Careful my friend, to be making only 39ft-lbs at 9,500rpm on an engine that is not asthmatic, it means those valves are jumping around like my man-boobs when I run. Nobody wants to see that, and nobody wants to see you drop a valve in everyone's favorite turbo d-series.

It is a very good idea to test for the piston to head clearence now, than later, just watch the extended RPM testing with the valvetrain in that state of bounce. But, like i need to tell you that, you are the guy who i take my cars to to get tuned! You're the man James!

I'm very excited to see more pics as it develops!

Haha, yeah we decided to step things up a few notches. Although the ebay turbo did me no wrong, I think a lot of people got the wrong idea about ebay turbos being great or something.

One of the best looking manifolds I've ever seen.

Thanks! That's pretty much what everyone that's come by the shop and seen it has said. Must be a good thing!

that's alot of bling for a sohc. almost not your style haha

Haha, you know me too well! This setup almost feels foreign to me, it's got too many high end parts on it! That's OK though, it's the only car I have, and she deserves to be rewarded for her past service! (right?)

Thanks for the advice Luke, it's always appreciated. I think the high rpm power loss was related to the stock exhaust manifold and stock cat though because -

When I've seen valvetrain float on the dyno before there is a particular sound that accompanies it, and the power literally drops like a rock. Maybe I shouldn't have used that term to describe what it did. It didn't have a sharp dropoff in power, it just continued the downward slope seen after 8K rpm in the chart I posted.

I'll have more progress pics tomorrow!

You're right. Stock manifold and cat would cause some major restrictions at 9500. However, I can't help but think, to drop that much torque, you would need an effective cylinder pressure drop of so much so rapidly, I can't help but think there is some extra valve bounce happening, but I could be way off (very tough to make a guess on something from only a single point on the graph rather than seeing the shape of the curve), and your experienced ears would hear it.

You're the man James! Tell Ricky his work gets more and more impressive everytime I see it! He is going to be one of the very best in the world soon if he keeps improving his fab skills!

It was great to see you last week.

Post up a picture of Kevin's car for all the turbo guys to drool over

I know Matt took one where they were painting the cage, and I was in the background doing a wild-man face through the window

lol

man, that top mount is sexy.

Mr. Kit · 06-21-2009, 10:23 AM

very nice build,

James: can´t wait to see the results of this beast at the track.

JFK78 · 06-23-2009, 12:55 AM

Ok, so after a lot of hard work, it's pretty much finished minus a few small details that will be changed (mostly cosmetic).

Here's a bunch pics from today. I hope you guys like it!

SOHCinWA · 06-23-2009, 01:04 AM

That is one of the Sickest Valvecovers I have seen James..

rushi · 06-23-2009, 03:24 AM

Looks great, and very interesting solution in valve cover breather setup

Big Tuna · 06-23-2009, 03:57 AM

I have to ask, why you did the catch can that way?

If the motor pushes out enough oil to start filling the can in the event of a serious motor issue the can cant vent once the oil level rises to the level of the AN fitting, after that it just turns into a bubbler and pushes the oil out with the air.

Wouldn't it of been better to put the fitting as high as possible in the can so in the event the motor pushes out a ton of oil, the oil can fall out of suspension and fill the can while the gas escapes?

The only reason I am saying something is I have seen a similar style can setup be very ineffective during a motor issue.
