Hi guys,
Just got back from our 3rd dyno tuning session. So far, our single turbo system tuning sessions is coming along quite nicely. Today we returned to the same dyno we used a few days ago when we put down 585whp. Still running 94oct pump plus PWM Methanol. This time, we removed the 20psi boost limit that handicapped us before. And with boost at 16psi at 4000RPM tapering upwards to 22.5psi by 6500rpm, it put down this without any muss or fuss:



And video. Sounds awesome. Funny how the front end of the car lifts up


We only did 3 pump+meth runs today. The first two ran a peak of 21psi and made 600-602whp at 20-21psi peak boost. By just adding another 1.5psi up top, it picked up another 25WHP. Pretty astonishing how much power the car is picking up with with incremental changes in boost pressure now that the turbo is operating at it's sweet spot. The turbo itself should still have another ~100hp left in it

So far, fuel system is well within its limits. Fuel trims aren't even closed to being maxed out. I suspect we will limits right around 660-675whp. Which is nice since we still have one more upgrade to make which should support well over 800whp by my calculations. Still no misfire. Still no signs of knock retard. Everything is looking and sounding beautiful. AFR via external wideband AFR is still in the low 12s.

Not much to say other than the car is an absolute BEAST. Probably the fastest street car I've ever driven. Should run mid 10s if I can move that shifter fast enough. Traction is AMAZINGLY GOOD. No doubt because we purposely keeping torque reasonably low (~470lbft) and flat (as a table). 3rd gear and up gets full traction without any drama. Sometimes you get some minor tire scrabble at the top of 3rd gear if the road isn't perfectly smooth. But even that is still very manageable. FWIW, the car is running 265mm wide Bridgestone RE11s with m3 bushings/arms and Koni FSD shocks.

And the Procede is doing an incredible job of keeping things safe and stable. We have incorporated a very slick form of lean-run protection. And even more sophisticated methanol control logic. Both will be released later this week as a firmware update for everyone to use. And as always, boost control is rock solid. Peak WGDC is still only 50% at 6500rpm/22.5psi. No unwanted throttle closure. No boost oscillations. No AFR lag/delay. No smoke out the tailpipe. No wastegate rattle. No turbo siren. Just insane how it is able to manage a 630whp engine just as easily as it is able to manage a 500whp engine.

Cheers,
Shiv

PS. We did a couple pump gas (94oct) runs with NO meth. Still some more tuning to do. But pretty promising start:


PSS. Our car was shown at WekFest this past weekend. Look what she won

[Aridk]

This is getting more and more impressive by the day

Edit;

You say still another 100hp in there? will your fuelupgrade be able to suport this? and Your plan for getting there Is that "just" add 1,5 -2 extra psi?

[Fundahl]

Wow...

The N54 is proving to be more and more awesome.... and still room left to go.

[Rysandro]

God damn, ur going to need some 275 Nitto/Toyo semi slicks soon!

[335iJWC]

There is no doubt you continue to exceed expectations!!!!!!!!!!!

Im seriously considering this, is pricing on the horizon!

[AcExSpades]

Holy crap guys! Very nice update.

I was going to get COBB, but I'm thinking Procede now

[SIKH335]

at a boy!!!!!! Thats some solid numbers!!!! The turbo sounds so Sexy !!!

[venom3469]

This is amazing!! Great work Shiv!

[99three]

That is amazing progress Shiv. You mentioned that you are keeping torque low at this point, but I'm curious if you are able to move torque earlier in the RPM band for the folks that like to feel that kick a few hundred RPM's sooner. How are you able to fatten/lean your fuel and can you please elaborate the lean run protection you've implemented? Good job!

[TMR]

Awesome work. absolutely awesome. now you are making me want to sell the M and gets a 335i again.

[M3_WC]

Did you get in any pump only runs like you said you would do? Like to see what your fuel solution is doing without meth.

[werke-t]

Omg shit just got real...

Why did I just buy downpipes.... Lol... Seriously...

Amazing work! Glad I went the Vishnu route

[pentaxis]

So awesome. I am excited to see what kind of boost this block can handle, and what power can be made!

Yes, pump only made 505whp . I'll post those runs up later.

[TMR]

Is this done on the same Proceed Rev 3 many of us already have or a custom one? Cause if its the same one everyone else has, this goes to show how well the proceed tuned cars are being safely ran up to higher levels on these cars.

Nice, Doing a great job with this kit.

Yes, same exact Rev3 Procede that thousands of you guys run

[Jimefam]

Wow shiv congrats on the awesome numbers and putting to rest alot of the DI weakness talk. Hopefully I'll get to see what you can do with 50% more displacement and two more cylinders somewhat soon

[SIKH335]

Im sitting here thinking what the hell am I gonna go with 187whp more and all I can do is Grin!!!!!!

[Mr_PharmD]

man, i was happy with 585 but 6XX is incredible. I cant wait to see the numbers on the AT.

[lpphreakx06]

nice!!

[E92ML]

Wow that is some serious power! Nice work guys
