Very cool,like a lot.

O2 sensors replaced today, not as bad as I thought it would be. I don't enjoy being under a car held up with jack stands. Also swapped out my timing chain tensioner, the one on the passenger's side (starboard) of the engine. No more ball bearings in a coffee can sound on startup.

Conclusion, 50 miles later and there's no codes showing so next step is the last dyno run @ Drift-Office before letting DUDMD have some fun tweaking the engine on his dyno.

Oh and that little secret surprise is coming together nicely. I can't wait to reveal it.

[Plattus1000]

Just passed my emmissions check with the secondary air pump and the evaporative control pump coded out.

In another month I should be ready to delete the cats and have DUDMD code them out too. Then the fun begins.

Oh, and yes, I still need one more dyno @ Drift-Office...

I procrastinate just a tad now and then.

Let me guess .... NOS!

No my friend... No.

Alright. I'm going to guess it's VF s/c kit.

I wish but I think I'll hold out for one of toolman2's twin screw kits. I think he's really got something good there.

No. For the time being I'll stay naturally aspirated. It's killing me not to say anything more but I promised someone that I wouldn't say anything until the install.

[Plattus1000]

I'm not done with this thread. I had all the work done during my slow part of the year and now I'm busy every day. I need another dyno to find out how TerraPhantm and DUDMD's flash performs with this engine.

So far, no codes and it runs great. I do have a tiny oil leak that I'll need to track down but it's below the v/c's and I need to remove the splash guard to really get a look. That means a lift/time. For now, I'm topping off in the morning and not pushing her too hard.

The thread ain't dead!

[Plattus1000]

I can't wait any longer. I may have pipe dreams of adding a supercharger built by Wagons Ho but before all that and as soon as I get this post-tune dyno run in...

This is happening :

Purdy. I need something like that for my 7. The ole 2.5" setup is far too small.
What brand header is that?

Those are Jedders if I'm not mistaken. Read about them on m5board. Not cheap by any means

Yea, read the article. Frankly I'll have a hard time ponying up the coin needed for supersprints, let alone those bad boys.
I'm actually considering the cheapo obx fleabay ones.

Schmeidmann has some now too, I think.

These are the "unicorn" headers by Jed. And no, theyre not cheap but you can see why. They're the type of thing that made someone come up with the idea of putting mirrors under a car at a car show.

They'll fit m62/s62/m60 v8's.

I'm pretty sure you'll need rear o2 sensor extensions, in case they aren't included.

There's still going to be O2 sensors, AFR monitoring bungs too for a future addition of the wind machine.

Long time coming. It's been a work-heavy few months. My car is trashed inside. I haven't vacuumed the car since before the swap. I'm a bad owner.

Sorry, it's the precat o2 sensors that move further downstream and need extensions since there are no pre-cats on the headers like the TU headers.

Them Jedders sure look purdy but $$$. Also, they look big like almost 3" to 3.5" tubing.

[Plattus1000]

auaq, size never bothered you before *wink*

JK


I'm sure they'll be fine. Besides, I'll need some extra room when the blower starts to push. 3", same as I have now.

Yea, you'll need 3+ when "blown" ?

[Plattus1000]

Need...? Want. Back pressure is not a friend of the m62 so if I had the $, I might go cut outs but honestly, just so I could scare people in tunnels, not for performance.

I might need to finally use a muffler of some kind. Hadn't thought about that, might not too. Cart before the horse.
