700-800?? i think what limits it is the iron block but i could be wrong

 

[hj16]

93 octane - 580rwhp safely - 650+rwhp doable

Obviously the higher the octane the higher the limit. People have made 750+rwhp on 93 octane with Turbos, but their lifespan is questionable. A 88mm car just made 1000rwhp on the stock longblock with C16 and its plenty safe long as the fuel can keep up.

all depends on fuel, gas, and the tune by bob k

it's a crapshoot. Most of the high HP car's that you see last a long time (in days), aren't driven very often. If you plan on 12-15K miles a year, keep it under 600rwhp. If you plan on 1-5K miles a year, go for broke. Run as must boost as you can, just make sure you have 100+ octane in the tank.

Yup 100 octane or bust. Its a good idea to keep a couple of different tunes on your programmer. One for 93 one for 100+.

Wow, went right over my head

I guess it can handle as much as you can throw at it

I just cracked 52K on the odometer yesterday coming home and I havent had one issue and Im pushing over 500hp+ at the wheels. I started moding my car after 6K miles.....actaully I thought about this yesterday when I saw the 52K and I have to say that Ford did one hell of a job building these motors:headbang:

Damn 52K? When I saw your car I would have thought more aroun 10K

Thanks I take good care of her and she always sleeps in the garage. I still havent gotten around to putting those tires on my car yet that I got from you...but Im getting close:burnout::burnout: You had a bad ass looking ride too:biggthump

I think it depends a lot on the type of power adder too. Twin screws and roots blowers make way more heat and put more stress on the crank than say a turbo.

If you plan on 12-15K miles a year, keep it under 600rwhp.

I agree

 

[-=SVT=-]

Some times i think it is hit and miss after 650 or so with these motors. It just depends on witch day your motor was built on.

There is a twin turbo cobra 850rwhp on stock motor and he claimed to drive it 6k like he stole it and still running strong.

 

[ShelbyGuy]

yeah but is the owner a poofter

its about the owner's bottom end, not the car's...you big silly...

oh, i see now!

well, every bottom end is different. thread starter should know it better. I say it can handle a lot.

Your motor isn't even broken in yet. :lmao:

- 2.76 pulley (472rwhp) 3 weeks after purchasing new (March 2004)
- Whipple at ~18,000 miles (depending on boost, 568-600 rwhp since then)
- 89,000+ miles and 350+ quarter mile passes to date

Yeah dont you have like 70K+ on yours already

Too many variables to answer this question with any certainty.

I guess a few major questions might be:
- type of power adder(s)
- expected use for the vehicle/expected mileage per year
- type of fuel to be used
- etc.
- etc.
- etc.

Either way, there's no CORRECT answer here. Depending on many variables, I suppose somewhere between 350 and 900 rwhp.
