Hey guys,

We've been kicking around an N55 intake project and decided to strap the car down for a little testing. Our N55 intake design is going to be pretty nifty. 5 minuite install/removal, low cost, awesome sound, and the best flow of any N55 intake out there. We reuse the OEM airbox bottom which does a great job of insulating radiant heat and ducting flow and then remove the restrictive part (the lid) allowing our new exposed filter an ample air supply.

The test car is our 135i DCT with Stage2, BMS DP, BMS chargepipe, WW meth (50/50), BMS prototype intake, and 93 octane.

Intake gains at the stock boost levels were non-existent but at higher boost levels there was a small gain. Oddly we saw a higher delta gained on map 2 than on map 3. Perhaps some other contributing factors there. But net/net I'm confident saying we'll be able to deliver 5-10hp gains. That is simply all an aftermarket intake can add to a higher boost N55 at this point. But power gains aside I think many will find this worthwhile for the sound improvement alone.

At the higher boost levels on map 3 we ran in to more transmission slippage. Sigh. But still managed to take the N55 dyno record. I really need to put an intercooler on the car one of these days and go for 400rw.

Sweet! Let me know if you're planning on having this out as a beta. I'll get on it in a heart beat.

wow, nearly 400whp from N55...and with easy to install boltons too...

I might be trading up for a new N55 sedan so this is good news!

i need this intake and meth...i did 352hp/410tq on the dyno on map 7...needs more power lol

Sick Terry! Can't wait for a video to hear it

Question: if you could choose again, would you choose the DCT or the manual ? Or the automatic (is it available on 135i N55) ?

I will beta

Options are manual or DCT for 135i N55s. The DCT is a great daily driver transmission. It's faults don't show until you really try to get performance out of it. e.g. at the track, on the dyno, etc.

Not bad! Email me the dyno sheets if you have em would love to check em out.

yeah ill scan them and post it up and ill send you the logs too...yeah its not bad for vegas since we are 2220ft above sea level i i would think in cali it should be a lil more

Hey Terry, do you think the twin clutch from the M3 DCT or F10 M5 will fit the 135?
Car...tranny......twin-clutch
M5 GS7D36BG ????
M3 GS7D36SG 28407842841
135 GS7D36SG 28407842841

As you can see the M3 has the same tranny and clutch. Although the M3 bell housing is different the clutch is the same. The M3 has over 400hp but the 135's clutch slips at 400hp. Also the software is different in the M3 letting it roll like a manual.

time for an SSP upgrade in that trans Terry
