Default Just another 700whp N54 - 09-26-2014, 12:28 PM

Hey guys,

Was able to get Ando's car back on the dyno to test out the new 1.00 AR exhaust housing. Mods are a JB4, VM top mount turbo kit, E40, meth, and all the bolt ons.

The result was an impressive ~30whp gain from his .84 AR housing with improved spool. Looks like the COMP 6465 1.00 twin scroll is good for a nice spooling 700whp. Even on automatics.

I also plotted it out against Payam's manual trans 335i running basically the same turbo kit, tuning, and mods, and you can see what an improvement the longer MT gearing makes on spool and power under the curve -- on the dyno. In the real world though advantage automatic. We'll find out for sure when the two of them race at Shift Sector in a month.

No RB's were fun too. Can't take anything away from it,
but this is almost 200whp more and pretty fun and cool to drive.

looks like a beast!
i wonder how DD this setup can be?
maybe in low boost setting like 15 or 20 psi for spirited driving?
you dont want to get full 700 hp kick while on the corner edge

What size tires are you running and why do they look so skinny on the rear?

245/45/17 Nitto 555R. I run them on the 135i as well. The 275 version is too wide for the K1 rim IMHO.

With the VM RS1 wheel we have in stock. 17x8.5 front 17x10 rear, I use 275/40/17 with the same power level.

Got some info regarding back pressure on bimmerboost forum. Looks like it reaches 2:1 BP near 27Psi+ toward redline. So were deciding weather to up the AR again, or we should test out a bigger wheel in the exhaust turbine.

Either 1.15 AR with the 6465
Or 1.00 AR with 6467. We'll see how it goes.

We have had a few customers request pictures etc. It seems like the steering column is in the way of the ******** and possibly wastegate. It will need customizing for that end.

Some back pressure data on the 6465 1.00 AR from Ando's car. At WG spring, 23psi, and 28psi. Exhaust pressure is pinned to "low fuel pressure" in the logs.

Not liking the 2:1 back pressure ratio up top at higher boost levels. Hopefully the bigger turbine wheel will help that.

Is this cutout open or closed?

Cutout closed. Opening it may help a bit. It's under 2:1 still but getting there. Turbo is probably maxed out for the current setup. Still 700rw isn't a bad place to be.

Default JB4 for boost control and Cobb backend flash - 11-30-2014, 10:22 AM

Hello guys,

I was hoping to get some help regarding tuning a single turbo kit on my N54 with a Cobb backend flash while using JB4 for boost control. The protuner recommended that I use JB4 for boost control and they would tune my set up with a Cobb backend flash.

Do I need to upload a single turbo map for the Cobb and flash my car and then just install the JB4 for now and then do some data logging and have a custom map made? Since I have the Cobb Ap and was protuned on stock turbos, I was getting custom maps made.

Thanks

It's toast, lol. For any single turbo running an auto you'll need to keep boost at 23psi or less for it to have a chance at living. Maybe under 20psi in some cases.

I have the xdrive and you think I still need to keep it under 23 psi?
