Jason already had to blank out a bunch of stuff, there is no way they will release anything, unless GM says they can. And that is rare!!!

MadBill and Wnt2Go10o are right. We are forced to use the restrictors because we have an unfair advantage. 
On top of that, this year they have to add quite a bit of weight to the car. We have spent countless hours on our friction load test cell developing ways to reduce friction and parasitic loss on the engine to make the most of the airflow that we have. A 300hp electric motor spins the engine and measures the parasitic loss. We can therefore test different parts, procedures, and coatings to reduce the horsepower loss from friction and send more of that power through the drivetrain.

Hasn't Audi gone diesel with the R10, because they are allowed a bigger restrictor size in doing so (not to mention the theoretically better fuel milage).If anyone is interested, you can probably find the rule book here: http://www.imsaracing.net/
After a quick glance, I was able to see what GT1 cars have been homologated and any changes to the rules?

I'm not sure if he had the right to take the pictures or GM had the right to take them away (intellectual property, yet in a public place and uncovered).
its times like that, that i get kicked out of places because i wont delete pics just because someone says to....
ive been kicked out of pits, tracks, and even walmart...

audi wenbt deisel for several reasons. first was am inderpendent was doing really well last year using a heavaly modded V10 turbo deisel (from the big VW 4x4), thtas was untill the gearbox let go!!! the torque (about 850lbs ft i think) is insane and they think it will do another lap per tank which is a big advantage!
from what i have heard the engine is really good. very smooth and increadably quiet! so much so its hard for the drivers to hear what the engine is doing over the gearbox!
as for the restrictor size im not sure. but there is no dout they will come along and make them mod something if it gets a bit easy, a bit like they did the inlet manifold of the Prodrive 550 a couple of years ago, and the C5R intake aswell.

I just looked up restrictor sizes. In the P1 group, you can run two 39.9mm restrictors with diesel compared to 32.4 mm with a gas motor. This doesn't even count the fact to the gas engines are limited to 4.0L where the diesel can go to 5.5L with greater boost pressure.

thought they would just run restrictors like wrc do! then again the deisel guys would walk it with 1000lbsft + of torque in the mid range. run a veriable speed transmition (gona have to be big for the torque) or a DSG style twin clutch system and the gas fuel guys wouldn't stand a chance!

PS. i think i heard about Audi running particle fillters aswell! is this the first form of "clean" racing??????

Did anyone happen to be in downtown Ft. Worth today? i was there on about 6th or 7th street there was a small showing of the chevy racing team, they had the c6.r along with some nascar and drag cars they also had the ls7.r on display personally i didnt think it looked at all like a lsx at first glance because it didnt have coil on plug and the intake is just too cool for school those carbon fiber stacks are nice i also happened to notice the block was stamped katech (along w/ everything else) but could this be a new aftermarket lsx block in the future?

The LS7.R block will never be available to the public.
