800 hp is streetable? i think that's pushing it imo but hey what do i know im just a doctor
its not, my 331 on 6psi will roast my et streets all the way down the block. i have all the suspension mods i can do as well as sub frames and a full cage. there is no way to make 800hp stick on the street. even with huge slicks it just isnt going to happen unless you roll into it

and that's around the number i'm shooting for i was just wondering can i get this kit to do that horsepower and not end up being some crazy 1000 horse or somethin...
he probably realized that I was right and sold his car in shame... probably too embarassed to come back and admit defeat
Hahahahahahah, Adder. Yes, I sold the car. However, I am buying it back from my friend. I am not going turbo however. It now has a 468 CI BBC with AFR Heads. About 950 to 1000 hp. I wont admit defeat, because I never even started the build. I guess I want to go fast. Should be fun to own a Heretic!

It can last a long time even at a decent pressure. Tuning & rpm will have a lot to do with how long your engine will last. If it's tuned well & you don't try to turn really high rpm you would last quite a while even at 10psi, I would say you'd be fine at 14-16psi under those circumstances if the engine was completely stock without the current upgrades. As mentioned I would recommend the head studs & a head gasket upgrade. Stock ones seem to work fairly well with decent pressure if you make sure to retorque a few times after the engine has had a chance to get up to operating temp. I always coat the headgaskets with copper spray, whether that does anything or not I have no idea. I have no testing information on holding capacity, I heard it from an engine builder long ago that owns turbo cars himself & has always used factory replacement headgaskets with no issue. I've been doing it since.

10lbs of boost from a 14g & 73mm? is the exact same thing. The difference would be in volume & a little difference in outlet temps (or a lot if the trim is chosen to run at higher pr's)
The big issue I would have is the size of the turbos. 73mm doesn't tell everything. I'm guessing the 73mm is the inducer. I would say more than likely those turbos are sized quite big for the engine as it stands now.

It won't make near 1200hp. Advertised hp with turbos are to give someone an idea of what they support. Forced induction cars behave quite well on the street compared to n/a of the same power.

In the real world where it has to actaully has to push a car through the wind and from a dead stop it turns out to be a differant story when that dyno queen can't bust into the 11's. Horsepower doesn't mean Crapola. The only thing it does is give people and idea of power. Torque moves the car and cubic inches and cyl pressure create torque. Excessive cyl pressure, excessive heat and excessive rpm is what kills engines.
I don't think that dyno queen busting into the 11's has to do with it having to be at 11000rpm to produce 750 hp. I think that has a great deal to do with getting that power to the ground & getting up to the higher rpm. There are a lot of evo & dsm's proving that. There are some turbo 4 cylinder mustangs also doing so as well if you prefer the rwd mustang background. jon huber is a widely known one in the mustang world.
& while I do agree with some of what you say. Your hp doesn't mean crapola is quite wrong imo. I realize that hp is a measurement of torque with rpm factored in, but personally I think people would be better off if they were told to look at the hp numbers at a given rpm for how powerful the engine is since that factors in fuel & air intake at the rpm where as torque more so tells how efficient the engine is at that given rpm. If I were building an engine & aiming to get the best setup for x scenario I would be paying more attention to torque numbers, but if i were judging what engine would make my car faster & was given peak numbers I would pay more attention to hp.

Yes, the hypereutectic pistons hold up fairly well to boost aswell though. I wouldn't recommend doing it with cast. & one or two turbos will depend on what you want. A twin turbo kit is no more damaging than a single. Twins have the advantage of spooling faster due to less rotating mass & superior header design over a single. Given cost though, a single good turbo can be a better option than two so/so turbo's when it comes to ball bearing vs journal. Personally I still prefer journal bearing turbos mostly because of parts availability & cost.
