Keith, I love your work.

/begin hate
But, I've got a whole gallon of Hate-orade for the Pink and Blue.

So bitter tasting!
/end hate

How many guys you got working on the car?

[Brando]

Whenever my girl peers over at my screen and sees the pink she makes it a point to say how cute it is. We usually end up in a fight over it

Your build is pretty tight, look forward to seeing it next month.

How many guys you got working on the car?

I am the only person working on this car.

CEL: Typically caused on EJ20 motors with a single cam sensor and using a light pulley and light FW or just a stupid light FW. My theory for this is that with only a single cam sensor the ECU is estimating the timing on the other bank. If it rev's too fast it gets outside of the tolerance zone for cam position interpolation. The AVCS motors have dual cam sensors, one for each side. I ran the 1lb pulley and a 14lb (?) flywheel. Never had issues.

Harmonic balancing: I don't know where it is but I saw a technical letter written in response to an inquiry from Subaru stating that the OEM pulley is NOT a harmonic balancer.

Difference: It does. Revs freer, easier to rev match, frees up a little power (more noticeable when off boost). Not my video:

In my experience, it seems that the false misfire code from having a lightweight fly wheel actually happens when pulling off throttle, or when the AC kicks on. Not when you're revving the engine up while on-throttle. Similar theory to yours but the reduced flywheel inertia allows the engine to slow down more between ignition pulses so the ECU thinks it's misfiring.

An actual misfire would behave the same way where RPM's would drop mid-cycle due to a loss of an ignition pulse. With a light weight flywheel, accessory loads can overcome the rotational inertia and replicate the behavior of an actual misfire by having the engine slow down more than expected over a single revolution of the engine. The ECU then assumes there was a loss of an ignition pulse and throws the code for the cylinder that was up for it's bang when the RPM drop occurred according to the crank position sensor.

Edit: The reason this happens more on the 2.0L engines is due more to the lower sample rate of the ECU as the 2.5L WRX and STI in the US all have 32bit ecu's while all USDM 2.0L models ran on 16bit setups. The false misfire codes still happen on STI's, my bud has an 07 STI with both a lightweight flywheel and lightweight standard size crank pulley and he gets codes when in 5th gear pulling slightly up hill when the AC kicks on as well.

Wheres the GoPro video of you driving it?!

[wleehendrick]

Nice shot... looks great! (still trying to dig the pink, though ). Will the intake fit there with the body on, or is that just for g-carting?

[Mechie3]

What's the tab that sticks up just underneath the Sparco lettering?

Not the final intake mounting location, that was done in about 2 minutes.

Mount for the "trunk" Tried to not have the requisite 47 hood pins.

[Scargo]

I like the CAI location. Finally, somebody using the side vents for something. Can't dig on the pink. Carry on.

Ain't nobody got time for dat!
hah that was classic

This is Keith's office assistant. He's in the hospital, he had a heart attack. Turns out the shock of you FINALLY saying something that wasn't negative just pushed him over the edge even with the slam at the end. Don't worry scrote, you'll smile one day and learn not to hate.

[RM1SepEx]

I'll be praying for a speedy recovery, God bless...

[Brando]

That's intense. I wish him a speedy recovery. Get better soon Keith!!

[wleehendrick]

I think/hope that was a joke on Keith's part.

[bstuke]

Have they even allowed it in XP yet? From what I know 2015 will be E-mod.

Yep.

[Brando]

If your joking it might be nice to clarify that

[iWire]

I'm guessing he's fine.

Now we're having fun again! =)

Pretty sure that was a joke...good one too. C'mon Glyn, you've got to admit that was damn funny.

[Scargo]

I didn't know I could bring on a heart attack. I like to think that I had a little help.
Too bad Keith missed my other positive comment, "I like the plumbing work." and an off-hand compliment when I said "I don't think you are delusional." I do like the blue color, BTW!
Might just be SEMA looming. Poor guy.
I promise to lay off. Get better soon.

[Mechie3]

I lol'd.

That killer B oil pan sure is dangling below the frame, you worried about speed bumps at all?

Thanks for the pictures. There are several angles from underneath, like the motor mount pic, that aren't normally posted.

What tubes are you using for the lateral links? They look very slick.

If there's a speed bump on a race track I've got much larger concerns.

Welcome. They're the standard cheap FleeBay chinese 6 piece kit with some fancy powder coat is all.

[SixStar]

Also, yeah I'm ok. It was a bad joke.

Here's the requested video of some neighborhood lapping.

Ha forgot this was the R. Maybe it's an optical illusion but just looked like that pan was going to be 1" off the ground.

[Rasmus]

The location of the brake bias valve gives me ideas.

Guess who is gullable.

Sorry!!!!

[SixStar]

I can turn down the rear circuit only this way. The front locks way before the rear does, but when that changes I can dial it back a bit. WORST case I have to redo one line and I can put another in the front.

Same location as in my challenge car, will be putting the one that came with the kit in the rear (since its just a splice in the line running down console and if needed will install one on front. There is not a lot of console space as I have the emergency brake there, shifter, bias valve and fire extinguisher pull, no room for cup holder in the R

5th pic from top. I see what seems to be fuel lines coming from over the tank and making a 300-deg back into the engine bay. There is enough space to route them there after the panels are on?

Acres. The body is 6-8" away from the frame right here, hell you could route the intake back into the area above the fuel tank if you wanted.

This is semi-temporary. I don't like that if I was to get blasted in the side right there it could cut a fuel line. Worst case scenario I know but I'm going to move them after SEMA. Right now everything is being done fast, simple, and shiny. There will be a 2.0.

[longislandwrx]

Car is looking nice. Wish I could make it to SEMA, seems like 2014 is the year of the 818.
