From Wiki...

. Although originally approved by the SCCA, they succumbed to pressure from other teams, McLaren in particular, who argued that the fans constituted "movable aerodynamic devices", outlawed by the international sanctioning body, the FIA, a rule first applied against the 2E's adjustable wing. There were also complaints from other drivers saying that whenever they drove behind it the fans would throw stones at their cars. McLaren argued that if the 2J were not outlawed, it would likely kill the Can-Am series by totally dominating it — ironically, something McLaren had been doing since 1967.[5] A similar suction fan was used in Formula One eight years later on the Brabham BT46B, which won the 1978 Swedish Grand Prix, but Brabham reverted to the non-fan BT46 soon afterwards due to complaints from other teams that the car violated the rules. The car was found to be within technical specifications allowing the victory to remain.

I only attended one Can Am race held at MIS, think it was 1970. My main memory is that my ears rang for two days after.

 

what really ended Can-AM was the Porsche 917-30 twin turbocharged flat 12s, dominated every race in 1974, turbo cars ended all other forms of racing also!

it took 35/40 years before any one could make a BB Chevy stay together with serious turbocharging, today those old fashioned design BB are makin 2500/3000HP, (but not much is factory stock in them also).

 

back on topic, my 1975 XJ12C , V12 manual transmission, real knock wire wheels(no Lug nuts).

 

And what a topic, too. You own a beautiful automobile. My first Jag was an XJ12C. Bright red with the black vinyl roof. Absolute fantastic machine. Made the mistake of selling it when we moved out of Colorado. The gentleman that owns it now is doing a complete ground up restoration. My wife still chuckles when she thinks about the line in the manual about keeping the fuel tanks balanced when traveling at speed.....

 

.

right about the two fuel tanks, i learned the hard way , fill both full up, and then parked it overnight on a hill side, it dripped gas all night from the low side!

good thing nobody was smoking around it!!LOL

i do not really like two tank systems, had much problems with some twin tank trucks, and system getting fouled up on change over.

pic of my XJS fuel tank system and pumps,ETC.

 

.

alyn nice vids, i particularly like the on of the 1950s Indy cars ,#31 race car from City of DAYTONA BCH, that is one of Smokey Yunicks cars, i knew him personally, many talk sessions, he was a very kool guy, and he told many stories about racing and WOMAN!,LOL

he was good friends with Jim Hall, Chaparell cars

 

that is actually not the sucker car (2j) pictured in either photo.

since we are on the subject of can am cars at the mitty. craig Bennett nearly lost his life this year in the uop shadow...approx. 1100 hp can am monster. craig is a very well known and capable racer but these cars raced in anger have taken some great souls

 

here is an in car video of craig in the shadow dn4 on a better day. ferocious!!!!

 

Were those wires factory? Or off an xke? Very nice 12c!

 

I actually left Sunday not knowing what had happened. There was a long delay and we knew it had to be a pretty bad accident. Saw the car later on a hook. Hope he recovers quickly.

 

good guess, YES they are 1974 series E type(XKE), with all the axles ETC ,and bigger brakes&calipers, 3.54 gears, hi/bias LSD!

all new Michlin tires .

i have a Jag friend has a 1967 XKE roadster with a set on custom made full STAINLESS STEEL wire wheels,(can i say expensive)!!!

 

Eureka!!!


I got my Harmon Kardon stereo and small amp to work on the XP
powered Dell my son gave me. USAF surplus!!! Yowee, awesome sounds.


1. I saw one of the tech's on the CAnAm car pass a hand over the vertical pipes. feeling for heat to denote all 8 firing, I think!!!


2. The big sound change from snap, crackle and pop at "idle" to the silk ripping shriek at speed. Fabulous.


In the early 70's son and I often went to a historic old race track at
Saugus, Ca. Wifey and daughter opted out??? Concrete and just short of a 1/4 mile. Only slightly banked. Two classes. Somewhat stock V8's
limited to just short of 400CI. Mostly mid 50's SBC's. One 60's Tbird.
I think it was just mounted on a 3/4 ton chassis. Hugely heavy, but almost capable and sounded great. The fastest and loudest was a 60's mopar sans top. Real thunder as a pack of V8's charged down the straight at WOT!!!


The other class was for 6 cylinder cars. CI limited to just under 300.
Again more mid 50's Chev's, but, one or two Fords. One of the fords was suspiciously fast. Great noise as they screamed down the straights. But, much different sound. Son coined an apt description,
"Mad bees".


Track now closed. Houses came,. fussed... Gee. Buy a house use by a race track, what do you expect????

Road America track,scary fast, i was there in 2007, the last time they run the Audi Diesel car!

the diesel car would blow past PENSKE factory Porsche cars on the main straight like they were standing still, he promptly had them banned.

Porsche engines were screamin at 10,000 revs, Audi diesel was revin 4500/5000 rpm,and quiet to boot.

quite a sight to see!

since then FIA and other organizations have regulated them out of contention, to many restrictions, and strangled the potential of a diesel for racing purposes!

like Can-Am they have faded away.

 

Wow, I'll bet that 12c pulls nicely with 3:54 gears, got to be a really nice drive! Spokes may be worth the fuss if they were stainless.
