Had planned on going SC for the track car. I have the full kit already, SOS with larger HX, V mounted with oil cooler in front on Mr Sideways rad. So, Inline pro owed me a favor and was really nice about pricing an f24 build. Never considered it but it sounds attractive. I know there are issues with SC on track cars but I think I have it sorted out pretty good. I only tracked the car twice to shake it down before I was going to put the blower on this winter and I have to say I love how it drives NA. I really like the smoothness and being able to drop the hammer mid corner vs having to pedal it on a boosted car (Im assuming thats the case from my 01 street car thats SC). I know its not the same peak HP and wont be the same in the straights but Im starting to understand it may be more usable power around the track and in corner exits. Just dont want to feel im lacking power after spending all this $$.
Thoughts/experiences?

Sounds like you are already set up for a reliable track sc set up. How much you boost will dictate your experience regarding reliability longevity along with how your power compares to the F24. Most avid track abusers with SC I know stick to no more then 10-12psi/350-380whp. At that level you are going to exceed output significantly all but the very bottom end under 5k rpms, which on the track if you are driving properly, you never dip into so that's moot, and purely for streetability. Evn a base 6psi sc kit will exceed peak power over a basic f24, however not deliver the trq curve. Modulation on the track isnt going to be much different then a NA car, because there isnt a significant trq increase. Responsiveness is the same as NA because you are sticking with Air to /water cooling.

Or why not just go for the F24 along with your SC?

There is the twin screw SC kit on an FI thread that would produce power across the rpm range.

In theory yes, that's the idea, but we don't really know what its going to do yet since this blower type has never been mated to our engine and the kit is still under development. It could be a flop in the top end for all we know. A centrifugal on this engine makes for a great track set up though, that we do know, and mated to an f24 would bump up the low/mid range a substantial amount, comparable to a roots/or twin screw on an a f20 at similar boost in that rpm. The OP Already has the centrifugal SC ready to go. Id just slap it on and run it, if at a moderately appropriate boost level it still leaves some to be desired in the mid range tq department then opt for the f24 and throw the centrifugal back on.

Budget dictates one or the other but thanks for the response. I was thinking the same thing. It has a 3.4 in pulley in the kit now but I'm going to call SOS and get the stock size to start out and see how it fees and more importantly how the temps held. I just love na but it's costly and would hate to be left wanting

I've seen the posts on FB about the whipple. It seems they only have it mounted and are still developing. I dont believe they have addressed bost cooling yet either.

Just use what you got now, save the shop credit for when your motor lets go and get a cheap rebuild from them.
