Why so low!!! Honestly I'm hoping for over 600 I'd be happy with mid 5s. But the sc rpm should be around I think 52k so the hope would be 16-18 psi. The latter not coming until I get a 3.12 but with a 10% od and 3.12 I'd be around 55k rpm on the sc at 6700 which is around where I guess I'll be shift 67-6800

I hate you yea that's the only thing I'm really worried about but it was 8 run swap or water meth. So I chose water meth lol
Does it help that it's the same upper pullie before when I had no slip at 6k? Larger lower, for better traction...I'm hoping it's not too bad, although from what I've read seems to be a bit hit or miss on belt slip with our cars, not sure why that is?

I wouldn't imagine you would have much belt slip with the 3.33 pulley. Having said that, you probably wont make more than 11-12PSI and so I wouldn't guess you make more than 470-480rwhp range. On a smaller pulley you should be able to make upper 500's through the SI Trim.

I was going off rpm of the sc to get boost. The cams and intake should put my power production around 6800. I made 8 psi at 5800 before the overdrive crank on this sc so I would hope around 6 I would have 11-12psi the plan would be 16-18 6800 but may need a 3.12 pullie to make the 18, but I would think 16 or so around 6800 without belt slip. You guys are depressing me! Lol

Blower cams and ported heads are going to see your boost drop. I was making 10psi through my supercharged setup at 6200RPMS. Gain another 1-2 through 6800RPMS puts you at 12psi. Overdrive pulley probably gets you to 14-15 but the heads and cams drop you back down to the 12 range like I figured. If you hit 500RWHP on a 3.33" pulley I'd be very surprised. On 16-18PSI I have no doubt you will be in the mid to upper 500's though. Just don't think you will get there with a 3.33" pulley.

You bring up a good point of reduced restriction. I guess I look at it like this I'm using 94% of the capable rpm out of that supercharger so that being said not sure why I wouldn't see 16ish and 18 if I saw 100% rpm assuming the max rpm of the sc is also the max flow at 1150. That's all I was saying, if it's possible to make 18psi with heads and cams from that sc why wouldn't I be getting 16 from what I have? I've seen other people running a 3.12 upper getting the 18 from a si trim. Guess I'm just worried I spent all this money and I'll need a ysi to break 600 on pump gas.

Keep in mind you are running lower than stock compression as well (need more boost to make similar power). For the record, I made 622 on 16psi on e85 through a turbo. Think of the 2v motor like a Supra motor. You need a lot of boost to make impressive power levels. Also, 16PSI is a little more than 1 BAR so you are going to be making a little more than double your NA RWHP. I would guess NA with the way you're setup you are probably making 280RWHP. My guess is on 16psi you would be close to 580rwhp.
