2018 RULES ARE POSTED!

2018 Rules: http://www.racewrl.com/pdfs/2018_rules_draft.pdf

This is the Draft version open to comment.

There are minor revisions for next year, here is a quick rundown of the notable changes:

1. Appendix B has been completely reorganized. Teams may now class by dyno or factory HP
2. Teams may voluntarily add ballast (with restrictions)
3. Fuel cell capacities must be clearly marked at the fuel port
4. Team must complete 50% of class leader lap count to score official finish (dropped requirement to take checkered)
5. Clarification to cage rules regarding attachment points
6. Width extents added for body and tires

Note that the changes in Appendix B mean that you can now class either way - the original system or by dyno results. The original system is simple and costs nothing. The dyno system requires minor expense and hassle but might be preferable for some cars "on the bubble" between classes.

Minimal, straightforward and logical changes, well done.

I think it's safe to assume that teams will chose the method of determining HP that if most favorable for them. Is that the intent or should they have to take the "higher" of the two values?

Great job Joey. This fixes concerns I had about engine mods that improve reliability and serviceability but not performance.

We recognize that some teams are running 100K-mile stock engines that may be down on power, against teams that can afford to rebuild motors and maybe even *ahem* slip in a little grinding and de-flashing. Of course no one would do that without disclosing it! So in theory you can have two identical cars but one putting down, say, 10% less power simply because the other team can afford the money and time to keep a motor fresh.

Instead of forcing teams to spend more money on rebuilding motors every year to stay competitive at the top of their class, we've created two opportunities that are very cost effective by comparison - dyno results showing actual power output, and ballasting. Teams at the bottom half of a PWR range in their class can elect to upgrade their car to move closer to the top of the PWR range, or, they can use actual power output and perhaps ballast if needed to move down a class and compete.

The limits on ballast will keep cars that are mid-range and above from "trophy hunting" in lower classes.

Width extents - can you helkp me understand this rule, and specifically if adding fender flares that stick out more than 3" per side are now against rules?

As you know, we run an Opel with fairly ridiculous flares, they are well over 6" wider than stock body - this has never been an issue until now, just making sure we are still good.

Thanks

The Opel is the best sounding car in the WRL! Not obnoxiously loud just a great sound.

Which brings me to my rules comment. Would love to see some sort of noise restriction that is across the board regardless of track. Having to wear ear plugs in the pits because of a few just ridiculous sounding cars gets pretty old.

Generally speaking the fastest cars on the track are well prepped with a complete exhaust and have a great sound.

Loud does NOT equal fast!!

New build head scratching, continued from the tire thread that started making me curious...

I like the idea of mod factors for specific tire models like NASA. I've been calculating a new GP1 build and the mod factors are really making me scratch my head as it seems the penalty isn't proportional to the cost or speed benefit and doesn't account for the original platform (handicap, base classing) at all.

I could be misunderstood, but I'm trying to figure out how to get the power where I can still fit GP1 after the mod factors that are required to give a Mustang a chance to compete with a Boxster.

As I have it calculated out, I'm showing a virtually stock Boxster (-0.2 for basic shocks, if they even upgrade over stock at all??) can have 213whp @ SpecB weight of 2450. My Mustang after mod factors (live axle, needs aero and substantial suspension to have a prayer) can have an extra 10hp for 223whp @ ~2700lb (Fox).


I realize the 2018 rules are done now this is more just food for thought I guess. And maybe I'm just stuck and shouldn't be building a Mustang if I want to play my cards best, but damnit I'm a Mustang guy. :lol:

I'm guessing a newer IRS Mustang would be able to get away with quite a bit less mods, leaving more power to compete based on the rules of today, but at a much higher initial and operating cost (ala Boxster).

I love the WRL format and watching it evolve and am looking forward to 2018 regardless of coming up with a 10/10 build or not.

You could detune the car to 210hp and use the extra room for modifiers for aero and shocks. Less power is easier on the rest of the car which means more finishes and hopefully wins.

Personally I will take handing over power any day, but I drive a Miata so that is all I know.

That's the plan for now, just hoping it's enough!
