1) As I remember, two forum members already posted their dyno results (380whp) of dinan turbo kit. Coupled with hi flo dp and turbo inlet, dinan kit seems to net 50whp or so on top of stock m2, something that I don't think is achievable with stock turbo and similar bolt-ons on piggyback especially the conservative Dinan. 2) Not offering a stg1 turbo for m2, Pure could have gone public that m2 turbo is a PS1 equivalence if that's what they found out true. It works perfectly in their favor and against Dinan, the only turbo competitor in the m2 market. 3) From our numerous tests and JB4 data logs on multiple m2s and 35is, EWG PS1 turbo flows better than m2. With adequate cooling (not necessarily with meth), PS1 holds 16psi at 7k rpm on pump gas easily, where m2 sees 14-15psi at best, provided piggyback is properly configured. In full disclosure, we saw boost held slightly better with m2 than other stock n55 EWG turbos. That's because, to our limited knowledge, m2 DME with higher load targets out of factory acts as a BEF so the system works with closer values to stock and thus is better at controlling variables.

2) True, You're right 3) I've seen personally M2 holding 16-18psi at redline but that doens't mean its good nor that is making more power either.

DP gets about 10-20 HP depending on the model. DP, FMIC and air filter with 98ron gives just over 400-410HP or 335-345 WHP. The IC made the biggest gain. It would appear the down fall of this engine in the M2 is heat. IC allow you to hold timing for much longer. I've seen a car with the above mods + MPE and hard induction/turbo hoses make 430ish HP, a little over 350WHP Only way to get 400 WHP will be with a hybrid turbo and ecu remap. |

So I have just been reading mostly and not chipped in just trying to learn as much as I can.
I dyno's the car on a 90+ degree day in Florida. Mods at that moment were the Fabspeed Sport Cat Downpipe and the Bypass exhaust. I have changed up that setup since then. But my numbers on the Dynojet were 358whp and 407tq. Next mod will be an intercooler upgrade and will dyno with my new exhaust setup which replaced the Fabspeed Bypass with the Resonator Delete and Free Flow Exhaust from DINAN.

Catless DP adds 10whp or so on stock m2/235i, think 10 at best with a high flow. Anything beyond that should come from mouth of seller. It'd be a different story when boost cranked up though. And IC does nothing for peak power before heat soak which you're less prone to with stock tune. You will see a cooler IAT for sure but that should come with a lower boost from DME adjustment to preset load target, power will be made the same. That being said, you probably WILL see higher numbers only because of bigger STD/SAE correction factor applied (again, double effort with modern turbo engine) as weather is getting hotter.

I figured the FMIC would not show an increase in power on stock tune, I'm mostly looking to battle heat sink issues I know I will most likely experience on a full track in FL weather. After FMIC and maaaaybe Intake (still debating since I understand stock one is very efficient) I will decide on which tuning platform to go with. My goal in not peak numbers, more interested in usable power in the midrange while still smooth as stock.

Care to clarify: Is 373 an uncorrected number? Are you referring to 466whp as a STD/SAE corrected number or a crank hp calculation assuming a 20% drivetrain loss? Congrats on your great build!

373 is the uncorrected number. As stated on the bottom of the graph sheet, divide by .80 for crank numbers (20% loss).

Is it truly less than 20whp that your butt dyno says jumping to P2? I'm not being hard, I am only serious when it comes to telling true and false on power delivery.
