Criteria:

1. Has to be a 928 block
2. No nitrous
3. Has to be streetable, not necessarily a daily driver, but drivable.
4. Actual 1000 BHP, not the equivalence by making the car lighter


What year/block would you use, OB? S4? GT? GTS?
What internal modifications, ie stroker, compression, etc?
What external modification, injectors, ITB, etc?
What power adder(s), turbo, twin turbo, SC, twin SC, or combination?
How durable would this motor be?


Also, what about the rest of the driveline, what clutch, TT, transmission, gearing, etc?

Ballpark cost of your entire driveline?

And lastly, what model would you put the engine in?

I'm trying to make a list and plan of action for when I'm rich.

 

the best chance for a 1000hp 928 would be one engine for each wheel. this has been done. i've seen it. i'm serious. a 928.

 

NA huh?

In dream world. F1 style intake, mounted to F1 style heads and cams and shorten the stroke to 50mm. Make it rev to 15,000rpm. Maybe even do one of those custom cranks that make them Flat.

F1 style clutch, driveline attaching to one of those T56 transmissions or Nascarboxes.

1000hp. can you imagine? how would you stop it?

 

I didn't say NA. I'm thinking stroker motor with Kuhn's twin turbo to start.

And thanks for nothing BB, I find it harder and harder to take you seriously.

 

I think 1000bhp would not be streetable. I'm almost certain it canot be done with pump gas.

I think the only way possible would be with turbos (twin, maybe even four).

Everything would have to be modified... I mean everthing. There is one guy who's close. Dyno'd 670 at the rear wheels which is just shy of 800 crank HP. He's running 30psi on a supercharger. Everything is stock except he uses 951 pistons.

1000 hp at crank? Interesting question.

I assuming a whole lot below and punching numbers to various web calculators.

To get 1000 hp at 12.5 AFR and 0.55 BSFC, one needs to flow about 1600 SCFM of air. To fit that in a 5.0 liter engine that has a natural VE of 90% at 7000 rpm, one needs about 34 psi of boost. Two GT3582R turbos would deliver that, about 7000 lb/h at a pressure ratio of 3.3. With 72% efficiency, the air coming out of those turbos would be about 380 F, so one would need two big air-to-air intercoolers. Let's say one would get the temperature down to about 150 F with those. Static compression ratio of say 7.5, moderate size cam (say 270 duration measured at 0.005"), and race gas might do it. Then, one would need about 100 lb/h rated injectors and 67 psi fuel pressure to be able to get the duty cycle to 90% or below. One would need a serious fuel pump to flow, for example the biggest from Fuelab. A rpm and gear based boost control, and a whole lot of tuning should get one there.

I think 1000hp is pushing it a bit.

 

Hi

Without Nitrous as a choice..you are NOT going to do it on petrol....

I could build any 928 engine to run Nitromethane and Methanol with a huge blower and fuel pump for 1000 hp quite easily...

BUT.....it would last maybe 2 or 3 ..1/4 s at best before the engine or tranny blew....

The reason that Nitrous works for huge hp is that the trick is in the controller, where you can bring in the extra hp, extremely smoothly and evenly, so no massive torque hit.....and its torque that kills engines not hp....

So I doubt you could do it on twin or quad turbos or blowers on petrol.....

Maybe 800 though....

So its back to Nitrous lol....but I would say that

All the best Brett

 

What about getting that power to the ground?????

 

This thread should be amusing.

 

Hi

Oh thats easy...Top Fuel drag slicks, matched to a Lenco 2 speed with a reverser...lol...

All the best Brett

 

Nobody has ever made 1000 from a 5.0 on gas huh.
Hell there are folks that have done that with 2 valve heads, push rods and race gas.

To say it cant be done with out N2O is pure horse puckey

 

That "guy" is over 700 now I think. He will be WAY over 700 very soon when he works out "the spark".

And with the drive losses of the SC, he is close to 1000 Bhp.

Now I do believe that the stock block could handle 1000hp for at least a moderate amount of time.

To the OP:

Stock block, forged pistons (optional) some block strengthening, and 89+ heads with some sort of cam change.

LOTS of boost. Probably turbos.

Aftermarket EFI.

 

Yeah, most of the cars out there who put down 1000 horsepower are on turbos. And most of them tune them for race gas, do the dyno run, and then tune them back to a "street tune". Not that many people are running around with 1000 horsepower all the time. Otherwise their engines would not last very long. It's fun for bragging rights, but not very streetable...
