I'm about to take delivery of '17 M2 and I'm keen to get started on the mods. Car will probably never be tracked and will only be driven hard in short bursts as opposed to prolonged sessions (cops in Australia are ruthless). I'll be doing decat DP, intercooler + charge pipe and BM3 stage 2 93oct/98ron tune with no other mods planned.

I know 6 inch intercoolers are usually recommended for those mods but due to the lack of track work and nature of driving will a stepped 5 inch intercooler be suitable? Don't really want to go bigger and introduce unnecessary lag if I can avoid it.

Thanks

the 5" upgrade will be a major improvement over stock, so if you are asking if you can run it with your mods the answer is yes you can.

It will not perform as well as the the 6" even for short street pulls, all it takes is one pull for the temps to go up.

If your car is FBO you will not notice any lag with the 6" intercooler.

Mike, what would you suggest for my situation:

- 2017 M2 6MT (N55)
- Akra 300 CEL Sport Cat DP
- Akra Exhaust (planned)
- BMS charge pipe (planned)
- DV+ (planned)
- No tune planned
- Stock intake
- Driven hard, incl hard canyon runs, occasional track day

I like the Wagner product line because it comes in black.

Thoughts?

I run the Wagner Evo2 Competition and don't notice a difference in lag between Stock, Stg1, or Stg2 tunes.

Hi Mike,

When you say there will be no lag with FBO, please can you clarify if you mean FBO without a tune, or FBO with a tune?

Cheers.

Definitely with tune ... If you do not have a tune you should get a 5" intercooler

WideT,

If you are concerned about lag due to upgraded FMIC, I can recommend - 1st hand - adding Pure or FTP hi flo inlet pipe [removes a restriction on the inlet side of the turbo] to offset the lag.

Works very well, provided you are choosing the right FMIC ie one with low pressure losses between inlet and outlet.

FWIW, I had Wagner Comp Evo II on my stg 2 JB4'd M135i and will be fitting CSF to my BM3'd M2.

Anyone here running a LCI DCT M2 with a JB4 and Wagner Evo2 Comp IC as the only mods? I would like to know what Map you are using with 98 RON fuel

If using stock DP, I'd stick with map 1 or try autotuning map 5.

If you datalog both and see/feel some good gains with map 5 vs map 1, then use map 5 datalogs to create a custom map [map 6].

FWIW, I'd suggest upgrade stock DP to either a decat of 200CPI HFC DP to get most out of yr JB4 on yr m2.

Hi BP,

I was only talking about this part with a friend yesterday as I was unsure how much benefit would really be realised without a bigger turbo. Was you experience with the hi flo turbo inlet based on a stock or already tuned car?

I'm very interested in anything that minimised turbo lag.

Cheers.

Re IAT's - obviously the lower the better, but is there a temperature range that is usually aimed for?

Also, what would be the max temps seen before an engine started protecting itself?

+1 I really like to hear this as well because I'm thinking either use FTP's Inlet pipe or Pure Turbo(with bigger size than stock) if I stay in the stock turbo.

M2 stock inlet pipe is same part as fitted to early F2x m135i and F3x 335i with PWG turbo. Inlet ID is ideal for smaller PWG turbo compressor wheel. The later EWG turbo - as fitted to m2 - has larger comp wheel hence oem inlet pipe is restrictive by default.

On my JB4 tuned EWG n55 in my m135i - the Pure hi Flo inlet pipe helped the car to punch harder longer higher up the rev range. Areas under power and torque curves grew by about 20 & 30% respectively. No brainer imho for n55 in my m2.

I'm more interested in the ER, VSFR and CF (ATM?) products.
