I have a sneaking feeling that one O. Beretta is going to be rather chuffed to bits about this.

Hate to see Johnny O leave 'vette racing, but excited to hear about the Cadillac deal. I will look and discuss Caddys and WC elsewhere.

Autosport confirms in the print/digital edition that Tommy Milner will be driving for Corvette instead of Johnny O from next year.

I know it's been posted in other threads, but just for the record, it should be in this post because it regards Corvette's future. For 2011. Milner and Beretta in the #3 with Garcia for Sebring, Le Mans and Petit with Mags and Gavin in the #4 with Westbrook at Sebring, Le Mans and Petit. The story is here:

Corvette Sebring Test 2011 - Fastest (#3) and third (#4) in the final session. YES! Hope this is Corvette's year.

I am glad to see that Jake and the barbed wire are gone, but I don't understand the zoomie wedges on the back. I still think it should be red, white and blue.

arakis has a lot of promise if they can keep it on the circuit!
I have noticed in this years rules there is no distinciton between cars with 2 valves per cylinder and cars with more then that, last year 2valve cars like the corvette have been alowed to use larger restrictors then the ones perscriber by the ACO table. and it was writen into the 2010 rulebook. now in this years rules there is no mention of that distincion between 2 valve or more, that leads me to conclude that they will be forced to use smaler restrictors then last year, a drop from 28.6 to 27.9 witch is substantial,. does anyone know anything about this

Maybe because for years they had a separate table for 2 valve engines and the Corvette was the only car that would be affected by the transition to the new single table for normally aspirated engines.

From a quick look at the rules on the ACO site you are correct with the exception of IMSA E85/E10 rule which would allow a 2% restrictor increase for running E10. I guess the 5.5 liter max is on again, I thought they fell back to the 8 liter max, or was that just the FIA?

IMSA E85/E10 rule

well they had only one table but there was an eqution in the rules by withc 2 valve per cylinder engines calculated their restrictors from the main table.

here is an extract form 2010 regulations

For engines with two valves per cylinder and a single camshaft located in the cylinder block, the following

restrictors’ diameter must be corrected according to the formula:
D = {[D-1] x 1,034} + 1. The result will be rounded to the nearest decimal.

this is not present it the 2011 regulations

and if corvettes gets hit by this they will lose massive amounts of power.
only solution to the problem would be to grant Corvette a waiver, or for imsa to disregard aco rules and keep the old regulations for corvette, but that would mean the corvettes would be competitive in ALMS while at Le Mans they would be at a disentvantige

I’m not too concerned; I think the Corvettes will have more than enough power to stay competitive without waivers here or there. Although the recent rule changes do show the sanctioning bodies wish for the death of the large displacement 2 valve engines.

I am not so sure, right now they have a minimal addvantige, and not in hp but probably in torque, and if that is canceled, i wouldnt be suprised if they become underpowered.

If you look at the last season ALMS, corvettes were not the fastest cars, bmw's and Risi were usualy the fastest cars on track. Were corvettes absolutley shied was Le Mans, and even there risi was right behind on pace. any negative influence to next season compared to the last would not go good with them.

I think they will have their old restrictors at sebring, either by ACO suplimentig their regulations, or by ACO or IMSA granting them a waiver. because it would be sucide for ALMS to put corvettes at an disadantige

exuses, if you are implying, because I am a ferrari fan, I can tell you i don't care weather they have 28.6 or 27.9 since last years car 430 proved to be more then match for the corvette wining more races and generaly being faster! I am just sad as the show wont be the same, with them at an disadvantige.
