Man, where can you get it for that cheap.......
I was going to get one, but then I would have to do a custom mounting bracket and that would probably result in me switching the pulley setup........I went with an F1 since it fits the brackets I have already......

Man is this a new head unit,rebuilt,or used? $1800 is at least $1000 under dealer cost.
From what I have gathered, it's like Bos said, you'll need a different bracket set-up at the least.

nope you won't need a new braket. trust me i know. you might need a new intake hat set up though.
is the unit used? cause that is cheap.
now why don't you pulley up the current head unit and save the $1800 for something else?

from what i have gathered so far is that the f1 is a more efficient blower at high goost, i have also heard that it is a much more peakey blower. i just want to do my research before i spend the money. i would also like to have a M6 LT4 in the high 9s very low 10s. as for the intake hat i dont use one. just chicken wire 
From what i have seen in the vette community is that the F1-R will fit the D-1SC bracket no problems. At 16psi one guy got almost 800rwhp on a forged 346CID. So it looks like a good blower too me with more room to grow. I just hope u have a really low C/R so u can run 17psi on pump gas. I was going with 9.1 C/R on my car since I'm going to run the D-1SC, but after seeing this F1-R i might go with 8.5 C/R and run as much as 17psi on pump gas maybe with methanol/water injection after 14psi just for safety. I think 17psi would be the max u can get out of a F1-R since the vette guy got 16psi on a 346CID with a 3.8 blower pulley and i guess 7.75 crank pulley. Based on his dyno he ran the car up to 6600RPM... That means he is running the blower around 67000 RPM which is almost maxing out the blower. I guess they can squeeze 1 or 2 more psi out of it, but they will be overspinning the blower. I would be really intrested in knowing whats the exact crank pulley size(I hope is smaller than 7.75 so that means more boost for us).

Hmmm, I wish I would of known that the F1-R fits, I assume you are running one 1dirty, but I got hints of that in the past.......
Either way, I think the F1 will do plenty good for now

we are trying to finish my car up in the next two weeks, and it seemed like a great opportunity to upgrade head units, i havent had my d1sc for 100 miles yet, i had the p1sc internals changed. ill probably end up getting the head unit if i dont like it which i know i will, i could always sell it for a little more than i paid for it. i like this forum, most everyone here is helpfull, thanks everyone. Theres always room for more input. 
CFM rating among other things... check out this chart:

So your motor is 8:1? That's what I would do if I had to do it all over again.

good luck not getting belt slip. I have an 8-rib setup with an F1 pullied to spin the blower at 69,000. The most boost ive seen is 15 lbs. Id sell it in a heartbeat to have a turbo. Also the crank pulley is 8 11/16 and the blower pulley is 4 3/4.
