'06 MS6 Stock Block testing (6266 + PI LOL)

Love seeing speeds race man great content on this post and 10 thumbs up for me!

 

How many miles with this 6266 and PI setup just out of amazement? Lol

 

First start with this setup was with 65,041 miles on 6/14/20. Car has 74,2xx now.

So just a hair under 10k miles so far.

Base map was on for 1 day at 21psi. Been running 27-31 psi since then aside from the ~500 miles I ran 93 only for that road trip this past weekend.

Im gonna try to get the car on the dyno next month. Then will probably do a compression test for the lolz after.
The 6266 itself probably has closer to 15k miles on it tho. Between my ms3, the gray ms6 and kow this car

 

If Anyone is curious. After going back on an e60 mix yesterday

Did that race on the mix, and then 283.9 mostly highway miles

Heres the mpg for E60 mix (math says e57 for this fill up as I wanted to fill it completely and put a lil extra 93 in there)

 

Is that built ms6 around 475ish?

 

low 400 likely. 25psi on first e-mix revision. Probably has a few more pounds of boost and a 3-4 more degrees of timing to go up top before tune is done

 

Ooh. I logged that run as well. Heres 3rd and 4th gear split into two excel files and run thru VD

For a journal bearing turbo and me keeping tq in check down low, this sucker lights up quick considering it sees max vacuum between shifts and has to spool back up since I cannot flat foot shift without the wot box hooked up (when using larger amounts of aux fuel, you get high rpm shift lock out when you try to FFS). Not that id run a wot box on a stock engine or clutch anyways lol

Shared this in the Face space. Will share it here too if anyone is curious as to the response/spool on a giant journal bearing PTE turbo.

Since we're talkin turbos.

This is a stock block ms6. With a gen 1 Journal Bearing PTE 6266 (Vband) 0.82A/R

Self tuned

I'm neutering spool severely to manage tq and save the rods.

20psi at 4k, tapering to 30.xx-31psi up top as seen in the first pic

2nd pic demonstrates respool time when lifting during a shift. Going from 31psi to full vacuum back to 31psi

Not bad for a turbo that costs sub $1000 brand new, and thats being limited by a stock block, And without a wot box hooked up to keep in boost during a shift (cannot FFS with cobb only at this power)

This particular example is on an E60 mix with port injection

PTE FTW

 

Just curious, but why would your calculated load be less than mine when making more power? Just because of the faster spool time I guess right?

 

Nope. Maf scaling for port injection. I dont use a normal maf curve. Its flat lined at a point which you can see in the log. Running a normal maf curve or one scaled differently, my calc load would look much different

AKA mass airflow being capped at 283.xx from 3.8volts on up.

Not all tuners use this method. See andales thread on tuning aux. He kind of explains the traditional method versus what I do.

Its just a personal preference. Flatlining the curve does make for more effort in changing the timing tables by load to make sure it hits what you want it to in terms of ignition timing as rpm rises and load drops

 

What do you gain by doing it this way if it is more difficult to set other parameters around this?

 

How I was taught by my previous tuner to do it before I started tuning it myself. I'm just comfortable with that method and my motto always is; "if it aint broke, dont fix it"

 

The title and purpose of this thread begs to differ, sir.

 

But its not broke.. yet

 

His And hers, turbo 4's

 

One on the right kinda looks slow. Lol

 

So slow

 

Wow that car is beautiful [emoji3062][emoji24]

Havent been on mso in a while. Electrical issue of some sort with the ms6. Hpfp active pressure will randomly read 0 or double digit pressures for a tenth of second in a log and the car will miss due to that. Camera mounted in the engine bay aimed at the FPR shows no pressure loss. And everything else related (hpfp, spill valve, hprv, itfp) all swapped with no change.

Next is injector harness and fuel pressure sensor on the DI rail. Otherwise. Car is pretty much put away for winter.


On a positive note. CarLed v3 tails came in. Put those on the car on sunday.
