Re: From ashes
If its going to fail it will fail very soon, assuming you aren't exceeding the limits via tuning, fueling etc.
I agree with Kracka. You'll need 400-500 miles for the clutch, then at that time you can check for leaks etc but then you can turn it up. Worked fine on my motor. But the initial ring sealing etc is like the first 10 minutes on the dyno. I did do a prolonged breakin on my newest motor though with A LOT of vacuum pulls but many shops just put the car on the dyno after being built and let er buck. Preference really. By waiting 500-1000 miles you aren't going to prevent any problems that came from assembly or internal parts. Maybe an oiling issue or fueling but not assembly. |
Re: From ashes
Yeah, I don't buy in to any of that ring seating theory. That's normally done with in the first 10-20 miles on a new car (or in this case, new pistons). A couple of pulls on the dyno will take care of that.
I'm still debating about E85. Maybe I'll run it on pump gas for the next month or two (1000 miles or so) and see if I still want to go E85 at that point. |

Stay pump to start and switch when you get bored. Take this in strides, don't do it all at once unless you are dead set on it. Easier to troubleshoot and get working right the less stuff you change at a time. |

It can be done if you take your time and do it right and know what you are doing. But its much easier to do it piece by piece, agreed. |
Re: From ashes
ID1000's and a WB400. I don't have an analyzer yet though (if I do, I'll probably just baby bottle it). That ought to be able to support e85. More so my concern/questions are about varying levels of ethanol and how that affects tuning/reliability. Also, because I have a winter beater, I'm concerned about what happens when the gas sits for too long and absorbs moisture. Yes, I realize it's dry in the winter, but it's still a concern if there's a long stretch of time where I can't drive the thing.

Re: From ashes
Side note: some of you know I also have a project going on at my desk at work, lol.
I get bored some times... http://img10.imageshack.us/img10/913...9951047495.jpg http://imageshack.us/a/img843/7600/4...1368074259.jpg http://imageshack.us/a/img145/8288/3...2857640985.jpg http://imageshack.us/a/img195/4065/5...1828646269.jpg |

Re: From ashes
I've got two sets of evo pistons and rods too if you want some other cool stuff ;)

Re: From ashes
Up and running again!!! Got some more testing for leaks tomorrow, then dyno time!

Re: From ashes
Just got it back from Ron's today.
http://imageshack.us/a/img829/5530/imag0269d.th.jpg At the moments it's making 320WHP/280TQ at 20PSI on the break in tune. Once I've got a couple hundred miles on it it'll go back to Ron's to finish the tune and get converted to E85. Should be pushing 400+ with that. |
Re: From ashes
^Congrats!!

Re: From ashes
Good news, bet it feels good to have it back.

Re: From ashes
Based on what Tim made, I assumed I would be right in the 425-430 range. I was right on, at 425whp/366tq@30psi
http://imageshack.us/a/img834/5259/dynoi.jpg The turbo wanted to keep going, but we ran out of pump with out the BAP, like Tim has. |
Re: From ashes
That's so sick that these motors make max power at redline.
|
Re: From ashes
Rev it to 12k! J/k good work!
|
Re: From ashes
Nice job! Awesome numbers!
|
Re: From ashes
Nice! BAP or W400 and give yourself some nice safe headroom :)
|
Re: From ashes
Yeah that curve wants to keep going, rev that bish to 9k!
|
Re: From ashes
That EF3 is supposed to be good for 650. BAP would be the next step. But not sure that I'll end up getting around to that for a while. I'm quite happy with where its at.
|
Re: From ashes
550 bobby not 650
|
Re: From ashes
Do the return line siphon drill mod before you put a BAP on there (see my post on evomn). Your W400 should already be flowing as much as my dw65c with BAP does I would think.
But great numbers anyway! |
Re: From ashes
Oh, I missed that you went with a W400 already. I am shocked that it is out of fuel. Is it the e85 version? Do you have a fuel pressure gauge at all? Its possible your base fuel pressure is off the map and severely limiting the flow of the pump.

Re: From ashes
Study up on how fuel pumps work. The higher the pressure they are pumping against, the less overall they will flow. Restrictions in the fuel system can lead to this.
Go back in my project thread about a year and you'll see all of my W400 shenanigans including fuel rail and siphon drilling. I actually bent my stock FPR to reduce base fuel pressure while installing a boomba fuel rail. Lots of fuel capacity on my setup now Drilling the siphon is pretty easy, it takes about 20 minutes to get the fuel pump out, drill it, and get it back in....but having a gauge is pretty key so you know what's actually happening instead of guessing :) |

Re: From ashes
Keep in mind, with super high pressure, you can pretty easily pop the return line off the nipple at the tank. Happened to me twice before I did the drill mod. Hasn't happened since. I was reluctant to just put a tighter clamp on, because I'd rather have it pop off there than in the engine bay.
I would do what Scheides said.. put a fuel pressure gauge on there (or have Ron do it) and if it's crazy high, do the drill mod and see if it helps much. It will definitely help, but it might not be enough with the w400's flow at idle. |
Re: From ashes
fpr and drill that shit out bobby, better safe than sorry. Welcome to the world of modding haha

Re: From ashes
Thanks Tim, ill keep that in mind!

Re: From ashes
Well, here's a bummer update.
About 2 months ago now I took the car down to Ron's to have said ignition problem looked at, and it turns out that noise that we all thought was piston slap, was something more severe. So MAP has had the car down to short block for a while now. Cylinder #3 was fuel washed. The injectors have been sent to ID for inspection. They called me this morning and said that nothing is unusual that would indicate the injectors were the problem. One was flowing a little low, but still within Bosche's standards. FML |
Re: From ashes
That sucks to hear :( What are you going to do with it now?
|
Re: From ashes
Ouch. Who built the motor?
|
Re: From ashes
So whats wrong with the motor?
|
Re: From ashes
So what was discovered regarding the noise, spun bearing?
|
Re: From ashes
Yikes...
|
Re: From ashes
Hmmm, this sucks :(
|
Re: From ashes
yes it does suck. I too want to know what a washed cylinder would do
|
Re: From ashes
A washed cylinder would be a cylinder with no/little compression. A washed cylinder is shiny and has no cross hatchings.
