Car is a lot more fun since all the little issues were sorted.
I am more than happy to help where I can, I am no expert, but have learnt a lot in the last few years.

Recently got quote for Whipple 2.3 + snout + pulley + bypass valve and was around $3100. Magnuson MP2300 (JBrady suggestion) with all included as Whipple, quote for $800 (bypass integrated) less. Not sure if will go with Whipple - need to deal with more complicated inlet, and price. Looks like Whipple can make more power, but some people claim that Eaton new design is more efficient than screw design ... I'm not expert ...

My goal for now is to use stock 1UZFE to make close to 400RWHP if possible (no inter-cooler) - daily driven car ... if price are not acquired please correct me.

I did initial measurement, looks like MP2300 will fit on manifold with no issues (Richwood manifold lower by 10mm), please correct if I'm wrong.
If I go with MP2300 few questions are open:
- what pulley size will be for 9-10psi and for 16-17psi (can stock 1UZFE handle 16-17 psi with e420c)
- will 6 rib belt slip @ 16-17 psi ? (using same configuration as current with M90) or need different set up ?

Making that much rwhp really depends on the heat inside the intake and how much boost the setup will have. If it's too hot inside the intake, then you can't make much boost to make more power. Not sure how much power you can make with this setup, but since there's no intercooler, be careful with tuning. 400 rwhp with no intercooler is kind of hard to get, but who knows.

I really meant to go with better supercharger, initially no intercooler, and to go as much as stock motor can handle.

I'd say go for it. But it's an insurance to put a temperature gauge to monitor the intake temp.

To put it simply, if you're going to go low boost, the Eaton seems to be more efficient. For higher boost levels, the Whipple is more efficient.
