Indy Racing opens engine specs to anything up to 6 cyl and 2.4 liters
That has every one wondering including Honda, Ford, Cosworth and MAZDA

It goes on to talk about the Trouble the MZR-R has had and whats been doen to fix it for this year.
Personally I can only think of one thing- a SpeedSource Indy Team

“It’s exciting news but it’s so wide open and there are still some major questions to be answered,” said Ian Bisco, the former racing manager at Cosworth. “Will there be a RPM restriction? Will it be an air flow restriction or a fuel restriction? Will the engines be stressed or a non-stressed member?"
Honda, which reigned in the turbo days of CART and won six consecutive championships before moving to the Indy Racing League in 2002, had been pushing for a V-6 turbo, publicly stating their lack of interest with an inline-4.
“We’ve been in an open and engaged dialogue with the league now for two years,” said Erik Berkman, President of Honda Performance Development. “And the whole idea of trying to come up with something that wouldn’t exclude anybody – but you have to exclude something. Are we going to allow rotary? Are we going to be able to bring a Honda jet turbine-powered car back to the Brickyard? The idea was, I think, to embrace a range of solutions and I think the league is still going through that process, as you know, with the chassis manufacturers still holding court.

Mazda, the power source for Formula Atlantic before that longtime feeder series closed its doors this year, has made it clear it wants to be involved in open-wheel racing, but they are said to be waiting on more feedback from Bernard’s group.
Compared to a Ford or Honda, Mazda is known to work from a much smaller budget, and based on what ICONIC envisions for 2012, Mazda will likely wait until all aspects of the engine regulations are spelled out until reconnecting with the series, whom they met with last week in Indy. If large financial commitments and big engine production requirements are put in place, look for Mazda to pass on 2012.
If the Series is smart, they will address a sliding scale of commitment – one where smaller manufacturers and even independent engine builders can compete without being drowned by the cubic dollars an engine giant from Detroit or Germany can bring to bear.
Provided they are interested in participating, Mazda is one of few marques who could answer the call for 2012 with an existing product. Their 2.0L MZR-R sportscar engine, now in its fourth year of service, already uses alternative fuels with BP’s Biofuel Isobutanol, and generates 550hp with a large air restrictor. Without the restrictor, reaching the stated ceiling of 700 hp would not be an issue.

I think a g/s airflow ceiling would be awesome. Do away with engine design limitations outside of safety, and simply limit the mass airflow. Indy provided sensors to keep everything on a level playing field. It would allow rotaries, forced induction, big displacement NAs, etc...

There are still many details to be released however its clear that Randy Bernard is taking the Indycar series in the right direction.
Watch for more details in the coming months.
Fuel will be managed with a maximum flow rate device. There is still some work to do on this feature however its a key component. Boost will not be regulated and 2.4 liters is a maximum; if someone wants to design around smaller displacement they can. There may be a sonic control on the airflow depending on the final configuration of the fuel flow limter. Expect to see an Indycar average 5 miles per gallon on ethanol.
Rotaries will not be allowed in part due to stipulations on some of the materials used. Even if they were its pretty unlikely they could make enough power on the fuel flow limits.
Engines will be a "semi-stressed" member; that allows them to either be a fully stressed member or not.
A spec 7 speed sequential gearbox will be used that allows separate rear suspension pickup points to be bolted onto it. The gearbox will be made in America. Possible vendors are Webster and Fairfield.
The cars will shrink to about 7/8's the size they are now. Front tires will be have wider tread and carry more weight. Rear tire tread width may be reduced.
The chassis will be made in America. There are some politics going on over that decision as the intent is to maintain a US base for teams although there is an intent to include races in Europe, Asia, and a return to Australia.
It almost looks like Randy is taking a shot at Bernie's turf one step at a time. Judging by the global economic cycles he could be in the right place at the right time. Its no secret that the F1 circus is embroiled in a political upheaval and Bernie won't live forever.
Its going to be interesting to see how all this unfolds over the next 5 years.

This would make this series kick ***....I really hope its as open as we would like it to be. The only thing that could make it better than that is Juan Pablo Montoya coming back to it and winning it again, hehe
