So, there are some big changes coming in E-production (SCCA) to "equalize" the competition. In 2005, the 914-4 2.0L runs at 1870 pounds with driver.
Is anyone thinking of switching from FP to EP and using a 2.0L now that the 914 has lost 50 pounds? As you may have guessed, I'm considering it. Since I have 2-2.0L engines and no 1.8s, I'll be starting in EP anyway. But, I'm on the 4-year plan to get competitive (IMG:style_emoticons/default/smilie_flagge24.gif) , so it really doesn't matter immediately. I know they used to be competitive in EP. Anyway, there have been some posts about the horsepower a FP 1.8 can make. Any thoughts on a 2.0L? |

In the last few years alot of new things have been discovered that will make the EP engine a bit more reliable. I have one FP that has been alive on the same rod bearings for over a solid season of use. I have a few tricks to utilize in Groots engine if we end up doing the project, and I'm sure the benefits will be noticeable.
From what I have seen most people build race engines too tight, and that is simply why they don't last. I open every tolerance that I can except rod tolerances on the big end, but I do give another .0005 of running clearance on the crankshaft, and that tends to help rod bearings as long as you keep them lubed. The only way to go with an engine like this is dry sump, but I have modified wet sumps to work really well... BTW, I just found a new Tri-metal rod bearing for the 2.0 journal size... Should be alot heavier duty than the standard Kolbenschmidts or Mahles.. The only way to know if it can be done is to try, and I'm more than willing to do that. |
