Guys,
This morning while walking my dog I was thinking about my little 67 with 160hp and weight of 1030 (well, since I have a sunroof coupe, the weight is probably more like 1050).
Anyway, I was thinking more about that chart that someone posted a few days ago which showed a comparison of hp/rev's between the 911R and the 911S - and how that curve goes almost vertical to 8k rev's for the 911R versus the 911S which peaks in the high 6's. As I thought about what it would be like to buy or build a engine with more hi rev'ing power up top like the 911R (unlike the RS), I started to think about how expensive the cost of building a 911R engine would be - and how unsuitable for street use a 911R engine would be. Then I started thinking about going with more streetable cams etc. before realizing that my best bet was to go in the opposite direction and try to get extra power by dropping the weight instead of increasing building a higher hp engine!!!
Here is what I figured:
My 1967 911 coupe weighs around 1050/ hp 160. That would mean a hp to weight ratio of 0.152
To come up with the comparable horse power to weight 210hp that the 911R engine (and 911RS) produces, I calculated that I would have to drop 210 lbs. That's relatively easy if you toss out the passenger and the passenger seat (even more if you have factory recaro sportseats). But if you are driving by yourself, where would be the best place to save the weight - for the cheapest amount of money? In other words, how much weight could I save by swapping out steel for fibreglass fenders in front and hood and engine lid? How about changing to plexiglass in the front and rear windshields, and plexiglass quarter windows. How about going with 911R turn signal and brake light assemblies all around?
Don't get me wrong guys. My 67 911 with 160 is plenty of hp. I am just looking for ideas from others who have experimented with trying to bring down the weight on their cars (but still keeping, heat and other daily driver luxuries). I figure,the less it weighs, the more hair raising the driving experience would be....
