I remember Drew mentioned/pointed out when I picked mine up that it has a new flapper and arm, but this was in mid-September, so I'm not sure if it was changed since then? Would my EF3 finished in early-mid September have this taken care of already?

^^is that what you issue was this summer?


Yea, at proving grounds even. That's why I cut like 3x 1.6' 60' times and would only run a 12.3 or so...the car was only running like 24psi up top. Then I added more WGDC in vein and got it up to 29 or so and ran several 11.8's, but the car would just fall on its face off the line as if rpms dropped below 5500 or so the car had zero power.

Also why I had a miserable time at autoX, no boost under 6000 = no fun! :)

Glad to hear your turbo is healed, Scheides.

Since Murlo's car appears to be on the fritz, I'd welcome some T&C on the cruise if you're up for it.

Only the turbine housings are being exchanged, not the entire turbocharger.

Sweet, glad this fix has you rocking again!

I vote leave it running 39psi :)

Tim was yours a new turbo or an upgrade of your OEM?

I'm afraid we wouldn't have had the replacement parts at that time sir, but again it is a small percentage of the turbos we have sold to date that have experienced this.

Ok. It's not in the car yet so I would rather just take care of it. I'll be in touch! Thanks for the heads up.
