Possibly not enough blow off valve. Add a second one. Or the new pro race one.
Separate lines to feed each of them.
Also a blower brace if you don’t have one already.

I ended up adding a strut directly under the blower to finally fix my belt issues. I was chewing up belts every couple of passes and with some help from folks on here that’s what ended up fixing my problem

Yes. I also have a brace that I bought from jake. Goes to edge of the blower and to the shock tower to preload the bracket. After the brace, I had the same belt for 2-3 seasons.

Check all brackets for cracks or rips.
I had the triangle that bolts to the head on sbf rip and I had to completely remove everything to find it.
Welded up and no more problems.
Run the brace also.
Denotation maybe taking place in your tune up.
That’s impressive for an F2 to make that much pressure on 600 cube motor. F3-121/123 is better for your big motor.

thanks for all the replies, i will put a brace from the blower to the shock tower and going to put another blowoff valve on it or use the pro race one , if that will be enough going to try to put a intercooler on it this winter it is making 250 degrees intake charge , even with the meth / water injection on full blast , yes its making some power, having some tuning issues but pretty happy with it so far
