F10 M5 ESS_JB4 760ft-lb/719whp

[allmotor_2000]

Folks.

Some update on the car. Following mods:

ESS S2 custom flash
ESS Prototype Turbos
BMS JB4 S2 - full CANBus access
BMS Boost Control Module (BCM) for direct WG control
AMS catted DP
RPI Exhaust
SSP 16-plate clutch
MSR Intake / Charge Pipes
Methanold Injection with BMS FSB Integration

Dyno Conditions:

Temp 89F
Humidity 27%
93-Octane + Meth (49/51 - BoostJuice)
Running larger wheels (315/30/20 R888's)

Car continues to make progress. Started off with the ESS prototype turbos (still in development) and their custom flash. Removes speed limit, widens trim values etc. To this we added the S2 JB4 (with Canbus) and the BMS Boost Control Module (still new) for direct WG control - helps fine tune over the base flash maps. Did a few pulls this morning and the car put down a best of 760 ft-lb torque at the wheels and 719whp.

There are some comparisons at N54Tech.com on comparisons to Terry's own car with stock turbos.

Few highlights from this particular setup:

- Car has loads of torque all through the power-band (courtesy of the turbos)
- Can keep 26-28psi throughout the power band
- Clutches DON'T slip (SSP 16-disc version installed by Joe @ TrinityAutosport)
- Boost displayed in the fuel guage (> 50% throttle)
- Steering wheel access/control for maps

Thanks to AJ from ESS and Terry from BMS for all their help and support.

More to come.... not done yet until we hit that 1000 mark (crank)

That's a huge Power out there congrats and please drive safe with all that torque.

Congrats bro! Can't wait for that to happen on my car too!!!!

[allmotor_2000]

You are next.... will continue to push th envelope!

[Andym3100k]

I'm waiting.......

[greentrbo95gst]

Dude you need to head to Famoso ASAP.

[IANNUZZI]

Love the powerband, great you are moving this platform forward....

Why does the torque dive at 5200 rpm on your upgraded turbos vs 5900 on stock turbos?

[Mike@N54Tuning.com]

Awesome numbers!!!

AWESOME!!!

Trying to figure out the power band - it should continue making power until 6.5K. We did some Vanos adjustments so should fix that issue shortly. It should (hopefully) reach 750 at the current boost levels.

Alternatively there is a choke point somewhere and peak power is achieved earlier and it's flat from there on out.

I have older curves with these turbos that continued making power to 7K so just need to extract the same at higher boost and airflow levels. It's a process and takes time to optimize.

Bro, very good progress on that. How do u make adjustment on the Vanos? Thru JB? Or other tune? Your car is really going to be a beast!

VANOS and timing adjustments are all flash. The stock timing map advances timing > 5.5K. Can reach upto 15 degrees at 7K. Mine was tuned to be flat 11-12 degrees from aroudn 5K onwards
so we will be addressing that. Down low at Max Torque (MBT), OEM timing may be too advanced for high boost levels. I am running about 4-5 degrees less timing than OEM in that 3-4K RPM band under

Dude been a long time. Hope you are enjoying your F10.

This is pretty nuts. Flash tune combined with JB4 combined with bigger turbos? There should be a sale on clutches if you want to get this setup. Lol!

As always, glad to hear ESS leading the way.

Both ESS and BMS... JB4 allowed us to uncork more boost!

Really sound good, did u try out yr 100-200 or 60-130 timing? I may hooking up a Dimsport to custom tune my set up......

There was a 6.7s (60-130mph) run but not < 1% slope. Need to redo once I fix the top-end. I will be in Spore Sep 5-6 and Sep 8th

Wow 6.7sec is really very fast! When u r here we go for a spin

[6spdterror]

Insane power levels! Thanks for pushing the envelope and taking the platform to new levels

[allmotor_2000]

Latest for now. Next step is another larger set of turbos...

One of the runs here is from last time as a reference.

Very nice! Glad to see great numbers from this project.

Congragulations pretty much the only guy pushing the platform. Hopefully you carry this thing and set the bar so others feel safe going further.
