EP, anyone? Options

[groot]

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?

210 is do able but it will be very hard in Production trim. In GT3 trim that is different story. I love Jake's attitude. One benefit with the 914 in EP is that the car runs with unrestricted suspension. This allows some serious suspension development but you are still limited as far as chassis and engine mods go. Jake you probably won't be able to make power much higher than about 8K. I feel that the 40IDFs or Solexes will act kind of like an air restrictor at high rpms because they are on the small side. I also don't think you can get enough compression with out messing up the chamber/combustion dynamics. Valve size will also provide a hurdle.

Now GT3 on the other hand? You can change things like rod ratio and valve size to take advantage of the other engine modifications, plus your not limited by carb size. I think you guys are looking at the wrong numbers in the search for HP. Peak HP numbers are for bench racing.

What happens when you get to your peak HP? You shift and fall back down below that peak. You must concentrate on transient HP. The faster your engine can recover from the shift the faster you can take out the competetion. If I have less HP and still out run you do I necessarilly need all the power at the expense of durability? Just some things to think about when you approach racing.

I have been over this on the GT2 forum, if you want to be a competitve threat to EP/GT you must be running Data Aquisistion, your chassis must be analyzed using something like CATIA, IDEAS, etc and your suspension must be anyalyzed and designed with assistance from something like ADAMS, CATIA, SUSPROG3D, ets otherwise you won't have a chance. You will be running against some very modern cars (Toyota Celicas, Mazda Miatas, Nissan 240s, etc). Some with factory backing. You will have a very hard time being competetive without approaching this from a racecar engineer's perspective. Gone are the days of just running a bigger motor. This is about the whole package.
