Last night I got a 6766 and DW300 from NF and put them on my car. Comparison Photos 62mm 67mm 62mm 67mm
We haven't done much tuning with the 6766, but initial results seem positive. The first round of tuning we had it up to 40psi and it really moves in 4th but boost in 2nd and 3rd was not well controlled. I was running the TurboSmart 40mm gate with 14psi springs. I decided to upgrade to the new(ish) TurboSmart "High Pressure" setup. This includes a new top cap and a 35psi spring setup (25psi and 10psi). Comp Gate 40 HP Gate (35psi) The higher springs pressure setup was a real bear to try and get back together, but I managed to do it ...by hand (my vice wasn't big enough). Boost response on spring pressure looks great. Solid 35psi curves out to 8k.
In 1st, probably not. Maybe if I brake boosted, but even then maybe not. EDIT: I looked at a log of 1-2-3-4 and the rolling into 1st gets me to about 33psi.
Awesome! Hope your motor stays together enough to get some results but 40psi must be brutal on a 6766! Don't some people use a 4 port boost control solenoid on a dual port wastegate like your old one so you don't need such a heavy spring and have some better control?
The new wastegate cap has a spot for a port as well. I just don't have it screwed in. 4 port could work but with the stock ECU (especially my 16 bit) it probably wouldn't have the resolution to make a proper boost curve.
This weekend I installed the Bluetooth E85 sensor from FlexConverter.com http://flexconverter.com/collections/subaru This is a product made and sold by the creator of the Carberry ROM. His ROM's now support full Flex Fuel. I am still using COBB SD so I'm not using the Flex Fuel application, but I still like having the sensor for ethanol percentage and fuel temp. The kit I got is fully plug and play and is set up for a speed density setup. The harness has one connector for the OEM MAF wiring, another wire for a GM IAT sensor, and the last connector is for the GM ethanol sensor. Just splice the sensor into the fuel return line and everything else is plug and play. Install takes just a few minutes. The last fill up I did was from a different gas station (Kwik Trip) that I normally use. It is right next to my work, but normally doesn't have as good of E85. The sensor confirmed that it was only 69%. I'm hoping to get a new tank in soon from my normal station (Holiday) and see how it compares.
Thanks for sharing your experience so far. I keep thinking I should get one of these but I have a sneaking suspicion that since I only get my E from the same station every time (also Holiday) that I don't have to worry about inconsistent E content nearly as much as if I just filled up any old place.
I usually only fill up at the Holiday off 694 and 252 but the Kwik Trip is right by my work so very occasionally I will go there. I've never tested my ethanol percentage in the past or changed maps based on season, so I don't expect much to change, but it's nice to know.
That sensor/app is awesome! So you just don't have it plugged into the ecu harness? I see it says its specifically for subaru on the site but any reason it wouldn't work on a bmw if I just wanted to see the ethanol % and temp like you are doing?
I have it plugged into the OEM MAF connector which goes to the ECU. For my setup I need the IAT portion of the signal to go to the ECU for the car to run. The ethanol % also gets fed into the ECU, but I don't use it for anything. You presumably could use this same kit on your BMW, but you'd have to modify it. The module needs power. On my car it gets it from the MAF. If he doesn't have a harness made for your car you'd have to find a switched power source and splice into that. Just like you would for any other gauge. It's pretty much the cheapest ethanol sensor converter (and has built in BT) so it might still be the best option even if it's not plug and play.
Cool, that is what I was thinking. It is pretty cheap and I would just want to be able to see realtime ethanol % via bluetooth because I'm working with stupid E30-E50 blends and it is hard to calculate when you don't really know what the "E85" portion really is. This would simplify things for sure.
Yeah, I remember the DI Mazda's doing all sorts of goofy mixes back when my brother had an MS3. This would be really nice for that. If you contact him he might send you one with bare leads. I believe he makes them all to order so I think that would be easy for him.
Awesome! Thanks for the tip. Yeah DI fueling limitations can be a pain. I wonder what they will come up with for the new fa20.
Here are a few more updates: Decided to pull the motor out to put into my brother's Bugeye. Ordered parts for a new shortblock. Also purchased a set of Kelford 282 cams that I found someone selling on the forums. Cams arrived yesterday. Still waiting on the other parts. Cleaned up the garage a bit and hung my third tire rack for the slicks.
So what at the plans for strengthening the new block? Sleeving, closed deck, stronger head studs?... Shooting to get it done by PG2? And thanks for documenting all of your work, it can be very time consuming but is helpful and interesting to read for the rest of us!
Internals came in yesterday as well as the shipping container for sending in my case halves. I packed up a set and I will be shipping it today. I have the current motor ready to come out. Just need to borrow a hoist.
Yeah, the transmission stayed in place. Just removed the pitch stop so it could move around a little bit.
Upgraded my newer "CARB" compliant gas cans to the higher flowing "old" style. Advantages: No longer need to use a funnel to fill up my car No longer have to hold down button the entire time it's filling Empties in ~1/2 the time
He "liked" it but didn't make any comment about starting a fire? I'm disappointed. LOL. I only use these for transport to the track. I don't ever store anything in them, so I'm not too worried.
I have a bunch of these for the boat: They are probably not super legal or safe either (they say for offroad/racing use only on them) but they empty super quick and are awesome.
Yeah, those work pretty much just like what I converted mine to. Basically just like how all gas cans were prior to 2009. They have a screw on top on the hose, and then a screw on vent cap. NF has those and I end up having to dump my gas into that and then into my car if I forget to bring my funnel to the track. LOL.
LOL, I was about to post that exact same picture, and say, why not one of these! But you basically created the same thing...just seems like extra work. But I guess if you already have the can, why not.
Yeah, those are about $30 each. My cans were $10 each (and I already had them) and the new spouts were $10 each as well. If I were doing it from scratch I would just get the VP ones. The only other thing I don't like with those is that they're too tall for the trunk of my WRX.
My block arrived! Here are some photos of it. IAG closed deck and 1/2" headstuds. *Studs and plugs are loosely installed by hand for photos.
my mind gets blown every time i open this thread.... even if theres no updates...... ps the grimmspeed dp is fantastic!
I would guess that it's a bit different now. Probably not the same block anymore Failz. Looks like an 8-9 second motor! Hahaha
After sitting in my garage like this for a few weeks things have started to progress... Motor assembly was completed by NF yesterday. I spent the day/night installing it and then spent this morning troubleshooting some issues (boost leaks at BOV, FMIC piping, TGV, and injector, and a leaking fuel line inside the tank) and then got it onto the dyno at MAP this afternoon (tuned by Nuke). I also picked up a DSS CF driveshaft and installed that after the tuning.
