digs are for best traction setup, rolls are for HP

Did it help?

haha I laughed. But seriously, Digs are the real showing of how fast the car is from point A to point B, including non motor upgrades, suspsension/tires/lockdown kits/CF DS/HS's / little things. If you just want to see which motor makes the car move faster, than yes rolls are better. But there is no way to make a 100% fair start. As well its more of a drivers game if you're driving a manual. (my opinion)

roll only, 6mt 335i = you wish it hooked.

Once the tranny slips once its kinda the end of it. I'm waiting for e90company to flash the alpina software. After that we'll let it shift.

second gear around 4k rpms. Or, if I'm running racegas, 3rd gear 60mph 4k rpm

It doesn't really matter...

What's the issue with letting it row through the gears? Why would it cause the tranny to slip at 16.5psi

Almost to the point of having too much passion! :) I can't imagine how hard that must be to let that car go after that much work converting it. I think he did an awesome job - I love everything about it. The person who buys this car - will have something special.

I knew I forgot something lol next vid will have the head slamming. Like Dan said this still a very preliminary map. It's actually the standard bms flash. So nothing special going on to help spool. It's actually not as laggy as it seems I guess everything just happens slower in video. This is also the largest a/r vband housing they offer. The good thing is this turbo has great transient response. Once we start letting it shift it self it's gonna be a rocket. I don't think it'll lose much boost at all between shifts.

LOL

Damn... You beat me too it...

if a 40 roll, what gear/rpm are you at?

HAHAHAHAAA!!

Very nice. I like the intercooler water spray function. That guy definitely has passion for what he does. Re-plating the fasteners is evidence of that.

This^ 30 or 40 roll and stop at 130 or so

I don't think you need to remove the DPs to get to remove the primary O2 sensors. I think what Terry is saying you should do is swap the two primary sensors and see if the problem moves to the other bank. Just remember to swap the end that plugs into the engine harness as well. You will probably have to route the cables over top of the engine to test this because the bank 2 sensor cable will not reach the bank 1 sensor plug on the engine harness. Swapping the primary and secondary sensors would not be advisable under any conditions. By "front" and "rear" I believe Terry@BMS was referring to the bank 1 and bank 2 primary sensors only.

Lol, I don't either but it's more cost effective to do it this way. @Sticky Maybe if I buy then, when I am done BimmerBoost.com could buy then from me and then rent them to people who need them. A kind of BMW special tool rental program. I've seen those kits, but they don't include the pre-tensionors (thrust blocks as they are called) or the valve compressor tool. I guess because it is an inline 6 you can't install the cam shaft in any position that does not cause it to actuate a set of valves, so you need to depress those valves before the installation. Did you just remove the head from the engine, or did you completely tear the head down and rebuild it? When I pulled the aftermarket DPs to put the stockers back on, I did see a bit of liquid oil behind the turbine wheels. This and the oil on the outside of the turbo center housing makes me think it is the turbo and not the valve stem seals. I would think if the oil was leaking down the exhaust valve stems, it would burn before making it to the turbos with the exhaust valves, ports and manifold all being so hot. So liquid oil in the turbos points to the turbos being the source in my mind.

Roll... Why cause I said so dammit! Plus I love top end speed

Sorry I meant N55 midpipe not downpipe

I would say replace the O2 sensor on the bank with problems. Or even better, replace both of them, because the labor costs are high. Also log the low fuel pressure, etc. I remember someone having some misfire problems with the fuel pressure sensor and solved them by replacing it.

Those tools are like Christmas goodies lol...i dont work on these motors enough to warrant buying them :-/
