How many data points are in your set?
Turbos were a major point of discussion all week. The CRB/STAC is aware of this issue. We had data boxes on all the major players all week and this will be one of our top priority discussions. - GA
The STU turbo cars can't be moved to STO -- Tucker qualified at a 2:15, compared to Huffmaster's qualifying setup of a 2:24 (in race trim Huffmaster only managed a 2:26 and Tucker a 2:17). However, the fastest n/a STU cars were in the 2:28s (although I believe Heinrich clicked off a 2:27 before his qualifying DQ and eventual retirement from the Runoffs due to a blown motor). So how do we even the playing field?
A possible answer is the STU turbo cars need a little weight to drop them to the 2:27s or 2:28s, where the super-fast n/a cars stand a chance. Then STU and STL could be reevaluated and many of the n/a STU cars could be moved to STL with additional weight.
The STL pace at the Runoffs was 2:35. My STU street ported 13B turned lap times less than 0.2sec faster than the front STL guys in the race (and the STL 13B ran 3 seconds slower). Wickersham went from winning the GT2 National Championship earlier in the weekend to qualifying 17th in STU in a Honda S2000 with a 2:36. Some n/a cars just can't be sped up to 2:27s or 2:28s, and STU certainly shouldn't be dumbed down to meet the lowest common denominator.
Adding 100-150# to STU cars like the street ported 13B and the Honda S2000 should leave them competitive in STL, and then remove weight from existing STL cars to speed them up.
Or maybe all of the n/a STU cars that are too slow for STU and too fast for STL should just move to EP.

EP 1990 Mazda RX-7 (used to be STU until the turbo cars scared me away, and STL rotary cars require too much ballast)

Is there a way to meet in the middle? Say add 100lbs to the turbo cars, and take 100lbs off the N/A cars. Try to get the N/A cars a little faster than EP and slow the turbo's down a little. I seem to remember that Eric's smoking time was in the high 2:27's, maybe a 2:27.8, so at best it's a 3.5 second gap.
Say Philip, did you catch RP's quip about wondering if you might be his editor?
STU BMW Z3 2.5liter
Forced induction cars in every series pose a problem. Just look at Grand Am ST. It's not about weight, it's about finding out how to limit boost/HP.
Stock ECU's and stock-ish exhausts are a key step.
I can tell you with a good deal of confidence that the fastest NA cars are closer to the T cars than you would believe. We have a diverse group of drivers/set-ups and a not so diverse group of cars.
We have data on 10 STU cars and 4 STL cars

Chris, not having access to the data you have, I can only speculate what your seeing. But I would respectfully call BS.
There is very little doubt that the turbo cars are much quicker at RA. Notice I did not say faster.
The only way this gets fixed is with limits on boost. Restrictors, tire size,and weight are all fools errands. In fact, it might be noted that Grand Am is going back to no restrictors, and boost limits( if rumors are correct) because they feel there is no way to control the turbos with restriction only.
Not sure what you guys are going to do to fix this, but I really doubt I'll be back unless I see something a bit more aggressive to even this out.
Pull the Restrictor, give the solistice a slightly larger turbo, reduce weight and give it 10 inch wide wheels..... it'll run STO times.
As for the Audi and the Miata. I'm not sure you could get either of those to run STO times without spending lotto winning type of money.
I think the big issue your seeing is that yes the N/A cars will see a similar terminal speed on the straights, but what's the average speed? The T cars are going to get there much faster and have a higher average speed.
