From what I'm seeing it's all in the tune. But safely on stock turbo 300-340ish a little more with a bigger turbo without having to worry about it going boom.

All Depends on fuel and tune.350-380 on stock turbo low 4 to 450 with big turbo.

Aside from depending on tune. these answers are totally different. your minimum is his maximum and visa versa. :shrug:

Yea your going to get a lot of different answers in here.

I ran 350+ on stock turbo without a problem. I'm running 450 big turbo no problem. Key is good fuel (like E85)/meth.

Answers could very because people might be thinking max power based on setup (bolt ons, turbo, etc). I've seen tuners state they won't go past 450hp on a stock engine.

Higdominator what's the most horsepower you were able to get out of the stock turbo on 93 octane pump gas reliably? Can you give me an idea of your boltons when you hit the 11.84? Race gas? Slicks?

I never ran 93. I used E30. I had intake, down pipe, intercooler, and some MT drag radials. I also would recommend BMR diff and cradle lockouts and vertical links. There's no use pushing a car for traction if it's going to windup and unload/virbrate/ etc.

How was the NVH with the cradle lockout and vertical links?

Slight increase, nothing compared to solid bushings. The biggest NVH contributor in my car is the Steeda motor mounts.

I have no idea how much power my car makes, but ive gone 117 mph at 3785 lbs with the stock turbo on race fuel. The engines are all about the fuel, you gotta have good fuel. If you don't detonate them they seem to be able to take a lot of power. People that ask how much power on 91 or 93, the answer is, till your start detonating it, thats how much power your gonna get out of it. That might be 375, might be 400, depends on how big of balls you and our tuner have. Cylinder pressure increases exorbitantly with detonation, if you don't reach that point, you can keep the rods and pistons in these engines and make pretty good steam, they are really surprising me.

I dynoed 370trq 270 hp on shell 91 here's a quick run with a GT I had, engine runs smooth and feels like I can pump some more out of it
