Coming from rotary engines, I know that a 1.3L engine at 3000 RPM can spool a T66 turbo (66mm inducer) for about 500RWHP.. and by 6000 RPM will spool about a 90mm turbo (900 RWHP).. they have a very strong exhaust pulse..
Diesels have MUCH smaller turbine housings to help them spool the same kind size of turbo.

You're right that additional flow does require more shaft speed, but not a whole lot more... you can increase the flow by 50% but only need 20% more shaft speed to maintain boost

Did you see that 13b on youtube with a he351ve on it think he was getting 12 psi boost free revving engine.
I think a p ported 13b with a he451ve would be awesome.

I heard p ported engines weren't that good with a turbo, but perhaps some technology has changed.  I can't watch videos from home.

I used to work at a rotary performance shop, https://www.youtube.com/user/Rx7man/videos (near the bottom) you'll see a blue/green FD on the dyno, that was my car before it got dialed in and before the new engine... the white car was a 3 rotor putting about 750 HP down and burning the tires off doing it... one of my coworkers at the shop had an identical engine to mine, he put down 875 RWHP @ 45 PSI (race gas) and daily drove the car.. he had 50,000 miles on the engine when it cracked a housing at the track.. I also have some videos of a supercharged 12A engine.. perhaps 2 videos?  I know one of them was with a really bagged out old engine.. it was carburated, and with the orientation of the charger I had serious tuning issues.. fuel would puddle in the supercharger, making it need a massive accelerator squirt to not bog, and as soon as it got going it would stumble from too much fuel.  The new engine I built is the one that would go into the sprint car but with a turbo.. I was thinking a CT26 from a 7mGTE supra (buddy has one, with the manifold I built)

After going to arduino control i don't think a waist gate is needed.
around position 700 is my best spool. around 500 runs close to 1to1.
Have only gone to around 300hp, found my fan is kissing my radiator at high rpm. ::)

I have a piece of expanded metal grate in front of my rad.. Fan hub bearing came off once and thrashed it good.. next one a fan blade broke off.. again thrashed it good.. so I put it in there as a bit of insurance.. got tired of replacing radiators.

plastic blades are flexing over 2"to kiss radiator. started happening after i tightened the fan belt.
think i''l pull fan off falcon to put on ranger. ive been wanting a brushless fan for the falcon. use pwm to change fan speed.

wow... that's a lot of flex

Any chance of just underdriving them

Perhaps if you just had a fan that was either stronger, or had less angle it would work better too

Went electric had 1 sitting on shelf that would fit. Should help my ac during summer at idle. mechanical fan working from 700 rpm through 7500 rpm. is asking for problems.
If I ever need to tow heavy load up long hill at low speeds i'll switch back.
