There are many reasons why the car would not be a great setup from a motor stand point. Running THAT motor at 14:1 (rough estimate on raised CR at 6psi) would not last long at all. Just my opinion.

The programs of the turbo and the cells are far different than that of a GT3. They can not be compared.
A rough estimate without all the numbers is for every 3psi you raise the CR 1 point.
I am sure this is a subject we agree we will disagree.

The formula i showed above is correct way to determine effective CR.. YOu cannot simply add .5 to the static CR to determine the effective CR. It works for a static CR of 8, but nothing else. As the static CR increase, so does the effect of boost as a percentage, on the effective CR.
Example: A static CR of 8 plus 1 psi boost will add .54
A static CR of 10 plus 1 psi boost will add .68
A static CR of 11 plus 1 psi boost will add .75
That is a HUGE difference from simply adding .5 for every 1 psi of boost. With 6 psi on an 11:1 engine, you would be off 1.5:1 on what the actual effective CR is. Screw up your timing settings and mapping based on that info and you're risking engine trouble.

The CR is not too high for 6 psi of boost and not all people track their GT3. I suspect we will see one before too long. What a beast that will be. You have to remember that driving a properly SC'ed car does not change the handling at all. The SC is only functional at or near WOT at which time the power is extremely smooth and linear as well as predictable. I guess we will have to wait and see if Todd has one in the works.

I drive a GT3 (actually 2 different ones) at least once a week, Just returned from a 700 mile trip in one last week. I agree that the GT3 (although less powerfull than my SC 996) is a great car and handlles great. The higher revs are great. I love it!
However, the discussion has turned to whether it could handle a blower and whether or not that would hurt the performance of the car. I take the stand that it would not hurt the perfomance in anyway and that a blower would make it one of the fastest Porsche'd on the road with everyday drivability.
But, we each have out own opinion.

The only people on this thread that I see advocating a blown GT3 are those that don't own one. Looks like the people that actually have one don't see the need for a SC, hence no one offering a blower kit for the GT3.

Yes, I know the formulas, obviously. As I said, these were ROUGH estimates and meant to give those reading this thread an average guide line to go by. Nevertheless this thread has gotten off track.

So, you assume that because some do not list all their family cars that they don't own them? Some of us like to display less pomposity than do others.

Anyone who super/turbo charges a GT3 motor is crazy, not well informed and completely misses the point of this car as it was originally designed by Porsche....imo

While you're at it, why don't you add a wet Nitrous system too?
And some neon lighting underneath the car, and some 12" subs to have a FAST AND FURIOUS GT3.
