Hi Jack,
You've been very quiet lately. Is all well?
Best Regards
Sune
Bump - Anyone know where Jack is?
Yep. Sorry for being out of the loop for awhile. After two decades of working on other people's stuff, the first movie with my own name on it is getting shot. Right now, we're on day 19 of 21 -- and some of those days have been as long as 17 hours.
Here are a few cell phone pictures of what's been going on.
On the one hand, I'm sitting by a swimming pool on a nice day here. On the other hand, it's a 14-hour day.
Making rain during a drought.
Shutting down a street in downtown LA for a murder/suicide. They made it rain for this one, too.
Strange to be the reason for so many trucks rolling all over the city every day. The crew numbers about 50 and these are just some of the production vehicles.
Ever wonder what a 'Dolly Grip' is? He's the guy pushing the camera dolly on the tracks while the Assistant Director supervises and the Camera Operator (who is also the Director of Photography) gets a ride. (For the record: Gaffers are electricians, and the Best Boy is the assistant to the main electrician/lighing guy.)
This is a set for a writer's office -- with the writer who made it up sitting at the desk.
And all of it is to put together 90 minutes or so of this sort of thing:
Back to the garage.
Jack, why didn't you take the free Listas you were being offered?? That was sacrilegious not to accept them.
Did someone offer me free Listas?! If I wrote something that implied that... well, I'd like it to come true.
Would it be possible to squeeze a rear diffuser under the engine without compromising temperatures? That may be something to look into, especially if you can get it to work with the front aero and the active rear wing.
I tried one, once. I'm not an aero expert, but I don't think I'm running nearly stiff enough springs to actually benefit from a diffuser in the corners (where it would do some good). The one I tested worked in a straight line (where it's not helping anything), but the thing needs to be held in a pretty specific position relative to the driving surface, and that's hard to do. I think diffusers are mostly decorative on production cars.
Now, in theory, you might say that engine fan is blowing in the wrong direction for down force.... but the sheet metal around the engine, everything was designed for a certain direction.... and experimenting would be much too expensive. (As in, if you screw it up and the engine overheats...)
Also, "underneath" air could be dirtier. And who knows, maybe it helps with the airflow over the back of the car.
I've heard guys talk about this before, but I think the dust and road debris getting sucked into the cooling fins around the heads and cylinders would be problematic.
Hi Jack
I recently have been doing a lot of reading about installing a Chevy LS v8 engine into various Porsches. I realize this may go against a Porsche Purist train of thought but I was wondering what your thoughts/opinions are on this subject.
Thanks

I think it's a great idea -- except for the problems of cooling it. It's the same with a later-model water-cooled Porsche motor. My car just wasn't designed for ducting air to radiators.
Jack:
A week or two ago I learned about this thread: a man in Scotland putting a newer (but not super modern) Mercedes turbodiesel into an older (R107) SL convertible.
I post the pic here because he put a two post lift in his small shop and it doesn't look too horrible for space intrusion. It reminded me of you and your table lift. Of course, when your lift isn't being used, it has
zero space intrusion.
And I post the link, because... hey everybody! Look at this guy's beautiful, thorough work on this install!

I like his thinking!
I read through this thread a while ago but the other night I caught your Petrolicious video and it reminded me to post in your thread. Great work and I love that 911.
Thank you!
Nice work on the wing Jack, good to see you're talking to Keith Tanner too (he's got some incredible cars and has done some really revolutionary stuff for cheap-aero

)
The jury's still out on whether it's going to do me any good, but I'm doing more testing in early December. Keith's been very helpful -- nice guy!
Hi Jack. I've just completed all 198+ pages of this thread. Phew - that's taken some time, but you (and many others on GJ) have motivated me to look at my poor old garage (and as far as the boss is concerned - rubbish repository) in a whole new light.
I've already used advice from here to make a new work bench from scratch (& a ripper it is too), and look for ways to get everything a place, off the floor as well.
Anyway, notice you haven't posted since 8th August so hope all is OK, and I hope the DRS (from F1) wing worked OK.
From the Land Down Under.
Thanks for making it all the way through! It's a slog, but also a pretty great discussion at times.
Jack, love the garage. It goes without saying of course, but I don't think I've ever posted in this thread. Just read through it.
Thanks.
Thank you!
