The problem with Indycar these days is that (IMHO) the damage done by Tony George is now virtually beyond repair. At it's peak, the cars had close to 1000 HP with turbo. They were tough to drive & separated the good from the great drivers.
Then came Tony George & his go kart powered IRL cars. Now, an individual who couldn't make it in CART could potentially be an IRL champ!
The turbos are back on the current Indycars but horsepower is still woefully low (around 600-750). IMHO, if Indycar is going to get any respect back, then the horsepower is going to have to get back to the 900+ range which will turn re-separate the good from the great drivers!
