An auto would really bring out the car's potential, but I am more impressed when I see someone shifting a 9 second car like he is doing. I would rather watch the 9 (or maybe 8 second by now) Supra shifting gears than one coming off the line on a T400 trans with a trans brake. Takes all the fun and skill out of it...

Interesting, I never heard of those numbers is that at a 1/4 mile track or Guesstimate's? Please by all means post more info on those numbers!

That was the road and track test of the 935/76 chassis with rounded rear flares, 8.9 was the average of 3 runs with 8.4 being the fastest. The driver was the road and track magazine test driver, no fudging of numbers as Porsche wanted the world to see it's potential. R&T had the car for 3 days to beat the hell out of it to see what this new group 5 effort was all about.

The numbers were quite real, as they were done the 'old fashioned' way with the time/distance calibration wheel (remember THAT archaic thing that R/T used to stick on their test cars for acceleration data, LOL?) and verified by Germany's Auto Motor Und Sport in the same way. I'll see if i can find the article.

i hate to break the bubble but 8.90 @ 134 does not compute. You would need atleast 150mph to do that.

And if road and track did it I put even less value in it

I'm having some difficult with those numbers and the way they were obtained, that's based in the following points.

1. The mph 134 seems awful low.

2. If the numbers from road and track are as good as the estimated MPG on the new cars then we are in trouble

Well the 935's were/still freaking fast. I think it all depend on which teams 935 we speak of too and the state of tune it was in. Beyond that, the 935's were pretty much tubular chassis, I think some might of run semi-tubular but I mean you're no longer in the street car catagory.

Production and Race are a bit different boys.
Gotta run.

I sat in the car they did this in, it's 98% production chassis. 935-001.

Regardless, we are just starting to pick up on the power and potential that the speed shop guys were making 30 years ago at the factory.

This isn't rocket science, my 3.8tt is aiming for 1,000 hp and it's nothing that special. No secrets, just how much $ you want to spend at a good shop. It doesn't have to cost a schit ton if you get people that won't screw you over.

Well Noted............ However the 935s were in a league of their own, no questions about that

No long ago, High HP Porsche's was a Tabu in the Porsche street world, that has changed tremendously starting with the newer turbo technology and the blessing of EFI, now the question remains how fast can this ( Bello) street car ( or any other 911) really go in the 1/4 mile, for sure this is far from been a finish chapter.

935's are just 930's with fiberglass fenders, big turbos, big tires, and an aluminum roll cage...nothing too special. Kremer put a couple on the street back in the day. it was only tabu in the states.

Saying a 935 did ____ in the quarter mile doesn't mean much of anything because the teams changed gearsets in the transaxle for every track they went to.

Shorter gearset ratios for faster acceleration off the corners on the tighter tracks and looong gears for tracks like Le Mans.

Maybe it was geared very low for tight tracks and just wound out right away? Hell if it got to 134almost instantly (and stayed there) that would be around 7 sec 1/4 mile.

well then bellos 9 sec 1/4 doesnt mean anything because he can change gearsets just like the 935 teams could.

I think it should be interpreted like this: Even with crappy roadcourse gearing a 935 can run an 8 sec QM, thus they are fast cars.

Thats true and there was never a tube chassis 935.

The very last ones made were getting closer to a prototype chassis with partial ground effects tunnels replacing parts of the floor pan.

Unfortunately the boxer six 935 motor being a low wide engine that is great for low center of gravity made it impossible to have big wide ground effects tunnels, while the competing V8 cars had alot of extra space for those tunnels on each side of the motor because the engine even in dry sump configuration wasn't nearly as wide down low.

Thanks for the history lesson, even though its irrelevant.

I have to do some digging, but I have the Road & Track where they did a comparison between a 930, a 934 and a 935. The performance figures that were given, were actually extrapolated from the data logging(?) the factory engineers did at the track the comparison was done at, if memory serves right. The numbers thet quoted did not make any sense to me either and extrapolating from the information given, their "quarter mile" was 150-200ft shorter than most. The car also had very short gearing, in the neighborhood of 180mph. And the 590HP (935/76, car pictured above is later model twin turbo)was rated at 1.3(?) bar boost, which they well exceeded in qualifying. But according to one of the professional drivers of the car, when they were at tracks that had F1 cars practicing at the same time, the 935 would actually pull them on the straights.
I think that Porsche wanted everybody to know that their cars were fast, but not give any real numbers to the opposition.
