Silly single turbo/turbolag questions
To get max power from a given turbocharged engine, you need to use a big ****'d turbo...? When you use a big phatty turbo, you get big phatty lag... I know ball bearing turbos have helped, but not completely deleted lag. SO...that said, if you want 500-600 hp from a 2 rotor engine, can you get it with next to ZERO lag using a single turbo? (and I don't mean with a $10k inconel F1 turbo)
Hypothetical Question #2: if you were to use say 2 smaller turbo's in parallel, does the boost pressure stack/add? I mean, 2 T3/T4's running 15psi each equal 30psi?
If so, would that be better than a big turbo running 30psi?
and finally, which do you prefer: the Girlscout cookies or the Girlscouts?

simple rule of thumb, bigger the turbo the more lag. BB only helps out so much. turbo boost does not stack with two turbos. 15 psi is 15 psi, no matter if you have 1 turbo 2 turbos or 10 turbos. The only difference is that bigger turbos flow more air then smaller turbos.

That makes sense. And yes, I have much to learn about the miracle of boost.
All I want is a 450-500hp FC3S RX7 that's fun and easy to drive...is that so wrong?

Wow Ted, thanks for your insightful reply. In the future keep your smartass comments to yourself. If I wanted attitude, I'd talk to my mother-in-law. It's people like you that make a hostile environment on message boards. Let me offer you a piece of advice: GROW UP! While I may be new to rotaries and turbos, I am NOT new to fast cars and making horsepower. I have owned over 20 fast cars in my life. I have even owned a R33 GTR when I lived in Melbourne Australia. So the next time you want to look down your nose at someone and make assumptions, do everyone a favor: DONT. You are not any better, smarter, faster, etc than anyone else so get over it.
BTW: The girlscout question was s'posed to be funny.

Ted's Knowledge > Slipstream's Knowledge
I've said this before and I'll say it again:
"Watch your mouth, n00b."
And since you've edited while I was posting, I will also say: If you owned an R33, how the hell do you not know the basics of turbocharging?

My daughter is in the girl scouts, and I don't see ANYTHING funny about what you said.

Seriously, you might not want to get into it with some of the more knowledgeable people on the board.... might not get the answers you are looking for in the future.
To your post, I think your questions were answered. I will only add, that achieving 400 RWHP HP is not cheap, but there does seem to be a basic formula for it... Getting to 500 isn't quite as systematic, and takes considerably more effort IMO.
That said 400 HP in an FC is down right scary. You definately need to re-learn the car as someone else said. 470 is the most I've driven in an FC... and holy hell, I can't imagine much faster than that!!!
