Garage List
2011 BMW 135i  [10.00]
N55 Vargas Stage 2 DBB Turbo Pump Gas Dyno

Note: This is a low reading dyno dynamics dyno, don’t just look at the final number LOOK AT THE DELTA!

So PTF finished my pump gas map and I had a chance to chuck the car on the dyno.

This is the same dyno I used when stock and after my first round of power mods so you can see a good comparison.

Car is a 2011 DCT 135i

Red Line: 230whp/260wtq
Fuel: 100ron with 10% ethanol (94 in the US)
Bone Stock

Green Line: 300whp/375wtq
Fuel: 100ron with 10% ethanol (94 in the US)
JB4 on Map 5
ER intercooler and charge pipe
K&N Filter
BMS downpipe
Custom resonated 2.5” midpipes
Magnaflow muffler

Blue Line: 350whp/362wtq
Fuel: 98ron (93 in the US)
As above plus
PTF protune instead of JB4
Vargas Stage 2 Dual Ball Bearing Turbo
3” muffler delete
Walbro 465 in tank low pressure fuel pump



Most impressive is the difference above 5000rpm, the stock turbo falls off hard but the Vargas holds strong until after 6500rpm.
So even though Tony says there’s not much point using his turbo with normal pump gas obviously that’s not the case. You will definitely see better gains with E85 and that is my next step.

Few pics, video and datalogs included.
