Yep, missed that. You win. We won't go into the "huge weight change" in 2005 that was just adding the driver...

I do agree the classes are wacky and so is the rule book. I should have said that before.

I guess no one knows yet, but I am wondering if the 818 can be gotten down to 1500lbs-ish with the 2.0l turbo motor?

Or 1600 with a larger motor?

One the 818 is in actual production, I wouldn't anticipate a problem with it being approved for D-E mod. I don't know the standards for kit cars in XP, but I suspect that they are much stricter, so I have no idea if it will also get approved there.

IIRC correctly DM was 1000lb without driver, that went to 1420lb for a modified tub 2L LL7 with a slight rear weight bias. Even I am not that fat.

The EM changes were not as drastic, and for the smaller displacement, no modified tub cars was basicly adding the weight of the driver to the old without driver minimum weight. A bigger engined car with a mod tub, the right weight bias had to add about another 200lb. Rather a big deal on a 1500lb dry car.

But overall I liked the change in weight, I did not like seeing motorcycle engines being outlawed just as bike engined cars were catching on with the Locost and kit car communities.

As for kits in XP, I would like to see standards, rather than backroom deals to allow some while excluding others. They probably have some, but I hate unwritten rules.

I would think XP would be ok with a "high production" kit car, which any Factory Five kit will certainly be, so long as it is bigger and heavier (ie: more than 1.8 liters FI) than a supercharged Elise, and doesn't exhibit some element of it's design that is otherwise more race-car-like than an Elise. So, no Radicals or X-bows or Atoms or Sevens or Beck 550s.

So, If you have it right, and I hope you do, using the normally aspirated engine might be competitive in D mod? Up to 2 liters is it?

All depends on the final weight on the 818, the overall dimensions and your definition of competitive, IMO.

Can it get down to 1200-1300lbs?   The 1420 for DM is with driver. 

In both classes, it *might* have trouble getting enough rear weight bias and might be too large of a footprint to be competitive (funny that I say that) for the top spots. 

I hope that it is able to be competitive in either class, we need the new blood and the cars are cool.

I sat in the 818R at Carlisle last month, and it is much bigger than the top EM cars, and bigger than my XP MGB (with a 55" minimum track width). It's well executed, and a very cool track day car, but I can't see it being competitive nationally in EM.

From what I have seen and read I don't imagine it can get to 1300#.

We may need to lobby to get into CS. (joke).

Why no 7's or 550s? Both have high production for a kit. And both are based on 50+ year old technology.

Too small and light for XP.  Or at least that's the impression I was given...  Things change though as members on the various committees change.  So who knows?
