been busy little beaver this week...got another turbochargers fail sitting at the casa.

 

Well, I've been out of the loop...

 

why yes, yes you are...lol
need to call every once in a while and youd know this stuff!

 

Hey guys,

I am in Philadelphia and looking for somebody who knows what they are doing to install my TRD lsd into my Scion. Was thinking about having a dealership do the install but I don't have any confidence that they know what they are doing. All ready had to many half ___ job experiences with Toyota dealerships. Anyhow, I was wondering if you may know anyone, or a business, near or in the Philadelphia area that would be able to do a flawless lsd install at a reasonable price???
Thank you in advance......

 

not really, but you could talk to Chris if he's up to the task and ship it to him.

 

Alright guys it is official, she lives!

I've been driving it for about a week now and everything mechanical seems to be in place. Had some extra vibrations (motor mounts) the first two days, but somehow it died out. I have spent most of the time tuning the car, it was kind of difficult at first, cuz it was very rich off of boost and the car would buckle when part throttle in it.

At first I though it was the fuel filter clogged because of the E85. Took the fuel pump out for inspection and everything was fine, clean filter and no rust whatsoever around the unit. That goes to show that if ur system is clean to begin with, there will be no problem with E85 messing things up. One thing I did was to make sure the grounding point of the unit was actually making contact with the metal of the fuel tank. Very important to ground the system with E85.

Now, I have different theories as why the other engine gave up on me.

1. While in Austin there was one occasion when I had to pass someone on the highway to keep up with everybody else (club). I didn't know where the place was and everybody was racing. (I was so mad) Anyways, while I was passing up this car I over revved the engine. When we finally got to the place the car was kinda rough at idle, so who knows what kind of damage was done to the engine.

2. Tune: Most of my off boost area was kinda rich from adjusting it from E50 to E85, the boost area did needed some touch up. Ex. 1-6 psi was fine, but I noticed that the 7-12 psi was a bit too lean. At the time of the incident the car was at 12.6 afr and the IDC went from low 80s to 97 IDC. According to the log the car did go through 13-14 afr from 3200-4200 rpms before dropping to the high 12s running to 4600 rpms and giving up.

My brother was keeping an eye on the AFR's, well that didn't workout too well huh?

So there it is, high AFR's makes for a hot engine even if u r running 105 octane alcohol fuels. It did give up at the piston rod and the car was running like doo doo after over revving it, so who knows. It could have been damaged before running lean.

As far as timing goes, it was very aggressive. Taking off about 3 degrees at 12 psi. It was running great with E50, but the lean conditions was just too much.

Questions?

 

nope....no questions from me, well except are you comeing over tuesday?

 

yep!

 

not sure if I will be dyno'ing now though. I was thinking about buying a fuel rail, first I need to find out if the increase in volume inside the fuel rail might help kick down the IDC's a bit. I might call paul and ask. Anything for an extra 10-15% head room, I don't have the cash for a fuel return setup now.

 

forgot to mention, if I give u the cash. Could you order it for me? Wifey and I setup the new budget, but I have a couple of bucks stashed for this. :-)

 

lol...sure bro

 

For those wondering, here's the reason the car was stuck in reverse when in neutral.



Because the bracket was under the bottom gear lip, it was always engaged. Same reason I couldn't move the lever into the reverse position, the gear wasn't able to disengage on it's own.



This way when the bracket moves up and down, the gear goes with it.

I kinda knew from the beginning that I made that mistake, something simple that will make the whole process that much harder, cuz u will have to drop the trany again and open it up. Opening it's a breeze, the problem is having to take it down and installing it back in the car. Thank God I had an engine crate available, I was able to take it out in about 20 mins and install it in about 15 mins.

The LSD has been working fine, no weird noises or hum vibrations it seems just like stock to me. As far as traction goes 1st and 2nd are still kinda useless, but it did cut down the spin time to about half what it was before. 3rd gear is great, no crazy spinning around like before at the beginning and half way through 3rd. Surprisingly it did cut most of the torque steer that I had before, it used to feel like I was riding a crazy hose pulling side to side. NO MORE :-)

Have not done much with it cuz I'm just trying to get the car tuned properly, once I'm done I might do a short takeoff vid. Maybe a burnout too.

Later.

 

Carlos you're a LSD pro now!

 

nice you got the lsd working.. question on your previous post, what were your EGTs during lean condition, I had some lean conditions switching to E85 13s- low 14s afrs but i didnt notice too much rise in EGTs it was like 1200ish F i believe. 12-12.6afr, never had any problems at all, good power, no knocks, good plugs but then i tuned it down to 11.8-12afr.

 

nice work brethren

 

I wish I had an EGT gauge, something for next season I guess. That's good to know that it still ran cool enough 4 u, I guess if something was wrong with the car already like I mentioned (over revved engine) that could of been part of the problem. How many degrees r u pulling at 7-12psi if u don't mind? I just think that running 13-14 AFR's for about 1 - 1.5K through max torque area wasn't helping either. I'm at mid-low 11s for the time being, but will go to 11.6 AFR 5 psi and avobe eventually and leave it there. As far as timing goes I'm pulling about 3 deg at 7.5psi, 4 at 10 psi and 4.75 at 12.5 psi.

Not that I'm boosting all the way up there now, I'm just running 9psi. Most STI owners tuning on E85 get more power at the same psi level, roughly about 25hp and 40tq. With that being said running 12.5psi on E85 like I was, would be kinda playing with fire. I put down 303hp 300tq at 10-10.5psi with 93 octane gas, that leads me to believe that I was deff pushing the limits on the poor stock engine.

 

U already know. So, when r we taking care of urs?

Thanks Chris, see u tomorrow afternoon. Oh yeah, forgot that we had a babies ultrasound scheduled for tomorrow morning. KK goes to work in the afternoon anyways. I could go really early and then come back in the afternoon though. Let me know bra.

 

btw you have an OBD logger right? you happen to know your total timing on E85? around 7-10 psi? mine is 22-26 from lower to higher rpm.. if you are not comfortable with 12.5 afr you may wanna take out a bit more timing until you get your afrs dialed, i doubt EGT is your issue but more on risk for preignition

 

when ever you can get here is fine with me, prolly wont start anything till after 9am, gotta have my coffee first.

 

Don't have one, but I'll keep an eye on that on my next pull. I just got a program called ScanXL, which is supposed to log everything there is. Problem is that I don't know what OBDII to USB connector for the laptop I'm going to need. Any ideas.

I'm not that concerned about running 12.5, just got this weird feeling still around from the incident . Ur probably right, it could be a timing thing more than anything else. Wish I had an EGT gauge pre E85, no biggie though I still have my gas map. I could always run one week on gas just for kicks.



Hey Chris, I copy.
