Is the Backdating Fad Over?

Lol nah. When it had 85 hp it went 135 when I built it to 145hp it still went 135. Just got there much faster

That's awesome...

Hard to see how an old longhood makes the cut for any sort of regular use unless one is contented with putzing along. The G50 Carrera and newer, yes.

I've heard that heels against the road surface work pretty well (just ask Fred and Barney)!

I don’t think that backdating is dead. I still like the shape, but the 70s cars have a lot more issues. Putting the classic body on a newer car just make sense to me.

Remind you of what? Changed the headlights in 1996 - more than 35 years after the original "aircooled" 911 - on a pragmatic, Asian-inspired, watercooled, "in the spirit of" 911 that really is not a 911 at all. You mean that Porsche model 996 that was in all actuality designed by a Chinese man named Pinky Lai? You really cannot be serious. Who is they by the way? The bean counters at Porsche that saved the company from disaster?

Surely you cannot bring the 996 into a backdating topic.

Ghias had Até disc brakes in the front and drums in the rear. It was plenty for the weight of the car

69 Ghias couldn't do 135, unless you had some serious work done to it. Even then, it had to fall out of a plane to reach that velocity.

Hell, my 912 barely hit 120, downhill.

I assure you that it did. the 85hp was a 1776cc. Second engine was a 2176cc 145 hp. It took a lot longer to reach 135 but it certainly would, no reason for me to make things up lol. Car was pretty gutted and light. I think it maxed out at that speed due to the gearing and max rpms not changing between the two engines. One time i drove 135 mph in the middle of the night for about 15 minutes non-stop. I covered a lot of ground lol

I'm picturing him coming down the Grapevine behind a tractor trailer up to about 90mph and then popping out to finish the pull...

lol not at all. Did it quite often as i was a stupid kid. 85hp is a lot of hp in a light weight car.

You guys are brave driving a 912 past 85. I'm serious.

Still think your speedo was broken. Maybe with the second engine. Or maybe the exhaust fumes were fogging your brain.

Of course, I owned my 912 in the early 70's. You know what they say? If you can remember anything from the 70's, you weren't there. It's all a bit foggy.

dont remember the profile but the were empi 8 spokes on 145/15 and perhaps 185/15 rear. even with the 1776 engine i was destroying much larger hp cars. ITs all about the weight. As far as top end my 4th gear must have been tall enough combined with the rpm's to achieve it. Same tires, trans, and rpm's more or less for bigger motor so no surprise on the fact that its top speed was the same. That thing was a rocket. I won every single drag race besides one. Got a phat drag racing ticket at Dodger Stadium as well. That was fun. Car was scary on twisties so I stuck to straight line.

I would have thought so myself except the time it took to get from point a to b couldn't be disputed.

I was just giving you a hard time. Your numbers work. The reason I asked the question is because it was really common to put a low profile tire on a car like that, which messes with the speedo. But it's a free "final drive" improvement and improves 1/4 mi times.

4.12 final drive with a .89 4th, 25.4" stock tire size and you're at 134mph. I guessed at a 6500 rpm redline.

But, on the other hand, if you were running something like a 175/60/15, which is pretty common to mount on a fair of Fuchs, for example, then you're running a 23.2" tire. Now your top speed is only 122.8mph, but your speedo is going to tell you that you're tickling 135mph.

nice. I love knowing people smarter than me. Yeah was not running low profiles on the empis.
