contact slicer for wheels
and JMP Autoworks for any work on their cars.
both are amazing to work with.

295 squared a052's
stoptech st40 355 bbk
PFC 08 pads
Castrol srf fluid
CSF radiator
KMP wheel
Recaro spg xl X2
Custom cage from @michael_cox on Instagram he is the cage builder for trinity autosport, he does the best cages in CA.
One of my newest mods yet to come in is new turbos from Hydra performance, running the 650 set excited to test at big willow on the 17th of april.

installed the hydra performance turbos was tuned via MHD by wedge performance, Ken was amazing to deal with helped answer all my questions and got my car running 425 whp and 430 wheel torque. tested it at big willow a couple of days ago and run a 1:31 with only two or three hot laps. I cannot say enough good things about the turbos and the tune.

excited to go back to buttonwillow cw13 for a 54 or 55 with this new power setup before I throw some aero on the car.

The car has power steering issues, with it boiling over and now running an overflow for the power steering and now the pump going out if anyone has dealt with this let me know how to fix it. I know running 295 squared probably doesn't help but it drives so nice.

Nice build. Doing something similar perhaps.

How are those turbos compared to stock (Mostly concerned about turbo Lag). Any difference?

Also, I hear the CSF radiator leaves no room for an aftermarket inlet (with stock positions). Did you find the same issue or did you relocate your inlets.

Can you please post details and photos of the overflow for your PS reservoir?

I thought the 1M PS reservoir would resolve the 135i/M3 PS reservoir issues (where fluid leaks out of the top breather hole) but it doesn't.

I don't know if you have seen this, but it may address your issue...

Yes, I've seen that thread and quite a few similar ones but they all have a 135i or M3 PS reservoir and tap the cap to connect an small overflow reservoir. The 1M PS reservoir is a different design and was supposed to prevent overflow and spray but it doesn't, so I was interested in whether the OP had implemented a similar or different solution and how it was done.

As I run 295 squared I have had a couple of issues of blowing my powersteering. my shop through of a couple ways to fix the overflowing issue and came up with this.

Interesting, two 1M reservoirs. Does the secondary reservoir have a fluid pickup that extends to the bottom of the reservoir and, if so, how can you guarantee that it will pickup the fluid to return to the primary reservoir? Otherwise, how does it return the fluid to the primary reservoir? What happens with the outlet on the bottom of the secondary reservoir - is it blocked off or routed somewhere?


Here's an example of the M3 reservoir with an overflow (BMW F650GS motorcycle rear brake fluid reservoir).
Notice how the PS overflow is routed into the bottom of the motorcycle reservoir, which means that the fluid just flows from back down into the PS reservoir when the pressure subsides.
I'm thinking the bottom of the overflow reservoir should be mounted higher than the top of the PS reservoir so the fluid is gravity-fed back to the PS reservoir.

* 2 feet of (4mm?) vaccum line (Napa)
* 90° fitting is a 5/32" elbow connector PN#9873 (Napa)
* 1 M6 bolt (+ M6 washer)

Total cost: less than $40.

Notice the logo on the cap? Yup, Brembo!

Also notice the nipple on the cap is angled so it fits perfectly bolted to the ground bolt thingy on the side of the engine bay without bending the line.

I used a little under 2 feet of line just so I can unscrew/screw the cap without disconnecting anything.

I'll find out next weekend if this setup works as expected.

Aus: the bolt I just found in my box of misc random hardware. Any bmw bolt with a 10mm head should work provided it's not too long.
