28 Lap VPI Penalty - Can we actually be competitive?


Recommended Posts

Hey Champ Car folks.  Planning on fielding a well sorted e30 with a motor swap this season.  Doing the calculations it looks like we have a 28 lap penalty at the start of every race.  

E30 basic rating - 450

Engine swap - 106
Other modifications - 220
Total = 776

Couple of questions here.

1) Does the lap penalty adjust for track length or duration of race?  Would seem at a shorter race (7 hours) or a longer track the penalty is much more severe than at a 24 hours race or a very short track.

2) Can we actually be competitive with this car?  Are the winners coming in under 500 or is everyone starting with some amount of penalty.

Thanks,
Geoff

1) Sorta, it's in the rules. I think your lap penalty is doubled for a 24 hour race. The "standard" lap penalty assumes a 7-8 hour race.

2) No. Generally speaking it is suboptimal to exceed 500 points. With few exceptions, you just can't make the car that much faster that it benefits you more than the lap penalty hurts.

 

At Road America we do something like 160 laps in a race, and laps are roughly 170 seconds (2:50), so after some math, you would need to be turning 2:24 laps to finish even with us, and that's just not happening.

 

What other modifications do you have adding up to 220? That's a ton of stuff. Our e30 has the engine swap (currently 50 points) and no other point-adding modifications.

having built an insane e30, its super easy to blow the points budget. don't do it. you'll end up out of CC and looking for a home. my e30 is a GTO car in WRL, which sucks because you are essentially a pro race mode in WRL GTO at this point.

 

the new SCCA enduro rule *might* be workable for my car, and we will test that in december at the houston event, but for champ, stay in the 500 point box.

You can still race. Run it in EC no points to worry about but not overall results. Run as is and take laps(be sure to check current rules for values as these change). Remove some of the high point parts ie. big HP engine swap, coil overs, adjustable everything. If you are looking to bounce back and forth and BMW CCA is your primary series just run in EC and leave car as is.

Other points are from:
Aero 
Camber plates
Stand alone ecu
Fiberglass hood
Accusump
Oil cooler
Sway bars
Adjustable ride height

Read the up-to-date rulebook, ECU is free. Other stuff might have changed in points as well. That being said, no matter what you are way over on points. You should just come out and race in EC. Have a boat load of fun getting more seat time for the $$ than any other series. Race with zero penalty laps, you just aren't in contention for a podium unless there are 4 other EC cars in the race (which there probably will be), and beat all the other EC cars.

Just go race and have fun. I don't see how you could possibly overcome a 28 lap penalty. If you care about "winning" make it a 500 point car.

Do a race in EC, if ya like it consider dropping some points.

It looks like pretty much all of the parts other than the motor & Accusump are easily swapped within a night or two of tinkering.

-Get a spare set of E30 struts, mounts & springs for champ

-Get stock swaybars

-find a beat up stock hood

-remove the wing

-Use the OE oil cooler - zero points

-ECU is free as others have said.

 

That would put you at 6-7 laps down, which still will not be competing for the win in most races, but with a good strategy and drive could get you in the top 10 and possibly top 5.

Out of curiosity, what motor are ya running?
