I hope it's not your daily. If it is your probably going to blow it when you least expect it and can't afford it. If it's not your daily it will probably live just fine until you get the new motor built. Gotta love Murphy...
Edit: What's the difference and advantage of going F-1C over the F-1A? I was thinking of doing the F-1A on my car, but I'm curious about the F-1C.

I have a D1SC at 9psi and put down 653rwhp/546rwtq and its a stock block and heads. Stock internals except the cam. I drive it 4000 miles a month and it has 53000 miles on it. No probs yet. It's getting meth this summer and should be around 720rwhp

But the person posting is running a T400 which will put alot more stress on the motor/blower combo which would lead to failure alot quicker.I highly doubt the 5" pulley will strain the motor,so with a good tune it will last a real long time.The downfall is the blower will be way under it's efficiency for now.

Who agreed to tune that big of a head unit on a stock bottom end? Lol. The meth is going to buy you time but I don't give it six months. I hope I'm proven wrong but I remember seeing a Corvette owner in Europe who ran an F1-A on a stock motor with comparable octane (XX Ron) blow his engine up. He even ran D1SC pulley's I believe to run lower boost.
I would just drive the engine without the kit installed until you have a built motor for it.

I run a 4.75 blower pullley and 8 inch crank. With a f1c my stock ls2 bottom end is holding up fine but I do. Run it on the a/f rich side . With a lot of meth injection. Being beating the crap out of it for over a year now. Don't worry put the kit on and save for a rebuild cause it will need it. But not right away if the engine is good.

I do have a meth kit going on it. ordered 5" pulley today. still waiting on a few parts. going to mount the supercharger this weekend hopefully. i will try to get some pict of the car this weekend. it looks pretty good. but that does not help the motor last any longer lol. oh well it should last a little while with a safe tune.
