73 IROC history question
 

Does anyone know which shop serviced the 73 IROC cars ? I have a '73 built 68S car with 73' wheels and I'd like to try to track the provenance if possible. The seller told me that the shop that serviced the race cars built my car. I don't know if that's true. http://forums.pelicanparts.com/uploa...1462850779.jpg

the first year of the IROC series was 1974 and the Porsche Carrera RSR's were1974 models. The series was dreamed up in 1973 though.

I have never seen an IROC Targa.

chances are the 1974 IROC cars were serviced by Andial. But that's worth an Internet search to confirm. Whoever molested that 68S should be shot.

As were the RSRs sold worldwide back then, the 15 IROC cars were built in house at Porsche IN Germany and delivered as turnkey racecars. There was no US conversion of street RSRs to IROC spec that took place.

The cars got RSR spec engines, but there were other things, like 5 lug wheels that were not RSR. They were kind of a hybrid between the street RS 3.0 and racing RSR.

Time to get out the tools and start grating the cheese off that body - hopefully you'll find a '68S underneath it all. That's all I have to say.

The comments about the IROC cars motivated me to go reread the section on this in Mark Donohue's excellent autobiography "The Unfair Advantage". Turns out there was one Targa RSR, which was the prototype for the series cars. The factory made it as a personal car for Roger Penske, and he used it as a daily driver for a while before giving it to his wife. I wonder if that car is still around.

Roger then ordered the 15 IROC RSRs directly from the factory as described by Matt.

ETA: And according to the book, Penske's race shop serviced the cars between races. The engines were sent back to the factory for rebuilds.

That appears to be it, although that certainly doesn't exactly scream IROC prototype, does it? That's just a 911E with flares and a Sunoco blue paint job.

It looks more like Porsche said, "hey, if you pull off this IROC thing we'll give you a (wink, wink) "prototype" for your own personal use."

I like it as is...... I would change mirrors, seats and possibly bumpers...... reminds me of Lar's 73S wide body Targa in S CA.

Along those lines, maybe the OP's car could become an interpretation of what the IROC Targa prototype should have been.

I'm a big fan of the Penske targa. Have been for years.

Thanks fellas. The seller tells me he lived in Loma Linda in 71, bought the car from a guy in Malibu , spent his dental school tuition to modify the car in 73. The wheels are dated 73. He says he tracked the car along with Donohue et al. He says it was a "customer car" along side the racers. I promised not to chop the fenders to get him to sell it to me, I might have to break that promise unless I can prove the story. If I can prove the story I believe the body kit is worth keeping . The wheels are 9's & 11's, RS style.

Keep your promise the car is interesting. Are those fenders ST fenders? What engine is in there? Post more pictures………

We cleaned up the engine, added hyd. tensioners and did the carbs and clutch.http://forums.pelicanparts.com/uploa...1462925087.jpg

When I found it on his driveway, he said magpies picked holes in the targa-top. I HAD TO BUY IT .
I need to change the seats.

I don't think those are ST fenders. Maybe actual RSR fenders but its hard to say.

I'll tell you, the car corners like its on rails. I lowered it along with my SC due to Texass advice.

Can I find anyone to ask from ANDIAL ? I read a little about them but I know much less.

+1 to that
But I doubt there is even an " s " under that atrocity .
