You haven't driven the correct turbo car.
I use to get that all the time with the Reliant and Daytonas I owned Feets, people always ask "why do you waste your time with those things?"
Then they go for a ride or better yet slide behind the wheel... Like getting a wake up call from God as he slams you from behind with an 18 wheel'er.
BTW- The Reliant (135 cubic inches) was dyno'd at over 440hp to the wheels and whould just light the tires up at 80 mph when you roll into the throttle. The driver of the "chase car" when on road tests would recount how he would see the car just skirt sideways and leave yards of black rubber on RT85 when working on the calibration.
Boost is good.

Been driving lots of different +600hp street cars for years, and the ticket to having an engine like that and still enjoy it on the street is, TORQUE!..or overdrive which is the route I went on my last hotrod. Build the car with milder gears so its not anoying to drive, and build a motor that idles with what your willing to live with and makes lots of torque and will peak where you want to shift it, not neccessarily where the heads peak like a race motor. Hemis have always been king for moving big heavy cars...Just look at all the SS ones, wedges are in the 10's, hemis are in the 9's...
Personally, I hate wedge motors. I could care less if I ever worked on one again. I like having skin on my hands after pulling plugs after a run...So for me, it would be a stroked Hemi, small block or big block..They are very potent.
The enjoyment comes from reliability in the valve train, and the street manners of the car. One note though, an 8-3/4 will not live more than the first full throttle hit with a set of drag radials and +600hp.. We broke 4 of them last year in our Hemi Charger street car on drag radials...And a host of other parts. When you make big power, stock parts don't live long, and torque will always find the week link.

My thoughts are: 1. sounds good to me 2. do it to it 3. have fun I'm making 499.75 at the wheels here with a homebuilt 451 Wedge, it's a fun street car and more power would be better! I just fill it up with 93 and head down the road  My car is pretty tame and very simple compared to alot of the guys I associate with, or run into regularly Around here it is not uncommon to find a high compression, aluminum rod, multiple carb V8 car putzing around Woodward on a Saturday like it's no big deal. Or a roots blown deal. Or an EFI forced induction rig. Or a nitrous rig....and so on. You name it, they can all make the power and then some. 650 is not a lofty goal for a hemi, you won't have a problem as long as common sense is applied. You can't possibly ever have too much power  you CAN have a chassis, driveline, tires, or driver that is not able to handle it though...which you will probably want to address...in your own personalized way, in your own time.... After reading you will probably need a stronger axle 18 times or whatever it has been, I'm sure the point has been made so I'm not going to repeat it  So I say do it and enjoy yourself.... You didn't ask "how" to do it, or "what else will I need", which everyone is trying to answer their way is great and the best, etc etc....that's a discussion I won't be part of. I say "do it your way". How do you want to accomplish it?

My .030 over 440 makes 643HP at 6300RPMs and 592lbs of torque at 4400RPMs.
Can I see the details of your combination? And do you have any ET & MPH results from track to go along with it? Thanks!

Part of the fun includes seeing the general public's reaction to an old school, high compression big block with a lopy idle, especially when the exhaust cutouts are open...
There's no way to fake that with a smooth idling turbo...
Here's that ancient video of the hot rod idling. It's enough to turn heads when I pull in to the local cruise spot.

Hey, that would turn my head too. Sounds sweet Feets, especially with the whistling noise. You don't hear them like that too often.

Forget about the HP, but my car runs mid 10s in full street trim. And so I'll add that... - my wife is scared of the car after driving it around in a parking lot... and that was before I swapped the power steering for manual - one of my best friends is scared of the car after I let him make a pass at the track in it... and he backed off and only ran in the 12s - the tires are "spin happy" if you don't watch the throttle... the whole CAR is "spin happy" when the roads aren't dry - it's not tiring to drive, other than the 3" exhaust is kind of loud and there's no AC for the summer heat & humidity Big-block E bodies are simply not balanced driving machines, unless you strap 'em down w/ anti-roll bars front & back, stiff shocks, etc. And then they don't hook worth a crap at the track, because they need the weight transfer to keep from just sitting there and spinning the tires off the rims.
