It's not a straight x=y equation... you have to do power to weight ratios. Removing 10 lbs from a 4000 lb car is obviously not the same as removing 10 lbs from a 2000 lb car...
Assuming a fairly normal weight 914 and a nice 2056: 2100lbs/125hp=2000lbs/119hp, so dropping 100 lbs gives you 6hp. I can't show you the math right now, 'cause I had too much beer (IMG:style_emoticons/default/beer.gif) |

I can't show you the math right now, 'cause I had too much beer (IMG:style_emoticons/default/beer.gif) Lets see...my 75 with a 1.8 and early bumpers I believe was around 2200?????pounds. Now with a 300 hp chevy it weighs top and all 2360, which I thought would be heavier. So I added 160 pounds and gained 200 hp...that's a good deal, not to say all the hp is usuable. When I get the motor broken in I would like to find a dyno in my area that I could run both my stock 74 2.0 and 75 chevy 914 through and see how they compare. It wil be interesting to see if the chevy motor is really putting out the poinies that it was built for and how the torque curves look. I love my 2ltr, but it's hard not to smile when you mash the pedal on the v-8 and it roars to life. |
