And the wanker, well what else can one expect eh
?!
We're going to be hosting this locally on our site too so hopefully you can see that too. Have you tried different PC's?Hehe thanks! Wanker's actually Dan's adopted middle name!
Great write-up, thanks!
Two questions though, Porsche stated 3.8l would be the limit of reliable displacement for the GT1-block, how should that be interpreted?
I see you're running on 91 octane and 93 octane, are octane levels always this low in the US? In Europe you can at least get 98 octane and 100 octane is often available too... Or does it have something to do with different octane reading (RON vs. AKI), in that case "your" 93 would equal "our" 97-98 RON?
Just curious

Here's James starting her up for the first time with the 3.9. I think this was right around 11 PM that night. Sorry for the phone-quality video.

Here's a few pix/updates guys on the two 997 GT3's we're building... one is a white 2008 and the other a silver 2007.
Out she comes:
Guys we should all take a lesson here... This clutch has seen 37,000 "hard" (and I mean that) miles yet look at the condition
Rear main seal? Not so good... hence we're replacing all of the cars we do these motors on (or indeed LWF's) with the 996GT3 one instead.
Over to the white one... out she comes too:
A pair of very expensive motors...
The higher mileage motor did have a lot of "dirt" and other fun stuff to clean off (along with the harnesses and other parts):
Out come the cams...
Not bad for 37K? Actually pretty darn clean/amazing...
Those Ti rods are soooo light:
Fast fwd many steps
And in go the EVOMS head studs...
Ze liners...
The white one is also getting the TechArt noselift kit installed (just like on kermit):
for the rear...
Ze front...
