In regards to the upgrade you linked, the internals should be fine. However the cars wiring harness is suspected to be the limiting factor. Ill look for the facebook group discussion, but because we can definitively know what gauge a wire needs to be to carry a certain amount of current safely, we can determine if the factory wiring would be sufficiently thick enough to carry the extra load. The analysis on Facebook showed it wasn't thick enough to carry all the extra load the new module would allow.

This is much different than pushing an engine harder for instance, because you know that if you tune an engine carefully and avoid knock and lugging on it. Then you can effectively avoid events that would cause an engine to fail. With wiring that's not possible, the current will flow through it and the wire will hold it or it won't.


Also the stock drive train components have massive amounts of head room on it vs. the wiring, because there's incentive to make engine parts stronger so it can be used on more platforms. For instance the m2 shares the s55 rods, piston rings etc. Whereas the with wiring, there's not a massive incentive to make the wires super thick, because stock fuel flow even for highly tuned factory variants will never pull as much power as the crazy after market options we are looking at.

*takes a deep breath*

You’re not my read dad F87Source, you can’t tell me what to do.

Can't find the Facebook posts anymore, but here are some nice spool street threads to read:

The instructions from et3 also says the factory wiring is near it's limits and should be upgraded if you want to push more power.

Which lpfp are people running? I understand the EKP modules aren't easy to come by and there might be one that doesn't need it..

Honestly curious if the fan does anything if you keep the side cover closed off? According to ET3 Design, their installation manual states:

Try to ensure that the EKPM3 has some airflow around it and can get fresh air from the surrounding area. This
may require some modifications to the plastic and cloth coverings. Only a small amount of air exchange is
needed.

https://et3design.com/installation%2...ctions_2_2.pdf

That would be a no go for me unless there is a way to get air in there in a non-visible manner. Beefing up the internals (larger gauge wires, heat sinks, etc.) to handle the current does seem like a better solution to me (which the ET3 Design EKP does to some extent).

Alternatively... I imagine the only time the EKP really gets hot is under continuous load, I could just pop off the side cover when I head to the track. For street driving, I doubt the lack of air should pose a problem if you do pulls here and there. Still, not a pleasant thought if I forget to do so I'll have my car needing to be towed due to all the connectors melting.

Curious for those running PS2's and similar. I am experiencing high WGDC %. Fixed a boost leak, but it did not change the duty cycle/boost much at all. Expected it to drop quite a bit. Its getting to 19lbs targeting 20, but wgdc is still high around 90+%...Expected it to drop into the 80's after the fix...anything else I should look at thats not obvious? Thinking maybe wastegate % is not actual since not factory turbo(?) 70% doesn't actually mean its 70%(?)

Modification list?
Any inlet? What intercooler?

[VGSON]

The general stage 2 items.
200 cell downpipe, FTP inlet(v2) and outlet, ER chargepipe, VRSF 5" intercooler, Drop in dry filter. Dorche stage 2 fp. Turboosmart plumback...

[AmuroRay]

The only thing I see that can potentially be an issue is the size of the intercooler and MAYBE the DP (but that shouldn’t be a WGDC issue…), but I don’t know if I believe that myself. Are you sure there isn’t a leak? Have you compared logs to anyone else on what their WGDC is at the same PSI?

Can't find any pure750 logs since its new. Been find some sparse ps2 logs, but most are pwg and not ewg. Even tried looking for pure800 (b58) logs since its a similar turbo and manifold. The PS2's seem to running less duty cycle if I'm reading it right. Pure seemed to indicate the duty cycle would appear high. "One of the caveats of EWG". The shop who installed the turbo ran a leak test and resolved one big one, said there's another VERY tiny one at really high boost. They couldn't tell me what PSI they ran it to, so I'm doing it myself with an air compressor to verify. Just seemed like duty cycle should have dropped significantly if they did fix a big leak.

We're also going to turn it up some to see if we're just being too conservative(?). It currently breaks traction at the top of 2nd and pulls hard in third at 19/20lbs. Then the dyno in the next week or so to really turn it up. Get the power coming in earlier and turned up more.

Yeah Im going through some issues too trying to get my Pure 750 boosting. Currently on my second revision and I have the car all back apart. Tune is targeting 22 psi and Im missing it by 2 psi and then it starts to fall off. I come closest to my target around 4400rpm. My tuner thinks I have a pretty big boost leak. Only thing I was able to find is my turbosmart blow off valve was leaking at the side openings. It wasnt huge but it was enough to make bubbles with soapy water. Im gonna contact turbosmart tomorrow.

Im also gonna contact Evolution Racewerks as I have their one intercooler piping for my F10 intercooler to charge pipe but Im hoping they have the boost tube too. Right now Im using the FTP one and its the biggest POS Ive ever had to use.

I have some logs I can share tomorrow. I also had someone from Germany contact me asking about my turbo as he also has one and is struggling with building boost and putting down power. Hes already had it on the dyno and sent
me the graph so maybe I can share that too.

Also maybe you can tell me when you do your boost leak check where yours are coming from and what your turbosmart does leakage wise. I see leakage coming from between my inlet and turbo but thats on the vacuum side so that doesnt matter.

It’s your inlet - on the F10 it’s just too small and restrictive, and it will limit your airflow at anything above 5-5500rpm. The FTP one likely isn’t really doing much better than stock

My turbo inlet is the Pure billet inlet and its a 3” billet inlet with a full 3” custom intake that goes all the way to the front/ grill of my car. I will be offering this for sale when I launch my online store with In house performance soon. Getting it powdercoated with Maf option and with flanges for your pcv heater valve and pcv hose.

Heres my last log before I started investigating my boost leak Have to order some parts today so hopefully have it running by this weekend again. https://bootmod3.net/log?id=646194f3c090c63403eb801e

Massive boost leak, a few guys on the F30 side are at 22psi at 3700rpm

[InHousePerformance]

Yeah I have a few ideas Im gonna work on and some new parts and hopefully get a new blowoff valve and hope that fixes it.

Can you post a picture of your inlet? A few F10 guys are having issues with maxing out the stock inlet, it’s a terrible design.

[InHousePerformance]

This is a pic of Pures Billet inlet and then a pic of it on the car. Unfortutnaly Its currently at the powdercoater but this was what it looked like on the car with out the flanges welded on. Ill have pictures of the kit once its done. Hopefully in the next 2 weeks. 3 inch is a pain in the a$$ to get into that space but I was able to do it with the right bend.

Mine was leaking from the TMAP port. The oring on the 3.5bar was too small for the opening. Then there's another at the intercooler to charge pipe connection/area Im tracing down...Need to get it pressurized and in the air to see exactly where from. At the silicon connection or where it connects to the intercooler. When the shop did a leak test, those were the spots. They didn't indicate the turbosmart leaked. BUT thats why im rechecking everything again.

Planning to pressurize past 25psi and see. They used a smoke machine

the FTP is a copy of the old PS2 inlet and not much different than the others..At least the V2. Those were hitting 550+ wheel...Would love to have definitive data of the above though.

On an F10? Are you sure? I admit I’m not 100% familiar with them, but that wasn’t what I was seeing. I hope I’m wrong

amuro, Im referring to the f87 platform and aftermarket inlets.

Ive read thru scottygrapes thread. He’s got the new pure setup on his, billet adapter. He may have a custom setup though as his silicon piece wasn’t correctly made. I have the ftp v2 on mine..Hopefully once the leak is sorted and final tuning is done I can see if this inlet is an issue.
