Ok, I'll bite. It would seem to me that 1500 hp is 1500 hp regardless of how it is made, be it a Buick V6 or small block V8 Chevrolet. This should be especially true when we are talking TR motors. It isn't like our V6s are so high strung that they don't put out enough bottom end power for a street motor! A "street" 1500 hp Buick turbo V6 shouldn't be any different from a "street" 1500 hp V8 Chevy small block. The bottom line is that the whole idea of driving a car in this HP range on the street is silly. It's neither practical because of the high cost/maintenance nor is it safe/smart!
I'll ask a friend of mine if his is still 4 sale. It is a little to fast for him.

It's a bowtie block 377 or 383 built by Duttweiler, twin 76's, and whatever else you see. Made somewhere around 1400hp+.
He hasn't had to many passes on it. He's in SoCal

You do not need even over 1000 to the wheels to run 8s. Since Sod and Manny Bogosian do not get on the Buick boards, or the internet for that matter, I will speak on their behalf from what I have seen and what I have been told.
Sod and Manny have an 87 GN that runs a Stage-II 274-ish CI, with twin T-66s. It runs a 2 speed now. Used to run a th-400. The car has been dynoed at 890 horsepower to the wheels at 22 psig boost. Just today at Las Vegas Motor Speedway, Manny ran a few 8.80s. That was at 24 psig boost though. This is a stock rear suspension car (9 inch housing though). It does it on 10.5 slicks.
Almost forgot, it is licensed and has current tags. Yes he drives it on the street. It is not much fun, since it roasts the tires just about whenever he wants to though.
They are in La Puente California. Give Sod a call at 626 855 1154 to see if he can do this for you too.

Almost forgot. If you like really fast cars, look into the 93.5-98 Toyota Supras. Also known as the MKIV Supras. You can get 1000+ to the wheels out of these cars no prob. There are a few that have gone 8s with street driven cars.
Good luck on your search!

So you're saying Chow's car is no more streetable than Duttweilers car when he ran the stage 2 in the red T? Are you serious?? All things being equal, there is no replacement for displacement. I bracket raced a mid 8 second Vega for quite a while that had a blown BBC. A 1500hp V6 is NOT the same as a 1500hp V8 or V10. The horsepower number does not tell the whole story. It will be easier for a bigger engine to make X amount of power, all things being equal. You say our motors are high strung and they will have enough bottom end power for the street in a 1500hp application. Sorry, but I haven't seen a 1500hp stage 2 V6 that made any appreciable power below 5000rpm. Back when Kenny went 7.20, Turbo High Tech magazine printed a copy of his dyno sheet. It most certainly WAS high strung! Years ago I met him in Englishtown at the GN vs. Mustang meet. We chatted for a bit in his trailer about his car. On one particular pass his car nosed over on the starting line like it ran out of gas. He told me that was because he tried leaving BELOW 8000rpm! Said the car didn't want to move unless it was at least taching 8300rpm. The big twin T66s require a ton of exhaust energy to spool and a 274" V6 needs to be screaming to do it.
All that being said, Ben will be much better off with a turbo V8 rather than a V6 for his particular application. My Vega was a BLAST on the street. I can't imagine a huge single turbo V6 being much fun below 5000rpm.
Don't assume that he's going to be "racing" it on the street. The more HP people build into their cars the less chance that they will race it in the street or even do a burn out. I have several friends that have 1000HP cars and they drive them on the street occasionally and they won't even do a burnout to show off. They will drive it to work or to the local Sonic and that's it. The more HP you have the more you respect it and the less of a need to show it off b/c everyone already knows how much it has..
I say build the 1500hp the way it makes sense to you and drive it anywhere you want!!

Yah, that was pretty much the problem with my Supra. It had a 6-speed and didn't make real power until 4800 RPM. I had assumed the larger displacement of the Buick V6 would make the powerband more tractable.

Ben,
You may be able to get by with a pair of 3 bolt style turbos like two PT70 GTQ Precision windmills (or perhaps even smaller). They spool quicker than their 4 bolt cousins and should support enough power between the two of them to get the job done, especially on a 270+ci Stage 2 engine. You can also go with a less-than-full-weight car which will require less power to be propelled into the 8s. This would mean you wouldn't have to have such a wild engine combo which may make a more liveable "street" car.
I'm sure Duttweiler can shed more light on the subject than we can. He built my buddys stage 2 engine which pushes a 3000+lb. Olds to low-mid 8s with a Q trim T76 (he may have upgraded to an 88 by now, though). Again, i'm not saying the power can't be made, we all know it can. However, making it fun on the street is the key. 8 second cars are maintainence whores (trust me). The more time you spend on the street versus under the hood, the better.

With all due respect, you can buy mine listed at the above link.
Cannot duplicate for the money.

Yup and I've personally seen Ricardo drive it on the street........
He scares some people when he does that though!
I can see owning a 8 second street/strip car, hopefully when I get my stage II problems sorted out I will be able to say I own one.
Unless you have driven a TR capable of 130+MPH in the 1/4 and have experienced the unexpected loss of traction at any given time, I believe having a low 10, 9 or 8 second car (for the street) is only something as good as a trophy. You plain do not build something like this for the street IMHO. Even my stock block really should not be on the street, it will/can shear the 28x12.5 E.T. Streets loose in 3rd gear.
A car like this belongs at the track. I respect others safety and unless you are able to contain yourself and fear the car, you should stay off the street.
I do agree with a larger CI motor for the task though. This is a good topic.

Now that's what I'm talking about! Of course, it's not a project car if it's already built, but I'm willing to overlook that point. I'll drop you a line straightaway.
For those in Cali, how have out-of-state modified vehicle purchases been handled? My perusal of the current DMV code indicates you need to smog it once upon entry...?

Guys,
As you can see, Ben is a mature, grown adult who already has/had some pretty wild street cars (1200hp Viper, for one). We aren't talking about a teenager taking his dads 8 second race car out for a joy ride. I have driven truely quick/fast cars on the street with little drama. Drive it like a normal human being and you are no more likely to wreck than in a stocker. Besides, i'm sure Ben isn't building this car as a daily driver.
After a certain point, it really doesn't matter how much power you make. Part-throttle wheelspin is the same in an 11 second bolt-on as it is a 9 second race car. My T-Type can get out of hand almost as quickly as my 10 second GN.
Bottom line, Ben is no stranger to powerful street cars. Lighten up on him a tad.
