Anyone running a KB 6psi w/ all stock??

What about all the people with the cobra killer kit, they have no intercooler. I am really curious about this KB 6psi kit as well. I really want to know how it compares HP wise to the CK kit. Everyone says to get the 9psi right away but that is a big jump in price and not everyone wants to be that close to the limit of their stock motor. Personally the 6psi KB seems like it would be ideal for a daily driver and for someone who wants their car to last a long time. I just want to see more dyno #s from people with this kit, not just from KB website.

You should be able to run it safely at about 8 psi (just get the 8 pound pulley) on 93 octane gas i might add. I plan to get the 6 psi kit because im not going to have another 1100 to just blow on buying the intercooler. BTW, i checked with KB there is no penalty if you wait on the intercooler. It just costs the difference between the two kits ($1,100). Later down the road you'll just have to basically put the blower unit off and reinstall with the intercooler...thats the way i understand it.

none of them should be 303 (thats extremely low). You should get pretty close to KB peak numbers with vortech/paxton sc's.

I too am planning to buy the 6psi kit. The way I figure it, the 6psi kit with 4:10 gears should compare pretty good to the 9psi kit running 3:73 gears. If I take the projected tourqe for the 6psi kit and multiply it by the rear end ratio (4:10) it comes out pretty close to the 9psi kits tourqe multiplication factor at the wheels. I might also add that it should be a little safer on the engine since I would be running less boost. I would also think that I might get into boost quicker with the 4:10's

Well the truth is between 1000-2000 rpms your going to be at 90% of maximum boost already. The 4.10's are not going to 'get you in boost quicker' in reality. It will however get you in your engines powerband quicker which is always a good thing. 4.10's on a stick shift + kb instant boost is some mad tire spin lol.
BTW, let me know if you guys find out when tim's kit will be sold, the price on the intercooled & non-intercooled kits, and any other information yall can find out.
