Love that torque curve!

I believe Alpine 1's JB4 went bad so this is likely a stand alone BEF tune.

I would also like to know the boost level being reached, octane used, and Auto or Manual.

[Seaneezy]

Please give more details on the build? No way those turbos give 140 over stock

Hello,

Here are my mods ST adjustable coilovers
Forge hard pipe & Forge BOV
BMS cone filters
BMS down *****
Fuel it stage 2 LPFP
Active Autowerkes intercooler
Agency Power exhaust
BMS Oil catch can
RB Turbo next gens
P3 boost gauge
Alpina transmission flash
A lot of cool coding done.

The car is an auto w/ the Alpina transmission flash. No JB4. 93 octane.


This is from Bimmer Performance Center (BPC).

All Your Boost is sitting at 21 PSI tappering down to 18 at redline. Timing is 12 degrees across the board. AFR was clean and steady throughout the entire pull.

[Rob@RBTurbo]

Not bad numbers for 93 and great overall power band. OP was told his HPFP was diving despite having a Stage 2 LPFP, which seems a bit off but he may have a dying HPFP. OP also reported he is seeing around 16psi on his P3 boost gauge, not sure if that is still the case. Also the numbers are in SAE but not sure what difference STD would've yielded for him. Attached is a full dynochart that he had emailed.

[Alpine1]

Thanks Rob. Your the damn man!!!! Thanks for everything.

Interesting, another recent dyno rb next gen plus turbos were 489hp and 440tq.

50 more hp and 50 less tq than the std next gen. Is that to be expected?

My next gen plus turbos showed up last night and I cant wait to get my car back on the road and enjoy them. Congrats Alpine1 bet that car is fun to roll on the gas at highway speeds

I think those turbos are able to put 500whp with hybrid e85 custom tune

[Alpine1]

From what I understand if I replace my HPFP i will be at 500hp & if I get a E85 tune I would start making some real power.

You can’t take two dyno charts from different dynos in different places on different cars and use the delta as an absolute number. That’s just not fair

I get that, I was just surprised the curve was greater for tq than hp.

After I posted here, I was able to find the post where Rob at RB shared multiple next gen dyno plots to see other next gen HP and TQ curves. I would love to see this car dyno again with a new HPFP and inlets (if it doesn't already have them)

[bnk]

What is the red curve?

[Alpine1]

Yes I have the inlets. You buy them when you replace the turbos

Is this the mod list for the run with the higher power? What are the mod and tune specs for the red/orange curve run?

[Alpine1]

I would have to think that was before the tune. I didn’t ask when I picked it up. They ran into some troubles when making the tune. They had to replace my old charge pipe & BOV. They replaced w/ Forge hardpipe & Forge BOV. They replaced my injectors w/ index 13 what ever that means. If I want to make better power they recommend to have my HPFP replaced. I missed my window w/ BMW. I didn’t realize that I could of had it replaced if I would of just asked. Today is 74degrees & my P3 reads zero to sixty 3.66 & zero to one hundred 8.79. The car drives & feels totally different since I had the JB4 removed. Major thanks to the hero’s out there who pulled their capes out of their underwear recommended the tune over replacing the JB4.

[JuniorB]

Bpc are doing big things with Bmw turbo engines. Have you looked at the m5 they just put a pair of Efr turbos on? There almost at the 1k whp mark. That's serious power for a stock engine! In a 4 door!

[bnk]

So red/orange is likely with JB4.

[Alpine1]

I had the JB4 removed before taking my car to BPC.

[Alpine1]

I had the JB4 removed after the new turbos were installed. I had the BPC tune put on my car about two weeks later. Back in Feb 2016 BPC dynoed my car w/ the JB4 on it
& it was 355horse & 385 tq. I would have to think the red numbers were my mods only before the tune was put on.

[bnk]

Did you have BEF? Even if JB4 was removed, BEF could be left there. How much WHP is BEF worth without JB4?

[Alpine1]

I’ll call BPC in the morning. I do remember BOB from BPC telling me that there was a BEF on the car when he hooked up his computer. All the mods were on the car when I bought it except for the intercooler, exhaust & oil catch can.

[Alpine1]

I just called BPC. Yes the base line was w/ the Back end Flash. They removed it before they made their tune.
