We'll have to go driving neighbor. Nice 928 you have.
If you need anything PM me, & thanks.

I love this.

Thanks Buddy, me too.
Here is another 1.5 hours of shaping F. G. mold.
The base angle is better (more vertical as RS Ducktail) another hour or so and ready to create mold with base attachment points. Base of ducktail will be mechanically fastened with screws and 3M 2 part epoxied which i have found to be as strong as weld in bare metal to metal situation.

The base will then be smoothed out or radius-ed to the hatch as the 911RS lid with USG All-Metal body filler and finish filler, etch and build prime etc..

More lightening to do to hatch (drilling), buying lexan today will router lexan using rear glass using it as my router template. I may install aircraft vents to lexan.

If anyone has installed lexan in hatch opening with good results, please advise, I don't want to crack it at attachment points and lose time/$.
Don't want exposed rivets or machine screws at edges of lexan & will be re-installing black aluminum hatch glass trim. Must look like an RS not track car.
I Will remove the single wiper and bring it back to stock wipers also, Porsche would not have done this with an RS for public consumption/public roads.

Hatch and hood pins with be black anodized aluminum.

Going to Shore for another week, see you when i have something substantial done.

Wing mold is done. Fiber glass work is done,

bringing ducktail to Shore and will finish in early am hours..

Weather stunk, came home for a few days of work and RS work.

Black anodized alum Hatch and Hood pins came, very nice, lightweight and priced right.
Setting those at hatch & stripping paint and mounting ducktail with 3M epoxy hopefully tonight.
Loads of fun.

Ordered epoxy primer and Gulf Blue paint, very excited about the color. Have some pics soon i hope.

Did some research into Porsche and use of Lexan or acrylic instead of glass.
Porsche started using formed acrylic rear windows in their 993 GT3s and the first water cooled 996 GT3 RS rear windows back in 2004 and still do to date.

This thread will continue to get alot of attention, esp when you have such a fine helper modeling the ducktail! Not only that, but great inspiration all around. Keep it up!

Great thread and looks like a lot of fun. I saw you planned on moving exhaust to the front of the rear wheels. Is that "legal" in PA? It wasn't legal in FL a few years back. The reasoning was CO from exhaust being able to enter the passenger compartment with rear windows open on many cars. I don't think it would be an issue on a 928, but if you have State inspections you might want to check. I guess a good muffler shop would be able to tell you too.

Ended up using Loctite Heavy Duty 5 minute Set, Marine Epoxy to set Ducktail. Best suited for fiberglass to steel, it's really on there, i recommend the stuff.
Ducktail looks very good and symmetrical, needs final shaping still with finish filler.
Finished drilling as much as I think can be done when you consider rain water and hatch seal location and hatch strength, old 911 RSRs hood hinges and drilled like this but so much more even. Water will enter hatch frame but drain out in the normal area. I will add a small piece of steel to divert water out correctly at corners and not enter center (never mind to complicated to explain). But hatch feels lighter.
Will epoxy prime well in there. Set 3-1/2" long hatch pins.
Ready to remove Hatch now along with heavy rear glass.
About another 10 hours getting everything right for this step.
Will let Ducktail filler cure a week or two before finish sanding / priming and start the hood and remove the fenders.
Now remove interior, evaporator and remaining AC refrigerant lines. Catalog everything in boxes and sandwich bags etc.
Have a great weekend everyone and thanks for the encouragement.

Definitely doing it to make the exhaust as short and light as it can be. It also screams the motor is up front. But that is a good question. I got a 'classic' tag and not an 'antique' PA plate. I didn't go for the antique plate even though it would mean no more inspection because it looks so dopey with a Model T Ford up in the corner. They ruined that plate. Classic tag means i have to be inspected but no emissions are required.

Regarding the side exhaust, would be very cool to 'ape' the air cooled RSR rear torsion inspection plate opening and have the exhaust exit there, but not about aping 911, this is a superior Porsche. I compared the stats of the early 90s RS America to what i will have. RSA weighed 10 percent less=2900 lbs and had 250-260 HP and 220 lb.ft. torque. We can beat that! I was day dreaming about driving it to Carl when complete and letting him make it a true RSR in the motor/trans department.

Thanks Tony, means a lot, you're the Form and Function Master IMO.

Thanks Rocket Man!

Nice job, Matt. You are doing what some of us only dream about.
Thanks for all,
Dave

The Fixer

Dave, thanks.

I hope you and the Family are well.

Thanks again for the help with my VDO instruments, your spare circuit board will be on a shelf in my garage if you ever need it.

Best,

Just wanted to document wing shaping (to 150 GT) needs another couple skim coats.. More adjustment to hatch pins and weld pin mounts to rear,
adding a small 3/8" x 3" nom diverter in bottom corners of hatch frame to ensure no water gets to the dry side of hatch seal. The hatch drillings will be finished with file to look neat and symmetrical. Side drilling will be exposed but center area will be covered with interior panel and not seen.
Found aero mirror covers with Porsche emblems i never used on the IROC 911. Tony 77 i know you have these mirrors, they're yours if you want em, PM me.

MjRocket

Hey Matt

If Tony doesnt end up wanting those Areo covers let me know, i could use them as i just installed a used set and there the wrong color. Gave them the rattle can treatment for now but not the best match. The covers would be a good band-aid till i can get them professionaly done.

Thanks

I think your duck tail looks a tad on the small side. The duck tail on the 911 is a little more pronounced in comparison with the overall shape of the car. Of course, I'm not sure that you could have made it much larger without it looking cartoonish, since the vertical height of the 911 duck tail is appropriate for the more pronounced verticality of the 911.



You want to do lunch sometime? I'm up in the Wilkes-Barre area, but my son lives in Warrington and my wife's family is across the Delaware in Jersey, so I'm down your way two or three times a month.
