Right now, it looks like this thing will rise from the dead over the Easter.

No to a dyno this weekend but yes to an exhaust sound check. We’re really interested in how well our theory works on exhaust sound. I did simulate it a bunch with some computational cost, but who knows how accurate those simulations will be. Restriction will be near zero given the sizing, but the actual sound is to be heard!

Might want to consider installing something removable over the intercoolers (bug screen or something similar) to ease the cleaning process. The 996 has the radiators with ducts like this and everything from cigarette butts, to tire chunks and an amazing amount of gravel collect in the radiator fins becaseu the ducts have no space at the bottom for debris to fall out.

Black wire mesh option is available, and we may add that. The flow areas work out fine even with the mesh.

current GT2 has mesh all the way flush with the bumper for that reason too.
even recessed slightly gives a "shelf" for stuff to accumulate on against the mesh.

put a hinge on it so you can get your red bull cans out

Default Big a$$ oil cooler

This is the big oil cooler, probably double the stock GT cooler volume. Plus for thermal stabilization, the oil gets run thru one of the radiator end tanks, too.

Default Update on intercooling and oil coolers

Normally aspirated folks should pay attention to the dual core oil cooler setup!

I don’t know the exact model, and it’s not my IP to give out as I didn’t do any design work on that part. That said, you can probably look at the video, measure the space, and then guess from the Setrab catalog which slimline coolers those are.

John’s close to firing this thing up. He just tested fuel pressure!


To be completely honest, I’ve really been slacking on all car project related stuff recently. While John has been working on the car over the last three weeks, I’ve been doing some traveling. London, Vega$, Turks and Caicos, Vermont. Hard living but not a hard life....
